- The patient fell approximately 15 feet onto concrete
Correct answer: The patient fell approximately 15 feet onto concrete
A fall of approximately 15 feet onto concrete describes the mechanism of injury, which is the force or energy that caused harm to a trauma patient. Mechanism of injury considers the type of force, its strength, and where it was applied to the body. Back pain, anxiety, and diaphoresis are signs and symptoms the patient presents with, and osteoporosis is past medical history, not the mechanism.
- While sizing up the scene for a patient who feels short of breath with no signs of trauma, what are you primarily trying to determine?
- The nature of the illness
- The exact tidal volume
- The Glasgow Coma Scale score
- The mechanism of injury
Correct answer: The nature of the illness
For a medical patient with no trauma, scene size-up focuses on determining the nature of the illness, which is the general type of medical condition or complaint the patient is experiencing. The nature of illness is gathered from the patient, family, bystanders, and the scene itself. Mechanism of injury applies to trauma patients, while tidal volume and the Glasgow Coma Scale are measured later during patient assessment.
- What is the key difference between mechanism of injury and nature of illness?
- Mechanism of injury describes vital signs; nature of illness describes the chief complaint
- Mechanism of injury applies to medical patients; nature of illness applies to trauma patients
- Mechanism of injury is assessed at the hospital; nature of illness is assessed on scene
- Mechanism of injury is the force causing a traumatic injury; nature of illness is the type of medical problem affecting a patient
Correct answer: Mechanism of injury is the force causing a traumatic injury; nature of illness is the type of medical problem affecting a patient
Mechanism of injury is the force or energy that caused a traumatic injury, while nature of illness is the general type of medical condition affecting a patient who is sick rather than hurt. The EMT determines mechanism of injury for trauma calls and nature of illness for medical calls during scene size-up. Both are evaluated on scene, not at the hospital, and neither term refers to vital signs.
- You are dispatched to a report of a person down in a parking lot. As you pull up, you see a man standing over the patient yelling and waving a knife. What is your most appropriate action?
- Approach quickly to reach the patient before the situation worsens
- Begin treating the patient from inside the ambulance
- Stage at a safe distance and request law enforcement
- Use lights and siren to scare the aggressor away
Correct answer: Stage at a safe distance and request law enforcement
Staging at a safe distance and requesting law enforcement is correct because scene safety always takes priority over patient access. An armed, aggressive bystander makes the scene unsafe, and EMTs must not enter until police secure it. Approaching, attempting to scare the aggressor, or trying to treat from the ambulance all place the crew at risk; you cannot help the patient if you become a victim.
- You are dispatched to a two-car collision. During your scene size-up, how do you determine the number of patients?
- Count only the drivers of the involved vehicles
- Wait until each patient calls out to you
- Count only the patients who are visibly bleeding
- Count the occupants of every involved vehicle and any pedestrians or bystanders who may be injured
Correct answer: Count the occupants of every involved vehicle and any pedestrians or bystanders who may be injured
Determining the number of patients means accounting for all occupants of every involved vehicle plus any pedestrians or bystanders who may be hurt. An accurate count drives the decision about whether additional resources are needed and prevents missing a patient who was ejected or is unresponsive. Counting only those bleeding, only drivers, or only those who call out risks overlooking critical patients.
- You arrive to find four patients at a collision but only one ambulance crew. What should you do during scene size-up?
- Request additional resources before committing to patient care
- Wait for the patients to be triaged by a bystander
- Begin treating the most seriously injured patient immediately
- Transport the first patient you reach and return for the others
Correct answer: Request additional resources before committing to patient care
Requesting additional resources before committing to patient care is correct because recognizing that the number of patients exceeds your capacity is a core function of scene size-up. Calling early for more ambulances, supervisors, or mutual aid prevents delays in care for everyone. Committing to one patient, transporting prematurely, or relying on bystanders leaves the remaining patients without timely help.
- During scene size-up for a patient found unresponsive at the bottom of a staircase, why should you consider spinal stabilization?
- Because it is required for every unresponsive patient regardless of cause
- Because all medical patients require spinal precautions
- Because the mechanism of injury suggests possible spinal trauma
- Because spinal stabilization speeds up transport
Correct answer: Because the mechanism of injury suggests possible spinal trauma
A fall down a staircase is a mechanism of injury that suggests possible spinal trauma, so the EMT should consider manual in-line spinal stabilization as part of scene size-up. Recognizing a significant mechanism early prompts the crew to protect the spine before moving the patient. Spinal precautions are based on mechanism and findings, not applied to every medical or unresponsive patient automatically.
- You respond to a kitchen where a person collapsed. As you enter, you smell a strong odor of natural gas. What is the priority action?
- Administer oxygen to the patient in place
- Quickly remove the patient and begin assessment outside
- Remove yourself and bystanders, then call for the appropriate resources
- Open the windows and continue your assessment in the kitchen
Correct answer: Remove yourself and bystanders, then call for the appropriate resources
Removing yourself and bystanders and calling for the appropriate resources is correct because a natural gas odor signals an explosion and asphyxiation hazard. Scene safety requires the EMT to retreat and summon the fire department or hazmat team rather than enter the danger zone. Even removing the patient yourself or opening windows exposes you to the hazard; specially trained and equipped personnel must make the scene safe first.
- Which of the following best describes body substance isolation (BSI)?
- Personal protective measures taken to prevent contact with a patient's blood and body fluids
- Quarantining the crew after exposure to an infectious disease
- Isolating a contagious patient in a negative-pressure room
- Decontaminating the ambulance after every call
Correct answer: Personal protective measures taken to prevent contact with a patient's blood and body fluids
Body substance isolation refers to the personal protective measures, such as gloves, eye protection, gowns, and masks, that an EMT takes to prevent contact with a patient's blood and body fluids. BSI is part of standard precautions and is initiated during scene size-up before patient contact. Negative-pressure rooms, ambulance decontamination, and crew quarantine are related infection-control concepts but are not the definition of BSI.
- You are dispatched to a motorcycle crash. The rider struck a guardrail at highway speed. Based on the mechanism of injury alone, what should you anticipate?
- An isolated medical complaint
- A minor injury requiring only a bandage
- No need for additional resources
- The potential for serious, multi-system trauma
Correct answer: The potential for serious, multi-system trauma
A high-speed motorcycle crash against a guardrail is a significant mechanism of injury, so the EMT should anticipate the potential for serious, multi-system trauma. Motorcyclists lack the protection of an enclosed vehicle, and high-energy impacts commonly cause severe injuries even when the patient initially appears stable. The mechanism alone justifies a high index of suspicion and likely additional resources.
- You arrive at a residence for an elderly woman with weakness and confusion. There is no sign of trauma. How is the nature of illness best determined?
- By gathering information from the patient, family, bystanders, and the scene
- By waiting for hospital lab results
- By assuming the worst possible diagnosis
- By measuring the mechanism of injury
Correct answer: By gathering information from the patient, family, bystanders, and the scene
The nature of illness is best determined by gathering information from the patient, family, bystanders, and clues at the scene, such as medications or home oxygen. For a medical patient, these sources help the EMT understand the general type of problem before detailed assessment. Mechanism of injury applies to trauma, and the EMT forms an impression on scene rather than waiting for hospital results.
- You respond to a structure fire where bystanders report a person trapped inside. Heavy smoke is showing from the windows. What is your role during scene size-up?
- Direct bystanders to enter and pull the patient out
- Position the ambulance directly in front of the doorway
- Enter the structure to perform a rapid search
- Stage in a safe area and allow fire personnel to handle the rescue
Correct answer: Stage in a safe area and allow fire personnel to handle the rescue
Staging in a safe area and allowing fire personnel to handle the rescue is correct because an active structure fire is beyond the EMT's scope and protective equipment. Scene size-up requires recognizing that specially trained and equipped rescuers must control the hazard first. Entering, sending bystanders in, or parking in the collapse and operations zone all create unacceptable danger.
- During the scene size-up of a fall victim, the EMT determines that the patient fell from standing height while walking. How should this mechanism be classified?
- A nature of illness rather than a mechanism
- A significant mechanism of injury requiring full spinal precautions automatically
- A reason to cancel the response
- A low-energy mechanism that may still warrant assessment for injury
Correct answer: A low-energy mechanism that may still warrant assessment for injury
A fall from standing height is a low-energy mechanism of injury that may still warrant assessment for injury, particularly in older adults who can fracture with minor force. Classifying the mechanism helps the EMT gauge the index of suspicion without overcommitting resources. It is still a mechanism of injury, not a nature of illness, and a fall always merits patient assessment rather than cancellation.
- You are dispatched to an apartment for an unknown medical problem. As you approach the door, you hear shouting and breaking glass inside. What should you do?
- Knock loudly and announce yourself before entering
- Enter cautiously with your portable radio ready
- Retreat to a safe location and request law enforcement
- Force entry to reach the patient quickly
Correct answer: Retreat to a safe location and request law enforcement
Retreating to a safe location and requesting law enforcement is correct because sounds of violence indicate an unsafe scene. Scene safety during size-up means the EMT does not enter a potentially violent environment until police secure it. Forcing entry, knocking and entering, or entering cautiously all place the crew at risk of becoming victims themselves.
- What information from dispatch helps the EMT begin the scene size-up before arriving on scene?
- The hospital's bed availability
- The patient's exact diagnosis
- The patient's insurance information
- The location, type of call, and any known hazards
Correct answer: The location, type of call, and any known hazards
The location, type of call, and any known hazards reported by dispatch let the EMT begin forming a scene size-up before arrival. This pre-arrival information guides decisions about precautions, additional resources, and the safest approach. A definitive diagnosis, insurance details, and hospital bed status are not part of the scene size-up an EMT performs.
- You arrive at a chemical plant for a worker who collapsed. A supervisor points to a cloud of vapor near the patient. What is the safest action?
- Hold your breath and quickly drag the patient clear
- Approach from downwind to avoid the supervisor
- Stage uphill and upwind, then request a hazmat response
- Don a non-rebreather mask and approach the patient
Correct answer: Stage uphill and upwind, then request a hazmat response
Staging uphill and upwind and requesting a hazmat response is correct because a visible vapor cloud is a hazardous materials emergency outside the EMT's protective capability. Positioning uphill and upwind keeps the crew out of the contaminated area while specially trained teams manage it. A non-rebreather mask does not protect against inhaled toxins, and approaching the cloud or holding your breath endangers the crew.
- You respond to a school where multiple children became ill after lunch. On arrival you find eight symptomatic patients. What is your priority during scene size-up?
- Begin a detailed assessment of the first child you see
- Transport all eight patients in your single ambulance
- Assume only one patient is truly sick
- Recognize a possible mass-casualty situation and call for additional resources
Correct answer: Recognize a possible mass-casualty situation and call for additional resources
Recognizing a possible mass-casualty situation and calling for additional resources is correct because the number of patients greatly exceeds a single crew's capacity. Identifying the total patient count and requesting help early is a core scene size-up task that prevents care delays. Focusing on one child, overloading the ambulance, or downplaying the situation would compromise patient outcomes.
- While performing scene size-up at a collision, you note a downed power line draped across the involved vehicle. What is the correct action?
- Approach the vehicle to check for a pulse
- Have a bystander pull the patient out through the window
- Move the power line aside with a dry wooden tool
- Instruct occupants to stay in the vehicle and request the utility company
Correct answer: Instruct occupants to stay in the vehicle and request the utility company
Instructing occupants to stay in the vehicle and requesting the utility company is correct because a downed power line presents a lethal electrocution hazard. Scene size-up requires recognizing that energized lines must be confirmed de-energized by trained personnel before anyone approaches. Moving the line, having bystanders pull the patient, or approaching the vehicle all risk electrocution.
- You arrive for a patient who fell while skateboarding and is now sitting up holding their wrist. There is no helmet and no loss of consciousness reported. What does scene size-up suggest about the mechanism?
- The mechanism is a nature of illness
- The mechanism is a significant multi-system trauma requiring helicopter transport
- The mechanism appears isolated and low-to-moderate energy, focused on the extremity
- The mechanism is irrelevant because the patient is conscious
Correct answer: The mechanism appears isolated and low-to-moderate energy, focused on the extremity
The mechanism appears isolated and low-to-moderate energy, focused on the extremity, given a skateboarding fall onto an outstretched arm with the patient alert and sitting up. Sizing up the mechanism helps the EMT direct the assessment and resource decisions appropriately. The mechanism is always relevant, it is a mechanism of injury rather than a nature of illness, and the presentation does not yet indicate multi-system trauma.
- You are dispatched to a medical call. Which scene clue would most strongly help you determine the nature of illness?
- A deployed airbag in the driveway
- Skid marks on the roadway outside
- A damaged guardrail near the home
- A nebulizer machine and multiple inhalers on the kitchen table
Correct answer: A nebulizer machine and multiple inhalers on the kitchen table
A nebulizer machine and multiple inhalers on the kitchen table strongly suggest a respiratory nature of illness, guiding the EMT's impression of a medical patient. Environmental clues like medications and equipment help determine the nature of illness during scene size-up. Skid marks, a damaged guardrail, and a deployed airbag are mechanism-of-injury clues that apply to trauma, not a medical nature of illness.
- During scene size-up, when should an EMT request additional resources?
- Only after transport has already begun
- As soon as the size-up reveals a need that exceeds current capabilities
- Only after completing a full patient assessment
- Never, since one crew can handle any scene
Correct answer: As soon as the size-up reveals a need that exceeds current capabilities
Additional resources should be requested as soon as the scene size-up reveals a need that exceeds the crew's current capabilities, such as extra ambulances, fire, rescue, or law enforcement. Early requests reduce delays because help takes time to arrive. Waiting until after assessment or transport, or assuming one crew can manage everything, can leave patients without timely care.
- You arrive at a residence and the dispatcher noted a report of an aggressive dog on the property. As you walk up, a large dog charges toward you. What is the appropriate action?
- Retreat to the ambulance and request the owner or animal control to secure the dog
- Attempt to calm the dog with food
- Continue toward the patient while making eye contact with the dog
- Push past the dog to reach the door
Correct answer: Retreat to the ambulance and request the owner or animal control to secure the dog
Retreating to the ambulance and requesting that the dog be secured is correct because an aggressive animal is a scene hazard. Scene safety during size-up includes recognizing animal threats and not approaching until the danger is controlled. Continuing toward the patient, attempting to feed the dog, or pushing past it all risk injury that could remove the EMT from service.
- You respond to a collision involving a tanker truck displaying a placard with a hazardous materials identification number. What does the placard tell you during scene size-up?
- That a hazardous material may be involved, requiring special precautions and resources
- The exact number of patients on scene
- The mechanism of injury for each occupant
- The nearest appropriate hospital
Correct answer: That a hazardous material may be involved, requiring special precautions and resources
The placard tells the EMT that a hazardous material may be involved, requiring special precautions, safe positioning, and a hazmat response. Recognizing placards during scene size-up alerts the crew to potential chemical dangers before approaching. The placard does not reveal the patient count, individual mechanisms of injury, or hospital destination.
- At the scene of a building collapse, what should the EMT consider regarding the number of patients?
- The number is fixed at the count given by dispatch
- The number includes only those who can walk to you
- The number may be higher than initially reported and may include trapped victims
- The patient count does not affect resource decisions
Correct answer: The number may be higher than initially reported and may include trapped victims
At a building collapse, the EMT should consider that the number of patients may be higher than initially reported and may include trapped or hidden victims. An accurate, dynamic patient count drives decisions about calling rescue teams and additional ambulances. The count is not fixed by dispatch, must include non-ambulatory and trapped patients, and directly affects resource needs.
- You are dispatched to a patient with chest pain. On arrival the scene is calm and safe, with no trauma evident. After taking standard precautions, what should you determine next as part of scene size-up?
- The patient's discharge plan
- The mechanism of injury
- The need for spinal immobilization
- The nature of the illness
Correct answer: The nature of the illness
After taking standard precautions on a safe medical scene, the EMT should determine the nature of the illness, since chest pain with no trauma indicates a medical problem. Establishing the nature of illness shapes the assessment and care that follow. Mechanism of injury and spinal immobilization apply to trauma, and a discharge plan is not part of prehospital scene size-up.
- You arrive at a nighttime collision on a dark rural road. Which scene-safety measure best protects you and your crew?
- Positioning the ambulance to shield the scene and wearing high-visibility reflective gear
- Standing in the travel lane to direct oncoming traffic
- Parking well past the scene to keep the road clear
- Turning off all emergency lights to avoid distracting drivers
Correct answer: Positioning the ambulance to shield the scene and wearing high-visibility reflective gear
Positioning the ambulance to shield the scene and wearing high-visibility reflective gear is correct because traffic is a leading hazard at roadway incidents. These measures make responders visible and create a physical barrier between traffic and the work area. Turning off warning lights, standing in the travel lane, or parking past the scene all increase the risk of being struck.
- During scene size-up, an EMT notes a starred windshield and a bent steering wheel in a vehicle. What does this finding represent?
- A nature of illness
- An indication the patient is uninjured
- A reason to skip the primary assessment
- Mechanism-of-injury clues suggesting significant force to the patient
Correct answer: Mechanism-of-injury clues suggesting significant force to the patient
A starred windshield and bent steering wheel are mechanism-of-injury clues suggesting significant force was transmitted to the patient, raising suspicion for head, chest, and abdominal injuries. Reading these clues during scene size-up guides a thorough assessment. They are not a nature of illness, do not indicate the patient is uninjured, and increase rather than eliminate the need for assessment.
- You are dispatched to an overdose call at a known drug house. Dispatch advises the scene is not yet secured by police. What should you do?
- Send one crew member in to assess while the other waits
- Stage nearby until law enforcement reports the scene is secure
- Approach the back entrance to avoid being seen
- Enter immediately because overdose is time-critical
Correct answer: Stage nearby until law enforcement reports the scene is secure
Staging nearby until law enforcement reports the scene is secure is correct because an unsecured potentially violent scene takes priority over rapid patient access. Scene safety during size-up means the EMT does not enter until police confirm it is safe, even for time-critical calls. Entering, using a back entrance, or splitting the crew all expose responders to danger.
- What does scene size-up determine for a trauma patient that it does not determine for a typical medical patient?
- Whether the scene is safe
- Whether to take standard precautions
- The mechanism of injury
- The nature of the illness
Correct answer: The mechanism of injury
For a trauma patient, scene size-up determines the mechanism of injury, the force that caused the harm, which is not relevant for a typical medical patient. Both trauma and medical calls still require standard precautions and a scene-safety evaluation. The nature of illness is the medical-patient counterpart to mechanism of injury, so it is not the unique trauma element.
- You arrive at a swimming pool where a person is reported to have drowned. The patient is still in the water. What should the EMT recognize during scene size-up?
- The patient should be left until the water is drained
- Water hazards never affect EMS scene safety
- A water rescue may require specially trained personnel and a safe approach
- The EMT should immediately jump in to retrieve the patient
Correct answer: A water rescue may require specially trained personnel and a safe approach
The EMT should recognize that a water rescue may require specially trained personnel and a safe approach, because untrained responders entering the water risk becoming victims. Scene size-up includes identifying water hazards and requesting appropriate rescue resources. Jumping in without training is dangerous, water hazards clearly affect safety, and the patient must be reached promptly by qualified rescuers.
- A bystander flags you down for a collision around the corner from your dispatched address. What should you do regarding the number of patients and resources?
- Cancel your original call immediately
- Update dispatch about the additional incident and reassess resource needs
- Ignore the second scene and proceed to the original call
- Assume the two scenes have the same number of patients
Correct answer: Update dispatch about the additional incident and reassess resource needs
Updating dispatch about the additional incident and reassessing resource needs is correct because the number of patients and scenes has changed. Scene size-up is dynamic, and an unexpected second incident may require more units. Ignoring it, canceling the original call without information, or assuming identical patient counts all risk leaving patients without care.
- You respond to a patient with difficulty breathing in a poorly ventilated basement where a gasoline generator is running. What hazard should you identify during scene size-up?
- A violent-patient threat
- A water rescue hazard
- Possible carbon monoxide accumulation
- An obvious traumatic mechanism of injury
Correct answer: Possible carbon monoxide accumulation
Possible carbon monoxide accumulation is the hazard to identify, because a fuel-powered generator running in an enclosed space produces this odorless, deadly gas. Recognizing the hazard during scene size-up prompts the EMT to remove the patient to fresh air and ensure crew safety. There is no mechanism of injury, water hazard, or violence indicated in this scenario.
- During scene size-up, which sequence of considerations is most consistent with the standard approach to evaluating an emergency scene?
- Mechanism of injury, then defibrillation, then scene safety
- Number of patients first, then standard precautions, then a complete history
- Patient's vital signs, then scene safety, then transport decision
- Standard precautions and scene safety, then mechanism of injury or nature of illness, then number of patients and resources
Correct answer: Standard precautions and scene safety, then mechanism of injury or nature of illness, then number of patients and resources
The sequence of standard precautions and scene safety, then mechanism of injury or nature of illness, then number of patients and resources reflects the standard scene size-up approach. The EMT protects themselves and confirms safety before evaluating what happened and how much help is needed. Vital signs, history, and treatments belong to the patient assessment that follows scene size-up.
- You arrive at a domestic disturbance where police have already secured the scene. A patient has minor injuries. What does the secured scene allow you to do during size-up?
- Assume there are no further hazards ever
- Skip standard precautions entirely
- Discontinue communication with law enforcement
- Safely proceed with determining the nature of injuries and number of patients
Correct answer: Safely proceed with determining the nature of injuries and number of patients
A scene secured by police allows the EMT to safely proceed with determining the mechanism and nature of injuries and the number of patients. Confirming scene safety is a prerequisite for the rest of the size-up and patient care. Standard precautions are still required, hazards can still change, and maintaining communication with law enforcement remains important.
- You are dispatched to a worker who fell into a grain silo. What special consideration applies during scene size-up?
- This may be a confined-space rescue requiring specially trained teams
- Scene safety does not apply to agricultural settings
- This is a routine fall requiring no special resources
- The EMT should enter the silo immediately
Correct answer: This may be a confined-space rescue requiring specially trained teams
This may be a confined-space rescue requiring specially trained teams, because silos pose entrapment, engulfment, and oxygen-deficiency hazards. Identifying a confined-space situation during scene size-up keeps untrained responders from entering a deadly environment. It is not a routine fall, the EMT must not enter without proper training and equipment, and scene safety applies everywhere.
- A patient is found unresponsive with no witnesses and no obvious signs of trauma or injury. How should the EMT approach mechanism of injury versus nature of illness during scene size-up?
- Assume a traumatic mechanism and apply a tourniquet
- Search the scene for clues to distinguish a medical nature of illness from a possible mechanism of injury
- Conclude the patient has a nature of illness with no further investigation
- Ignore both since the patient is unresponsive
Correct answer: Search the scene for clues to distinguish a medical nature of illness from a possible mechanism of injury
The EMT should search the scene for clues to distinguish a medical nature of illness from a possible mechanism of injury, since an unwitnessed unresponsive patient could be either sick or hurt. Evidence such as medications, a fall location, or trauma helps clarify the cause. Assuming trauma and applying a tourniquet without bleeding, ignoring both, or concluding without investigation could all lead to inappropriate care.
- You respond to a multi-vehicle pileup in dense fog on a highway. What is a primary scene-safety concern during size-up?
- The patients will refuse care
- Additional collisions from oncoming vehicles that cannot see the scene
- The ambulance will run out of fuel
- The patients are likely uninjured
Correct answer: Additional collisions from oncoming vehicles that cannot see the scene
Additional collisions from oncoming vehicles that cannot see the scene are a primary scene-safety concern in dense fog. The EMT must position apparatus to protect the scene, use warning devices, and remain alert, because secondary crashes endanger responders and patients. Refusals, fuel, and an assumption that patients are uninjured are not the dominant safety issue here.
- During scene size-up at a residence, you find a single patient who is sick, but you also notice an infant in distress nearby. How does this affect your size-up?
- The infant does not count as a patient unless dispatch said so
- You should transport both with no additional help
- You must update the number of patients and request additional resources
- You should ignore the infant and focus on the dispatched patient
Correct answer: You must update the number of patients and request additional resources
You must update the number of patients and request additional resources, because scene size-up requires accounting for every patient present, including those not reported by dispatch. Recognizing a second patient in distress changes the resource picture immediately. Ignoring the infant, transporting both without help, or discounting an undispatched patient would compromise care.
- You arrive at a scene where a patient has fallen from a roof. As you complete your scene size-up and find the scene safe, what is the next phase of patient contact?
- Hospital handoff
- The secondary assessment
- The primary assessment
- Detailed history-taking
Correct answer: The primary assessment
After completing a safe scene size-up, the next phase of patient contact is the primary assessment, where the EMT forms a general impression and identifies and treats immediate life threats to the airway, breathing, and circulation. Scene size-up sets the stage by confirming safety and resources. The secondary assessment, detailed history, and handoff all occur later in the sequence.
- You are dispatched to an assault victim. Police are on scene and report the area is secure, but the assailant has not been located. What is the most appropriate scene-safety mindset during size-up?
- Remain alert because conditions can change, and be ready to retreat
- The scene is permanently safe once police arrive
- Disregard scene safety since police are present
- Begin transport without communicating with police
Correct answer: Remain alert because conditions can change, and be ready to retreat
Remaining alert because conditions can change and being ready to retreat is the correct mindset, since the assailant is still at large. Scene safety is dynamic, and an EMT must continuously reassess even after police arrive. Treating the scene as permanently safe, disregarding safety, or failing to coordinate with police could place the crew in danger.
- You respond to a farm where a worker was injured by machinery that is still running. What must be addressed during scene size-up before patient contact?
- The patient's medication list
- Controlling or shutting down the machinery to make the scene safe
- The patient's blood pressure
- The receiving hospital's specialty
Correct answer: Controlling or shutting down the machinery to make the scene safe
Controlling or shutting down the machinery to make the scene safe must be addressed before patient contact, because running equipment can injure both the patient and the EMT. Scene size-up requires neutralizing mechanical hazards, often with help from trained personnel, before approaching. A medication list, blood pressure, and hospital choice are gathered after the scene is made safe.
- You arrive at the scene of a single-car crash and approach the patient. Before touching the patient, you note that the driver is slumped over the wheel, the windshield is starred, and there is a pool of blood on the floorboard. What part of the primary assessment have you just begun to form?
- The secondary assessment
- The SAMPLE history
- The general impression
- The reassessment
Correct answer: The general impression
Forming the general impression is the first step of the primary assessment. It is the rapid, across-the-room evaluation of the patient's environment, chief complaint, and overall appearance (age, level of distress, position, obvious life threats) that you make before or as you make physical contact. It sets your initial sense of how sick or injured the patient is and guides how aggressively you proceed; the secondary assessment and SAMPLE history come later, and reassessment occurs after interventions.
- You are dispatched to a 58-year-old man with chest pain. According to current EMS education standards, what is the overarching purpose of the primary assessment you perform on first contact?
- To obtain a complete medical history and medication list
- To document a full set of baseline vital signs
- To perform a head-to-toe detailed physical exam
- To identify and treat immediate life threats
Correct answer: To identify and treat immediate life threats
The purpose of the primary assessment is to identify and treat immediate life threats. It is a rapid, systematic evaluation of mental status, airway, breathing, and circulation aimed at finding conditions that will kill the patient in minutes if not corrected. Gathering a full history, a detailed head-to-toe exam, and a complete set of vital signs belong to the history-taking and secondary assessment phases that follow once life threats are managed.
- You are completing the primary assessment on an unresponsive patient. Which sequence best reflects the components of the primary assessment as taught to EMTs?
- Vital signs, SAMPLE history, head-to-toe exam, transport decision
- General impression, level of consciousness, airway, breathing, circulation
- Detailed physical exam, oxygen, splinting, bandaging
- Scene size-up, blood pressure, pupil check, reassessment
Correct answer: General impression, level of consciousness, airway, breathing, circulation
The primary assessment proceeds as general impression, level of consciousness, airway, breathing, and circulation. This ABC-based framework systematically uncovers life threats in the order most likely to kill the patient. Vital signs, the SAMPLE history, and the detailed exam are part of the secondary assessment and history-taking that follow, while scene size-up precedes patient contact.
- You assess an adult who was found down. He does not respond to your voice but groans and withdraws when you pinch his trapezius. Using the AVPU scale, how should you classify his level of responsiveness?
- Painful
- Alert
- Verbal
- Unresponsive
Correct answer: Painful
This patient is classified as Painful (P) on the AVPU scale because he responds only to a painful stimulus, not to voice. AVPU stands for Alert, responds to Verbal stimulus, responds to Painful stimulus, and Unresponsive. A patient who reacts to your spoken voice would be Verbal, and one who shows no reaction at all to pain would be Unresponsive.
- During the primary assessment, an EMT uses the AVPU scale primarily to rapidly evaluate which patient parameter?
- The level of consciousness
- The strength of the pulse
- The adequacy of breathing
- The capillary refill time
Correct answer: The level of consciousness
AVPU is a rapid tool for assessing level of consciousness (mental status) during the primary assessment. It quickly categorizes a patient as Alert, responsive to Verbal stimulus, responsive to Painful stimulus, or Unresponsive. Breathing adequacy, pulse quality, and capillary refill are assessed in the airway, breathing, and circulation steps, not by AVPU.
- You assess an alert patient and want to determine whether she is fully oriented. Which set of questions best establishes that she is 'alert and oriented' during the primary assessment?
- Pulse, respirations, blood pressure, and skin
- Allergies, medications, history, and last meal
- Person, place, time, and event
- Name, address, phone, and birthday
Correct answer: Person, place, time, and event
Determining orientation to person, place, time, and event establishes that an alert patient is fully oriented (often charted as A&Ox4). These four questions test the patient's awareness of who they are, where they are, the current time, and what happened. Allergies, medications, and last meal belong to the SAMPLE history, and vital signs belong to the breathing and circulation assessment.
- You are dispatched to an unresponsive adult who fell from a ladder. You suspect a spinal injury. After establishing unresponsiveness, what is the most appropriate first action to open his airway?
- Insert an oropharyngeal airway immediately
- Jaw-thrust maneuver
- Head-tilt, chin-lift maneuver
- Place him in the recovery position
Correct answer: Jaw-thrust maneuver
The jaw-thrust maneuver is the appropriate first action to open the airway when spinal injury is suspected, because it opens the airway while keeping the cervical spine in a neutral, in-line position. The head-tilt, chin-lift extends the neck and is reserved for patients without suspected spinal trauma. An airway adjunct may follow once the airway is open, and the recovery position would compromise spinal precautions.
- While performing the primary assessment on a trauma patient, the 'X' in the XABC approach directs you to address which life threat first?
- Absent pulse
- Airway obstruction
- Inadequate breathing
- Severe external hemorrhage
Correct answer: Severe external hemorrhage
The 'X' in XABC stands for severe (exsanguinating) external hemorrhage, which is addressed first in the trauma primary assessment. Massive bleeding can kill faster than an airway problem, so current practice prioritizes stopping life-threatening hemorrhage before moving to Airway, Breathing, and Circulation. Once the major bleed is controlled, the EMT continues with the standard ABC sequence.
- You respond to a patient with a partially amputated arm spurting bright red blood, who is also breathing noisily. Applying the XABC priority order, what should you do first?
- Check for a carotid pulse
- Suction the airway
- Begin assisted ventilations
- Apply a tourniquet to control the bleeding
Correct answer: Apply a tourniquet to control the bleeding
Controlling the life-threatening arterial bleed with a tourniquet comes first under the XABC sequence. Spurting bright red blood from a major artery can cause fatal exsanguination within minutes, faster than the noisy airway will harm the patient, so hemorrhage control precedes airway management in trauma. After the bleeding is stopped, you immediately move on to airway and breathing.
- You are assessing an unresponsive patient's breathing during the primary assessment. Which finding indicates inadequate breathing that requires immediate intervention?
- Speaking in full sentences without effort
- Pink, warm, dry skin with clear lung sounds
- A respiratory rate of 6 with shallow, barely visible chest rise
- A respiratory rate of 16 with equal chest rise
Correct answer: A respiratory rate of 6 with shallow, barely visible chest rise
A respiratory rate of 6 with shallow, barely visible chest rise indicates inadequate breathing that requires immediate intervention, typically positive-pressure ventilation. Adequate breathing involves a normal rate (about 12 to 20 in adults) with sufficient depth (tidal volume) and minimal effort. A rate of 16 with equal chest rise, the ability to speak full sentences, and normal skin signs all indicate adequate breathing.
- During the breathing portion of the primary assessment on a conscious adult in respiratory distress, which single finding most strongly signals that you should begin assisting ventilations rather than just giving oxygen?
- Audible wheezing on exhalation
- A respiratory rate of 22 per minute
- An altered mental status with cyanosis and shallow respirations
- Mild accessory muscle use while speaking
Correct answer: An altered mental status with cyanosis and shallow respirations
Altered mental status with cyanosis and shallow respirations signals failing ventilation and the need to assist breathing with a bag-valve mask. These findings show the patient is no longer moving enough air to oxygenate the brain, so simply applying oxygen is insufficient. A rate of 22, isolated wheezing, and mild accessory muscle use indicate distress that may be managed with oxygen and monitoring while you continue assessing.
- You are dispatched to a 24-year-old struck by a car. During the circulation check of your primary assessment, you palpate the pulse. The presence of which pulse confirms adequate circulation to begin assessing pulse quality?
- Any audible heart sound through clothing
- A radial or carotid pulse
- A temporal pulse only
- A pedal (foot) pulse only
Correct answer: A radial or carotid pulse
Palpating a radial or carotid pulse confirms a perfusing heartbeat and lets you assess rate, rhythm, and strength during the circulation step. In an adult, a present radial pulse generally indicates a reasonable systolic pressure, while the carotid is checked if the radial is absent. A pedal pulse alone is unreliable for confirming central perfusion, and heart sounds through clothing are not a substitute for direct pulse palpation.
- While assessing circulation, you press on your patient's nail bed; it blanches white and takes about 4 seconds to return to pink. What does this delayed capillary refill most likely indicate?
- Hyperventilation
- Poor peripheral perfusion
- An adequate blood pressure
- Normal peripheral perfusion
Correct answer: Poor peripheral perfusion
A capillary refill time of about 4 seconds indicates poor peripheral perfusion, since normal refill is 2 seconds or less. Delayed refill suggests reduced blood flow to the extremities, which can be an early sign of shock, especially in children. It does not by itself confirm hyperventilation or an adequate blood pressure; in fact, prolonged refill often accompanies the body's attempt to compensate for inadequate perfusion.
- Capillary refill time is generally considered a more reliable indicator of perfusion in which patient population during the primary assessment?
- Older adults in cold environments
- Patients with peripheral vascular disease
- Patients on beta-blockers
- Young children and infants
Correct answer: Young children and infants
Capillary refill is most reliable in young children and infants, where a refill longer than 2 seconds is a useful early sign of shock. In older adults, cold environments, peripheral vascular disease, and certain medications can all delay refill independent of perfusion, making the test unreliable in those groups. For that reason EMTs weigh capillary refill heavily in pediatric assessment but interpret it cautiously in adults.
- You assess a patient's skin during the circulation check and find it pale, cool, and clammy. These skin signs most directly reflect which physiologic process?
- Dilation of peripheral blood vessels
- An elevated core body temperature
- The body shunting blood from the skin to vital organs
- Increased oxygen saturation in the periphery
Correct answer: The body shunting blood from the skin to vital organs
Pale, cool, and clammy skin reflects the body shunting blood away from the skin toward the core and vital organs, a compensatory response in shock. Peripheral vasoconstriction reduces skin blood flow (causing pallor and coolness) while sympathetic activation produces sweating (clamminess). This is the opposite of vasodilation, and it signals poor perfusion rather than improved peripheral oxygenation.
- What is the best definition of hypoperfusion as used in EMS patient assessment?
- Excess fluid in the lungs
- Inadequate circulation of blood and oxygen to the body's tissues
- An elevated heart rate from exertion
- An abnormally high blood pressure
Correct answer: Inadequate circulation of blood and oxygen to the body's tissues
Hypoperfusion is inadequate circulation of blood and oxygen to the body's tissues and cells, and it is essentially another term for shock. When perfusion fails, cells do not receive enough oxygen and nutrients to function, leading to cellular and eventually organ failure. It is not defined by a single high blood pressure or heart rate value, and it is distinct from pulmonary fluid overload.
- You are dispatched to a patient who fell and has internal bleeding. He is anxious, with a heart rate of 118, pale skin, and a normal blood pressure. Which stage of shock do these findings most closely match?
- Decompensated shock
- Compensated shock
- No shock is present
- Irreversible shock
Correct answer: Compensated shock
These findings match compensated shock, in which the body maintains a normal blood pressure through increased heart rate and peripheral vasoconstriction. Tachycardia, anxiety, and pale skin reflect sympathetic compensation while perfusion to vital organs is still being preserved. Once the blood pressure falls, the patient has progressed to decompensated shock, a much more ominous late stage.
- Which finding best distinguishes decompensated shock from compensated shock during the primary assessment?
- An increased heart rate
- Falling (low) blood pressure
- Anxiety or restlessness
- Pale, cool skin
Correct answer: Falling (low) blood pressure
A falling (low) blood pressure is the hallmark that distinguishes decompensated shock from compensated shock. In compensated shock the body keeps blood pressure normal through tachycardia and vasoconstriction, producing the increased heart rate, pale cool skin, and restlessness seen earlier. When those mechanisms fail and the systolic pressure drops, the patient has decompensated, signaling impending cardiovascular collapse.
- You respond to an injured 6-year-old. Why is a falling blood pressure considered an especially ominous and late sign of shock in pediatric patients?
- Blood pressure cannot be measured accurately in children
- Children rarely develop shock
- Children compensate strongly and maintain blood pressure until they are near collapse
- Children's blood pressure rises rather than falls in shock
Correct answer: Children compensate strongly and maintain blood pressure until they are near collapse
In children, a falling blood pressure is a late, ominous sign because their strong compensatory mechanisms maintain a near-normal pressure until they are close to cardiovascular collapse. Pediatric patients ramp up heart rate and vasoconstriction efficiently, so hypotension appears only after significant volume loss. This is why EMTs rely on earlier signs such as tachycardia, delayed capillary refill, and altered appearance to recognize pediatric shock before the pressure drops.
- During a primary assessment of a patient with suspected internal bleeding, which group of findings represents the early signs and symptoms of shock?
- Slow strong pulse, warm flushed skin, and bradypnea
- Normal mentation, pink skin, and a slow regular pulse
- Restlessness, rapid weak pulse, pale cool clammy skin, and thirst
- Hypertension, dry mouth, and flushed face
Correct answer: Restlessness, rapid weak pulse, pale cool clammy skin, and thirst
Restlessness, a rapid weak pulse, pale cool clammy skin, and thirst are the classic early signs and symptoms of shock. They result from sympathetic compensation: the heart speeds up, vessels in the skin constrict, and the patient feels anxious and thirsty as the body tries to preserve perfusion. A slow strong pulse, warm flushed skin, and normal mentation are not consistent with developing hypoperfusion.
- You are assessing an unconscious trauma patient. The patient does not open his eyes, makes incomprehensible sounds, and withdraws from pain. To calculate his Glasgow Coma Scale score, what three response categories do you add together?
- Eye opening, verbal response, and motor response
- Airway, breathing, and circulation
- Pulse, respirations, and blood pressure
- Alertness, orientation, and pupil size
Correct answer: Eye opening, verbal response, and motor response
The Glasgow Coma Scale is calculated by adding the scores for eye opening, verbal response, and motor response. Eye opening is scored 1 to 4, verbal response 1 to 5, and motor response 1 to 6. The sum ranges from 3 (no response in any category) to 15 (fully responsive), and it is unrelated to vital signs, pupil size, or the ABC sequence.
- You assess a head-injured patient who opens his eyes only to a painful stimulus (2), makes incomprehensible sounds (2), and withdraws from pain (4). What is his total Glasgow Coma Scale score?
Correct answer: 8
The total Glasgow Coma Scale score is 8: eye opening to pain (2) plus incomprehensible sounds (2) plus withdrawal from pain (4) equals 8. The GCS is the simple sum of the best eye, verbal, and motor responses. A score of 8 or less is often used as a threshold indicating a significantly decreased level of consciousness and a possible need for advanced airway management.
- What is the lowest possible total score on the Glasgow Coma Scale, and what does it represent?
- 1, representing deep coma
- 3, representing no eye, verbal, or motor response
- 0, representing brain death
- 8, representing a comatose patient
Correct answer: 3, representing no eye, verbal, or motor response
The lowest possible Glasgow Coma Scale score is 3, which represents no eye opening, no verbal response, and no motor response. Because each of the three categories has a minimum score of 1, the totals can never fall below 3 even in a completely unresponsive patient. A score of 8 indicates coma but is not the minimum, and the GCS does not use 0 or 1 as a total.
- A patient with a head injury has a Glasgow Coma Scale total of 7. How should an EMT interpret this score?
- A mildly altered patient who is fully oriented
- A severely decreased level of consciousness consistent with coma
- An indication the patient is malingering
- A normal level of consciousness
Correct answer: A severely decreased level of consciousness consistent with coma
A Glasgow Coma Scale total of 7 indicates a severely decreased level of consciousness consistent with coma, since scores of 8 or below generally define coma. Such a patient cannot reliably protect his own airway and needs close monitoring of airway and breathing during the primary assessment. A normal GCS is 15, so a score of 7 is clearly abnormal and reflects a genuine, serious deficit.
- An EMT is choosing between the AVPU scale and the Glasgow Coma Scale during a rapid primary assessment. Which statement best describes the difference between the two tools?
- AVPU is a quick four-category mental status check, while the GCS is a more detailed numeric score
- The GCS is faster and simpler than AVPU
- AVPU can only be used on children and the GCS only on adults
- AVPU measures breathing, while the GCS measures circulation
Correct answer: AVPU is a quick four-category mental status check, while the GCS is a more detailed numeric score
AVPU is a quick four-category mental status check (Alert, Verbal, Painful, Unresponsive), while the Glasgow Coma Scale is a more detailed numeric score from 3 to 15. EMTs often use AVPU for a rapid initial impression and the GCS for a more precise, trendable measure of consciousness. Both assess mental status rather than breathing or circulation, and both can be applied across age groups.
- You are dispatched to a 'sick person.' On arrival the patient states, 'I can't catch my breath.' During the primary assessment, this statement is best categorized as the patient's:
- Baseline vital sign
- Past medical history
- Mechanism of injury
- Chief complaint
Correct answer: Chief complaint
The patient's statement 'I can't catch my breath' is the chief complaint, the primary reason in the patient's own words that EMS was called. The chief complaint helps focus the assessment and directs which life threats to evaluate first. It is distinct from past medical history, mechanism of injury (relevant to trauma), and vital signs, all of which are gathered separately.
- When an EMT documents a patient's chief complaint, the entry should ideally reflect:
- The most serious injury found on the exam
- The dispatch code assigned by the call center
- The EMT's working diagnosis
- The patient's complaint in his or her own words
Correct answer: The patient's complaint in his or her own words
The chief complaint should reflect the patient's complaint in his or her own words, such as 'chest pressure' or 'I feel dizzy.' Capturing the patient's actual words avoids prematurely committing to a diagnosis and preserves an accurate picture of why help was requested. The EMT's working impression, the dispatch code, and the most serious finding are documented separately and are not the chief complaint.
- You are dispatched to an unresponsive diabetic. After confirming the scene is safe, what is the first patient-contact action of your primary assessment?
- Begin a head-to-toe exam
- Measure the blood pressure
- Take a blood glucose reading
- Assess responsiveness and form a general impression
Correct answer: Assess responsiveness and form a general impression
The first patient-contact action is to assess responsiveness and form a general impression. You determine whether the patient reacts to you (using AVPU) and gather your overall sense of how sick the patient appears before proceeding to airway, breathing, and circulation. Blood glucose, blood pressure, and the detailed head-to-toe exam come after life threats have been addressed.
- During the primary assessment of an unresponsive patient, you hear gurgling with each breath. What does this finding indicate, and what is your immediate action?
- Bronchospasm; give an inhaler
- Normal airway; continue assessment
- Adequate breathing; apply a nasal cannula
- Fluid in the airway; suction immediately
Correct answer: Fluid in the airway; suction immediately
Gurgling indicates fluid such as blood, vomit, or secretions in the airway, and the immediate action is to suction. An unprotected, fluid-filled airway in an unresponsive patient is an immediate life threat because of the risk of aspiration. Gurgling is not a normal sound, is not caused by bronchospasm, and must be cleared before continuing the assessment or applying oxygen.
- While performing the primary assessment on an unresponsive patient, you hear snoring respirations. What is the most likely cause and the appropriate corrective action?
- Tension pneumothorax; perform needle decompression
- The tongue partially obstructing the airway; reposition the airway or insert an adjunct
- Lower airway fluid; administer a bronchodilator
- Normal sleep; allow the patient to rest
Correct answer: The tongue partially obstructing the airway; reposition the airway or insert an adjunct
Snoring respirations in an unresponsive patient are typically caused by the tongue falling back and partially obstructing the upper airway; the correction is to reposition the airway with a head-tilt or jaw-thrust and consider an airway adjunct. This is a common, rapidly correctable life threat found during the airway step. It is not caused by lower airway fluid or a pneumothorax, and it should never be dismissed as normal sleep.
- You are assessing breathing on a patient with a stab wound to the chest and hear air being sucked into the wound on inhalation. Which immediate life threat have you identified during the primary assessment?
- An open (sucking) chest wound
- Hyperventilation syndrome
- A normal breath sound
- A simple bruise
Correct answer: An open (sucking) chest wound
Air moving in and out of a chest wound identifies an open (sucking) chest wound, an immediate life threat found during the breathing step of the primary assessment. Air entering the pleural space through the wound can collapse the lung and impair ventilation, so it must be sealed promptly. This is far more serious than a bruise or hyperventilation and is never a normal finding.
- You assess an adult's circulation and find the radial pulse is absent but the carotid pulse is present. What does this finding suggest about the patient's condition?
- Possible low blood pressure or shock
- Excellent peripheral circulation
- Normal perfusion
- An irregular but healthy heart rhythm
Correct answer: Possible low blood pressure or shock
An absent radial pulse with a present carotid pulse suggests a low blood pressure consistent with shock. As perfusion pressure drops, distal pulses such as the radial fade before central pulses such as the carotid. This pattern is a warning sign during the circulation step that the patient may be decompensating and needs rapid intervention and transport.
- You are dispatched to a 70-year-old woman who 'doesn't look right.' Forming your general impression, you note she is sitting upright, leaning forward on her hands, and struggling to speak. This positioning during the general impression most strongly suggests:
- Mild dehydration
- A psychiatric emergency
- A minor musculoskeletal injury
- Severe respiratory distress
Correct answer: Severe respiratory distress
A patient sitting upright and leaning forward on the hands (the tripod position) who is struggling to speak strongly suggests severe respiratory distress. This posture maximizes the use of accessory breathing muscles, and the inability to speak in full sentences signals a serious airway or breathing problem identified in the general impression. It is not characteristic of mild dehydration, a psychiatric emergency, or a minor musculoskeletal injury.
- During the primary assessment, which of the following is considered the single most important indicator of a patient's overall status and the first thing assessed after forming a general impression?
- Skin color
- Mental status (level of consciousness)
- Body temperature
- Pupil reactivity
Correct answer: Mental status (level of consciousness)
Mental status, or level of consciousness, is the most important early indicator of overall status and is assessed immediately after the general impression. A change in mental status often reflects inadequate oxygenation or perfusion of the brain and is one of the earliest signs of a serious problem. Skin color, pupil reactivity, and temperature provide useful information but do not outweigh the patient's level of consciousness as a status indicator.
- You are caring for a responsive adult who is talking to you in full, clear sentences. What does this single observation immediately confirm about his primary assessment?
- He has no internal bleeding
- His airway is open and he is moving adequate air
- He has a normal blood pressure
- His blood glucose is normal
Correct answer: His airway is open and he is moving adequate air
A patient speaking in full, clear sentences confirms that his airway is open (patent) and that he is moving enough air to phonate. Speech requires both an unobstructed airway and adequate breathing, so this quickly clears the A and supports the B of the primary assessment. It does not, however, confirm a normal blood pressure, glucose level, or the absence of internal bleeding, which require further assessment.
- You are assessing breathing on a patient and need to judge whether ventilation is adequate. Which three characteristics should you evaluate?
- Rate, rhythm, and blood pressure
- Rate, depth (tidal volume), and effort
- Pupil size, gaze, and reactivity
- Color, temperature, and moisture
Correct answer: Rate, depth (tidal volume), and effort
Adequate breathing is judged by rate, depth (tidal volume), and effort. A patient may have a normal rate but inadequate depth, or may be breathing fast with excessive effort, both of which indicate respiratory compromise. Skin signs and pupils are assessed elsewhere, and blood pressure is part of circulation rather than the breathing evaluation.
- You are dispatched to a major motor vehicle collision. As you reach the patient, what is the correct relationship between scene size-up and the primary assessment?
- The primary assessment replaces scene size-up
- Scene size-up is completed before beginning the patient's primary assessment
- The primary assessment is done before the scene is evaluated
- Scene size-up and the detailed exam occur at the same time
Correct answer: Scene size-up is completed before beginning the patient's primary assessment
Scene size-up is completed before beginning the patient's primary assessment. Evaluating scene safety, the number of patients, the mechanism of injury, and the need for additional resources protects the crew and shapes how the assessment proceeds. Only after the scene is judged safe to enter does the EMT make patient contact and begin the primary assessment.
- During the circulation portion of the primary assessment on a bleeding patient, what is the priority action when you discover severe external hemorrhage?
- Complete the SAMPLE history
- Record an accurate blood pressure first
- Splint any associated fractures
- Apply direct pressure or a tourniquet to control the bleeding
Correct answer: Apply direct pressure or a tourniquet to control the bleeding
The priority when severe external hemorrhage is found is to control it immediately with direct pressure or a tourniquet. Uncontrolled major bleeding is an immediate life threat that must be stopped during the circulation step before moving on. Obtaining a blood pressure, completing the SAMPLE history, and splinting fractures are all lower priorities that follow control of life-threatening hemorrhage.
- You assess a child who is quiet, limp, and makes poor eye contact. In the primary assessment, why is this abnormal appearance so significant?
- It is a normal finding in frightened children
- It reflects only the child's mood and can be ignored
- It indicates the child is simply tired
- It can be an early indicator of inadequate brain perfusion or oxygenation
Correct answer: It can be an early indicator of inadequate brain perfusion or oxygenation
A quiet, limp child with poor eye contact is significant because an abnormal appearance can be an early indicator of inadequate brain perfusion or oxygenation. Children typically interact, resist, and make eye contact, so a dull, listless appearance suggests a serious underlying problem even before vital signs change. This abnormal mental status should never be dismissed as mood or tiredness during the primary assessment.
- You determine a trauma patient has a life threat during the primary assessment and classify him as a high-priority transport. What is the EMS term for this rapid identification of a critically injured patient?
- Obtaining medical history
- Identifying a 'load-and-go' or priority patient
- Performing a detailed physical exam
- Conducting reassessment
Correct answer: Identifying a 'load-and-go' or priority patient
Rapidly recognizing a critically ill or injured patient during the primary assessment is known as identifying a 'load-and-go' or high-priority patient. The goal is to spend minimal time on scene and expedite transport to definitive care once a life threat is found. This is distinct from the detailed physical exam, reassessment, and history gathering, which either follow or occur en route for these patients.
- You assess a patient's breathing and find a respiratory rate of 30, shallow chest rise, and the patient using neck muscles to breathe. How should you classify this breathing?
- Normal breathing for an adult
- Inadequate breathing requiring intervention
- Adequate breathing
- Slow breathing requiring no action
Correct answer: Inadequate breathing requiring intervention
A rate of 30 with shallow chest rise and accessory neck-muscle use is inadequate breathing that requires intervention such as high-flow oxygen and possible assisted ventilation. Although the rate is fast, the shallow depth means minimal air is actually being exchanged, and the use of accessory muscles signals increased work of breathing. This pattern is neither adequate nor normal and should not be left untreated.
- While forming your general impression of a patient, which three broad elements should you quickly take in?
- Allergies, medications, and last oral intake
- Pupils, grip strength, and gait
- Blood pressure, pulse, and temperature
- Appearance, work of breathing, and circulation to the skin
Correct answer: Appearance, work of breathing, and circulation to the skin
A useful general impression rapidly takes in the patient's appearance, work of breathing, and circulation to the skin, the three components of the pediatric assessment triangle that work well for all ages. These observable elements give an immediate sense of how sick the patient is before hands-on assessment. Allergies and last intake belong to the SAMPLE history, while specific vital signs and focused neurologic tests come later.
- You are dispatched to an unresponsive overdose patient who is breathing only 4 times per minute. In the primary assessment, after ensuring the airway is open, what is the most appropriate breathing intervention?
- Provide positive-pressure ventilation with a bag-valve mask
- Encourage the patient to take deep breaths
- Apply a nasal cannula at 2 liters per minute
- Place the patient in the recovery position and observe
Correct answer: Provide positive-pressure ventilation with a bag-valve mask
With a respiratory rate of only 4 breaths per minute, the patient is not moving adequate air, so the appropriate intervention is positive-pressure ventilation with a bag-valve mask and supplemental oxygen. This dangerously slow rate cannot sustain oxygenation, and a nasal cannula provides far too little support. Encouraging deep breaths is futile in an unresponsive patient, and simply observing would allow respiratory and then cardiac arrest.
- A patient in shock has progressed to confusion, a barely palpable pulse, and a systolic blood pressure of 70. The transition from compensated to decompensated shock is best explained by which physiologic change?
- Peripheral vessels have fully dilated to improve flow
- The patient's blood volume has suddenly increased
- The heart rate has dropped to a normal resting value
- The body's compensatory mechanisms have failed to maintain blood pressure
Correct answer: The body's compensatory mechanisms have failed to maintain blood pressure
The progression to confusion, a thready pulse, and a systolic pressure of 70 reflects the failure of the body's compensatory mechanisms to maintain blood pressure, defining decompensated shock. Earlier, tachycardia and vasoconstriction kept the pressure normal, but once those mechanisms are exhausted the pressure falls and brain perfusion drops, producing confusion. This is not caused by increased blood volume, beneficial vasodilation, or a normalizing heart rate.
- You are caring for a head-injured patient and want to trend his level of consciousness over time as you transport. Why is the Glasgow Coma Scale particularly useful to an EMT for this purpose?
- It directly measures the patient's blood pressure
- It eliminates the need to assess the airway
- It replaces the need to monitor breathing
- It provides a reproducible numeric score that can be compared between repeated assessments
Correct answer: It provides a reproducible numeric score that can be compared between repeated assessments
The Glasgow Coma Scale is useful for trending because it produces a reproducible numeric score (3 to 15) that different providers can compare across repeated assessments to detect improvement or deterioration. A dropping GCS over time alerts the EMT to a worsening brain injury and the need to protect the airway. It does not measure blood pressure and never replaces ongoing airway and breathing assessment.
- You are dispatched to a residence for a 58-year-old man with chest discomfort. As you enter the room and before touching the patient, you note he is sitting upright, leaning forward on his hands, pale, sweating, and speaking in short phrases. Which part of the primary assessment are you performing at this moment?
- Reassessing interventions
- Obtaining baseline vital signs
- Performing a focused secondary assessment
- Forming a general impression
Correct answer: Forming a general impression
Forming a general impression is the correct answer. The general impression is the immediate, across-the-room evaluation of the patient's appearance, work of breathing, and skin that you form within seconds of arriving, before any hands-on assessment. It tells you whether the patient looks sick or not sick and how urgently you must act. Baseline vital signs and a focused secondary assessment come later, after life threats are addressed.
- The primary assessment of every patient is performed for one overriding purpose. Which of the following best describes that purpose?
- To obtain a complete past medical history
- To identify and immediately treat any immediate threats to life
- To determine the patient's insurance and destination preference
- To document the call accurately for billing
Correct answer: To identify and immediately treat any immediate threats to life
Identifying and immediately treating immediate threats to life is the purpose of the primary assessment. It is a rapid, systematic check of mental status, airway, breathing, and circulation designed to find conditions that will kill the patient in minutes so they can be corrected before moving on. Gathering a full history and detailed exam belong to the secondary assessment, which happens only after life threats are managed.
- You approach an unresponsive-appearing patient slumped in a chair. You tap his shoulders and shout, and he opens his eyes and mumbles. Using the AVPU scale, how should you classify his level of responsiveness?
- Responsive to verbal stimulus
- Responsive to painful stimulus
- Unresponsive
- Alert
Correct answer: Responsive to verbal stimulus
Responsive to verbal stimulus (the V in AVPU) is correct because the patient responded only after you spoke loudly to him, not spontaneously. AVPU classifies a patient as Alert (awake and interacting without stimulation), Verbal (responds to voice), Painful (responds only to a painful stimulus), or Unresponsive (no response). Because he required a verbal stimulus to respond, he is graded V, not A.
- During the primary assessment, what does the letter P stand for in the AVPU scale used to rapidly gauge level of consciousness?
- Patient is pediatric
- Pupils equal
- Responds to painful stimulus
- Pulse present
Correct answer: Responds to painful stimulus
Responds to painful stimulus is what P stands for in AVPU. The AVPU scale grades a patient as Alert, Verbal, Painful, or Unresponsive, and the P level means the patient does not react to voice but does react to a painful stimulus such as a trapezius pinch. It is a fast mental-status tool, not a measure of pulse or pupils.
- You are assessing a patient's circulation during the primary assessment. You press on the patient's nail bed, release, and time how long the color takes to return. What are you measuring and what is the normal value in a healthy adult?
- Capillary refill, normally less than 2 seconds
- Capillary refill, normally 5 to 6 seconds
- Pulse pressure, normally less than 2 seconds
- Oxygen saturation, normally above 94 percent
Correct answer: Capillary refill, normally less than 2 seconds
Capillary refill, normally less than 2 seconds, is what this maneuver measures. Pressing the nail bed blanches it; when released, color should return in under 2 seconds in a well-perfused adult. Delayed refill suggests poor peripheral perfusion and possible shock. It is a circulation check, not a measure of pulse pressure or oxygen saturation.
- You are dispatched to a 24-year-old who fell from a roof and is unresponsive with obvious bleeding. Using the XABC approach to the primary assessment, what should you address first?
- Control of life-threatening (exsanguinating) hemorrhage
- Breathing adequacy
- Circulation and pulse check
- Airway patency
Correct answer: Control of life-threatening (exsanguinating) hemorrhage
Control of life-threatening hemorrhage is addressed first in the XABC approach. The X stands for exsanguinating hemorrhage and is placed ahead of Airway, Breathing, and Circulation because a patient can bleed to death faster than an airway or breathing problem will kill them. After massive external bleeding is controlled, you proceed to airway, breathing, and circulation.
- In the traditional ABC sequence of the primary assessment, what do the letters A, B, and C represent in order?
- Airway, Breathing, Circulation
- Assessment, Bleeding, Consciousness
- Alert, Breathing, Circulation
- Airway, Bleeding, Cardiac
Correct answer: Airway, Breathing, Circulation
Airway, Breathing, Circulation is what A, B, and C represent. After checking mental status, the EMT ensures the airway is open, evaluates whether breathing is adequate, and then assesses circulation including pulse, skin, and major bleeding. This ordered sequence ensures the most rapidly fatal problems are found and corrected first.
- You are dispatched to a 70-year-old woman who is confused. Her family asks why she is being checked so quickly. The chief complaint in the primary assessment is best defined as which of the following?
- The most serious abnormal vital sign found
- The EMT's working diagnosis of the patient's condition
- The reason EMS was called, stated in the patient's or bystander's own words
- The list of the patient's prescribed medications
Correct answer: The reason EMS was called, stated in the patient's or bystander's own words
The reason EMS was called, stated in the patient's or bystander's own words, is the chief complaint. It is the primary problem the patient or those around them identify, such as trouble breathing or chest pain, and it focuses the assessment. It is not the EMT's diagnosis, a vital sign, or a medication list, all of which are gathered or formed separately.
- You respond to a 30-year-old struck by a car. He is unresponsive. As you assess his airway, you hear a snoring sound with each breath. What does this finding most likely indicate, and what is your immediate action?
- Adequate breathing; apply a nasal cannula
- Partial airway obstruction from the tongue; open the airway with a manual maneuver
- Tension pneumothorax; prepare for transport
- A clear airway; continue assessment
Correct answer: Partial airway obstruction from the tongue; open the airway with a manual maneuver
Partial airway obstruction from the tongue, managed by opening the airway with a manual maneuver, is correct. Snoring respirations in an unresponsive patient typically mean the tongue has fallen back and is partially blocking the airway. The immediate action is a head-tilt chin-lift, or a jaw-thrust if trauma is suspected, often followed by an airway adjunct. Snoring is never a sign of a clear airway.
- You are assessing breathing on a responsive adult during the primary assessment. Which combination of findings would most concern you for inadequate breathing requiring immediate ventilatory support?
- Rate of 14, equal breath sounds, normal mentation
- Rate of 16, full chest rise, pink skin
- Rate of 18, speaking full sentences, warm skin
- Rate of 6, shallow chest movement, cyanosis around the lips
Correct answer: Rate of 6, shallow chest movement, cyanosis around the lips
A rate of 6 with shallow chest movement and cyanosis around the lips signals inadequate breathing requiring immediate ventilation. Adequate breathing involves a normal rate (roughly 12 to 20 in an adult), adequate depth (good chest rise), and adequate oxygenation (pink skin). A slow, shallow pattern with cyanosis means minute ventilation is too low, and the EMT must assist ventilations with a bag-valve mask.
- You are dispatched to a 45-year-old man involved in a high-speed crash. He is anxious, his skin is pale, cool, and clammy, his pulse is 120 and weak, but his blood pressure remains 118/76. How would you classify this stage of shock?
- Compensated shock
- Decompensated shock
- No shock is present because blood pressure is normal
- Irreversible shock
Correct answer: Compensated shock
Compensated shock is correct because the body is still maintaining a normal blood pressure through increased heart rate and vasoconstriction, which produces the pale, cool, clammy skin and rapid weak pulse. In compensated shock the systolic pressure has not yet dropped. A falling blood pressure marks the transition to decompensated shock, a late and ominous finding.
- You are caring for a 60-year-old with massive gastrointestinal bleeding. Over a few minutes she becomes lethargic, her skin is mottled, and her blood pressure drops from 110/70 to 78/50. This change indicates the patient has progressed to which stage of shock?
- Psychogenic shock
- Decompensated shock
- Early shock with intact compensation
- Compensated shock
Correct answer: Decompensated shock
Decompensated shock is correct because the falling blood pressure shows that the body's compensatory mechanisms (vasoconstriction and increased heart rate) can no longer maintain perfusion. The hallmark distinguishing decompensated from compensated shock is hypotension. Decompensated shock is a late, life-threatening stage requiring rapid transport and aggressive treatment.
- A patient you are assessing is in shock. The underlying problem in all forms of shock is best described by which term?
- An elevated blood glucose level
- Hypoperfusion, meaning inadequate delivery of oxygenated blood to the tissues
- Hyperperfusion of the brain
- Excessive oxygen in the bloodstream
Correct answer: Hypoperfusion, meaning inadequate delivery of oxygenated blood to the tissues
Hypoperfusion, meaning inadequate delivery of oxygenated blood to the tissues, defines shock. Regardless of the cause, shock is a state in which cells do not receive enough oxygen and nutrients to function, leading to cellular and organ dysfunction. Recognizing hypoperfusion early in the primary assessment allows the EMT to intervene before it becomes irreversible.
- You are calculating a Glasgow Coma Scale score on a head-injured patient. What are the three components that are summed to produce the total score?
- Pulse, blood pressure, and respiratory rate
- Eye opening, verbal response, and motor response
- Pupil size, skin color, and capillary refill
- Airway, breathing, and circulation
Correct answer: Eye opening, verbal response, and motor response
Eye opening, verbal response, and motor response are the three components of the Glasgow Coma Scale. Each is scored separately and the values are added together to give a total ranging from 3 to 15. The GCS is a structured, reproducible measure of level of consciousness, more detailed than the rapid AVPU scale.
- You assess a patient using the Glasgow Coma Scale. What are the minimum and maximum possible total GCS scores?
- Minimum 1 and maximum 12
- Minimum 0 and maximum 10
- Minimum 3 and maximum 15
- Minimum 5 and maximum 20
Correct answer: Minimum 3 and maximum 15
A minimum of 3 and a maximum of 15 are the bounds of the Glasgow Coma Scale. Eye opening is scored 1 to 4, verbal response 1 to 5, and motor response 1 to 6, so even a completely unresponsive patient scores 3 (one point per category) and a fully normal patient scores 15. A score cannot be zero because the lowest value in each category is 1.
- You are assessing a trauma patient and find a total Glasgow Coma Scale score of 7. Based on standard interpretation, what does this score indicate?
- Severe brain injury or coma
- Normal neurologic status
- Malingering
- Mild brain injury
Correct answer: Severe brain injury or coma
Severe brain injury or coma is indicated by a GCS of 7. Scores of 13 to 15 reflect mild injury, 9 to 12 moderate injury, and 8 or below severe injury with significant impairment of consciousness. A patient scoring 8 or less generally cannot protect their own airway, so this finding directs urgent airway management and rapid transport.
- You arrive to find a 19-year-old who collapsed at a party and is unresponsive. After confirming the scene is safe, what is the most appropriate first action of your primary assessment?
- Obtain a full set of vital signs
- Gather a SAMPLE history from bystanders
- Check for responsiveness and assess the airway and breathing
- Apply a cardiac monitor and obtain a 12-lead
Correct answer: Check for responsiveness and assess the airway and breathing
Checking for responsiveness and assessing the airway and breathing is the correct first action. The primary assessment begins with level of consciousness, then immediately moves to airway and breathing because these are the most rapidly fatal problems. Full vital signs, cardiac monitoring, and history-taking are valuable but follow once immediate life threats have been addressed.
- You are assessing circulation on an unresponsive adult during the primary assessment. Where should you palpate for a pulse, and what does its absence require?
- The brachial pulse; if absent, obtain a blood pressure
- The carotid pulse; if absent, begin CPR
- The pedal pulse; if absent, elevate the legs
- The radial pulse; if absent, apply oxygen
Correct answer: The carotid pulse; if absent, begin CPR
Palpating the carotid pulse, and beginning CPR if it is absent, is correct for an unresponsive adult. The carotid is a central pulse that remains palpable even when peripheral pulses are lost due to poor perfusion. If no pulse is felt within 10 seconds in an unresponsive patient, the EMT must start chest compressions immediately.
- You are dispatched for a diabetic emergency. The patient is responsive but only opens her eyes and moans when you firmly squeeze her trapezius muscle. Where does she fall on the AVPU scale?
- Unresponsive
- Alert
- Painful
- Verbal
Correct answer: Painful
Painful is correct because she responds only to a painful stimulus (the trapezius squeeze) and not to voice. On the AVPU scale, a patient who does not react when spoken to but does react to pain is graded P. This level of consciousness is concerning because the patient may not be able to protect her airway and warrants close monitoring.
- You are forming a general impression of a 4-year-old as you enter the room. The child is limp, makes no eye contact, and does not react to your approach. What does this general impression most strongly suggest?
- A critically ill or unstable child requiring immediate intervention
- A child with a minor isolated extremity injury
- A well-appearing child who can wait for assessment
- A child who is simply shy around strangers
Correct answer: A critically ill or unstable child requiring immediate intervention
A critically ill or unstable child requiring immediate intervention is the correct interpretation. A limp child who does not make eye contact or react to a stranger's approach shows abnormal appearance and poor interactivity, which are red flags in the across-the-room general impression. This drives an urgent, hands-on primary assessment rather than a relaxed approach.
- You are caring for a 50-year-old with severe sepsis whose skin is warm and flushed rather than cool and pale, yet he is clearly hypoperfused. Why can a shock patient sometimes present with warm skin?
- In distributive shock, widespread vasodilation can leave the skin warm despite poor tissue perfusion
- Skin temperature has no relationship to perfusion
- Warm skin proves the patient is not actually in shock
- Warm skin only occurs in cardiogenic shock
Correct answer: In distributive shock, widespread vasodilation can leave the skin warm despite poor tissue perfusion
In distributive shock, widespread vasodilation can leave the skin warm despite poor tissue perfusion, which explains the warm flushed presentation. In hypovolemic and cardiogenic shock the body vasoconstricts, producing cool clammy skin, but in septic, anaphylactic, and neurogenic shock blood vessels dilate, so the skin may feel warm even though the tissues are still hypoperfused.
- You are assessing a patient's airway during the primary assessment. The patient is awake, speaking clearly in full sentences, and has no abnormal airway sounds. What does this tell you about the airway?
- The airway is obstructed and requires suctioning
- The airway is currently patent and self-maintained
- The patient needs immediate intubation
- An oropharyngeal airway must be inserted immediately
Correct answer: The airway is currently patent and self-maintained
The airway is currently patent and self-maintained is the correct conclusion. A patient who is alert and speaking clearly in full sentences is moving air well and protecting their own airway, so no airway adjunct is needed at this moment. Inserting an oropharyngeal airway in a conscious patient is contraindicated because it would trigger the gag reflex.
- You assess an unresponsive trauma patient's GCS. He does not open his eyes (eye score 1), makes incomprehensible sounds (verbal score 2), and withdraws from pain (motor score 4). What is his total GCS score?
Correct answer: 7
A total GCS of 7 is correct: eye opening 1 plus verbal response 2 plus motor response 4 equals 7. Summing the three component scores is how the Glasgow Coma Scale is calculated. A score of 7 falls in the severe range (8 or below), signaling a depressed level of consciousness and the likely need for aggressive airway management.
- During the primary assessment of a responsive medical patient, when should the EMT identify the chief complaint?
- Never; the chief complaint is documented by the hospital
- Only after a complete head-to-toe exam
- Only if the patient is unresponsive
- Early, as part of determining the reason for the call and guiding the assessment
Correct answer: Early, as part of determining the reason for the call and guiding the assessment
Identifying the chief complaint early, as part of determining the reason for the call and guiding the assessment, is correct. The chief complaint is established near the start of patient contact and steers the rest of the evaluation toward the patient's main problem. Waiting until after a full exam would delay focused care and is not how the primary assessment is structured.
- You are assessing a 35-year-old who was stabbed in the thigh with bright red blood spurting from the wound. Applying the XABC concept of the primary assessment, what is your immediate priority?
- Check the radial pulse and skin color
- Apply direct pressure or a tourniquet to control the hemorrhage
- Begin positive pressure ventilation
- Open the airway with a jaw-thrust
Correct answer: Apply direct pressure or a tourniquet to control the hemorrhage
Applying direct pressure or a tourniquet to control the hemorrhage is the immediate priority. In the XABC framework, the X (exsanguinating hemorrhage) comes before airway and breathing because spurting bright red arterial bleeding can cause death within minutes. Once the life-threatening bleed is controlled, the EMT proceeds to airway, breathing, and circulation.
- You complete a primary assessment on a 65-year-old with sudden weakness, slurred speech, and a facial droop. His airway is patent and breathing is adequate. Based on the primary assessment, what is your most appropriate decision?
- Identify the patient as high priority and arrange rapid transport
- Treat the call as low priority and downgrade your response
- Release the patient because the airway is clear
- Delay transport to complete a full set of repeat vitals first
Correct answer: Identify the patient as high priority and arrange rapid transport
Identifying the patient as high priority and arranging rapid transport is correct. A key endpoint of the primary assessment is deciding whether the patient needs rapid treatment, rapid transport, or additional resources. Sudden weakness, slurred speech, and facial droop suggest stroke, a time-critical emergency, so the patient is high priority even though the airway and breathing are currently adequate.
- You are assessing skin as a circulation indicator during the primary assessment. Which skin finding is the most concerning sign of poor perfusion in an adult?
- Slightly flushed cheeks after exercise
- Cool, pale, diaphoretic skin
- Normal skin turgor
- Warm, pink, dry skin
Correct answer: Cool, pale, diaphoretic skin
Cool, pale, diaphoretic skin is the most concerning sign of poor perfusion. When perfusion drops, the body shunts blood away from the skin to vital organs and activates a sympathetic stress response, producing cool, pale, sweaty skin. Warm, pink, dry skin and normal turgor reflect adequate perfusion, and post-exercise flushing is a benign finding.
- You are assessing an unresponsive overdose patient to determine level of consciousness quickly. Which sequence correctly describes how to assess level of consciousness using AVPU?
- First obtain a GCS, then convert it to AVPU
- First apply a painful stimulus, then check if the patient is alert
- First check pupils, then pulse, then blood pressure
- First see if the patient is alert, then add a verbal stimulus, then a painful stimulus if needed
Correct answer: First see if the patient is alert, then add a verbal stimulus, then a painful stimulus if needed
First see if the patient is alert, then add a verbal stimulus, then a painful stimulus if needed is the correct sequence for assessing level of consciousness with AVPU. You begin by observing whether the patient is spontaneously awake and interacting; if not, you speak to them, and only if there is still no response do you apply a painful stimulus. The patient is graded at the first level that elicits a response.
- You are dispatched to a 58-year-old man with crushing chest pain. He has a current prescription for nitroglycerin and a systolic blood pressure of 92 mmHg. Before assisting with his nitroglycerin, which finding is an absolute contraindication to giving the dose?
- A systolic blood pressure below 100 mmHg
- Pain that radiates to the left arm
- A heart rate of 96 beats per minute
- A respiratory rate of 20 breaths per minute
Correct answer: A systolic blood pressure below 100 mmHg
A systolic blood pressure below 100 mmHg is a contraindication to nitroglycerin. Nitroglycerin is a vasodilator that lowers blood pressure, so giving it to an already hypotensive patient can cause dangerous hypotension and reduced coronary perfusion. A heart rate of 96, arm radiation, and a normal respiratory rate are not contraindications. Other contraindications include recent erectile-dysfunction drug use (such as sildenafil within 24 to 48 hours) and suspected right ventricular infarction.
- You are dispatched to a 64-year-old woman with chest pressure and shortness of breath that began 30 minutes ago. She has no allergies and is not taking blood thinners. After applying oxygen, which medication and dose is within EMT scope for suspected acute coronary syndrome?
- Aspirin 81 mg, swallowed whole
- Aspirin 324 mg, chewed
- Aspirin 650 mg, swallowed whole
- Aspirin 162 mg, dissolved under the tongue
Correct answer: Aspirin 324 mg, chewed
Aspirin 324 mg, chewed, is the standard EMT dose for suspected acute coronary syndrome, typically given as four 81 mg chewable baby aspirin. Chewing speeds absorption so the antiplatelet effect begins sooner. The 81 mg, 650 mg, and sublingual options are incorrect doses or routes for this indication. Aspirin is withheld if the patient is allergic or has signs of active GI bleeding.
- You are dispatched to a 30-year-old man found unresponsive next to drug paraphernalia. His respirations are 4 per minute and shallow with pinpoint pupils. After beginning bag-valve-mask ventilation, what is the correct initial intranasal naloxone dose for an EMT?
- 10 mg intranasally
- 0.4 mg intranasally
- 4 mg intranasally
- 1 mg intranasally
Correct answer: 4 mg intranasally
4 mg intranasally is the standard initial naloxone dose for EMTs using the commercial intranasal device, often given as one full spray in a single nostril. Naloxone reverses opioid-induced respiratory depression, but ventilation with the bag-valve mask comes first because oxygenation is the immediate priority. The dose may be repeated in 2 to 3 minutes if there is no response. The 0.4 mg figure is a traditional IV/IM dose, not the intranasal device dose.
- You are dispatched to a school for a 9-year-old with hives, lip swelling, and wheezing after a bee sting. She is anxious and her breathing is labored. Her caregiver hands you her prescribed epinephrine auto-injector. The child weighs about 45 pounds (20 kg). Which dose device should you use?
- The 0.5 mg auto-injector
- No epinephrine until ALS arrives
- The 0.15 mg (junior) auto-injector
- The 0.3 mg (adult) auto-injector
Correct answer: The 0.15 mg (junior) auto-injector
The 0.15 mg junior auto-injector is appropriate for a child of this size. The pediatric (junior) device delivers 0.15 mg and is used for children roughly 15 to 30 kg (about 33 to 66 pounds); the switch to the adult 0.3 mg device generally occurs around 25 kg (about 55 pounds) or more. Epinephrine is the first-line treatment for anaphylaxis and should not be delayed waiting for ALS when the patient has airway and breathing involvement. A 0.5 mg auto-injector is not the standard pediatric option.
- You are dispatched to a 40-year-old woman with sudden facial swelling, difficulty swallowing, and audible wheezing after eating shellfish. She has a prescribed epinephrine auto-injector. What is the correct injection site and technique for administering it?
- Into the abdomen at the umbilicus, holding for 10 seconds
- Into the upper outer arm, holding for 1 second
- Into a vein at the antecubital fossa
- Into the mid-outer thigh, holding firmly for several seconds
Correct answer: Into the mid-outer thigh, holding firmly for several seconds
The mid-outer thigh, held firmly in place for several seconds, is the correct site and technique for an epinephrine auto-injector. The anterolateral (outer) thigh delivers reliable intramuscular absorption and can be given through clothing if needed. The arm, abdomen, and intravenous routes are incorrect; epinephrine auto-injectors are designed exclusively for IM thigh injection.
- You are treating a 25-year-old in anaphylaxis with stridor and hypotension after a wasp sting. After administering the epinephrine auto-injector, which combination best describes the EMT's ongoing priorities during transport?
- Withholding further care until the rash resolves
- Oral antihistamine tablets and reassessment in 30 minutes
- Nasal cannula at 2 L/min and delayed transport
- High-flow oxygen, supine positioning with legs elevated, and rapid transport with ALS rendezvous
Correct answer: High-flow oxygen, supine positioning with legs elevated, and rapid transport with ALS rendezvous
High-flow oxygen, supine positioning with legs elevated, and rapid transport with ALS rendezvous is correct for severe anaphylaxis. Epinephrine is the priority drug, but the EMT must also support breathing and circulation and move quickly because a second epinephrine dose, advanced airway, or other ALS interventions may be needed. Oral antihistamines and delayed transport are inadequate for a life-threatening reaction.
- You are dispatched to a 72-year-old man with sudden right-sided weakness. To screen for a possible stroke using the Cincinnati Prehospital Stroke Scale, which three findings do you assess?
- Facial droop, arm drift, and speech abnormality
- Level of consciousness, capillary refill, and breath sounds
- Pupil size, grip strength, and gag reflex
- Blood pressure, blood glucose, and pulse oximetry
Correct answer: Facial droop, arm drift, and speech abnormality
Facial droop, arm drift, and speech abnormality are the three components of the Cincinnati Prehospital Stroke Scale. The patient is asked to smile (checking for an uneven face), hold both arms out with eyes closed (checking whether one drifts down), and repeat a simple phrase (checking for slurred or wrong words). Any single abnormal finding raises the probability of stroke. Vital signs and reflexes are part of assessment but are not the three scale elements.
- You are dispatched to a 68-year-old woman with slurred speech and left arm weakness that began suddenly. After confirming her airway and breathing are intact, which action is most important for guiding her treatment and destination?
- Asking about her family history of cancer
- Establishing the exact time the patient was last known well
- Obtaining a complete list of childhood illnesses
- Measuring her core body temperature
Correct answer: Establishing the exact time the patient was last known well
Establishing the exact time the patient was last known well is the most important step in suspected stroke. This time determines eligibility for time-sensitive therapies such as clot-dissolving medication or thrombectomy and helps EMS choose the appropriate stroke-capable hospital. Checking blood glucose to rule out hypoglycemia is also valuable, but the last-known-well time directly drives treatment decisions. Childhood illnesses and cancer family history are not relevant to acute stroke triage.
- You are caring for an unresponsive 55-year-old man who is breathing adequately on his own with no suspected trauma. He has vomited once. To protect his airway during transport, what is the most appropriate positioning?
- Prone with the face down
- Supine with the head flat
- The recovery position on his side
- Sitting fully upright in a chair
Correct answer: The recovery position on his side
The recovery position, lying on the side, is most appropriate for an unresponsive patient who is breathing adequately and has no suspected spinal injury. This lateral position allows secretions and vomit to drain from the mouth and helps keep the tongue from blocking the airway. Lying supine increases aspiration and obstruction risk, and prone positioning impairs breathing and monitoring. If trauma is suspected, the patient would instead be kept in spinal alignment with airway maintained.
- You are managing an unconscious 60-year-old man with no gag reflex and snoring respirations. You decide to insert an oropharyngeal airway. How should you size the device before insertion?
- Measure from the corner of the mouth to the angle of the jaw
- Measure from the tip of the nose to the earlobe
- Use the largest airway in the kit regardless of size
- Measure from the chin to the suprasternal notch
Correct answer: Measure from the corner of the mouth to the angle of the jaw
Measuring from the corner of the mouth to the angle of the jaw (or earlobe) gives the correct oropharyngeal airway size. An airway that is too long can push the epiglottis against the glottis and obstruct the airway, while one that is too short fails to hold the tongue forward. Measuring from the nose to the earlobe is the method for a nasopharyngeal airway, not an oral airway.
- You are inserting an oropharyngeal airway in an unresponsive adult. What is the correct insertion technique for this patient?
- Insert it with the tip pointing toward the cheek and rotate it 90 degrees
- Lubricate it and pass it through the nostril
- Insert it upside down toward the roof of the mouth, then rotate it 180 degrees as it advances
- Insert it straight in following the natural curve with no rotation
Correct answer: Insert it upside down toward the roof of the mouth, then rotate it 180 degrees as it advances
Inserting the oropharyngeal airway upside down (tip toward the roof of the mouth) and rotating it 180 degrees as it advances is the standard adult technique. This rotation helps depress the tongue rather than push it back into the throat. A tongue blade with straight insertion is the alternative method, especially in children, where the rotation technique can injure the palate. The nostril route describes a nasopharyngeal airway.
- You are treating a 35-year-old with a head injury who is semiconscious with a clenched jaw and snoring respirations but still has an intact gag reflex. Which airway adjunct is most appropriate?
- A nasopharyngeal airway
- A bite block taped in place
- An oropharyngeal airway
- No adjunct, only manual positioning
Correct answer: A nasopharyngeal airway
A nasopharyngeal airway is most appropriate for a semiconscious patient who has an intact gag reflex. It is generally tolerated without stimulating the gag reflex, unlike an oral airway, and it bypasses a clenched jaw. The nasopharyngeal airway is sized from the nostril to the earlobe and lubricated before insertion. It is avoided when there are signs of a serious head or facial fracture with possible skull-base injury.
- You are dispatched to a 70-year-old woman with severe shortness of breath, cyanosis around the lips, and a pulse oximetry reading of 84 percent. Which oxygen delivery device and flow rate is most appropriate for her?
- Bag-valve mask only if she stops breathing
- Nasal cannula at 6 L/min
- Nasal cannula at 2 L/min
- Non-rebreather mask at 15 L/min
Correct answer: Non-rebreather mask at 15 L/min
A non-rebreather mask at 15 L/min is most appropriate for a patient with severe hypoxia and adequate spontaneous breathing. The non-rebreather can deliver roughly 80 to 95 percent oxygen, which is what this critically hypoxic patient needs. A nasal cannula delivers far lower oxygen concentrations and is reserved for mild needs or patient comfort. A bag-valve mask is for inadequate or absent breathing, not for a patient who is breathing adequately on her own.
- You are setting up a non-rebreather mask for a hypoxic patient. To deliver the highest possible oxygen concentration, the reservoir bag must be functioning correctly. What is the minimum flow rate required to keep the reservoir bag inflated?
- At least 10 to 15 L/min
- Exactly 4 L/min
- No specific minimum is needed
- At least 6 L/min
Correct answer: At least 10 to 15 L/min
A non-rebreather mask requires at least 10 to 15 L/min, generally run at 15 L/min, to keep the reservoir bag from collapsing during inhalation. If the bag deflates on inspiration the patient is not receiving the intended high oxygen concentration. Before placing the mask, the EMT fills the reservoir bag by occluding the valve. Flows of 4 to 6 L/min are too low to support the reservoir and are used with a nasal cannula instead.
- You are giving low-flow oxygen by nasal cannula to a stable patient with mild shortness of breath. What is the appropriate flow-rate range for a nasal cannula?
- 12 to 15 L/min
- 8 to 10 L/min
- 15 to 25 L/min
- 1 to 6 L/min
Correct answer: 1 to 6 L/min
A nasal cannula is run at 1 to 6 L/min, delivering roughly 24 to 44 percent oxygen. Flow rates above 6 L/min do not meaningfully increase the delivered concentration and dry out and irritate the nasal passages. Higher flows of 10 to 15 L/min belong to masks such as the non-rebreather. The nasal cannula is best for patients who need only modest supplemental oxygen or who cannot tolerate a mask.
- You are deciding between a nasal cannula and a non-rebreather mask for two different patients. Which statement correctly contrasts these two oxygen delivery devices?
- Both devices deliver the same oxygen concentration at any flow rate
- A nasal cannula should always be used for unresponsive, apneic patients
- A non-rebreather mask delivers a higher oxygen concentration and is used for severely hypoxic patients
- A nasal cannula delivers a higher oxygen concentration than a non-rebreather mask
Correct answer: A non-rebreather mask delivers a higher oxygen concentration and is used for severely hypoxic patients
A non-rebreather mask delivers a higher oxygen concentration (about 80 to 95 percent) and is used for severely hypoxic patients with adequate breathing, while a nasal cannula delivers only about 24 to 44 percent and suits mild needs or patient comfort. The two devices are not interchangeable. Neither is used for an apneic patient, who instead requires positive-pressure ventilation with a bag-valve mask.
- You arrive to find a 50-year-old man in cardiac arrest. Bystanders are doing chest compressions. You attach the automated external defibrillator. In which situation will the AED deliver a shock?
- Whenever an unresponsive patient is found, regardless of rhythm
- When the AED detects a shockable rhythm such as ventricular fibrillation
- When the patient has a weak but present pulse
- When the patient is breathing agonally but has organized electrical activity
Correct answer: When the AED detects a shockable rhythm such as ventricular fibrillation
An AED delivers a shock only when it detects a shockable rhythm such as ventricular fibrillation or pulseless ventricular tachycardia. The device analyzes the heart's electrical activity and advises a shock for these disorganized, fatal rhythms. It will not shock organized rhythms with a pulse or asystole. The AED is applied to pulseless, unresponsive patients who are not breathing normally, and compressions resume immediately after any shock.
- You and your partner are performing CPR on an adult in cardiac arrest with a bag-valve mask available. What is the correct compression-to-ventilation ratio and compression rate?
- Continuous compressions with no ventilations
- 15 compressions to 2 breaths at 80 per minute
- 30 compressions to 2 breaths at 100 to 120 per minute
- 5 compressions to 1 breath at 60 per minute
Correct answer: 30 compressions to 2 breaths at 100 to 120 per minute
For an adult, the correct ratio is 30 compressions to 2 breaths with a compression rate of 100 to 120 per minute, whether one or two rescuers are present. Compressions should be at least 2 inches deep with full chest recoil and minimal interruptions. The 15-to-2 ratio applies to two-rescuer child and infant CPR, not adults.
- You are dispatched to a 27-year-old having a generalized seizure on the floor of a restaurant. The patient is shaking and not responsive. What is the most appropriate immediate management by an EMT?
- Forcefully restrain the limbs to stop the movements
- Protect the patient from injury and manage the airway after the seizure stops
- Place a padded object between the teeth to protect the tongue
- Immediately give oral glucose by mouth
Correct answer: Protect the patient from injury and manage the airway after the seizure stops
Protecting the patient from injury and managing the airway after the seizure stops is the correct approach. During the seizure the EMT clears the area of hazards, cushions the head, and avoids restraining the patient; once the seizure ends the patient is placed in the recovery position, the airway is suctioned if needed, and oxygen is given. Forcing anything into the mouth can break teeth or cause aspiration, and nothing should be given by mouth while the patient is actively seizing or unresponsive.
- You are dispatched to a 45-year-old known diabetic who is confused, diaphoretic, and shaky. He is awake and able to follow commands and swallow. His symptoms suggest low blood sugar. Which treatment is within EMT scope?
- Administer oral glucose between the cheek and gum
- Start an IV and push dextrose
- Withhold all treatment until blood glucose is confirmed at the hospital
- Give an intramuscular insulin injection
Correct answer: Administer oral glucose between the cheek and gum
Administering oral glucose between the cheek and gum is the correct EMT treatment for a conscious, alert patient with suspected hypoglycemia who can swallow and protect the airway. Oral glucose is given only when the patient can manage their own airway; it is withheld from anyone who is unconscious or cannot swallow because of aspiration risk. Insulin and IV dextrose are outside EMT scope, and treatment of a symptomatic patient should not be delayed until hospital arrival.
- You are treating a 22-year-old with severe arterial bleeding from a deep laceration to the forearm. Bright red blood is spurting from the wound. What is the correct initial step to control the bleeding?
- Apply ice to the wound and reassess in 10 minutes
- Apply firm direct pressure to the wound with a gloved hand or dressing
- Elevate the arm and wait for clotting
- Apply a tourniquet immediately as the first action
Correct answer: Apply firm direct pressure to the wound with a gloved hand or dressing
Applying firm direct pressure to the wound is the correct first step for controlling external bleeding. Direct pressure stops most hemorrhage, and additional dressings can be added on top without removing the originals. If direct pressure fails to control life-threatening extremity bleeding, the EMT escalates to a tourniquet. Elevation alone and ice are not reliable methods for stopping significant arterial bleeding.
- You are treating a 19-year-old with severe, pulsating bleeding from a partial leg amputation. Direct pressure has not controlled it and he is becoming pale. You decide to apply a tourniquet. Where should you place it?
- On the limb 2 to 3 inches proximal to the wound, not over a joint
- Directly over the wound
- Over a joint such as the knee
- On the limb distal to the wound, toward the foot
Correct answer: On the limb 2 to 3 inches proximal to the wound, not over a joint
A tourniquet is placed on the limb 2 to 3 inches proximal to (above) the wound and not directly over a joint. It is tightened until the bright red bleeding stops and the time of application is noted. Placing it over the wound or over a joint prevents adequate compression of the artery, and placing it distal to the wound would fail to stop the inflow of blood. A tourniquet is indicated when life-threatening extremity bleeding is not controlled by direct pressure.
- You are dispatched to a 30-year-old who fell 15 feet from a ladder. He has neck pain and tingling in both hands. After manually stabilizing the head, you prepare to apply a cervical collar. What is the most important step to ensure the collar is applied correctly?
- Choose any collar size and tighten it firmly
- Properly size the collar to the patient before applying it while maintaining manual in-line stabilization
- Release manual stabilization as soon as the collar touches the neck
- Apply the collar before assessing distal motor and sensory function
Correct answer: Properly size the collar to the patient before applying it while maintaining manual in-line stabilization
Properly sizing the collar to the patient while maintaining manual in-line stabilization is essential. A collar that is too large allows the head to move and one that is too small can hyperextend or compress the neck. Manual stabilization is held continuously until the patient is fully secured to the device, because a collar alone does not immobilize the spine. Distal motor, sensory, and circulatory checks should be done before and after application.
- You are caring for a 40-year-old involved in a high-speed crash who reports midline neck tenderness and is alert. Which approach best reflects current EMT practice for spinal care?
- Apply spinal motion restriction, keeping the spine in neutral alignment and minimizing movement
- Apply long-board immobilization for every trauma patient regardless of findings
- Tightly strap the head before assessing the airway
- Allow the patient to walk to the ambulance to self-limit pain
Correct answer: Apply spinal motion restriction, keeping the spine in neutral alignment and minimizing movement
Applying spinal motion restriction, keeping the spine in neutral alignment and minimizing movement, reflects current practice. Modern protocols favor selective spinal motion restriction for patients with concerning mechanism and findings such as midline tenderness, rather than routinely placing every trauma patient on a long backboard. A cervical collar plus a padded stretcher with careful handling often achieves the goal. The airway always takes priority over securing the head.
- You are immobilizing a patient with a suspected cervical spine injury. After applying a properly sized cervical collar, what additional step is required to achieve adequate c-spine immobilization?
- Have the patient hold their own head still
- The collar alone provides complete immobilization
- Secure the head and torso to a rigid device so the head cannot move independently
- Place the patient in the recovery position
Correct answer: Secure the head and torso to a rigid device so the head cannot move independently
Securing the head and torso to a rigid device so the head cannot move independently is required because a cervical collar by itself does not fully immobilize the spine. The collar limits but does not eliminate motion, so manual stabilization is maintained until the head is secured to the stretcher or board with the body. Asking the patient to hold their own head or relying on the collar alone leaves the spine unprotected.
- You are treating a 50-year-old who fell and has an obviously deformed, swollen, painful forearm with intact distal pulses. There is no open wound. What is the correct way to splint this closed fracture?
- Realign the bone to its normal position before splinting
- Immobilize the joint above and the joint below the injury site
- Splint only the area directly over the deformity
- Apply the splint as tightly as possible to prevent any movement
Correct answer: Immobilize the joint above and the joint below the injury site
Immobilizing the joint above and the joint below the injury site is the correct splinting principle for a long-bone fracture. This prevents movement of the broken bone ends, which reduces pain, bleeding, and further soft-tissue damage. EMTs generally splint a deformed extremity in the position found unless the limb is severely angulated with compromised circulation. Distal pulse, motor, and sensory function must be checked before and after splinting, and the splint should be snug but not so tight that it cuts off circulation.
- You are dispatched to a kitchen fire where a 35-year-old has burns to the entire surface of one arm and the entire front of the torso. Using the rule of nines for an adult, approximately what percentage of total body surface area is burned?
- About 36 percent
- About 18 percent
- About 27 percent
- About 9 percent
Correct answer: About 27 percent
About 27 percent is correct. In the adult rule of nines, the entire surface of one arm (front and back) is 9 percent and the entire front of the torso (anterior trunk: chest and abdomen) is 18 percent. Adding these gives 9 plus 18, which equals about 27 percent. The rule of nines lets EMTs rapidly estimate burn extent to guide fluid needs and transport decisions.
- You are treating a 28-year-old with partial-thickness (second-degree) burns to the forearm from hot grease. The skin is red, blistered, and very painful. What is the most appropriate EMT care for this burn?
- Break the blisters to relieve pressure
- Apply butter or ointment to soothe the skin
- Stop the burning process, cool the area briefly, then cover with a dry sterile dressing
- Pack the burn in ice for the duration of transport
Correct answer: Stop the burning process, cool the area briefly, then cover with a dry sterile dressing
Stopping the burning process, cooling the area briefly, and covering with a dry sterile dressing is the correct approach. Cooling limits ongoing tissue damage, and a dry sterile dressing protects the wound and reduces infection risk and pain from air exposure. Butter and ointments trap heat and contaminate the wound, blisters should not be broken, and prolonged ice can worsen tissue injury and cause hypothermia.
- You are managing a critically injured trauma patient with internal bleeding, hypotension, and a deteriorating mental status. The receiving trauma center is 12 minutes away. Which transport philosophy best applies to this patient?
- Stay and play, performing every possible intervention on scene
- Load and go, limiting on-scene time and performing interventions en route
- Cancel transport and wait for ALS to arrive on scene
- Delay transport until vital signs normalize
Correct answer: Load and go, limiting on-scene time and performing interventions en route
Load and go, limiting on-scene time and performing interventions during transport, applies to this unstable trauma patient. Patients with conditions an EMT cannot fix in the field, such as internal hemorrhage, need rapid surgical care, so minimizing scene time and moving toward the trauma center is the priority. Stay and play is reserved for stable patients who benefit from on-scene treatment, and delaying transport to normalize vitals would waste the limited time this patient has.
- You are an EMT treating a patient with a suspected stroke who has a depressed level of consciousness and cannot protect their own airway. You are 25 minutes from the hospital. Which situation most clearly warrants requesting ALS intercept?
- A patient who simply prefers a faster ride
- A patient whose family requests a specific hospital
- A patient who needs advanced airway management or interventions beyond EMT scope
- A stable patient with a minor, isolated wrist injury
Correct answer: A patient who needs advanced airway management or interventions beyond EMT scope
A patient who needs advanced airway management or interventions beyond EMT scope is the situation that warrants calling for ALS. ALS providers can perform procedures such as advanced airways, IV medications, and cardiac monitoring that an EMT cannot. Requesting ALS for a stable minor injury, a preference for speed, or a hospital choice is not appropriate and can divert limited resources. The EMT should continue care and rendezvous with ALS as soon as possible.
- You are preparing to assist a patient with their prescribed nitroglycerin for chest pain. Before giving any medication, which set of checks best represents the rights of medication administration an EMT should confirm?
- Right patient, right medication, right dose, right route, and right time
- Right blood type, right allergy band, and right room number
- Right hospital, right insurance, right family, and right paperwork
- Right partner, right vehicle, and right radio channel
Correct answer: Right patient, right medication, right dose, right route, and right time
Right patient, right medication, right dose, right route, and right time are the core rights of medication administration for an EMT. Confirming these (often expanded to include right documentation) prevents medication errors before any drug is given. The EMT also verifies the medication is not expired, the patient has no contraindication, and obtains consent. The other choices describe administrative or unrelated checks, not medication safety rights.
- You are treating a 60-year-old man with chest pain who has a valid nitroglycerin prescription and a systolic blood pressure of 140 mmHg. After confirming there are no contraindications, how is nitroglycerin administered by an EMT?
- Inhaled through a nebulizer
- Swallowed as a whole tablet with water
- Placed under the tongue (sublingually) and allowed to dissolve
- Injected into the thigh muscle
Correct answer: Placed under the tongue (sublingually) and allowed to dissolve
Nitroglycerin is administered sublingually, placed under the tongue and allowed to dissolve, as a tablet or spray. The sublingual route allows rapid absorption to relieve cardiac chest pain. The EMT reassesses blood pressure before and after each dose and typically may assist with up to three doses about 5 minutes apart as long as the systolic pressure stays above 100 mmHg. Swallowing, injecting, or nebulizing nitroglycerin are not correct routes.
- You are dispatched to a residential overdose. After your patient is treated and stabilized, your partner asks why EMTs cannot administer a medication that requires inserting a needle into a vein. Which statement best describes the EMT scope of practice for medication administration?
- EMTs may give intravenous medications only if a paramedic verbally authorizes it on scene
- EMTs are generally limited to assisting with, administering, or facilitating medications by routes such as oral, sublingual, intramuscular, intranasal, inhaled, and auto-injector, but not by intravenous push
- EMTs have no authority to administer any medication and may only transport
- EMTs may establish peripheral intravenous lines and push any medication carried on the ambulance
Correct answer: EMTs are generally limited to assisting with, administering, or facilitating medications by routes such as oral, sublingual, intramuscular, intranasal, inhaled, and auto-injector, but not by intravenous push
The EMT scope of practice generally limits medication delivery to non-IV routes such as oral, sublingual, intramuscular, intranasal, inhaled, and auto-injector, and does not include starting IV lines or giving IV-push medications. Scope of practice is defined by the National EMS Scope of Practice Model and then set by each state and medical director, so EMTs perform basic-level skills until an advanced provider is available. Starting an IV and pushing medications is an Advanced EMT or paramedic skill, which is why a paramedic's verbal okay does not expand an EMT's legal scope.
- You arrive to find an unconscious adult who is not breathing adequately. No family members are present to authorize treatment. Under which legal principle are you permitted to begin emergency care?
- Implied consent
- Involuntary consent
- Informed consent
- Expressed consent
Correct answer: Implied consent
Implied consent allows you to treat an unconscious or otherwise incapacitated patient who cannot give permission, based on the assumption that a reasonable person would consent to lifesaving care if able. Expressed consent must be actively given by an alert, competent adult, so it does not apply here because the patient cannot communicate. Implied consent only applies until the patient regains capacity and can accept or refuse care themselves.
- You respond to a minor car crash. A 40-year-old alert, oriented driver with no injuries states he does not want to be evaluated or transported. What is required for this refusal of care to be valid?
- A family member must sign the refusal form on the patient's behalf
- Refusal is automatically valid for any patient who can speak
- The patient must be transported anyway because all crash patients require evaluation
- The patient must have decision-making capacity, be informed of the risks of refusing, and demonstrate understanding of those risks
Correct answer: The patient must have decision-making capacity, be informed of the risks of refusing, and demonstrate understanding of those risks
A valid refusal of care requires that the patient have decision-making capacity, be fully informed of the risks of refusing, and demonstrate understanding of those risks, ideally restating them in his own words. A competent adult has the right to refuse treatment and transport even when that refusal could lead to harm. You cannot force transport on a patient with capacity, and a third party cannot refuse on behalf of a competent adult, so the key is confirming and documenting the patient's capacity and informed decision.
- You are using START triage at a bus collision. A patient is breathing at 36 breaths per minute. Before assessing anything else, which triage category does this finding alone direct you to assign?
- Delayed (yellow)
- Immediate (red)
- Minor (green)
- Expectant (black)
Correct answer: Immediate (red)
A respiratory rate over 30 breaths per minute in START triage immediately assigns the patient to the Immediate (red) category, so a rate of 36 means you tag the patient red and move on. START evaluates Respirations, Perfusion, and Mental status (RPM 30-2-Can Do), and failing any single threshold makes the patient Immediate. You do not continue to assess perfusion or mental status once the respiratory criterion already places the patient in the red category.
- While performing START triage, your first action upon arriving at the group of patients is to direct everyone who is able to walk to move to a designated area. What is the purpose of this step?
- To begin treating the most critically injured patients first
- To quickly identify and categorize the walking wounded as Minor (green) so resources can focus on those who cannot walk
- To determine which patients are deceased
- To clear the scene of bystanders who are not patients
Correct answer: To quickly identify and categorize the walking wounded as Minor (green) so resources can focus on those who cannot walk
Directing everyone who can walk to a designated area rapidly sorts out the walking wounded, who are categorized as Minor (green) because their ability to follow the command and ambulate indicates they are not in immediate danger. This frees responders to concentrate on patients who cannot walk and are more likely to be critically injured. START is designed for speed, so this single command efficiently removes the lowest-priority group from the assessment line in seconds.
- You are assigning MCI triage tags. A patient has severe injuries that are likely survivable only with immediate intervention, a second patient has serious injuries but can wait, and a third has no spontaneous breathing even after a single airway repositioning attempt. Which describes the correct categories for these three patients in order?
- Delayed, Immediate, Minor
- Minor, Immediate, Delayed
- Immediate, Delayed, Expectant
- Expectant, Minor, Immediate
Correct answer: Immediate, Delayed, Expectant
The patient needing immediate lifesaving intervention is Immediate (red), the patient with serious but non-life-threatening injuries who can wait is Delayed (yellow), and the patient who has no spontaneous respirations after a single airway repositioning attempt is Expectant or deceased (black). The four standard MCI triage categories are Immediate, Delayed, Minor, and Expectant/deceased. The black category is reserved for those without spontaneous breathing after one airway attempt or with injuries incompatible with life, which is why the apneic patient is not tagged red.
- You are dispatched to a reported chemical leak at a warehouse. As you approach, you notice a placard and a vapor cloud. What is your most appropriate immediate action regarding scene safety?
- Stop uphill and upwind at a safe distance, stage, and use binoculars and a reference guide to identify the hazard before approaching
- Drive directly to the patients to begin care as quickly as possible
- Enter the building wearing only standard gloves and eye protection
- Park downwind so the vapor blows away from the patients
Correct answer: Stop uphill and upwind at a safe distance, stage, and use binoculars and a reference guide to identify the hazard before approaching
At a possible hazmat scene you should stop uphill and upwind at a safe distance, stage there, and use binoculars and a reference guide such as the Emergency Response Guidebook to identify the material before approaching. Rushing in can make you a casualty and remove you as a resource. EMTs typically operate in the cold zone and do not enter contaminated areas without proper specialized training and protective equipment, so standard gloves and eye protection are not adequate hazmat PPE.
- At a hazardous materials incident, your ambulance and treatment area should be positioned in which control zone?
- The hot zone, where the contamination is located
- The cold zone, where command, staging, and treatment are located
- The warm zone, where decontamination occurs
- Directly downwind of the spill for fastest patient access
Correct answer: The cold zone, where command, staging, and treatment are located
The cold zone is the safe, uncontaminated area where command, staging, and patient treatment are located, so your ambulance and treatment area belong there. The hot zone is the contaminated area where only specially trained and protected personnel operate, and the warm zone is the controlled corridor where decontamination takes place. EMTs without hazmat-entry training and PPE remain in the cold zone and receive patients after they have been decontaminated.
- A patient exposed to a liquid chemical is brought toward your treatment area at a hazmat incident. What must occur before this patient enters the cold zone for your care?
- The patient must be decontaminated, typically in the warm zone, to remove the contaminant
- The patient must be transported immediately without any further steps
- The patient must sign a refusal form
- The patient must be intubated by an EMT
Correct answer: The patient must be decontaminated, typically in the warm zone, to remove the contaminant
The patient must be decontaminated, typically in the warm zone, to remove the contaminant before entering the cold zone where EMTs provide care. Decontamination protects responders, equipment, and the ambulance from secondary contamination. Treating or transporting a still-contaminated patient can expose providers and spread the hazard, which is why decon is completed first and EMTs receive the patient afterward.
- You are the first EMS unit to arrive at a multiple-vehicle crash with several patients. Under the Incident Command System, what is your most appropriate initial action?
- Wait inside the ambulance until a supervisor arrives to take command
- Transport the first patient you reach and leave the scene
- Begin treating the most seriously injured patient and ignore overall coordination
- Establish command, perform a scene size-up, and communicate a situation report requesting appropriate resources
Correct answer: Establish command, perform a scene size-up, and communicate a situation report requesting appropriate resources
As the first arriving unit you should establish command, complete a scene size-up, and radio a situation report requesting the resources the incident requires. The Incident Command System provides a standardized structure so that responders coordinate under a single command rather than acting independently. Beginning patient care without organizing the response, or waiting passively, delays the coordinated resource request that an evolving multiple-patient scene needs.
- You are transporting a patient and an emergency response with lights and siren is justified. Approaching a red light at a busy intersection, what does the principle of due regard require?
- Turn off all warning devices and treat the intersection like a normal vehicle
- Come to a complete or near stop, ensure other drivers have yielded, and proceed only when it is safe
- Proceed through the intersection at full speed because emergency vehicles always have the right of way
- Use the siren but maintain speed without slowing
Correct answer: Come to a complete or near stop, ensure other drivers have yielded, and proceed only when it is safe
Due regard requires that, even during a justified emergency response, the operator slow to a complete or near stop at a controlled intersection, confirm that other drivers have actually yielded, and proceed only when it is safe. Intersections are the highest-risk location for ambulance collisions. The right of way is something other drivers must yield, not something an operator can assume, so proceeding at full speed against a red light violates due regard and endangers everyone.
- Your service is creating guidelines for safe ambulance operation. Which practice best reflects safe ambulance operations and reduces collision risk?
- Reserving lights-and-siren response for time-critical situations and driving at a safe, controlled speed
- Allowing unrestrained providers to ride in the patient compartment for faster access
- Following other vehicles closely to maintain momentum through traffic
- Using lights and siren for every call regardless of the patient's condition
Correct answer: Reserving lights-and-siren response for time-critical situations and driving at a safe, controlled speed
Reserving emergency lights-and-siren response for time-critical situations and driving at a safe, controlled speed is the practice that most reduces collision risk. Studies show lights and siren often save little time while sharply increasing crash danger, so they should be used selectively. Providers should remain restrained whenever possible and maintain a safe following distance, making the other practices unsafe and inconsistent with sound ambulance operations.
- A conscious, alert 25-year-old who appears intoxicated after a fall insists he is fine and refuses all care. He cannot accurately recall what happened or state the risks of refusing. How should you proceed?
- Force him into the ambulance using restraints without contacting medical control
- Honor the refusal immediately because he is awake and speaking
- Leave the scene and document that the patient was uncooperative
- Recognize that his intoxication may impair his decision-making capacity, attempt to persuade him to accept care, involve medical control and law enforcement as needed, and consider treating under implied consent
Correct answer: Recognize that his intoxication may impair his decision-making capacity, attempt to persuade him to accept care, involve medical control and law enforcement as needed, and consider treating under implied consent
Because intoxication may impair decision-making capacity, this patient may not be able to give a valid refusal, so you should attempt to persuade him to accept care, involve medical control and law enforcement as needed, and consider treating under implied consent. A patient who cannot understand his situation or the risks of refusing lacks capacity, and refusal is only valid when capacity is intact. Simply honoring the refusal or abandoning the patient could constitute negligence, while restraining without medical control or law enforcement involvement is inappropriate.
- During START triage you reach a patient who is breathing only after you reposition the airway, with a respiratory rate of 24. According to START, what is the correct action and category?
- Tag the patient Expectant (black) because the airway needed repositioning
- Tag the patient Immediate (red) because spontaneous breathing returned only after an airway intervention
- Tag the patient Delayed (yellow) because the rate is under 30
- Tag the patient Minor (green) and direct them to walk to the treatment area
Correct answer: Tag the patient Immediate (red) because spontaneous breathing returned only after an airway intervention
A patient who begins breathing only after you reposition the airway is tagged Immediate (red) in START, because needing an airway maneuver to restore breathing signals a critical, time-sensitive condition. START allows a single airway repositioning attempt: if breathing returns, the patient is Immediate; if it does not, the patient is Expectant/deceased (black). The respiratory rate threshold is only assessed for patients already breathing spontaneously without intervention, so the rate of 24 does not downgrade this patient.
- In the Incident Command System, the General Staff is commonly divided into four functional sections. Which set correctly names those sections?
- Command, Control, Communication, and Coordination
- Triage, Treatment, Transport, and Staging
- Operations, Planning, Logistics, and Finance/Administration
- Medical, Fire, Police, and Public Works
Correct answer: Operations, Planning, Logistics, and Finance/Administration
The four General Staff sections in the Incident Command System are Operations, Planning, Logistics, and Finance/Administration. This standardized structure lets agencies of any size scale a response and work under unified command. Triage, Treatment, and Transport are functional roles within the medical branch of an EMS response, not the top-level ICS sections, so that grouping describes a sub-area rather than the General Staff.
- You and your partner must move a heavy, unresponsive patient from the floor to the stretcher. Which body-mechanics practice best protects you from injury during this lift?
- Lift quickly with arms fully extended and the load away from your body
- Bend at the waist and lift with your back to keep the load close
- Twist your torso while lifting to reach across the patient
- Keep your back straight, bend at the knees, hold the weight close to your body, and lift with your legs
Correct answer: Keep your back straight, bend at the knees, hold the weight close to your body, and lift with your legs
Safe lifting means keeping your back straight, bending at the knees, holding the patient's weight close to your body, and lifting with the powerful muscles of your legs. This power-lift technique reduces strain on the spine. Bending at the waist, twisting while lifting, or holding the load away from your body all dramatically increase the risk of back injury, which is a leading cause of EMS provider disability.
- Dispatch sends you to stage for a scene involving an active threat where law enforcement has not yet secured the area. What is the most appropriate operational decision?
- Drive directly to the patient because care must begin immediately
- Enter the scene wearing high-visibility clothing for protection
- Cancel the response since the scene is unsafe
- Stage at a safe distance until law enforcement declares the scene secure, then enter to provide care
Correct answer: Stage at a safe distance until law enforcement declares the scene secure, then enter to provide care
You should stage at a safe distance until law enforcement declares the scene secure, then enter to provide patient care. Provider safety is the priority on a violent or unsecured scene, and entering before it is controlled risks making you a casualty. High-visibility clothing does not protect against an active threat, and canceling outright would abandon patients who still need care once the scene is made safe.
- You arrive at an MCI and the Incident Commander asks you to take the role of Transportation officer. Which responsibility falls under this role?
- Establishing the hot, warm, and cold control zones
- Tracking which patients are sent to which hospitals and coordinating ambulances to avoid overloading any single facility
- Performing decontamination of contaminated patients in the warm zone
- Assigning triage tags to patients as they are found
Correct answer: Tracking which patients are sent to which hospitals and coordinating ambulances to avoid overloading any single facility
The Transportation officer tracks which patients are transported to which hospitals and coordinates ambulances so that no single facility is overwhelmed. This role manages destination distribution and vehicle movement at an MCI. Assigning triage tags is the triage officer's job, decontamination is handled by hazmat-trained personnel in the warm zone, and establishing control zones is part of incident command and hazmat operations, so those duties belong to other positions.
- When positioning the ambulance at a highway crash scene, why is the technique commonly called the "fend-off" or "block" position used?
- It allows the driver to leave the scene fastest in an emergency
- It places the ambulance directly behind the wreckage to hide it from view
- It angles the ambulance to create a protected work area and deflect oncoming traffic away from responders
- It keeps the patient compartment doors facing the flow of traffic for quick loading
Correct answer: It angles the ambulance to create a protected work area and deflect oncoming traffic away from responders
Correct answer: angling the ambulance to create a protected work area and deflect oncoming traffic. The fend-off (block) position parks the apparatus at an angle upstream of the crash so the vehicle body shields the responders and pushes traffic away from the work zone. Hiding the wreckage, fast egress, or facing doors toward traffic are not the purpose; protecting the work area is the goal of this scene-safety technique.
- During scene size-up of a trauma patient, what is the FIRST priority an EMT must establish before patient contact?
- The exact mechanism of injury
- Whether the scene is safe to enter
- The patient's chief complaint
- The patient's baseline vital signs
Correct answer: Whether the scene is safe to enter
Correct answer: whether the scene is safe to enter. Scene safety always comes first in the size-up; an injured rescuer cannot help the patient. Mechanism of injury, chief complaint, and vital signs are assessed only after the EMT confirms the scene is safe to approach.
- An EMT will be in contact with a patient who is bleeding and also vomiting. Which combination of standard precautions is MOST appropriate?
- Gloves only
- Gloves, eye protection, and a mask or face shield
- A gown only
- No precautions are needed if the patient appears healthy
Correct answer: Gloves, eye protection, and a mask or face shield
Correct answer: gloves, eye protection, and a mask or face shield. When splashing or splattering of blood or body fluids is likely, standard precautions call for protecting the hands, eyes, and face. Gloves alone do not protect the mucous membranes of the eyes, nose, and mouth, and precautions are based on anticipated exposure, not on how healthy the patient appears.
- On a hazardous materials placard, what does the NFPA 704 "fire diamond" communicate to responders during scene size-up?
- The phone number to call for a tow truck
- Only the name of the manufacturer of the substance
- The number of patients expected at the scene
- The health, flammability, and instability hazards of the material plus any special hazards
Correct answer: The health, flammability, and instability hazards of the material plus any special hazards
Correct answer: the health, flammability, and instability hazards plus special hazards. The NFPA 704 diamond uses blue (health), red (flammability), yellow (instability), and a white quadrant for special hazards, each rated 0-4. It does not list the manufacturer, the number of patients, or towing information; it rapidly conveys the danger level of the material.
- When sizing up a possible hazardous materials release, why is the Emergency Response Guidebook (ERG) used to establish an initial isolation distance?
- It tells the EMT which medications to administer for any exposure
- It lists the names of patients exposed to the substance
- It provides recommended setback distances to keep responders and the public out of the danger zone
- It guarantees the chemical is non-toxic if the distance is observed
Correct answer: It provides recommended setback distances to keep responders and the public out of the danger zone
Correct answer: it provides recommended setback (isolation) distances. The ERG, indexed by placard number or material name, gives initial isolation and protective-action distances so responders stage at a safe distance. It does not list patient names, prescribe treatments, or guarantee a substance is harmless.
- An EMT arrives at a hazardous materials incident and observes the contaminated patients. From which zone should EMS provide patient care?
- The cold zone, after patients have been decontaminated
- The hot zone, immediately upon arrival
- The warm zone, before any decontamination
- Any zone, because gloves provide complete protection
Correct answer: The cold zone, after patients have been decontaminated
Correct answer: the cold zone, after decontamination. EMS without specialized PPE and training operates in the cold zone and treats patients only after they have been decontaminated. The hot zone is the area of contamination and the warm zone is where decon occurs; entering them or relying on gloves alone exposes the EMT to the hazard.
- During scene size-up, which finding should most strongly raise an EMT's suspicion of a potentially violent scene?
- Loud arguing and the sound of breaking objects coming from inside the residence
- A wheelchair ramp at the front entrance
- An open medication bottle on the kitchen table
- A pet dog barking behind a closed door
Correct answer: Loud arguing and the sound of breaking objects coming from inside the residence
Correct answer: loud arguing and breaking objects. These are direct cues of ongoing conflict and potential violence, signaling the EMT to stage and request law enforcement. A wheelchair ramp, a medication bottle, and a barking dog behind a closed door are routine findings that do not by themselves indicate violence.
- While approaching a residence on foot during scene size-up, what is the safest practice when standing at the door?
- Stand squarely centered in front of the door for the best view
- Stand to the side of the doorway rather than directly in front of it
- Immediately force the door open without knocking
- Place all equipment in the doorway to block it open
Correct answer: Stand to the side of the doorway rather than directly in front of it
Correct answer: stand to the side of the doorway. Positioning to the side reduces exposure if someone inside is hostile or fires through the door. Standing centered in front, forcing the door, or blocking the doorway with gear all increase risk rather than protecting the responder.
- At a multiple-casualty incident, what does "staging" accomplish during the early scene size-up?
- It requires all crews to enter the hazard zone at the same time
- It holds incoming units at a safe location until they are assigned, preventing scene congestion and exposure
- It cancels the response of additional resources
- It assigns triage tags directly to the responders
Correct answer: It holds incoming units at a safe location until they are assigned, preventing scene congestion and exposure
Correct answer: it holds incoming units at a safe location until assigned. Staging keeps additional resources out of harm's way and prevents an unsafe, congested scene until command directs them in. It does not send everyone into the hazard, cancel resources, or tag responders.
- When an EMT removes contaminated gloves after patient care, what is the correct technique to minimize self-contamination?
- Leave the gloves on until the end of the entire shift
- Pull both gloves off by the fingertips and reuse them on the next patient
- Peel each glove off inside-out, touching only the inner surfaces, then wash hands
- Wipe the outside of the gloves and place them in a pocket
Correct answer: Peel each glove off inside-out, touching only the inner surfaces, then wash hands
Correct answer: peel each glove off inside-out and wash hands. Turning the gloves inside-out traps the contaminated outer surface inside, and hand hygiene afterward removes residual pathogens. Reusing gloves, wearing them all shift, or pocketing them spreads contamination and defeats the purpose of the precaution.
- During scene size-up at a nighttime roadway incident, what clothing measure best improves an EMT's visibility to passing motorists?
- Wearing a dark navy uniform to look professional
- Wearing a high-visibility reflective safety vest that meets traffic-incident standards
- Carrying a small penlight in a shirt pocket
- Removing the vest so it does not snag on equipment
Correct answer: Wearing a high-visibility reflective safety vest that meets traffic-incident standards
Correct answer: wearing a high-visibility reflective safety vest. Reflective, ANSI-compliant garments make responders visible to drivers and are required when working in or near traffic. A dark uniform reduces visibility, a pocket penlight is inadequate, and removing the vest directly increases the risk of being struck.
- You are dispatched for an unconscious worker inside a partially buried storage tank. Why is this scene treated as a confined space during size-up?
- The only hazard is the difficulty of carrying equipment inside
- It is simply a small room that any EMT can safely enter
- Confined spaces are always safe once a patient is visible
- It has limited entry and exit and may contain an oxygen-deficient or toxic atmosphere, requiring specially trained rescuers
Correct answer: It has limited entry and exit and may contain an oxygen-deficient or toxic atmosphere, requiring specially trained rescuers
Correct answer: limited entry/exit with a possible oxygen-deficient or toxic atmosphere requiring trained rescuers. Confined spaces can harbor invisible hazardous atmospheres that have killed would-be rescuers. Treating it as an ordinary small room, assuming visibility means safety, or viewing equipment access as the only issue all underestimate the lethal atmospheric danger.
- During scene size-up, an EMT notices the patient is in a vehicle that is unstable and rocking on its side. What is the appropriate action?
- Have the patient self-extricate by rocking the vehicle upright
- Climb onto the vehicle immediately to reach the patient
- Ensure the vehicle is stabilized before crew members attempt to access the patient
- Ignore the instability since the patient must be reached quickly
Correct answer: Ensure the vehicle is stabilized before crew members attempt to access the patient
Correct answer: ensure the vehicle is stabilized first. An unstable vehicle can shift and injure both crew and patient, so stabilization (cribbing, struts, or fire/rescue) precedes access. Climbing on, encouraging movement, or ignoring the hazard endangers everyone and is unsafe.
- What is the primary reason an EMT requests additional resources EARLY during scene size-up rather than later?
- Resources can only be requested before leaving the station
- Early requests reduce the amount of paperwork required
- It guarantees the EMT will not have to treat any patients
- Additional units take time to arrive, so early requests prevent delays in care
Correct answer: Additional units take time to arrive, so early requests prevent delays in care
Correct answer: additional units take time to arrive. Because mutual aid, fire, or law enforcement have a response time, requesting them early in the size-up avoids care delays once the need is identified. The reason is not reduced paperwork, avoiding patient care, or a station-only request window.
- An EMT performing scene size-up at an outdoor incident notes the wind is carrying smoke and fumes from a burning vehicle. Where should the EMT and patient be positioned?
- Directly beside the burning vehicle for a faster assessment
- Downwind so the fumes pass over them quickly
- Uphill and upwind of the smoke and fumes
- Downhill so runoff drains away from the patient
Correct answer: Uphill and upwind of the smoke and fumes
Correct answer: uphill and upwind. Smoke, fumes, and many hazardous vapors travel downwind and settle in low areas, so staying uphill and upwind keeps responders and patients out of the contaminated air. Positioning downwind, beside the fire, or downhill places them in the path of the hazard.
- During scene size-up of a structure fire with a reported victim inside, what is the appropriate role of the EMT who is not a trained firefighter?
- Open all windows of the structure to vent the smoke
- Enter the burning structure immediately to retrieve the victim
- Crawl inside with a wet towel over the face
- Remain outside and allow trained fire personnel with proper PPE to perform the rescue
Correct answer: Remain outside and allow trained fire personnel with proper PPE to perform the rescue
Correct answer: remain outside and let trained fire personnel with proper PPE perform the rescue. EMTs lack the turnout gear, SCBA, and training for interior fire operations, so they prepare to receive and treat patients outside. Entering the structure, improvising face protection, or venting windows are firefighting tasks that would endanger an untrained EMT.
- While sizing up a scene, an EMT observes a syringe with an exposed needle on the floor near the patient. What is the safest action?
- Avoid the sharp, take care during movement, and have it safely managed to prevent a needlestick
- Pick the needle up with bare hands and recap it
- Kick the needle aside so the crew can move freely
- Ignore it entirely since gloves prevent all injury
Correct answer: Avoid the sharp, take care during movement, and have it safely managed to prevent a needlestick
Correct answer: avoid the sharp and have it safely managed to prevent a needlestick. Exposed needles transmit bloodborne pathogens, so the EMT works around the hazard and ensures it is handled safely. Bare-handed recapping, kicking it, or relying on gloves to stop a puncture all risk a contaminated needlestick injury.
- During scene size-up at a collision, why does the EMT count and locate ALL patients before beginning care on the first one found?
- Because the first patient seen is always the least injured
- So that adequate resources can be requested and no patient is overlooked
- Because only one patient may be treated per call
- To decide which bystanders should be billed for the response
Correct answer: So that adequate resources can be requested and no patient is overlooked
Correct answer: so adequate resources can be requested and no patient is overlooked. Determining the total number of patients early lets the EMT call for enough ambulances and avoid missing a critically injured victim. The first patient seen is not necessarily least injured, more than one patient can be treated, and billing bystanders is irrelevant to size-up.
- An EMT is dispatched to a possible suicide attempt. During scene size-up, what safety consideration is MOST important?
- Ensure law enforcement has secured the scene and no weapons or means of harm are accessible
- Approach quickly and alone to build rapport before police arrive
- Assume the patient poses no danger because the attempt was directed at themselves
- Leave all equipment in the ambulance to appear non-threatening
Correct answer: Ensure law enforcement has secured the scene and no weapons or means of harm are accessible
Correct answer: ensure law enforcement has secured the scene and no means of harm are accessible. A behavioral or suicidal patient may have weapons and can pose a risk to self and others, so scene security comes first. Approaching alone, assuming no danger, or arriving without equipment do not address the safety threat the scene may present.
- During scene size-up of a winter call on an icy parking lot, what action best protects the EMS crew from injury?
- Ignore the surface conditions because the patient is the only concern
- Run to the patient as fast as possible across the ice
- Move deliberately and account for the slip-and-fall hazard before and during patient access
- Wait inside the warm ambulance until the ice melts on its own
Correct answer: Move deliberately and account for the slip-and-fall hazard before and during patient access
Correct answer: move deliberately and account for the slip-and-fall hazard. Environmental conditions such as ice are a scene-safety hazard that can injure responders, so the crew adjusts movement and footing. Running across the ice risks falls, ignoring the surface invites injury, and waiting for ice to melt unacceptably delays care.
- At a tanker collision, the placard contains a four-digit UN/NA identification number. How does this number assist scene size-up?
- It indicates how many gallons of fuel the truck holds
- It states the total weight of the cargo only
- It is the driver's commercial license number
- It identifies the specific material so responders can look up its hazards and isolation distances
Correct answer: It identifies the specific material so responders can look up its hazards and isolation distances
Correct answer: it identifies the specific material so responders can look up its hazards and isolation distances. The four-digit UN/NA number cross-references the Emergency Response Guidebook to reveal the substance and its protective-action distances. It is not the cargo weight, the driver's license, or the fuel capacity.
- During scene size-up, an EMT determines that the number of patients exceeds the capabilities of the responding units. What does this scene now require?
- Activation of a multiple-casualty incident response, including triage and additional resources
- Transporting all patients in the single available ambulance at once
- Treating each patient fully before assessing the next one
- Canceling the call until more crews are off duty
Correct answer: Activation of a multiple-casualty incident response, including triage and additional resources
Correct answer: activation of a multiple-casualty incident response with triage and additional resources. When patient needs outstrip available resources, the incident becomes an MCI requiring triage to prioritize care and a request for mutual aid. Overloading one ambulance, fully treating each patient serially, or canceling the call would all fail the patients in an MCI.
- When an EMT arrives at a scene that is not yet safe, what is the correct course of action?
- Direct bystanders to carry the patient out of the danger area
- Enter immediately because the patient needs help now
- Wait at the hospital for the patient to be brought in
- Stage at a safe distance and wait for the appropriate agency to make the scene safe
Correct answer: Stage at a safe distance and wait for the appropriate agency to make the scene safe
Correct answer: stage at a safe distance and wait for the appropriate agency to make the scene safe. Responders who enter an unsafe scene risk becoming additional victims, so they hold at a safe location until fire or law enforcement mitigates the hazard. Entering immediately, leaving for the hospital, or sending bystanders into danger are all inappropriate responses.
- During scene size-up at a residence, an EMT smells a strong, unidentified chemical odor upon opening the door. What is the appropriate action?
- Withdraw, keep others out, and request the appropriate specialized resources
- Continue inside while breathing through a cloth
- Open more doors and continue the assessment
- Light a flashlight to see the source of the odor more clearly
Correct answer: Withdraw, keep others out, and request the appropriate specialized resources
Correct answer: withdraw, keep others out, and request specialized resources. An unidentified chemical odor signals a possible toxic or explosive atmosphere, so the EMT retreats and summons hazmat or fire. Pressing on with a cloth, opening doors, or introducing an ignition source like a flashlight could result in poisoning or explosion.
- Why does an EMT begin forming a scene size-up impression based on dispatch information BEFORE arriving on scene?
- It eliminates the need to assess the scene once on location
- Early information allows the crew to anticipate hazards, resources, and the type of incident
- It allows the crew to skip patient assessment entirely
- Dispatch information is always exactly accurate, so no confirmation is needed
Correct answer: Early information allows the crew to anticipate hazards, resources, and the type of incident
Correct answer: early information allows the crew to anticipate hazards, resources, and incident type. Using the dispatch details en route lets the crew mentally prepare and pre-stage requests, but they must still confirm conditions on arrival. It does not replace the on-scene size-up, the patient assessment, or the need to verify information that may be incomplete or wrong.
- At a scene involving downed electrical wires, what is the safest assumption an EMT should make during size-up?
- Assume rubber-soled shoes provide complete protection from the current
- Assume the wires are safe if they are not visibly sparking
- Assume the wires can be moved aside with a dry wooden stick
- Assume every downed wire is energized and dangerous until the utility company confirms otherwise
Correct answer: Assume every downed wire is energized and dangerous until the utility company confirms otherwise
Correct answer: assume every downed wire is energized and dangerous until the utility confirms otherwise. Energized lines can be lethal even without visible sparking, so only the power company should declare them safe. Believing non-sparking wires are safe, moving them with a stick, or trusting footwear to insulate against high voltage are dangerous misconceptions.
- During scene size-up, what does identifying the mechanism of injury help the EMT anticipate?
- The likely types and severity of injuries the patient may have sustained
- The patient's complete past medical history
- The exact medications the patient takes at home
- The patient's insurance and billing information
Correct answer: The likely types and severity of injuries the patient may have sustained
Correct answer: the likely types and severity of injuries. The mechanism of injury describes the forces involved, which helps the EMT predict hidden or serious injuries and maintain an appropriate index of suspicion. It does not reveal the patient's medical history, home medications, or insurance details.
- An EMT responds to a report of a person who collapsed in a grain bin. During scene size-up, what hazard is of greatest concern?
- Engulfment and an oxygen-deficient or toxic atmosphere that can quickly incapacitate rescuers
- Only the difficulty of climbing the exterior ladder
- The dustiness making the patient harder to see
- There is no hazard once the EMT can see the patient
Correct answer: Engulfment and an oxygen-deficient or toxic atmosphere that can quickly incapacitate rescuers
Correct answer: engulfment and an oxygen-deficient or toxic atmosphere that can quickly incapacitate rescuers. Grain bins are confined spaces where flowing grain can bury a person and the atmosphere can be deadly, demanding trained technical rescue. The exterior ladder, reduced visibility, or seeing the patient do not address the lethal engulfment and atmospheric dangers.
- During scene size-up at a domestic violence call, police report the scene is secure but the EMT plans patient care. What ongoing safety practice is appropriate?
- Block the only doorway with the stretcher to control access
- Assume the scene will remain safe for the entire call with no reassessment
- Continuously reassess the scene and keep an exit path available in case conditions change
- Ask the suspect to assist with moving the patient
Correct answer: Continuously reassess the scene and keep an exit path available in case conditions change
Correct answer: continuously reassess the scene and keep an exit path available. Scene safety is dynamic, so even a secured scene must be monitored and the EMT should maintain an escape route. Assuming permanent safety, blocking the only exit, or involving the suspect all undermine the responder's ability to stay safe if the situation deteriorates.
- You arrive to find an unresponsive patient with no obvious trauma. Which manual maneuver should you use first to open the airway during the primary assessment?
- Head-tilt, chin-lift maneuver
- Jaw-thrust maneuver
- Modified Trendelenburg position
- Sellick (cricoid pressure) maneuver
Correct answer: Head-tilt, chin-lift maneuver
Correct answer: Head-tilt, chin-lift maneuver. For an unresponsive medical patient with no suspected spinal injury, the head-tilt, chin-lift is the preferred technique to open the airway because it most effectively lifts the tongue off the posterior pharynx. The jaw-thrust is reserved for suspected spinal injury, Trendelenburg is a positioning for shock not airway opening, and cricoid pressure is not an airway-opening maneuver.
- During the airway portion of a primary assessment on a patient with a suspected cervical-spine injury, which technique opens the airway while minimizing movement of the neck?
- Jaw-thrust maneuver without head extension
- Head-tilt, chin-lift maneuver
- Hyperextending the neck and lifting the chin
- Turning the head to the side to allow drainage
Correct answer: Jaw-thrust maneuver without head extension
Correct answer: Jaw-thrust maneuver without head extension. When spinal injury is suspected, the jaw-thrust maneuver is used because it opens the airway by displacing the mandible forward without moving the cervical spine. The head-tilt, chin-lift and hyperextension both move the neck, and turning the head can worsen a spinal injury.
- You insert an oropharyngeal airway in an unresponsive patient during the primary assessment, and the patient gags and tries to push it out. What is the most appropriate action?
- Tape the airway in place to keep it secure
- Remove the oropharyngeal airway immediately
- Push the airway in further to seat it correctly
- Replace it with a larger oropharyngeal airway
Correct answer: Remove the oropharyngeal airway immediately
Correct answer: Remove the oropharyngeal airway immediately. A gag reflex indicates the patient cannot tolerate an OPA and may vomit and aspirate, so the device must be removed at once. Taping it in or advancing it risks aspiration, and a larger OPA would also trigger the gag reflex; a nasopharyngeal airway would be a better choice if an adjunct is still needed.
- While completing the breathing assessment, you observe an apneic patient taking occasional gasping breaths that are slow and irregular. How should you classify and treat this finding?
- Adequate breathing requiring only oxygen by nasal cannula
- Normal compensatory breathing requiring no intervention
- Hyperventilation requiring coaching to slow the rate
- Agonal respirations that should be treated as inadequate breathing
Correct answer: Agonal respirations that should be treated as inadequate breathing
Correct answer: Agonal respirations that should be treated as inadequate breathing. Agonal gasps are sporadic, gasping breaths that do not provide effective ventilation and are a sign of inadequate breathing or impending cardiac arrest; the patient needs positive-pressure ventilation. They are not adequate breathing, not normal compensation, and are the opposite of hyperventilation.
- You are sizing up a chaotic scene before reaching an injured patient. Determining the number of patients during scene size-up most directly affects which decision?
- The Glasgow Coma Scale score you will assign
- The patient's capillary refill time
- Whether additional resources or mutual aid are needed
- The chief complaint documented in the report
Correct answer: Whether additional resources or mutual aid are needed
Correct answer: Whether additional resources or mutual aid are needed. Identifying the number of patients during scene size-up tells you whether your crew can manage the call or whether you must request more ambulances or initiate a mass-casualty response. It does not determine a GCS score, capillary refill, or the chief complaint, which are patient-level findings.
- During scene size-up before patient contact, which two factors guide your suspicion of injuries and your level of clinical concern?
- Blood pressure and pulse rate
- Glasgow Coma Scale and AVPU
- Mechanism of injury and nature of illness
- Capillary refill and skin color
Correct answer: Mechanism of injury and nature of illness
Correct answer: Mechanism of injury and nature of illness. During scene size-up you evaluate the mechanism of injury for trauma patients and the nature of illness for medical patients to anticipate likely problems before hands-on assessment. Blood pressure, pulse, GCS, AVPU, capillary refill, and skin color are findings gathered during the patient assessment, not the scene size-up.
- You complete your primary assessment of a critically injured trauma patient and identify multiple life threats. This finding should drive which transport decision?
- Delay transport until a full secondary assessment is finished on scene
- Cancel additional resources because you have stabilized the patient
- Downgrade the response to non-emergency transport
- Make a rapid transport decision and limit on-scene time
Correct answer: Make a rapid transport decision and limit on-scene time
Correct answer: Make a rapid transport decision and limit on-scene time. When the primary assessment reveals serious life threats, the patient is a high priority for rapid transport, and on-scene time should be minimized so definitive care is not delayed. Completing a full secondary on scene, canceling resources, or downgrading the response would all dangerously delay care for an unstable patient.
- You are forming a general impression of a 2-year-old as you enter the room. Which standardized tool is designed to rapidly assess a pediatric patient from across the room before touching them?
- The Glasgow Coma Scale
- The Pediatric Assessment Triangle
- The Cincinnati Stroke Scale
- The Rule of Nines
Correct answer: The Pediatric Assessment Triangle
Correct answer: The Pediatric Assessment Triangle. The Pediatric Assessment Triangle evaluates appearance, work of breathing, and circulation to the skin, forming a rapid hands-off general impression of a child's status. The Glasgow Coma Scale measures level of consciousness in detail, the Cincinnati Stroke Scale screens for stroke, and the Rule of Nines estimates burn surface area.
- You assess an infant's circulation during the primary assessment and cannot reliably locate a radial pulse. Which pulse site is preferred for checking circulation in an infant?
- The brachial pulse in the upper arm
- The carotid pulse in the neck
- The dorsalis pedis pulse on the foot
- The temporal pulse at the head
Correct answer: The brachial pulse in the upper arm
Correct answer: The brachial pulse in the upper arm. In infants, the brachial pulse on the inner upper arm is the recommended site to assess circulation because the short, chubby neck makes the carotid difficult to palpate. The carotid is preferred in adults and children, while the dorsalis pedis and temporal pulses are not standard primary-assessment circulation checks for infants.
- During the breathing portion of a primary assessment, you attach a pulse oximeter that reads 86 percent on room air in a patient with labored breathing. How should this value be interpreted?
- Normal oxygenation that requires no intervention
- Evidence the airway is fully patent and protected
- A reliable measure of ventilation and carbon dioxide levels
- Hypoxia indicating the patient needs supplemental oxygen
Correct answer: Hypoxia indicating the patient needs supplemental oxygen
Correct answer: Hypoxia indicating the patient needs supplemental oxygen. An SpO2 of 86 percent is well below the normal range of 94 to 99 percent and signals hypoxia, so the patient should receive supplemental oxygen. It is not normal, it does not confirm airway patency, and pulse oximetry measures oxygen saturation rather than ventilation or carbon dioxide.
- You are managing an unresponsive patient during the primary assessment whose airway is filling with vomit. What is the immediate priority before continuing the assessment?
- Apply a non-rebreather mask at 15 liters per minute
- Check the radial pulse and skin temperature
- Suction the airway to clear the secretions
- Obtain a full set of baseline vital signs
Correct answer: Suction the airway to clear the secretions
Correct answer: Suction the airway to clear the secretions. A patent airway is the foundation of the primary assessment, so vomit must be suctioned immediately to prevent aspiration before any other step. Applying oxygen over an obstructed airway, checking circulation, or obtaining vitals would all be premature while the airway is compromised.
- During the primary assessment, an EMT decides to insert a nasopharyngeal airway rather than an oropharyngeal airway in a semiconscious patient with an intact gag reflex. What is the main advantage of this choice?
- It guarantees the airway is protected from aspiration
- It is the preferred adjunct in suspected skull fractures
- It is better tolerated in patients with an intact gag reflex
- It eliminates the need to maintain a manual airway position
Correct answer: It is better tolerated in patients with an intact gag reflex
Correct answer: It is better tolerated in patients with an intact gag reflex. A nasopharyngeal airway can be used in patients who still have a gag reflex because it is less likely to stimulate gagging than an oropharyngeal airway. It does not definitively protect against aspiration, it is contraindicated with suspected skull fractures, and a manual airway position may still be required.
- You are completing the circulation step of the primary assessment on a trauma patient and find a large pool of bright red blood spurting from a thigh wound. What is the correct priority action?
- Continue to the disability assessment and treat bleeding later
- Obtain a blood pressure before intervening
- Control the major external bleeding immediately
- Document the estimated blood loss and reassess in five minutes
Correct answer: Control the major external bleeding immediately
Correct answer: Control the major external bleeding immediately. Life-threatening external hemorrhage found during the circulation step of the primary assessment must be controlled at once with direct pressure or a tourniquet because it can rapidly cause death. Continuing the assessment, taking a blood pressure first, or only documenting the loss would dangerously delay treatment of an immediate life threat.
- While assessing breathing on an adult, you count a respiratory rate of 6 breaths per minute with shallow chest rise. Which intervention does this finding require?
- Oxygen by nasal cannula at 2 liters per minute
- Positive-pressure ventilation with a bag-valve mask
- Coaching the patient to breathe more slowly
- No intervention because the rate is within normal limits
Correct answer: Positive-pressure ventilation with a bag-valve mask
Correct answer: Positive-pressure ventilation with a bag-valve mask. A rate of 6 with shallow chest rise is inadequate breathing because both the rate and tidal volume are too low to maintain ventilation, so the patient needs assisted ventilations with a bag-valve mask. A nasal cannula cannot correct inadequate ventilation, slowing the rate would worsen it, and the finding is clearly abnormal.
- During the primary assessment you are deciding whether a patient is a high priority for immediate transport. Which finding most clearly identifies a high-priority patient?
- A blood pressure of 128 over 78
- An altered level of consciousness with poor perfusion
- A complaint of mild ankle pain after a twist
- A pulse oximetry reading of 98 percent on room air
Correct answer: An altered level of consciousness with poor perfusion
Correct answer: An altered level of consciousness with poor perfusion. Altered mental status combined with signs of poor perfusion indicates a serious threat to life and marks the patient as a high transport priority. A normal blood pressure, an isolated minor injury, and a normal oxygen saturation are not high-priority findings.
- You approach an adult who appears asleep in a chair. To begin the primary assessment, you tap the shoulders and shout. What are you assessing with this action?
- The patient's capillary refill time
- The patient's pupillary response to light
- The patient's blood glucose level
- The patient's responsiveness and level of consciousness
Correct answer: The patient's responsiveness and level of consciousness
Correct answer: The patient's responsiveness and level of consciousness. Tapping and shouting is the first step in determining responsiveness, which establishes the patient's level of consciousness at the start of the primary assessment. It does not measure capillary refill, pupillary response, or blood glucose, which are assessed by other techniques.
- You determine that an unresponsive adult is not breathing normally and has no pulse during the primary assessment. According to current resuscitation priorities for this scenario, what should you do first?
- Give two rescue breaths before anything else
- Insert an advanced airway before any compressions
- Obtain a 12-lead ECG before starting care
- Begin chest compressions immediately
Correct answer: Begin chest compressions immediately
Correct answer: Begin chest compressions immediately. For an unresponsive, pulseless, non-breathing adult, high-quality chest compressions are started first under the compression-airway-breathing approach to maintain circulation. Giving breaths first, inserting an advanced airway first, or obtaining a 12-lead before starting compressions would all delay perfusion.
- During the primary assessment of a responsive adult, you note that the patient can speak only in two- to three-word phrases between breaths. What does this most strongly suggest?
- The patient has an adequate airway and breathing
- The patient has a normal level of consciousness only
- The patient is in significant respiratory distress
- The patient is hyperventilating from anxiety alone
Correct answer: The patient is in significant respiratory distress
Correct answer: The patient is in significant respiratory distress. The inability to speak in full sentences and the need to pause for breath after only a few words indicates significant respiratory distress and inadequate air movement. It does not reflect adequate breathing, it tells you more than just consciousness, and it should not be assumed to be simple anxiety.
- While performing a primary assessment, you find a patient who responds only by withdrawing from a painful pinch and does not respond to your voice. How would you classify this patient on the AVPU scale?
- Alert
- Responsive to painful stimuli
- Responsive to verbal stimuli
- Unresponsive
Correct answer: Responsive to painful stimuli
Correct answer: Responsive to painful stimuli. A patient who reacts only to a painful stimulus and not to voice is classified as P, responsive to pain, on the AVPU scale. Alert means awake and interactive, verbal means responding to voice, and unresponsive means no response to any stimulus.
- You are assessing skin during the circulation check of an adult in early shock. Which combination of skin findings is most consistent with compensated shock?
- Warm, dry, pink skin
- Flushed, hot, dry skin
- Pale, cool, clammy skin
- Jaundiced, warm skin
Correct answer: Pale, cool, clammy skin
Correct answer: Pale, cool, clammy skin. In compensated shock the body shunts blood away from the skin to vital organs, producing pale, cool, and clammy skin. Warm, dry, pink skin is normal, flushed hot dry skin suggests heat emergency or fever, and jaundice reflects liver dysfunction rather than shock perfusion changes.
- During the primary assessment, you note an unresponsive patient making a snoring sound with each breath. What is the most likely cause and immediate action?
- Fluid in the airway requiring suction
- Bronchospasm requiring a bronchodilator
- The tongue obstructing the airway requiring a manual airway maneuver
- Adequate breathing requiring no action
Correct answer: The tongue obstructing the airway requiring a manual airway maneuver
Correct answer: The tongue obstructing the airway requiring a manual airway maneuver. Snoring respirations in an unresponsive patient indicate the relaxed tongue is partially blocking the airway, which is corrected by a head-tilt, chin-lift or jaw-thrust. Gurgling rather than snoring suggests fluid needing suction, wheezing suggests bronchospasm, and the abnormal sound means breathing is not adequate.
- You are about to begin patient care after parking your ambulance at a collision. Putting on gloves and eye protection during scene size-up addresses which component of that step?
- Determining the number of patients
- Identifying the nature of illness
- Forming a general impression of the patient
- Taking standard precautions for body substance isolation
Correct answer: Taking standard precautions for body substance isolation
Correct answer: Taking standard precautions for body substance isolation. Donning gloves and eye protection during scene size-up satisfies the body substance isolation, or standard precautions, component that protects you from exposure to body fluids. Counting patients, identifying nature of illness, and forming a general impression are separate elements of size-up and assessment.
- During the disability step of the primary assessment of a trauma patient, what is the primary purpose of quickly establishing a baseline level of consciousness?
- To diagnose the exact cause of the patient's injury
- To replace the need for a full secondary assessment
- To determine the patient's blood type
- To provide a reference point for detecting changes during reassessment
Correct answer: To provide a reference point for detecting changes during reassessment
Correct answer: To provide a reference point for detecting changes during reassessment. Establishing a baseline mental status in the disability step lets you recognize improvement or deterioration when you reassess the patient later. It does not diagnose the injury cause, replace the secondary assessment, or determine blood type.
- You are assessing an alert, talking patient during the primary assessment. Why can the airway and a portion of breathing be partially evaluated by the fact that the patient is speaking clearly?
- Speech proves the patient has a normal blood pressure
- Speech confirms the patient has no internal bleeding
- Clear speech confirms the airway is open and air is moving
- Speech guarantees the oxygen saturation is above 94 percent
Correct answer: Clear speech confirms the airway is open and air is moving
Correct answer: Clear speech confirms the airway is open and air is moving. A patient who is speaking clearly must have a patent airway and enough air movement to phonate, which partially confirms airway and breathing. Speaking does not confirm a normal blood pressure, rule out internal bleeding, or guarantee a specific oxygen saturation.
- During the primary assessment, after you confirm the scene is safe and form a general impression, what is the next step in the standard sequence?
- Obtain a detailed SAMPLE history
- Assess the patient's level of consciousness
- Perform a head-to-toe secondary assessment
- Take a complete set of baseline vital signs
Correct answer: Assess the patient's level of consciousness
Correct answer: Assess the patient's level of consciousness. After forming a general impression, the primary assessment continues by determining the patient's level of consciousness before evaluating the airway, breathing, and circulation. A SAMPLE history, a head-to-toe exam, and a full set of vital signs are part of the secondary assessment that follows the primary assessment.
- You are caring for an unresponsive adult during the primary assessment and need to assess circulation. Where should you palpate for a pulse in this patient?
- The radial pulse at the wrist
- The carotid pulse in the neck
- The brachial pulse in the arm
- The dorsalis pedis pulse on the foot
Correct answer: The carotid pulse in the neck
Correct answer: The carotid pulse in the neck. For an unresponsive adult, the carotid pulse is checked because central pulses remain palpable even when peripheral perfusion is poor. The radial pulse may be absent in shock, the brachial site is preferred for infants, and the dorsalis pedis is not a reliable primary-assessment pulse check.
- During the breathing assessment of an adult, you find a respiratory rate of 28, deep labored breaths, and accessory muscle use. How should you characterize this breathing?
- Adequate breathing requiring only observation
- A normal compensatory pattern that needs no support
- Evidence that the airway is obstructed by the tongue
- Inadequate or distressed breathing requiring oxygen and close monitoring
Correct answer: Inadequate or distressed breathing requiring oxygen and close monitoring
Correct answer: Inadequate or distressed breathing requiring oxygen and close monitoring. A fast rate with labored breaths and accessory muscle use signals respiratory distress, so the patient needs supplemental oxygen and close monitoring for deterioration. It is not adequate breathing, it is not a benign normal pattern, and accessory muscle use reflects increased work of breathing rather than tongue obstruction.
- You arrive at a residence and, before exiting the ambulance, you notice downed power lines across the driveway near the patient. What does this represent in your approach to the call?
- A finding from the primary assessment of the patient
- A component of the general impression
- A reason to immediately begin CPR
- A scene safety hazard identified during scene size-up
Correct answer: A scene safety hazard identified during scene size-up
Correct answer: A scene safety hazard identified during scene size-up. Recognizing downed power lines before approaching is part of evaluating scene safety during scene size-up, and the area must be made safe before patient contact. It is not a patient assessment finding, not part of the general impression, and not an indication to begin CPR.
- During the primary assessment of a responsive medical patient, when is the appropriate time to obtain the chief complaint?
- Early in the assessment, often while forming the general impression
- After completing the full secondary assessment
- Only after baseline vital signs are recorded
- At the hospital during patient handoff
Correct answer: Early in the assessment, often while forming the general impression
Correct answer: Early in the assessment, often while forming the general impression. The chief complaint is identified early, typically as you form the general impression and speak with a responsive patient, because it focuses the rest of the assessment. Waiting until after the secondary assessment, after vitals, or until hospital handoff would delay this essential information.
- You are forming a general impression of a patient. Which three elements are you primarily evaluating in those first few seconds?
- Appearance, level of distress, and chief complaint or environment
- Blood pressure, pulse, and respirations
- Pupil size, capillary refill, and skin temperature
- Blood glucose, oxygen saturation, and temperature
Correct answer: Appearance, level of distress, and chief complaint or environment
Correct answer: Appearance, level of distress, and chief complaint or environment. The general impression is a rapid, hands-off evaluation of the patient's overall appearance, apparent level of distress, and the chief complaint or surrounding environment. Measured vital signs, pupil and capillary checks, and laboratory-type values are gathered later, not during the general impression.
- During the circulation step of the primary assessment, you check a patient's skin and find it is hot and dry. In the context of perfusion, which condition might this finding suggest?
- Early compensated hemorrhagic shock
- Adequate normal perfusion
- Hypothermia
- A heat emergency or high fever
Correct answer: A heat emergency or high fever
Correct answer: A heat emergency or high fever. Hot, dry skin during the circulation assessment can indicate a heat emergency such as heat stroke or a significant fever. Compensated hemorrhagic shock produces cool, clammy skin, normal perfusion produces warm, dry, pink skin, and hypothermia produces cold skin.
- You are performing the primary assessment on a quiet, listless toddler who does not interact with you or react to your presence. In a pediatric patient, how should this behavior be interpreted?
- As a reassuring sign of a calm, cooperative child
- As a normal finding for any sleeping child
- As a worrisome sign of a potentially serious condition
- As proof the child has an adequate airway
Correct answer: As a worrisome sign of a potentially serious condition
Correct answer: As a worrisome sign of a potentially serious condition. A child who is unusually quiet, listless, and does not respond to the environment is showing an abnormal appearance that suggests serious illness or injury. It is not reassuring, should not be dismissed as sleeping, and does not confirm an adequate airway.
- During the primary assessment of an unresponsive adult, you open the airway and then look, listen, and feel briefly while checking a pulse. What is the purpose of evaluating breathing and pulse together in this situation?
- To quickly determine the need for ventilations or CPR
- To calculate an accurate Glasgow Coma Scale score
- To estimate the total body surface area burned
- To obtain the patient's chief complaint
Correct answer: To quickly determine the need for ventilations or CPR
Correct answer: To quickly determine the need for ventilations or CPR. Simultaneously checking for normal breathing and a pulse in an unresponsive patient lets you rapidly decide whether the patient needs rescue ventilations, CPR, or other immediate intervention. It is not how a GCS score is calculated, has nothing to do with burn surface area, and does not provide a chief complaint.
- You determine that a non-breathing adult has a palpable pulse during the primary assessment. What is the appropriate immediate action?
- Provide rescue ventilations at the recommended rate
- Begin chest compressions
- Apply only a nasal cannula and continue assessing
- Withhold ventilations until vital signs are obtained
Correct answer: Provide rescue ventilations at the recommended rate
Correct answer: Provide rescue ventilations at the recommended rate. A patient who has a pulse but is not breathing is in respiratory arrest and needs rescue ventilations to maintain oxygenation while circulation continues. Chest compressions are for pulseless patients, a nasal cannula cannot ventilate an apneic patient, and ventilations must not be delayed to obtain vitals.
- During scene size-up at a motor vehicle collision, you note severe intrusion into the passenger compartment and a starred windshield. How does this information guide your primary assessment?
- It raises suspicion for serious internal injuries and spinal involvement
- It establishes the patient's exact Glasgow Coma Scale score
- It confirms the patient has no life-threatening injuries
- It eliminates the need to check the airway
Correct answer: It raises suspicion for serious internal injuries and spinal involvement
Correct answer: It raises suspicion for serious internal injuries and spinal involvement. A significant mechanism of injury such as compartment intrusion and a starred windshield heightens your index of suspicion for serious internal and spinal injuries, prompting a thorough primary assessment and spinal precautions. It does not set a GCS score, rule out life threats, or remove the need to assess the airway.
- While assessing an adult's circulation during the primary assessment, you find that the radial pulse is present and strong. What does a strong, present radial pulse generally indicate about perfusion?
- The patient is definitely in decompensated shock
- The patient has at least adequate peripheral perfusion at that moment
- The patient has a fully patent airway
- The patient must have a normal level of consciousness
Correct answer: The patient has at least adequate peripheral perfusion at that moment
Correct answer: The patient has at least adequate peripheral perfusion at that moment. A strong, palpable radial pulse indicates the patient currently has enough blood pressure and perfusion to maintain a peripheral pulse. It does not indicate decompensated shock, does not confirm airway patency, and does not establish level of consciousness.
- You are deciding the order of interventions during the primary assessment of a critical patient. According to the principle of treating life threats as they are found, what should you do when you identify an immediate life threat?
- Note it and address it during the secondary assessment
- Stop and correct the life threat before moving on
- Complete all of airway, breathing, and circulation before treating anything
- Defer treatment until you reach the hospital
Correct answer: Stop and correct the life threat before moving on
Correct answer: Stop and correct the life threat before moving on. The primary assessment follows a treat-as-you-go principle, so any immediate life threat to airway, breathing, or circulation is corrected at the moment it is found before continuing. Deferring it to the secondary assessment, finishing the entire sequence first, or waiting until the hospital would all allow a correctable life threat to harm the patient.
- During the primary assessment of an unresponsive adult, you find inadequate breathing and prepare to ventilate. What is the most reliable indicator that your bag-valve-mask ventilations are effective?
- A loud sound coming from the mask seal
- Visible, adequate chest rise with each ventilation
- Gastric distention developing in the abdomen
- Increasing resistance felt while squeezing the bag
Correct answer: Visible, adequate chest rise with each ventilation
Correct answer: Visible, adequate chest rise with each ventilation. Adequate, symmetrical chest rise with each squeeze of the bag confirms that air is reaching the lungs and ventilations are effective. A loud mask sound suggests a leak, gastric distention indicates air entering the stomach, and increasing resistance suggests obstruction or poor technique.
- You are caring for a patient in shock during the primary assessment whose mental status has declined from anxious to confused, with a weak pulse and dropping blood pressure. Which stage of shock do these findings indicate?
- Decompensated shock
- Compensated shock
- No shock present
- Psychogenic shock only
Correct answer: Decompensated shock
Correct answer: Decompensated shock. A falling blood pressure together with worsening mental status and a weakening pulse marks decompensated shock, in which the body can no longer maintain perfusion. Compensated shock maintains a normal blood pressure, the findings clearly indicate shock is present, and psychogenic shock refers to fainting rather than this progressive collapse.
- During the primary assessment, you suspect a patient has a spinal injury after a fall. While maintaining manual in-line stabilization, you must still open the airway. Which approach correctly balances both needs?
- Use the jaw-thrust while a partner maintains in-line stabilization
- Use the head-tilt, chin-lift to ensure a fully open airway
- Delay opening the airway until the patient is fully immobilized
- Turn the patient prone to allow secretions to drain
Correct answer: Use the jaw-thrust while a partner maintains in-line stabilization
Correct answer: Use the jaw-thrust while a partner maintains in-line stabilization. The jaw-thrust opens the airway without moving the cervical spine and can be performed while manual in-line stabilization is maintained, addressing both the airway and the suspected spinal injury. The head-tilt, chin-lift extends the neck, delaying the airway risks asphyxia, and turning the patient prone would endanger the spine and is not an airway maneuver.
- Using the Pediatric Assessment Triangle (PAT) from across the room, which three components do you evaluate before laying hands on the child?
- Airway, blood pressure, and pulse rate
- Appearance, work of breathing, and circulation to the skin
- Pupils, capillary refill, and lung sounds
- Mental status, temperature, and oxygen saturation
Correct answer: Appearance, work of breathing, and circulation to the skin
Appearance, work of breathing, and circulation to the skin are the three sides of the Pediatric Assessment Triangle. The PAT is a hands-off, across-the-room tool used at the start of the primary assessment to form a rapid general impression of how sick a child is; the other options require physically touching the patient or equipment and are not part of the triangle.
- On the 'Appearance' side of the Pediatric Assessment Triangle, the TICLS (tickles) mnemonic is used. What does TICLS stand for?
- Tone, Interactiveness, Consolability, Look/gaze, and Speech/cry
- Temperature, Intake, Color, Level of pain, and Skin
- Trauma, Infection, Circulation, Lungs, and Saturation
- Tone, Interactiveness, Consolability, Look/gaze, and Speech/cry quality
Correct answer: Tone, Interactiveness, Consolability, Look/gaze, and Speech/cry quality
The correct answer describes TICLS as Tone, Interactiveness, Consolability, Look/gaze, and Speech/cry quality. This mnemonic guides assessment of the Appearance side of the Pediatric Assessment Triangle, helping the EMT judge a child's neurologic and overall status quickly without equipment.
- During scene size-up immediately before the primary assessment, which determination most directly shapes how the primary assessment will be conducted?
- Whether the patient is a medical or trauma patient and the mechanism of injury or nature of illness
- Whether the patient has private insurance
- The patient's home address and phone number
- The estimated time of the next available ambulance
Correct answer: Whether the patient is a medical or trauma patient and the mechanism of injury or nature of illness
Determining whether the patient is a medical or trauma patient, along with the mechanism of injury or nature of illness, most directly shapes the primary assessment. This information from scene size-up tells the EMT whether to suspect spinal injury, how aggressively to look for life threats, and which assessment sequence to prioritize.
- An EMT is forming a general impression of a 2-year-old who is sitting up, playing, with pink skin and no increased work of breathing. Using the Pediatric Assessment Triangle, this child is best characterized as:
- In respiratory failure requiring immediate ventilation
- In cardiopulmonary failure
- In decompensated shock
- Stable, with all three sides of the triangle intact
Correct answer: Stable, with all three sides of the triangle intact
This child is best characterized as stable with all three sides of the triangle intact. Normal appearance (playing, interactive), normal work of breathing (no retractions or abnormal sounds), and normal circulation to the skin (pink) indicate none of the three PAT sides is abnormal, so no immediate life threat is identified.
- When forming an across-the-room general impression of an adult, which combination of observations is most useful before any hands-on assessment?
- Exact blood pressure, blood glucose, and 12-lead reading
- Insurance status, next of kin, and preferred hospital
- Past surgical history, allergies, and current medications
- Age, position/posture, level of distress, and skin color
Correct answer: Age, position/posture, level of distress, and skin color
Age, position/posture, level of distress, and skin color form the most useful across-the-room general impression. These observable cues require no equipment and are gathered in the first seconds to gauge how sick the patient appears and to prioritize the rest of the primary assessment; the other choices require history-taking or devices.
- You find an adult lying in a tripod position, leaning forward on outstretched arms. During your general impression, this posture most strongly suggests:
- Acute abdominal pain only
- A normal, comfortable resting position
- Severe respiratory distress
- Adequate perfusion and no immediate concern
Correct answer: Severe respiratory distress
The tripod position most strongly suggests severe respiratory distress. Patients instinctively assume this posture to maximize accessory muscle use and air movement, so during the general impression it alerts the EMT to a likely breathing life threat before formally assessing the airway and breathing.
- In a responsive adult, what is the simplest single finding during the airway portion of the primary assessment that confirms the airway is currently open?
- A palpable radial pulse
- Pink, warm skin
- The patient speaking clearly in a normal voice
- Equal pupil size
Correct answer: The patient speaking clearly in a normal voice
The patient speaking clearly in a normal voice confirms the airway is currently open. Phonation requires air to move past the vocal cords, so clear speech tells the EMT the airway is patent at that moment; pulse, skin, and pupils relate to circulation or neurologic status, not airway patency.
- During the primary assessment of an unresponsive non-trauma adult, which manual maneuver is preferred to open the airway?
- Jaw-thrust without head movement
- Head-tilt, chin-lift
- Placing the patient in a prone position
- Flexing the neck forward toward the chest
Correct answer: Head-tilt, chin-lift
Head-tilt, chin-lift is preferred for an unresponsive patient with no suspected spinal injury. It lifts the tongue off the posterior pharynx most effectively; the jaw-thrust is reserved for suspected spinal injury, and prone positioning or neck flexion would obstruct rather than open the airway.
- An EMT decides that an unresponsive patient needs an airway adjunct during the primary assessment. Which finding makes a nasopharyngeal airway preferable to an oropharyngeal airway?
- The patient has an intact gag reflex
- The patient has obvious facial trauma with possible basilar skull fracture
- The patient is in cardiac arrest
- The patient is completely areflexic
Correct answer: The patient has an intact gag reflex
An intact gag reflex makes a nasopharyngeal airway preferable. The NPA is generally tolerated in patients who still gag, whereas an OPA would trigger gagging and vomiting; severe midface or basilar skull injury is actually a contraindication to the NPA, not an indication.
- While assessing breathing during the primary assessment, an EMT notes intercostal and suprasternal retractions in an adult. These findings indicate:
- Normal, effortless breathing
- Adequate tidal volume requiring no intervention
- A patent and unobstructed airway with no concern
- Increased work of breathing
Correct answer: Increased work of breathing
Intercostal and suprasternal retractions indicate increased work of breathing. The patient is recruiting accessory muscles and pulling in soft tissues to move air, signaling respiratory difficulty that must be addressed during the breathing step of the primary assessment, regardless of how fast the patient is breathing.
- When evaluating the adequacy of breathing in the primary assessment, which trio of factors should the EMT judge together?
- Blood glucose, oxygen saturation, and end-tidal CO2 only
- Pulse rate, blood pressure, and temperature
- Pupil size, skin turgor, and capillary refill
- Rate, depth (tidal volume), and effort
Correct answer: Rate, depth (tidal volume), and effort
Rate, depth (tidal volume), and effort must be judged together to determine breathing adequacy. A normal rate with shallow depth or excessive effort can still represent inadequate ventilation, so the EMT cannot rely on rate alone; the other options assess circulation or use devices not central to the basic breathing check.
- An adult is breathing 8 times per minute with very shallow chest rise during your primary assessment. What is the most appropriate immediate action?
- Begin assisting ventilations with a bag-valve mask
- Apply a nasal cannula at 2 L/min and continue assessment
- Encourage the patient to take slow, deep breaths
- Place the patient in a position of comfort and reassess in 5 minutes
Correct answer: Begin assisting ventilations with a bag-valve mask
Begin assisting ventilations with a bag-valve mask. A rate of 8 with shallow depth produces inadequate minute ventilation, a breathing life threat identified in the primary assessment; passive oxygen, coaching, or delayed reassessment will not correct inadequate tidal volume in a hypoventilating patient.
- During the circulation step of the primary assessment on a responsive adult, where should the EMT typically check the pulse first?
- Radial artery
- Carotid artery
- Femoral artery
- Dorsalis pedis artery
Correct answer: Radial artery
The radial artery is checked first in a responsive adult. It is easily accessible and a palpable radial pulse also gives a rough sense of perfusion; the carotid is reserved primarily for unresponsive patients when peripheral pulses may be absent, and the femoral and pedal sites are not routine first checks.
- In an unresponsive adult during the primary assessment, which pulse should be palpated to confirm circulation?
- Radial pulse only
- Brachial pulse
- Carotid pulse
- Posterior tibial pulse
Correct answer: Carotid pulse
The carotid pulse is palpated in an unresponsive adult. Central pulses persist longer than peripheral ones when perfusion drops, so the carotid reliably detects a heartbeat; the brachial site is used for infants, and radial or pedal pulses may be absent in a poorly perfusing unresponsive adult.
- When checking circulation in an unresponsive infant during the primary assessment, which pulse site is recommended?
- Carotid pulse
- Radial pulse
- Brachial pulse
- Femoral pulse only
Correct answer: Brachial pulse
The brachial pulse is recommended for an unresponsive infant. An infant's short, chubby neck makes the carotid difficult and risky to palpate, so the brachial artery in the upper arm is the standard site to confirm a pulse during the circulation check.
- During the circulation portion of the primary assessment, an EMT identifies severe external arterial bleeding. According to current EMS guidelines, what is the preferred first action to control life-threatening extremity hemorrhage?
- Elevation of the extremity alone
- Application of a cold pack to the wound
- Direct pressure, escalating to a tourniquet if pressure fails or bleeding is severe
- Pressure point compression as the sole method
Correct answer: Direct pressure, escalating to a tourniquet if pressure fails or bleeding is severe
Direct pressure, escalating to a tourniquet if pressure fails or the bleeding is severe, is the preferred approach. Current guidelines emphasize rapid, firm direct pressure and early tourniquet use for life-threatening extremity hemorrhage; elevation, cold packs, and isolated pressure points are not reliable for controlling massive arterial bleeding.
- An EMT presses on a patient's forehead skin during the circulation check and notes it is diaphoretic and cool. In the context of the primary assessment, these skin findings most likely reflect:
- Adequate perfusion and a calm patient
- Heat stroke with hot, dry skin
- Sympathetic compensation for poor perfusion (early shock)
- A localized allergic reaction
Correct answer: Sympathetic compensation for poor perfusion (early shock)
Cool, diaphoretic skin most likely reflects sympathetic compensation for poor perfusion, an early sign of shock. The body shunts blood from the skin and activates sweat glands, producing cool, clammy skin; this is the opposite of heat stroke's hot, dry skin and signals a circulation problem to address.
- The widely taught primary assessment sequence in EMS is sometimes summarized by a mnemonic. After ensuring scene safety and forming a general impression, which ordered sequence reflects the standard ABC priority for most patients?
- Circulation, then Breathing, then Airway
- Circulation, then Airway, then Breathing
- Breathing, then Circulation, then Airway
- Airway, then Breathing, then Circulation
Correct answer: Airway, then Breathing, then Circulation
Airway, then Breathing, then Circulation is the standard ABC priority for most patients. After confirming the airway is open, the EMT ensures adequate breathing, then evaluates and supports circulation; this ordering ensures the most rapidly fatal problems are addressed in sequence.
- For a patient with severe life-threatening external hemorrhage, many systems now teach an 'X' placed before ABC. What does this 'X-ABC' sequence prioritize?
- X-ray imaging before any treatment
- Extricating the patient before assessment
- Examining the pupils before the airway
- Controlling massive (exsanguinating) hemorrhage before airway and breathing
Correct answer: Controlling massive (exsanguinating) hemorrhage before airway and breathing
The 'X' prioritizes controlling massive (exsanguinating) hemorrhage before airway and breathing. When a patient is rapidly bleeding to death, stopping that hemorrhage immediately takes precedence because the patient can exsanguinate faster than an airway problem would prove fatal.
- After completing the primary assessment and identifying a critical patient, how does the primary assessment most directly influence the EMT's next decision?
- It drives the transport priority decision (load-and-go versus stay-and-treat)
- It determines the patient's billing category
- It establishes the patient's long-term prognosis
- It selects the hospital's room assignment
Correct answer: It drives the transport priority decision (load-and-go versus stay-and-treat)
The primary assessment most directly drives the transport priority decision. Finding life threats to airway, breathing, or circulation flags the patient as high priority, prompting rapid transport with treatment en route, whereas a stable primary assessment allows more on-scene evaluation.
- An EMT completes a primary assessment, manages identified life threats, and then must decide when to repeat the assessment. For an unstable patient, the primary/ongoing reassessment should generally be repeated at least every:
- 15 minutes
- 5 minutes
- 30 minutes
- 60 minutes
Correct answer: 5 minutes
An unstable patient should be reassessed at least every 5 minutes. Frequent reassessment of mental status, airway, breathing, and circulation detects deterioration quickly; stable patients are typically reassessed every 15 minutes, but unstable patients require the shorter 5-minute interval.
- During the primary assessment of an unresponsive adult who is not breathing, after the airway is opened the EMT should next:
- Provide rescue ventilations and assess for a pulse
- Obtain a full set of vital signs first
- Begin a detailed head-to-toe exam
- Gather a SAMPLE history from bystanders
Correct answer: Provide rescue ventilations and assess for a pulse
The EMT should provide rescue ventilations and assess for a pulse. In an apneic patient, supporting ventilation and confirming circulation are the immediate life-saving steps of the primary assessment; detailed exams, full vitals, and history-taking belong to later phases after life threats are managed.
- An EMT is performing the primary assessment on a patient with audible gurgling respirations. Which intervention should be performed immediately to protect the airway?
- Insert an oropharyngeal airway without clearing the airway
- Increase the ventilation rate
- Apply a non-rebreather mask and continue
- Suction the airway
Correct answer: Suction the airway
Suction the airway immediately. Gurgling indicates fluid (secretions, blood, or vomitus) in the airway, and suctioning removes it to prevent aspiration; placing an airway adjunct or applying oxygen over a fluid-filled airway, or ventilating harder, would push fluid into the lungs.
- While assessing an unresponsive patient's breathing, the EMT observes occasional gasping, irregular respirations with long pauses. These agonal respirations should be treated as:
- Adequate breathing requiring only oxygen by cannula
- A sign of improving respiratory status
- Inadequate or absent breathing requiring assisted ventilation
- Normal sleep breathing
Correct answer: Inadequate or absent breathing requiring assisted ventilation
Agonal respirations should be treated as inadequate or absent breathing requiring assisted ventilation. These ineffective gasps do not move enough air to sustain life and often precede or accompany cardiac arrest, so the EMT must ventilate rather than assume the patient is breathing adequately.
- An EMT forms a general impression that a patient 'looks sick' but cannot yet name the problem. What is the appropriate role of this gut-level impression in the primary assessment?
- It replaces the need to assess airway, breathing, and circulation
- It heightens urgency and guides priorities but must be confirmed by the systematic ABC assessment
- It should be ignored unless vital signs are abnormal
- It establishes the final field diagnosis
Correct answer: It heightens urgency and guides priorities but must be confirmed by the systematic ABC assessment
The gut-level general impression heightens urgency and guides priorities but must be confirmed by the systematic ABC assessment. A 'sick' impression alerts the EMT to move quickly and look hard for life threats, yet it does not substitute for the structured airway, breathing, and circulation checks.
- During the primary assessment of a trauma patient with a suspected spinal injury, how should the airway be opened?
- Head-tilt, chin-lift
- Modified jaw-thrust with manual in-line stabilization of the head and neck
- Hyperextension of the neck
- Turning the head fully to one side
Correct answer: Modified jaw-thrust with manual in-line stabilization of the head and neck
A modified jaw-thrust with manual in-line stabilization opens the airway without moving the cervical spine. This technique displaces the jaw forward to lift the tongue while keeping the head and neck neutral; head-tilt, hyperextension, or turning the head could worsen a spinal injury.
- The primary assessment is best described as a process designed to:
- Obtain a complete past medical history
- Document insurance and demographic information
- Rapidly identify and treat immediate threats to life
- Perform a detailed head-to-toe physical exam
Correct answer: Rapidly identify and treat immediate threats to life
The primary assessment is designed to rapidly identify and treat immediate threats to life. Its focus is the airway, breathing, circulation, and gross neurologic status; detailed history, head-to-toe exams, and paperwork occur later in the patient assessment after life threats are managed.
- An EMT establishes that an unresponsive adult patient has a patent airway and is breathing adequately. During the circulation check, the radial pulse is absent but the carotid is present. What does this most likely indicate?
- Normal perfusion with no concern
- Significant hypoperfusion, since peripheral pulses are lost before central pulses
- A purely neurologic problem with no circulatory issue
- An equipment error only
Correct answer: Significant hypoperfusion, since peripheral pulses are lost before central pulses
An absent radial pulse with a present carotid pulse most likely indicates significant hypoperfusion. As blood pressure and perfusion fall, peripheral pulses disappear before central ones, so this finding during the circulation check warns the EMT that the patient is poorly perfused and likely in shock.
- When using the AVPU scale during the primary assessment, a patient who responds only when you pinch the trapezius muscle is classified as:
- Alert
- Responsive to painful stimulus (P)
- Responsive to verbal stimulus (V)
- Unresponsive (U)
Correct answer: Responsive to painful stimulus (P)
A patient who responds only to a painful stimulus such as a trapezius pinch is classified as P (responsive to pain). The patient does not react to voice but does react to noxious stimulation, placing them below Verbal and above Unresponsive on the AVPU scale used in the primary assessment.
- During the breathing assessment of the primary survey, an EMT notes a patient speaking in only one- or two-word bursts between breaths. This finding indicates:
- Significant respiratory distress affecting the ability to move air and speak
- Normal, unlabored breathing
- A purely psychological problem
- An open, completely unobstructed airway with adequate ventilation
Correct answer: Significant respiratory distress affecting the ability to move air and speak
One- to two-word dyspnea indicates significant respiratory distress. The patient cannot sustain enough airflow to speak a full sentence, signaling inadequate or labored breathing that must be supported during the primary assessment; the inability to complete sentences is a key red flag, not a normal or psychological finding.
- An EMT identifies a sucking chest wound while assessing breathing during the primary survey. Why is this considered a primary-assessment life threat rather than a later finding?
- It only affects appearance and cosmetics
- It directly impairs breathing and can rapidly compromise ventilation and circulation
- It is unrelated to airway, breathing, or circulation
- It is always painless and stable
Correct answer: It directly impairs breathing and can rapidly compromise ventilation and circulation
An open (sucking) chest wound directly impairs breathing and can rapidly compromise ventilation and circulation, making it a primary-assessment life threat. Air entering the pleural space prevents normal lung expansion and may progress to tension physiology, so it must be detected and sealed during the breathing step rather than deferred.
- During the primary assessment, an EMT must rapidly judge a patient's mental status before performing a detailed neuro exam. Which tool is designed for this rapid initial check?
- The AVPU scale
- The APGAR score
- The Rule of Nines
- The OPQRST mnemonic
Correct answer: The AVPU scale
The AVPU scale is designed for the rapid initial mental-status check in the primary assessment. It quickly categorizes the patient as Alert, Verbal, Painful, or Unresponsive; APGAR scores newborns, Rule of Nines estimates burn area, and OPQRST explores pain history later in assessment.
- You arrive at an unresponsive adult. Before approaching to begin the primary assessment, what must be confirmed first?
- The patient's medication list
- The nearest trauma center's bed availability
- The patient's blood pressure
- Scene safety and appropriate standard (BSI) precautions
Correct answer: Scene safety and appropriate standard (BSI) precautions
Scene safety and appropriate standard (BSI) precautions must be confirmed first. Ensuring the scene is safe and donning protective equipment protects the EMT before any patient contact; assessment and treatment, including the primary assessment, only begin once the EMT can safely approach.
- An EMT is determining whether a responsive adult's breathing is adequate during the primary assessment. Which finding is most consistent with adequate breathing?
- Cyanosis with shallow, irregular breaths
- Nasal flaring with one-word answers
- Regular rate, adequate chest rise, and the ability to speak full sentences
- Tripod positioning with audible wheezing at rest
Correct answer: Regular rate, adequate chest rise, and the ability to speak full sentences
A regular rate, adequate chest rise, and the ability to speak full sentences are most consistent with adequate breathing. These indicate sufficient rate and tidal volume with normal effort; nasal flaring, cyanosis, shallow irregular breaths, and tripod positioning all signal inadequate or distressed breathing.
- During the primary assessment, the EMT notes a patient is cyanotic around the lips and nail beds. What does central cyanosis most directly indicate?
- Adequate oxygenation
- Mild dehydration only
- Inadequate oxygenation of the blood
- A normal finding in cold weather with no clinical significance
Correct answer: Inadequate oxygenation of the blood
Central cyanosis most directly indicates inadequate oxygenation of the blood. Bluish discoloration of the lips and nail beds reflects a high level of deoxygenated hemoglobin, a breathing/oxygenation life threat the EMT must address with airway management and oxygen during the primary assessment.
- An EMT is performing a primary assessment on a conscious choking adult who suddenly cannot speak, cough, or breathe. Within the airway step, this presentation requires:
- Immediate abdominal thrusts to relieve the complete obstruction
- Encouraging the patient to keep coughing
- Applying a non-rebreather mask and observing
- Obtaining a full SAMPLE history before acting
Correct answer: Immediate abdominal thrusts to relieve the complete obstruction
Immediate abdominal thrusts are required to relieve the complete obstruction. The inability to speak, cough, or breathe signals a complete airway obstruction discovered in the airway step of the primary assessment; coughing is encouraged only for partial obstruction, and delaying for oxygen or history would be fatal.
- While forming a general impression, an EMT classifies a patient as a high-priority transport based on the primary assessment. Which finding alone would justify this high-priority classification?
- A patient who is alert and ambulatory with a minor laceration
- A patient requesting transport for a routine checkup
- A patient with a stubbed toe and normal vitals
- A patient with an altered mental status and inadequate breathing
Correct answer: A patient with an altered mental status and inadequate breathing
Altered mental status with inadequate breathing alone justifies a high-priority classification. Compromise of the brain's oxygenation and of breathing represents an immediate threat to life identified in the primary assessment, mandating rapid transport, while the other patients show no life threats.
- An EMT assessing circulation in a child presses a fingernail and counts how long color takes to return. A capillary refill time greater than 2 seconds in a child suggests:
- Excellent peripheral perfusion
- Delayed perfusion that may indicate shock
- A normal finding requiring no further concern
- An airway obstruction
Correct answer: Delayed perfusion that may indicate shock
A capillary refill time greater than 2 seconds in a child suggests delayed perfusion that may indicate shock. Sluggish refill reflects poor peripheral blood flow, a useful circulation indicator in pediatric patients during the primary assessment, prompting the EMT to look further for signs of hypoperfusion.
- When the primary assessment reveals that a patient's airway, breathing, and circulation are all intact and the patient is alert, the EMT should:
- Immediately discontinue all assessment
- Proceed to the appropriate history and secondary assessment while continuing to monitor
- Skip transport altogether
- Repeat the primary assessment continuously and do nothing else
Correct answer: Proceed to the appropriate history and secondary assessment while continuing to monitor
The EMT should proceed to the appropriate history and secondary assessment while continuing to monitor. Once the primary assessment finds no immediate life threats, the EMT moves to gathering history and a focused or detailed exam, but ongoing monitoring continues to catch any change in the patient's condition.
- During the primary assessment, why must the EMT correct each life threat as it is found rather than waiting until the entire assessment is complete?
- Because untreated airway, breathing, or circulation problems can cause death within minutes
- To save time on documentation later
- Because protocols forbid completing the assessment
- Because the secondary assessment must always come first
Correct answer: Because untreated airway, breathing, or circulation problems can cause death within minutes
Life threats must be corrected as found because untreated airway, breathing, or circulation problems can cause death within minutes. The 'treat as you go' principle of the primary assessment means a blocked airway is opened, inadequate breathing is supported, and major bleeding is controlled immediately, not deferred.
- During the breathing portion of the primary assessment on an unresponsive adult, you observe occasional, slow, irregular gasping movements roughly every 10 seconds with no effective chest rise. How should you interpret and act on this finding?
- It is adequate breathing, so apply oxygen by nasal cannula and continue assessment
- These are agonal respirations; treat the patient as not breathing and begin positive-pressure ventilation or CPR as indicated
- It is a normal compensatory pattern that should be monitored without intervention
- It indicates an upper airway obstruction, so perform abdominal thrusts immediately
Correct answer: These are agonal respirations; treat the patient as not breathing and begin positive-pressure ventilation or CPR as indicated
The correct interpretation is that these are agonal respirations, and the patient should be treated as not breathing, with positive-pressure ventilation or CPR begun as indicated. Agonal gasps are ineffective, dying reflex movements that do not move meaningful air and must never be mistaken for adequate breathing during the primary assessment. Applying only a nasal cannula or simply monitoring would dangerously delay life-saving ventilations, since this patient is functionally apneic. The pattern is not a sign of airway obstruction by a foreign body, so abdominal thrusts are not indicated; the priority is recognizing inadequate breathing and immediately supporting ventilation.
- During the secondary assessment, what does the 'P' in the OPQRST mnemonic prompt the EMT to ask about?
- The patient's past medical history
- The pertinent negatives the patient denies
- The patient's current prescriptions
- What provokes or palliates the symptom
Correct answer: What provokes or palliates the symptom
Correct answer: What provokes or palliates the symptom. In OPQRST, 'P' stands for Provocation/Palliation, prompting the EMT to ask what makes the complaint better or worse. The mnemonic is used during the history portion of the secondary assessment to characterize a chief complaint such as pain. Onset, Quality, Region/Radiation, Severity, and Time complete the tool.
- When gathering a SAMPLE history during the secondary assessment, what does the 'E' represent?
- Events leading up to the illness or injury
- Estimated time of symptom onset
- Existing allergies to medications
- Emergency contact information
Correct answer: Events leading up to the illness or injury
Correct answer: Events leading up to the illness or injury. In the SAMPLE history, 'E' stands for Events leading up to the present complaint, helping the EMT understand the context and mechanism. SAMPLE also covers Signs/Symptoms, Allergies, Medications, Past pertinent history, and Last oral intake, and it is collected during the secondary assessment.
- After completing the primary assessment on a responsive medical patient, the secondary assessment generally begins with which step?
- A rapid full-body trauma exam
- Immediate transport without further evaluation
- A history of the present illness and SAMPLE history
- Repeating the airway, breathing, and circulation checks only
Correct answer: A history of the present illness and SAMPLE history
Correct answer: A history of the present illness and SAMPLE history. For a responsive medical patient, the secondary assessment is typically history-driven, beginning with the history of present illness (often using OPQRST) and the SAMPLE history, followed by a focused physical exam guided by the chief complaint. This contrasts with the trauma approach, which emphasizes a physical exam first.
- During a focused secondary assessment, the EMT presses on the abdomen and feels firm, board-like resistance. This finding is best described as:
- Crepitus
- Jugular venous distention
- Subcutaneous emphysema
- Guarding or rigidity
Correct answer: Guarding or rigidity
Correct answer: Guarding or rigidity. A firm, board-like abdomen detected on palpation during the secondary assessment is described as guarding or rigidity and suggests peritoneal irritation or internal injury. Crepitus refers to a grating sensation over fractured bone, while subcutaneous emphysema is air trapped under the skin.
- The DCAP-BTLS mnemonic used during the secondary assessment of trauma patients is a checklist for:
- Signs of inadequate breathing
- Findings to look and feel for at each body region
- Steps for spinal motion restriction
- Components of a baseline set of vital signs
Correct answer: Findings to look and feel for at each body region
Correct answer: Findings to look and feel for at each body region. DCAP-BTLS reminds the EMT to inspect and palpate each region for Deformities, Contusions, Abrasions, Punctures/penetrations, Burns, Tenderness, Lacerations, and Swelling. It structures the physical exam portion of the secondary assessment in trauma patients.
- While taking vital signs during the secondary assessment, an EMT documents that the pupils are equal and reactive to light. The standard abbreviation for normal pupil findings is:
Correct answer: PERRL
Correct answer: PERRL. Pupils that are Equal, Round, and Reactive to Light are documented as PERRL, a normal finding assessed during the secondary assessment. AVPU describes level of responsiveness, GCS is the Glasgow Coma Scale, and BSI refers to body substance isolation precautions.
- Which assessment technique involves listening to breath sounds with a stethoscope during the secondary assessment?
- Palpation
- Percussion
- Auscultation
- Inspection
Correct answer: Auscultation
Correct answer: Auscultation. Auscultation is the act of listening, typically with a stethoscope, to sounds such as breath sounds or a blood pressure during the secondary assessment. Palpation is examination by touch, inspection is visual examination, and percussion involves tapping to assess underlying structures.
- When obtaining a blood pressure by palpation during the secondary assessment, the EMT is able to determine:
- Only the systolic pressure
- Only the diastolic pressure
- Both systolic and diastolic pressures
- The mean arterial pressure directly
Correct answer: Only the systolic pressure
Correct answer: Only the systolic pressure. The palpation method detects the systolic pressure as the point at which the radial pulse returns while deflating the cuff; the diastolic pressure cannot be obtained by palpation. Auscultation with a stethoscope is required to capture both systolic and diastolic readings.
- An EMT lightly drags a gloved hand behind the supine patient's torso during the secondary assessment to check the back without rolling them excessively. This is primarily to detect:
- Pupil reactivity
- Capillary refill time
- Skin temperature trends over time
- Hidden bleeding, wounds, or deformities
Correct answer: Hidden bleeding, wounds, or deformities
Correct answer: Hidden bleeding, wounds, or deformities. Sweeping a hand along the posterior body during the secondary assessment allows the EMT to feel for concealed bleeding, wounds, or deformities that are not visible from the front. Capillary refill and pupil checks are separate assessment steps.
- During the secondary assessment, assessing distal pulse, motor function, and sensation in an injured extremity is commonly abbreviated as:
- PMS or CMS checks
- OPQRST
- DCAP-BTLS
- SAMPLE
Correct answer: PMS or CMS checks
Correct answer: PMS or CMS checks. Evaluating Pulse, Motor, and Sensation (also called Circulation, Motor, Sensation) distal to an injury during the secondary assessment confirms neurovascular status of the limb. OPQRST and SAMPLE are history tools, and DCAP-BTLS is a physical-exam inspection checklist.
- A baseline set of vital signs obtained during the secondary assessment is most valuable because it:
- Replaces the need to reassess the patient en route
- Determines the patient's exact diagnosis
- Provides a reference point to identify trends and changes over time
- Eliminates the need for a SAMPLE history
Correct answer: Provides a reference point to identify trends and changes over time
Correct answer: Provides a reference point to identify trends and changes over time. A baseline set of vitals taken during the secondary assessment lets the EMT recognize improvement or deterioration when vitals are repeated. It does not replace ongoing reassessment, establish a diagnosis, or eliminate the need for a history.
- When deciding between a rapid full-body exam and a focused physical exam during the secondary assessment of a trauma patient, the EMT should base the choice primarily on the:
- Patient's age
- Mechanism of injury and whether it is significant
- Time of day
- Patient's insurance status
Correct answer: Mechanism of injury and whether it is significant
Correct answer: Mechanism of injury and whether it is significant. A significant mechanism of injury directs the EMT to perform a rapid full-body trauma exam, while an isolated injury with a non-significant mechanism warrants a focused exam of the affected area. Age, time, and administrative factors do not drive this clinical decision.
- An EMT is deciding the transport destination for a patient with a suspected ST-elevation myocardial infarction (STEMI). Which factor should most influence the choice of receiving facility?
- Whether the hospital has percutaneous coronary intervention (PCI) capability
- Whether the hospital is the closest emergency department
- Whether the patient has previously been treated there
- Whether the hospital has the shortest wait time in triage
Correct answer: Whether the hospital has percutaneous coronary intervention (PCI) capability
Correct answer: Whether the hospital has percutaneous coronary intervention (PCI) capability. Explanation: Definitive treatment for STEMI is rapid reperfusion, so a STEMI patient should be transported to a PCI-capable center even if it is not the nearest hospital. Choosing simply the closest ED, a familiar hospital, or one with the shortest triage wait can delay the cardiac catheterization that restores coronary blood flow and limits infarct size.
- An EMT is treating a responsive adult who is choking and can no longer speak, cough, or breathe. What is the most appropriate immediate treatment?
- Encourage the patient to keep coughing forcefully
- Perform abdominal thrusts until the object is expelled or the patient becomes unresponsive
- Perform a blind finger sweep of the mouth
- Give the patient sips of water to wash the object down
Correct answer: Perform abdominal thrusts until the object is expelled or the patient becomes unresponsive
Correct answer: Perform abdominal thrusts until the object is expelled or the patient becomes unresponsive. Explanation: A responsive adult with a complete (severe) airway obstruction who cannot speak, cough, or breathe needs abdominal thrusts to generate the pressure that dislodges the object. Encouraging coughing only helps a partial obstruction, blind finger sweeps can push the object deeper, and giving water risks worsening the obstruction or aspiration.
- An EMT is preparing to transport a patient who is showing signs of hypovolemic shock from internal bleeding. Which treatment priority best improves the patient's outcome?
- Elevating the head of the stretcher to reduce cerebral pressure
- Staying on scene to attempt repeated IV placement until two lines are established
- Rapid transport to a surgical facility while maintaining warmth and oxygenation
- Withholding oxygen to avoid masking changes in mental status
Correct answer: Rapid transport to a surgical facility while maintaining warmth and oxygenation
Correct answer: Rapid transport to a surgical facility while maintaining warmth and oxygenation. Explanation: Internal hemorrhage cannot be controlled in the field, so definitive care is surgical and the priority is prompt transport while keeping the patient warm and oxygenated. Delaying on scene for multiple IV attempts wastes critical time, head elevation can reduce cerebral perfusion in shock, and oxygen should never be withheld from a shock patient.
- An EMT is caring for a conscious adult with hypoperfusion (shock) and no suspected spinal injury or breathing difficulty. How should the patient be positioned?
- In the Trendelenburg position with legs raised above the head of the bed
- Sitting fully upright in a chair
- Prone with the head turned to the side
- Supine, kept flat and warm
Correct answer: Supine, kept flat and warm
Correct answer: Supine, kept flat and warm. Explanation: Current guidance positions a shock patient supine and flat while preventing heat loss, as routine Trendelenburg or leg elevation has not been shown to improve outcomes and can impair breathing. Sitting upright reduces cerebral perfusion, and the prone position is inappropriate for an awake patient who needs airway and breathing monitoring.
- An EMT is treating a patient with a severe extremity hemorrhage that is not controlled by direct pressure. What is the next most appropriate treatment?
- Apply a commercial tourniquet proximal to the wound and tighten until bleeding stops
- Elevate the limb and wait several minutes before reassessing
- Apply pressure to a proximal pressure point only
- Loosen the dressing periodically to allow circulation
Correct answer: Apply a commercial tourniquet proximal to the wound and tighten until bleeding stops
Correct answer: Apply a commercial tourniquet proximal to the wound and tighten until bleeding stops. Explanation: When direct pressure fails to control life-threatening extremity bleeding, a tourniquet placed proximal to the wound and tightened until hemorrhage stops is the indicated next step. Elevation and pressure points are no longer relied upon as primary measures, and loosening a hemorrhage dressing reintroduces dangerous blood loss.
- An EMT applies a tourniquet to control bleeding. Which action regarding the device is most appropriate before and during transport?
- Loosen the tourniquet every five minutes to restore circulation
- Note and document the time the tourniquet was applied and leave it in place
- Cover the tourniquet with a bandage so it is not visible to the hospital staff
- Remove the tourniquet once a pressure dressing is applied
Correct answer: Note and document the time the tourniquet was applied and leave it in place
Correct answer: Note and document the time the tourniquet was applied and leave it in place. Explanation: Once a tourniquet successfully controls bleeding, the EMT should record the application time and leave the device on, allowing the receiving facility to manage removal. Periodically loosening it restarts hemorrhage, concealing it can lead to dangerous oversight, and field removal of an effective tourniquet is not appropriate.
- An EMT is assisting a patient who takes prescribed albuterol via a metered-dose inhaler for an asthma attack. What is the primary therapeutic goal of this medication?
- To increase blood pressure during the attack
- To reduce airway mucus production directly
- To relax bronchial smooth muscle and relieve bronchospasm
- To sedate the patient to slow the respiratory rate
Correct answer: To relax bronchial smooth muscle and relieve bronchospasm
Correct answer: To relax bronchial smooth muscle and relieve bronchospasm. Explanation: Albuterol is a beta-2 agonist bronchodilator whose purpose is to relax constricted bronchial smooth muscle, opening the airways during an asthma or COPD exacerbation. It is not given to dry secretions, raise blood pressure, or sedate the patient, and slowing the respiratory rate is not a treatment goal in bronchospasm.
- An EMT responds to an adult who is unresponsive with slow, shallow breathing and pinpoint pupils after a suspected opioid overdose. After supporting ventilation, what treatment is indicated?
- Assist with the patient's prescribed nitroglycerin
- Administer oral glucose between the cheek and gum
- Administer activated charcoal
- Administer naloxone per protocol
Correct answer: Administer naloxone per protocol
Correct answer: Administer naloxone per protocol. Explanation: Naloxone is the opioid antagonist that reverses the respiratory depression of an opioid overdose, and it is given after the EMT supports ventilation. Oral glucose treats hypoglycemia, activated charcoal is not used in an unresponsive patient with airway risk, and nitroglycerin treats cardiac chest pain rather than opioid toxicity.
- An EMT is treating a conscious adult patient with chest pain consistent with a possible cardiac event and no contraindications. Which medication is most appropriate to administer or assist with first?
- Aspirin, chewed
- Oral glucose
- Naloxone
- Activated charcoal
Correct answer: Aspirin, chewed
Correct answer: Aspirin, chewed. Explanation: For a conscious cardiac chest pain patient without contraindications such as allergy or active bleeding, chewable aspirin is given to inhibit platelet aggregation and limit clot growth in the coronary arteries. Oral glucose treats hypoglycemia, naloxone reverses opioids, and activated charcoal is for certain ingested poisons, none of which addresses suspected acute coronary syndrome.
- An EMT is caring for a known diabetic who is conscious, able to swallow, and exhibits confusion and diaphoresis suggesting hypoglycemia. What is the most appropriate treatment?
- Withhold all treatment and transport silently
- Administer oral glucose
- Administer aspirin
- Give the patient nothing because the cause is uncertain
Correct answer: Administer oral glucose
Correct answer: Administer oral glucose. Explanation: A conscious diabetic who can swallow and shows signs of hypoglycemia should receive oral glucose to raise blood sugar quickly. Withholding treatment risks deterioration, aspirin does nothing for low blood sugar, and refusing care because of uncertainty ignores the classic presentation that oral glucose safely addresses.
- An EMT is treating a patient with a suspected closed femur fracture and no signs of life-threatening injury. Which device is most appropriate to manage this isolated injury?
- An occlusive dressing
- A rigid cervical collar
- A traction splint
- A pelvic binder
Correct answer: A traction splint
Correct answer: A traction splint. Explanation: An isolated, closed midshaft femur fracture is managed with a traction splint, which aligns the bone, reduces pain, and limits further soft-tissue and vascular injury from muscle spasm. A cervical collar is for spinal protection, an occlusive dressing seals open wounds, and a pelvic binder stabilizes the pelvis, not the femur shaft.
- An EMT is splinting a deformed forearm. What should be assessed before and after applying the splint?
- Lung sounds in all fields
- The patient's blood glucose level
- Pupil size and reactivity
- Distal pulse, motor function, and sensation
Correct answer: Distal pulse, motor function, and sensation
Correct answer: Distal pulse, motor function, and sensation. Explanation: Before and after splinting any extremity, the EMT must check distal pulse, motor function, and sensation to confirm that circulation and nerve function are intact and that the splint did not compromise them. Blood glucose, pupil assessment, and lung sounds are unrelated to monitoring the neurovascular status of a splinted limb.
- An EMT is treating a patient with an open chest wound that bubbles with each breath. What is the most appropriate initial treatment?
- Apply an occlusive dressing over the wound
- Pack the wound with sterile gauze
- Apply a tourniquet above the wound
- Leave the wound open and cover it loosely with dry gauze
Correct answer: Apply an occlusive dressing over the wound
Correct answer: Apply an occlusive dressing over the wound. Explanation: A bubbling open chest (sucking) wound allows air into the pleural space, so an occlusive dressing is applied to prevent air entry while monitoring for tension pneumothorax. Packing it with gauze does not seal the chest, a tourniquet cannot be applied to the torso, and dry loose gauze fails to create the needed airtight barrier.
- An EMT is transporting a patient with a suspected tension pneumothorax after sealing a chest wound. The patient suddenly develops increasing respiratory distress and falling blood pressure. What treatment should the EMT perform?
- Reinforce the occlusive dressing with additional tape on all sides
- Briefly lift one edge of the occlusive dressing to release trapped air
- Place the patient in a head-down position
- Remove all oxygen to reduce pressure in the chest
Correct answer: Briefly lift one edge of the occlusive dressing to release trapped air
Correct answer: Briefly lift one edge of the occlusive dressing to release trapped air. Explanation: When a sealed chest wound leads to a developing tension pneumothorax, momentarily lifting an edge of the occlusive dressing 'burps' the trapped air and relieves the pressure. Fully sealing all sides worsens air trapping, a head-down position does not decompress the chest, and removing oxygen would dangerously worsen hypoxia.
- An EMT is treating a patient with an evisceration of abdominal organs. What is the most appropriate treatment of the exposed organs?
- Apply a dry adherent gauze directly to the organs
- Gently push the organs back into the abdominal cavity
- Cover them with a moist sterile dressing and then an occlusive covering
- Pack the wound tightly to control bleeding
Correct answer: Cover them with a moist sterile dressing and then an occlusive covering
Correct answer: Cover them with a moist sterile dressing and then an occlusive covering. Explanation: Exposed abdominal organs from an evisceration are covered with a moist sterile dressing and an occlusive layer to keep them from drying out and to reduce contamination. The organs are never pushed back inside, dry adherent gauze damages the tissue, and tight packing can injure the exposed viscera.
- An EMT is caring for a patient with a severe nosebleed (epistaxis) and no trauma to the spine. What is the most appropriate treatment?
- Apply a tourniquet to the bridge of the nose
- Have the patient tilt the head back to reduce visible bleeding
- Pack the throat with gauze to absorb the blood
- Have the patient lean forward and pinch the fleshy part of the nostrils
Correct answer: Have the patient lean forward and pinch the fleshy part of the nostrils
Correct answer: Have the patient lean forward and pinch the fleshy part of the nostrils. Explanation: For epistaxis, leaning forward while pinching the soft part of the nostrils controls bleeding and prevents blood from draining into the airway and stomach. Tilting the head back allows blood to be swallowed or aspirated, packing the throat obstructs the airway, and a tourniquet cannot be used on the nose.
- An EMT is treating a patient with full-thickness burns. Which treatment principle should guide care during transport?
- Stop the burning process, cover with a dry sterile dressing, and keep the patient warm
- Apply ice directly to the burned areas
- Break any blisters to relieve pressure
- Apply butter or ointment to soothe the skin
Correct answer: Stop the burning process, cover with a dry sterile dressing, and keep the patient warm
Correct answer: Stop the burning process, cover with a dry sterile dressing, and keep the patient warm. Explanation: Burn care involves halting the burning process, covering the area with a dry sterile dressing, and preventing hypothermia, since burn patients lose heat rapidly. Ice causes further tissue damage and hypothermia, blisters should not be broken because they protect against infection, and ointments or butter trap heat and contaminate the wound.
- An EMT is treating a patient who contacted a dry chemical powder on the skin. What is the most appropriate first step in treatment?
- Immediately flood the area with large amounts of water
- Brush away the dry chemical before irrigating with water
- Apply a neutralizing acid or base to the area
- Cover the chemical with an occlusive dressing
Correct answer: Brush away the dry chemical before irrigating with water
Correct answer: Brush away the dry chemical before irrigating with water. Explanation: A dry chemical should first be brushed off the skin, because adding water before brushing can activate the powder and worsen the burn; irrigation follows after brushing. Neutralizing agents generate heat and additional injury, and an occlusive dressing would trap the corrosive material against the skin.
- An EMT is transporting a patient who has had a generalized seizure and is now in the postictal state. What is the most appropriate treatment during transport?
- Administer oral glucose to prevent another seizure
- Insert an oropharyngeal airway and restrain the patient
- Maintain the airway and place the patient in the recovery position
- Keep the patient supine and tightly secured to limit movement
Correct answer: Maintain the airway and place the patient in the recovery position
Correct answer: Maintain the airway and place the patient in the recovery position. Explanation: A postictal patient is often drowsy with a depressed gag reflex, so airway protection and the recovery (lateral) position help prevent aspiration. An OPA is inappropriate if a gag reflex returns, oral glucose is only for hypoglycemia, and restraining a confused postictal patient supine can worsen agitation and airway risk.
- An EMT is treating a patient with severe heat stroke who has hot skin and an altered mental status. What is the priority treatment?
- Administering oral salt tablets
- Encouraging the patient to drink several glasses of cold water
- Wrapping the patient in blankets to prevent shivering
- Rapid active cooling and prompt transport
Correct answer: Rapid active cooling and prompt transport
Correct answer: Rapid active cooling and prompt transport. Explanation: Heat stroke is a true emergency, and the priority is aggressive active cooling combined with rapid transport to lower core temperature and protect the brain. Oral fluids are unsafe in a patient with altered mental status, blankets trap heat, and salt tablets are not an appropriate field treatment for heat stroke.
- An EMT is treating a patient with severe generalized hypothermia who is unresponsive with a slow, weak pulse. How should this patient be handled and treated?
- Handle gently, prevent further heat loss, and transport without rough movement
- Vigorously rub the extremities to restore circulation
- Immerse the patient rapidly in hot water
- Allow the patient to walk to the ambulance to generate heat
Correct answer: Handle gently, prevent further heat loss, and transport without rough movement
Correct answer: Handle gently, prevent further heat loss, and transport without rough movement. Explanation: A severely hypothermic patient must be handled gently and protected from additional heat loss because rough movement can trigger cardiac dysrhythmias. Vigorous rubbing and rapid hot-water immersion can cause dangerous shifts and arrhythmias, and the patient should never be made to exert or walk.
- An EMT is treating a patient with a suspected ingested poison who is alert and following local protocol allows it. Which treatment may be indicated for certain ingested poisons?
- Inducing vomiting with syrup of ipecac
- Activated charcoal, if directed by medical control or protocol
- Giving milk to neutralize all poisons
- Administering oral glucose to dilute the poison
Correct answer: Activated charcoal, if directed by medical control or protocol
Correct answer: Activated charcoal, if directed by medical control or protocol. Explanation: For certain ingested poisons in an alert patient, activated charcoal may be given when authorized by medical direction because it binds many toxins in the gut. Inducing vomiting with ipecac is no longer recommended due to aspiration risk, milk does not neutralize most poisons, and oral glucose has no role in poisoning.
- An EMT is treating a patient who inhaled a toxic gas in an enclosed space. After ensuring scene safety and removing the patient, what is the priority treatment?
- Have the patient rebreathe into a paper bag
- Administer activated charcoal
- Administer high-concentration oxygen
- Withhold oxygen until lung sounds are assessed
Correct answer: Administer high-concentration oxygen
Correct answer: Administer high-concentration oxygen. Explanation: After removing an inhaled-poison patient from the source, high-concentration oxygen is the priority treatment to displace toxins such as carbon monoxide and correct hypoxia. Activated charcoal is for ingested poisons, rebreathing into a bag worsens hypoxia, and oxygen should never be delayed for a patient with inhalation injury.
- An EMT is treating a patient with a suspected acute ischemic stroke. Beyond supportive care, which transport decision is most important?
- Allowing the patient to walk to the ambulance to assess balance
- Delaying transport until all neurological deficits resolve
- Transport to any facility without prearrival notification
- Rapid transport to a stroke-capable center and notification of the receiving hospital
Correct answer: Rapid transport to a stroke-capable center and notification of the receiving hospital
Correct answer: Rapid transport to a stroke-capable center and notification of the receiving hospital. Explanation: Because stroke treatments are highly time-sensitive, the patient should be transported quickly to a stroke-capable facility with advance notification so the team can prepare. Waiting for deficits to resolve wastes the treatment window, skipping notification delays care, and walking the patient is unsafe and irrelevant to definitive treatment.
- An EMT is treating a patient experiencing a behavioral emergency who is calm but at risk for self-harm. Which approach best guides treatment and transport?
- Use calm reassurance, maintain a safe distance, and transport with continued monitoring
- Leave the patient alone to reduce stimulation
- Immediately apply physical restraints to all psychiatric patients
- Refuse transport because behavioral emergencies are not medical problems
Correct answer: Use calm reassurance, maintain a safe distance, and transport with continued monitoring
Correct answer: Use calm reassurance, maintain a safe distance, and transport with continued monitoring. Explanation: A behavioral emergency patient at risk of self-harm benefits from calm communication, a safe approach, and ongoing observation during transport. Leaving the patient alone increases danger, restraints are reserved for patients who are an imminent threat and cannot be managed otherwise, and behavioral emergencies require medical evaluation and transport.
- An EMT is caring for a patient with a suspected spinal injury who must be moved. Which method of moving and transport is most appropriate?
- Have the patient stand and walk to the stretcher to avoid jostling
- Use coordinated manual stabilization to keep the spine in neutral alignment during the move
- Move the patient quickly by the arms and legs
- Place the patient prone to protect the airway
Correct answer: Use coordinated manual stabilization to keep the spine in neutral alignment during the move
Correct answer: Use coordinated manual stabilization to keep the spine in neutral alignment during the move. Explanation: A patient with a suspected spinal injury must be moved with coordinated manual in-line stabilization to keep the spine in neutral alignment and prevent secondary injury. Walking the patient, lifting by the limbs, or placing the patient prone can all twist or flex the spine and worsen any cord injury.
- An EMT is treating a patient with a suspected unstable pelvic fracture and signs of shock. Which treatment helps stabilize the injury during transport?
- Log roll the patient repeatedly to assess for deformity
- Apply a traction splint to both legs
- Apply a pelvic binder to reduce pelvic volume and limit hemorrhage
- Have the patient flex the hips to relieve pressure
Correct answer: Apply a pelvic binder to reduce pelvic volume and limit hemorrhage
Correct answer: Apply a pelvic binder to reduce pelvic volume and limit hemorrhage. Explanation: An unstable pelvic fracture with shock is managed with a pelvic binder, which compresses and stabilizes the pelvis to reduce internal bleeding. Traction splints are for femur fractures, repeated log rolling can aggravate bleeding, and flexing the hips destabilizes the fractured pelvis.
- An EMT is treating a patient with an impaled object in the forearm. What is the most appropriate treatment?
- Apply a tourniquet directly over the object
- Remove the object to allow proper bandaging
- Push the object deeper to prevent it from falling out
- Stabilize the object in place with bulky dressings and transport
Correct answer: Stabilize the object in place with bulky dressings and transport
Correct answer: Stabilize the object in place with bulky dressings and transport. Explanation: An impaled object is stabilized in place with bulky dressings and left for hospital removal, because pulling it out can cause severe bleeding and additional tissue damage. Removing or pushing the object worsens injury, and a tourniquet placed over the object would not control bleeding properly.
- An EMT is treating a patient with an amputated finger. How should the amputated part be managed for transport?
- Wrap it in moist sterile gauze, seal it in a bag, and keep it cool
- Place the part directly on ice to freeze it
- Submerge the part in warm water during transport
- Discard the part since reattachment is impossible in the field
Correct answer: Wrap it in moist sterile gauze, seal it in a bag, and keep it cool
Correct answer: Wrap it in moist sterile gauze, seal it in a bag, and keep it cool. Explanation: An amputated part is wrapped in moist sterile gauze, placed in a sealed bag, and kept cool (not frozen) to preserve the tissue for possible reattachment. Direct contact with ice can cause frostbite damage, warm water hastens tissue breakdown, and the part should always be transported with the patient.
- An EMT is reassessing a patient classified as unstable during transport. How frequently should the EMT repeat the assessment and vital signs?
- Approximately every 15 minutes
- Approximately every 5 minutes
- Only once just before arrival at the hospital
- Only if the patient reports new symptoms
Correct answer: Approximately every 5 minutes
Correct answer: Approximately every 5 minutes. Explanation: An unstable patient should be reassessed about every 5 minutes so that deterioration and the effects of treatment are caught early; stable patients are reassessed roughly every 15 minutes. Checking only at arrival or only when the patient reports symptoms would miss critical changes in an unstable patient.
- An EMT is treating a patient who is anxious and hyperventilating due to a panic attack, with no signs of a medical cause. What is the most appropriate treatment?
- Administer high-flow oxygen to correct alkalosis
- Have the patient breathe into a paper bag
- Provide calm reassurance and coach the patient to slow their breathing
- Restrain the patient to stop the rapid breathing
Correct answer: Provide calm reassurance and coach the patient to slow their breathing
Correct answer: Provide calm reassurance and coach the patient to slow their breathing. Explanation: For psychogenic hyperventilation with no medical cause, calm reassurance and coaching the patient to slow their breathing are the appropriate treatment. Paper-bag rebreathing is unsafe and no longer recommended because it can cause hypoxia, high-flow oxygen does not address the behavioral cause, and restraint would increase anxiety.
- An EMT is treating a patient with an open soft-tissue wound that is bleeding steadily but not spurting. What is the most appropriate initial treatment?
- Leave the wound uncovered to monitor blood loss
- Apply a tourniquet immediately
- Pour antiseptic into the wound to stop the bleeding
- Apply direct pressure with a sterile dressing
Correct answer: Apply direct pressure with a sterile dressing
Correct answer: Apply direct pressure with a sterile dressing. Explanation: Steady, non-arterial bleeding from an open wound is first controlled with direct pressure using a sterile dressing, which is effective for the majority of external bleeding. A tourniquet is reserved for life-threatening extremity hemorrhage that pressure cannot control, antiseptic does not stop bleeding, and leaving the wound uncovered allows continued blood loss and contamination.
- Your ambulance is involved in a collision while responding to a call with lights and siren activated. Which phase of an emergency vehicle response is statistically associated with the highest risk of a serious crash?
- Idling at the scene with the engine running
- Backing into the station after the call
- Driving on a clear, straight rural highway
- Passing through controlled intersections
Correct answer: Passing through controlled intersections
Passing through controlled intersections is correct because the majority of serious ambulance collisions occur at intersections, where other drivers may not yield or may have a conflicting green light. Even with lights and siren, EMTs must come to a complete stop at red lights and stop signs and proceed only when all lanes are confirmed clear. Backing crashes are common but typically low-speed; idling and open-highway cruising carry far less crash risk than negotiating cross traffic.
- After transporting a patient with a suspected infectious respiratory illness, you must prepare the ambulance for the next call. Which step is the most important for preventing disease transmission to the next patient or crew?
- Restocking the oxygen cylinders before anything else
- Cleaning and disinfecting all surfaces and equipment that contacted the patient
- Refueling the ambulance at the nearest station
- Completing the patient care report in the cab
Correct answer: Cleaning and disinfecting all surfaces and equipment that contacted the patient
Cleaning and disinfecting all surfaces and equipment that contacted the patient is correct because decontamination interrupts the chain of infection and protects the next patient and the crew. EPA-registered disinfectants and proper contact times must be used on the stretcher, rails, and reusable devices. Restocking oxygen, refueling, and documentation are all part of returning to service but do not address infection control, which is the priority after an infectious exposure.
- You arrive at a single-vehicle crash where downed power lines are draped across the car and the driver is conscious inside. What is the most appropriate action?
- Have the driver step out of the vehicle and walk normally toward you
- Approach the vehicle quickly to extricate the patient before a fire starts
- Keep yourself and bystanders away and tell the driver to stay in the vehicle until the power company secures the lines
- Use a dry wooden pole to push the lines off the vehicle before approaching
Correct answer: Keep yourself and bystanders away and tell the driver to stay in the vehicle until the power company secures the lines
Keeping everyone clear and instructing the driver to remain in the vehicle until the utility company de-energizes the lines is correct because the metal frame may be energized, and a patient inside an intact vehicle is generally safer than one stepping into a potentially electrified ground. Attempting to move lines with any object risks electrocution, and rushing to extricate exposes the crew to lethal current. Walking out can complete a circuit through the body if the ground is energized.
- During a long interfacility transport, your patient's condition deteriorates beyond your level of training and certification. What is the most appropriate operational decision?
- Request an intercept with a higher level of care, such as a paramedic or critical care unit
- Continue to the original destination at the same speed and document the change
- Perform interventions outside your scope to stabilize the patient
- Stop and wait at the roadside until the patient improves on their own
Correct answer: Request an intercept with a higher level of care, such as a paramedic or critical care unit
Requesting an intercept with a higher level of care is correct because it brings additional skills and interventions to the patient as quickly as possible without delaying transport. EMTs must operate within their scope, so performing advanced interventions they are not trained or authorized to do is unsafe and illegal. Continuing unchanged ignores the deterioration, and stopping to wait offers no benefit and delays definitive care.
- You complete a call and discover that a controlled substance carried on your unit is missing from the secured drug compartment. What is the most appropriate operational response?
- Wait until the end of the shift to mention it during the regular restock
- Report the discrepancy immediately to your supervisor and follow agency controlled-substance accountability procedures
- Assume it was used on a prior call and take no further action
- Replace it quietly from another unit so the count balances
Correct answer: Report the discrepancy immediately to your supervisor and follow agency controlled-substance accountability procedures
Reporting the discrepancy immediately to a supervisor and following the agency's controlled-substance accountability procedures is correct because missing controlled substances must be tracked, investigated, and documented under regulatory requirements. Replacing it covertly conceals a possible diversion and violates chain-of-custody rules. Delaying the report or assuming prior use both fail the legal duty to account for controlled medications.
- While documenting a patient care report, you realize you charted a blood pressure incorrectly. What is the correct way to fix the error on a written report?
- Use correction fluid to cover the mistake completely and write over it
- Draw a single line through the error, write the correct information, and initial and date the change
- Erase the entry thoroughly so no trace of the original remains
- Leave the error and add a separate report contradicting it later
Correct answer: Draw a single line through the error, write the correct information, and initial and date the change
Drawing a single line through the error, writing the correction, and initialing and dating it is correct because it preserves the original entry while documenting the change, which protects the legal integrity of the record. Correction fluid and erasing both obscure the original and can appear as tampering or falsification. Leaving an error uncorrected, even with a later contradicting note, creates a confusing and legally vulnerable record.
- Your agency uses a checklist at the start of each shift to confirm that the ambulance and its equipment are ready. What is the primary purpose of this daily vehicle and equipment inspection?
- To document mileage for billing the patient's insurance
- To decide which crew member will drive that day
- To satisfy a requirement that has no effect on patient care
- To ensure the vehicle and equipment are operational and fully stocked before responding to calls
Correct answer: To ensure the vehicle and equipment are operational and fully stocked before responding to calls
Ensuring the vehicle and equipment are operational and fully stocked before responding is correct because discovering a dead battery, empty oxygen tank, or missing equipment at the scene can be catastrophic. The pre-shift check catches mechanical and supply problems while there is still time to correct them. Billing mileage, assigning drivers, and rote paperwork are not the safety-critical purpose of the inspection.
- You are dispatched to a residence for an unknown medical problem. While walking up to the house, which scene observation should most increase your concern for personal safety?
- A car parked in the driveway
- A dog barking from inside a fenced yard
- Loud shouting and the sound of objects breaking inside the home
- A porch light that is turned off
Correct answer: Loud shouting and the sound of objects breaking inside the home
Loud shouting and breaking objects are correct because they signal possible violence or an unstable, dangerous environment, warranting staging until law enforcement secures the scene. A dark porch light, a parked car, and a fenced dog are common, low-level findings that rarely indicate a threat. Recognizing escalating signs of violence during the approach is a key operational safety skill for every EMS provider.
- An EMS provider reviews social media posts and openly discusses identifiable details of a recent patient's emergency outside of work. Which legal and operational standard has most directly been violated?
- Standing orders for medication administration
- The principle of due regard while driving
- Patient confidentiality protections such as HIPAA
- The Incident Command System span of control
Correct answer: Patient confidentiality protections such as HIPAA
Patient confidentiality protections such as HIPAA are correct because health information may only be shared for treatment, payment, or operations, and disclosing identifiable patient details publicly is a breach. Due regard concerns emergency driving, span of control is an ICS organizational concept, and standing orders govern medical interventions, none of which address public disclosure of patient information. Protecting patient privacy is a continuous operational and legal duty.
- You witness a coworker repeatedly take shortcuts that endanger patients and falsify portions of patient care reports. As an EMT, what is the most appropriate course of action?
- Report the unsafe and dishonest conduct through your agency's chain of command
- Falsify your own reports to match so the records appear consistent
- Confront the coworker only and agree to keep it private
- Ignore it because it does not involve your own patients
Correct answer: Report the unsafe and dishonest conduct through your agency's chain of command
Reporting the unsafe and dishonest conduct through the chain of command is correct because EMTs have an ethical and often legal duty to protect patients and maintain the integrity of records. Ignoring the behavior allows ongoing patient harm, and a private agreement to stay silent perpetuates the danger. Matching the falsified records makes the EMT complicit in fraud and patient endangerment.
- Your service is updating policies on lights-and-siren use after data showed minimal time savings on many transports. From an operational safety standpoint, when is emergency-mode transport most justified?
- Only when the crew wants to return to service quickly
- When the time saved could meaningfully change the patient's outcome
- Whenever the patient requests a faster ride
- On every transport to keep response statistics high
Correct answer: When the time saved could meaningfully change the patient's outcome
Using emergency mode when the time saved could meaningfully change the patient's outcome is correct because lights and siren increase collision risk and should be reserved for time-critical patients. Routine emergency-mode use for stable patients exposes the crew, patient, and public to needless danger for little benefit. Patient preference and crew convenience are not valid reasons to drive in emergency mode.
- At the end of a call, the receiving emergency department nurse takes over care of your patient. Completing a clear verbal report at this point primarily serves what operational purpose?
- Transferring legal liability entirely away from EMS for past actions
- Demonstrating EMS authority over hospital staff
- Ensuring continuity of care so the hospital can safely continue treatment
- Allowing the crew to skip writing a patient care report
Correct answer: Ensuring continuity of care so the hospital can safely continue treatment
Ensuring continuity of care is correct because the verbal handoff communicates the patient's condition, treatments given, and response so the hospital can continue care without dangerous gaps. The handoff does not erase liability for the care already provided, nor does it replace the written report, which must still be completed. The transfer is a collaboration, not an assertion of authority over hospital staff.
- While restocking after a call, you find a glucometer and a blood pressure cuff that failed their function checks. What is the most appropriate operational action before returning the unit to service?
- Wait to address it until the manufacturer issues a recall
- Remove the faulty equipment from service and replace it with working units
- Tape the devices together so the crew remembers they are unreliable
- Return the unit to service and use the equipment carefully
Correct answer: Remove the faulty equipment from service and replace it with working units
Removing the faulty equipment and replacing it with working units is correct because patient assessment and treatment depend on reliable, functioning equipment, and a malfunctioning device can produce dangerous readings. Returning to service with known-defective equipment risks harming the next patient. Marking devices or waiting for a recall leaves unreliable tools available for use, which is unacceptable.
- Your crew responds to a reported building fire with possible victims trapped inside. As EMS providers, what is your most appropriate role on this scene?
- Take command of fire suppression operations
- Enter the burning structure to search for victims yourselves
- Block the building entrance with the ambulance to control access
- Stage in a safe area and provide care to victims after fire personnel rescue and bring them out
Correct answer: Stage in a safe area and provide care to victims after fire personnel rescue and bring them out
Staging in a safe area and treating victims after rescue is correct because EMS providers are not trained or equipped for interior firefighting or rescue, and entering a burning structure endangers the crew. Fire suppression and search are the fire department's responsibilities under unified command. Blocking the entrance with the ambulance would obstruct fire apparatus and rescue efforts.
- You are caring for a critically ill patient and must decide which hospital to transport to. Which factor should most strongly guide your choice of destination?
- The hospital closest to the station to speed the return trip
- The hospital the crew personally prefers to visit
- The closest appropriate facility capable of treating the patient's specific condition
- Whichever facility has the shortest emergency department wait that day
Correct answer: The closest appropriate facility capable of treating the patient's specific condition
Choosing the closest appropriate facility capable of treating the patient's specific condition is correct because some emergencies, such as stroke or major trauma, require specialized centers, and destination selection must match patient need within protocol. Crew preference and proximity to the station are irrelevant to patient outcome. Wait times may inform routine decisions but never override the need for a facility that can treat the actual condition.
- During an emergency response, your partner is driving with lights and siren but motorists ahead are not yielding and appear unaware of the ambulance. What is the safest operational practice?
- Slow down, increase following distance, and assume other drivers may not see or hear you
- Maintain high speed and rely on the siren to clear all traffic
- Tailgate the vehicle ahead to pressure the driver to move
- Pass on the right shoulder at full speed without slowing
Correct answer: Slow down, increase following distance, and assume other drivers may not see or hear you
Slowing down, increasing following distance, and assuming other drivers may not perceive the ambulance is correct because warning devices request the right of way but do not guarantee it, and many drivers are distracted or unable to hear the siren. Relying on speed, tailgating, or high-speed shoulder passing dramatically increases collision risk. Defensive driving with due regard protects the crew, patient, and public.
- Your agency requires every patient encounter to be documented even when no transport occurs. Why is thorough documentation of a non-transport or refusal encounter operationally important?
- It is only needed so the agency can bill for the response
- It replaces the need to obtain a signed refusal
- It allows the crew to change the record later if the patient is harmed
- It provides a legal record of the assessment, advice given, and the patient's decision
Correct answer: It provides a legal record of the assessment, advice given, and the patient's decision
Providing a legal record of the assessment, advice given, and the patient's decision is correct because documentation is the primary protection for both patient and provider if questions or litigation arise later. It supplements, not replaces, a signed refusal where required. Documentation exists for accuracy and accountability, not to enable later alteration of the record, which would be falsification.
- You are positioning the ambulance at the scene of a highway crash in a travel lane. Which practice best protects you and your crew from being struck by passing traffic?
- Position the ambulance to shield the work area and use warning lights and traffic cones or flares
- Turn off all emergency lights to avoid distracting passing drivers
- Park well past the scene so the patient is between you and oncoming traffic
- Have crew members stand in the open travel lane to wave cars through
Correct answer: Position the ambulance to shield the work area and use warning lights and traffic cones or flares
Positioning the ambulance to shield the work area and using warning lights and cones or flares is correct because the apparatus acts as a barrier and the warning devices alert approaching drivers, creating a protected zone. Placing the patient between the crew and traffic exposes both to being struck. Turning off lights removes a critical warning, and standing in live lanes is extremely dangerous.
- A patient is being transferred from one facility to another, and you must keep their personal medical records secure during transport. Which practice best protects this information?
- Keep records covered or secured and release them only to authorized receiving personnel
- Photograph the records on a personal phone for convenience
- Leave the paperwork on the bench seat visible to anyone who enters
- Discuss the contents loudly with the patient in a crowded hallway
Correct answer: Keep records covered or secured and release them only to authorized receiving personnel
Keeping records covered or secured and releasing them only to authorized receiving personnel is correct because protected health information must be safeguarded against unauthorized access at all times, including during transport. Leaving records visible, copying them onto personal devices, and discussing details where others can overhear are all confidentiality breaches. Continuous protection of patient information is an operational and legal requirement.
- You and your partner are returning to quarters when you witness a serious collision directly in front of you. From an operational standpoint, what should you do first?
- Continue to quarters and let another unit be dispatched separately
- Move the wrecked vehicles off the road before assessing patients
- Begin patient care without telling anyone you have stopped
- Notify dispatch of the collision and your status before taking action
Correct answer: Notify dispatch of the collision and your status before taking action
Notifying dispatch of the collision and your status first is correct because the communications center must know you are now committed to this incident so it can send additional resources and track unit availability. Beginning care without notification leaves the system blind to your status and the new incident. Driving past abandons potential patients, and moving vehicles is unsafe and not the EMT's role before assessment.
- Your service is reviewing how crew members lift and move patients after several back injuries. Which operational practice most effectively reduces lifting injuries over time?
- Using powered or mechanical lifting devices and adequate personnel for heavy lifts
- Carrying patients down stairs without any assistive device to save time
- Encouraging crews to lift faster to spend less time bearing the load
- Assigning the strongest single crew member to lift alone
Correct answer: Using powered or mechanical lifting devices and adequate personnel for heavy lifts
Using powered or mechanical lifting devices and adequate personnel is correct because reducing the load on the provider's body is the most reliable way to prevent cumulative lifting injuries. Lifting faster increases the risk of losing control of the load, and assigning one strong person to lift alone overloads that individual. Carrying patients down stairs without assistive equipment is hazardous to both crew and patient.
- While performing a secondary assessment on a responsive medical patient complaining of abdominal pain, which approach best gathers a focused history of the present complaint?
- Use the OPQRST mnemonic to explore onset, provocation, quality, radiation, severity, and timing of the pain
- Begin a rapid head-to-toe trauma exam before asking any questions
- Immediately measure only the blood glucose level and skip further questioning
- Limit questions to the patient's name and date of birth to save time
Correct answer: Use the OPQRST mnemonic to explore onset, provocation, quality, radiation, severity, and timing of the pain
The correct approach is using the OPQRST mnemonic to explore onset, provocation, quality, radiation, severity, and timing. For a responsive medical patient, the secondary assessment centers on a focused history; OPQRST systematically characterizes the chief complaint, while a rapid full-body trauma exam is reserved for significant trauma, and limiting questions to identifiers omits clinically essential information.
- During the secondary assessment, an EMT obtains a patient's medications, allergies, and past medical history. Which mnemonic organizes this complete patient history?
- SAMPLE, which covers signs/symptoms, allergies, medications, pertinent history, last oral intake, and events leading up
- DCAP-BTLS, used only for inspecting injury sites
- AVPU, used only to grade level of responsiveness
- START, used only for multiple-casualty triage
Correct answer: SAMPLE, which covers signs/symptoms, allergies, medications, pertinent history, last oral intake, and events leading up
The correct answer is SAMPLE, which captures signs/symptoms, allergies, medications, pertinent past history, last oral intake, and events leading to the call. DCAP-BTLS describes physical exam findings at injury sites, AVPU grades responsiveness, and START is a triage tool, so none gather a full medical history.
- An unresponsive adult who is breathing adequately has no suspected spinal injury after a syncopal episode. What is the most appropriate position to help maintain a patent airway during transport?
- The recovery (lateral recumbent) position so secretions can drain and the tongue does not obstruct the airway
- Supine and flat with the head turned forcefully to one side
- Seated fully upright and restrained tightly at the chest
- Prone with the face pressed directly against the stretcher
Correct answer: The recovery (lateral recumbent) position so secretions can drain and the tongue does not obstruct the airway
The recovery (lateral recumbent) position is correct because it allows secretions and vomitus to drain from the mouth and keeps the tongue from blocking the airway in an unresponsive patient without suspected spinal injury. Forcing the head while supine, seating upright, or placing the patient prone with the face down all risk airway compromise.
- A diabetic patient is awake, able to swallow, and protecting their own airway, with a low blood glucose reading and symptoms of hypoglycemia. Within the EMT scope, what is the appropriate treatment?
- Administer oral glucose because the patient is conscious and can safely swallow
- Administer oral glucose only after the patient becomes unresponsive
- Withhold all treatment until blood pressure exceeds 140 systolic
- Give the patient a full meal of solid food immediately
Correct answer: Administer oral glucose because the patient is conscious and can safely swallow
Administering oral glucose is correct because an EMT may give it to a conscious patient with suspected hypoglycemia who can swallow and protect the airway. Waiting until the patient is unresponsive would make oral glucose unsafe due to aspiration risk, blood pressure is not the gating criterion, and a full solid meal is not the indicated emergency intervention.
- While forming a general impression as you approach a patient, which AVPU finding indicates the lowest level of responsiveness?
- Unresponsive, meaning the patient does not react to verbal or painful stimuli
- Alert, meaning the patient is awake and answering questions appropriately
- Verbal, meaning the patient responds when spoken to
- Painful, meaning the patient responds only to a painful stimulus
Correct answer: Unresponsive, meaning the patient does not react to verbal or painful stimuli
Unresponsive is correct because on the AVPU scale it represents the lowest level of responsiveness, with the patient reacting to neither verbal nor painful stimuli. Alert is the highest level, Verbal indicates a response to speech, and Painful indicates a response only to painful stimulation, all of which rank above Unresponsive.
