- An AEMT is monitoring a non-arrested adult with waveform capnography after assisting ventilations for a drug overdose. The displayed number reads 40 mm Hg with a normal rectangular waveform. Which statement best describes this end-tidal carbon dioxide (EtCO2) reading?
- It cannot be interpreted because EtCO2 measures oxygen, not carbon dioxide
- It falls within the normal range of about 35 to 45 mm Hg
- It is dangerously high and indicates the patient is barely breathing
- It is below normal and indicates the patient is being over-ventilated
Correct answer: It falls within the normal range of about 35 to 45 mm Hg
A reading of 40 mm Hg falls within the normal EtCO2 range of about 35 to 45 mm Hg, indicating adequate ventilation at this moment. End-tidal CO2 (EtCO2) is the partial pressure of carbon dioxide measured at the end of an exhaled breath, and capnography reflects how effectively CO2 is being eliminated, not how well the patient is oxygenated. Values below 35 suggest hyperventilation or low perfusion, while values above 45 suggest hypoventilation or CO2 retention.
- During patient assessment, an AEMT notes a 60-year-old man breathing 6 times per minute with shallow, barely perceptible chest movement, cyanotic lips, and a falling pulse oximetry reading. Which finding most clearly tells the AEMT that ventilations are inadequate and assisted ventilation is required?
- Pink, warm, dry skin with a regular pulse
- A respiratory rate of 6 per minute with shallow chest rise and cyanosis
- A pulse oximetry reading of 98 percent on room air
- Clear and equal breath sounds in all lung fields
Correct answer: A respiratory rate of 6 per minute with shallow chest rise and cyanosis
A respiratory rate of 6 per minute with shallow chest rise and cyanosis signals inadequate ventilation and the need for assisted ventilation with a bag-valve mask. Adequate ventilation produces an adequate rate and depth (tidal volume), visible and equal chest rise, and good color; signs of inadequate ventilation include a too-slow or too-fast rate, shallow or absent chest movement, cyanosis, and falling oxygen saturation. Clear equal breath sounds, a normal SpO2, and pink warm skin are reassuring findings, not indicators of failure.
- An AEMT finds an apneic adult with a pulse but no gag reflex following a heroin overdose; assisted ventilations with chest rise are needed before transport. Which device is the most appropriate choice for delivering positive-pressure ventilation in this situation?
- A bag-valve mask connected to high-flow oxygen
- A simple face mask at 6 liters per minute
- A nasal cannula running at 4 liters per minute
- A non-rebreather mask at 15 liters per minute
Correct answer: A bag-valve mask connected to high-flow oxygen
A bag-valve mask connected to high-flow oxygen is the appropriate device when a patient is not breathing adequately on their own, because it delivers positive-pressure ventilation that moves air into the lungs. The bag-valve mask is indicated whenever a patient is apneic or has an inadequate rate or depth of breathing, such as this apneic overdose patient. Nasal cannulas, non-rebreather masks, and simple masks only supply supplemental oxygen to a patient who is already breathing adequately and cannot ventilate someone who is not.
- An AEMT prepares to insert a King LT or i-gel into an unresponsive, apneic, pulseless adult during cardiac arrest. What feature characterizes these supraglottic airways within the AEMT scope of practice?
- They are blind insertion airway devices advanced into the pharynx without seeing the cords
- They deliver medications directly into the bloodstream
- They require direct visualization of the vocal cords with a laryngoscope
- They are inserted surgically through the cricothyroid membrane
Correct answer: They are blind insertion airway devices advanced into the pharynx without seeing the cords
The King LT and i-gel are blind insertion airway devices (also called supraglottic airway devices) that are advanced into the pharynx without directly visualizing the vocal cords. They seat in the hypopharynx so the ventilation opening sits over the glottic opening, making them well suited to AEMT scope because no laryngoscopy or vocal-cord visualization is needed. Endotracheal intubation requires visualizing the cords and surgical cricothyrotomy cuts through the neck, both beyond typical AEMT practice.
- After inserting an i-gel supraglottic airway and beginning ventilations, an AEMT attaches waveform capnography. A consistent rectangular waveform with an EtCO2 of 38 mm Hg appears with each ventilation. How does this confirm correct airway placement?
- It shows the patient has regained a pulse
- It measures the depth of insertion in centimeters
- It proves oxygen saturation has reached 100 percent
- Detection of exhaled carbon dioxide confirms the device is ventilating the lungs, not the esophagus
Correct answer: Detection of exhaled carbon dioxide confirms the device is ventilating the lungs, not the esophagus
Detection of exhaled carbon dioxide on the waveform confirms the airway is ventilating the lungs rather than the esophagus, because CO2 is produced by the lungs and not the stomach. Capnography confirms placement by sustaining a normal waveform and an EtCO2 reading (here 38 mm Hg, within the normal 35 to 45 mm Hg range) breath after breath; a flat or absent waveform would warn of misplacement. Capnography does not measure oxygen saturation, insertion depth, or pulse return.
- An AEMT assesses a 28-year-old woman with a known asthma history who has audible wheezing, accessory muscle use, and a SpO2 of 90 percent. Following protocol and the AEMT formulary, what is the most appropriate medication and dose to administer?
- Aspirin 324 mg chewed
- Epinephrine 0.3 mg of the 1:10,000 concentration given intravenously
- Nitroglycerin 0.4 mg under the tongue
- Albuterol 2.5 mg nebulized with oxygen
Correct answer: Albuterol 2.5 mg nebulized with oxygen
Albuterol 2.5 mg nebulized with oxygen is the appropriate treatment for an asthma patient with wheezing and respiratory distress, because albuterol is a beta-2 agonist that relaxes bronchial smooth muscle and opens the airways. The standard adult AEMT nebulized dose is 2.5 mg (commonly supplied as 2.5 mg in 3 mL) run with oxygen. Pushing IV epinephrine, aspirin, and nitroglycerin do not treat bronchospasm; IV cardiac epinephrine in particular is outside AEMT scope, and for anaphylaxis the AEMT route would be intramuscular epinephrine 1:1,000, not IV.
- A 58-year-old man is unresponsive, not breathing normally, and has no carotid pulse. Your partner begins chest compressions. At what rate should the AEMT deliver chest compressions for this adult?
- As fast as physically possible
- 100 to 120 compressions per minute
- 60 to 80 compressions per minute
- 140 to 160 compressions per minute
Correct answer: 100 to 120 compressions per minute
A rate of 100 to 120 compressions per minute is the current American Heart Association ECC standard for adult CPR. Going slower than 100 reduces coronary and cerebral perfusion, while pushing faster than 120 shortens the recoil phase and reduces the blood that refills the heart between compressions, so both extremes lower the chance of survival.
- During single-rescuer CPR on an adult who has no advanced airway in place, what compression-to-ventilation ratio should the AEMT use?
- 5 compressions to 1 breath
- Continuous compressions with no breaths
- 15 compressions to 2 breaths
- 30 compressions to 2 breaths
Correct answer: 30 compressions to 2 breaths
A ratio of 30 compressions to 2 breaths is the standard for adult CPR without an advanced airway, whether one or two rescuers are present. The 15-to-2 ratio applies only to two-rescuer CPR on infants and children, not adults. Once an advanced airway is placed, rescuers switch to continuous compressions with breaths delivered separately.
- While performing compressions on an adult in cardiac arrest, the AEMT suddenly feels the patient move and notices the capnography waveform jump from about 12 mmHg to 40 mmHg. What does this sharp rise in end-tidal carbon dioxide most likely indicate?
- Worsening of the patient's metabolic acidosis
- Return of spontaneous circulation
- The compressions have become too shallow
- The endotracheal tube has become dislodged
Correct answer: Return of spontaneous circulation
Return of spontaneous circulation is the most likely explanation for an abrupt rise in end-tidal carbon dioxide during resuscitation. When the heart resumes effective pumping, far more blood and carbon dioxide are delivered to the lungs, so the ETCO2 climbs sharply, often toward normal values near 35 to 45 mmHg. A dislodged tube would cause the waveform to drop or disappear, not rise.
- An AEMT arrives to find a 62-year-old woman who collapsed. She is unresponsive, not breathing, and has no pulse. A bystander AED is available. When is it appropriate to apply and activate the AED?
- Only after at least five minutes of chest compressions
- Only after a paramedic arrives to interpret the rhythm
- Only if the patient has a known history of heart disease
- As soon as the patient is confirmed unresponsive, pulseless, and not breathing normally
Correct answer: As soon as the patient is confirmed unresponsive, pulseless, and not breathing normally
An AED should be applied as soon as a patient is confirmed unresponsive, pulseless, and not breathing normally, because early defibrillation of a shockable rhythm is one of the strongest predictors of survival. The device itself analyzes the rhythm and advises a shock only when appropriate, so the AEMT does not need to interpret the rhythm or wait for a paramedic.
- A 70-year-old man in cardiac arrest has had compressions and an AED applied. The AED analyzes and advises 'no shock advised.' What should the AEMT do immediately?
- Remove the AED pads and reassess the airway
- Repeat the rhythm analysis right away
- Wait two minutes before touching the patient
- Resume high-quality chest compressions
Correct answer: Resume high-quality chest compressions
Resuming high-quality chest compressions immediately is correct after a 'no shock advised' message. A non-shockable result does not mean the patient has a pulse; it means the rhythm is not defibrillatable, so perfusion still depends entirely on compressions. Pausing or removing pads only interrupts blood flow and lowers the chance of survival.
- A 55-year-old man reports crushing substernal chest pressure radiating to his left arm, along with nausea and diaphoresis. Which combination of findings is most characteristic of an acute myocardial infarction?
- Pressure-like chest discomfort with radiation to the arm or jaw, sweating, and nausea
- Sharp pain that worsens with deep breathing and improves when leaning forward
- Localized chest wall pain that reproduces when the area is pressed
- Burning pain that began after eating and improves with antacids
Correct answer: Pressure-like chest discomfort with radiation to the arm or jaw, sweating, and nausea
Pressure-like chest discomfort radiating to the arm or jaw with sweating and nausea is the classic presentation of a myocardial infarction caused by blocked coronary blood flow. Pain that changes with breathing or body position points toward pericarditis or pleuritic causes, and pain reproduced by pressing the chest wall suggests a musculoskeletal source rather than cardiac ischemia.
- A 60-year-old woman has chest pressure, and the AEMT suspects acute coronary syndrome. Her blood pressure is 138/84 and she is not allergic to aspirin and has no signs of active bleeding. Per typical AEMT protocol, what is the appropriate aspirin administration?
- 650 mg chewed
- 1,000 mg swallowed whole
- 81 mg swallowed whole with water
- 162 to 324 mg chewed
Correct answer: 162 to 324 mg chewed
A chewed dose of 162 to 324 mg of aspirin is standard for suspected acute coronary syndrome, commonly given as four 81 mg chewable tablets. Chewing speeds absorption so the drug can block platelet clumping faster, which helps limit clot growth in the blocked coronary artery. Swallowing it whole delays the effect, and doses of 650 mg or more exceed what is indicated.
- A 64-year-old man with chest pain has a blood pressure of 142/88. The AEMT prepares to assist with nitroglycerin. What single sublingual dose is standard, and how often may it be repeated if pain persists and blood pressure stays adequate?
- 40 mg, repeated every 10 minutes
- 4 mg, repeated every 15 minutes up to 2 doses
- 0.4 mg, given only once with no repeat
- 0.4 mg, repeated every 5 minutes up to 3 doses
Correct answer: 0.4 mg, repeated every 5 minutes up to 3 doses
A 0.4 mg sublingual tablet or spray, repeated every 5 minutes for up to 3 doses, is the standard nitroglycerin regimen for cardiac chest pain as long as systolic blood pressure stays above roughly 100 mmHg. Nitroglycerin dilates blood vessels to reduce the heart's workload and improve coronary flow, but giving too much or repeating it with low pressure can cause dangerous hypotension.
- Before assisting a chest-pain patient with nitroglycerin, which question is most important for the AEMT to ask to avoid a dangerous drug interaction?
- Whether the patient has used an erectile-dysfunction drug such as sildenafil or tadalafil recently
- Whether the patient has a history of asthma
- Whether the patient has eaten in the last hour
- Whether the patient has taken any aspirin today
Correct answer: Whether the patient has used an erectile-dysfunction drug such as sildenafil or tadalafil recently
Asking about recent use of erectile-dysfunction drugs such as sildenafil or tadalafil is critical, because combining them with nitroglycerin can cause severe, prolonged hypotension. Both drug types relax blood vessels, and together they can drop blood pressure to life-threatening levels. Recent aspirin, food intake, or asthma do not create this same immediate interaction risk with nitroglycerin.
- A patient with suspected acute coronary syndrome is being treated by an AEMT. Which set of interventions falls within the AEMT scope of practice for this patient?
- Oxygen if hypoxic, aspirin, assisting with nitroglycerin, and rapid transport
- 12-lead ECG interpretation and fibrinolytic administration
- IV push cardiac epinephrine and manual defibrillation
- Synchronized cardioversion and IV push amiodarone
Correct answer: Oxygen if hypoxic, aspirin, assisting with nitroglycerin, and rapid transport
Oxygen when the patient is hypoxic, aspirin, assisting with nitroglycerin, and prompt transport are the appropriate AEMT-level actions for acute coronary syndrome. Synchronized cardioversion, IV push amiodarone, fibrinolytics, and IV push cardiac epinephrine are paramedic-level or hospital interventions outside the AEMT scope of practice.
- An AEMT learns about four major categories of shock: hypovolemic, cardiogenic, distributive, and obstructive. Which description correctly matches a category to its underlying mechanism?
- Obstructive shock results from severe blood or fluid loss
- Cardiogenic shock results from widespread loss of blood vessel tone
- Hypovolemic shock results from the heart failing to pump effectively
- Distributive shock results from blood vessels dilating and losing tone
Correct answer: Distributive shock results from blood vessels dilating and losing tone
Distributive shock results from blood vessels dilating and losing tone, which is seen in anaphylaxis, sepsis, and neurogenic shock. Hypovolemic shock comes from blood or fluid loss, cardiogenic shock from a failing pump, and obstructive shock from a physical blockage to blood flow such as a tension pneumothorax. Matching each type to its mechanism guides the right treatment.
- A 68-year-old man had a heart attack two days ago. He is now pale, cool, and clammy with a blood pressure of 78/50, weak rapid pulse, and crackles in both lungs. Which type of shock do these findings most strongly suggest?
- Hypovolemic shock
- Anaphylactic shock
- Cardiogenic shock
- Neurogenic shock
Correct answer: Cardiogenic shock
Cardiogenic shock is most consistent with low blood pressure, a weak rapid pulse, cool clammy skin, and lung crackles in a patient with recent heart damage. The injured heart cannot pump enough blood forward, so pressure falls while fluid backs up into the lungs. Hypovolemic shock would not typically cause pulmonary crackles, and anaphylactic and neurogenic shock have different triggers and skin findings.
- An AEMT is treating a 25-year-old trauma patient with major external hemorrhage who is showing signs of hypovolemic shock. After controlling the bleeding, which intervention is the appropriate next step within the AEMT scope of practice?
- Administer a vasopressor infusion
- Administer an isotonic crystalloid IV or IO fluid bolus per protocol
- Push IV epinephrine to raise the blood pressure
- Give oral fluids to replace lost volume
Correct answer: Administer an isotonic crystalloid IV or IO fluid bolus per protocol
Administering an isotonic crystalloid IV or IO fluid bolus per protocol is the correct AEMT-level step for hypovolemic shock once bleeding is controlled, because fluid helps restore circulating volume and perfusion. Pushing IV epinephrine and running vasopressor infusions are paramedic-level skills, and oral fluids are inappropriate for a shock patient who may need surgery and cannot reliably absorb them.
- A 30-year-old woman develops hives, swelling of the lips and tongue, wheezing, and a falling blood pressure minutes after a bee sting. Which medication and route is appropriate for the AEMT to administer?
- Nitroglycerin 0.4 mg sublingually
- Epinephrine 1 mg of the 0.1 mg/mL (1:10,000) concentration given IV push
- Epinephrine 0.3 mg of the 1 mg/mL (1:1,000) concentration given intramuscularly
- Aspirin 324 mg chewed
Correct answer: Epinephrine 0.3 mg of the 1 mg/mL (1:1,000) concentration given intramuscularly
Epinephrine 0.3 mg of the 1 mg/mL (1:1,000) concentration given intramuscularly is the correct treatment for anaphylaxis within the AEMT scope. It rapidly tightens blood vessels and opens the airways to reverse the distributive shock and bronchospasm. The 0.1 mg/mL (1:10,000) IV push concentration is reserved for cardiac arrest by paramedics, and nitroglycerin or aspirin would not treat anaphylaxis.
- An AEMT is taught that obstructive shock comes from a physical barrier to normal blood flow through the heart or great vessels. Which condition is a classic cause of obstructive shock?
- A bleeding stomach ulcer
- A severe allergic reaction to peanuts
- A tension pneumothorax compressing the heart and great vessels
- A spinal cord injury causing loss of vascular tone
Correct answer: A tension pneumothorax compressing the heart and great vessels
A tension pneumothorax is a classic cause of obstructive shock because trapped air in the chest compresses the heart and great vessels, physically blocking blood from returning to and leaving the heart. A bleeding ulcer causes hypovolemic shock, a peanut allergy causes distributive (anaphylactic) shock, and a spinal cord injury causes neurogenic shock, none of which involve a mechanical obstruction to flow.
- An AEMT arrives to find a 24-year-old man with a deep, spurting laceration to the upper thigh after a chainsaw injury. Bright red blood is pooling rapidly beneath him and he is pale and anxious. After ensuring scene safety and donning gloves, what should the AEMT do first?
- Open the airway with a jaw-thrust and insert a nasopharyngeal airway
- Apply a commercial tourniquet high and tight on the thigh proximal to the wound and tighten until bleeding stops
- Establish a large-bore IV and begin a rapid fluid bolus
- Apply high-flow oxygen by non-rebreather mask and obtain a full set of vital signs
Correct answer: Apply a commercial tourniquet high and tight on the thigh proximal to the wound and tighten until bleeding stops
Applying a commercial tourniquet proximal to the wound and tightening it until bleeding stops is correct. Current trauma sequencing places control of life-threatening external hemorrhage before airway and breathing, often written as 'XABC,' because a patient can exsanguinate from arterial extremity bleeding faster than an airway problem will kill them. Establishing an IV or applying oxygen are appropriate later steps but do not address the immediate threat of catastrophic blood loss.
- While conducting the primary survey of a trauma patient struck by a car, the AEMT identifies a partially obstructed airway with gurgling sounds during the airway step. According to the structured primary survey approach, what is the most appropriate next action?
- Move on to assess breathing and oxygenation, then return to the airway
- Correct the airway problem with suctioning and positioning before proceeding
- Document the finding and continue to the disability and neurologic check
- Begin the rapid trauma exposure and head-to-toe examination
Correct answer: Correct the airway problem with suctioning and positioning before proceeding
Correcting the airway problem with suctioning and positioning before proceeding is correct. In the ABCDE (Airway, Breathing, Circulation, Disability, Exposure) primary survey, each step must be addressed and any immediate life threat corrected before advancing to the next letter. Moving on to breathing or the exposure exam while the airway is still compromised abandons the sequential 'treat as you find it' principle that prevents a critical injury from being overlooked.
- An AEMT is treating an alert 30-year-old who fell from a standing height. The patient denies neck or back pain, has no midline cervical tenderness on palpation, shows no neurologic deficits, is not intoxicated, and has no distracting injuries. Based on validated low-risk criteria, what is the most appropriate decision regarding spinal care?
- Spinal motion restriction is not indicated, and the patient may be transported without a collar
- Apply a rigid cervical collar and secure the patient to a long backboard for transport
- Apply a cervical collar but omit the backboard
- Defer any movement until a physician clears the spine by radiograph
Correct answer: Spinal motion restriction is not indicated, and the patient may be transported without a collar
Spinal motion restriction is not indicated, and the patient may be transported without a collar, is correct. Validated low-risk criteria such as NEXUS allow EMS to forgo immobilization when the patient has no midline cervical tenderness, no focal neurologic deficit, a normal level of consciousness, no intoxication, and no distracting injury. Routine immobilization of all trauma patients is no longer supported because the collar and board carry harms including pain, pressure injury, and impaired breathing.
- After applying a commercial tourniquet to control arterial bleeding from a mangled forearm, the AEMT confirms the bleeding has stopped. What additional step is essential immediately after the tourniquet is secured?
- Note and record the exact time the tourniquet was applied
- Cover the tourniquet with a blanket so the patient cannot see it
- Apply a second tourniquet distal to the first over the wrist joint
- Loosen the tourniquet every few minutes to allow circulation to the limb
Correct answer: Note and record the exact time the tourniquet was applied
Noting and recording the exact time the tourniquet was applied is correct. Documenting the application time, ideally marked on the patient or the device, lets receiving clinicians track ischemic time and make limb-salvage decisions. A correctly applied tourniquet should not be loosened in the field once bleeding is controlled, and tourniquets are placed proximal to the wound, never over a joint such as the wrist.
- An AEMT assesses a 40-year-old with blunt abdominal trauma who is anxious, has cool and clammy skin, a heart rate of 124, and a narrowing pulse pressure, although the systolic blood pressure is still in the normal range. These findings are most consistent with which stage of hemorrhagic shock?
- Irreversible shock
- Neurogenic shock
- Decompensated shock with profound hypotension
- Compensated (early) shock
Correct answer: Compensated (early) shock
Compensated (early) shock is correct. In compensated shock the body sustains blood pressure through tachycardia and vasoconstriction, producing cool clammy skin, anxiety, an elevated heart rate, and a narrowing pulse pressure while the systolic pressure remains near normal. A falling systolic pressure marks the transition to decompensated shock, so recognizing these early compensatory signs lets the AEMT intervene before blood pressure collapses.
- An AEMT is monitoring a patient with a severe head injury after a fall. Over several minutes the patient's blood pressure rises markedly, the heart rate slows, and the breathing pattern becomes irregular. The patient is now responsive only to pain. What does this combination of findings most likely indicate?
- Spinal (neurogenic) shock from a cervical cord injury
- Rising intracranial pressure with impending brain herniation
- A vasovagal response to the painful stimulus
- Developing hypovolemic shock from an occult abdominal bleed
Correct answer: Rising intracranial pressure with impending brain herniation
Rising intracranial pressure with impending brain herniation is correct. The triad of rising blood pressure, slowing heart rate, and irregular respirations, known as Cushing's triad, signals dangerously high intracranial pressure and a brain at risk of herniation. This is the opposite of hypovolemic shock, which produces a low blood pressure and a fast heart rate, and unlike neurogenic shock, which causes hypotension with a slow heart rate.
- A 54-year-old diabetic is confused, diaphoretic, shaky, and tachycardic with cool, pale skin. His finger-stick blood glucose reads 44 mg/dL. Which cluster of findings is most consistent with hypoglycemia in this patient?
- Slow heart rate with flushed warm skin and constricted pupils
- Cool, sweaty skin with confusion, tremor, and rapid heart rate
- Gradual onset of thirst, frequent urination, and abdominal pain over days
- Hot, dry skin with deep rapid breathing and a fruity breath odor
Correct answer: Cool, sweaty skin with confusion, tremor, and rapid heart rate
Cool, sweaty skin with confusion, tremor, and a rapid heart rate is the classic hypoglycemia picture. As glucose falls, the body releases adrenaline, producing diaphoresis, shakiness, and tachycardia, while the brain's lack of fuel causes confusion and altered mental status. Hot, dry skin with deep rapid (Kussmaul) breathing and a fruity odor describes diabetic ketoacidosis from high glucose, the opposite problem.
- An AEMT performs the Cincinnati Prehospital Stroke Scale on a patient with sudden weakness. Which three findings does this scale assess?
- Headache severity, neck stiffness, and visual fields
- Pupil size, grip strength, and level of consciousness
- Blood pressure, blood glucose, and gait
- Facial droop, arm drift, and speech/slurred words
Correct answer: Facial droop, arm drift, and speech/slurred words
The Cincinnati Prehospital Stroke Scale assesses facial droop, arm drift, and speech (abnormal or slurred words). Any single abnormal finding markedly raises the probability of stroke and should prompt rapid transport to a stroke-capable center. The other groupings mix in measurements such as pupils or blood pressure that are not part of this three-item screen.
- A bystander asks an AEMT how to remember the warning signs of stroke. Which mnemonic and meaning should the AEMT teach?
- SAMPLE: Signs, Allergies, Medications, Past history, Last intake, Events
- RICE: Rest, Ice, Compression, Elevation
- FAST: Face drooping, Arm weakness, Speech difficulty, Time to call 911
- AVPU: Alert, Verbal, Pain, Unresponsive
Correct answer: FAST: Face drooping, Arm weakness, Speech difficulty, Time to call 911
FAST stands for Face drooping, Arm weakness, Speech difficulty, and Time to call 911. It distills the same components as the Cincinnati Prehospital Stroke Scale into a public-friendly tool that emphasizes acting quickly because stroke treatment is time-sensitive. RICE is for musculoskeletal injury, SAMPLE is a history tool, and AVPU grades responsiveness.
- An adult is found unresponsive to voice but groans and localizes when a trapezius pinch is applied; eyes open to pain and speech is incomprehensible. Using the Glasgow Coma Scale, what is this patient's total score?
Correct answer: 9
The score is 9. Eyes opening to pain scores 2, incomprehensible sounds score 2, and localizing to pain scores 5 on the motor scale, totaling 9. The Glasgow Coma Scale adds Eye (1-4), Verbal (1-5), and Motor (1-6) components. Localizing (purposeful movement toward the stimulus) is M5, distinct from withdrawal (M4) and obeying commands (M6).
- An AEMT documents a patient as alert and fully oriented, following commands, and speaking normally. What is this patient's Glasgow Coma Scale score, and what does that represent?
- A score of 15, the highest and normal score
- A score of 8, the threshold for airway concern
- A score of 3, the lowest possible score
- A score of 10, a moderately impaired score
Correct answer: A score of 15, the highest and normal score
A normal Glasgow Coma Scale score is 15, the highest possible total. It reflects spontaneous eye opening (4), oriented verbal response (5), and obeying commands (6). The lowest possible score is 3, which represents no eye, verbal, or motor response.
- A 30-year-old who was stung by a bee has hives, lip swelling, wheezing, and a blood pressure of 78/40 mmHg. Which set of findings best characterizes anaphylaxis?
- Skin changes such as hives plus airway swelling/wheeze and hypotension
- Isolated localized swelling at the sting site with normal vital signs
- Chest pain radiating to the arm with diaphoresis and nausea
- Fever, neck stiffness, and a non-blanching rash
Correct answer: Skin changes such as hives plus airway swelling/wheeze and hypotension
Anaphylaxis is a multi-system allergic reaction: skin findings like hives or flushing combined with respiratory compromise (airway swelling, wheeze) and cardiovascular collapse (hypotension). Involvement of more than one body system distinguishes anaphylaxis from a localized reaction. Isolated swelling at the sting site without systemic signs is not anaphylaxis.
- A patient in anaphylaxis has stridor, diffuse hives, and a falling blood pressure. Within the AEMT scope, what is the most appropriate first medication and route?
- Diphenhydramine intravenously as the sole treatment
- Albuterol by nebulizer as the definitive treatment
- Epinephrine 1:1,000 (1 mg/mL), 0.3 mg intramuscularly
- Epinephrine 1:10,000 (0.1 mg/mL), 1 mg intravenous push
Correct answer: Epinephrine 1:1,000 (1 mg/mL), 0.3 mg intramuscularly
Epinephrine 1:1,000 (1 mg/mL) given 0.3 mg intramuscularly is the first-line treatment for anaphylaxis and is within the AEMT scope. IM epinephrine reverses airway swelling, bronchospasm, and vasodilation. The 1:10,000 concentration given IV push is a cardiac-arrest dose and is not an AEMT skill. Antihistamines and albuterol are adjuncts, not the primary intervention.
- An AEMT is treating an adult in anaphylaxis. Which statement about the epinephrine dose and concentration is correct?
- Give the 1:1,000 concentration, 0.3 mg, intramuscularly into the lateral thigh
- Give the 1:1,000 concentration, 1 mg, by slow IV push
- Give the 1:10,000 concentration, 1 mg, intramuscularly
- Give the 1:10,000 concentration, 0.3 mg, intramuscularly into the deltoid
Correct answer: Give the 1:1,000 concentration, 0.3 mg, intramuscularly into the lateral thigh
The correct adult anaphylaxis dose is epinephrine 1:1,000 (1 mg/mL), 0.3 mg, intramuscularly, preferably in the lateral thigh for fast absorption. The 1:10,000 dilution is reserved for cardiac arrest and IV use by paramedics, not for anaphylaxis. Giving 1 mg of the concentrated solution IM or pushing 1:1,000 IV would be dangerous overdoses.
- A known diabetic is unconscious with no IV access yet established and a glucose of 38 mg/dL. Within the AEMT scope, which medication can be given without a line, and by what route?
- 50% dextrose 25 g intramuscularly
- Glucagon 1 mg intramuscularly
- Oral glucose gel placed in the cheek of the unconscious patient
- Insulin subcutaneously to balance glucose
Correct answer: Glucagon 1 mg intramuscularly
Glucagon 1 mg given intramuscularly is appropriate when IV access is not yet available because it does not require a vein. It raises blood glucose by triggering the liver to release stored glucose. Dextrose must be given IV, never IM. Oral glucose is contraindicated in an unconscious patient due to aspiration risk, and insulin would lower glucose further.
- An AEMT establishes an IV on a hypoglycemic, unresponsive adult with a glucose of 35 mg/dL. Which dextrose order reflects current AEMT practice for this patient?
- 10% dextrose, 250 g IV rapid push
- 50% dextrose, 25 g intramuscularly
- 5% dextrose, 25 g IV push undiluted
- 50% dextrose, 25 g IV (one 50 mL prefilled syringe)
Correct answer: 50% dextrose, 25 g IV (one 50 mL prefilled syringe)
50% dextrose, 25 g IV — the standard 50 mL prefilled (D50) syringe — is the classic dose for adult hypoglycemia with IV access. Many systems now favor 10% dextrose (D10) in 25 g titrated boluses to reduce vein irritation, but the single 25 g amount is the same target. Dextrose is never given IM, and 250 g would be a tenfold overdose.
- A diabetic with an altered mental status has a glucose of 42 mg/dL but is still able to follow commands and swallow safely. What is the most appropriate AEMT treatment?
- Withhold treatment until the patient becomes unresponsive
- Administer oral glucose gel or paste
- Push 50% dextrose IV immediately
- Give glucagon intramuscularly
Correct answer: Administer oral glucose gel or paste
Oral glucose gel or paste is appropriate because the patient is awake and able to protect the airway and swallow. Oral glucose is the least invasive route and is effective for a conscious hypoglycemic patient. IV dextrose and IM glucagon are reserved for patients who cannot safely swallow or are unresponsive; withholding treatment is never appropriate for symptomatic hypoglycemia.
- An AEMT must decide between IV dextrose and IM glucagon for a hypoglycemic patient. Which factor most appropriately favors choosing dextrose?
- The patient has eaten recently
- A patent IV line is already established
- No IV access can be obtained
- The patient has chronic alcoholism with depleted glycogen stores
Correct answer: A patent IV line is already established
A patent IV line already in place favors IV dextrose because it works almost immediately and is more reliable than glucagon. Glucagon is chosen when no IV access is available, since it can be given IM. Glucagon also works poorly in patients with depleted liver glycogen stores, such as those with chronic alcoholism or malnutrition, making dextrose preferable in those patients when access exists.
- An AEMT gives glucagon to an unconscious hypoglycemic patient. How does glucagon raise the blood glucose level?
- It moves glucose from the blood into cells like insulin
- It stimulates the liver to break down stored glycogen into glucose
- It blocks the kidneys from excreting glucose
- It directly adds sugar to the bloodstream as a concentrated solution
Correct answer: It stimulates the liver to break down stored glycogen into glucose
Glucagon raises blood glucose by stimulating the liver to break down stored glycogen into glucose (glycogenolysis) and release it into the bloodstream. Because it depends on the liver having glycogen stores, glucagon is less effective in malnourished or alcoholic patients. Insulin, by contrast, moves glucose into cells; glucagon is its counter-regulatory opposite.
- A patient found unresponsive has pinpoint pupils, a respiratory rate of 4, and track marks on the arms. Within the AEMT scope, what is the priority intervention?
- Give naloxone immediately and withhold ventilation
- Administer flumazenil to reverse the sedation
- Support ventilations with a bag-valve mask, then give naloxone
- Apply a non-rebreather mask and monitor only
Correct answer: Support ventilations with a bag-valve mask, then give naloxone
Supporting ventilations with a bag-valve mask while preparing and giving naloxone is the priority. Opioid overdose kills by respiratory depression, so oxygenation and ventilation come first; naloxone then reverses the opioid effect. Flumazenil reverses benzodiazepines, not opioids, and can trigger seizures. A non-rebreather mask alone cannot fix inadequate ventilation in an apneic patient.
- An AEMT prepares naloxone for a suspected opioid overdose with a respiratory rate of 5. Which dosing and goal statement is correct?
- Give 0.4 to 2 mg titrated to restore adequate breathing, not full alertness
- Give naloxone only after the patient is fully intubated
- Give naloxone subcutaneously and avoid the IM or IN routes
- Give a single fixed 10 mg dose and do not repeat
Correct answer: Give 0.4 to 2 mg titrated to restore adequate breathing, not full alertness
Naloxone 0.4 to 2 mg, titrated to restore adequate spontaneous breathing rather than full wakefulness, is the appropriate approach (intranasal dosing is typically 2-4 mg). Titrating to breathing avoids precipitating severe withdrawal and agitation. There is no fixed 10 mg cap, naloxone is given before any advanced airway when possible, and it is effective by IN, IM, or IV routes.
- An AEMT administers albuterol by nebulizer to a wheezing asthmatic. What is albuterol's mechanism of action?
- It stimulates beta-2 receptors, relaxing bronchial smooth muscle to dilate the airways
- It blocks histamine receptors to reduce airway swelling
- It thins mucus by breaking down its protein bonds
- It stimulates alpha-1 receptors to constrict blood vessels
Correct answer: It stimulates beta-2 receptors, relaxing bronchial smooth muscle to dilate the airways
Albuterol is a selective beta-2 agonist that stimulates beta-2 receptors on bronchial smooth muscle, causing it to relax and the airways to dilate (bronchodilation). This relieves wheezing and improves airflow in asthma and COPD. It does not block histamine, constrict vessels, or break down mucus.
- A 68-year-old with crushing chest pain asks the AEMT whether he can have nitroglycerin. Which finding is an absolute contraindication to giving it?
- Chest pain that has lasted 30 minutes
- Use of a phosphodiesterase-5 inhibitor such as sildenafil in the last 24-48 hours
- A history of stable angina controlled with nitroglycerin
- A heart rate of 88 beats per minute
Correct answer: Use of a phosphodiesterase-5 inhibitor such as sildenafil in the last 24-48 hours
Recent use of a phosphodiesterase-5 inhibitor (sildenafil, tadalafil, vardenafil) within 24-48 hours is an absolute contraindication because the combined vasodilation can cause profound, refractory hypotension. Other contraindications include hypotension (often a systolic below 90-100 mmHg). A prior history of using nitroglycerin and a normal heart rate are not contraindications.
- An AEMT is considering aspirin for a patient with suspected acute coronary syndrome. Which condition is a contraindication to giving aspirin?
- Chest pain radiating to the jaw
- A history of prior heart attack
- A known aspirin allergy or active GI/bleeding
- Mild nausea with the chest pain
Correct answer: A known aspirin allergy or active GI/bleeding
A known aspirin allergy or active gastrointestinal bleeding (or other significant active bleeding) is a contraindication to aspirin. Aspirin inhibits platelet aggregation, which is beneficial in a heart attack but harmful if the patient is bleeding or allergic. Radiating chest pain, a prior heart attack, and mild nausea are not reasons to withhold aspirin.
- A patient with widespread sepsis is warm, flushed, and hypotensive despite a normal-to-high heart rate. This presentation reflects which category of shock, and what is its underlying mechanism?
- Obstructive shock from a blocked great vessel
- Hypovolemic shock from blood loss
- Distributive shock from widespread vasodilation
- Cardiogenic shock from pump failure
Correct answer: Distributive shock from widespread vasodilation
This is distributive shock, caused by widespread vasodilation that drops vascular resistance and pools blood, leaving the core under-perfused despite a normal blood volume. Common causes include sepsis, anaphylaxis, and neurogenic (spinal) injury. Warm, flushed skin distinguishes early distributive shock from the cool, clamped-down skin of hypovolemic or cardiogenic shock.
- An AEMT reviews causes of distributive shock. Which group of conditions all produce this type of shock?
- Tension pneumothorax and cardiac tamponade
- Hemorrhage, severe vomiting, and burns
- Sepsis, anaphylaxis, and neurogenic (spinal cord) injury
- Massive heart attack and arrhythmia
Correct answer: Sepsis, anaphylaxis, and neurogenic (spinal cord) injury
Sepsis, anaphylaxis, and neurogenic spinal cord injury all cause distributive shock through abnormal widespread vasodilation and loss of vascular tone. Hemorrhage, vomiting, and burns cause hypovolemic shock; tension pneumothorax and tamponade cause obstructive shock; and a massive heart attack causes cardiogenic shock.
- An indication for intraosseous (IO) access by an AEMT is best described as which of the following?
- A patient with a fracture in the bone chosen for insertion
- Any patient who simply prefers not to have a peripheral IV
- A stable patient needing routine medication who has good veins
- A critically ill or arrested patient in whom rapid IV access cannot be obtained
Correct answer: A critically ill or arrested patient in whom rapid IV access cannot be obtained
Intraosseous access is indicated when a critically ill or arrested patient needs immediate vascular access but a peripheral IV cannot be quickly established. The marrow space provides a rapid route for fluids and medications. A fracture in the target bone is a contraindication, not an indication, and routine access in a stable patient with good veins does not justify an IO.
- A patient with a generalized tonic-clonic seizure is actively convulsing on the floor. What is the AEMT's most appropriate immediate action?
- Begin chest compressions during the convulsion
- Protect the patient from injury, do not restrain, and manage the airway after the seizure ends
- Hold the limbs firmly still to stop the movements
- Force a bite block or padded tongue depressor between the teeth
Correct answer: Protect the patient from injury, do not restrain, and manage the airway after the seizure ends
Protecting the patient from injury, not restraining them, and managing the airway and oxygenation once the seizure ends is the correct approach. Placing objects in the mouth can break teeth or obstruct the airway, and forcibly restraining limbs can cause injury. Chest compressions are not indicated for a seizing patient who has a pulse.
- A diabetic patient is post-seizure (postictal) and confused. What should the AEMT check early, since it is a common and reversible seizure cause?
- Pupil size only
- Capillary refill in the toes
- Skin turgor
- Blood glucose level
Correct answer: Blood glucose level
Checking the blood glucose level is essential because hypoglycemia is a common, rapidly reversible cause of seizures and altered mental status, especially in diabetics. Correcting a low glucose can resolve the seizure and prevent recurrence. Pupils, skin turgor, and capillary refill provide useful information but do not identify this treatable cause.
- An AEMT is asked to guide the routine, uncomplicated delivery of a baby whose head is crowning. Which sequence of steps is correct?
- Pull firmly on the head to speed delivery of the shoulders
- Support the head as it delivers, check for a cord around the neck, guide the shoulders, then keep the newborn warm and dry
- Push on the mother's abdomen to expel the baby quickly
- Have the mother stand and walk to encourage delivery
Correct answer: Support the head as it delivers, check for a cord around the neck, guide the shoulders, then keep the newborn warm and dry
The correct sequence is to support the head as it emerges, check for a nuchal cord, gently guide the shoulders out one at a time, then dry, warm, and stimulate the newborn. Controlled support prevents tearing and injury. Pulling on the head, pushing on the abdomen (fundal pressure), or having the mother stand are all unsafe.
- After delivery of the head, the AEMT finds the umbilical cord looped once, loosely, around the newborn's neck. What is the most appropriate first action?
- Push the head back to relieve the loop
- Immediately clamp and cut the cord before the body delivers
- Apply traction to the cord to free it
- Gently slip the loop of cord over the baby's head
Correct answer: Gently slip the loop of cord over the baby's head
Gently slipping the loose loop of cord over the baby's head is the first action for a nuchal cord. This relieves the loop without interrupting blood flow. Clamping and cutting before delivery is reserved for a tight cord that cannot be reduced. Pulling on the cord can tear it or detach the placenta, and pushing the head back is harmful.
- After delivering the head, the AEMT finds a nuchal cord wrapped tightly and unable to be slipped over the head, blocking delivery of the body. What should be done next?
- Apply strong traction to the baby's head to force delivery
- Continue waiting indefinitely for the cord to loosen on its own
- Reach in and manually deliver the placenta first
- Place two clamps on the cord, cut between them, and complete delivery
Correct answer: Place two clamps on the cord, cut between them, and complete delivery
When a nuchal cord is too tight to reduce over the head and is preventing delivery, the cord should be double-clamped and cut between the clamps so the body can deliver. Leaving a tight cord in place can strangle or asphyxiate the infant. Forced traction risks brachial plexus or cord injury, and the placenta is never delivered manually before the baby.
- An AEMT must calculate a newborn's Apgar score at one minute. Which five components are scored?
- Appearance (color), Pulse, Grimace (reflex), Activity (tone), and Respiration
- Eye opening, verbal response, motor response, pupils, and gag
- Blood pressure, glucose, temperature, weight, and length
- Airway, Breathing, Circulation, Disability, and Exposure
Correct answer: Appearance (color), Pulse, Grimace (reflex), Activity (tone), and Respiration
The Apgar score uses Appearance (skin color), Pulse (heart rate), Grimace (reflex irritability), Activity (muscle tone), and Respiration (respiratory effort). The letters of the name Apgar map to these five items. ABCDE is a trauma assessment, and eye/verbal/motor responses belong to the Glasgow Coma Scale, not the Apgar.
- A newborn at one minute has a pink body with blue hands and feet, a heart rate of 120, vigorous crying, active motion, and a grimace with suction. What is the Apgar score?
Correct answer: 8
The Apgar score is 8. Acrocyanosis (pink body, blue extremities) scores 1 for Appearance, and a grimace alone (without cough, sneeze, or vigorous cry) scores 1 for reflex irritability. The other three components each score 2 — heart rate above 100, vigorous crying for respirations, and active motion for tone. Summing 1 plus 2 plus 1 plus 2 plus 2 gives 8.
- A newborn one minute after birth has a heart rate of 90, slow irregular breathing, some flexion of the limbs, a grimace to stimulation, and a body that is blue all over. What is the Apgar score?
Correct answer: 4
The Apgar score is 4. A heart rate under 100 scores 1, slow/irregular respirations score 1, some flexion of limbs scores 1, grimace scores 1, and blue/pale color scores 0, totaling 4. A score in the 0-3 range is critically low and 4-6 is moderately depressed, so this newborn needs active resuscitation and reassessment.
- After delivery, the mother continues to bleed heavily and her uterus feels soft and boggy. After the placenta has delivered, what is the most appropriate AEMT intervention to control postpartum hemorrhage?
- Pack the vagina tightly with gauze to tamponade the bleeding
- Perform firm fundal (uterine) massage and allow the infant to breastfeed
- Have the mother sit fully upright and bear down
- Apply a tourniquet around the lower abdomen
Correct answer: Perform firm fundal (uterine) massage and allow the infant to breastfeed
Firm fundal massage, along with encouraging breastfeeding, is the first-line field treatment for postpartum hemorrhage because it stimulates the uterus to contract and clamp down on bleeding vessels (uterine atony is the leading cause). Packing the vagina, applying an abdominal tourniquet, and having the mother bear down do not control the bleeding and may cause harm.
- An AEMT manages a postpartum hemorrhage with ongoing heavy bleeding despite fundal massage. Within the AEMT scope, what additional supportive measures are most appropriate?
- Treat for shock with oxygen, IV fluids, warmth, and rapid transport
- Withhold IV fluids to avoid diluting clotting factors
- Delay transport until the bleeding fully stops
- Place the mother in a seated position and observe
Correct answer: Treat for shock with oxygen, IV fluids, warmth, and rapid transport
Treating for shock — oxygen, IV fluid resuscitation, keeping the patient warm, and rapid transport — is the appropriate AEMT response when bleeding continues despite massage. Postpartum hemorrhage can rapidly cause hypovolemic shock. Withholding fluids, sitting the patient up, or delaying transport all worsen perfusion and outcomes.
- A 26-year-old woman with a positive pregnancy test and a missed period presents with sharp one-sided lower abdominal pain, light vaginal spotting, and dizziness. Her skin is pale and her pulse is 118. What condition should the AEMT most suspect?
- A urinary tract infection
- Ruptured ectopic pregnancy with internal bleeding
- Normal early-pregnancy discomfort
- Ovarian cyst that has fully resolved
Correct answer: Ruptured ectopic pregnancy with internal bleeding
A ruptured ectopic pregnancy is most likely: a positive pregnancy test with unilateral lower abdominal pain, spotting, and signs of shock (pallor, tachycardia, dizziness) points to bleeding from a pregnancy implanted outside the uterus. This is life-threatening and requires high-flow oxygen, shock treatment, and rapid transport, not reassurance as for normal pregnancy.
- A woman of childbearing age reports sudden severe lower abdominal pain and the AEMT is building a gynecologic history. Which question is most relevant to identifying a possible ectopic pregnancy or other obstetric cause?
- Have you ever broken a bone?
- When did you last have a tetanus shot?
- When was your last menstrual period, and is there any chance you are pregnant?
- Do you have any food allergies?
Correct answer: When was your last menstrual period, and is there any chance you are pregnant?
Asking about the last menstrual period and the possibility of pregnancy is most relevant, because pregnancy status fundamentally changes the differential for lower abdominal pain in a woman of childbearing age and flags emergencies like ectopic pregnancy. Bone fractures, food allergies, and tetanus status do not help identify an obstetric or gynecologic cause.
- A pregnant woman in her third trimester becomes lightheaded, pale, and hypotensive while lying flat on her back on the stretcher. What is the most appropriate immediate action?
- Tilt her onto her left side (or place padding under the right hip)
- Administer nitroglycerin for the low blood pressure
- Sit her fully upright and have her hold her breath
- Raise both legs straight up and keep her flat
Correct answer: Tilt her onto her left side (or place padding under the right hip)
Tilting the patient onto her left side, or placing padding under her right hip, relieves supine hypotensive syndrome. Late in pregnancy the heavy uterus compresses the inferior vena cava when she lies flat, reducing blood return to the heart. Left-lateral positioning shifts the uterus off the vessel and restores blood pressure; nitroglycerin would worsen the hypotension.
- An AEMT responds to a generalized seizure in a 35-week-pregnant woman with a known history of high blood pressure and swelling. Which condition is the most likely cause?
- Hypoglycemia from fasting
- A simple faint
- Heat stroke
- Eclampsia
Correct answer: Eclampsia
Eclampsia is most likely: a seizure in a late-pregnancy patient with preexisting hypertension and edema reflects severe pre-eclampsia progressing to eclamptic seizures. Management focuses on a calm, low-stimulation environment, airway protection, left-lateral positioning, and rapid transport. While hypoglycemia should always be checked, the hypertension and edema point specifically to eclampsia.
- An AEMT is monitoring a patient with severe pre-eclampsia to anticipate progression. Which finding most suggests imminent eclamptic seizure?
- A gradual decrease in blood pressure to normal
- Mild ankle swelling that improves with elevation
- Severe headache, visual disturbances, and upper-abdominal pain
- Occasional Braxton-Hicks contractions
Correct answer: Severe headache, visual disturbances, and upper-abdominal pain
A severe headache, visual changes (such as flashing lights or blurring), and right-upper-quadrant or epigastric pain are warning signs that severe pre-eclampsia may progress to seizures. These symptoms reflect worsening end-organ involvement. Normalizing blood pressure, mild positional swelling, and Braxton-Hicks contractions are not warning signs of impending eclampsia.
- A diabetic taking insulin tells the AEMT he took his usual morning insulin but skipped breakfast because he felt nauseated. He is now sweaty and confused. What does this history most strongly suggest?
- Diabetic ketoacidosis from too little insulin
- A stroke unrelated to his diabetes
- Simple dehydration
- Hypoglycemia from insulin without food intake
Correct answer: Hypoglycemia from insulin without food intake
Hypoglycemia is most likely: taking insulin without eating drives glucose down, producing diaphoresis and confusion. The history of insulin plus a missed meal is a classic setup for a low blood sugar. Checking a finger-stick glucose confirms it, and the patient should receive oral glucose if able to swallow or IV dextrose/IM glucagon if not.
- An AEMT is dispatched for an altered diabetic. Which assessment finding best distinguishes hyperglycemic crisis (such as diabetic ketoacidosis) from hypoglycemia?
- Deep, rapid breathing with a fruity breath odor and warm, dry skin
- Tremor and palpitations that resolve quickly with sugar
- Sudden confusion immediately after an insulin dose
- Cool, diaphoretic skin with rapid onset of symptoms
Correct answer: Deep, rapid breathing with a fruity breath odor and warm, dry skin
Deep, rapid (Kussmaul) breathing with a fruity acetone breath odor and warm, dry skin points to hyperglycemic crisis such as diabetic ketoacidosis, which develops over hours to days. Hypoglycemia instead causes cool, sweaty skin with rapid onset, tremor, and palpitations that improve with sugar. A finger-stick glucose confirms which direction the patient is in.
- A patient presents with sudden facial droop, slurred speech, and one-sided arm weakness that began 45 minutes ago. After supporting the airway, what is the AEMT's most important time-sensitive action?
- Delay transport until symptoms either worsen or improve
- Encourage the patient to lie flat and sleep it off
- Give aspirin to dissolve the clot before arrival
- Document the time of symptom onset and transport rapidly to a stroke center
Correct answer: Document the time of symptom onset and transport rapidly to a stroke center
Documenting the exact time of symptom onset (or last known well) and transporting rapidly to a stroke-capable hospital is most important, because eligibility for clot-busting and clot-removal therapy depends on time windows. Aspirin is not given for undifferentiated stroke prehospitally because the type (clot versus bleed) is unknown. Delaying transport wastes the treatment window.
- An AEMT is treating an asthmatic in moderate distress with audible wheezing and good air movement. Which AEMT-scope medication is most appropriate to relieve the bronchospasm?
- Aspirin by mouth
- Oral glucose
- Albuterol by nebulizer or metered-dose inhaler
- Naloxone intranasally
Correct answer: Albuterol by nebulizer or metered-dose inhaler
Albuterol delivered by nebulizer or metered-dose inhaler is the appropriate treatment because it is a beta-2 agonist that relaxes bronchial smooth muscle and relieves wheezing. Naloxone reverses opioids, oral glucose treats hypoglycemia, and aspirin is for suspected cardiac chest pain — none of which address bronchospasm.
- An adult with crushing substernal chest pain has a blood pressure of 142/88 and no contraindications. Within the AEMT scope, which two medications are most appropriate to consider?
- Dextrose and epinephrine 1:10,000
- Albuterol and oral glucose
- Aspirin (chewed) and nitroglycerin
- Naloxone and glucagon
Correct answer: Aspirin (chewed) and nitroglycerin
Chewed aspirin and nitroglycerin are the appropriate considerations for suspected cardiac chest pain within the AEMT scope: aspirin inhibits platelet clumping and nitroglycerin dilates vessels to reduce cardiac workload, provided the blood pressure is adequate and there is no recent erectile-dysfunction drug use. The other pairs treat opioid overdose, asthma/hypoglycemia, or cardiac arrest, not chest pain.
- An AEMT considers giving nitroglycerin to a chest-pain patient whose blood pressure is 84/52 mmHg. What is the most appropriate action?
- Give a double dose because of the low pressure
- Give nitroglycerin to raise the blood pressure
- Give nitroglycerin only if the heart rate is also low
- Withhold nitroglycerin because the patient is hypotensive
Correct answer: Withhold nitroglycerin because the patient is hypotensive
Nitroglycerin should be withheld because the patient is hypotensive (systolic below the typical 90-100 mmHg threshold). Nitroglycerin is a vasodilator that lowers blood pressure further and could cause collapse. It does not raise blood pressure, and there is no scenario in which doubling the dose in a hypotensive patient is correct.
- An AEMT assists a multigravida with an imminent delivery; the head delivers but the anterior shoulder fails to emerge with the next contraction (shoulder dystocia). What is the most appropriate first maneuver?
- Push on the top of the uterus (fundal pressure)
- Hyperflex the mother's hips with knees toward her chest (McRoberts position)
- Pull firmly down on the baby's head
- Have the mother bear down harder while sitting up
Correct answer: Hyperflex the mother's hips with knees toward her chest (McRoberts position)
The McRoberts maneuver — sharply flexing the mother's hips so her knees come toward her chest — is the appropriate first step for shoulder dystocia because it rotates the pelvis and frees the trapped anterior shoulder. Strong traction on the head risks nerve injury, fundal pressure can worsen the impaction, and having her sit and push does not relieve the dystocia.
- A woman experiencing imminent delivery tells the AEMT she is HIV-positive. How should this affect the AEMT's field management of the delivery?
- Refuse to assist with the delivery to avoid exposure
- Delay all care until a specialized team arrives
- Avoid touching the newborn after delivery
- Use full standard body-substance isolation and deliver normally, as for any birth
Correct answer: Use full standard body-substance isolation and deliver normally, as for any birth
The AEMT should use full standard body-substance isolation — gloves, gown, eye protection, and mask — and proceed with a normal delivery, just as with any birth. Standard precautions protect the provider regardless of known or unknown infection status, and they treat every patient's body fluids as potentially infectious. Refusing care, delaying delivery of an imminent birth, or neglecting the newborn would all be negligent and dangerous.
- An AEMT is treating a newborn who, after drying, warming, and stimulation, has a heart rate of 80 and weak, gasping respirations. Within the AEMT scope, what is the priority intervention?
- Begin chest compressions immediately without ventilating
- Withhold all support and reassess in five minutes
- Begin positive-pressure ventilation with a bag-valve mask at 40-60 breaths per minute
- Administer epinephrine to the newborn
Correct answer: Begin positive-pressure ventilation with a bag-valve mask at 40-60 breaths per minute
Positive-pressure ventilation with a bag-valve mask is the priority because a newborn heart rate below 100 with inadequate breathing is driven by hypoxia, and effective ventilation is the single most important resuscitation step for a newborn. Chest compressions are added only if the heart rate stays below 60 despite good ventilation, and giving epinephrine to the newborn is beyond the typical AEMT scope.
- An AEMT establishes an IV on an unresponsive 58-year-old man whose blood glucose reads 38 mg/dL. A family member reports he drinks heavily, eats poorly, and has not had a real meal in days. The AEMT is deciding between intravenous dextrose and intramuscular glucagon. Which factor makes intravenous dextrose the clearly better choice for this patient?
- Glucagon raises blood sugar by mobilizing stored liver glycogen, which is likely depleted in a chronically malnourished, alcohol-using patient
- Glucagon cannot be given to anyone who already has IV access in place
- Dextrose is the only medication an AEMT is permitted to give for low blood sugar
- Glucagon works only in patients younger than 50 years of age
Correct answer: Glucagon raises blood sugar by mobilizing stored liver glycogen, which is likely depleted in a chronically malnourished, alcohol-using patient
Intravenous dextrose is preferred because glucagon raises blood sugar by triggering the liver to break down stored glycogen, and a chronically malnourished, heavy-drinking patient is likely to have little or no glycogen left for glucagon to mobilize. Dextrose supplies glucose directly to the bloodstream and works regardless of liver stores, so when an AEMT already has IV or IO access, dextrose is the more reliable correction. Glucagon is reserved mainly for hypoglycemic patients when vascular access cannot be obtained.
- An AEMT is called for a 25-year-old who ate shellfish 20 minutes ago and broke out in itchy hives across the trunk. She is breathing comfortably with clear lungs, speaks in full sentences, has no lip or tongue swelling, and her blood pressure is 124/78 with a heart rate of 84. What does this presentation most accurately represent, and how should the AEMT respond?
- Early anaphylaxis requiring immediate intramuscular epinephrine before any other step
- Anaphylactic shock requiring a rapid fluid bolus and epinephrine
- A condition outside the scope of EMS that requires no assessment or transport
- A localized skin (single-system) allergic reaction; monitor closely, support as needed, and transport, reserving epinephrine for signs of airway, breathing, or circulatory involvement
Correct answer: A localized skin (single-system) allergic reaction; monitor closely, support as needed, and transport, reserving epinephrine for signs of airway, breathing, or circulatory involvement
This is a localized, single-system allergic reaction limited to the skin, so the AEMT should monitor the patient closely and transport, holding intramuscular epinephrine unless airway, breathing, or circulatory signs develop. Anaphylaxis is defined by involvement of two or more body systems or by airway, respiratory, or cardiovascular compromise such as wheezing, throat or tongue swelling, or hypotension. Because this patient has only isolated hives with normal breathing and vital signs, epinephrine is not yet indicated, but vigilant reassessment is essential because allergic reactions can progress quickly.
- An AEMT assesses a 29-year-old woman at 34 weeks gestation with a headache and right upper-quadrant discomfort. She has had no seizure. Her blood pressure on two readings five minutes apart is 168/110 and 172/108. Which finding in this scenario most clearly identifies a hypertensive emergency of pregnancy (severe preeclampsia) requiring expedited transport?
- A blood glucose level of 96 mg/dL
- A heart rate of 88 beats per minute
- A persistently elevated systolic pressure at or above roughly 160 mmHg and diastolic at or above roughly 110 mmHg
- A respiratory rate of 16 breaths per minute
Correct answer: A persistently elevated systolic pressure at or above roughly 160 mmHg and diastolic at or above roughly 110 mmHg
The hallmark of severe preeclampsia in this patient is the persistently elevated blood pressure, with systolic readings at or above about 160 mmHg and diastolic at or above about 110 mmHg confirmed on repeat measurement. Severe-range hypertension in the second half of pregnancy, especially with symptoms like headache or right upper-quadrant pain, signals high risk of progression to eclamptic seizures and warrants prompt transport with the patient positioned to avoid supine hypotension. The normal heart rate, respiratory rate, and glucose do not define the emergency.
- During a field delivery, the head delivers and the AEMT finds the umbilical cord wrapped tightly around the newborn's neck. The AEMT cannot slip it back over the head despite a careful attempt. What is the most appropriate next action?
- Place two clamps on the cord, cut between them, then unwrap it and continue the delivery
- Push the head back into the birth canal and wait for hospital arrival
- Leave the tight cord in place and deliver the body through it
- Apply firm traction on the cord to pull the loop free
Correct answer: Place two clamps on the cord, cut between them, then unwrap it and continue the delivery
When a nuchal cord is too tight to gently slip over the newborn's head, the correct step is to place two clamps on the cord, cut between them, and then unwrap the cord so delivery can proceed. A tight cord that is left in place can be compressed or torn as the body delivers, cutting off the newborn's oxygen supply. Pushing the head back or applying traction on the cord can cause serious harm, so clamping and cutting is the safe way to free a non-reducible nuchal cord.
- An AEMT is assisting a 60-year-old man with crushing chest pressure who has his own prescribed sublingual nitroglycerin. After confirming there is no recent erectile-dysfunction drug use, the AEMT checks a blood pressure of 138/86 and gives one dose. The chest pain persists three minutes later. Before assisting with a second nitroglycerin dose, what must the AEMT do?
- Give two doses back to back without rechecking anything to relieve the pain faster
- Recheck the blood pressure and withhold the next dose if the systolic pressure has dropped too low (commonly below about 100 mmHg)
- Switch to giving the nitroglycerin by mouth to be swallowed instead of under the tongue
- Administer the next dose only after 30 minutes have passed
Correct answer: Recheck the blood pressure and withhold the next dose if the systolic pressure has dropped too low (commonly below about 100 mmHg)
Before each additional nitroglycerin dose the AEMT must recheck the blood pressure and withhold the medication if the systolic pressure has fallen too low, commonly below about 100 mmHg per local protocol. Nitroglycerin is a vasodilator and can cause significant hypotension, so doses are typically spaced about five minutes apart up to roughly three total, with a blood-pressure check before each one. Stacking doses without reassessing pressure risks dangerous hypotension, and swallowing the tablet or waiting 30 minutes are not correct administration practices.
- An AEMT responds for a 72-year-old woman with sudden left-sided weakness and slurred speech. The AEMT confirms the deficits and a normal blood glucose. Beyond completing a stroke screen, which piece of information is most important for the AEMT to obtain and report to the receiving stroke center?
- The brand of the patient's blood pressure medication
- The exact time the patient was last known to be well (without symptoms)
- The patient's favorite hand for writing
- The patient's childhood immunization history
Correct answer: The exact time the patient was last known to be well (without symptoms)
The most important additional information is the exact time the patient was last known to be well, meaning the last moment she was seen without symptoms. Time-sensitive stroke treatments such as clot-dissolving therapy are guided by this window, so an accurate last-known-well time directly drives hospital destination and treatment decisions. Confirming the deficits and ruling out low blood sugar (which can mimic stroke) is important, but capturing and relaying the onset time is what allows the stroke center to act quickly.
- An AEMT responds to a 70-year-old man who has vomited dark material that looks like coffee grounds and reports several days of black, tarry stools. He is pale and diaphoretic with a heart rate of 122 and a blood pressure of 86/54. Which problem should the AEMT suspect, and what is the priority?
- A simple stomach virus; encourage oral fluids and arrange routine transport
- An allergic reaction; administer intramuscular epinephrine
- Constipation; reassure the patient and recommend follow-up with his physician
- An upper gastrointestinal bleed with hypovolemic shock; protect the airway, position appropriately, and provide rapid transport with shock management
Correct answer: An upper gastrointestinal bleed with hypovolemic shock; protect the airway, position appropriately, and provide rapid transport with shock management
An upper gastrointestinal bleed with hypovolemic shock is the concern, because coffee-ground emesis and black tarry stools (melena) signal digested blood, and the fast heart rate with low blood pressure shows the patient is losing volume. The priority is airway protection against aspiration, shock management with positioning and fluids per protocol, and rapid transport. This is not a virus, an allergic reaction, or simple constipation.
- An AEMT assesses a 68-year-old man with sudden, severe abdominal and lower back pain. On palpation there is a pulsating mass in the mid-abdomen, and his blood pressure is 84/50 with a heart rate of 120. What should the AEMT suspect, and how should the abdomen be examined?
- Gallbladder disease; press deeply in the right upper quadrant to confirm tenderness
- A kidney stone; palpate the mass firmly to assess its size before transport
- A leaking abdominal aortic aneurysm; avoid deep or repeated palpation of the mass and provide rapid transport with shock care
- Simple muscle strain; apply heat and delay transport
Correct answer: A leaking abdominal aortic aneurysm; avoid deep or repeated palpation of the mass and provide rapid transport with shock care
A leaking abdominal aortic aneurysm is the suspicion, because a pulsatile mid-abdominal mass with sudden tearing pain and signs of shock points to a weakened, bleeding aorta. The AEMT should avoid deep or repeated palpation, which could worsen a rupture, and instead provide gentle handling, shock management, and rapid transport. This is not a kidney stone, muscle strain, or gallbladder disease requiring firm palpation.
- An AEMT is called for a 45-year-old non-pregnant woman with heavy vaginal bleeding that has soaked several pads per hour. She is pale, cool, and lightheaded with a heart rate of 116 and a blood pressure of 90/58. What is the most appropriate AEMT management?
- Withhold all treatment until the cause of bleeding is identified at the hospital
- Treat for hypovolemic shock with positioning, oxygen as needed, IV access and fluids per protocol, and prompt transport while estimating blood loss
- Pack the vagina with gauze to stop the bleeding internally
- Give intramuscular epinephrine to raise the blood pressure
Correct answer: Treat for hypovolemic shock with positioning, oxygen as needed, IV access and fluids per protocol, and prompt transport while estimating blood loss
Treating for hypovolemic shock is correct, because heavy gynecological bleeding with pallor, low blood pressure, and a fast heart rate means the patient is losing significant volume regardless of the cause. The AEMT should manage shock with positioning, oxygen as needed, IV fluids per protocol, and prompt transport, while counting pads to estimate loss. Internal vaginal packing is not within prehospital practice, treatment should not be delayed, and epinephrine is not indicated.
- An AEMT assesses an 80-year-old nursing home patient with a productive cough and fever who is now confused, with a temperature of 102.6 F, a respiratory rate of 26, a heart rate of 118, and a blood pressure of 88/52. Which condition best fits this picture, and what should the AEMT do?
- Sepsis from a likely infection; recognize early, support perfusion with fluids per protocol, and transport urgently to a capable facility
- Dehydration only; give oral fluids and leave the patient at home
- A panic attack; coach slow breathing and cancel transport
- Normal aging; no urgent intervention is needed
Correct answer: Sepsis from a likely infection; recognize early, support perfusion with fluids per protocol, and transport urgently to a capable facility
Sepsis from a likely infection is the best fit, because the combination of a known infection source, fever, fast breathing, fast heart rate, low blood pressure, and new confusion reflects a body-wide response to infection with poor perfusion. The AEMT should recognize it early, support perfusion with fluids per protocol, and transport urgently. This is not normal aging, a panic attack, or simple dehydration that can be managed at home.
- An AEMT responds to a 30-year-old who briefly fainted at church and is now awake and alert with normal vital signs. He recalls feeling warm and lightheaded just before collapsing. What is the most appropriate AEMT approach to this syncopal episode?
- Keep the patient lying flat or with legs elevated, obtain a full set of vitals and a blood glucose, perform a cardiac and neurologic assessment, and encourage transport for evaluation
- Have the patient stand and walk immediately to prove he has recovered
- Refuse transport because the patient is now awake and feels fine
- Administer intramuscular epinephrine to prevent another episode
Correct answer: Keep the patient lying flat or with legs elevated, obtain a full set of vitals and a blood glucose, perform a cardiac and neurologic assessment, and encourage transport for evaluation
Keeping the patient supine or with legs elevated and completing a thorough assessment is the correct approach, because syncope can have benign or dangerous causes such as a cardiac dysrhythmia, low blood sugar, or bleeding, so vitals, glucose, and a cardiac and neurologic exam are essential. Transport for further evaluation is appropriate even when the patient feels recovered. Refusing transport, forcing the patient to stand, and giving epinephrine are all inappropriate.
- An AEMT is called for a 24-year-old who is about 9 weeks pregnant and reports lower abdominal cramping with moderate vaginal bleeding and the passage of tissue. Her heart rate is 104 and blood pressure is 104/66. What should the AEMT suspect, and what is the appropriate care?
- Active labor; prepare for an imminent delivery of a full-term infant
- A possible spontaneous abortion (miscarriage); provide emotional support, save any passed tissue for the hospital, monitor for shock, and transport
- An allergic reaction; administer intramuscular epinephrine
- Normal pregnancy; reassure her and cancel transport
Correct answer: A possible spontaneous abortion (miscarriage); provide emotional support, save any passed tissue for the hospital, monitor for shock, and transport
A possible spontaneous abortion is the suspicion, because early pregnancy bleeding with cramping and passage of tissue commonly reflects a miscarriage. The AEMT should provide emotional support, bring any passed tissue to the hospital for evaluation, watch closely for signs of shock from blood loss, and transport. This is not a normal finding to dismiss, not full-term labor at 9 weeks, and not an allergic reaction.
- An AEMT arrives to find an 18-month-old who had a brief generalized seizure at home in the setting of a fever of 103 F. The child is now postictal but breathing adequately with a patent airway. What is the most appropriate AEMT management of this febrile seizure?
- Protect the airway, keep the child positioned safely, allow gradual cooling by removing excess clothing, monitor airway and breathing, and transport for evaluation
- Refuse transport because febrile seizures are always harmless
- Submerge the child in ice water to rapidly lower the temperature
- Restrain the child tightly and force a bite block into the mouth
Correct answer: Protect the airway, keep the child positioned safely, allow gradual cooling by removing excess clothing, monitor airway and breathing, and transport for evaluation
Protecting the airway and allowing gentle cooling is correct, because most febrile seizures in young children are brief and self-limited, so management centers on airway and breathing, safe positioning, removing excess clothing to cool gradually, and transport for evaluation of the underlying illness. Forcing objects into the mouth, refusing transport, and ice-water immersion are all unsafe and inappropriate.
- An AEMT is treating a known type 1 diabetic with suspected diabetic ketoacidosis who has a glucose meter reading of HIGH, deep rapid breathing, and dry skin. He is hypotensive and severely dehydrated. Within the AEMT scope, what is the most appropriate prehospital treatment?
- Withhold all fluids until insulin can be administered
- Establish IV access and give isotonic fluids per protocol to support perfusion, provide oxygen as needed, and transport promptly
- Give oral glucose to correct the high blood sugar
- Administer subcutaneous insulin to lower the blood sugar in the field
Correct answer: Establish IV access and give isotonic fluids per protocol to support perfusion, provide oxygen as needed, and transport promptly
Establishing IV access and giving isotonic fluids per protocol is correct, because diabetic ketoacidosis causes profound dehydration, so fluid resuscitation to support perfusion is the key prehospital intervention along with oxygen as needed and prompt transport. Insulin is not in the AEMT scope and is given in the hospital, oral glucose would worsen the already high sugar, and withholding fluids would worsen the dehydration.
- An AEMT arrives first at a two-car collision with three patients and a fuel leak under one vehicle. Following the standard scene size-up sequence, after confirming the scene is unsafe to enter, which component should the AEMT address next before approaching any patient?
- Determine the mechanism of injury and the number of patients while staging at a safe distance
- Begin a primary assessment on the most seriously injured patient
- Document each patient's past medical history
- Apply a tourniquet to anyone with visible bleeding
Correct answer: Determine the mechanism of injury and the number of patients while staging at a safe distance
Determining the mechanism of injury and number of patients while staging at a safe distance is correct. Scene size-up has five components: scene safety, standard precautions, mechanism of injury or nature of illness, number of patients, and the need for additional resources. These are completed before patient contact because the MOI and patient count drive resource requests. Starting a primary assessment or applying a tourniquet requires entering an unsafe scene, which is premature until hazards are controlled.
- During scene size-up at a residential overdose call, the AEMT pauses at the doorway to don gloves and eye protection before touching the patient. Which size-up component does this action satisfy?
- Standard precautions (body substance isolation)
- Resource determination
- Establishing incident command
- Mechanism of injury determination
Correct answer: Standard precautions (body substance isolation)
Donning gloves and eye protection satisfies the standard precautions (body substance isolation) component of scene size-up. Standard precautions protect the provider from blood and body fluids and must be selected based on the anticipated exposure before patient contact. Mechanism of injury describes how an injury occurred, resource determination addresses whether more help is needed, and incident command is an organizational structure, not a personal-protection step.
- After scene size-up is complete and the AEMT reaches an unresponsive adult, what is the FIRST element of the primary assessment the AEMT should establish?
- Baseline vital signs with a manual blood pressure
- A general impression of the patient and level of responsiveness
- A 12-lead interpretation
- A detailed SAMPLE history
Correct answer: A general impression of the patient and level of responsiveness
Forming a general impression and assessing level of responsiveness is the first element of the primary assessment. The primary assessment is designed to find and treat immediate life threats in order: general impression and mental status (often with AVPU), then airway, breathing, and circulation. A SAMPLE history and baseline vitals belong to the secondary assessment, and a 12-lead is beyond the primary assessment's life-threat focus.
- The purpose of the primary assessment in EMS is best described as which of the following?
- Obtaining a complete set of vital signs and a focused history
- Identifying and immediately treating life-threatening problems with airway, breathing, and circulation
- Cataloging every injury found during a head-to-toe exam
- Determining the patient's insurance and transport destination
Correct answer: Identifying and immediately treating life-threatening problems with airway, breathing, and circulation
Identifying and immediately treating life-threatening problems with airway, breathing, and circulation is the purpose of the primary assessment. It is a rapid evaluation that follows the ABC priorities so that critical interventions, such as opening an airway or controlling major bleeding, happen before any detailed exam. A complete set of vitals and a head-to-toe survey are part of the secondary assessment, performed after life threats are managed.
- At a mass casualty incident the AEMT is assigned to triage using the START system. A patient is breathing at 36 breaths per minute. Without checking anything else, how should this patient be categorized?
- Immediate (red)
- Minor (green)
- Expectant (black)
- Delayed (yellow)
Correct answer: Immediate (red)
A patient breathing faster than 30 breaths per minute is tagged Immediate (red) under START. START evaluates respirations, perfusion, and mental status (RPM); a respiratory rate over 30 indicates a critical physiologic problem and stops further assessment for tagging purposes. Delayed and minor categories require respirations of 30 or fewer with adequate perfusion and mental status, and expectant applies only to patients who do not breathe after a single airway-repositioning attempt.
- While performing START triage, the AEMT finds a non-ambulatory patient who is breathing at 24 per minute but has a capillary refill time of greater than 2 seconds (or no palpable radial pulse). What is the correct triage category?
- Delayed (yellow)
- Minor (green)
- Immediate (red)
- Expectant (black)
Correct answer: Immediate (red)
This patient is tagged Immediate (red). In START, after respirations are confirmed at 30 or fewer, perfusion is checked; capillary refill longer than 2 seconds or an absent radial pulse signals inadequate perfusion and an Immediate tag, regardless of a normal respiratory rate. Delayed and minor require adequate perfusion and the ability to follow commands, and expectant is reserved for patients who cannot be made to breathe.
- An AEMT begins START triage at a building collapse. What is the very first action used to rapidly separate the least injured patients from the rest?
- Check each patient's radial pulse
- Count each patient's respiratory rate
- Direct everyone who can walk to move to a designated collection area
- Open the airway of every supine patient
Correct answer: Direct everyone who can walk to move to a designated collection area
Directing everyone who can walk to move to a designated collection area is the first step of START. Ambulatory patients are tagged Minor (green) because the ability to walk on command demonstrates adequate airway, breathing, perfusion, and mental status. Only after the walking wounded are separated does the rescuer assess the remaining patients individually for respirations, perfusion, and mental status.
- During START triage the AEMT reaches a patient who is not breathing. After a single attempt to open and reposition the airway, the patient still does not breathe. How should this patient be triaged?
- Expectant or deceased (black)
- Delayed (yellow), and reassess later
- Minor (green)
- Immediate (red), and begin rescue breathing
Correct answer: Expectant or deceased (black)
This patient is triaged Expectant or deceased (black). In START, if a patient is apneic and does not begin breathing after one airway-opening maneuver, no further resuscitation is attempted during initial triage because resources must be directed to salvageable patients. A patient who does begin breathing after the airway is opened is instead tagged Immediate (red); START does not include sustained rescue breathing during the triage sweep.
- At a multi-vehicle crash, the first-arriving AEMT crew establishes command, requests additional units, and assigns arriving responders specific roles to keep the number of people reporting to any one supervisor manageable. Which Incident Command System concept is being applied when responders are organized so each supervisor oversees roughly three to seven subordinates?
- Demobilization
- Unified command
- Mutual aid
- Span of control
Correct answer: Span of control
Limiting how many responders report to a single supervisor reflects span of control. The Incident Command System recommends a span of control of about three to seven subordinates per supervisor, with five being optimal, to maintain effective supervision and communication. Unified command refers to multiple agencies sharing command authority, mutual aid is assistance from outside agencies, and demobilization is the orderly release of resources as an incident winds down.
- An AEMT arrives to find a 24-year-old man who collapsed at a restaurant. He is awake but anxious, has audible wheezing, hives spreading across his chest, and swelling of his lips. He says his throat 'feels tight' and reports a known shellfish allergy. After ensuring the airway is patent and applying oxygen, what is the single most important next intervention?
- Give a nebulized bronchodilator and reassess the wheezing in 5 minutes
- Administer epinephrine 0.3 mg of the 1 mg/mL (1:1,000) concentration intramuscularly into the lateral thigh
- Place the patient supine and request paramedic intercept before treating
- Establish an IV line and run a fluid bolus before any medication
Correct answer: Administer epinephrine 0.3 mg of the 1 mg/mL (1:1,000) concentration intramuscularly into the lateral thigh
Administering intramuscular epinephrine 0.3 mg of the 1 mg/mL (1:1,000) concentration into the lateral thigh is the priority. Airway swelling, hives, and bronchospasm together indicate anaphylaxis, and IM epinephrine is the only intervention that reverses the underlying systemic reaction. A nebulized bronchodilator treats only the wheezing and delays the definitive drug, and waiting for an IV or paramedics costs critical time when the airway is already threatened.
- A 58-year-old woman reports sudden crushing chest pressure radiating to her left arm for 20 minutes, with nausea and diaphoresis. Her blood pressure is 138/84, heart rate 92, and oxygen saturation 97 percent on room air. She has no aspirin allergy and has not taken erectile-dysfunction drugs. After applying the cardiac monitor, which intervention should the AEMT prioritize first?
- Give sublingual nitroglycerin 0.4 mg immediately
- Apply high-flow oxygen by non-rebreather mask
- Start a large-bore IV and run a 500 mL fluid bolus
- Administer aspirin 324 mg chewable by mouth
Correct answer: Administer aspirin 324 mg chewable by mouth
Giving chewable aspirin 324 mg by mouth should come first. In suspected acute coronary syndrome, aspirin's antiplatelet effect reduces clot progression and improves survival, and the patient has no contraindication. High-flow oxygen is not indicated when saturation is already 97 percent because hyperoxia can worsen ischemia, and nitroglycerin, while appropriate, follows aspirin and requires confirming an adequate blood pressure first.
- An AEMT finds a 30-year-old man unresponsive with shallow breathing of about 6 per minute, pinpoint pupils, and a cyanotic appearance. Bystanders report he 'used something' an hour ago. After opening the airway, what is the most appropriate immediate action?
- Apply a non-rebreather mask at 15 L/min and monitor saturation
- Administer intranasal naloxone and wait to see if breathing improves before ventilating
- Begin assisted ventilations with a bag-valve mask and supplemental oxygen
- Place an oral airway and prepare for rapid transport without ventilating
Correct answer: Begin assisted ventilations with a bag-valve mask and supplemental oxygen
Beginning assisted ventilations with a bag-valve mask and supplemental oxygen is the immediate priority. The lethal problem in opioid overdose is hypoventilation and hypoxia, so correcting oxygenation comes before drug administration. Naloxone is given, but ventilating first prevents hypoxic arrest while the medication is prepared; a non-rebreather alone does nothing for a patient who is not moving adequate air.
- A diabetic patient is found confused, diaphoretic, and combative. A finger-stick reads 38 mg/dL. The patient is too altered to safely swallow and keeps spitting out anything placed in the mouth. After ensuring airway protection, which intervention best matches the AEMT scope and the patient's condition?
- Place oral glucose gel between the cheek and gum and reassess in 10 minutes
- Establish IV access and administer 12.5 to 25 grams of 50 percent dextrose
- Administer naloxone in case an opioid is contributing to the altered mental status
- Withhold all glucose until the patient becomes cooperative
Correct answer: Establish IV access and administer 12.5 to 25 grams of 50 percent dextrose
Establishing IV access and giving 12.5 to 25 grams of 50 percent dextrose is correct. A patient who cannot safely swallow must not receive oral glucose because of aspiration risk, and the AEMT scope includes IV dextrose for severe hypoglycemia. Withholding treatment leaves the brain glucose-starved, and naloxone does nothing for a documented glucose of 38 mg/dL.
- A conscious, alert 65-year-old diabetic feels shaky and weak; a glucometer reads 54 mg/dL. He is able to follow commands and has an intact gag reflex. Which action is most appropriate?
- Start an IV and push 50 percent dextrose for faster correction
- Administer oral glucose gel, approximately 15 grams, and reassess
- Give intramuscular glucagon 1 mg
- Withhold treatment because the reading is above 50 mg/dL
Correct answer: Administer oral glucose gel, approximately 15 grams, and reassess
Giving oral glucose, about 15 grams, is the appropriate choice for a conscious hypoglycemic patient who can protect his airway. Oral glucose is the least invasive effective treatment and is squarely within scope. IV dextrose and IM glucagon are reserved for patients who cannot swallow safely, and 54 mg/dL is symptomatic hypoglycemia that should be treated rather than ignored.
- An AEMT is dispatched for a 'sick person.' On arrival, a 70-year-old woman is slumped in a chair with right-sided facial droop, slurred speech, and weakness of the right arm that began suddenly. The most important historical detail the AEMT must obtain to guide stroke center care is:
- The patient's current list of vitamins and supplements
- The exact time the patient was last known to be well (normal)
- The brand of blood pressure medication she takes
- Whether the patient has a history of migraines
Correct answer: The exact time the patient was last known to be well (normal)
Establishing the exact time the patient was last known to be well is the priority. Eligibility for time-sensitive stroke therapies such as clot-busting drugs and clot retrieval depends on this window, so it directly drives hospital destination and treatment. Migraine history, supplements, and medication brands are far less important to the acute decision and should not delay transport.
- A 45-year-old man is having an apparent grand mal seizure that has continued for more than 5 minutes without stopping. He is cyanotic during the convulsion. While positioning and protecting him, what is the AEMT's most appropriate priority action?
- Manage the airway and provide oxygen, then arrange rapid transport for a patient in prolonged seizure
- Withhold oxygen until the seizure stops to avoid airway trauma
- Force a bite block between the teeth to protect the tongue
- Restrain the extremities firmly to stop the convulsive movements
Correct answer: Manage the airway and provide oxygen, then arrange rapid transport for a patient in prolonged seizure
Managing the airway, providing oxygen, and arranging rapid transport is correct because a seizure lasting longer than 5 minutes is status epilepticus, a true emergency. The AEMT cannot administer the anticonvulsant medications used to terminate the seizure, so airway support and rapid movement toward definitive care are the priorities. Forcing objects into the mouth and restraining limbs cause injury and do not stop the seizure.
- An AEMT performs a primary assessment on a trauma patient struck by a car. The patient has noisy, gurgling respirations and is not maintaining his own airway. Following the assessment sequence, what should be addressed first?
- Splint the obviously deformed lower leg
- Apply a cervical collar before touching the airway
- Obtain a full set of vital signs
- Suction the airway to clear secretions and reassess breathing
Correct answer: Suction the airway to clear secretions and reassess breathing
Suctioning the airway to clear the gurgling secretions is the first priority because airway always precedes breathing, circulation, and lower-priority care in the primary survey. A patent airway is meaningless if it is full of fluid the patient cannot clear. Spinal precautions are maintained manually during suctioning, but the collar, vital signs, and splinting all follow once the airway is open.
- A 6-year-old child is in respiratory distress with stridor, drooling, a high fever, and is sitting forward in a tripod position refusing to lie down. The AEMT suspects epiglottitis. What is the most appropriate management approach?
- Have the parent restrain the child for an IV start before transport
- Keep the child calm in a position of comfort, provide blow-by oxygen, and transport without agitating the airway
- Perform repeated direct visualization of the throat with a tongue blade
- Lay the child supine and insert an oral airway to secure the airway
Correct answer: Keep the child calm in a position of comfort, provide blow-by oxygen, and transport without agitating the airway
Keeping the child calm in a position of comfort with blow-by oxygen and transporting without agitating the airway is correct. With suspected epiglottitis, anything that upsets the child or manipulates the throat can trigger complete airway obstruction. Forcing the child supine, inspecting the throat, or holding the child down for an IV all risk converting partial obstruction into a fatal one.
- During transport, a patient who initially had a patent airway and clear speech becomes increasingly drowsy, with slower and shallower respirations. The AEMT had applied oxygen and was monitoring. This change most importantly signals the need to:
- Continue the current oxygen and recheck vitals at the next scheduled interval
- Increase the oxygen flow rate and take no other action
- Reassess the airway and breathing immediately and begin assisting ventilations as needed
- Document the change and notify the receiving hospital after arrival
Correct answer: Reassess the airway and breathing immediately and begin assisting ventilations as needed
Reassessing airway and breathing immediately and assisting ventilations as needed is the priority. A deteriorating mental status with declining respiratory effort is a cue that the patient is failing to ventilate, and the AEMT must act on that cue now, not at the next interval. Waiting, documenting only, or merely raising oxygen flow ignores that the problem is inadequate ventilation, not just oxygen delivery.
- An AEMT is treating a chest pain patient and has given one dose of sublingual nitroglycerin. Before giving a second dose 5 minutes later, the most important reassessment is:
- Recheck the pupils for size and reactivity
- Recheck the patient's temperature
- Recheck the blood pressure to confirm the systolic remains adequate
- Auscultate bowel sounds
Correct answer: Recheck the blood pressure to confirm the systolic remains adequate
Rechecking the blood pressure to confirm an adequate systolic before the next nitroglycerin dose is essential. Nitroglycerin is a vasodilator that can cause dangerous hypotension, so a systolic that has dropped too low contraindicates a repeat dose. Pupils, bowel sounds, and temperature have no bearing on the safety of repeat nitroglycerin.
- A patient is found pale, cool, and diaphoretic with a rapid weak radial pulse and a blood pressure of 84/60. He reports several days of black, tarry stools. The AEMT recognizes the shock state. The most appropriate intervention within scope is to:
- Sit the patient fully upright and withhold IV fluids
- Provide high-flow oxygen, keep the patient warm and supine, establish IV access, and transport rapidly
- Give nitroglycerin to improve circulation
- Administer oral glucose to support blood pressure
Correct answer: Provide high-flow oxygen, keep the patient warm and supine, establish IV access, and transport rapidly
Providing high-flow oxygen, keeping the patient warm and supine, establishing IV access, and transporting rapidly is the correct response to hypovolemic shock from a likely gastrointestinal bleed. These steps support perfusion and oxygen delivery while moving toward definitive care. Sitting the patient upright worsens cerebral perfusion, oral glucose is irrelevant, and nitroglycerin would dangerously lower an already low blood pressure.
- An AEMT assesses an unresponsive adult who is not breathing normally and has no pulse. A second rescuer is present and an AED is available. What is the correct immediate sequence?
- Establish IV access before beginning compressions
- Begin high-quality chest compressions immediately while the AED is readied and apply it as soon as possible
- Wait for the AED to fully analyze before starting any compressions
- Deliver two rescue breaths first, then start compressions
Correct answer: Begin high-quality chest compressions immediately while the AED is readied and apply it as soon as possible
Beginning high-quality chest compressions immediately while the AED is readied is correct, following current resuscitation guidance that emphasizes early, minimally interrupted compressions and rapid defibrillation. Delaying compressions for breaths, for AED analysis, or for IV access reduces the coronary and cerebral perfusion that compressions provide and lowers survival.
- A motorcyclist is found with an obvious open fracture of the femur that is bleeding briskly in a steady, dark, flowing pattern. The AEMT recognizes which type of bleeding and applies which first intervention?
- Capillary bleeding requiring only a bandage
- Venous bleeding controlled with direct pressure and a pressure dressing
- Venous bleeding best ignored until the splint is applied
- Arterial bleeding requiring immediate cricothyrotomy
Correct answer: Venous bleeding controlled with direct pressure and a pressure dressing
Steady, dark, flowing blood indicates venous bleeding, which is controlled with direct pressure and a pressure dressing. Direct pressure is the first and most effective step for most external hemorrhage. Cricothyrotomy is outside the AEMT scope and unrelated to a leg wound, capillary bleeding oozes rather than flows, and bleeding must never be deferred for splinting.
- An AEMT is caring for a near-drowning victim pulled from a lake. The patient is breathing but coughing, with crackles in the lungs and a saturation of 89 percent on room air. The patient initially seems fine but the AEMT is concerned about delayed deterioration. The best plan is to:
- Withhold oxygen unless the saturation falls below 80 percent
- Allow the patient to refuse transport since breathing has returned
- Encourage the patient to lie flat and rest at the scene
- Apply high-concentration oxygen, monitor closely, and transport even though the patient feels improved
Correct answer: Apply high-concentration oxygen, monitor closely, and transport even though the patient feels improved
Applying high-concentration oxygen, monitoring closely, and transporting despite apparent improvement is correct. Submersion victims can develop delayed pulmonary complications hours later, so the low saturation and crackles mandate oxygen and hospital evaluation. Permitting refusal, withholding oxygen, or letting the patient rest at the scene all ignore the risk of progressive respiratory failure.
- A patient with a history of asthma is in severe distress with one-word answers, accessory muscle use, and a saturation of 88 percent. The AEMT gives a nebulized bronchodilator with little improvement after the first treatment. The most appropriate next step within scope is to:
- Reassess, consider CPAP if the patient can tolerate it, and prepare to assist ventilations while continuing oxygen
- Lay the patient supine to reduce the work of breathing
- Administer intramuscular epinephrine 0.3 mg for the asthma as the first-line drug
- Withhold further treatment and observe for spontaneous improvement
Correct answer: Reassess, consider CPAP if the patient can tolerate it, and prepare to assist ventilations while continuing oxygen
Reassessing, considering CPAP if tolerated, and preparing to assist ventilations while continuing oxygen is the appropriate escalation for severe asthma not responding to a bronchodilator. The AEMT continues supporting oxygenation and ventilation. Epinephrine is not the routine first-line asthma drug at this level, withholding care abandons a deteriorating patient, and lying a distressed patient flat increases work of breathing.
- An AEMT responds to a 'fall.' An 80-year-old on a blood thinner struck her head but has normal vital signs and is alert with no obvious deficits. The patient wishes to stay home. The AEMT's clinical judgment should be that:
- Only loss of consciousness at the time of injury would justify transport
- A normal exam means no further evaluation is needed and refusal is reasonable
- Vital signs are the sole reliable indicator of intracranial injury
- Anticoagulant use plus head trauma carries high risk of delayed intracranial bleeding, so transport should be strongly encouraged
Correct answer: Anticoagulant use plus head trauma carries high risk of delayed intracranial bleeding, so transport should be strongly encouraged
Recognizing that anticoagulant use combined with head trauma carries a high risk of delayed intracranial bleeding, and strongly encouraging transport, reflects sound clinical judgment. Blood thinners can let a slow bleed expand over hours after a normal initial exam. A reassuring exam, the absence of loss of consciousness, and normal vital signs do not rule out a developing bleed.
- A patient complains of sudden, severe, tearing chest pain radiating to the back. The AEMT notes a marked difference in blood pressure between the two arms. The most appropriate judgment and action is to:
- Delay transport to obtain repeated arm pressures every minute
- Assume the arm pressure difference is an equipment error and ignore it
- Suspect a possible aortic catastrophe, avoid giving nitroglycerin reflexively, support the patient, and transport rapidly
- Treat exactly as a standard heart attack and push to give three nitroglycerin doses
Correct answer: Suspect a possible aortic catastrophe, avoid giving nitroglycerin reflexively, support the patient, and transport rapidly
Suspecting a possible aortic catastrophe, avoiding reflexive nitroglycerin, supporting the patient, and transporting rapidly is the best judgment. Tearing pain to the back with a blood pressure difference between arms suggests aortic dissection, which is managed very differently from a typical heart attack. Treating it as routine cardiac pain, dismissing the finding as error, or delaying transport for repeated readings all endanger the patient.
- An AEMT arrives at a scene where a worker collapsed in a confined grain bin. Another worker is preparing to climb in to help. The AEMT's first priority is to:
- Immediately climb in to assess the downed worker's airway
- Hand the bystander a bag-valve mask to begin ventilating the patient
- Prevent rescuer entry and ensure scene safety before any patient contact
- Start documenting the mechanism of injury
Correct answer: Prevent rescuer entry and ensure scene safety before any patient contact
Preventing rescuer entry and ensuring scene safety before any patient contact is the priority. Confined spaces may contain toxic or oxygen-deficient atmospheres that incapacitate untrained rescuers, turning one victim into several. Rushing in, sending a bystander in, or documenting first all ignore the rule that no patient can be helped if the rescuers become victims.
- A 2-month-old infant is limp, pale, and not feeding, with cool extremities and prolonged capillary refill. The parents say the baby has been vomiting and having diarrhea for two days. The AEMT recognizes this presentation as most consistent with:
- Compensated to decompensating shock from dehydration requiring oxygen, warmth, and rapid transport
- A normal sleepy infant needing only reassurance
- A behavioral feeding problem managed by feeding advice
- Simple constipation requiring no intervention
Correct answer: Compensated to decompensating shock from dehydration requiring oxygen, warmth, and rapid transport
Recognizing shock from dehydration, and providing oxygen, warmth, and rapid transport, is the correct judgment. A limp, pale infant with poor perfusion after days of fluid loss is critically ill, and infants decompensate suddenly. Dismissing the baby as sleepy, treating it as a feeding behavior, or attributing it to constipation overlooks life-threatening hypoperfusion.
- An AEMT is treating a patient with chest pain and discovers the patient took a phosphodiesterase inhibitor (an erectile-dysfunction drug) earlier that day. The clinically correct decision is to:
- Administer two doses of nitroglycerin rapidly to overcome any interaction
- Withhold nitroglycerin because of the risk of profound, dangerous hypotension
- Give nitroglycerin only if the systolic pressure exceeds 160
- Give nitroglycerin but reduce the dose by half
Correct answer: Withhold nitroglycerin because of the risk of profound, dangerous hypotension
Withholding nitroglycerin is correct because combining it with a phosphodiesterase inhibitor can cause severe, refractory hypotension. This is an absolute contraindication regardless of how high the blood pressure currently is. Halving the dose, using a pressure threshold, or giving more does not make the combination safe.
- A young woman is found unresponsive at a party. She breathes adequately, has a pulse, and a finger-stick glucose is normal. The AEMT cannot determine a cause. Following good clinical judgment for the unresponsive patient of unknown cause, the AEMT should:
- Administer dextrose despite the normal glucose reading
- Withhold transport until she wakes up on her own
- Maintain the airway, place her in the recovery position if no trauma is suspected, monitor, and transport for evaluation
- Assume intoxication, leave her with friends, and clear the scene
Correct answer: Maintain the airway, place her in the recovery position if no trauma is suspected, monitor, and transport for evaluation
Maintaining the airway, using the recovery position if there is no trauma, monitoring, and transporting is correct. An unresponsive patient of unknown cause needs airway protection and hospital evaluation because many serious conditions present this way. Assuming intoxication, giving unneeded dextrose, or waiting for spontaneous waking all risk missing a treatable emergency.
- An AEMT places a supraglottic airway in an apneic patient. After insertion, ventilation meets strong resistance, the chest does not rise, and waveform capnography shows no carbon dioxide. The most appropriate immediate action is to:
- Assume the capnography is malfunctioning and proceed
- Remove the device, ventilate with a bag-valve mask, and reattempt or use an alternative airway
- Leave the device in place and begin transport without ventilating
- Continue forceful ventilation through the device and increase the pressure
Correct answer: Remove the device, ventilate with a bag-valve mask, and reattempt or use an alternative airway
Removing the device, ventilating with a bag-valve mask, and reattempting or using an alternative airway is correct. No chest rise plus absent capnography means the airway is not functioning, so the AEMT must restore a working method of ventilation. Forcing air, blaming the monitor, or transporting without ventilating leaves the patient without effective oxygenation.
- A patient struck in the chest by a steering wheel is increasingly short of breath. The AEMT notes absent breath sounds on one side, distended neck veins, and a falling blood pressure. The AEMT recognizes this life threat as:
- Hyperventilation syndrome treated by breathing into a bag
- Simple anxiety requiring reassurance
- Acute coronary syndrome requiring nitroglycerin
- Tension pneumothorax requiring rapid transport and ventilatory support, with paramedic intercept if available
Correct answer: Tension pneumothorax requiring rapid transport and ventilatory support, with paramedic intercept if available
Recognizing tension pneumothorax and arranging rapid transport with ventilatory support, plus paramedic intercept if available, is the correct judgment. Absent unilateral breath sounds, distended neck veins, and falling blood pressure after chest trauma indicate rising intrathoracic pressure that the AEMT cannot definitively decompress. Calling it anxiety, hyperventilation, or coronary disease misses a rapidly fatal mechanical problem.
- An AEMT is dispatched to a residential carbon monoxide alarm activation. A family of four reports headache, nausea, and dizziness. The pulse oximeter reads 98 percent on all of them. The correct interpretation is that:
- A normal pulse oximetry reading rules out significant exposure
- Oxygen should be withheld to avoid masking the symptoms
- Standard pulse oximetry can read falsely normal in carbon monoxide poisoning, so high-flow oxygen and transport are still indicated
- Only the most symptomatic family member needs treatment
Correct answer: Standard pulse oximetry can read falsely normal in carbon monoxide poisoning, so high-flow oxygen and transport are still indicated
Understanding that standard pulse oximetry can read falsely normal in carbon monoxide poisoning, and still applying high-flow oxygen and transporting, is correct. Carbon monoxide binds hemoglobin and fools the device, so symptoms outweigh a reassuring number. Trusting the saturation, treating only one person, or withholding oxygen all endanger exposed patients.
- A trauma patient is being assessed. The AEMT must decide whether the situation is a 'load and go' or allows time for more on-scene care. The single most important factor driving this decision is:
- Whether the patient prefers a particular hospital
- The presence of life threats found in the primary assessment and the patient's physiologic stability
- The distance to the nearest urgent care clinic
- The patient's insurance status
Correct answer: The presence of life threats found in the primary assessment and the patient's physiologic stability
The presence of life threats in the primary assessment and the patient's physiologic stability is the key factor. A patient with airway, breathing, or circulation compromise needs rapid transport to definitive surgical care, while a stable patient permits more thorough on-scene assessment. Insurance, clinic distance, and hospital preference do not determine the urgency of moving a critical trauma patient.
- An AEMT responds to a worker who spilled a strong acid on the forearm. The skin is reddened and painful and the patient is otherwise stable. After ensuring scene safety and personal protection, the priority intervention is to:
- Apply ice directly to the burn to reduce pain
- Brush off any dry chemical, then irrigate the area with copious water for a prolonged period
- Apply a chemical-neutralizing agent to counteract the acid
- Cover the burn with a dry dressing and transport without irrigation
Correct answer: Brush off any dry chemical, then irrigate the area with copious water for a prolonged period
Brushing off dry chemical and then irrigating with copious water for a prolonged period is the correct treatment for a chemical burn. Continuous flushing dilutes and removes the agent and limits tissue damage. Neutralizing agents can generate heat and worsen injury, a dry dressing leaves the chemical in contact with skin, and ice can cause additional tissue damage.
- A 70-year-old man presents with new confusion, fever, rapid heart rate, warm flushed skin, and a blood pressure of 88/50. He recently had a urinary infection. The AEMT's clinical judgment should identify this as:
- A simple urinary tract infection needing no urgent care
- Septic (distributive) shock requiring oxygen, IV access with fluid support per protocol, and rapid transport
- A panic attack requiring reassurance
- Heat exhaustion treated only by cooling
Correct answer: Septic (distributive) shock requiring oxygen, IV access with fluid support per protocol, and rapid transport
Identifying septic, distributive shock and providing oxygen, IV fluid support per protocol, and rapid transport is the correct judgment. Fever, confusion, tachycardia, warm skin, and hypotension after an infection point to sepsis, a time-critical emergency. Calling it a simple infection, heat exhaustion, or a panic attack delays the fluids and hospital care these patients need.
- An AEMT obtains a blood pressure of 250/130 in a patient complaining of a severe headache and blurred vision. The patient is alert and oriented. The most appropriate action within scope is to:
- Recognize a hypertensive emergency, keep the patient calm, monitor, and transport without attempting to lower the pressure with field medications
- Withhold transport and recheck the pressure in 30 minutes
- Administer nitroglycerin to rapidly bring down the blood pressure
- Have the patient lie flat and elevate the legs to redistribute the pressure
Correct answer: Recognize a hypertensive emergency, keep the patient calm, monitor, and transport without attempting to lower the pressure with field medications
Recognizing a hypertensive emergency, keeping the patient calm, monitoring, and transporting without trying to lower the pressure with field drugs is correct. AEMTs do not carry agents to safely titrate blood pressure, and abrupt drops can harm the brain. Giving nitroglycerin off-protocol, repositioning to alter pressure, or delaying transport are all inappropriate.
- An AEMT is treating a multisystem trauma patient and has only enough time for limited interventions before transport. Which intervention should take precedence?
- Applying a traction splint to a closed femur deformity
- Bandaging minor abrasions
- Controlling severe external hemorrhage and maintaining the airway
- Obtaining a complete past medical history
Correct answer: Controlling severe external hemorrhage and maintaining the airway
Controlling severe external hemorrhage and maintaining the airway take precedence because they address immediate threats to life. Uncontrolled bleeding and airway loss kill within minutes. A traction splint, minor abrasion care, and a complete history are lower priorities that should not delay transport of a critical patient.
- A patient who received intramuscular epinephrine for anaphylaxis is improving but the AEMT must continue monitoring during transport. The most important reason to keep monitoring closely is that:
- Anaphylaxis never recurs once epinephrine is given
- Epinephrine causes prolonged sedation that must be watched
- Symptoms can recur (biphasic reaction) and the airway may worsen again after initial improvement
- The patient will become hypoglycemic from the epinephrine
Correct answer: Symptoms can recur (biphasic reaction) and the airway may worsen again after initial improvement
The key reason for continued close monitoring is that anaphylaxis symptoms can recur as a biphasic reaction, and the airway can worsen again after initial improvement. The AEMT must be ready to support the airway and repeat treatment per protocol. Epinephrine does not cause sedation, and the statement that anaphylaxis never recurs is false, which is exactly why monitoring continues.
- An AEMT finds a patient who fell from a roof, lying still and complaining of neck pain with tingling in both hands. The patient is breathing adequately. The most appropriate handling decision is to:
- Have the patient walk to the stretcher to save time
- Apply a collar and then allow the patient to move freely
- Sit the patient fully upright for transport comfort
- Maintain manual in-line spinal stabilization and use careful movement techniques while assessing and transporting
Correct answer: Maintain manual in-line spinal stabilization and use careful movement techniques while assessing and transporting
Maintaining manual in-line spinal stabilization with careful movement during assessment and transport is correct. A fall from height with neck pain and bilateral extremity tingling suggests possible spinal cord involvement, so motion must be minimized. Letting the patient walk, allowing free movement after a collar, or sitting the patient upright all risk worsening a spinal injury.
- A patient on dialysis missed two sessions and now presents weak with a slow, irregular pulse. The AEMT cannot definitively diagnose the rhythm but recognizes a potential life threat. The best judgment is to:
- Encourage oral fluids to correct the problem at the scene
- Assume the slow pulse is normal for dialysis patients and downgrade urgency
- Withhold the cardiac monitor since AEMTs cannot interpret rhythms
- Suspect a possible electrolyte (potassium) disturbance, provide oxygen and monitoring, establish IV access, and transport rapidly
Correct answer: Suspect a possible electrolyte (potassium) disturbance, provide oxygen and monitoring, establish IV access, and transport rapidly
Suspecting an electrolyte disturbance such as elevated potassium, providing oxygen and monitoring, establishing IV access, and transporting rapidly is the correct judgment. Missed dialysis commonly causes dangerous potassium buildup that affects the heart. Dismissing the slow pulse, giving oral fluids, or skipping the monitor all overlook a potentially lethal and reversible cause.
- An AEMT is ventilating an apneic adult with a bag-valve mask. The chest rises with each squeeze, but it is difficult to maintain a seal alone. The best solution to improve ventilation quality is to:
- Switch to mouth-to-mask without supplemental oxygen
- Reduce the oxygen flow to lower the mask pressure
- Squeeze the bag faster and harder to force air past the leak
- Use a two-person bag-valve-mask technique with one rescuer sealing the mask and the other squeezing the bag
Correct answer: Use a two-person bag-valve-mask technique with one rescuer sealing the mask and the other squeezing the bag
Using a two-person bag-valve-mask technique is the best solution because one rescuer can achieve a better mask seal with both hands while the second delivers measured breaths. Squeezing faster and harder risks gastric inflation and barotrauma, mouth-to-mask without oxygen lowers the delivered oxygen concentration, and reducing oxygen flow does not fix a seal problem.
- A patient with severe abdominal pain and a rigid, board-like abdomen lies very still and resists any movement. Vital signs show early tachycardia. The AEMT's clinical judgment should be to:
- Assume it is indigestion and recommend antacids at home
- Encourage the patient to eat and drink to settle the stomach
- Treat this as a possible surgical abdomen, withhold oral intake, provide comfort positioning, and transport for evaluation
- Apply firm, deep palpation repeatedly to localize the pain
Correct answer: Treat this as a possible surgical abdomen, withhold oral intake, provide comfort positioning, and transport for evaluation
Treating a rigid, board-like abdomen as a possible surgical emergency, withholding oral intake, positioning for comfort, and transporting is correct. Rigidity and guarding suggest peritoneal irritation that may require surgery, so nothing should be given by mouth. Encouraging food, repeated deep palpation, or dismissing it as indigestion can worsen the condition or delay critical care.
- An AEMT arrives to find a patient with an altered mental status, hot dry skin, and a body temperature that feels markedly elevated after prolonged outdoor activity in extreme heat. The most appropriate immediate intervention is to:
- Withhold cooling until the temperature is confirmed with a thermometer
- Begin rapid active cooling, move the patient to a cool environment, support the airway, and transport rapidly
- Wrap the patient in blankets to prevent shivering
- Give oral fluids despite the altered mental status
Correct answer: Begin rapid active cooling, move the patient to a cool environment, support the airway, and transport rapidly
Beginning rapid active cooling, moving to a cool environment, supporting the airway, and transporting rapidly is correct for heat stroke. Altered mental status with hot skin in extreme heat is a life threat where minutes of delay increase mortality. Wrapping in blankets traps heat, oral fluids risk aspiration in an altered patient, and waiting to cool wastes critical time.
- An AEMT must decide the destination for a critically injured trauma patient. The closest hospital is a small community emergency department; a Level I trauma center is 20 minutes farther. The most appropriate judgment is to:
- Transport to the trauma center capable of definitive surgical care when the patient meets trauma criteria, considering air medical resources if appropriate
- Let the patient choose based on familiarity
- Always transport to the closest facility regardless of injuries
- Transport to whichever hospital has the shortest wait time
Correct answer: Transport to the trauma center capable of definitive surgical care when the patient meets trauma criteria, considering air medical resources if appropriate
Transporting to the trauma center capable of definitive surgical care when the patient meets trauma criteria, and considering air medical transport if appropriate, reflects sound destination judgment. Critically injured patients have better outcomes at trauma centers even if slightly farther. Defaulting to the closest facility, patient familiarity, or wait times can deny a critical patient the specialized care they need.
- A patient with known congestive heart failure is sitting bolt upright, gasping, with pink frothy sputum and crackles throughout both lungs. Saturation is 84 percent. After high-flow oxygen, the most appropriate intervention within scope is to:
- Apply CPAP if there are no contraindications and the patient can tolerate it, while preparing to assist ventilations
- Administer a large IV fluid bolus to support the blood pressure
- Encourage the patient to take slow deep breaths and reassess in 15 minutes
- Lay the patient flat to make ventilation easier
Correct answer: Apply CPAP if there are no contraindications and the patient can tolerate it, while preparing to assist ventilations
Applying CPAP if there are no contraindications and the patient tolerates it, while preparing to assist ventilations, is the correct intervention for acute pulmonary edema. CPAP improves oxygenation and reduces the work of breathing. Lying the patient flat worsens breathing, a fluid bolus floods already congested lungs, and passive reassurance wastes time in a deteriorating patient.
- During patient assessment, the AEMT notes the patient answers questions appropriately but cannot recall the day or where they are, a change from baseline reported by family. This finding is best classified and acted on as:
- An indication to immediately restrain the patient
- A normal variant that requires no further concern
- Evidence the patient is uncooperative and can be cleared
- A new alteration in mental status that itself is a significant cue requiring investigation of an underlying cause
Correct answer: A new alteration in mental status that itself is a significant cue requiring investigation of an underlying cause
Classifying the disorientation as a new alteration in mental status, and treating it as a significant cue to investigate an underlying cause, is correct clinical judgment. A change from baseline can signal hypoglycemia, stroke, hypoxia, infection, or other emergencies. Dismissing it as normal, labeling the patient uncooperative, or jumping to restraint all ignore a potentially serious problem.
- An AEMT is at the scene of a vehicle collision with three patients and only one ambulance immediately available. One patient is apneic with no pulse after repositioning the airway, one has an open femur fracture with controlled bleeding and is alert, and one is walking around complaining of neck pain. Using standard mass-casualty triage logic, the AEMT should:
- Transport the walking patient first because they are most cooperative
- Tag the apneic pulseless patient as expectant under these conditions and direct immediate resources to the salvageable critically injured patient
- Devote all resources to attempting full resuscitation of the apneic pulseless patient
- Treat all three simultaneously with the single available crew
Correct answer: Tag the apneic pulseless patient as expectant under these conditions and direct immediate resources to the salvageable critically injured patient
Under mass-casualty triage logic, tagging the apneic pulseless patient as expectant when resources are scarce and directing care to the salvageable critically injured patient is correct. Triage maximizes survival across all patients rather than expending limited resources on the least salvageable. Committing everything to the pulseless patient, prioritizing the ambulatory patient, or trying to treat everyone at once mismanages scarce resources.
- A patient suspected of a stroke is identified, and the AEMT confirms a clear time of last known well within a treatable window. Beyond rapid transport, the most valuable thing the AEMT can do to support definitive care is to:
- Pre-notify the receiving stroke center so the stroke team can be ready on arrival
- Stop to obtain a 12-lead and full laboratory workup in the field
- Administer aspirin to treat the suspected clot
- Lower the patient's blood pressure with field medication
Correct answer: Pre-notify the receiving stroke center so the stroke team can be ready on arrival
Pre-notifying the receiving stroke center so the team is ready on arrival is the most valuable supporting action. Early notification shortens the time to imaging and treatment, which directly affects outcomes. Field labs are unavailable and would delay transport, aspirin is contraindicated until a bleed is excluded by imaging, and AEMTs do not lower blood pressure in stroke.
- An AEMT is reassessing a patient who was treated for hypoglycemia with IV dextrose and is now awake and answering questions appropriately. The patient insists on refusing transport. The best clinical and judgment-based response is to:
- Recheck the glucose, evaluate for an underlying cause, advise on the risk of recurrence, and document an informed refusal if the patient remains decisional
- Immediately clear the scene since the patient is now alert
- Administer a second dose of dextrose to prevent any future drop
- Force the patient onto the stretcher for transport against their will
Correct answer: Recheck the glucose, evaluate for an underlying cause, advise on the risk of recurrence, and document an informed refusal if the patient remains decisional
Rechecking the glucose, evaluating for an underlying cause, advising on the risk of recurrence, and documenting an informed refusal if the patient remains decisional is the correct, judgment-driven response. Hypoglycemia can recur, especially with long-acting oral diabetes drugs, so the patient must understand the risk. Simply clearing the scene, forcing transport, or giving more dextrose to a normoglycemic patient are all inappropriate.
- A patient presents with sudden one-sided weakness and slurred speech, but symptoms completely resolve before EMS arrival, and the patient now appears normal. The AEMT's appropriate judgment is to:
- Treat the patient as a routine fatigue complaint
- Recognize a possible transient ischemic attack as a warning of imminent stroke and strongly encourage transport and evaluation
- Conclude that resolved symptoms mean no emergency and release the patient
- Wait at the scene to see whether the symptoms return before deciding
Correct answer: Recognize a possible transient ischemic attack as a warning of imminent stroke and strongly encourage transport and evaluation
Recognizing a possible transient ischemic attack as a warning sign of an imminent stroke and strongly encouraging transport and evaluation is correct. A TIA carries a high short-term risk of a completed stroke, so resolved symptoms still demand urgent assessment. Releasing the patient, treating it as fatigue, or waiting for recurrence all miss the opportunity to prevent a disabling stroke.
- An AEMT is caring for an injured patient who is calm initially but becomes increasingly restless, anxious, and is asking repeatedly for water, with a rising pulse and narrowing pulse pressure. These changing cues most likely indicate:
- Early (compensated) shock that warrants aggressive intervention and rapid transport before blood pressure falls
- Normal anxiety from being in an ambulance
- Simple dehydration that can wait for hospital fluids
- An allergic reaction to a bandage
Correct answer: Early (compensated) shock that warrants aggressive intervention and rapid transport before blood pressure falls
Interpreting restlessness, anxiety, thirst, rising pulse, and narrowing pulse pressure as early compensated shock, and intervening aggressively with rapid transport before blood pressure falls, is correct. These are the body's compensatory cues that precede a drop in blood pressure, which is a late finding. Dismissing them as anxiety, ordinary dehydration, or a bandage allergy delays treatment until decompensation occurs.
- An AEMT must select the most appropriate way to confirm and monitor effective ventilation in an apneic patient managed with a bag-valve mask and supraglottic airway. The best tool to continuously confirm ongoing ventilation is:
- Counting the rescuer's squeezes per minute only
- A single pulse oximetry reading taken once
- Skin color assessed by visual inspection alone
- Waveform capnography measuring exhaled carbon dioxide
Correct answer: Waveform capnography measuring exhaled carbon dioxide
Waveform capnography measuring exhaled carbon dioxide is the best tool to continuously confirm ongoing ventilation and detect problems such as airway dislodgement in real time. A single pulse oximetry reading lags behind ventilation changes, skin color is unreliable and late, and counting squeezes confirms effort but not actual gas exchange.
- An AEMT responds for a marathon runner who collapsed on a hot, humid day. The patient is confused, has hot dry skin, a core temperature that feels very high, and a rapid weak pulse. Recognizing these cues together, what is the most appropriate immediate action within the AEMT scope?
- Wrap the patient in blankets to prevent further heat loss
- Begin rapid active cooling, support the airway, and transport rapidly while treating this as heat stroke
- Wait for the temperature to be measured at the hospital before cooling
- Encourage the patient to drink several glasses of cold water
Correct answer: Begin rapid active cooling, support the airway, and transport rapidly while treating this as heat stroke
Beginning rapid active cooling, supporting the airway, and transporting rapidly is correct because hot skin with altered mental status signals heat stroke, a true emergency where cooling cannot wait. Wrapping the patient in blankets traps heat, oral fluids are unsafe in a confused patient, and delaying cooling until the hospital allows brain injury to progress.
- An AEMT finds an elderly patient who fell outdoors in winter and was found hours later. The patient is drowsy, shivering has stopped, the skin is cold, and the heart rate and breathing are slow. What does sound clinical judgment direct the AEMT to do during movement and transport?
- Apply direct high heat to the extremities first
- Have the patient stand and walk to the ambulance to warm up
- Handle the patient gently, remove wet clothing, insulate to prevent further heat loss, and transport, because rough handling can trigger dangerous rhythms
- Vigorously rub the limbs to generate warmth quickly
Correct answer: Handle the patient gently, remove wet clothing, insulate to prevent further heat loss, and transport, because rough handling can trigger dangerous rhythms
Handling the patient gently, removing wet clothing, insulating, and transporting is correct because severe hypothermia makes the heart irritable, and rough handling or jostling can provoke fatal arrhythmias. Vigorous rubbing, walking the patient, or heating the extremities first can drive cold blood to the core and worsen the situation.
- An AEMT assesses a 70-year-old diabetic woman with fatigue, nausea, and shortness of breath but no chest pain. She is pale and diaphoretic with an irregular pulse. What clinical-judgment concern should most shape the AEMT's plan?
- Assume anxiety because the patient denies chest pain
- Attribute the symptoms entirely to the flu and recommend rest
- Reassure the patient that without chest pain a cardiac cause is ruled out
- Treat this as a possible atypical heart attack, since older adults and diabetics often present without classic chest pain
Correct answer: Treat this as a possible atypical heart attack, since older adults and diabetics often present without classic chest pain
Treating this as a possible atypical heart attack is correct because older adults, women, and diabetics frequently have myocardial infarctions without classic chest pain, presenting instead with weakness, nausea, dyspnea, and diaphoresis. Ruling out a cardiac cause based on the absence of chest pain, or blaming the flu or anxiety, risks missing a life threat.
- An AEMT is called for a patient with a severe nosebleed that has continued for 20 minutes. The patient is alert and the airway is clear. What is the most appropriate first intervention?
- Have the patient sit up, lean slightly forward, and pinch the soft part of the nose firmly and continuously
- Tell the patient to blow the nose hard to clear the clots
- Pack the nose tightly with a large object and lay the patient flat
- Tilt the patient's head back so the blood can drain
Correct answer: Have the patient sit up, lean slightly forward, and pinch the soft part of the nose firmly and continuously
Having the patient sit up, lean forward, and pinch the soft part of the nose is correct because forward positioning prevents blood from draining into the airway and direct pressure controls most anterior nosebleeds. Tilting the head back lets blood enter the throat and stomach, lying flat risks aspiration, and blowing the nose dislodges forming clots.
- An AEMT responds to a worker with an abdominal wound from which a loop of bowel is protruding. The patient is alert with stable vital signs. What is the correct management of the exposed organ?
- Cover the eviscerated organ with a moist sterile dressing and then an occlusive covering, and do not push it back in
- Pour antiseptic solution directly onto the exposed bowel
- Push the organ gently back into the abdomen and tape the wound closed
- Apply a dry gauze dressing directly and leave the organ exposed to air
Correct answer: Cover the eviscerated organ with a moist sterile dressing and then an occlusive covering, and do not push it back in
Covering the eviscerated organ with a moist sterile dressing and an occlusive covering is correct because keeping the tissue moist prevents drying and damage while protecting it from contamination. Pushing the organ back risks infection and further injury, a dry dressing causes the tissue to adhere and dry out, and antiseptic poured on exposed bowel is harmful.
- An AEMT finds a patient with a knife impaled in the thigh. The patient is alert with controlled bleeding around the object. What is the most appropriate action?
- Push the knife in deeper to stop it from moving during transport
- Cut the visible portion of the blade off to make transport easier
- Stabilize the impaled object in place with bulky dressings and transport without removing it
- Remove the knife quickly to allow better wound packing
Correct answer: Stabilize the impaled object in place with bulky dressings and transport without removing it
Stabilizing the impaled object in place with bulky dressings and transporting is correct because removing it may dislodge a clot or lacerate a vessel, causing severe bleeding. Removing the knife, pushing it deeper, or cutting the blade all risk worsening internal injury and uncontrolled hemorrhage; the object is removed in a controlled setting.
- An AEMT is treating an agitated, combative patient who poses a danger to self and the crew, and a restraint decision must be made. What clinical-judgment principle should guide the use of restraints?
- Restrain the patient and then stop assessing vital signs to avoid agitation
- Place the patient face-down and secure all four limbs as tightly as possible
- Avoid restraint entirely even when the patient is harming the crew
- Use the least restrictive means necessary, never restrain a patient prone, and monitor airway, breathing, and circulation continuously after restraint
Correct answer: Use the least restrictive means necessary, never restrain a patient prone, and monitor airway, breathing, and circulation continuously after restraint
Using the least restrictive means necessary, never restraining prone, and monitoring airway, breathing, and circulation is correct because prone restraint risks positional asphyxia and a restrained patient still needs continuous assessment for deterioration. Tight four-point prone restraint, stopping monitoring, or refusing to restrain a dangerous patient all create serious safety risks.
- An AEMT assesses an adult with burns to the entire front of the torso and the entire front of one arm after a house fire. Using the rule of nines for an adult, what is the approximate total body surface area burned?
- About 9 percent
- About 22.5 percent
- About 36 percent
- About 50 percent
Correct answer: About 22.5 percent
About 22.5 percent is correct because the anterior trunk is roughly 18 percent and the anterior surface of one arm is about 4.5 percent, which together total approximately 22.5 percent using the adult rule of nines. The other estimates do not match the standard surface-area assignments for these regions, which guides fluid and triage decisions.
- An AEMT responds to a house where two occupants complain of headache, nausea, and dizziness, and a third is unresponsive. A furnace has been running and a detector is alarming. What should most shape the AEMT's immediate action?
- Assume food poisoning and treat only the unresponsive patient
- Begin a detailed neurologic exam inside the home before moving anyone
- Rely on the pulse oximeter reading to rule out the exposure
- Recognize possible carbon monoxide exposure, move everyone to fresh air, apply high-concentration oxygen, and ensure crew safety
Correct answer: Recognize possible carbon monoxide exposure, move everyone to fresh air, apply high-concentration oxygen, and ensure crew safety
Recognizing possible carbon monoxide exposure, moving everyone to fresh air, applying high-concentration oxygen, and ensuring crew safety is correct because multiple people with similar symptoms in one location with a combustion source suggests CO poisoning. A standard pulse oximeter can read falsely normal in CO poisoning, so it cannot rule it out, and staying inside endangers patients and crew.
- An AEMT is treating a patient with a venomous snakebite to the forearm. The bite area is swelling and the patient is anxious. What is the most appropriate field management?
- Cut the bite open and attempt to suck out the venom
- Apply a tight tourniquet above the bite to stop venom spread
- Keep the patient calm and still, immobilize the limb at or below heart level, remove rings and tight items, and transport
- Apply ice directly to the bite and elevate the limb high above the heart
Correct answer: Keep the patient calm and still, immobilize the limb at or below heart level, remove rings and tight items, and transport
Keeping the patient calm and still, immobilizing the limb at or below heart level, removing constricting items, and transporting is correct because reducing movement slows venom spread and removing jewelry prepares for swelling. A tourniquet, cutting and suction, and ice are outdated and harmful practices that increase tissue damage.
- An AEMT assesses a 2-year-old with a barking, seal-like cough, mild stridor when upset, a low fever, and no drooling. The child is alert and consolable. What does this presentation most likely represent, and how should it shape care?
- A complete airway obstruction requiring abdominal thrusts
- Epiglottitis, so the AEMT should immediately examine the throat with a tongue blade
- Croup, so the AEMT should keep the child calm, provide humidified or blow-by oxygen as needed, and transport without agitating the child
- A simple cold that needs no monitoring or transport
Correct answer: Croup, so the AEMT should keep the child calm, provide humidified or blow-by oxygen as needed, and transport without agitating the child
Croup is the likely cause, so the AEMT should keep the child calm, provide humidified or blow-by oxygen as needed, and transport without agitating the child. A barking cough with low fever and no drooling fits croup. Examining the throat is dangerous in suspected epiglottitis, abdominal thrusts are for choking, and dismissing it as a cold ignores potential airway compromise.
- An AEMT is dispatched for a feverish, ill-appearing child who is sitting upright, drooling, leaning forward in a tripod position, and refusing to lie down, with muffled voice and high fever. What is the most appropriate clinical-judgment action?
- Keep the child in a position of comfort, avoid agitating or examining the throat, provide blow-by oxygen, and transport urgently for possible epiglottitis
- Tell the parents this is a minor sore throat and delay transport
- Force the child to lie flat for a thorough airway exam
- Insert an oral airway to keep the airway open
Correct answer: Keep the child in a position of comfort, avoid agitating or examining the throat, provide blow-by oxygen, and transport urgently for possible epiglottitis
Keeping the child in a position of comfort, avoiding agitation and throat examination, providing blow-by oxygen, and transporting urgently is correct because the tripod position, drooling, and muffled voice suggest epiglottitis, where any agitation can cause complete airway obstruction. Forcing the child flat, inserting an airway, or dismissing the complaint can precipitate a fatal airway closure.
- An AEMT is treating a patient on dialysis who missed a session and now has weakness, nausea, and a slow, irregular heartbeat. What underlying problem should most concern the AEMT and shape rapid transport?
- Possible high potassium levels causing dangerous heart rhythm changes
- Low blood sugar requiring oral glucose
- Dehydration requiring a large rapid fluid bolus
- A simple anxiety reaction to missing dialysis
Correct answer: Possible high potassium levels causing dangerous heart rhythm changes
Possible high potassium levels causing dangerous heart rhythm changes is correct because missed dialysis allows potassium to accumulate, which can cause lethal arrhythmias and cardiac arrest. Anxiety and low blood sugar do not explain a slow irregular rhythm in this context, and a large rapid bolus could worsen fluid overload in a dialysis patient.
- An AEMT cares for a patient vomiting large amounts of bright red blood with a history of alcohol use. The patient is pale, has a rapid pulse, and a falling blood pressure. What is the most appropriate AEMT priority?
- Place the patient flat on the back regardless of active vomiting
- Have the patient drink milk to coat the stomach
- Protect the airway from aspiration, provide oxygen, establish IV access for fluids per protocol, and transport rapidly for the gastrointestinal bleed
- Withhold fluids because the bleeding is in the stomach
Correct answer: Protect the airway from aspiration, provide oxygen, establish IV access for fluids per protocol, and transport rapidly for the gastrointestinal bleed
Protecting the airway from aspiration, providing oxygen, establishing IV access for fluids per protocol, and transporting rapidly is correct because massive upper gastrointestinal bleeding causes both aspiration risk and hemorrhagic shock. Giving oral fluids, withholding IV fluids in shock, or laying an actively vomiting patient supine all endanger the airway and perfusion.
- An AEMT assesses a 65-year-old man with sudden severe abdominal and back pain who is pale and sweaty with a pulsating mass in the abdomen and a falling blood pressure. What does sound clinical judgment most suggest?
- Indigestion that will resolve on its own
- A possible leaking or ruptured abdominal aortic aneurysm requiring gentle handling and rapid transport
- A muscle strain from heavy lifting
- Simple constipation that can be managed without urgency
Correct answer: A possible leaking or ruptured abdominal aortic aneurysm requiring gentle handling and rapid transport
A possible leaking or ruptured abdominal aortic aneurysm is correct because sudden abdominal and back pain with a pulsating mass and hypotension is a classic, time-critical presentation requiring minimal handling and rapid transport. Constipation, muscle strain, and indigestion do not produce shock and a pulsating abdominal mass, and treating them as benign would be fatal.
- An AEMT responds to a person found unresponsive who has snoring respirations and a strong odor of alcohol, but a glucose check reads 35 mg/dL. What clinical-judgment lesson does this finding reinforce?
- Assume any unresponsive patient who smells of alcohol is simply drunk
- Defer the glucose check until the patient sobers up
- Trust the odor of alcohol as a reliable indicator of the cause
- Always check a blood glucose in an altered patient rather than assuming intoxication is the cause
Correct answer: Always check a blood glucose in an altered patient rather than assuming intoxication is the cause
Always checking a blood glucose in an altered patient rather than assuming intoxication is correct because a treatable cause like hypoglycemia is easily masked by the assumption of drunkenness. Trusting the alcohol odor, deferring the glucose check, or assuming intoxication all risk missing a reversible, life-threatening problem and represent the trap of premature closure.
- An AEMT delivers a newborn in the field. After drying and stimulation, the baby has a weak cry, slow breathing, and a heart rate counted at about 80 per minute. What is the most appropriate immediate action?
- Begin positive-pressure ventilation, because a newborn heart rate below 100 with poor breathing requires assisted ventilation
- Begin chest compressions immediately without assisting ventilation
- Clamp and cut the cord and then wait to see if the baby improves on its own
- Give the newborn oral glucose to raise the heart rate
Correct answer: Begin positive-pressure ventilation, because a newborn heart rate below 100 with poor breathing requires assisted ventilation
Beginning positive-pressure ventilation is correct because a newborn heart rate below 100 with inadequate breathing is the trigger for assisted ventilation, which is the most important neonatal resuscitation step. Compressions are added only if the heart rate stays below 60 despite effective ventilation, waiting wastes time, and oral glucose has no role in newborn resuscitation.
- An AEMT is caring for a woman in active labor when the baby's head delivers but the shoulders do not follow with the next contraction, and the head retracts against the perineum. What does the AEMT recognize and do first?
- Pull firmly downward on the baby's head to free the shoulders
- Tell the mother to stop pushing for several minutes and delay transport
- Push the head back in and wait for the next contraction
- Recognize possible shoulder dystocia, position the mother with hips flexed up onto the abdomen, and apply suprapubic pressure per protocol
Correct answer: Recognize possible shoulder dystocia, position the mother with hips flexed up onto the abdomen, and apply suprapubic pressure per protocol
Recognizing possible shoulder dystocia and positioning the mother with hips flexed onto the abdomen with suprapubic pressure is correct because these maneuvers help free the impacted shoulder without harming the infant. Pulling forcefully on the head can cause nerve injury, pushing the head back in is dangerous, and delaying without intervention risks the infant's oxygen supply.
- An AEMT assesses a young patient who is hyperventilating with anxiety, tingling fingers, and carpal spasm after an emotional argument, with normal oxygen saturation and no chest pain or risk factors. What clinical-judgment approach is most appropriate?
- Conclude immediately it is purely anxiety and refuse transport
- Have the patient breathe into a paper bag without any assessment
- Treat the patient as having a pulmonary embolism and give high-dose anticoagulants
- Provide calm reassurance and coaching to slow breathing while still assessing for any organic cause and transporting for evaluation
Correct answer: Provide calm reassurance and coaching to slow breathing while still assessing for any organic cause and transporting for evaluation
Providing calm reassurance and coaching to slow breathing while still assessing for organic causes and offering transport is correct because hyperventilation syndrome is a diagnosis of exclusion, and the AEMT must not miss a serious cause. Refusing transport, treating it as a pulmonary embolism, or the outdated paper-bag method without assessment all reflect poor judgment.
- An AEMT must distinguish between a patient's worsening congestive heart failure and an asthma exacerbation, since both present with shortness of breath and wheezing. Which finding most points toward congestive heart failure?
- A long history of asthma since childhood with no cardiac problems
- Complete relief after a single puff of a rescue inhaler
- Symptoms that appear only after exposure to pet dander
- Crackles at the lung bases, pink frothy sputum, swollen ankles, and a history of heart failure
Correct answer: Crackles at the lung bases, pink frothy sputum, swollen ankles, and a history of heart failure
Crackles at the lung bases, pink frothy sputum, ankle swelling, and a heart failure history most point toward congestive heart failure because these reflect fluid backing up into the lungs and body. A childhood asthma history, allergen-triggered symptoms, and rapid relief from a rescue inhaler all suggest reactive airway disease instead, and the distinction shapes whether CPAP and other supportive measures are used.
- An AEMT cares for a diabetic patient who is very drowsy with extremely high blood glucose, very dry mucous membranes, and signs of profound dehydration, but no fruity breath odor or deep rapid breathing. What does this presentation most likely represent?
- Acute hypoglycemia, requiring oral glucose
- A simple panic attack, requiring only reassurance
- A hyperglycemic hyperosmolar state, requiring fluid support and transport
- An allergic reaction, requiring epinephrine
Correct answer: A hyperglycemic hyperosmolar state, requiring fluid support and transport
A hyperglycemic hyperosmolar state is correct because very high glucose with profound dehydration and altered mental status, but without the ketoacidosis features of fruity breath and deep rapid breathing, characterizes this condition, which is managed with fluids and transport. Hypoglycemia would show low glucose, and allergy or panic do not match the metabolic picture.
- An AEMT is treating a patient who has chest pain and meets protocol for aspirin, but the patient reports an active stomach ulcer that has been bleeding. How should this information shape the decision?
- Recognize the bleeding ulcer as a relative contraindication, consult protocol or medical direction before giving aspirin, and document the concern
- Ignore the ulcer history entirely because chest pain takes priority
- Give a double dose of aspirin to ensure the heart is protected
- Substitute nitroglycerin for aspirin regardless of blood pressure
Correct answer: Recognize the bleeding ulcer as a relative contraindication, consult protocol or medical direction before giving aspirin, and document the concern
Recognizing the bleeding ulcer as a relative contraindication and consulting protocol or medical direction before giving aspirin is correct because aspirin can worsen active gastrointestinal bleeding, requiring a risk-benefit judgment. Doubling the dose, ignoring the history, or arbitrarily substituting nitroglycerin all bypass the careful weighing that sound clinical judgment demands.
- An AEMT is assessing whether an alert adult patient who refuses transport has the capacity to make that decision. Which finding best supports that the patient can refuse care?
- The patient is alert and oriented, understands the risks of refusing, and is not impaired by intoxication, hypoxia, or low blood sugar
- The patient simply states they do not want to go to the hospital
- The patient has a normal blood pressure reading only
- A family member confirms the patient is usually stubborn
Correct answer: The patient is alert and oriented, understands the risks of refusing, and is not impaired by intoxication, hypoxia, or low blood sugar
A patient who is alert and oriented, understands the risks of refusing, and is not impaired by intoxication, hypoxia, or low blood sugar best demonstrates decision-making capacity. A bare statement of refusal, a single normal vital sign, or a relative's opinion do not establish that the patient comprehends the consequences, which is the core of a valid informed refusal.
- An AEMT arrives first at a two-vehicle crash with four patients and assumes initial command. What is the most appropriate first leadership action before detailed treatment begins?
- Perform a scene size-up, request appropriate resources, and triage patients to match care to the most urgent needs
- Wait for a supervisor to arrive before doing anything
- Load all four patients into one ambulance immediately without triage
- Begin fully treating the first patient encountered and ignore the others
Correct answer: Perform a scene size-up, request appropriate resources, and triage patients to match care to the most urgent needs
Performing a scene size-up, requesting appropriate resources, and triaging patients is correct because effective EMS leadership at a multiple-patient scene means organizing the response and matching care to acuity before committing to one patient. Treating only the first patient, waiting passively, or loading everyone without triage all fail to manage the scene and resources responsibly.
- An AEMT is communicating with a deaf patient who is alert and stable. Which communication approach best supports an accurate assessment?
- Speak loudly and quickly while looking away to multitask
- Skip the history-taking because communication is difficult
- Face the patient in good lighting, use written notes or available interpretation, and confirm understanding before proceeding
- Rely entirely on a young child at the scene to interpret medical details
Correct answer: Face the patient in good lighting, use written notes or available interpretation, and confirm understanding before proceeding
Facing the patient in good lighting, using written notes or interpretation, and confirming understanding is correct because clear, patient-centered communication is essential for an accurate assessment of a deaf patient. Speaking loudly while looking away defeats lip-reading, relying on a child for medical interpretation is inappropriate, and skipping the history abandons a core part of care.
- An AEMT recognizes mid-call that an early working impression of simple intoxication was wrong after finding a head injury during reassessment. What does this situation best illustrate about clinical judgment?
- An initial impression should never be changed once it is formed
- Reassessment can reveal that an initial impression was incorrect, and the plan must be revised accordingly
- Sticking to the first impression demonstrates confidence and competence
- Reassessment is unnecessary once the patient is loaded for transport
Correct answer: Reassessment can reveal that an initial impression was incorrect, and the plan must be revised accordingly
This situation illustrates that reassessment can reveal an initial impression was incorrect and the plan must be revised, which is central to the iterative clinical-judgment cycle. Never changing an impression, skipping reassessment after loading, or rigidly defending the first guess all reflect anchoring bias and prevent the AEMT from catching dangerous errors.
- An AEMT is treating a stable patient with an isolated, painful, swollen, deformed wrist after a fall, with a good distal pulse, normal sensation, and good movement of the fingers. What is the most appropriate management?
- Apply a tourniquet above the wrist to control swelling
- Forcefully straighten the wrist to its normal anatomical position before splinting
- Leave the wrist unsplinted and let it move freely during transport
- Splint the injury in the position found, support distal circulation, and reassess pulse, motor, and sensory function after splinting
Correct answer: Splint the injury in the position found, support distal circulation, and reassess pulse, motor, and sensory function after splinting
Splinting in the position found, supporting circulation, and reassessing pulse, motor, and sensory function is correct because immobilizing a stable, well-perfused extremity injury reduces pain and prevents further damage while monitoring for changes. Forcefully straightening it, leaving it unsplinted, or applying a tourniquet for swelling all risk harm to a limb that has good circulation and sensation.
- An AEMT cares for a patient with a large partial-thickness burn to the arm that occurred 10 minutes ago. The burn area is still warm. What is the most appropriate initial care for the burn itself?
- Cover the burn with ice packs for the entire transport
- Stop the burning process, cool the area briefly with room-temperature water, then cover with a dry sterile dressing
- Break any blisters to relieve the pressure
- Apply butter or ointment to soothe the burned skin
Correct answer: Stop the burning process, cool the area briefly with room-temperature water, then cover with a dry sterile dressing
Stopping the burning process, cooling briefly with room-temperature water, and covering with a dry sterile dressing is correct because brief cooling halts tissue damage while a dry sterile cover protects the wound and limits heat loss. Butter or ointment trap heat and contaminate, prolonged ice causes further tissue injury and hypothermia, and breaking blisters increases infection risk.
- An AEMT is treating a patient who suddenly develops difficulty breathing and a drop in blood pressure after a stinging insect sting, but has only mild local swelling at the sting site and no hives. How should the AEMT interpret the systemic symptoms?
- Withhold epinephrine because the visible reaction at the site is small
- Treat the breathing difficulty and hypotension as anaphylaxis and prepare to give intramuscular epinephrine per protocol, since systemic signs define severity
- Conclude it is a minor local reaction because there are no hives
- Assume the symptoms are unrelated to the sting
Correct answer: Treat the breathing difficulty and hypotension as anaphylaxis and prepare to give intramuscular epinephrine per protocol, since systemic signs define severity
Treating the breathing difficulty and hypotension as anaphylaxis and preparing intramuscular epinephrine per protocol is correct because systemic signs such as respiratory compromise and shock define a severe reaction regardless of the local appearance. Calling it minor, withholding epinephrine because the site looks small, or dismissing the connection all underestimate a life-threatening reaction.
- An AEMT places an oropharyngeal airway in an unresponsive patient, but the patient begins to gag and push it out. What does this response indicate and what should the AEMT do?
- Conclude the patient no longer needs any airway management
- Insert a larger oral airway to overcome the gagging
- Force the oral airway back in and tape it in place
- The gag reflex is present, so remove the oral airway and consider a nasopharyngeal airway instead while managing the airway manually
Correct answer: The gag reflex is present, so remove the oral airway and consider a nasopharyngeal airway instead while managing the airway manually
Recognizing that an intact gag reflex means the oral airway should be removed and a nasopharyngeal airway considered is correct because an oropharyngeal airway is only tolerated when the gag reflex is absent. Forcing it back in risks vomiting and aspiration, abandoning airway management ignores the need, and a larger oral airway worsens the gagging.
- An AEMT is treating a patient who fainted while standing in church and is now fully alert with normal vital signs, a normal glucose, and no injuries. Bystanders describe a brief loss of consciousness with quick spontaneous recovery. What does measured clinical judgment support?
- Diagnose a stroke and rush the patient to a stroke center
- Tell the patient it was definitely harmless and leave without offering transport
- Administer epinephrine for the fainting episode
- Treat this as likely vasovagal syncope but still offer transport for evaluation, since syncope can have serious causes
Correct answer: Treat this as likely vasovagal syncope but still offer transport for evaluation, since syncope can have serious causes
Treating it as likely vasovagal syncope while still offering transport for evaluation is correct because, although the episode appears benign, syncope can stem from cardiac or other dangerous causes that the field cannot exclude. Diagnosing a stroke without focal signs, giving epinephrine, or guaranteeing it was harmless all misjudge an uncertain presentation.
- An AEMT cares for a child who had a brief generalized seizure that has now stopped, associated with a high fever from an ear infection. The child is now postictal but breathing adequately. What is the most appropriate AEMT approach?
- Support the airway, protect from injury, manage the fever passively, reassure the family, and transport for evaluation
- Conclude no transport is needed because febrile seizures are always harmless
- Force oral fever medication into the still-drowsy child immediately
- Restrain the child to prevent another seizure
Correct answer: Support the airway, protect from injury, manage the fever passively, reassure the family, and transport for evaluation
Supporting the airway, protecting from injury, managing the fever passively, reassuring the family, and transporting is correct because a febrile seizure is usually self-limited but the child needs evaluation for the source of fever and monitoring. Forcing medication into a drowsy child risks aspiration, restraint is unnecessary, and assuming no transport is needed dismisses the need to identify the cause.
- An AEMT is treating a patient who improved after a nebulized bronchodilator but now reports a racing heartbeat and mild tremor. The breathing is better and oxygen saturation has risen. How should the AEMT interpret these new symptoms?
- Recognize the racing heart and tremor as expected side effects of the bronchodilator, continue to monitor, and reassure the patient
- Conclude the medication is harmful and never use it again on any patient
- Give a sedative to slow the heart rate
- Stop all treatment and assume the patient is having a heart attack
Correct answer: Recognize the racing heart and tremor as expected side effects of the bronchodilator, continue to monitor, and reassure the patient
Recognizing the racing heart and tremor as expected side effects of the bronchodilator, monitoring, and reassuring the patient is correct because beta-agonist medications commonly cause tachycardia and tremor while improving breathing. Assuming a heart attack, abandoning a helpful medication, or adding a sedative all misread predictable, generally benign side effects in a patient who is improving.
- An AEMT is en route to a call for 'difficulty breathing' at a residence and reviews the dispatch details. What is the most appropriate use of clinical judgment during this en-route phase?
- Form preliminary expectations, mentally review relevant protocols, and prepare oxygen and airway equipment so care can begin immediately on arrival
- Assume the call is routine and avoid preparing any equipment
- Plan to skip the primary survey to save time on arrival
- Decide the exact diagnosis and treatment plan from the dispatch text alone
Correct answer: Form preliminary expectations, mentally review relevant protocols, and prepare oxygen and airway equipment so care can begin immediately on arrival
Forming preliminary expectations, reviewing relevant protocols, and preparing oxygen and airway equipment is correct because the en-route phase is for anticipating likely problems and readying resources without locking in a diagnosis. Deciding the diagnosis from dispatch alone, failing to prepare, or planning to skip the primary survey all undermine readiness and safe assessment.
- An AEMT is treating a patient in shock and starts a normal saline bolus, but during reassessment the patient develops increasing shortness of breath and crackles in the lungs. What does this finding require?
- Increase the fluid rate to push through the resistance
- Slow or stop the fluid, support breathing, and reassess, since the crackles suggest fluid is overloading the lungs
- Ignore the crackles and continue the bolus unchanged
- Lay the patient flat to relieve the breathing difficulty
Correct answer: Slow or stop the fluid, support breathing, and reassess, since the crackles suggest fluid is overloading the lungs
Slowing or stopping the fluid, supporting breathing, and reassessing is correct because new crackles and worsening dyspnea during a bolus suggest fluid overload, and continuing would worsen pulmonary congestion. Increasing the rate, ignoring the crackles, or laying the patient flat all aggravate the developing pulmonary edema and reflect failure to evaluate the treatment's effect.
- An AEMT is reassessing patients during transport and must decide how often to recheck vital signs. The patient is unstable with abnormal vital signs and a deteriorating condition. What reassessment interval reflects sound clinical judgment?
- Reassess the unstable patient every 15 minutes, the same as a stable patient
- Reassess only when the patient complains of something new
- Reassess the unstable patient at least every 5 minutes, and more often if the condition continues to change
- Reassess the unstable patient only once at the start of transport
Correct answer: Reassess the unstable patient at least every 5 minutes, and more often if the condition continues to change
Reassessing an unstable patient at least every 5 minutes, and more often if the condition changes, reflects sound judgment because frequent reassessment catches deterioration early and guides intervention. A single reassessment, a 15-minute interval suited to stable patients, or waiting for the patient to report a change all leave a deteriorating patient inadequately monitored.
- An AEMT is treating a patient with a sucking chest wound from a stabbing who is short of breath. After applying an occlusive dressing, the patient's breathing worsens and the neck veins become distended. What should the AEMT consider and do?
- Lay the patient flat and apply firm pressure over the chest
- Apply a second occlusive dressing over the first to seal it tighter
- Suspect a developing tension pneumothorax, briefly lift or burp the occlusive dressing to release trapped air, and reassess
- Remove all dressings and leave the wound completely open
Correct answer: Suspect a developing tension pneumothorax, briefly lift or burp the occlusive dressing to release trapped air, and reassess
Suspecting a developing tension pneumothorax and briefly lifting or burping the occlusive dressing to release trapped air is correct because a fully sealed open chest wound can trap air under pressure, and momentarily releasing the seal relieves it. Adding a tighter seal worsens the pressure, leaving the wound fully open is uncontrolled, and firm chest pressure does not address trapped air.
- An AEMT cares for a patient with a possible spinal injury who is fully alert, sober, has no distracting injuries, denies neck or back pain, and has no neurologic deficits, meeting the local protocol criteria for selective spinal motion restriction. What does protocol-guided judgment support?
- Immobilize every trauma patient on a long backboard regardless of assessment
- Let the patient decide whether to be immobilized without applying any criteria
- Base the decision solely on the mechanism of injury and skip the exam
- Apply the local selective spinal motion restriction protocol, which may permit forgoing full immobilization when all criteria are met
Correct answer: Apply the local selective spinal motion restriction protocol, which may permit forgoing full immobilization when all criteria are met
Applying the local selective spinal motion restriction protocol, which may permit forgoing full immobilization when criteria are met, is correct because modern protocols use assessment findings rather than blanket backboarding. Immobilizing everyone regardless of findings, deciding on mechanism alone, or leaving the choice entirely to the patient all bypass the structured criteria that guide this decision.
- An AEMT is treating a patient with severe difficulty breathing and applies CPAP per protocol, but the patient's blood pressure begins to fall and the patient becomes more lethargic. What does sound clinical judgment require?
- Add a second tight strap to ensure the mask cannot be removed
- Increase the CPAP pressure to force more air in
- Reassess and consider removing CPAP, since falling blood pressure and lethargy can be worsened by CPAP and may signal the patient is failing
- Keep the CPAP in place unchanged despite the deterioration
Correct answer: Reassess and consider removing CPAP, since falling blood pressure and lethargy can be worsened by CPAP and may signal the patient is failing
Reassessing and considering removing CPAP is correct because hypotension and declining mental status can be aggravated by CPAP and indicate the patient may be failing and need assisted ventilation instead. Increasing the pressure, leaving the device unchanged during deterioration, or tightening the mask all ignore the signs that the current treatment is not working.
- An AEMT is treating a patient with chest pain whose only abnormal finding is reproducible tenderness when the chest wall is pressed. The patient still reports the discomfort. How should this finding shape the AEMT's working impression?
- Definitively rule out any cardiac cause and cancel transport
- Note the reproducible tenderness as a feature that may suggest a musculoskeletal cause, but continue to treat conservatively and transport since a cardiac cause cannot be excluded in the field
- Ignore the chest pain entirely because it is reproducible
- Discharge the patient on scene after documenting the tenderness
Correct answer: Note the reproducible tenderness as a feature that may suggest a musculoskeletal cause, but continue to treat conservatively and transport since a cardiac cause cannot be excluded in the field
Noting reproducible tenderness as a possible musculoskeletal feature while still treating conservatively and transporting is correct because field findings inform but cannot exclude a cardiac cause. Ruling out cardiac disease, ignoring the pain, or discharging the patient on scene all overstep what prehospital assessment can establish and risk missing a serious condition.
- An AEMT cares for a trauma patient whose only obvious injury is a dramatic, bleeding scalp laceration, but the patient is also confused with shallow breathing. Which problem should the AEMT address first?
- Both problems at exactly the same time regardless of resources
- The scalp laceration, because it is bleeding the most visibly
- The shallow breathing and altered mental status, because airway and breathing threats outrank a dramatic but non-life-threatening scalp wound
- Neither problem until arrival at the hospital
Correct answer: The shallow breathing and altered mental status, because airway and breathing threats outrank a dramatic but non-life-threatening scalp wound
Addressing the shallow breathing and altered mental status first is correct because airway and breathing are the highest priorities in the primary survey, outranking an attention-grabbing but survivable scalp wound. Treating the bleeding scalp first, attempting everything at once, or deferring all care to the hospital all let a dramatic injury distract from the true life threat.
- An AEMT is treating an unresponsive hypoglycemic patient with a glucose of 30 mg/dL who cannot protect the airway, and IV access cannot be obtained after two attempts. The patient is still breathing. What in-scope action best fits this situation?
- Withhold all glucose treatment because the IV attempts failed
- Administer intramuscular glucagon per protocol while continuing to manage the airway, since IV access is unavailable
- Wait for a paramedic to arrive before providing any glucose
- Place oral glucose gel into the unresponsive patient's mouth
Correct answer: Administer intramuscular glucagon per protocol while continuing to manage the airway, since IV access is unavailable
Administering intramuscular glucagon per protocol while managing the airway is correct because glucagon provides a needle-into-muscle route that does not require a vein when IV access fails in a profoundly hypoglycemic, unresponsive patient. Oral glucose risks aspiration in an unprotected airway, and waiting for a paramedic or withholding treatment leaves dangerous hypoglycemia untreated.
- An AEMT cares for a patient with a partial amputation of two fingers from a saw. Bleeding is controlled with direct pressure, and the severed fingertips are recovered. How should the AEMT manage the amputated parts during transport?
- Wrap the amputated parts in moist sterile gauze, seal them in a bag, and keep them cool on top of ice without freezing or direct ice contact
- Discard the amputated parts since reattachment is unlikely
- Place the amputated parts directly on ice so they freeze solid
- Soak the amputated parts in water for the entire transport
Correct answer: Wrap the amputated parts in moist sterile gauze, seal them in a bag, and keep them cool on top of ice without freezing or direct ice contact
Wrapping the amputated parts in moist sterile gauze, sealing them in a bag, and keeping them cool on ice without freezing or direct ice contact is correct because this preserves the tissue for possible reattachment without freezing damage. Direct freezing destroys the tissue, discarding the parts removes the chance of reattachment, and prolonged soaking macerates the tissue.
- An AEMT is treating a patient who was sprayed with an unknown industrial chemical and is contaminated. The patient is symptomatic but the substance is still on the skin and clothing. What is the most appropriate clinical-judgment priority before detailed treatment?
- Ensure responder safety and decontaminate the patient by removing contaminated clothing and flushing the skin before extensive hands-on care
- Transport immediately without any decontamination to save time
- Apply a neutralizing chemical directly to the contaminated skin
- Begin a full secondary assessment while the chemical remains on the skin
Correct answer: Ensure responder safety and decontaminate the patient by removing contaminated clothing and flushing the skin before extensive hands-on care
Ensuring responder safety and decontaminating the patient by removing contaminated clothing and flushing the skin before extensive care is correct because ongoing chemical exposure harms the patient and contaminating responders endangers the whole crew. Doing a hands-on secondary assessment over contamination, transporting without decontamination, or applying a neutralizer all risk continued injury and crew exposure.
- An AEMT is treating an elderly patient on a blood thinner who struck the head in a low-speed fall and is currently alert with normal vital signs and no obvious injury. What clinical-judgment concern should most influence the plan?
- Withhold transport because the vital signs are normal
- Treat it as a minor bump and recommend the patient stay home
- Recognize the heightened risk of delayed intracranial bleeding due to anticoagulation, monitor closely for any change, and transport for evaluation
- Assume no serious injury is possible because the patient is currently alert
Correct answer: Recognize the heightened risk of delayed intracranial bleeding due to anticoagulation, monitor closely for any change, and transport for evaluation
Recognizing the heightened risk of delayed intracranial bleeding due to anticoagulation, monitoring closely, and transporting for evaluation is correct because blood thinners can cause bleeding inside the skull that develops over hours even after a minor head impact. Assuming no injury because the patient is alert, calling it a minor bump, or withholding transport all dangerously underestimate the anticoagulated patient.
- An AEMT is treating a marathon runner found collapsed on a hot day. The patient is confused, has hot skin that is no longer sweating, a rectal temperature of 41 degrees Celsius (about 106 degrees Fahrenheit), a heart rate of 138, and a blood pressure of 96/54. Recognizing this as heat stroke, what is the most appropriate immediate AEMT priority?
- Administer aspirin to reduce the elevated temperature
- Begin aggressive active cooling, such as cold-water or ice-pack application to the neck, axillae, and groin, while supporting the airway and transporting
- Give oral fluids and have the patient rest in place until the temperature normalizes
- Wrap the patient in blankets to prevent further heat loss
Correct answer: Begin aggressive active cooling, such as cold-water or ice-pack application to the neck, axillae, and groin, while supporting the airway and transporting
Aggressive active cooling, such as cold-water or ice-pack application to the neck, axillae, and groin while supporting the airway and transporting, is the priority because heat stroke with altered mental status and hot, dry skin is a life threat where rapid temperature reduction limits organ injury. Wrapping in blankets traps heat, oral fluids are inadequate and risky in a confused patient, and aspirin does not treat environmental hyperthermia. Cooling is the time-critical action.
- An AEMT is treating an anxious 22-year-old who began breathing rapidly and deeply after an argument, now reporting tingling around the mouth and cramping in the hands, with a normal oxygen saturation and clear lungs. Recognizing likely hyperventilation, what does sound clinical judgment support?
- Have the patient breathe into a paper bag immediately as the definitive treatment
- Provide calm coaching to slow the breathing while still considering and screening for serious causes such as hypoxia, metabolic acidosis, or pulmonary embolism before settling on a benign explanation
- Withhold all oxygen and supportive care because the saturation is normal
- Conclude the cause is purely psychological and decline to assess further
Correct answer: Provide calm coaching to slow the breathing while still considering and screening for serious causes such as hypoxia, metabolic acidosis, or pulmonary embolism before settling on a benign explanation
Providing calm coaching while still screening for serious causes such as hypoxia, metabolic acidosis, or pulmonary embolism is the sound approach because rapid breathing can be psychogenic or a compensatory sign of a dangerous underlying problem, and the AEMT should not close prematurely. Paper-bag rebreathing is outdated and risky, assuming a purely psychological cause skips analysis of cues, and a normal saturation alone does not exclude a serious diagnosis. Judgment balances reassurance with continued vigilance.
- An AEMT is treating a critically injured trauma patient in a remote rural area more than 60 minutes by ground from the nearest trauma center, and an air-medical helicopter is available. What clinical-judgment factor most appropriately drives the decision to request air transport?
- Whether the ground crew is tired and would rather not drive
- Whether air transport will meaningfully shorten time to definitive surgical care for a patient who meets trauma criteria, weighed against weather and scene safety
- Whether the helicopter looks more impressive to bystanders on scene
- Whether the patient personally prefers to ride in a helicopter
Correct answer: Whether air transport will meaningfully shorten time to definitive surgical care for a patient who meets trauma criteria, weighed against weather and scene safety
Whether air transport will meaningfully shorten time to definitive surgical care for a trauma-criteria patient, weighed against weather and scene safety, is the factor that drives the decision because the goal is faster access to a trauma center when ground transport is prolonged. Bystander impressions, patient preference for the aircraft, or crew fatigue are not valid clinical reasons. The decision turns on time savings and safety.
- An AEMT is managing a critically ill patient who needs medication and fluids, but after two failed peripheral IV attempts and with the patient rapidly deteriorating, no vein is accessible. Protocol authorizes intraosseous access. What does clinical judgment support?
- Establish intraosseous access per protocol to deliver fluids and authorized medications without further delay
- Continue attempting peripheral IVs indefinitely until one succeeds
- Abandon all vascular access for the remainder of the call
- Wait for the patient to lose pulses before considering any access
Correct answer: Establish intraosseous access per protocol to deliver fluids and authorized medications without further delay
Establishing intraosseous access per protocol is the appropriate choice because a deteriorating patient who needs fluids and medications cannot wait for repeated failed peripheral attempts, and intraosseous access is within the AEMT scope where authorized. Endlessly retrying peripheral IVs wastes time, abandoning access ignores the need, and waiting for cardiac arrest forfeits the chance to intervene early. The failed attempts trigger the move to the alternative route.
- An AEMT arrives to find a combative, agitated patient who is shouting but has made no physical threats. The scene is otherwise safe and the patient has normal vital signs and a normal glucose. What communication approach best reflects sound clinical judgment?
- Match the patient's volume by shouting back to assert control
- Use calm verbal de-escalation, maintain a safe distance and clear exit, speak in short reassuring statements, and avoid confrontational body language
- Immediately apply physical restraints to control the patient
- Crowd close to the patient to demonstrate that the crew is in charge
Correct answer: Use calm verbal de-escalation, maintain a safe distance and clear exit, speak in short reassuring statements, and avoid confrontational body language
Calm verbal de-escalation with a safe distance, a clear exit, short reassuring statements, and non-confrontational body language is the best approach because most agitated patients can be settled without force, and communication is a core clinical-judgment skill. Immediate restraints are reserved for danger after de-escalation fails, shouting escalates conflict, and crowding the patient provokes aggression. Verbal techniques come first.
- An AEMT is the lead provider on a chaotic multi-patient scene with two crew members and an arriving first-responder unit. Applying the leadership component of clinical judgment, what is the most effective action?
- Personally perform all assessments and interventions while the others stand by
- Let each responder decide independently what to do without coordination
- Delay assigning any roles until every patient has been fully assessed
- Assign clear, specific roles to each responder, communicate priorities, and coordinate the team rather than trying to perform every task personally
Correct answer: Assign clear, specific roles to each responder, communicate priorities, and coordinate the team rather than trying to perform every task personally
Assigning clear, specific roles, communicating priorities, and coordinating the team is the most effective action because leadership in an EMS response means organizing resources so that the most urgent needs are met efficiently. Trying to do everything alone overwhelms the lead and slows care, uncoordinated independent action creates gaps and duplication, and delaying role assignment wastes available help. Team coordination is the leadership task.
- An AEMT is reassessing an otherwise healthy adult patient and notes a resting heart rate of 38 with new dizziness, pale skin, and a blood pressure of 84/50. Recognizing symptomatic bradycardia, what does the AEMT's scope and judgment support?
- Apply transcutaneous pacing to the patient
- Reassure the patient that a slow heart rate is always harmless and delay transport
- Support oxygenation, position the patient appropriately, monitor closely, and transport rapidly for higher-level care, since AEMTs cannot give cardiac drugs or pace the heart
- Administer atropine intravenously to raise the heart rate
Correct answer: Support oxygenation, position the patient appropriately, monitor closely, and transport rapidly for higher-level care, since AEMTs cannot give cardiac drugs or pace the heart
Supporting oxygenation, positioning, monitoring, and transporting rapidly is correct because symptomatic bradycardia with hypotension and dizziness needs prompt higher-level care, and atropine and transcutaneous pacing are beyond the AEMT scope. Calling a slow rate always harmless ignores the symptoms of poor perfusion. The AEMT provides supportive care and recognizes the need for paramedic or hospital-level intervention.
- An AEMT is called for a dialysis patient who missed a session and now has generalized weakness, nausea, and on the monitor shows peaked T waves with a widening complex. Recognizing a likely electrolyte emergency, what does clinical judgment support within the AEMT scope?
- Suspect hyperkalemia, provide supportive care and oxygen, monitor closely for rhythm deterioration, and transport rapidly while requesting paramedic-level care
- Slow transport because the patient is still conscious and talking
- Give oral glucose to correct the electrolyte problem
- Administer a large fluid bolus to dilute the potassium
Correct answer: Suspect hyperkalemia, provide supportive care and oxygen, monitor closely for rhythm deterioration, and transport rapidly while requesting paramedic-level care
Suspecting hyperkalemia, providing supportive care and oxygen, monitoring for rhythm deterioration, and transporting rapidly while requesting paramedic-level care is the sound approach because a missed dialysis session with peaked T waves and a widening complex points to dangerous potassium elevation that AEMTs cannot definitively treat. A fluid bolus and oral glucose do not address the electrolyte threat, and a conscious patient can still deteriorate suddenly. Recognition drives urgent transport and escalation.
- An AEMT is treating a hiker bitten on the forearm by a pit viper who now has localized swelling, pain, and two puncture marks. Applying clinical judgment within the AEMT scope, what is the most appropriate management?
- Apply a tight arterial tourniquet above the bite to trap the venom
- Keep the patient calm, immobilize the limb at heart level, remove rings and constricting items, mark swelling progression, and transport promptly
- Cut the wound and attempt to suck out the venom
- Apply ice directly to the bite to slow venom spread
Correct answer: Keep the patient calm, immobilize the limb at heart level, remove rings and constricting items, mark swelling progression, and transport promptly
Keeping the patient calm, immobilizing the limb at heart level, removing constricting items, marking swelling progression, and transporting promptly is correct because these measures preserve circulation while definitive antivenom care occurs at the hospital. The affected limb should never be placed below heart level, as that promotes venom pooling and worsens local tissue injury. Arterial tourniquets, incision and suction, and direct ice are outdated and can worsen tissue injury, so supportive immobilization and prompt transport are the appropriate field actions.
- An AEMT responds to a family found together with headache, nausea, dizziness, and confusion inside a home with a running gas furnace, and a pulse oximeter reads a normal 98 percent. What does clinical judgment most suggest, and what is the priority?
- Suspect carbon monoxide poisoning, recognize that standard pulse oximetry can read falsely normal, move everyone to fresh air, and apply high-concentration oxygen
- Trust the normal pulse-oximetry reading and rule out any toxic gas exposure
- Assume a shared viral illness because multiple people are sick
- Treat each person individually inside the home before considering the environment
Correct answer: Suspect carbon monoxide poisoning, recognize that standard pulse oximetry can read falsely normal, move everyone to fresh air, and apply high-concentration oxygen
Suspecting carbon monoxide poisoning, recognizing that standard pulse oximetry can read falsely normal, moving everyone to fresh air, and applying high-concentration oxygen is correct because multiple people sick in one enclosed space with a combustion source is a classic carbon monoxide pattern that a standard oximeter cannot detect. Trusting the normal reading, treating people inside the hazard, or assuming a virus all miss the toxic exposure. Removal from the source and oxygen are the priorities.
- An AEMT has formed a working impression of simple anxiety in a patient with chest tightness, but during reassessment the patient develops diaphoresis, a dropping blood pressure, and an irregular pulse. According to the clinical-judgment cycle, what is the AEMT's most appropriate response to these new cues?
- Defer any change until the receiving hospital re-evaluates the patient
- Stop reassessing so the initial impression is not contradicted
- Treat the new findings as a higher-acuity possibility, escalate care and monitoring, and revise the plan toward a potential cardiac emergency
- Hold to the anxiety impression because it was decided first
Correct answer: Treat the new findings as a higher-acuity possibility, escalate care and monitoring, and revise the plan toward a potential cardiac emergency
Treating the new findings as a higher-acuity possibility, escalating care, and revising the plan toward a potential cardiac emergency is correct because diaphoresis, falling pressure, and an irregular pulse are red-flag cues that should override an initial benign impression. Clinging to the first impression, deferring to the hospital, or stopping reassessment all ignore the iterative nature of clinical judgment. New cues reopen the cycle.
- An AEMT is treating a patient who is hypotensive and cool with flat neck veins after blunt trauma, then encounters a second mechanism question: a different patient who is hypotensive but has distended neck veins and muffled heart sounds. How does distinguishing these two pictures shape the AEMT's clinical judgment?
- Neither finding affects the field plan, so both should simply be transported slowly
- The neck veins are irrelevant and only the blood pressure should guide care
- Both pictures are identical and call for the same large fluid bolus only
- The flat-neck-vein, cool patient suggests hypovolemic hemorrhage favoring fluid support, while distended neck veins with muffled tones suggest an obstructive cause requiring rapid transport for definitive care
Correct answer: The flat-neck-vein, cool patient suggests hypovolemic hemorrhage favoring fluid support, while distended neck veins with muffled tones suggest an obstructive cause requiring rapid transport for definitive care
Recognizing that flat neck veins with cool skin suggest hypovolemic hemorrhage favoring fluid support, while distended neck veins with muffled heart tones suggest an obstructive cause needing rapid transport for definitive care, is correct because the neck-vein finding helps differentiate shock types and directs different priorities. Treating both identically, ignoring the findings, or relying on blood pressure alone misses the analytical step. Analyzing these cues shapes the plan.
