This free AEMT study guide walks through the highest-yield content the Advanced EMT cognitive exam tests, organized by the six official content areas in the AEMT Examination Specifications — and taught to the .[1]
It is interactive, not a wall of text: every domain has worked field scenarios, assessment and treatment tables, labeled diagrams, and built-in flashcards, taught at the Advanced EMT level the exam actually tests — recognizing and treating emergencies with IV access, supraglottic airways, and a limited drug list, then escalating to ALS when needed.
Read it domain by domain, then round out your prep with our practice questions and flashcards. The AEMT bridges basic life support and advanced life support —more than an EMT, but not yet a Paramedic.
AEMT Exam Snapshot
| Detail | AEMT (NREMT) exam |
|---|---|
| Items | 135 total (100 scored + 35 unscored pilot) |
| Format | Fixed-length linear computer-based test (NOT adaptive) |
| Time limit | 3 hours |
| Passing standard | Pass/Fail vs a criterion-referenced cut score; no fixed % |
| Exam fee | About $159 (dated anchor — verify on nremt.org) |
| Eligibility | Current EMT cert + a state-approved AEMT course (often CAAHEP/CoAEMSP) |
| Certification period | 2 years; renew by NCCP continuing education + a state license |

(31–35%) and Medical/OB-GYN (25–29%) together make up over half the exam. The remaining items split across Cardiology & Resuscitation, Airway, Trauma, and EMS Operations. Pediatric content is woven through every domain, so you cannot study peds as a separate block. Budget your time toward the heaviest domains first.[1]
Bars show the midpoint of each official range; the exam draws each domain from within its published band. Pediatric items are distributed across all domains rather than weighted separately.[1]
AEMT Scope & How the Exam Is Built
The AEMT is one of four national EMS levels in the : EMR, EMT, AEMT, and Paramedic.[4] Each level builds on the one below it. The AEMT adds advanced skills to the EMT’s basic life support but stops well short of the Paramedic’s full advanced life support — and the exam tests you at exactly that level.
Concretely, the AEMT can establish peripheral IV and IO access, give IV crystalloid fluids, insert a , and administer a limited formulary — oxygen, oral glucose, aspirin, , for anaphylaxis, , , , and — per state protocol and .[4] The AEMT cannot intubate, interpret cardiac rhythms, or manually defibrillate; AEMTs apply an in arrest.
The cognitive exam measures entry-level competency across the National EMS Education Standards at the AEMT level.[5] Since July 1, 2024 it has been a fixed-length linear test of 135 items (not adaptive), and the largest single domain is now — the reasoning process of applying assessment findings to an evolving patient, not just recalling facts.[1]
Airway, Respiration & Ventilation
Airway is 9–13% of the exam, but it is the first priority on every patient.[1] The AEMT recurring task is recognizing inadequate breathing, supporting it with the right device, and advancing to a supraglottic airway when basic measures fail.
Assessing Breathing & Oxygenation
Adequate breathing has a normal rate (12–20 in adults), regular rhythm, good chest rise, and clear, equal lung sounds. Signs of inadequate breathing include a rate under 8 or over 24, shallow or irregular effort, accessory-muscle use, the tripod position, cyanosis, 1–2 word dyspnea, and altered mental status. Pulse oximetry (target SpO₂ ≥94%) and (end-tidal CO₂ 35–45 mmHg) quantify it — capnography detects respiratory depression earlier than SpO₂ and is not fooled by carbon monoxide.
| Device | Flow | Approx. FiO₂ | Use |
|---|---|---|---|
| Nasal cannula | 1–6 L/min | 24–44% | Mild hypoxia, talking patient |
| Simple mask | 6–10 L/min | 40–60% | Moderate hypoxia |
| Venturi mask | Varies | Precise (24–60%) | COPD — exact FiO₂ |
| Non-rebreather | 10–15 L/min | Up to ~90% | Significant hypoxia, breathing adequately |
| BVM | 15 L/min | Up to ~100% | Inadequate or absent breathing |
Oxygen, BVM & Basic Airways
Manage the airway in steps: position and suction (no more than 15 seconds per attempt), add an (only if no gag reflex) or (tolerated with a gag reflex; avoid with a suspected basilar skull fracture), then ventilate with a . Ventilate an adult once every 5–6 seconds (about 10–12/min) and a child or infant once every 2–3 seconds — do not over-ventilate, which raises intrathoracic pressure, lowers cardiac output, and causes gastric distension and aspiration. Titrate oxygen to SpO₂, and never withhold needed oxygen from a hypoxic COPD patient.
1–6 L/min (about 24–44% FiO₂) — mild hypoxia, talking patient
Moderate hypoxia; Venturi gives a precise FiO₂ (good for COPD)
10–15 L/min (about 90% FiO₂) — significant hypoxia, breathing adequately
Awake patient in distress (CHF, COPD/asthma) who can protect the airway
Inadequate or absent breathing — assist/deliver positive-pressure ventilation
When BVM fails — i-gel / King LT (AEMT advanced airway)
Supraglottic Airways & CPAP
When a BVM cannot maintain ventilation, the AEMT advances to a — the i-gel (a soft gel cuff, no inflation), the King LT (dual cuff), or the Combitube — confirming placement by chest rise, breath sounds, and capnography. Endotracheal intubation is Paramedic-level, not AEMT.
helps an awake, cooperative patient in distress from pulmonary edema (CHF) or a COPD/asthma exacerbation by keeping the airways open and reducing the work of breathing, often avoiding intubation. Contraindications: apnea or respiratory arrest, hypotension, a decreased level of consciousness or inability to protect the airway, vomiting, pneumothorax, and significant facial trauma.
Respiratory Emergencies
Asthma/COPD: wheezing from bronchospasm responds to nebulized ; a silent chest (loss of wheezing/air movement) in a tiring asthmatic is ominous. Stridor signals upper-airway obstruction (croup, epiglottitis, foreign body, anaphylaxis) — for suspected epiglottitis, keep the child calm and do not inspect the throat.
For a conscious choking adult, give abdominal thrusts; if they go unresponsive, begin CPR. Monitor sedated or opioid patients with capnography and reverse opioid respiratory depression with .
Checkpoint · Airway, Respiration & Ventilation
Question 1 of 10
When considering the use of CPAP in patients with respiratory distress, which of the following conditions is typically considered a contraindication?
Cardiology & Resuscitation
Cardiology & Resuscitation is 11–15% of the exam.[1] The AEMT recognizes acute coronary syndromes and gives early ACS care, runs high-quality CPR, and applies the AED — while understanding that rhythm interpretation and manual defibrillation belong to the Paramedic.
Acute Coronary Syndromes & Chest Pain
ranges from unstable angina to NSTEMI to a (a fully occluded artery). The classic presentation is crushing substernal pressure radiating to the arm or jaw with dyspnea, diaphoresis, and nausea — but it can be atypical in women, the elderly, and diabetics.
Assess pain with and take a history. AEMT care: oxygen if SpO₂ <94%, aspirin 162–324 mg chewed (no allergy or active bleed), and for ischemic pain.[8]
Cardiac Arrest & the Chain of Survival
Survival in cardiac arrest depends on the : early recognition and activation, early CPR, early defibrillation, advanced care, and post-arrest care. Every link the AEMT controls — recognition, compressions, and the AED — happens in the first minutes.
Recognize arrest and call for help / activate EMS
High-quality compressions: 100–120/min, at least 2 in deep
Apply the AED and shock a shockable rhythm
ALS interventions (Paramedic) — airway, drugs, monitoring
Optimize oxygenation, perfusion, and transport
High-Quality CPR & the AED
High-quality adult CPR is the highest-yield resuscitation content: compress at 100–120/min, at least 2 inches (5 cm) deep, allow full recoil, use a 30:2 ratio (one rescuer), switch compressors about every 2 minutes, and minimize interruptions.[6] Apply the as soon as it arrives, clear the patient, and shock a shockable rhythm; resume compressions immediately. A sudden rise in end-tidal CO₂ suggests .
| Parameter | Adult | Child / Infant |
|---|---|---|
| Compression rate | 100–120/min | 100–120/min |
| Compression depth | At least 2 in (5 cm) | About 1/3 the chest depth |
| Ratio (1 rescuer) | 30:2 | 30:2 |
| Ratio (2 rescuers) | 30:2 | 15:2 |
| First step for arrest | CPR + AED | CPR (bradycardia often = hypoxia) |
Heart Failure & Cardiogenic Shock
Acute pulmonary edema (CHF): dyspnea, crackles, pink frothy sputum, and jugular venous distension — sit the patient upright, give high-flow oxygen or CPAP, and assist with nitroglycerin per protocol. Cardiogenic shock is pump failure (often after a large MI): hypotension with pulmonary edema and cool, clammy skin — AEMT care is supportive (oxygen, careful positioning) with rapid transport, because the definitive treatment is beyond AEMT scope.
Checkpoint · Cardiology & Resuscitation
Question 1 of 10
Capnography is utilized during CPR to:
Trauma
Trauma is 7–11% of the exam.[1] The AEMT priorities are controlling life-threatening bleeding, recognizing and treating shock, supporting airway and breathing, and rapid transport of the critical trauma patient — minimizing on-scene time during the “golden period.”
Bleeding Control & Shock
Control severe external bleeding in order: direct pressure first, then a for uncontrolled extremity hemorrhage (applied high and tight, time noted) or wound packing/hemostatic gauze for junctional wounds. Recognize early — tachycardia, anxiety, pale cool clammy skin, and a narrowing pulse pressure appear before the blood pressure falls. AEMT care: control bleeding, give oxygen, keep the patient warm and supine, give IV crystalloid fluids per protocol, and transport rapidly.
Chest & Abdominal Trauma
Seal a sucking (open) chest wound with an occlusive (vented) dressing, and burp it if a develops (severe dyspnea, absent breath sounds one side, JVD, hypotension, late tracheal deviation). A flail chest (≥2 adjacent ribs broken in ≥2 places) causes paradoxical wall movement — support ventilation.
Suspect internal bleeding with a rigid or distended abdomen, bruising, and signs of shock. Stabilize an impaled object in place (do not remove), and cover an evisceration with a moist sterile dressing — never push organs back in.
Head & Spinal Injury
With a head injury, watch for rising intracranial pressure: a falling , unequal pupils, and the late Cushing’s triad (hypertension with a widening pulse pressure, bradycardia, irregular respirations) — maintain oxygenation and perfusion and transport. Use selectively (by criteria such as NEXUS — no midline tenderness, no focal deficit, normal alertness, no intoxication, no distracting injury), not automatically on every trauma patient.
Burns & Environmental Emergencies
For burns, stop the burning, remove jewelry and non-adhered clothing, cover with a dry sterile dressing, and keep the patient warm — do not pop blisters or apply ice or ointments. Estimate the area with the (head 9%, each arm 9%, each leg 18%, anterior trunk 18%, posterior trunk 18%, genitals 1%), and watch for airway burns (singed nasal hair, soot, hoarseness, stridor).[12]
Hypothermia: handle gently (rough movement can trigger ventricular fibrillation), remove wet clothing, rewarm passively, and give warm oxygen. Heat stroke (hot skin, altered mentation) needs rapid active cooling and transport.
Musculoskeletal Injuries
Splint fractures to reduce pain and bleeding, and always check distal circulation, motor, and sensory (CMS) function before and after splinting. An open fracture (bone through skin) carries infection and bleeding risk; a traction splint is for an isolated mid-shaft femur fracture.
Suspect compartment syndrome with pain out of proportion, pallor, and paresthesia — do not elevate or ice, and transport. For a pelvic fracture (major hemorrhage risk), use a pelvic binder, handle gently, and treat for shock.
Checkpoint · Trauma
Question 1 of 10
In managing a patient with a flail chest, the AEMT should understand that the underlying danger is:
Medical, Obstetrics & Gynecology
Medical/OB-GYN is the second-largest domain at 25–29%.[1] It spans altered mental status and diabetic emergencies, allergic reactions, stroke and seizures, toxicology, behavioral emergencies, and childbirth — and it is where the AEMT’s expanded drug list (dextrose, glucagon, epinephrine, naloxone, albuterol) earns its place.
Altered Mental Status & Diabetic Emergencies
For any altered patient, work the AEIOU-TIPS differential (Alcohol, Epilepsy, Insulin, Overdose, Uremia, Trauma, Infection, Psychiatric, Stroke) and always check a blood glucose. comes on fast with diaphoresis, tachycardia, and confusion: give oral glucose if the patient is conscious and can swallow, or or IM if not.[10] is hyperglycemia with deep rapid (Kussmaul) breathing, fruity breath, and dehydration — give IV fluids and transport.
Allergic Reactions & Anaphylaxis
Distinguish a mild allergic reaction (local hives, itching) from — a severe, rapid, multi-system reaction with airway swelling, wheezing or stridor, hypotension, and hives. The first-line treatment is intramuscular 1:1,000 into the lateral thigh (auto-injector 0.3 mg adult / 0.15 mg child), repeated in 5–15 minutes if needed, plus airway support, high-flow oxygen, IV fluids for shock, and albuterol for bronchospasm.
Stroke, Seizures & Other Medical
Screen for stroke with the (facial droop, arm drift, abnormal speech) — establish the last-known-well time, keep oxygenation and glucose normal, and transport to a stroke center.[9] For a seizure, protect from injury, do not restrain or put anything in the mouth, and protect the airway afterward; status epilepticus (≥5 minutes or repeated without recovery) is an emergency — benzodiazepines are typically Paramedic-level, so support and transport. Recognize sepsis (suspected infection plus poor perfusion) and give oxygen, fluids, and rapid transport.
Toxicology & Behavioral Emergencies
Recognize the common toxidromes: opioid (pinpoint pupils, respiratory depression → after supporting ventilation), sympathomimetic (tachycardia, hypertension, agitation, dilated pupils), and cholinergic/SLUDGE (salivation, lacrimation, urination, defecation, GI distress, emesis). Carbon monoxide reads a falsely normal SpO₂ — give high-flow oxygen and remove from the source.
For behavioral emergencies, ensure scene safety, stay calm, set limits, and use restraints only when necessary, monitored, and per protocol — never prone, to avoid positional asphyxia. Suspect excited delirium with severe agitation and hyperthermia (high risk of sudden death).
Obstetrics, Gynecology & the Newborn
In late pregnancy, transport tilted to the left side to avoid supine hypotensive syndrome. Distinguish (painless bright-red bleeding — no vaginal exam) from (painful bleeding, rigid uterus).
(hypertension, headache, visual changes after 20 weeks) can progress to eclamptic seizures.[11] For imminent delivery (crowning), prepare to deliver; relieve a prolapsed cord with knee-chest positioning and a gloved hand off the cord.
Assess the newborn with the score, but act on the heart rate — warm, dry, position, and stimulate; if it stays below 100, begin positive-pressure ventilation.
| Drug | Indication | Route / note |
|---|---|---|
| Oral glucose | Conscious hypoglycemia | Between cheek and gum; must be able to swallow |
| Dextrose (D10/D50) | Hypoglycemia, can't swallow | IV/IO — an AEMT advanced skill |
| Glucagon | Hypoglycemia, no IV access | IM/SQ — raises glucose from liver glycogen |
| Epinephrine 1:1,000 | Anaphylaxis | IM lateral thigh (0.3 mg adult / 0.15 mg child) |
| Naloxone | Opioid overdose | IN/IM/IV — support ventilation first |
| Albuterol | Bronchospasm (asthma/COPD) | Nebulized beta-2 agonist |
| Aspirin | Suspected ACS | 162–324 mg chewed; no allergy or active bleed |
| Nitroglycerin | Ischemic chest pain | SL; hold for low BP, PDE-5 inhibitor, RV MI |

Question 1 of 10
For a patient experiencing an acute stroke, the preferred method of oxygen delivery is:
EMS Operations
EMS Operations is 6–10% of the exam.[1] It covers everything around the patient: scene safety, mass-casualty triage and incident command, hazmat, ambulance operations, and the legal and ethical framework you work within.
Scene Size-up & Safety
Before patient contact, perform a scene size-up: confirm scene safety, take standard precautions (BSI — gloves, eye protection, gown, mask as needed), identify the mechanism or nature of illness, count the patients, and call for additional resources early. Your safety comes first — you cannot help if you become a patient. Choose an emergency move only when there is immediate danger, you cannot reach a critical patient, or you must access another patient; otherwise move patients with proper body mechanics (the power lift).
MCIs & START Triage
A mass-casualty incident is one whose needs exceed available resources. Use the to organize, and triage with — Simple Triage And Rapid Treatment — sorting patients by respirations, perfusion, and mental status. Re-triage as conditions change; JumpSTART is the pediatric version.
Simple Triage And Rapid Treatment — sort by Respirations, Perfusion, and Mental status
Hazmat & Special Operations
At a hazardous-materials scene, work the zones: the hot zone is the contamination area, the warm zone is the decontamination corridor, and the cold zone is the safe area where EMS stages and command operates. Do not enter the hot zone without proper PPE and training, and decontaminate before transport.
For extrication, the phases are gain access, assess/stabilize, disentangle, and remove — patient care drives the process. Activate air-medical transport for critical, time-sensitive patients with prolonged ground transport.
Ambulance Operations & Legal/Ethical
Operate the ambulance with due regard — slow at intersections (where most crashes happen) and wear seatbelts. Document care in an accurate, objective patient care report (a legal record that supports continuity of care).
Know the legal essentials: consent (expressed for a competent patient, implied for the unconscious), a competent adult’s right to refuse care (ensure informed refusal and document thoroughly), duty to act, abandonment (never leave a patient without transferring to equal/higher care), patient privacy (HIPAA), and honoring a valid advance directive or DNR. Report suspected abuse and other mandated conditions per state law.
Checkpoint · EMS Operations
Question 1 of 10
In the context of EMS operations, what is the primary purpose of utilizing the Incident Command System (ICS)?
Clinical Judgment
Clinical Judgment is the largest single domain at 31–35% and is woven through every scenario.[1] It is not a body system — it is the reasoning process of taking a structured assessment, interpreting the findings, acting within scope, and reassessing. The 2024 redesign weights the exam toward this higher-order thinking.
Patient Assessment Flow
Every call follows the same flow: scene size-up, then a primary assessment that finds and treats life threats in order — control massive bleeding, then Airway, Breathing, Circulation, Disability, and Exposure (XABCDE) — guided by your general impression (the immediate sick/not-sick judgment). Then a focused or rapid head-to-toe secondary assessment with vitals and a history, and ongoing reassessment — every 5 minutes for an unstable patient, every 15 for a stable one. Use and the to track mental status.
The Clinical Judgment Cycle
The exam frames clinical reasoning as a cycle: recognize cues → analyze cues → form a hypothesis → generate solutions → take action → evaluate outcomes, then loop. A new finding restarts the cycle. The skill the exam rewards is acting on a worsening trend (a narrowing pulse pressure, a falling GCS) before any single number looks alarming.
Identify the relevant signs, symptoms, and history
Connect and prioritize the findings
Decide what is most likely happening
List the possible interventions within your scope
Perform the highest-priority intervention
Reassess — did it help? Adjust the plan
Pediatric & Special-Population Judgment
Pediatric content is integrated across every domain, so peds judgment is its own clinical skill. Form a from-the-doorway impression with the (Appearance, Work of Breathing, Circulation to the skin).
Remember that children compensate well and then crash suddenly, and that bradycardia in a child usually means hypoxia — open the airway and oxygenate. Use the same reasoning for older adults and patients with disabilities, adjusting for baseline and atypical presentations.
Communication & Hand-off
Clinical judgment includes communicating it. Use closed-loop communication (repeat back orders to confirm understanding) and give a structured hand-off — SBAR (Situation, Background, Assessment, Recommendation) or MIST (Mechanism, Injuries, Signs, Treatment) — so nothing is lost when care transfers. Therapeutic communication with the patient and family is part of the Clinical Judgment and leadership content the exam now tests.

How to Use This Study Guide
Work through the guide one domain at a time. After each domain, check it off in the contents to raise your exam-readiness score, then drill the same content in our free practice questions and flashcards — active recall and timed practice are what move knowledge into exam-day performance.
- Weight your time by the blueprint. Clinical Judgment (31–35%) and Medical/OB-GYN (25–29%) are over half the exam — spend the most time there.
- Stay in the AEMT scope. The exam tests advanced skills — IV/IO, fluids, supraglottic airways, and select drugs — not Paramedic-level intubation, cardiac monitoring, or manual defibrillation.
- Think in scenarios. The 2024 exam rewards applying assessment findings to an evolving patient — recognize the cue, act within scope, and reassess.
- Don’t silo pediatrics. Peds content is woven through every domain; keep pediatric vitals and the PAT in mind on every topic.
- Memorize the high-yield numbers. CPR parameters, the rule of nines, epinephrine and glucose dosing, and the AEMT drug list show up again and again.

AEMT Study Guide FAQ
The NREMT AEMT cognitive exam has 135 items total — 100 scored plus 35 unscored pilot items — and you have up to 3 hours to complete it. Since the July 1, 2024 redesign it is a fixed-length linear computer-based test, so every candidate answers the same number of items, delivered at Pearson VUE testing centers.
No. Unlike the NREMT EMT exam, the current AEMT cognitive exam is a fixed-length linear computer-based test of 135 items — the number of questions does not change based on your answers. You also cannot return to a previous item once you submit it, so answer each one carefully before advancing.
There is no fixed passing percentage. The AEMT exam is pass or fail against a criterion-referenced cut score set through a formal standard-setting study by EMS subject-matter experts and approved by the NREMT Board of Directors. Only the 100 scored items count, and unanswered items are scored as incorrect, so answer every question.
Six content areas: Clinical Judgment (31–35%), Medical/Obstetrics & Gynecology (25–29%), Cardiology & Resuscitation (11–15%), Airway, Respiration & Ventilation (9–13%), Trauma (7–11%), and EMS Operations (6–10%). Clinical Judgment and Medical/OB-GYN together are over half the exam. Pediatric content is integrated throughout rather than tested separately.
The EMT provides basic life support. The AEMT adds advanced skills — IV and IO access, IV fluids, supraglottic (blind-insertion) airways, and a limited medication formulary such as epinephrine, naloxone, dextrose, and glucagon. The Paramedic adds endotracheal intubation, cardiac monitoring and 12-lead interpretation, manual defibrillation, and most IV medications.
An AEMT can start peripheral IV and intraosseous (IO) lines, give IV crystalloid fluids, insert supraglottic airways, and administer additional medications — including IV dextrose (D10/D50), glucagon, epinephrine for anaphylaxis, naloxone, and nebulized albuterol — per state protocol. An AEMT still cannot intubate, interpret cardiac rhythms, or manually defibrillate.
You must hold a current EMT certification (National Registry or state equivalent) and complete a state-approved AEMT education program, often accredited through CAAHEP/CoAEMSP, including its didactic, lab, and clinical/field competencies. The cognitive exam application fee is about $159 (a dated anchor — verify current pricing at nremt.org).
National Registry AEMT certification is valid for two years. You recertify through continuing education under the National Continued Competency Program (NCCP) model — a mix of national, local, and individual component hours — and by maintaining a current state EMS license, rather than retaking the cognitive exam each cycle.
Study by domain weight. Clinical Judgment (31–35%) and Medical/OB-GYN (25–29%) are over half the exam, so weight your time there, then Cardiology, Airway, and Trauma. Keep pediatric considerations in mind across every domain, and after each module drill the same content in our free AEMT practice questions and flashcards.
