NREMT EMT-Basic Exam Domain Review: Airway, Cardiology, Trauma, Medical, and EMS Operations

NREMT EMT-Basic Exam: What to Expect

The NREMT cognitive exam for EMT-Basic uses a computerized adaptive testing (CAT) format that adjusts question difficulty based on your responses. The exam draws from five content domains: Airway, Respiration, and Ventilation; Cardiology and Resuscitation; Trauma; Medical and Obstetrics/Gynecology; and EMS Operations. Every question is scenario-based — you will never see a bare definition question. Instead, you will read a patient presentation and choose the best action or assessment finding. Your goal is to demonstrate entry-level competence, not expert mastery.

Domain 1: Airway, Respiration, and Ventilation

Airway management is the EMT's highest priority. Always open the airway before moving to breathing or circulation. Use a head-tilt chin-lift for medical patients with no suspected spinal injury; use a jaw thrust for trauma patients where a cervical spine injury is possible.

Assess breathing rate, depth, and quality. Adequate breathing means a normal rate for age, good chest rise, and clear bilateral breath sounds. Inadequate breathing — too slow, too fast, shallow, or labored — requires assisted ventilation with a bag-valve-mask (BVM) and supplemental oxygen. Maintain an oxygen saturation (SpO₂) target as directed by local protocol, but always act on the patient's clinical appearance first.

Airway adjuncts include the oropharyngeal airway (OPA) for unconscious patients with no gag reflex, and the nasopharyngeal airway (NPA) for patients who are responsive or have an intact gag reflex. Suction before inserting any adjunct if secretions are present. Limit suction to 15 seconds per attempt for adults.

Domain 2: Cardiology and Resuscitation

Cardiac arrest management follows the chain of survival. Begin high-quality CPR immediately — push hard (at least 2 inches depth in adults), push fast (100–120 compressions per minute), allow full chest recoil, and minimize interruptions. The compression-to-ventilation ratio is 30:2 for a single rescuer or two rescuers without an advanced airway in place.

Apply an AED as soon as it is available. Analyze the rhythm, clear all personnel before each shock, and resume CPR immediately after shock delivery without waiting to reassess a pulse. For pediatric patients, use a pediatric-capable AED or attenuator pads when available.

For non-arrest cardiac emergencies — chest pain, suspected acute MI — gather a SAMPLE history, give supplemental oxygen if SpO₂ is below protocol threshold, position the patient comfortably (usually sitting up), keep the patient calm, and transport promptly. Aspirin administration follows local protocol and medical direction.

Domain 3: Trauma

Trauma questions test your ability to prioritize life threats. Use the MARCH sequence as a mental framework: Massive hemorrhage, Airway, Respiration, Circulation, Hypothermia. For major external bleeding, direct pressure is always the first intervention. Apply a tourniquet to a limb when direct pressure fails to control life-threatening hemorrhage; note the time of application.

Shock (hypoperfusion) in trauma is most often hemorrhagic. Signs include altered mental status, pale/cool/moist skin, weak and rapid pulse, and hypotension (a late sign). Treatment is rapid transport, oxygen, keeping the patient warm, and following local protocol — the definitive treatment for hemorrhagic shock is surgical hemorrhage control at the hospital.

Head-to-toe assessment (detailed physical exam) is performed on significant trauma patients after the primary assessment is complete and life threats are managed. Maintain spinal motion restriction per your local protocol and medical director guidance.

Domain 4: Medical and Obstetrics/Gynecology

Medical scenarios require careful history-taking. Use SAMPLE (Signs/Symptoms, Allergies, Medications, Pertinent past history, Last oral intake, Events leading up) and OPQRST (Onset, Provocation, Quality, Radiation, Severity, Time) for every patient.

Altered mental status (AMS) has many causes — remember AEIOU-TIPS (Alcohol/Acidosis, Epilepsy, Insulin/hypoglycemia, Overdose, Uremia, Trauma, Infection, Psychiatric, Stroke/Shock). For any AMS patient, check blood glucose if a glucometer is available. Hypoglycemia is rapidly reversible; treat per protocol.

For respiratory emergencies, distinguish between obstructive causes (asthma, COPD) and cardiac causes (CHF/pulmonary edema). Asthma and COPD patients may benefit from assisted use of their prescribed bronchodilator inhaler with medical direction approval.

For obstetric emergencies, if delivery is imminent (crowning is visible, or the patient cannot resist the urge to push), prepare to deliver in the field. Control the head, check for a nuchal cord, support the body, keep the newborn warm, dry, and stimulate. Clamp and cut the cord per your protocols. The mother is also your patient — monitor for postpartum hemorrhage.

Domain 5: EMS Operations

EMS operations questions cover scene safety, mass-casualty incidents (MCI), lifting and moving, and documentation. Scene safety comes before patient care — every time. Body substance isolation (BSI) / standard precautions apply to every patient contact: gloves at minimum, and mask/eye protection when splash is possible.

At an MCI, the START triage system (Simple Triage and Rapid Treatment) classifies patients as Immediate (Red), Delayed (Yellow), Minor (Green), or Expectant/Deceased (Black) based on respirations, perfusion, and mental status. Your job in the first pass is to tag patients, not treat them — except to open an airway or control catastrophic bleeding.

Proper lifting mechanics protect both you and your patient. Use your legs, keep the load close to your body, and communicate clearly with your partner before every move. Know when to use an emergency move (immediate life threat in current position) versus a non-urgent move.

Safety Reminder

On both the exam and in the field: scene safety and BSI/standard precautions are always your first steps. Selecting a clinical intervention before establishing scene safety is always a wrong answer on the NREMT.
