EMT Emergency Medical Technicians Exam Questions and Answers

Comprehensive and Detailed Explanation (Based on NREMT standards):

Upon arrival, EMTs must immediately perform a scene size-up, which focuses on safety and incident management rather than patient treatment.

Option A (Identifying hazards) is correct because recognizing dangers such as traffic, fire, violence, or hazardous materials is essential to prevent responder injury.

Option E (Requesting additional resources) is correct because early recognition of the need for more personnel, ALS support, fire services, or law enforcement improves patient outcomes and scene control.

Option B is incorrect because ruling out life threats occurs during the primary assessment, not immediately upon arrival.

Option C is incorrect because patient treatment must wait until scene safety is confirmed.

Option D is incorrect because PPE use is a personal responsibility, not a primary scene-arrival task.

NREMT stresses that effective EMS operations begin with safety, situational awareness, and resource management.

Comprehensive and Detailed Explanation From Exact Extract:

This is a classic presentation of hypovolemic shock due to traumatic blood loss (open femur fracture, pelvic instability). Indicators include:

Low BP (86/42) = hypotension

High pulse (P 136) = compensation

Mental status decline (responsive only to voice) = indicates decompensated shock

Obstructive and distributive shock are not applicable. Compensated shock would show normal BP and alert mental status.

Comprehensive and Detailed Explanation From Exact Extract:

Hepatitis A is transmitted primarily via the fecal-oral route, often through contaminated food or water. It leads to an acute liver infection, not a chronic condition. Unlike Hepatitis C, which has no vaccine, Hepatitis A has an effective vaccine and is preventable with proper hygiene and immunization.

Hepatitis B is spread through blood and sexual contact, not fecal-oral. Hepatitis E is also fecal-oral but is rare in the U.S. and doesn't have a widely used vaccine.

Comprehensive and Detailed Explanation (Based on NREMT standards):

The healthcare provider is ultimately responsible for maintaining certification, licensure, and continuing education requirements. While agencies, supervisors, and training officers may assist or provide opportunities, NREMT clearly states that responsibility rests with the individual EMT.

Option C is correct because failure to meet certification requirements can result in expiration or revocation regardless of employer involvement.

Options A, B, and D are incorrect because these roles may support education but are not legally responsible for an individual provider’s compliance.

NREMT emphasizes professional accountability as a core expectation of EMS practice.

Comprehensive and Detailed Explanation (Based on NREMT standards):

Hepatitis A is a viral liver infection transmitted primarily through the fecal-oral route, often due to contaminated food, water, or poor hand hygiene. NREMT education highlights hepatitis transmission routes as part of infection control and standard precautions.

Option A is correct because hepatitis A spreads when microscopic amounts of fecal matter are ingested, commonly in environments with inadequate sanitation.

Options B, C, and D are incorrect because these forms of hepatitis are transmitted primarily through blood and body fluids, such as needlestick injuries, sexual contact, or shared needles.

Understanding transmission routes allows EMTs to apply proper protective measures and reduce occupational exposure risks, a core component of NREMT infection-control training.

Comprehensive and Detailed Explanation From Exact Extract:

Under HIPAA (Health Insurance Portability and Accountability Act), only designated personnel are authorized to handle inquiries regarding a patient’s Protected Health Information (PHI). The Privacy Officer is responsible for enforcing compliance with privacy regulations and addressing PHI access requests.

Shift supervisors or hospitals do not have the legal authority to release PHI unless specifically designated.

Pursed-lip breathing is a classic compensatory mechanism seen in patients with emphysema, a form of chronic obstructive pulmonary disease (COPD). According to NREMT education, emphysema is characterized by destruction of the alveolar walls, which leads to loss of lung elasticity. This loss prevents the small airways from remaining open during exhalation.

Option A is correct because pursed-lip breathing creates positive pressure in the airways during exhalation. This pressure helps keep collapsed airways open longer, allowing trapped air to escape and improving ventilation. It also reduces the work of breathing and helps alleviate dyspnea.

Option B is incorrect because decreased hemoglobin affects oxygen-carrying capacity, not airway mechanics or breathing patterns.

Option C is more commonly associated with chronic bronchitis, not emphysema.

Option D is incorrect because diaphragmatic dysfunction is not the primary cause of pursed-lip breathing.

NREMT emphasizes recognizing compensatory breathing patterns in chronic lung disease to guide supportive care, including oxygen administration and positioning.

The foundation of effective multiple-casualty incident (MCI) management is the Incident Command System (ICS). NREMT teaches that ICS provides clear leadership, communication, accountability, and coordination of resources.

Option D is correct because ICS allows for scalable management, efficient delegation, and integration of multiple agencies.

Option B is important but is a component of ICS, not the core principle.

Option C is a tactical step that occurs within the command structure.

Option A misunderstands ICS, as command is established based on arrival, not rank alone.

NREMT stresses that without ICS, MCIs become chaotic and unsafe, regardless of clinical skill.

Comprehensive and Detailed Explanation From Exact Extract:

Use the Glasgow Coma Scale (GCS) to calculate:

Eye Opening (E): Opens to speech = 3

Verbal Response (V): Confused but appropriate words = 4

Motor Response (M): Obeys commands = 6Total = 3 + 4 + 6 = 13

However, the question states he opens eyes to voice, knows name (orientation to person), and follows commands — this would mean:

Eye = 3

Verbal = 5 (Oriented to person, but disoriented to place/time)

Motor = 6

Correct Total: 14

This patient is experiencing anaphylactic shock, evidenced by hypotension, respiratory distress, hypoxia, and altered mental status. After epinephrine administration, NREMT priorities focus on aggressive oxygenation and airway support.

Option D is correct because a non-rebreather mask at high flow delivers the highest concentration of oxygen to a spontaneously breathing patient and is indicated with SpO₂ of 86%.

Option C would be indicated only if respirations were inadequate or absent.

Option B is insufficient for severe hypoxia.

Option A delays definitive supportive care.

NREMT emphasizes epinephrine first, followed immediately by high-flow oxygen and rapid transport.

Comprehensive and Detailed Explanation From Exact Extract:

In any unresponsive patient, the first step is to assess and open the airway to determine patency and identify obstruction or inadequate breathing.

Gasping respirations (agonal) are not effective; they require BVM ventilation support. The airway must be open before checking for a pulse or performing auscultation. A secondary assessment is performed only after primary survey and stabilization.

Comprehensive and Detailed Explanation From Exact Extract:

The tripod position — sitting upright, leaning forward, supporting the upper body with arms on knees — is a classic sign of respiratory distress. This position:

Maximizes diaphragmatic movement

Engages accessory muscles of respiration

Improves air exchange in patients with obstructive airway diseases (e.g., COPD, asthma)

It is rarely used by patients with abdominal pain or seizures and is not associated with cardiac arrest (where unconsciousness is expected).

Comprehensive and Detailed Explanation From Exact Extract:

Perfusion refers to delivery of oxygen and nutrients to tissues. It depends on three essential components:

Patent airway: Ensures oxygen reaches lungs

Intact microcirculation: Capillary-level exchange must function

Sufficient blood volume: Maintains blood pressure and oxygen transport

Hypoxic drive relates to COPD physiology, not perfusion. High alveolar pressure (like from CPAP) may impede venous return, and a low ventilation-perfusion ratio means poor oxygenation efficiency, which negatively affects perfusion.

Comprehensive and Detailed Explanation From Exact Extract:

Mechanism of Injury (MOI) assessment is a cornerstone of trauma care. It helps providers determine:

Extent of injury: High-speed collisions, falls from height, or penetrating trauma suggest internal injuries even if external signs are limited.

Need for additional resources: MOI may indicate the necessity of ALS backup, air transport, or technical rescue.

MOI cannot determine a patient’s medical history or guarantee survival predictions. The destination facility depends on multiple factors including triage protocols, vital signs, and local trauma system regulations.

Comprehensive and Detailed Explanation From Exact Extract:

The patient is in hypoperfusion (shock) from blood loss. In shock states, tissues are deprived of oxygen, leading to anaerobic metabolism, which produces lactic acid as a byproduct. This causes metabolic acidosis, which is a critical sign of systemic oxygen debt.

Carbon dioxide rises with respiratory failure, but lactic acid is a more specific indicator of cellular hypoxia.

Comprehensive and Detailed Explanation From Exact Extract:

Hemoptysis (coughing up blood) in a physically active person, such as a mountain climber, strongly suggests a pulmonary embolism (PE), particularly due to:

Dehydration

Prolonged exertion or immobility

High altitude increasing clot risk

Symptoms may include:

Shortness of breath

Chest pain

Tachypnea

Hemoptysis

Pulmonary edema generally causes pink frothy sputum and is more associated with heart failure. Neoplasm (lung cancer) is possible but much less acute in onset. Spontaneous pneumothorax causes dyspnea and pleuritic chest pain but not typically hemoptysis.

Comprehensive and Detailed Explanation From Exact Extract:

Laundry detergent ingestion — especially in the case of liquid detergent pods — is associated with caustic airway and gastrointestinal injuries. The presence of crackles and drowsiness are signs of aspiration and possible respiratory failure. Vomiting increases the risk of aspiration pneumonitis, and esophageal perforation is a life-threatening complication from corrosive ingestion.

While seizure and hypoglycemia are possible complications of toxic ingestion, they are not as immediately linked to the detergent profile as airway injury and aspiration risk.

Comprehensive and Detailed Explanation (Based on NREMT standards):

Neurogenic shock results from damage to the spinal cord, most commonly at or above the thoracic level. NREMT education emphasizes that this injury disrupts the sympathetic nervous system, which normally maintains vascular tone.

Option C is correct because loss of sympathetic tone leads to widespread vasodilation, causing hypotension and often bradycardia, distinguishing neurogenic shock from other shock types.

Option A is incorrect because acetylcholine inhibition is not the mechanism.

Option B describes cardiogenic shock.

Option D describes septic (distributive) shock.

NREMT highlights that recognizing neurogenic shock is critical, as treatment priorities differ from hypovolemic shock.

Comprehensive and Detailed Explanation From Exact Extract:

An epidural hematoma classically presents with a “lucid interval” — a brief period of regained consciousness following head trauma, followed by rapid deterioration. This is due to arterial bleeding, often from the middle meningeal artery, leading to increasing intracranial pressure.

Signs include:

High blood pressure

Decreasing respiratory rate

Altered LOC or unresponsiveness

Subdural hemorrhages are slower venous bleeds, common in elderly patients. Subarachnoid hemorrhage often presents with "worst headache of life." Intracerebral bleeds are less commonly linked to lucid intervals.

Comprehensive and Detailed Explanation From Exact Extract:

Altered mental status, combined with pale, cool, and clammy skin, is strongly suggestive of hypoglycemia (low blood sugar). Hypoglycemia is especially dangerous in diabetics who take insulin or oral hypoglycemics. The body's adrenergic response causes the "cool and clammy" presentation.

Hyperglycemia typically presents with warm, dry skin and develops more slowly. EMTs should administer oral glucose if the patient can swallow.

Comprehensive and Detailed Explanation From Exact Extract:

To establish negligence, four legal elements must be proven:

Duty to act – a legal obligation to provide care.

Breach of duty – failing to meet the standard of care.

Damages – harm occurred.

Proximate causation – the breach directly caused the damage.

"Proximate causation" means the EMT’s action or inaction is closely linked to the harm suffered by the patient.

The EMS system is activated when an emergency is recognized by a bystander, patient, or first responder. NREMT describes EMS activation as a sequence that begins with recognizing an emergency and then accessing the system.

Option D (Recognition) is correct because without recognition, no call for help occurs.

Option C (Notification) follows recognition.

Option B (Dispatch) occurs after notification.

Option A (Response) is the physical movement of EMS resources after dispatch.

NREMT emphasizes public education on recognizing emergencies as a key component of effective EMS systems.

NREMT medication management standards require EMTs to ensure that all medications are stored properly and are safe for administration. The presence of ice crystals indicates that a medication has frozen, which can alter its chemical stability, concentration, and effectiveness.

Option C is correct because medications that have frozen must be discarded and replaced, even if they later thaw. Freezing can cause separation of active ingredients or damage to the medication vial or syringe.

Option A is insufficient because expiration status does not address medication integrity.

Option B is incorrect because frozen medications are unsafe and should not be reused.

Option D is dangerous and explicitly prohibited, as warming does not restore medication safety.

NREMT emphasizes strict medication safety checks to prevent patient harm and ensure effective treatment.

Comprehensive and Detailed Explanation (Based on NREMT standards):

In pediatric patients, NREMT guidelines require EMTs to check a pulse before initiating CPR when the patient is unresponsive and not breathing. For infants, the appropriate pulse check site is the brachial artery, assessed for no more than 10 seconds.

Option D is correct because determining whether a pulse is present guides whether rescue breathing or full CPR is required.

Option B is only appropriate if a pulse is present.

Option C is indicated only if no pulse is found or if the heart rate is below 60 with signs of poor perfusion.

Option A delays critical resuscitative care.

NREMT stresses strict adherence to pediatric resuscitation sequences to ensure appropriate and timely intervention.

Crowing, also known as stridor, is a high-pitched sound heard during inspiration and indicates upper airway obstruction, often caused by swelling, foreign body, or infection such as croup or epiglottitis.

Option D is correct.

Option A (Rhonchi) and B (Wheezing) are lower airway sounds.

Option C (Bubbling) suggests fluid in the airway, not obstruction.

NREMT emphasizes rapid recognition of stridor because upper airway obstruction can quickly become fatal.

NREMT stroke management focuses on rapid identification and time-sensitive intervention, particularly for patients who may be eligible for thrombolytic therapy or endovascular treatment.

Option D (Time of first signs or symptoms) is critical. This determines the patient’s eligibility for treatments such as tissue plasminogen activator (tPA), which must be administered within a defined time window.

Option C (Patient’s denial of a headache) is also important because sudden, severe headache suggests hemorrhagic stroke, whereas its absence may support ischemic stroke. This information helps guide diagnostic urgency and treatment planning.

Option A is not immediately relevant prehospital.

Option B is administrative, not emergent.

Option E does not impact acute stroke management.

NREMT stresses the importance of early notification, accurate time history, and focused neurological reporting to improve stroke outcomes.

NREMT guidelines emphasize that patient refusal is only valid if the patient has decision-making capacity. This patient has a severe headache with critically elevated blood pressure, which raises concern for conditions such as hypertensive emergency, intracranial hemorrhage, or stroke—all of which can impair cognition.

Option D is correct because the EMT must first determine whether the patient is alert, oriented, understands the risks, and can communicate a rational decision. Without capacity, a refusal is not legally or ethically valid.

Option A is incorrect because a refusal form should only be signed after capacity is confirmed.

Option B does not address the legal and ethical priority.

Option C is unnecessary unless the patient lacks capacity and poses a danger to themselves or others.

NREMT stresses that EMTs must protect patient autonomy while ensuring informed refusal, especially in high-risk presentations.

Comprehensive and Detailed Explanation From Exact Extract:

Hepatitis A virus is transmitted exclusively via the fecal-oral route. Ingesting contaminated food or water allows the virus to enter the digestive tract, infecting liver cells. It's often spread through poor hand hygiene or unsanitary food handling.

It is not bloodborne, unlike Hepatitis B and C. It is not commonly spread through saliva or urine.

The cerebrum is the largest and most developed part of the human brain and is responsible for higher cognitive functions. According to NREMT anatomy and physiology education, the cerebrum controls thinking, reasoning, memory, judgment, voluntary movement, and sensory interpretation.

Option B is correct because conscious thought, problem-solving, and decision-making all originate in the cerebrum.

Option A (Pons) helps regulate breathing and sleep cycles.

Option C (Brain stem) controls vital functions such as heart rate, breathing, and blood pressure.

Option D (Cerebellum) coordinates balance, posture, and fine motor movement.

Understanding brain function helps EMTs correlate neurological findings with possible injuries or medical conditions.

NREMT guidelines emphasize that EMTs must be able to rapidly release any restraints applied to a patient in the event of airway compromise, vomiting, cardiac arrest, or sudden deterioration.

Option B is correct because exchanging handcuffs for EMS-controlled restraints ensures patient safety while maintaining custody. The EMT having the key allows immediate access if emergency care is required.

Option A is unsafe because the EMT does not have control over the restraints, potentially delaying lifesaving interventions.

Option C is incorrect because patient safety standards must always be met.

Option D is incorrect because transport is necessary for evaluation and care.

NREMT stresses that custody never supersedes patient safety, and EMS must maintain control of patient restraints during transport.

Comprehensive and Detailed Explanation From Exact Extract:

Agonal respirations are not effective breathing and can mimic gasping or snorting. They often occur in cardiac arrest. However, before initiating chest compressions, the EMT must confirm pulselessness by checking a carotid pulse for no more than 10 seconds (AHA 2020 BLS Guidelines).

Only after pulse confirmation (or absence) should compressions begin. Suctioning or ventilating is premature unless a pulse is found.

This pediatric presentation—fever, sore throat, and drooling—is highly concerning for acute epiglottitis, a life-threatening airway emergency emphasized in NREMT airway education. Epiglottitis causes rapid swelling of the epiglottis and surrounding tissues, which can lead to sudden and complete airway obstruction, especially in young children.

Option D is correct because the EMT should minimize agitation and transport the child in a position of comfort, typically sitting upright. NREMT guidelines stress that children with suspected epiglottitis should be kept calm, allowed to assume their preferred position, and transported rapidly without unnecessary interventions that could provoke airway spasm.

Option A is incorrect because finger sweeps are contraindicated unless a solid foreign body is clearly visible. Performing a finger sweep may worsen obstruction or trigger complete airway closure.

Option B is incorrect because positive-pressure ventilation with a BVM can increase agitation and is not indicated unless the patient is in respiratory failure. Oxygen may be offered gently, but forcing a BVM is dangerous.

Option C is incorrect because visual inspection of the airway using a tongue depressor can precipitate sudden airway obstruction and is specifically contraindicated by NREMT teaching.

The priority per NREMT is airway preservation through calm handling, rapid transport, and avoidance of invasive airway maneuvers.

Comprehensive and Detailed Explanation From Exact Extract:

The first step in hemorrhage control for external bleeding is always direct pressure using gloved hands or dressing. Only if this fails or the bleeding is severe and life-threatening (especially from extremities) should a tourniquet be applied.

Assessing the airway is critical in overall trauma care but not the first priority in isolated extremity hemorrhage. Severity assessment is secondary to bleeding control.

Comprehensive and Detailed Explanation From Exact Extract:

Missing dialysis leads to fluid overload, causing:

Pulmonary edema, evident by crackles on auscultation

Dyspnea and chest discomfort

Bradycardia is less likely; patients more often present with tachycardia due to volume stress. Fever would suggest infection (not stated here), and hypotension can occur later, but hypertension is more common in early fluid overload.
