Pass the NREMT Medical Technicians EMT Questions and answers with CertsForce

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:

The reassessment phase in the EMT patient assessment model starts with repeating the primary survey (also called the primary assessment), which includes:

Airway

Breathing

Circulation

Disability (mental status)

Exposure/environment

The purpose is to identify any changes or deterioration in the patient’s life-threatening conditions, especially in dynamic or unstable patients. Only after this do EMTs check vitals and reevaluate secondary complaints.

Comprehensive and Detailed Explanation From Exact Extract:

In patients with asthma experiencing respiratory failure, improper ventilation (especially excessive rates) can lead to air trapping and increased intrathoracic pressure, reducing venous return and worsening hypotension. The correct technique is to ventilate slowly to allow full exhalation — around 1 breath every 5–6 seconds for adults.

CPAP is contraindicated in unresponsive patients who cannot maintain their own airway. A non-rebreather mask would be insufficient for an unresponsive patient, and forceful ventilation risks barotrauma.

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.

This patient’s presentation is highly suspicious for acute coronary syndrome (ACS). NREMT education emphasizes that epigastric pain, especially in elderly patients, may represent myocardial ischemia. The lack of relief after three doses of nitroglycerin further increases concern for an evolving myocardial infarction.

Option A (Give aspirin) is correct because aspirin inhibits platelet aggregation and is a cornerstone of early ACS management. NREMT guidelines recommend administering aspirin as soon as possible unless contraindications exist.

Option B (Apply oxygen) is correct because the patient’s oxygen saturation is 92%, which is below normal. NREMT recommends supplemental oxygen for patients with suspected cardiac ischemia who are hypoxic or in respiratory distress.

Option C may provide comfort but does not address the underlying ischemia.

Option D is incorrect because the patient has already taken the maximum recommended prehospital doses of nitroglycerin.

Option E is outside the EMT scope of practice in many systems and is not a priority EMT intervention.

NREMT emphasizes early aspirin administration, oxygenation, continuous monitoring, and rapid transport for suspected ACS.

Return of spontaneous circulation (ROSC) indicates that the patient has regained a perfusing rhythm. If the patient is pushing away the BVM, this suggests improving mental status and spontaneous respirations.

Option D is correct because NREMT post-resuscitation care requires EMTs to reassess airway, breathing, and circulation, including confirming a pulse, and transition from assisted ventilations to supplemental oxygen if the patient is breathing adequately.

Options A and B are inappropriate because restraining a post-ROSC patient is rarely indicated and may worsen agitation.

Option C omits reassessment of circulation, which is critical after ROSC.

NREMT stresses frequent reassessment and supportive care following successful resuscitation.

Febrile seizures most commonly occur in children between 6 months and 5 years of age. NREMT pediatric education emphasizes that seizures in infants younger than 6 months are not considered simple febrile seizures and should raise immediate concern for serious central nervous system infection.

Option C is correct because this patient is only 2 months old, placing them outside the typical age range for febrile seizures. Additionally, the presence of a petechial rash, lethargy, hypotension, and fever strongly suggests meningitis or sepsis, both of which are life-threatening.

Option A is incorrect because fever alone does not confirm febrile seizure.

Option B is incorrect because lack of medical history does not exclude serious infection.

Option D is partially true but not the most accurate or distinguishing reason.

NREMT stresses early recognition of meningitis, rapid transport, and aggressive supportive care due to high mortality risk in infants.

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.

Comprehensive and Detailed Explanation (Based on NREMT standards):

This patient has signs of penetrating chest trauma, severe hypotension, tachycardia, and respiratory distress. A gurgling chest wound suggests an open pneumothorax, which can progress to tension pneumothorax.

Option C (Obstructive shock) is correct because air trapped in the chest can compress the heart and great vessels, preventing adequate cardiac output.

Option A is less likely because although blood loss may be present, the chest injury suggests impaired circulation due to pressure.

Option B involves pump failure, not trauma-related compression.

Option D involves abnormal vessel dilation, not mechanical obstruction.

NREMT emphasizes rapid recognition of obstructive shock and immediate intervention with occlusive dressings and rapid transport.

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.
