NREMT EMT Mock Examination – Comprehensive
Emergency Medical Technician Practice Questions
with Rationales
1. You arrive on the scene of a 65-year-old male patient who is unresponsive. As you begin
your primary assessment, you hear a gurgling sound during his inspirations. What is your
immediate priority?
A. Insert an oropharyngeal airway (OPA)
B. Begin positive pressure ventilations
C. Suction the airway for no more than 15 seconds
D. Apply high-flow oxygen via non-rebreather mask
Correct Answer: C
Explanation: The tested concept is airway clearance in the presence of liquid obstructions.
Suctioning is the priority because gurgling indicates fluid in the upper airway that must be
removed to prevent aspiration. Clinically, failure to clear the airway before providing
ventilations or oxygen can lead to fluid entering the lungs, causing pneumonia or
preventing effective gas exchange. A common mistake is attempting to insert an OPA before
suctioning, which may force fluids deeper into the trachea.
,2. An adult patient was pulled from a house fire. He has soot around his nose and mouth and
is complaining of a ‘tight’ throat. His respiratory rate is 28 breaths/min and labored. What is
the most appropriate next step?
A. Wait for ALS to arrive before administering oxygen
B. Perform a secondary assessment to look for other burns
C. Ask the patient to take a seat and provide room air
D. Provide high-flow oxygen via a non-rebreather mask and monitor for airway swelling
Correct Answer: D
Explanation: The tested concept is the management of potential inhalation injury. High-
flow oxygen is critical as soot and throat tightness suggest an impending airway
obstruction due to thermal or chemical edema. This action is clinically significant because
early intervention with oxygen can mitigate the effects of carbon monoxide poisoning often
associated with fires. Candidates often underestimate the severity of inhalation burns
because the patient is currently talking, but rapid deterioration is highly likely.
3. You are treating a 72-year-old female who is complaining of crushing chest pain and
shortness of breath. Her blood pressure is 88/54 mmHg. Which medication is contraindicated
for this patient?
A. Aspirin
B. Nitroglycerin
C. Oxygen
,D. Albuterol
Correct Answer: B
Explanation: The tested concept is the contraindication of nitroglycerin in the presence of
hypotension. Nitroglycerin is a vasodilator that can further drop a patient’s blood pressure,
potentially leading to inadequate coronary and cerebral perfusion in a patient already
showing signs of shock. Clinically, maintaining a systolic blood pressure of at least 90-100
mmHg is required before administering nitroglycerin. Candidates mistakenly administer
nitro based on the chest pain complaint without checking the blood pressure first.
4. After delivering a single shock from an AED to a 50-year-old male in cardiac arrest, the
device prompts ‘No shock advised.’ What should you do next?
A. Re-analyze the rhythm immediately
B. Check for a carotid pulse
C. Resume high-quality chest compressions immediately
D. Provide two rescue breaths
Correct Answer: C
Explanation: The tested concept is the standard AHA/ECC sequence for cardiac arrest
management. Resuming chest compressions immediately after a shock or ‘no shock’
prompt is vital to maintain coronary perfusion pressure. Clinically, minimizing
interruptions in CPR is one of the most significant factors in improving survival outcomes
, from sudden cardiac arrest. Candidates often waste critical time checking for a pulse when
the AED advises ‘no shock,’ which should only be done if the patient shows signs of life.
5. A 19-year-old male has been stabbed in the left chest. He is struggling to breathe, and you
hear air being drawn into the wound. What is your first treatment step?
A. Apply an occlusive dressing taped on three sides
B. Pack the wound with sterile gauze
C. Immediately cover the wound with your gloved hand
D. Perform a needle decompression
Correct Answer: C
Explanation: The tested concept is the immediate management of an open pneumothorax.
Covering the wound with a gloved hand provides an instant seal to prevent more air from
entering the pleural space while the partner prepares an occlusive dressing. This is
clinically significant because it stops the progression of a simple pneumothorax to a life-
threatening tension pneumothorax. A common error is looking for equipment before
sealing the hole, allowing the patient’s condition to deteriorate further.
6. A 24-year-old female is found unconscious in an alley. Her respirations are 4 breaths/min
and shallow, and her pupils are pinpoint. What is your priority intervention?
A. Assist ventilations with a bag-valve mask (BVM) and 100% oxygen
B. Administer intranasal Naloxone
C. Perform a rapid head-to-toe trauma assessment
