Practice Questions with Answers & Detailed
Rationales – Airway Management, Cardiology,
Resuscitation, Trauma, Medical Emergencies,
Operations & Pharmacology
INTRODUCTION
The questions are organized across four core domains: Domain 1 – Airway
Management and Respiration (37 questions); Domain 2 – Cardiology and
Resuscitation (37 questions); Domain 3 – Trauma and Medical Emergencies (37
questions); and Domain 4 – Operations and Pharmacology (37 questions). Each
question is accompanied by the correct answer and a detailed rationale grounded in
foundational emergency medical services methodology, including principles drawn
from the official NREMT AEMT standards and established textbooks such as
Emergency Care and Transportation of the Sick and Injured (AAOS). The content
emphasizes rapid assessment, evidence-based prehospital interventions, and safe
pharmacologic management in the out-of-hospital environment.
Domain 1: Airway Management and Respiration
Question 1. The most reliable method to confirm correct endotracheal tube
placement in the prehospital setting is:
A. Chest rise alone
B. End-tidal CO2 detection (waveform capnography preferred) plus clinical
assessment
C. Auscultation of the epigastrium only
D. Tube depth measurement exclusively
Correct Answer: B
Rationale: Continuous waveform capnography is the gold standard for confirming
and monitoring ET tube placement. Clinical signs support but do not replace
objective CO2 detection.
,Question 2. A client with severe respiratory distress has a respiratory rate of
8/min and shallow tidal volumes. The priority intervention is:
A. Nasal cannula at 2 L/min
B. Encouraging the client to breathe faster without assistance
C. Assisted ventilation with a bag-valve-mask and high-flow oxygen
D. Immediate surgical airway without attempting BVM
Correct Answer: C
Rationale: Inadequate minute ventilation requires immediate positive-pressure
support. BVM ventilation with oxygen is the first-line intervention while preparing
advanced airway options.
Question 3. Which oxygen delivery device delivers the highest concentration
of oxygen to a spontaneously breathing client?
A. Nasal cannula at 6 L/min
B. Simple face mask at 6 L/min
C. Venturi mask at 28%
D. Non-rebreather mask with reservoir and adequate flow
Correct Answer: D
Rationale: A properly fitted non-rebreather mask can deliver FiO2 approaching
0.90–1.0 when flow is sufficient to keep the reservoir inflated.
Question 4. The correct sequence for suctioning an adult client with an
advanced airway is:
A. Suction continuously for 30 seconds while inserting
B. Pre-oxygenate, insert catheter without suction, apply suction while
withdrawing for no more than 10–15 seconds
C. Insert the catheter and suction for 20 seconds, then withdraw
D. Suction only after removing the advanced airway
Correct Answer: B
Rationale: Suctioning should be limited to 10–15 seconds to prevent hypoxia. Pre-
oxygenation and inserting the catheter without suction prevent mucosal trauma
and hypoxia.
Question 5. A 65-year-old client with COPD has an SpO2 of 88% on room air.
What is the appropriate target oxygen saturation range for this client?
A. 94–99%
B. 88–92%
,C. 95–100%
D. 80–85%
Correct Answer: B
Rationale: For clients with COPD and chronic CO2 retention, the target SpO2 is
88–92% to avoid suppressing the hypoxic drive and causing hypercapnia.
Question 6. Which of the following is a contraindication for the use of a
supraglottic airway (SGA) device?
A. Cardiac arrest
B. Gag reflex present
C. Unresponsive client
D. Respiratory failure
Correct Answer: B
Rationale: SGAs are contraindicated in clients with an intact gag reflex, as
insertion may trigger vomiting, laryngospasm, or aspiration. They are designed for
unresponsive clients without a gag reflex.
Question 7. What is the primary purpose of a nasopharyngeal airway (NPA)?
A. To provide a definitive airway
B. To maintain patency of the upper airway in an unresponsive client with an
intact gag reflex
C. To suction the lower airway
D. To deliver positive-pressure ventilation
Correct Answer: B
Rationale: An NPA is used to maintain upper airway patency in unresponsive
clients who have an intact gag reflex or who cannot tolerate an oropharyngeal
airway (OPA).
Question 8. A client is experiencing an acute asthma exacerbation. Which
medication is the first-line treatment?
A. Albuterol via nebulizer
B. Epinephrine 1:1,000 IM
C. Nitroglycerin SL
D. Aspirin 324 mg chewed
Correct Answer: A
Rationale: Albuterol is a short-acting beta-2 agonist (SABA) that provides rapid
bronchodilation and is the first-line treatment for acute asthma exacerbations.
, Question 9. What is the recommended rate of assisted ventilations for an adult
in cardiac arrest with an advanced airway in place?
A. 2 breaths every 30 compressions
B. 1 breath every 6 seconds (10 breaths/min)
C. 1 breath every 10 seconds (6 breaths/min)
D. 2 breaths every 10 seconds (12 breaths/min)
Correct Answer: B
Rationale: Once an advanced airway is placed during adult CPR, continuous
compressions are performed without pausing for ventilations, and the ventilation
rate is 1 breath every 6 seconds (10 breaths/min).
Question 10. A client presents with stridor, drooling, and severe respiratory
distress. Which condition should the AEMT suspect?
A. Asthma
B. Epiglottitis
C. COPD
D. Pulmonary edema
Correct Answer: B
Rationale: Epiglottitis is a life-threatening condition characterized by stridor,
drooling, dysphagia, and severe respiratory distress. Airway management must be
handled with extreme caution to avoid triggering complete obstruction.
Question 11. What is the primary function of surfactant in the alveoli?
A. To increase surface tension
B. To decrease surface tension and prevent alveolar collapse
C. To increase mucus production
D. To stimulate the cough reflex
Correct Answer: B
Rationale: Surfactant reduces surface tension in the alveoli, preventing them from
collapsing during expiration. A lack of surfactant leads to atelectasis and
respiratory distress.
Question 12. Which of the following findings indicates inadequate ventilation
in a client receiving BVM ventilations?
A. Chest rise and fall
B. Absent or diminished breath sounds over the epigastrium
