Yield Questions, In-Depth Rationales,
and Clinical Reasoning Strategies to
Pass the Cognitive Exam on Your First
Attempt
1. A 45-year-old male is found unresponsive. His respirations are 8 per
minute and shallow. Which is the MOST appropriate initial action?
Answer: Assist ventilations with a bag-valve-mask (BVM) and 100%
oxygen.
Rationale: The patient has a respiratory rate of 8 (bradypnea) with
shallow breathing, indicating inadequate ventilation. The priority is to
support breathing with BVM ventilation.
2. Which of the following is a reliable sign of a patent airway in an
unresponsive patient?
Answer: Visible chest rise and fall with assisted ventilations.
Rationale: Chest rise is the most direct and reliable indicator that air is
entering the lungs and the airway is open. Other sounds like gurgling
or snoring indicate airway obstruction.
,3. A patient with a history of COPD is in respiratory distress. You are
administering oxygen. What is the PRIMARY concern regarding
oxygen delivery in this patient?
Answer: Depression of the hypoxic drive, leading to apnea.
Rationale: In some chronic COPD patients, the primary stimulus to
breathe is low oxygen levels (hypoxic drive). Administering high-flow
oxygen can eliminate this drive, causing respiratory depression.
4. What is the primary purpose of the "head-tilt, chin-lift" maneuver?
Answer: To open the airway by lifting the tongue away from the
posterior pharynx.
Rationale: The most common cause of airway obstruction in an
unresponsive patient is the tongue falling back and occluding the
pharynx. The head-tilt, chin-lift lifts the tongue forward.
5. You are assessing an adult patient who is awake but choking. He is
able to speak in a weak, hoarse voice. What is the appropriate
intervention?
Answer: Encourage him to cough forcefully.
Rationale: A patient who can speak or cough has a partial airway
obstruction. The body's natural defense is the cough reflex, so you
should encourage this. Do not perform abdominal thrusts on a patient
with an effective cough.
6. A 6-month-old infant is in severe respiratory distress with stridor
and a barking cough. What is the most likely cause?
Answer: Croup (Laryngotracheobronchitis).
Rationale: Croup is a viral infection causing inflammation of the upper
airway, particularly the subglottic area. It is characterized by a "seal-
, like" barking cough and stridor, most common in children aged 6
months to 3 years.
7. When assessing a patient with suspected anaphylaxis, what is the
FIRST medication you should consider administering?
Answer: Epinephrine.
Rationale: Epinephrine is the drug of choice for anaphylaxis. It reverses
bronchoconstriction and vasodilation, addressing the life-threatening
airway and circulatory compromise.
8. A patient is experiencing a severe asthma attack. Which finding is a
sign of an impending respiratory failure?
Answer: Diminished or absent breath sounds.
Rationale: As an asthma attack worsens, air movement becomes so
poor that breath sounds become faint or absent. This "silent chest" is
a critical sign that the patient is tiring and respiratory failure is
imminent, requiring immediate advanced intervention.
9. In a patient with a pneumothorax, breath sounds on the affected
side will most likely be:
Answer: Diminished or absent.
Rationale: Air in the pleural space prevents the lung from expanding,
thus air cannot move in and out of the lung on that side, resulting in
decreased or absent breath sounds.
10. What is the appropriate oxygen flow rate for a non-rebreather
mask?
Answer: 10-15 liters per minute.
, Rationale: A non-rebreather mask requires a high flow rate to keep
the reservoir bag inflated and deliver a high concentration of oxygen
(up to 90-95%). Flow rates less than this will cause the bag to collapse
and the patient to rebreathe their own CO2.
11. Which of the following is a contraindication for the use of an
oropharyngeal airway (OPA)?
Answer: A conscious patient with a gag reflex.
Rationale: An OPA is a rigid device that can stimulate the gag reflex,
leading to vomiting and aspiration. It should only be used on
unresponsive patients without a gag reflex.
12. What is the main cause of cardiac arrest in adult patients?
Answer: Ventricular Fibrillation (V-Fib).
Rationale: V-Fib is a chaotic, disorganized rhythm that results in no
cardiac output. It is the most common initial rhythm in adult sudden
cardiac arrest and is a shockable rhythm.
13. You are performing CPR on an adult. What is the correct ratio of
compressions to ventilations for a single rescuer?
Answer: 30:2.
Rationale: For a single rescuer providing CPR to an adult, the
compression-to-ventilation ratio is 30 compressions to 2 ventilations.
This is to maximize the number of compressions delivered, as they are
most critical for perfusion.
14. What is the recommended compression depth for an adult during
CPR?
Answer: At least 2 inches (5 cm), but not exceeding 2.4 inches (6 cm).
