Section 1: Airway Management & Respiratory Emergencies
Q1: A 68-year-old male presents with acute respiratory distress. He is conscious, has an oxygen
saturation of 84% on room air, and exhibits accessory muscle use with audible wheezing. His respiratory
rate is 32/min. What is the priority intervention?
A. Immediate endotracheal intubation
B. High-flow oxygen via non-rebreather mask at 15 L/min
,C. [CORRECT] High-flow oxygen via non-rebreather mask at 15 L/min and prepare for CPAP if no
improvement
D. Insertion of an oropharyngeal airway
Correct Answer: C
Rationale: The patient is conscious with signs of severe respiratory distress but is still protecting his
airway. High-flow oxygen is the immediate priority. CPAP (Continuous Positive Airway Pressure) is
indicated for conscious patients with respiratory distress from conditions like COPD or pulmonary
edema, as it reduces work of breathing and improves oxygenation by recruiting alveoli and decreasing
preload.
Q2: During capnography monitoring of a mechanically ventilated patient, you observe an EtCO2 reading
of 28 mmHg with a normal waveform. What does this finding most likely indicate?
A. Hypoventilation
B. [CORRECT] Hyperventilation
C. Esophageal intubation
D. Complete airway obstruction
Correct Answer: B
Rationale: Normal EtCO2 is 35–45 mmHg. A reading of 28 mmHg is below normal, indicating
hyperventilation and decreased PaCO2. The normal waveform confirms proper endotracheal tube
placement; esophageal intubation would show minimal to no CO2 waveform, and complete obstruction
would produce a flatline waveform.
Q3: You are managing a 45-year-old trauma patient with a Glasgow Coma Scale (GCS) score of 7. He has
gurgling respirations and vomitus in his airway. What is the most appropriate immediate action?
A. Insert a nasopharyngeal airway
B. [CORRECT] Suction the airway and prepare for endotracheal intubation
C. Insert an oropharyngeal airway and administer high-flow oxygen
D. Position the patient in the recovery position
Correct Answer: B
Rationale: A GCS of 7 indicates the patient cannot protect his airway. Gurgling respirations with vomitus
present an immediate aspiration risk. The priority is suctioning to clear the airway, followed by definitive
airway management via endotracheal intubation, as this patient meets criteria for airway protection.
,Q4: A 55-year-old female with COPD presents with respiratory distress. Her SpO2 is 88% on 2 L/min
nasal cannula at home. She is alert, has a respiratory rate of 28/min, and diminished breath sounds
bilaterally. Which oxygen delivery device is most appropriate?
A. Non-rebreather mask at 15 L/min
B. [CORRECT] Nasal cannula titrated to maintain SpO2 88–92% or Venturi mask for precise FiO2 delivery
D. CPAP at 10 cm H2O without supplemental oxygen
C. Bag-valve-mask with 100% oxygen
Correct Answer: B
Rationale: Patients with COPD may have chronic CO2 retention and depend on hypoxic drive. Oxygen
should be titrated cautiously to maintain SpO2 between 88–92%. A Venturi mask provides precise FiO2
delivery, preventing excessive oxygen administration that could suppress respiratory drive and worsen
hypercapnia.
Q5: You have just intubated a 30-year-old male cardiac arrest patient. Which method provides the most
reliable confirmation of proper endotracheal tube placement?
A. Auscultation of breath sounds bilaterally
B. Visualization of chest rise
C. [CORRECT] Continuous waveform capnography showing sustained EtCO2 >10 mmHg with appropriate
waveform
D. Observation of condensation in the endotracheal tube
Correct Answer: C
Rationale: Continuous waveform capnography is the gold standard for confirming endotracheal tube
placement. A sustained EtCO2 reading greater than 10 mmHg with a normal rectangular waveform
confirms tracheal placement. While auscultation, chest rise, and condensation are supportive findings,
they are not definitive and can occur with esophageal intubation.
Q6: A 4-year-old child is in respiratory distress due to croup. He has stridor at rest, mild retractions, and
is alert. His SpO2 is 92% on room air. What is the most appropriate initial intervention?
A. Immediate endotracheal intubation
B. Racemic epinephrine via nebulizer and corticosteroids
C. [CORRECT] Humidified oxygen and nebulized epinephrine (racemic or L-epinephrine)
D. Needle cricothyrotomy
, Correct Answer: C
Rationale: This child has moderate croup (stridor at rest with mild retractions but alert). Humidified
oxygen reduces airway edema and soothes irritated mucosa. Nebulized epinephrine (racemic or L-
epinephrine) causes rapid vasoconstriction and decreased subglottic edema, providing temporary relief
while corticosteroids take effect. Intubation is reserved for severe croup with impending airway
obstruction.
Q7: During transport of an intubated patient, the capnography waveform suddenly becomes flatline.
The patient is connected to the ventilator. What is your first action?
A. Increase the respiratory rate
B. [CORRECT] Check for circuit disconnect, extubation, or cardiac arrest
C. Administer a fluid bolus
D. Increase the tidal volume
Correct Answer: B
Correct Answer: B
Rationale: A sudden flatline capnography waveform indicates no CO2 is being detected. The differential
diagnosis includes disconnection of the ventilator circuit, accidental extubation, or cardiac arrest (no
CO2 production). The immediate action is to assess for these causes, beginning with visual inspection of
the circuit and tube position.
Q8: A 72-year-old male with a history of CHF presents with acute pulmonary edema. He is sitting
upright, diaphoretic, with a respiratory rate of 36/min, SpO2 of 82%, and bilateral crackles. Blood
pressure is 190/110 mmHg. What is the most appropriate intervention?
A. Immediate endotracheal intubation
B. [CORRECT] High-flow oxygen, CPAP, and sublingual nitroglycerin
C. Needle decompression of the chest
D. Administration of albuterol nebulizer
Correct Answer: B
Rationale: This patient has acute cardiogenic pulmonary edema with hypertension. CPAP (Continuous
Positive Airway Pressure) is the priority intervention for conscious patients with pulmonary edema, as it
reduces preload and afterload, decreases work of breathing, and improves oxygenation. Sublingual
nitroglycerin reduces preload and afterload, further improving cardiac function. Intubation is reserved
for patients who fail CPAP or become obtunded.
