1. Which structure is primarily responsible for preventing food from entering the
trachea during swallowing?
A. Uvula
B. Epiglottis
C. Thyroid cartilage
D. Soft palate
Correct Answer: B. Epiglottis
Rationale: The epiglottis folds over the laryngeal opening during swallowing,
protecting the lower airway from aspiration. The uvula and soft palate help
direct food away from the nasal cavity but do not guard the trachea.
2. What is the primary muscle of quiet inspiration?
A. External intercostals
B. Abdominal muscles
C. Diaphragm
,D. Internal intercostals
Correct Answer: C. Diaphragm
Rationale: The diaphragm is the main muscle used during normal, quiet
inspiration, contributing approximately 70% of tidal volume. Accessory
muscles are recruited during labored breathing.
3. Where does most gas exchange occur in the lungs?
A. Bronchi
B. Trachea
C. Alveoli
D. Pleura
Correct Answer: C. Alveoli
Rationale: The alveoli provide a thin, large surface area (approximately 70
m²) for diffusion of oxygen and carbon dioxide. The conducting airways do
not participate in gas exchange.
4. Which gas normally moves from the alveoli into pulmonary capillary blood?
A. Nitrogen
B. Oxygen
C. Carbon dioxide
D. Helium
,Correct Answer: B. Oxygen
Rationale: Oxygen diffuses from the alveoli, where its partial pressure is
higher, into the pulmonary capillary blood. Carbon dioxide moves in the
opposite direction.
5. Which value represents a normal adult respiratory rate at rest?
A. 4–8 breaths/min
B. 8–10 breaths/min
C. 12–20 breaths/min
D. 20–30 breaths/min
Correct Answer: C. 12–20 breaths/min
Rationale: A normal adult respiratory rate at rest is 12–20 breaths per
minute. Rates outside this range may indicate respiratory distress or
metabolic abnormalities.
6. What is the normal resting heart rate for an adult?
A. 40–60 bpm
B. 60–100 bpm
C. 100–120 bpm
D. 120–140 bpm
, Correct Answer: B. 60–100 bpm
Rationale: The normal adult heart rate is 60–100 beats per minute.
Tachycardia (above 100) may result from hypoxemia, anxiety, fever, or pain.
7. Rapid assessment of oxygenation is best assessed by which method?
A. Arterial blood gas
B. Pulse oximetry
C. Capnography
D. Chest radiograph
Correct Answer: B. Pulse oximetry
Rationale: Pulse oximetry provides continuous, non-invasive, and rapid
estimation of arterial oxygen saturation (SpO₂). It is the quickest bedside
method for assessing oxygenation status.
8. What diagnostic test is best when attempting to assess a patient's airway at the
bedside?
A. Chest X-ray
B. Auscultation
C. Pulmonary function test
D. Bronchoscopy
Correct Answer: B. Auscultation
