1. Which of the following is the most common cause of upper airway obstruction?
A. the tongue
B. foreign bodies
C. trauma
D. laryngeal swelling
E. aspiration of blood or vomitus
Correct Answer: A. the tongue
Rationale: In an unconscious patient, the loss of muscle tone allows the tongue to
fall back against the posterior pharyngeal wall, causing the most common form of
upper airway obstruction. Foreign bodies, trauma, and swelling are less common
causes.
2. All of the following conditions may cause reduced inspiratory volumes EXCEPT:
A. pneumothorax
B. asthma
C. high inspired oxygen concentrations
D. respiratory muscle paralysis
E. emphysema
Correct Answer: C. high inspired oxygen concentrations
Rationale: High inspired oxygen concentrations do not reduce inspiratory
volumes; they increase oxygen delivery. Pneumothorax, asthma, muscle paralysis,
and emphysema all restrict or reduce the ability to inspire adequate volumes.
3. The normal respiratory rate for an adult at rest is:
A. 8 to 12
B. 12 to 20
1
,C. 18 to 24
D. 24 to 32
E. 40 to 60
Correct Answer: B. 12 to 20
Rationale: The normal resting respiratory rate for a healthy adult is 12-20 breaths
per minute. Rates below 12 indicate bradypnea, and rates above 20 indicate
tachypnea.
4. Which of the following is a breathing pattern associated with flail chest?
A. abdominal breathing
B. paradoxical breathing
C. diaphragmatic breathing
D. intercostal retraction
E. both A and C
Correct Answer: B. paradoxical breathing
Rationale: Flail chest results from multiple rib fractures causing a segment of the
chest wall to move independently. During inspiration, the flail segment moves
inward (paradoxical movement), and during expiration it moves outward,
reducing ventilatory efficiency.
5. It is unlikely that a patient will have significant hypoxia and not display
cyanosis.
A. True
B. False
Correct Answer: B. False
Rationale: Cyanosis is a late and unreliable sign of hypoxia. Patients can have
significant oxygen desaturation (SpO2 < 90%) without displaying visible cyanosis,
especially in anemia or poor peripheral perfusion.
6. Which modified form of respiration is designed to expand alveoli that may have
collapsed during periods of inactivity or rest?
A. coughing
B. sneezing
2
,C. hiccoughing
D. grunting
E. sighing
Correct Answer: E. sighing
Rationale: Sighing is a deep breath that occurs spontaneously to recruit collapsed
alveoli (atelectasis) and maintain lung compliance. It is a normal physiological
mechanism to prevent alveolar collapse.
7. The respiratory pattern that presents with deep and rapid respirations is:
A. apneustic respirations
B. Cheyne-Stokes respirations
C. Biot's respirations
D. central neurogenic hyperventilation
E. agonal respirations
Correct Answer: D. central neurogenic hyperventilation
Rationale: Central neurogenic hyperventilation is characterized by deep and rapid
respirations (tachypnea with large tidal volumes), often seen with brainstem
injury or increased intracranial pressure.
8. Stridor is most commonly associated with:
A. laryngeal constriction or edema
B. the tongue blocking the airway
C. narrowing of the bronchioles
D. fluids within the airway
E. foreign bodies in the lower airway
Correct Answer: A. laryngeal constriction or edema
Rationale: Stridor is a high-pitched, musical sound heard on inspiration, indicating
upper airway obstruction at the level of the larynx or trachea, often due to
edema, foreign body, or laryngospasm.
9. The feeling of flexibility or stiffness associated with the lungs and ventilation is:
A. back pressure
B. resiliency
3
, C. compliance
D. effusion
E. Hering-Breuer reflex
Correct Answer: C. compliance
Rationale: Lung compliance refers to the ease with which the lungs expand during
inspiration. High compliance (emphysema) means the lungs are overly flexible;
low compliance (fibrosis) means stiffness and difficulty expanding.
10. The absence of CO2 in exhaled air, as identified by the end-expiratory CO2
detector, suggests:
A. ventilation is not deep enough
B. ventilations are not occurring fast enough
C. the endotracheal tube may be in the esophagus
D. the oxygen percentage of inspired air is insufficient
E. all of the above
Correct Answer: C. the endotracheal tube may be in the esophagus
Rationale: End-tidal CO2 detection is the most reliable method to confirm
endotracheal tube placement. Absence of CO2 suggests esophageal intubation, as
the esophagus does not produce CO2 from gas exchange.
11. In the head-tilt/chin-lift maneuver, the fingers under the chin should apply a
firm pressure to ensure the jaw remains closed.
A. True
B. False
Correct Answer: B. False
Rationale: The fingers under the chin should lift the jaw upward to open the
airway, not press firmly to close the jaw. Pressing the jaw closed would obstruct
the airway rather than open it.
12. The intent behind employing Sellick's maneuver is to:
A. displace the diaphragm
B. increase venous return
C. prevent regurgitation
