, SECTION 1: PATIENT DATA EVALUATION & ASSESSMENT
Q1.
A 68-year-old patient with known COPD is admitted with increased dyspnea. Arterial blood gas on room air shows pH 7.32,
PaCO2 58 mm Hg, PaO2 52 mm Hg, HCO3 29 mEq/L. The respiratory therapist is asked to interpret the acid-base status and
recommend the most appropriate next diagnostic step.
A. Acute respiratory acidosis; recommend immediate intubation.
B. Chronic respiratory acidosis with hypoxemia; recommend oxygen titration and further evaluation of ventilation needs.
C. Metabolic alkalosis; recommend acetazolamide.
D. Normal acid-base balance; no intervention required.
Correct Answer: B
Rationale: Elevated PaCO2 with near-normal pH and elevated HCO3 indicates chronic (compensated) respiratory acidosis. Concurrent
hypoxemia requires controlled oxygen therapy and assessment of whether noninvasive or invasive ventilatory support is needed.
Q2.
During a physical assessment of a postoperative patient, the therapist notes decreased breath sounds on the left, tracheal
deviation toward the left, and dullness to percussion over the left lower lung field. Which condition is most consistent with these
findings?
A. Right-sided tension pneumothorax.
B. Left-sided pleural effusion or atelectasis.
C. Bilateral pneumonia.
D. Pulmonary embolism without radiographic change.
Correct Answer: B
Rationale: Tracheal deviation toward the affected side, decreased breath sounds, and dullness are classic for volume loss (atelectasis) or fluid
accumulation (pleural effusion) on the left. Tension pneumothorax would deviate the trachea away from the affected side and produce
hyperresonance.
Q3.
A patient with suspected restrictive lung disease undergoes spirometry. Results show FVC 55% predicted, FEV1 58%
predicted, and FEV1/FVC ratio 92%. What is the most accurate interpretation?
A. Severe obstructive pattern.
B. Restrictive pattern consistent with reduced lung volumes.
C. Mixed obstructive-restrictive pattern.
D. Normal spirometry with poor patient effort.
Correct Answer: B
Rationale: Reduced FVC and FEV1 with a normal or elevated FEV1/FVC ratio is the spirometric signature of restriction. Confirmation ideally
includes total lung capacity measurement, but the pattern itself is consistent with restrictive disease.
Q4.
A 45-year-old trauma patient arrives with a chest tube in place. Continuous bubbling is observed in the water-seal chamber and
the suction control chamber is set to −20 cm H2O. The therapist notes the bubbling increases with patient coughing. What does
this finding most likely indicate?
A. A persistent air leak from the lung or a system leak that requires systematic checking.
B. Normal function of the suction control chamber only.
C. Complete resolution of the pneumothorax.
D. Need to increase suction to −40 cm H2O immediately.
Correct Answer: A
Rationale: Continuous bubbling in the water-seal chamber indicates an air leak. Increased bubbling with coughing suggests the leak originates
from the lung; systematic inspection of tubing connections is still required to rule out an external system leak.
