**Question 1.** Which of the following physical signs is most specific for chronic hypoxemia?

A) Cyanosis

B) Clubbing

C) Tachypnea

D) Use of accessory muscles

**Answer:** B

**Explanation:** Digital clubbing results from long‑standing hypoxemia and is less acute than
cyanosis or tachypnea.



**Question 2.** In auscultation, a high‑pitched musical sound that varies with airway
obstruction is:

A) Fine crackles

B) Wheeze

C) Stridor

D) Pleural friction rub

**Answer:** B

**Explanation:** Wheezes are musical, high‑pitched sounds produced by narrowed airways and
change with airflow.



**Question 3.** The normal range for adult respiratory rate is:

A) 8‑12 breaths/min

B) 12‑20 breaths/min

C) 20‑30 breaths/min

D) 30‑40 breaths/min

**Answer:** B

**Explanation:** Healthy adults normally breathe 12‑20 times per minute at rest.



**Question 4.** An elevated hematocrit in a patient with COPD most likely reflects:

A) Acute blood loss

B) Polycythemia secondary to chronic hypoxia

C) Iron‑deficiency anemia

D) Hemolysis

**Answer:** B

**Explanation:** Chronic hypoxia stimulates erythropoietin, leading to secondary
polycythemia.



**Question 5.** On a chest X‑ray, a radiolucent line with absent lung markings peripherally
suggests:

A) Pleural effusion

B) Pneumothorax

C) Consolidation

D) Atelectasis

**Answer:** B

**Explanation:** Air in the pleural space creates a lucent line; lung markings are absent beyond
it.



**Question 6.** A patient’s ABG shows pH 7.30, PaCO₂ 55 mmHg, HCO₃⁻ 26 mEq/L. The primary
disorder is:

A) Metabolic acidosis

B) Metabolic alkalosis

C) Respiratory acidosis

D) Respiratory alkalosis

**Answer:** C

**Explanation:** Low pH with elevated PaCO₂ indicates a primary respiratory acidosis; HCO₃⁻ is
near normal (no compensation yet).



**Question 7.** In a partially compensated metabolic acidosis, the expected ABG pattern
includes:

A) Low pH, low PaCO₂, high HCO₃⁻

B) Low pH, high PaCO₂, low HCO₃⁻

C) Low pH, low PaCO₂, low HCO₃⁻

D) Normal pH, high PaCO₂, high HCO₃⁻

**Answer:** C

**Explanation:** Metabolic acidosis lowers HCO₃⁻; respiratory compensation lowers PaCO₂, but
pH remains low because compensation is incomplete.



**Question 8.** The P/F ratio of 150 mmHg indicates:

A) Mild ARDS

B) Moderate ARDS

C) Severe ARDS

D) Normal oxygenation

**Answer:** B

**Explanation:** According to the Berlin definition, a P/F ratio of 100‑200 mmHg denotes
moderate ARDS.

**Question 9.** Which ventilator setting primarily affects alveolar recruitment?

A) Tidal volume

B) Respiratory rate

C) PEEP

D) FiO₂

**Answer:** C

**Explanation:** Positive end‑expiratory pressure (PEEP) prevents alveolar collapse and
promotes recruitment.



**Question 10.** The appropriate cuff pressure for a standard endotracheal tube is:

A) 5‑10 cmH₂O

B) 10‑15 cmH₂O

C) 20‑30 cmH₂O

D) 35‑45 cmH₂O

**Answer:** C

**Explanation:** Maintaining cuff pressure between 20‑30 cmH₂O prevents tracheal mucosal
injury while avoiding leaks.



**Question 11.** When suctioning an intubated patient, the recommended pre‑oxygenation
time is:

A) 5 seconds

B) 10 seconds

C) 30 seconds
