300 Randomized Multiple-Choice Questions with Answers and Summarized Rationales
Section I: Patient Data Evaluation and Recommendations (Questions 1–108)
ABG Interpretation and Acid-Base Balance (Questions 1–25)
1. A patient's ABG on room air shows pH 7.34, PaCO₂ 55 mm Hg, PaO₂ 70 mm Hg, HCO₃⁻ 30


mEq/L. This represents:


A) Acute respiratory acidosis without compensation


B) Chronic respiratory acidosis with partial compensation


C) Metabolic alkalosis with respiratory compensation


D) Acute respiratory alkalosis


Answer: B — Elevated CO₂ with elevated HCO₃⁻ and near-normal pH indicates chronic retention


with renal compensation

2. A diabetic patient enters the ED breathing deeply at a rate of 32/min. This breathing


pattern is:


A) Cheyne-Stokes respiration


B) Kussmaul respiration


C) Biot's respiration


D) Apneustic breathing


Answer: B — Kussmaul respirations are deep and rapid, compensating for metabolic acidemia


by removing CO₂


3. Which ABG finding is most consistent with acute respiratory alkalosis?


A) pH 7.52, PaCO₂ 30 mmHg, HCO₃⁻ 24 mEq/L


B) pH 7.30, PaCO₂ 50 mmHg, HCO₃⁻ 26 mEq/L


C) pH 7.38, PaCO₂ 45 mmHg, HCO₃⁻ 28 mEq/L


D) pH 7.48, PaCO₂ 40 mmHg, HCO₃⁻ 32 mEq/L


Answer: A — Elevated pH, low CO₂, and normal HCO₃⁻ indicate acute hyperventilation


4. A COPD patient on 2 L/min nasal cannula has ABG: pH 7.38, PaCO₂ 55 mmHg, HCO₃⁻ 32


mEq/L, PaO₂ 68 mmHg. This represents:


A) Acute respiratory acidosis

B) Compensated metabolic alkalosis


C) Chronic respiratory acidosis with adequate compensation


D) Mixed respiratory and metabolic acidosis


Answer: C — Normal pH with elevated CO₂ and elevated HCO₃⁻ indicates fully compensated


chronic respiratory acidosis


5. Which set of ABG measurements indicates compensated respiratory acidosis?


A) pH 7.26, PCO₂ 60, HCO₃⁻ 26


B) pH 7.42, PCO₂ 39, HCO₃⁻ 22


C) pH 7.25, PCO₂ 61, HCO₃⁻ 26


D) pH 7.37, PCO₂ 58, HCO₃⁻ 31


Answer: D — Normal pH with elevated CO₂ and elevated HCO₃⁻ indicates full compensation


6. The normal range for anion gap is:


A) 2–6 mEq/L


B) 8–16 mEq/L


C) 20–28 mEq/L


D) 30–40 mEq/L


Answer: B — Normal anion gap is 8–16 mEq/L

7. Which ABG result indicates fully compensated respiratory acidosis?


A) pH 7.28, PaCO₂ 60, HCO₃⁻ 26


B) pH 7.36, PaCO₂ 55, HCO₃⁻ 30


C) pH 7.50, PaCO₂ 30, HCO₃⁻ 24


D) pH 7.30, PaCO₂ 50, HCO₃⁻ 24


Answer: B — pH in normal range with elevated CO₂ and elevated HCO₃⁻ indicates full


compensation


8. A patient with myasthenia gravis is admitted with acute respiratory failure. The most likely


ABG finding is:


A) Respiratory alkalosis with hypoxemia


B) Respiratory acidosis with hypoxemia


C) Metabolic acidosis with hyperoxia


D) Metabolic alkalosis with hypocapnia


Answer: B — Neuromuscular weakness causes hypoventilation, leading to CO₂ retention


(respiratory acidosis) and hypoxemia


9. A patient's ABG shows pH 7.25, PaCO₂ 30 mmHg, HCO₃⁻ 15 mEq/L. This represents:


A) Respiratory alkalosis
