Question 1 of 5
A male client with a massive pulmonary embolus is tachycardic, hypotensive, and has audible bilateral pulmonary crackles. His arterial blood gas (ABG) results are: pH 7.0: PaCO₂ 66 mm Hg; HCO3- 24 mEq/L (24 mmol/L); PaO₂ 60 mm Hg. Based on these findings, this client is at greatest risk for which pathophysiological condition?
Correct Answer: C
Rationale: ABG results (pH 7.0, PaCO₂ 66 mmHg, PaO₂ 60 mmHg) indicate respiratory acidosis and hypoxemia, signaling respiratory failure (
C) due to impaired gas exchange from the embolus. Embolic migration (
A) is a risk, not a condition. Atelectasis (
B) is secondary. Infarction (
D) is possible but less immediate.
