Simulated
The nurse cares for a client receiving mechanical ventilation and reviews the client's most recent arterial blood gas (ABG). The nurse communicates the result with the primary healthcare provider (PHCP) and should recommend a prescription for which medication? Laboratory: pH 7.33 [7.35-7.45], PaCO2 53 mm Hg [35-45 mm Hg], HCO3 24 mEq/L [22-28 mEq/L], PaO2 89 mm Hg [80-100 mm Hg]
Correct answer
C
Rationale
The ABG shows respiratory acidosis (pH 7.33, PaCO2 53 mm Hg) due to hypoventilation. Theophylline (C) improves respiratory drive and ventilation. Pancuronium (A) and midazolam (B) suppress ventilation, worsening acidosis. Famotidine (D) addresses gastric issues, not respiratory.
