What is the most likely diagnosis based on ABG results of pH 7.30, PaCO₂ 50 mmHg, HCO₃⁻ 24 mEq/L?
Show answer and explanation
Correct answer: c. Respiratory acidosis
The pH is low (<7.35 = acidosis) and PaCO₂ is elevated while HCO₃⁻ is near normal, indicating a respiratory cause (respiratory acidosis).
