Answer

Brief Explanations:

  1. First, identify normal ABG ranges: pH 7.35-7.45, PaCO₂ 35-45 mmHg, HCO₃⁻ 22-26 mEq/L.
  2. The pH of 7.49 is above normal, indicating alkalosis.
  3. PaCO₂ (39 mmHg) is within normal range, ruling out respiratory causes.
  4. HCO₃⁻ (35 mEq/L) is above normal, which is the defining marker of metabolic alkalosis.

Answer:

Metabolic alkalosis
