This ABG shows:Low pH (7.19): indicating acidosis.Low HCO3 (12 mEq/L): indicating a metabolic problem (consistent with Diamox causing bicarbonate loss).Low PaCO2 (29 mmHg): indicating respiratory compensation (hyperventilation to blow off CO2), which aligns with the observed deep and rapid respirations.Therefore, option A is the correct answer as it reflects metabolic acidosis with appropriate respiratory compensation, consistent with the patient's Diamox use and clinical presentation.
