2

A 25-year-old male patient presents with ingestion of antifreeze solution. His arterial blood gas analysis report is as follows: pH = 7.20 Anion gap = 15 PCO2 = 25 HCO3 = 10 What is the most likely diagnosis?

ANone of the options

BNormal anion gap metabolic acidosis

CHigh anion gap metabolic acidosis

DBoth

3

Renal tubular acidosis with ABG value pH = 7.24 PO2=80; PaCO2= 36 Na = 131; HCO3 = 14 Cl= 90; BE = -13 Glucose = 135 the above ABG picture suggests –

AMetabolic acidosis

BRespiratory alkalosis

CMetabolic alkalosis

DRespiratory acidosis
