Which of the following condition is not associated with an increased anion gap?
Both proximal and distal A causes normal anion gap metabolic acidosis. Normal anion gap is 8 - 12 mEq/L. Conditions associated with increased anion gap acidosis are lactic acidosis, ketoacidosis, ingestion of toxins ( alcohol, ethylene glycol, methanol, isopropyl alcohol), acute and chronic renal failure.
Salicylate poisoning
Proximal A
Ethylene glycol poisoning
Lactic acidosis
