Which of the following condition is the most common cause of increase
anion gap?
A.Metabolic alkalosis
B. Metabolic acidosis
Respiratory acidosis
Respiratory alkalosis -ANSWER-B. Metabolic acidosis
High anion gap metabolic acidosis is caused generally by the body
producing too much acid or not producing enough bicarbonate. This is
often due to an increase in lactic acid or ketoacids, or it may be a sign of
kidney failure. More rarely, high anion gap metabolic acidosis may be
caused by ingesting methanol or overdosing on aspirin.

A patient with walking pneumonia is being treated with penicillin. State one
possible condition why the patient is not recovering:
The organism produces beta lactamase
The organism has no cell wall
The organism has capsule
,The organism produces an enzyme that neutralizes the antibiotic -
