Which of the following condition is the most common cause of
increase anion gap?
A.Metabolic alkalosis
B. Metabolic acidosis
Respiratory acidosis
Respiratory alkalosis
Ans: 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
Ans: B. The organism has no cell wall.
Feedback Pneumonia caused by Mycoplasma pneumoniae is
routinely treated with antibiotics, although the disease is
usually self-limiting. The disease is treated with macrolide,
tetracycline, or fluoroquinolone classes of antibiotics. All
mycoplasmas lack a cell wall and, therefore, all are inherently
resistant to beta-lactam antibiotics (e.g., penicillin).
What is the coefficient of variation if the mean is 90 and the standard
deviation is 5.48?
