Electrolyte abnormality following Amphotericin B treatment – MCQ

Amphotericin B treatment mandates the monitoring of which of the following electrolytes:
A. Na+
B. Ca2+
C. K+
D. Mg2+

Correct answer : C. K+

Both potassium and magnesium are lost in urine during treatment with amphotericin B. Hence both electrolytes should be monitored. But monitoring potassium levels are more important as hypokalemia can cause cardiotoxicity.
