Question

a nurse is caring for a client who has a new prescription for acyclovir to treat a herpes simplex infection. which of the following laboratory values should the nurse monitor for this client?

• prothrombin time
• hematocrit
• bun
• aspartate aminotransferase

Explanation:

Acyclovir is excreted by the kidneys, so monitoring renal function is crucial. Blood Urea Nitrogen (BUN) is a marker of renal function. Prothrombin time relates to coagulation, hematocrit to red blood cell volume, and aspartate aminotransferase to liver function—none are primary concerns for acyclovir monitoring like renal function (BUN) is.

Answer:

C. BUN
