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 primarily eliminated by the kidneys, so renal function must be monitored to prevent toxicity. BUN (Blood Urea Nitrogen) is a key lab value that reflects renal function. The other options monitor clotting (prothrombin time), red blood cell volume (hematocrit), and liver function (aspartate aminotransferase), which are not the primary concerns for acyclovir therapy.

Answer:

C. BUN
