Answer: A

Explanation:

(A) A common side effect of gentamicin is nephrotoxicity. The serum laboratory test that best reflects kidney function is serum creatinine.

(B) Serum sodium has no relationship to gentamicin.

(C) Serum calcium has no relationship to gentamicin.

(D) Serum potassium has no relationship to gentamicin. If a client has impaired renal function secondary to gentamicin administration, he or she may also have hyperkalemia as a secondary disorder.
