A nurse is caring for a patient who is receiving gentamicin IV for treatment of endocarditis caused by gram-negative bacteria.
Which laboratory value should be monitored closely during gentamicin therapy?

Serum creatinine

Serum potassium

Serum calcium

Serum glucose.

Answer and Explanation

The Correct Answer is A

Gentamicin is an aminoglycoside antibiotic that can cause nephrotoxicity, which is damage to the kidneys. Serum creatinine is a measure of kidney function and should be monitored closely during gentamicin therapy. The normal range for serum creatinine is 0.6 to 1.2 mg/dL for men and 0.5 to 1.1 mg/dL for women.

Choice B is wrong because serum potassium is not affected by gentamicin.

The normal range for serum potassium is 3.5 to 5.0 mEq/L.

Choice C is wrong because serum calcium is not affected by gentamicin.

The normal range for serum calcium is 8.5 to 10.2 mg/dL.

Choice D is wrong because serum glucose is not affected by gentamicin.

The normal range for serum glucose is 70 to 110 mg/dL.
