The nurse is caring for a client who is receiving IV gentamicin for a gram-negative infection. Which of the following laboratory results would be of GREATest concern to the nurse?
Correct answer
A
Rationale
A creatinine of 2.5 mg/dL indicates renal impairment, a serious complication of gentamicin due to nephrotoxicity, requiring immediate evaluation. Options B, C, and D are normal: sodium 140 mEq/L, potassium 4.0 mEq/L, and hemoglobin 13 g/dL do not indicate complications.
