A nurse is caring for a client receiving an intermittent IV bolus of gentamicin twice daily. Which of the following laboratory values should the nurse monitor while the client is receiving this medication? (Select all that apply.)

Choice A rationale Monitoring glucose levels is not typically necessary for patients receiving gentamicin, as it does not significantly affect glucose metabolism. Choice B rationale Prothrombin time is not commonly affected by gentamicin, so routine monitoring is not required. Choice C rationale Serum creatinine levels should be monitored to assess kidney function, as gentamicin can cause nephrotoxicity. Choice D rationale Cardiac enzymes are not typically affected by gentamicin, so routine monitoring is not necessary. Choice E rationale Monitoring WBC count is important to detect any signs of infection or bone marrow suppression, which can occur with gentamicin use.
