A nurse is assessing a client who is taking gentamicin. For which of the following findings should the nurse withhold the medication?

A. Tinnitus: Gentamicin is an aminoglycoside antibiotic with ototoxic potential. The presence of tinnitus may indicate early ototoxicity, and withholding the medication is necessary to prevent further auditory damage. B. Altered taste sensation: Changes in taste are generally mild and not a life-threatening side effect. They do not require withholding the medication but should be documented and monitored. C. Tremors: Tremors can occur with certain medications or electrolyte imbalances, but they are not a common reason to withhold gentamicin unless accompanied by other signs of neurotoxicity. D. Photosensitivity: Photosensitivity is not a typical adverse effect of gentamicin. While clients may be advised to avoid excessive sun exposure for some medications, this side effect does not necessitate withholding the drug.
