While assessing a client on gentamicin sulfate, what is a crucial question for the nurse to ask?

When a client is being assessed while on gentamicin sulfate, a crucial question to ask is whether they are experiencing any hearing difficulties. Gentamicin is an aminoglycoside antibiotic that is known to have ototoxic effects, which can lead to hearing loss or problems with balance. These side effects are a significant concern, especially for patients receiving high doses or extended therapy, as they can result from gentamicin's toxicity to the inner ear structures.

By inquiring about hearing difficulties, the nurse can gauge the potential adverse effects of the medication and take appropriate action if necessary, such as adjusting the dose or considering an alternative treatment. This assessment is vital for patient safety and ensuring the ongoing effectiveness of the treatment regimen with gentamicin.

While the other questions may be relevant in a broader clinical assessment, they do not specifically address the known risks associated with gentamicin therapy.
