D. Numbness and tingling of the hands and feet can indicate peripheral neuropathy, a known adverse effect of nitrofurantoin. It's essential for the nurse to recognize and communicate the potential seriousness of these symptoms to the client.

A. Numbness and tingling are not typically related to hydration status. While adequate hydration is important for overall health, it does not directly prevent numbness and tingling caused by medication side effects.

B. Constipation is not typically associated with elevated levels of gentamicin. Elevated gentamicin levels are not known to cause constipation.
