Question

a nurse is caring for an older adult client who has kidney disease and a new prescription for cimetidine. the nurse should instruct the client to report which of the following manifestations? dry mouth cellulitis lethargy myalgia

Explanation:

Cimetidine is primarily excreted by the kidneys; in clients with kidney disease, the drug can accumulate, leading to central nervous system (CNS) effects. Lethargy is a CNS manifestation of cimetidine toxicity. Dry mouth is a mild, common side effect not requiring urgent reporting. Cellulitis and myalgia are not associated with cimetidine use in this context.

Answer:

C. Lethargy
