A nurse is reinforcing teaching with a newly licensed nurse about age-related changes that affect medication administration for older adult clients.Which of the following information should the nurse include?

Choice A rationale:Renal excretion time slows for medication. As people age, kidney function gradually decreases, which slows the excretion of medications. This can lead to increased levels of the drug in the body, which can increase the risk of side effects.Choice B rationale:Hepatic enzymes do not process medications more rapidly in older adults. In fact, liver function also decreases with age, which can slow the metabolism of medications.Choice C rationale:Brain receptors do not become less sensitive to medications in older adults. The sensitivity of brain receptors to medications can vary widely and is not necessarily related to age.Choice D rationale:Gastric emptying rate does not increase with age. On the contrary, it often slows down, which can affect the absorption of some medications.
