A nurse is caring for a 75-year-old patient who has been prescribed a new medication. The nurse knows that the process of converting the medication to a form that is easily excreted from the body is known as metabolism. Which consideration should the nurse take when administering this new medication?

A. Metabolism is affected by aging in the form of decreased kidney and liver function: In older adults, liver enzyme activity and renal clearance often decline, which can slow drug metabolism and excretion. This increases the risk of drug accumulation and toxicity, making dose adjustments and careful monitoring essential when administering new medications. B. Bedtime of the patient: The patient’s bedtime may affect adherence or convenience but does not directly impact metabolism or excretion. Timing related to sleep is not the priority when considering age-related pharmacokinetics. C. Time of day for administering the medication: While timing may influence therapeutic effect for some drugs, it is less critical than considering how aging affects drug metabolism and elimination. Pharmacokinetic changes take precedence in older adults. D. Generic vs. brand name: The choice between generic and brand name may affect cost or patient preference but does not impact the body’s metabolism of the drug. Age-related organ function remains the key consideration.
