What is the most effective method the nurse can implement to elicit an accurate medication assessment on new clients in a geriatric outpatient clinic setting?

A. Work with a family member to make a list of the clients' medications: Helpful if the client has cognitive issues, but it may not be fully accurate, especially if the family member is not aware of OTC or herbal meds. B. Ask the clients to make a list of all current medications: Older adults may forget some medications, misname them, or not include supplements or OTC drugs. C. Ask that the client bring in all of the medications that they are currently taking: Known as a "brown bag review," this is the most accurate method because it allows the nurse to directly verify prescriptions, dosages, and administration patterns. D. Request the clients' previous primary care providers to provide a list of prescribed medications: Past prescription lists may be outdated and don't account for medications obtained from other providers or pharmacies.
