Final answer:
A nurse aide should refer the client's family member to the nurse when asked about the client's medication.
Step-by-step explanation:
When a client's family member asks a nurse aide about the medications the client is receiving, the nurse aide should refer the family member to the nurse. This is because the nurse is responsible for providing accurate and up-to-date information about the client's medication. It is important for the nurse to review the client's medication list, assess the client's condition, and communicate the necessary information to the family member.
