A geriatric client received a narcotic analgesic before leaving the postanesthesia care unit to return to the regular unit. What is the priority nursing intervention for the nurse receiving the client on the regular unit?

A. Maintain the head of the client's bed at >45°: Elevating the head of the bed can help prevent aspiration and aid in breathing, but it is not the most critical safety measure immediately following narcotic administration in a geriatric client. B. Encourage fluid intake: While hydration is important, encouraging fluid intake is not a priority immediately after narcotic administration, especially in a post-op elderly client who may have altered consciousness or nausea. C. Create a restful, dark, quiet environment: Promoting rest can be beneficial, but ensuring safety takes precedence. Narcotics can cause sedation and confusion, so the priority should be to prevent injury rather than focus solely on comfort. D. Put side rails up and place bed in low position: Due to the sedative effects of narcotics, especially in elderly clients, the risk of falls is increased. Ensuring the bed is in a low position and side rails are up minimizes the risk of injury, making this the top safety priority.
