A nurse is providing teaching to an older adult client about methods to promote nighttime sleep. Which of the following instructions should the nurse include?

A. Correct – A light snack (such as crackers and milk) can prevent hunger-related wakefulness and promote relaxation. B. Incorrect – Long naps (>30 minutes) can disrupt nighttime sleep. If necessary, short naps should be limited to 20–30 minutes. C. Incorrect – Exercise before bed can stimulate the nervous system, making it harder to fall asleep. D. Incorrect – If unable to sleep after 20–30 minutes, the client should get out of bed and engage in a quiet activity (e.g., reading) to avoid associating the bed with wakefulness.
