A nurse is planning care for a client who reports having difficulty sleeping. Which of the following interventions should the nurse include in the plan of care?

The correct answer is B: Schedule exercise activities at least 3 hr before bedtime. Exercise can help promote better sleep by reducing stress and anxiety, and increasing the release of endorphins, which can aid in relaxation. However, exercising too close to bedtime can have the opposite effect, as it raises body temperature and stimulates the nervous system. Providing hot chocolate (A) may not be helpful as it contains caffeine, which can interfere with sleep. Keeping soft music playing (C) may be distracting and not address the underlying issue. Scheduling mealtime 2 hr before bedtime (D) may be beneficial for digestion but does not directly address sleep difficulties.
