A nurse in a long-term care facility is caring for a client who has dementia and reports difficulty falling asleep at night. Which of the following actions should the nurse take to promote adequate rest?

A. Schedule the client for a morning group fitness class at the facility: Regular morning exercise promotes healthy sleep patterns by helping regulate the body's circadian rhythm. Engaging in physical activity early in the day can reduce restlessness at night. B. Limit the client to no more than four caffeinated beverages a day: While caffeine should be limited, the most effective approach is to avoid caffeine entirely in the afternoon and evening to prevent sleep disruption, rather than just limiting it to four beverages a day. C. Walk around the hallway with the client an hour before bedtime: Although light physical activity can promote sleep, intense exercise or walking too close to bedtime can sometimes increase alertness and make it harder for the client to fall asleep. D. Allow the client several hours in the afternoon to take a nap: Long naps, especially in the afternoon, can disrupt the client's sleep cycle and make it more difficult for them to fall asleep at night. Limiting naps during the day is typically more helpful.
