A nurse is caring for a client who reports difficulty falling and remaining asleep. Which of the following actions should the nurse take to promote sleep?

A. Encourage exercise 1 hr prior to sleep: Vigorous exercise immediately before bedtime can increase alertness and delay sleep onset. Exercise is best scheduled earlier in the day to promote better sleep quality. B. Provide a warm cup of coffee 30 min before bedtime: Caffeine is a stimulant that can interfere with the ability to fall and stay asleep. Offering coffee close to bedtime is counterproductive to promoting sleep. C. Turn on the client's television at bedtime: Television and other electronic devices emit light and provide stimulation that can disrupt circadian rhythms and inhibit melatonin release, making it harder to fall asleep. D. Encourage the client to take a warm bath before bedtime: A warm bath helps relax muscles and promotes a decrease in core body temperature afterward, which can facilitate sleep onset. This is an effective, nonpharmacologic intervention to improve sleep quality.
