A nurse is caring for an adult client who reports having trouble getting to sleep at night. Which of the following recommendations should the nurse make?

A. "Establish a daily exercise routine." Regular physical activity helps regulate the sleep-wake cycle and promotes deeper sleep. Exercising earlier in the day enhances sleep quality, but vigorous exercise close to bedtime should be avoided as it can be stimulating. B. "Keep the television volume low while you are trying to fall asleep." Watching television before bed can interfere with melatonin production due to blue light exposure, making it harder to fall asleep. A dark, quiet environment is recommended for better sleep. C. "Remain in bed until you fall asleep." Staying in bed while struggling to sleep can reinforce insomnia. It is recommended to get out of bed and engage in a relaxing activity if unable to sleep within 20 minutes, then return when drowsy. D. "Sleep longer hours on the weekend." Sleeping in on weekends disrupts the body's internal clock and can worsen sleep difficulties. Maintaining a consistent sleep schedule, even on weekends, helps regulate circadian rhythms and improve sleep quality.
