A nurse is evaluating teaching with a client who reports insomnia. Which of the following client statements indicates an understanding of the teaching?

Choice A reason: Taking a 1-hour nap each day can disrupt nighttime sleep patterns, worsening insomnia by reducing sleep drive. Naps longer than 20-30 minutes or late in the day interfere with the body’s circadian rhythm, decreasing the need for sleep at night, making this an incorrect understanding of insomnia management. Choice B reason: Going to bed at the same time each night, even if not tired, establishes a consistent sleep schedule, reinforcing the body’s circadian rhythm. This sleep hygiene practice conditions the brain to associate a specific time with sleep, improving sleep onset and quality, making it the correct statement for managing insomnia effectively. Choice C reason: Watching television in the bedroom before sleep stimulates the brain with blue light and engaging content, delaying melatonin production and sleep onset. Good sleep hygiene recommends avoiding screens in the bedroom to create a restful environment, making this an incorrect statement for effective insomnia management. Choice D reason: Stopping exercise 2 hours before bedtime is generally good advice, but it is not the most critical aspect of insomnia management compared to a consistent sleep schedule. Exercise close to bedtime may increase arousal, but a regular bedtime routine has a stronger impact on circadian rhythm regulation, making this less optimal.
