A patient reports ongoing sleep difficulties during an annual visit. Which measure is most appropriate for the nurse to suggest to improve the patient's sleep?

• A. Minimize light when going to sleep
• B. Take daytime naps to reduce fatigue
• C. Keep a sleep log of times asleep
• D. Increase evening caffeine intake

Answer: (C)

When addressing ongoing sleep difficulties, the first step is to gather detailed, real-world data on the patient’s sleep patterns. Keeping a sleep log of times asleep and awake is the most useful measure because it creates a clear record of what’s happening over several days. This diary should capture bedtime, actual sleep onset, number and duration of awakenings, total sleep time, daytime naps, caffeine or alcohol use, exercise, and environmental factors like light and noise. With this information, you can see patterns—whether the person is having trouble falling asleep, staying asleep, or both—and how daytime factors might be influencing night symptoms. It also provides a baseline to track changes after implementing sleep-hygiene strategies, and helps tailor recommendations to the individual, such as establishing a consistent wake-time, limiting stimulating substances, or adjusting naptimes.

Minimizing light at bedtime is a helpful sleep-h hygiene tip, but on its own it doesn’t provide the data needed to tailor interventions. Increasing evening caffeine would worsen sleep, and daytime naps can perpetuate insomnia by reducing drive to sleep at night. A sleep log, by contrast, gives actionable insight and supports collaborative planning between patient and clinician.
