Which intervention could help address sleep disturbance in this patient?

• A. Encourage regular sleep-wake schedule and daytime activity.
• B. Provide frequent caffeine.
• C. Increase evening stimulation.
• D. Encourage prolonged bed rest.

Answer: (A)

Regulating the sleep-wake cycle and adding daytime activity helps reset the body's internal clock and improve sleep quality. When routines are consistent, the brain learns when it’s time to wind down and when it should be alert, which reduces fragmented sleep and preserves energy for the day. For someone with schizophrenia, sleep disturbance is common and can worsen daytime functioning and mood; a stable routine plus daytime activities like light exposure, exercise, and social engagement can improve both sleep and overall symptoms.

Frequent caffeine use is a stimulant that can keep someone awake and disrupt sleep architecture, while increasing evening stimulation further delays sleep and harms sleep quality. Prolonged bed rest reduces daytime cues like light exposure and activity, which can throw off circadian timing. So, the best intervention for addressing sleep disturbance in this context is encouraging a regular sleep-wake schedule and daytime activity.
