A nurse is caring for a client who has an anxiety disorder and reports ongoing difficulty sleeping at night.Which of the following recommendations should the nurse make?

Choice A rationaleConsuming red wine before bed, even in small amounts, can disrupt sleep architecture. While alcohol might initially induce drowsiness, it often leads to fragmented sleep later in the night as the body metabolizes it, resulting in poor sleep quality and reduced restorative sleep.Choice B rationaleStaying in bed for prolonged periods when unable to sleep can create a negative association between the bed and wakefulness. This can increase anxiety about sleep and perpetuate insomnia. It is generally recommended to get out of bed and engage in a relaxing activity until feeling sleepy.Choice C rationaleExercising vigorously close to bedtime can be stimulating and raise core body temperature, making it harder to fall asleep. The body needs time to cool down for optimal sleep initiation. It is generally recommended to avoid intense exercise at least a few hours before bed.Choice D rationaleCaffeine is a stimulant that can interfere with sleep initiation and maintenance. Limiting caffeine intake, especially in the afternoon and evening, can significantly improve sleep quality by reducing its stimulating effects on the central nervous system. Normal caffeine intake should be limited, and eliminating it closer to bedtime is beneficial for sleep.
