Final answer:
The nurse would recommend that the patient follows his usual bedtime routine for better sleep as consistency is crucial for good sleep hygiene and can effectively assist with insomnia treatment.
Step-by-step explanation:
To help a patient get to sleep, the nurse suggests that he follow his usual bedtime routine if possible. Having a consistent routine can cue the body for sleep, maintaining healthy sleep habits. Drinking too much water can lead to disruptions from needing to use the bathroom, and a large snack can lead to discomfort. Sedative-hypnotics should only be used under the guidance of a healthcare professional and not as a regular sleep aid due to risks of dependency and disruption of natural sleep cycles. Instead, it is best to maintain regular sleep schedules and avoid stimulating activities before bedtime, as recommended for insomnia treatment.
