Final answer:
The nurse can delegate giving a backrub and dimming the lights to the nursing assistant at bedtime.
Step-by-step explanation:
According to sleep hygiene guidelines, the nurse can delegate the following actions to the nursing assistant at bedtime:
- Giving the patient a backrub
- Dimming the lights in the patient's room
These actions promote relaxation and create a soothing environment that can aid in sleep. On the other hand, turning on quiet music, giving a patient a cup of coffee, and monitoring the effect of sleeping medication should be done by the nurse as they require specific decision-making and medication management skills.
