Final answer:
The nurse may suggest deep breathing exercises, snug-fitting nightwear, or walking to help a patient with trouble sleeping.
Step-by-step explanation:
When caring for a patient who is having trouble sleeping, the nurse may suggest several actions. One of the recommended actions is to encourage deep breathing, which can help calm the patient's mind and relax their body. Another option is to suggest snug-fitting nightwear, as comfortable sleepwear can promote better sleep. Walking with the patient may also be beneficial, as light physical activity can help tire them out and induce sleep.
