Final answer:
To reduce fatigue for patients with MS, the nurse should advise resting in an air-conditioned room to help stay cool and manage fatigue levels effectively.
Step-by-step explanation:
To reduce fatigue in patients with multiple sclerosis (MS), the nurse should tell the patient to rest in an air-conditioned room. MS symptoms can include fatigue, which is exacerbated by heat. Therefore, staying cool is essential for managing fatigue. A hot bath would likely increase fatigue by raising the body's temperature. Additionally, while muscle relaxants can ease muscle spasms, increasing the dose without a doctor's supervision could lead to side effects and is not specifically related to managing fatigue.
While avoiding naps might seem like a good idea to ensure better night-time sleep, short rest periods during the day can help manage MS fatigue without interfering with night-time sleep.
