The nurse is caring for a client newly diagnosed with multiple sclerosis. Which statement by the client indicates that additional instruction is needed?

Choice A rationale Multiple sclerosis is a chronic demyelinating disease where nerve fibers in the central nervous system lose their protective coating. Exposure to high temperatures, such as hot baths, can cause a temporary worsening of neurological symptoms, a phenomenon known as Uhthoff's sign. Heat slows the conduction of nerve impulses through already damaged axons. Clients should use lukewarm water to avoid exacerbating fatigue, muscle weakness, or visual disturbances that occur with increased body temperature. Choice B rationale Fatigue is one of the most common and debilitating symptoms of multiple sclerosis, often described as an overwhelming sense of exhaustion. Scheduling regular rest periods helps the client manage their energy levels and prevents the physical overexertion that can trigger a flare or worsen existing symptoms. This strategy promotes a balance between activity and recovery, allowing the client to maintain a higher quality of life and better functional independence in their daily activities. Choice C rationale Diplopia, or double vision, occurs in multiple sclerosis due to lesions in the brainstem or cranial nerves that coordinate eye movements. Wearing an eye patch over one eye is a common compensatory strategy to eliminate the confusing second image, thereby improving safety and reducing dizziness or nausea associated with visual distortion. This statement indicates the client understands how to manage sensory symptoms effectively and safely during a period of active neurological dysfunction or relapse. Choice D rationale While heat is a more common trigger, extreme cold or sudden temperature changes can also exacerbate symptoms like muscle spasticity or sensory disturbances in multiple sclerosis. Cold environments may cause muscles to tighten or result in increased pain and discomfort for the client. Avoiding getting chilled helps maintain a stable internal environment, which is beneficial for nerve conduction and muscle relaxation. This shows the client is aware of environmental factors that impact their condition.
