A nurse is caring for a client who has multiple sclerosis. Which of the following assessment findings should the nurse anticipate? (Select all that apply)

Choice A rationale Paresthesia, characterized by abnormal sensations such as tingling, numbness, or "pins and needles," is a common symptom in multiple sclerosis. This occurs due to demyelination and subsequent damage to sensory nerve pathways in the central nervous system, disrupting the normal transmission of sensory signals from the periphery to the brain. These sensory disturbances can fluctuate in intensity and location. Choice B rationale Nausea and vomiting are generally not considered primary or common assessment findings directly related to the pathophysiology of multiple sclerosis. While a client with MS might experience nausea and vomiting due to other co-existing conditions, medication side effects, or central nervous system lesions affecting areas involved in emesis (e.g., area postrema), it is not a hallmark symptom of the disease itself. Choice C rationale Dysphagia, or difficulty swallowing, is a significant symptom in multiple sclerosis, especially as the disease progresses. Demyelination and lesions in the brainstem or cranial nerves responsible for coordinating the complex muscular movements of swallowing can impair the pharyngeal and esophageal phases, increasing the risk of aspiration and nutritional deficiencies. Choice D rationale Spasticity, an increase in muscle tone leading to stiffness and involuntary muscle spasms, is a prevalent and often debilitating symptom in multiple sclerosis. It results from damage to the corticospinal tracts, which are descending motor pathways that normally inhibit muscle stretch reflexes. The loss of this inhibition leads to hyperexcitability of muscle stretch reflexes. Choice E rationale Vertigo, a sensation of spinning or dizziness, is a frequent complaint in multiple sclerosis. This symptom arises from demyelination and lesions affecting the brainstem or cerebellum, which are critical structures involved in maintaining balance and coordinating movement. Damage to these areas disrupts the processing of vestibular input, leading to disequilibrium and rotational sensations.
