Which clinical finding would the nurse anticipate for a client who has an exacerbation of multiple sclerosis?

Which clinical finding would the nurse anticipate for a client who has an exacerbation of multiple sclerosis?

• A. Double vision
• B. Resting tremors
• C. Flaccid paralysis
• D. Scanning speech

Answer: (D)

In multiple sclerosis, an exacerbation brings new demyelinating lesions in the CNS that disrupt how signals are coordinated. Scanning speech—speech that is slow and broken with pauses between syllables—reflects impaired coordination of the muscles used for articulation due to brain involvement. This feature is particularly characteristic of MS because it points to disrupted neural timing and control of speech pathways. Other options can occur in MS but are less typical as defining features: double vision can result from optic neuritis, a common MS issue, but it’s not as specific to an exacerbation as the distinctive dysarthria; rest tremor is more characteristic of Parkinsonian disorders; flaccid paralysis suggests lower motor neuron damage, which is not the typical pattern in MS, where upper motor neuron signs like spasticity are more common. So the presence of scanning speech during an MS flare aligns with how demyelination affects the precise coordination required for articulate speech.
