A client with multiple sclerosis (MS) is frustrated by tremors associated with the disease. How should the nurse explain why these tremors occur? Due to the demyelination of neurons that occurs in MS:

  • A. there is an imbalance in acetylcholine and dopamine, leading to tremors.
  • B. there is a disruption in nerve impulse conduction, causing tremors.
  • C. muscles are unable to receive impulses, resulting in tremors.
  • D. the reflex arc is disrupted, leading to muscle tremors.
Correct Answer: B

Rationale: In multiple sclerosis (MS), demyelination of neurons disrupts nerve impulse conduction. This disruption in nerve impulses can lead to tremors, explaining why the client experiences tremors in MS. Choice A is incorrect because tremors in MS are primarily due to nerve conduction issues, not an imbalance in acetylcholine and dopamine. Choice C is incorrect as it oversimplifies the process; the issue lies in nerve impulses, not the muscle's ability to receive them. Choice D is incorrect as the primary cause of tremors in MS is the disruption in nerve impulse conduction, not the reflex arc being disrupted.
