The nurse is assessing a patient with suspected myasthenia gravis. The nurse is aware that which assessment finding supports this diagnosis?

Postural hypotension

Diplopia

Dizziness with sudden head movement

Hand tremors during voluntary movement

Answer and Explanation

The Correct Answer is B

A. Postural hypotension is more commonly associated with autonomic dysfunction (e.g., in Parkinson’s disease or dehydration) and is not a hallmark sign of myasthenia gravis.

B. Diplopia (double vision) is a classic symptom of myasthenia gravis. The disease causes weakness of voluntary muscles, especially those that control eye and eyelid movement, leading to visual disturbances.

C. Dizziness with sudden head movement is often linked to vestibular dysfunction (e.g., benign paroxysmal positional vertigo), not myasthenia gravis.

D. Hand tremors during voluntary movement are more suggestive of cerebellar disorders or essential tremor, not myasthenia gravis, which primarily causes muscle weakness without tremors.
