Jane, a 20-year old college student is admitted to the hospital with a tentative diagnosis of myasthenia gravis. She is scheduled to have a series of diagnostic studies for myasthenia gravis, including a Tensilon test. In preparing her for this procedure, the nurse explains that her response to the medication will confirm the diagnosis if Tensilon produces:

The client shows a marked improvement of muscle strength.

The client has muscles become weakened due to the impaired ability to respond to nerve signals

There is reduced amplitude of electrical stimulation in the muscle.

The anti-acetylcholine receptor antibodies are present.

Answer and Explanation

The Correct Answer is A

Choice A rationale: The Tensilon test involves injecting edrophonium, and in myasthenia gravis, temporary improvement in muscle strength confirms the diagnosis by demonstrating increased acetylcholine activity at the neuromuscular junction.

Choice B rationale: This describes the pathophysiology of myasthenia gravis but doesn’t directly confirm the diagnosis via the Tensilon test.

Choice C rationale: While this may be seen in myasthenia gravis, the Tensilon test specifically aims to observe improved muscle strength after administration.

Choice D rationale: While the presence of these antibodies is a characteristic of myasthenia gravis, the Tensilon test is used to assess the immediate response to the medication for diagnostic confirmation.
