A nurse is caring for a client who is scheduled for a Tensilon challenge test to check for myasthenia gravis. Which of the following findings should the nurse identify as a positive result?
Muscle strength becomes temporarily stronger.
A "pill-rolling" tremor appears.
Electrical charge in the muscle increases in intensity.
Muscle strength shows no change.
The Correct Answer is A
A. A positive result in a Tensilon test is indicated by a temporary improvement in muscle strength following the administration of edrophonium (Tensilon), confirming the diagnosis of myasthenia gravis.
B. A "pill-rolling" tremor is associated with Parkinson's disease, not myasthenia gravis, and is not relevant to this test.
C. While muscle electrical activity can be assessed in other tests, the Tensilon test specifically evaluates muscle strength changes, not electrical charge intensity.
D. No change in muscle strength would suggest a negative result for myasthenia gravis, indicating that the test did not confirm the diagnosis.
