The nurse is assisting in the care of a client who is being evaluated for possible myasthenia gravis. The health care provider gives a test dose of edrophonium (Tensilon). Evaluation of the results indicates that the test is positive
Which of the following would be the expected response noted by the nurse? 1. Joint pain for the next 15 minutes
2. A decrease in muscle strength within 1 to 3 minutes
3. An increase in muscle strength within 1 to 3 minutes
4. Feelings of faintness or dizziness for 5 to 10 minutes
3
Rationale: Edrophonium (Tensilon) is a short-acting acetylcholinesterase inhibitor used to diagnose myasthenia gravis. An increase in muscle strength should be seen in 1 to 3 minutes following the test dose if the client does have the disease. If no response occurs, another dose is given over the next 2 minutes and muscle strength is tested again. If no increase in muscle strength occurs with this higher dose, the muscle weakness is not caused by myasthenia gravis. Clients who receive injections of this medication commonly demonstrate a drop of blood pressure, feel faint and dizzy, and are flushed.
