A Test That Is Used to Diagnose Myasthenia Gravis (MG)is

A test that is used to diagnose myasthenia gravis (MG) is ordered by the doctor. Because the test involves the injection of a drug that makes muscle strength improve for about five minutes, the nurse realises that this test likely is:

A) an analysis of antiacetylcholine receptor antibodies.
B) a nerve stimulation study.
C) a magnetic resonance imaging (MRI) of the legs.
D) a Tensilon test.
