A test that is used to diagnose myasthenia gravis (MG) is ordered by the physician. Because the test involves an injection of a drug that makes muscle strength improve for about five minutes, the nurse realizes that this test most likely is:
 
  1. the Tensilon test.
  2. a computed tomography (CT) scan of the legs.
  3. a nerve stimulation study.
  4. analysis of antiacetylcholine receptor antibodies.

Question 2

The nurse is assessing a patient with Guillain-Barr syndrome. What should the nurse expect to assess in this patient?
 
  Select all that apply.
  1. increased muscular weakness
  2. increased lower extremity edema
  3. increased confusion
  4. increased intolerance to light
  5. decreased deep tendon reflexes

Answer to Question 1

Correct Answer: 1
The Tensilon test produces a five-minute increase in muscle strength. A computed tomography (CT) scan of the legs is not indicated for this patient. The nerve stimulation study and the analysis of antiacetylcholine receptor antibodies are tests that can be done to help diagnose MG, but do not require a drug injection.

Answer to Question 2

Correct Answer: 1, 5
As Guillain-Barr develops, the patient will, experience muscle weakness with paralysis from altered nerve conduction (motor nerves become demyelinated). One manifestations of the acute stage is decreased deep tendon reflexes. Increased lower extremity edema, confusion, and intolerance to light are not manifestations of this disorder.
