Myasthenic crisis and cholinergic crisis are the major complications of myasthenia gravis. Which of the following is important for a physician assistant to know when caring for a patient in crisis?
  1. Weakness and paralysis of the muscles for swallowing and breathing occur in either crisis
  2. Cholinergic drugs should be administered to prevent further complications associated with the crisis
  3. The clinical condition of the patient usually improves after several days of treatment
  4. Loss of body function creates high levels of anxiety and fear
Explanation
Answer: A - The patient cannot handle his own secretions, and respiratory arrest may be imminent. Atropine may be administered to prevent crisis. Anticholinergic drugs are administered to increase the levels of acetylcholine at the myoneural junction. Cholinergic drugs mimic the actions of the parasympathetic nervous system and would not be used.
