Answer to Question 1

Correct Answer: 2, 3, 5
The manifestations of myasthenia gravis correspond to the muscles involved. Initially, the eye muscles are affected and the patient experiences either diplopia (unilateral or bilateral double vision) or ptosis (drooping of the eyelid). Patients may have periods of dysphagia (difficulty swallowing) and dysarthria (problems with speech). Although treatments such as glucocorticoid and immunosuppressant therapy may result in an increase in muscle strength, exercise tends to fatigue muscles, while rest will improve function. The voice is weak with a muffled nasal quality.

Answer to Question 2

Correct Answer: 1
Adrenocorticotropic hormone (ACTH) decreases inflammation and suppresses the immune system. Meperidine (Demerol) is a narcotic analgesic and would not be used to treat MS. MAO inhibitors are used to treat depression. Rivastigmine tartrate (Exelon) is used in the treatment of Alzheimer disease.
