Answer to Question 1

D
The Tensilon test provides information as to whether a patient is experiencing a myasthenic crisis or a cholinergic crisis. If the patient's symptoms worsen with Tensilon, the individual most likely is overmedicated and experiencing a cholinergic crisis; the patient should then be given atropine as an antidote. If the patient's symptoms improve with the administration of Tensilon, the person most likely was undermedicated and is experiencing a myasthenic crisis.
The occupational and family history will not provide information that can differentiate between the two crises.
Serum levels of cholinesterase inhibitors would not provide information that can differentiate between the two crises.
Assessing the patient for muscle weakness will not provide specific enough information to diffe-rentiate between the two crises.

Answer to Question 2

d
