Answer to Question 1

C
Feedback:
Edrophonium is the drug of choice for diagnosing myasthenia gravis. Bethanechol is used to treat neurogenic bladder. Neostigmine is used for treatment of myasthenia gravis and could be used for diagnosis if edrophonium could not be used. Atropine is an anticholinergic drug and would not be used to test for myasthenia gravis.

Answer to Question 2

D
Feedback:
Pulmonary edema can occur when the heart is damaged and the left side of the heart is unable to effectively pump blood returning from the right side of the heart into systemic circulation. This lack of blood movement out of the lungs results in an increased hydrostatic pressure in the capillary beds of the lungs and the result can be pulmonary edema. Abdominal, liver, and peripheral edemas occur when the right side of the heart is failing and the returning venous blood pools in the organs and periphery.
