Answer to Question 1

A
Initial therapy can produce a severe headache. This response diminishes over the first few weeks of treatment.
A headache would not signify that the level of nitroglycerin is effective, nor does it indicate that the dose is too high.
Headache is a typical symptom, so a response indicating that it is atypical would also be incor-rect.

Answer to Question 2

A, B, C
Chronic use of Cafergot can lead to overdose, which should be suspected in this case because the patient has had frequent episodes of migraines and subsequent numbness and tingling in the fin-gers and toes. Overdose can cause ischemia secondary to constriction of peripheral arteries and arterioles, which can cause the extremities to become cold, pale, and numb. Muscle pain develops, and gangrene eventually may result.
Nausea and vomiting are side effects, not the effects of a possible overdose of Cafergot.
