Answer to Question 1

ANS: B
The presentation of angina pectoris is highly variable. The sensation of discomfort may be described as squeezing, tightness, choking, pressure, burning, or heaviness. Pain or discomfort may radiate to the neck, lower jaw, shoulder, and arm. Attacks can last from 30 seconds to 30 minutes. Anginal pain usually does subside with rest. Sustained pain is usually indicative of a myocardial infarction. Although angina pain may subside in this way, in general, it is highly variable in how it is manifested. Anginal pain may or may not correlate with the amount of myocardial damage.

Answer to Question 2

ANS: C
Tolerance to nitrates can develop rapidly, particularly if large doses are administered frequently. Allergy to nitrates is highly unlikely. Increasing dosages and frequency of nitrate use is more likely to reflect deterioration of cardiac function than dependence on the medication. Nausea is not a common adverse effect of nitrate treatment.
