Answer to Question 1

ANS: B
Increasing the myocardial oxygen supply is indicated to treat ischemia. A decrease in fluid vol-ume is not appropriate. Heart rate should be decreased to decrease cardiac workload. Antibiotics are not the most beneficial; oxygen is.

Answer to Question 2

ANS: C
Chest pain that occurs at rest and at night is descriptive of Prinzmetal angina. Unstable angina is a form of acute coronary syndrome that results from reversible myocardial ischemia. Stable angi-na is predictable and occurs with activity. Silent angina has few, if any, symptoms.
