Answer to Question 1

ANS: B
This patient has unstable angina, and the next step, when pain is unrelieved by sublingual nitroglycerin, is to give intravenous nitroglycerin and a beta blocker. ACE inhibitors should be given to patients with persistent hypertension if they have left ventricular dysfunction or congestive heart failure (CHF). Ranolazine is a first-line angina drug, but it should not be given with quinidine because of the risk of increasing the QT interval. Supplemental oxygen is indicated if cyanosis or respiratory distress is present. IV morphine may be given if the pain is unrelieved by nitroglycerin.

Answer to Question 2

ANS: C
Gemfibrozil displaces warfarin from the plasma albumin, thereby increasing anticoagulant effects. The level of gemfibrozil will not be increased or decreased. The anticoagulation effects will not be reduced, because free-floating drug is present in the system; the dosage of warfarin may need to be reduced.
