Answer to Question 1

ANS: A, B, D, E
ACE inhibitors have shown benefit in reducing the incidence of adverse outcomes in patients with coronary artery disease (CAD) and are recommended as part of therapy. Antiplatelet drugs are recommended to reduce the risk of thrombus formation. CCBs are used as adjuncts to nitroglycerin and are safe in patients with asthma and depression. Cholesterol-lowering drugs are recommended to help slow the progression of CAD. Beta blockers are not recommended in patients with asthma or depression.

Answer to Question 2

ANS: B
Agents that inhibit CYP3A4 can increase levels of ranolazine and also the risk of torsades de pointes. Macrolide antibiotics, such as azithromycin, are CYP3A4 inhibitors. Respiratory toxicity is not an expected effect with this patient. The patient's blood pressure is not elevated enough to notify the provider. Amlodipine is the only CCB that should be used with ranolazine.

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
