Answer to Question 1

D
Because dronedarone prolongs the QT interval by about 10 msec, it should not be used in pa-tients with a QT interval of more than 500 msec. It does not have significant pulmonary or thy-roid toxicity. It should not be used in patients with a PR interval of more than 280 msec.

Answer to Question 2

B
Ginkgo biloba can suppress platelet aggregation and will increase the risk of bleeding in patients taking antiplatelet medications and anticoagulants. Coenzyme Q-10, Ma Huang, and St. John's wort do not have antiplatelet actions.
