Answer to Question 1

ANS: A
Ibutilide (Covert) is the drug of choice for pharmacologic conversion from atrial flutter to sinus rhythm.
If the patient stayed in atrial flutter, warfarin would be instituted to reduce the risk of stroke.
Verapamil and diltiazem might be given to control the ventricular rate if the patient remained in atrial flutter.

Answer to Question 2

ANS: B
Lung damage is the most serious adverse effect of amiodarone (Cordarone).
Cardiovascular toxicity is evidenced by a paradoxical increase in dysrhythmic activity.
The patient's symptoms (dyspnea, cough, chest pain) are similar to those of heart failure and pneumonia; however, these symptoms are associated with the prolongation of amiodarone in the system.
No evidence indicates an impending MI.
