The patient asks the nurse, "Will I have to take this antiarrhythmic agent for the rest of my life?" The nurse, having reviewed the CAST study, responds by saying what?
A) "Yes, you will have to take this drug for life."
B) "The drug is indicated for short-term treatment of life-threatening ventricular arrhythmias."
C) "This drug may need to be changed but you'll take an antiarrhythmic for life."
D) "After the arrhythmia is corrected, the drug will be stopped."

Feedback:
The CAST study, a large research study run by the National Heart and Lung Institute, found that long-term treatment of arrhythmias may have an uncertain effect on mortality, and in some cases may actually lead to increased cardiac death, which is the basis for the current indication for antiarrhythmics to be used only short-term to treat life-threatening ventricular arrhythmias.
