Answer to Question 1

ANS: B
Normally, the SA node, which is located in the upper portion of the right atrium, has the greatest degree of automaticity and therefore paces the heart.

Answer to Question 2

ANS: C
Treatment for atrial fibrillation is similar to the treatment for atrial flutter. However, patient with sustained atrial fibrillation is often treated with anticoagulants or antithrombolytic medications to treat potential blood clot formation, medications to slow the heart rate, and cardioversion.
