Answer to Question 1

ANS: B
Percutaneous transluminal coronary angioplasty, a balloon dilation of the coronary arteries, may be the procedure of choice for select patients with significant atherosclerotic narrowing in a major coronary artery. A balloon-tipped catheter is passed through a guiding catheter into the area of the coronary artery with atherosclerotic material (plaque). The balloon is inflated by a hydraulic pump to compress plaque against the arterial lining and dilate the arterial wall, thus enlarging the lumen.

Answer to Question 2

ANS: A
The Maze procedure makes a series of small incisions in the atria in order to interrupt the electrical pathways that are causing the cardiac dysrhythmia.
