A nurse is planning to give pre-procedure teaching to a patient about the benefits of percutaneous transluminal coronary angioplasty (PTCA ). Which of the following is the most important for the patient to be taught?
  1. The stent helps to increase the coronary blood flow
  2. The procedure is done through distal arteries.
  3. Balloon pressure decreases plaque size and stretches the vessel.
  4. The goal is to increase blood flow by reducing plaque build-up.
Explanation
Answer: D -The most important fact for the patient to know is that the goal of PTCA is to increase blood flow to the coronary arteries by reducing plaque build-up. The procedure involves the use of a catheter introduced through the femoral, brachial, or radial artery into the diseased coronary artery and balloon pressure is applied to the area of plaque formation to decrease plaque size and/or stretch the vessel wall. A stent is often placed after opening the vessels.
