Medical Surgical Myocardial Infarction #6

Question

The nurse is caring for a client who is scheduled for a percutaneous transluminal coronary angioplasty (PTCA). Which information by the nurse best explains the procedure?

Answers

  1. “The procedure involves attaching grafts to replace blocked coronary arteries.”
    • Rationale:

      This answer is not correct because percutaneous transluminal coronary angioplasty (PTCA) is a minimally invasive procedure that uses an inflatable balloon located on the end of a catheter to open blocked coronary arteries. Coronary artery bypass graft (CABG) or “open heart surgery” is an extremely invasive surgery that uses the attachment of a graft to bypass blocked arteries. This is not PTCA.

  2. “The procedure includes threading a catheter with a sharp blade at its tip to scrape plaque build-up.”
    • Rationale:

      This answer is not correct because a procedure called atherectomy is where plaque is removed through a catheter-ended blade or burr. Percutaneous transluminal coronary angioplasty (PTCA) uses an inflatable balloon located on the end of a catheter to open blocked coronary arteries.

  3. “The procedure involves opening a blocked artery with an inflatable balloon located on the end of a catheter.”
    • Rationale:

      This answer is correct because percutaneous transluminal coronary angioplasty (PTCA) is a minimally invasive procedure that uses an inflatable balloon located on the end of a catheter to open blocked coronary arteries. This procedure’s purpose is to restore blood flow and oxygen to the heart so the heart will function optimally. These blood vessels are blocked due to atherosclerotic, cholesterol-filled plaque.

  4. “The procedure involves a catheter with a monitor on its tip which will stay in place during open heart surgery.”
    • Rationale:

      This answer is not correct because PTCA is not used during open heart surgery. Percutaneous transluminal coronary angioplasty (PTCA) is a minimally invasive procedure that uses an inflatable balloon located on the end of a catheter to open blocked coronary arteries. This procedure’s purpose is to restore blood flow and oxygen to the heart so the heart will function optimally.

Overview

Percutaneous transluminal coronary angioplasty (PTCA) is a procedure that is minimally invasive used to open coronary arteries by use of an inflatable balloon located at the end of a catheter. This procedure’s purpose is to restore blood flow and oxygen to the heart so the heart will function optimally.

Explanation

Learning Outcomes

Percutaneous transluminal coronary angioplasty (PTCA) is a minimally invasive procedure that uses an inflatable balloon located on the end of a catheter to open blocked coronary arteries. This procedure’s purpose is to restore blood flow and oxygen to the heart so the heart will function optimally. These blood vessels are blocked due to atherosclerotic, cholesterol filled plaque. Stenting is often used with PTCA to prop the opened artery. When the left anterior descending (LAD) is not blocked, PTCA and stenting is often the first choice of treatment for blocked coronary arteries.

Test Taking Tip

When your memory fails you and you are grasping at straws to figure out the correct answer, break down the word and figure it out! Trans-luminal coronary angio-plasty: going across (trans) the lumen (luminal) of the vessel (angio) of the heart (coronary) to make changes (plasty) of that particular part (coronary artery). So, the perfect answer selection includes going into an artery with a balloon and opening (making changes to-plasty) the blocked artery with that balloon.
