Medical Surgical Cardiac Angina #5

Question

The nurse correctly tells the client and family member how angioplasty with stenting is utilized to treat angina by using which explanation?

Answers

  1. “The blocked artery is bypassed to an area where there is proper blood flow for the heart muscle.”
    • Rationale:

      This answer is not correct because this describes a coronary artery bypass surgery (CABG), not angioplasty. A CABG bypasses the blocked artery to help his restore proper blood flow to the heart muscle.

  2. “The blood clot or plaque is dissolved, allowing adequate blood flow and oxygen to flow to the heart muscle.”
    • Rationale:

      This answer is not correct because angioplasty with stenting does not dissolve plaque like clot-busting, thrombolytic medications. Instead, it widens the narrow artery with a balloon and keeps the artery open with a wire mesh coil stent.

  3. “A tiny balloon is used to open the blocked artery and a wire mesh coil is placed to keep the artery open.”
    • Rationale:

      This answer is correct because angioplasty with stenting is best explained as the usage of a tiny balloon to open the blocked artery and a wire mesh coil placed to keep the artery open. Angioplasty, also called percutaneous coronary intervention (PCI), utilizes a tiny balloon that enters a large artery of the body to enter the coronary artery and widen a narrowed artery. After the artery is widened, a wire mesh stent coil is often placed to help the arter remain open. Opening the artery increases blood flow, thus increasing oxygen to the myocardium. This oxygenation to the myocardium eliminates angina and helps restore functioning of the heart muscle.

  4. “A tiny blade is used to cut away the plaque buildup and a stent is placed to keep blood flowing properly.”
    • Rationale:

      This answer is not correct because an atherectomy is a procedure typically used prior to angioplasty when the vessels are densely calcified to better prepare for the stenting procedure. This is done by using a rotating blade to remove plaque that is blocking an artery.

Overview

Angioplasty with stenting is best explained as the usage of a tiny balloon to open the blocked artery and a wire mesh coil placed to keep the artery open.

Explanation

Learning Outcomes

Angioplasty is an invasive procedure used to open the artery blocked by plaque build up from coronary artery disease. Angioplasty, also called percutaneous coronary intervention (PCI), utilizes a tiny balloon that enters a large artery of the body to enter the coronary artery and widen a narrowed artery. After the artery is widened, a wire mesh stent coil is often placed to help the arter remain open. Opening the artery increases blood flow, thus increasing oxygen to the myocardium. This oxygenation to the myocardium eliminates angina and helps restore functioning of the heart muscle. Any damaged muscle is said to have experienced infarction and will not function as it did before the blockage of blood flow. The sooner treatment is sought for angina, the less damage generally occurs to the heart muscle.
