The nurse uses which statement to best describe the link between atherosclerosis and coronary artery disease?
 
  1. Coronary artery disease results when atherosclerotic plaques break off and cause ischemia.
  2. Coronary artery disease results when atherosclerotic plaques block the inside of the blood vessels.
  3. Coronary artery disease results when atherosclerotic plaques grow large enough to rupture the coronary blood vessels.
  4. Coronary artery disease results when there are spasms around the atherosclerotic areas.

Question 2

The nurse realizes that client teaching regarding the cause of anginal pain was effective when the client makes which statement?
 
  1. The pain is related to remodeling of the heart muscle caused by narrowed arteries.
  2. The heart is not pumping enough blood out with each beat because of narrowed arteries.
  3. The pain is from a lack of oxygen getting to the heart, which is caused by narrowed arteries.
  4. The pain comes from the heart beating irregularly because of narrowed arteries.

Answer to Question 1

Correct Answer: 2
Rationale 1: While an embolism can occur, they are typically not called coronary artery disease.
Rationale 2: Coronary artery disease is the progressive buildup of atherosclerotic plaque that could eventually occlude the artery. The plaque also can rupture, leading to a myocardial infarction.
Rationale 3: Rupture of a coronary vessel due to atherosclerotic plaque is unlikely and not part of coronary artery disease.
Rationale 4: Spasms can occur in atherosclerotic areas but are not part of classic coronary artery disease.

Answer to Question 2

Correct Answer: 3
Rationale 1: Remodeling of the heart muscle can make the heart more susceptible to angina, but it is not the actual source of angina.
Rationale 2: Low cardiac output is not the actual source of angina but can be a contributing factor.
Rationale 3: Angina pectoris is acute chest pain caused by the coronary arteries' inability to maintain adequate oxygenation to meet the metabolic demands of the myocardium. This is usually caused by a narrowing of the coronary vessels.
Rationale 4: An irregular heartbeat is not the actual source of angina but can be a contributing factor.
