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."
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.
