Question

In teaching a patient about coronary artery disease, the nurse explains that the changes that occur in this disorder include which of the following (select all)?

A) diffuse involvement of plaque formation in coronary veins.
B) abnormal levels of cholestrol, particularly LDLs
C) accumulation of ipid and fibrous tissue within the coronary arteries
D) development of angia due to decreased blood supply to the heart muscle
E) chronic vasoconstriction of coronary arteries leading to permanent vasospasm

Answer 1

In coronary artery disease, abnormal cholesterol levels, especially LDLs, and the accumulation of lipid and fibrous tissue within the coronary arteries lead to conditions like angina due to reduced blood flow to the heart. Plaque forms in the arteries, not veins, and permanent vasospasm is not a typical feature of CAD.

Step-by-step explanation:

When teaching a patient about coronary artery disease (CAD), it is important to explain the changes that occur in this disorder, which include:

• B) abnormal levels of cholesterol, particularly low-density lipoproteins (LDLs)
• C) accumulation of lipid and fibrous tissue within the coronary arteries
• D) development of angina due to decreased blood supply to the heart muscle.

Option A is incorrect because plaque formation occurs in the arteries, not veins. Option E is incorrect because while temporary vasoconstriction can occur, chronic vasoconstriction leading to permanent vasospasm isn't a typical feature of CAD; rather, atherosclerosis is the primary pathology involving plaque accumulation in the arterial walls.
