The nurse is educating a group of clients on how high cholesterol leads to heart disease. Which explanation regarding high cholesterol is most appropriate?
Correct answer
A
Rationale
The correct answer is A because high cholesterol can lead to atherosclerosis, where cholesterol builds up on vessel walls, narrowing them and reducing blood flow to the heart. This can lead to heart disease. Choice B is incorrect because high cholesterol does not directly damage the heart muscle itself. Choice C is incorrect as high cholesterol does not thicken the blood but rather contributes to plaque formation on vessel walls. Choice D is incorrect as high cholesterol does not interfere with the heart's conduction system, which controls the heart's rhythm.
