What is the difference between atherosclerosis and arteriosclerosis?

Choice A reason: Atherosclerosis involves plaque buildup, not loss of elasticity, while arteriosclerosis is the general hardening of arteries, including elasticity loss. This reverses the definitions, making it incorrect, as the nurse must clarify that atherosclerosis is plaque-related and arteriosclerosis is broader vessel hardening. Choice B reason: Both atherosclerosis and arteriosclerosis affect arteries, not veins. Atherosclerosis involves plaque, while arteriosclerosis includes any arterial hardening. This is incorrect, as it misidentifies the affected vessels, requiring correction to focus on arterial pathology for both conditions. Choice C reason: Atherosclerosis is the buildup of plaque in arteries, causing narrowing, while arteriosclerosis is the general loss of arterial elasticity and hardening, including atherosclerosis. This is the correct distinction, accurately describing the difference in their pathological processes for the nurse’s understanding. Choice D reason: Neither atherosclerosis nor arteriosclerosis is fully reversible, though lifestyle changes can slow progression. This is incorrect, as the distinction lies in plaque buildup (atherosclerosis) versus general hardening (arteriosclerosis), not reversibility, requiring clarification of their chronic nature.
