Correct Answers
1. Which of the following is the primary mechanism of action in the pathophysiology of
atherosclerosis?
• A) Increased platelet aggregation
• B) Endothelial injury and inflammation
• C) Smooth muscle atrophy
• D) Immune cell hyperactivation
Answer: B) Endothelial injury and inflammation
Rationale: Atherosclerosis begins with damage to the endothelial cells, which leads to an
inflammatory response. This results in the
accumulation of lipids, smooth muscle cell proliferation, and the
formation of plaques. Platelet aggregation also plays a role, but the initial event is endothelial
injury.

2. What is the primary effect of aldosterone in the body?
• A) Decreases sodium reabsorption
• B) Increases potassium secretion
• C) Reduces water retention
• D) Stimulates the renin-angiotensin system
Answer: B) Increases potassium secretion
Rationale: Aldosterone acts on the kidneys to increase sodium
reabsorption and potassium excretion. It also contributes to water
retention indirectly by enhancing sodium reabsorption, which in turn
draws water into the bloodstream.
