1. Which of the following is NOT a risk factor for developing atherosclerosis?
- A. High blood pressure
- B. High levels of LDL cholesterol
- C. Regular physical activity
- D. Smoking
Correct answer: C
Rationale: Regular physical activity is NOT a risk factor for developing atherosclerosis. In fact, engaging in regular physical activity can help reduce the risk of developing atherosclerosis by improving cardiovascular health, lowering blood pressure, and reducing LDL cholesterol levels. High blood pressure, high levels of LDL cholesterol, and smoking are all known risk factors for atherosclerosis. High blood pressure can damage blood vessels, making them more susceptible to plaque buildup. High levels of LDL cholesterol can lead to the accumulation of plaque in the arteries, narrowing the passageways and increasing the risk of atherosclerosis. Smoking is harmful to blood vessels, promoting inflammation and the formation of plaque. Therefore, regular physical activity is actually a protective factor against atherosclerosis rather than a risk factor.

Rationale: The correct answer is B: Edema. Edema is the condition characterized by swelling caused by a buildup of lymph fluid in the body's tissues. Anemia (A) is a condition characterized by a lack of healthy red blood cells, not swelling. Hypertension (C) is high blood pressure, which does not directly cause swelling. Diabetes (D) is a metabolic disorder affecting blood sugar levels and does not directly lead to lymph fluid buildup and swelling.
