Which nutrient deficiency are people who regularly take prescription drugs such as steroids and diuretics at risk for?
- A. Potassium
- B. Selenium
- C. Iodine
- D. Chloride
Correct Answer: A
Rationale: Regular intake of prescription drugs like steroids and diuretics can lead to the loss of potassium in the body, causing a condition known as hypokalemia. Therefore, people on these medications require careful monitoring and often need potassium supplementation to prevent this deficiency. The other options, selenium, iodine, and chloride, are incorrect because there is no specific link between their deficiency and the regular use of steroids and diuretics.

Which risk factors increase the risk of atherosclerosis?
- A. Exercise
- B. Excessive sun exposure
- C. Insufficient vaccinations
- D. Smoking
Correct Answer: D
Rationale: Smoking is a major risk factor for atherosclerosis. It significantly contributes to the buildup of plaque in the arteries and thereby increases the risk of cardiovascular diseases. On the other hand, exercise is generally beneficial for cardiovascular health and is not a risk factor for atherosclerosis. Excessive sun exposure and insufficient vaccinations have no established links to atherosclerosis, making them incorrect options for this question.
Why is atherosclerosis dangerous to arterial function?
- A. It diminishes central circulation
- B. It causes decreased blood pressure on artery walls
- C. It narrows the arterial lumen so a clot can easily block it
- D. It increases arterial elasticity
Correct Answer: C
Rationale: Atherosclerosis is dangerous to arterial function because it narrows the arterial lumen, increasing the risk of a clot completely blocking the blood flow. This can lead to severe cardiovascular events such as heart attacks or strokes. Choice A is incorrect since atherosclerosis does not primarily diminish central circulation, but rather, it impedes local blood flow where the plaque is present. Choice B is also incorrect as atherosclerosis increases the pressure on artery walls due to the narrowed space for blood flow, not decrease it. Lastly, choice D is incorrect as atherosclerosis causes the arteries to lose their elasticity, not increase it.
