Correct Answer is C

Explanation

Choice A rationale

The small intestine is where nutrients are absorbed, but it is not where vitamin D is activated. Vitamin D is first converted in the liver and then activated in the kidneys to promote calcium absorption.

Choice B rationale

This is incorrect because vitamin D is activated into a form that promotes calcium absorption. The active form is crucial for maintaining calcium and phosphate levels in the blood.

Choice C rationale

The kidneys play a significant role in converting vitamin D to its active form, calcitriol. This activated form is essential for the absorption of calcium in the intestines.

Choice D rationale

The large intestine is involved in water absorption and waste formation but not in the activation of vitamin D. The activation process primarily occurs in the kidneys and liver. .

A. Decrease in sitosterol and serum cholesterol. B. Decrease in campesterol and LDL levels. C. Decrease in serum cholesterol and low-density lipoprotein (LDL) levels. D. Decrease in serum cholesterol only.

Correct Answer is C

Explanation

Choice A rationale

Atorvastatin (Lipitor) does not decrease sitosterol. It mainly targets serum cholesterol and LDL levels to reduce cardiovascular risks.

Choice B rationale

Atorvastatin does not decrease campesterol. Its primary effect is on serum cholesterol and LDL levels, aiming to lower the risk of heart disease.

Choice C rationale

Atorvastatin effectively decreases serum cholesterol and LDL levels, which are the primary targets for reducing cardiovascular risks in patients with high cholesterol.

Choice D rationale

Atorvastatin lowers both serum cholesterol and LDL levels, not just serum cholesterol, making it effective in reducing overall cardiovascular risk.
