Correct Answer is A

Explanation

Choice A rationale

Ineffective health maintenance is appropriate due to the patient's inability to provide names and purposes of medications, indicating insufficient knowledge of their regimen.

Choice B rationale

Noncompliance implies intentional refusal of medication, which is not evident here as the patient is unaware rather than refusing.

Choice C rationale

Acute confusion is not indicated as the patient appears oriented and not disoriented.

Choice D rationale

Risk-prone health behavior is not appropriate as it suggests engagement in harmful activities, which is not described.

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.
