The patient asks the nurse what atorvastatin (Lipitor) newly prescribed will do. What's the expected outcome the nurse will describe?
Decrease in sitosterol and serum cholesterol.
Decrease in campesterol and LDL levels.
Decrease in serum cholesterol and low-density lipoprotein (LDL) levels.
Decrease in serum cholesterol only.
The Correct Answer is C
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.

Correct Answer is B
Explanation
Choice A rationale
Thiazide diuretics do not block the sodium pump. They act primarily on the distal convoluted tubule in the kidneys.
Choice B rationale
Thiazide diuretics block the chloride pump in the distal convoluted tubule, preventing the reabsorption of sodium and chloride, leading to increased urine output and decreased blood pressure.
Choice C rationale
Thiazide diuretics do not block the carbonic anhydrase pump. This action is associated with carbonic anhydrase inhibitors.
Choice D rationale
Thiazide diuretics do not block the potassium pump. They can cause potassium loss as a side effect, but this is not their primary mechanism of action.
Correct Answer is D
Explanation
Choice A rationale
Itching and rash are not common adverse effects associated with calcium-channel blockers. They are more commonly related to other classes of medications.
Choice B rationale
Hypertension and tachycardia are not typical adverse effects of calcium-channel blockers. These medications are usually prescribed to treat hypertension and can actually cause a reduction in heart rate.
Choice C rationale
Nausea and diarrhea are possible side effects of many medications, but they are not specific adverse effects commonly linked to calcium-channel blockers.
Choice D rationale
Headache and dizziness are common adverse effects of calcium-channel blockers. These medications can cause vasodilation, leading to headaches and a decrease in blood pressure, which may result in dizziness, especially when standing up quickly. .
