1. How do foods or supplements containing significant amounts of plant sterols help lower LDL cholesterol levels?

Correct answer: D

Rationale: Plant sterols interfere with cholesterol and bile absorption in the intestines. This interference helps lower LDL cholesterol levels by reducing the amount of cholesterol that enters the bloodstream. Choices A, B, and C are incorrect because plant sterols primarily work by interfering with cholesterol and bile absorption, not by reducing cholesterol synthesis, suppressing inflammation, or reducing blood clotting.

2. As the head nurse in the OR, how can you improve the effectiveness of clinical alarm systems?

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.

3. Which two dietary components may help decrease blood cholesterol levels?

Correct answer: A

Rationale: The correct answer is A: Omega-3 fatty acids and soluble fiber. Omega-3 fatty acids are known to reduce triglycerides, while soluble fiber helps to lower LDL cholesterol levels. Both of these components are beneficial in managing blood cholesterol levels. Choice B, short-chain fatty acids and insoluble fiber, is incorrect as they do not have the same cholesterol-lowering effects as omega-3 fatty acids and soluble fiber. Choice C, trans fatty acids and potassium, is incorrect as trans fatty acids can raise LDL cholesterol levels and increase the risk of heart disease. Choice D, cis fatty acids and calcium, is incorrect as cis fatty acids are common in natural fats and do not specifically help in reducing blood cholesterol levels.

4. Which vitamin is also known as Niacin?

Correct answer: C

Rationale: The correct answer is Vitamin B3, also known as Niacin. Niacin is essential for energy metabolism and can help improve cholesterol levels. Vitamin B1 is Thiamine, Vitamin B2 is Riboflavin, and Vitamin B12 is Cobalamin. These vitamins have different functions in the body and are not synonymous with Niacin.

5. Nutrients that may help decrease high blood pressure levels include:

Correct answer: C

Rationale: Calcium and potassium play vital roles in regulating blood pressure, with potassium helping to balance the negative effects of sodium.
