1. Each of the following is a fat-soluble vitamin except for one. Which is the exception?

• A. Vitamin A
• B. Vitamin C
• C. Vitamin D
• D. Vitamin K

Correct answer: B

Rationale: The correct answer is B, Vitamin C. Vitamin C is a water-soluble vitamin, not fat-soluble. Fat-soluble vitamins are Vitamins A, D, E, and K. These vitamins are stored in the body's fat tissues and liver, unlike water-soluble vitamins which are not stored and are eliminated in urine, making them less likely to reach toxic levels.

2. A patient has begun taking furosemide to manage heart failure. What food should the nurse recommend that the patient consume frequently while taking this drug?

• A. legumes
• B. cabbage
• C. peanut butter
• D. bananas

Correct answer: D

Rationale: Furosemide is a diuretic that can lead to potassium loss; therefore, it is recommended that patients consume potassium-rich foods like bananas to prevent hypokalemia.

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

• A. magnesium and sodium
• B. protein and monounsaturated fat
• C. calcium and potassium
• D. dietary fiber and plant sterols

Correct answer: C

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

4. Reducing the amount of trans fat in the diet is an effective method of decreasing the risk of CHD. Which food is most likely a source of trans fat?

• A. hot dogs
• B. whole milk
• C. fatty fish
• D. potato chips

Correct answer: D

Rationale: The correct answer is D: potato chips. Potato chips, especially when fried in hydrogenated oils, are a common source of trans fats, which are linked to an increased risk of coronary heart disease (CHD). Hot dogs (choice A) can also contain trans fats if made with processed meats and added fats. Whole milk (choice B) and fatty fish (choice C) do not typically contain trans fats, making them less likely sources compared to potato chips.

5. What is the major diet-derived antioxidant found in cell membranes?

• A. B12
• B. beta-carotene
• C. vitamin E
• D. vitamin A

Correct answer: C

Rationale: The correct answer is vitamin E. Vitamin E is the major antioxidant found in cell membranes, where it plays a crucial role in protecting them from oxidative damage. Although B12, beta-carotene, and vitamin A are important nutrients with specific functions in the body, they are not the primary antioxidants found in cell membranes. Vitamin E specifically localizes in cell membranes to neutralize free radicals and prevent lipid peroxidation, making it an essential antioxidant for cellular health.
