1. Health practitioners evaluate disease progression in HIV-infected patients by measuring the concentrations of helper T cells and circulating virus, called _____.

Correct answer: D

Rationale: The viral load is the measure of the amount of circulating virus in the blood and is used to evaluate the progression of HIV infection.

2. Each statement regarding the correlation between vitamin D and sun exposure is accurate, except one. Which is the exception?

Correct answer: C

Rationale: While UV radiation can penetrate uncovered skin and convert a precursor of vitamin D to vitamin D3, sunscreen does block the formation of vitamin D3. Sunscreen is recommended by dermatologists to prevent sunburn and reduce the risk of skin cancer. The other choices are correct: the body can produce sufficient vitamin D from sunlight, UV radiation can convert a precursor of vitamin D to vitamin D3, and skin generally produces less vitamin D as a person ages.

3. A nurse is planning to teach a client about a low-potassium diet. Which of the following foods should the nurse instruct the client to avoid?

Correct answer: D

Rationale: Orange juice is high in potassium and should be avoided in a low-potassium diet. Butter, poultry, and yogurt are low-potassium food choices and can be included in a low-potassium diet. Poultry is a good source of lean protein, yogurt is a good source of calcium and protein, and butter is low in potassium. Therefore, the nurse should instruct the client to avoid orange juice as it is high in potassium, which is not suitable for a low-potassium diet.

4. Skin care around the stoma is critical. Which of the following is not indicated as a skin care barriers?

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.

5. Which food would benefit an anemic patient by increasing their intake?

Correct answer: A

Rationale: An anemic patient would benefit from increasing their intake of beef. Beef is an excellent source of heme iron, which is critical for treating anemia. Heme iron is absorbed more readily by the body compared to non-heme iron found in plant-based foods. Apples and white bread, while healthy, do not contain significant amounts of heme iron. Fish, although it does contain iron, it's non-heme iron, which is not as efficiently absorbed by the body as heme iron, hence less effective in treating anemia.
