1. What is the most significant dietary influence on the development of dental caries?

• A. Carbohydrates
• B. Vitamins
• C. Minerals
• D. Fats

Correct answer: A

Rationale: The correct answer is A: Carbohydrates. Carbohydrates, especially fermentable sugars, are the most significant dietary factor in the development of dental caries. When these sugars are consumed, they can be fermented by bacteria in the mouth, leading to the production of acids. These acids lower the pH in the mouth, creating an acidic environment that promotes demineralization of the tooth enamel, ultimately causing dental caries. Choices B, C, and D are incorrect because while vitamins and minerals are important for overall health, they do not have the same direct impact on the development of dental caries as fermentable carbohydrates do. Fats, on the other hand, do not play a significant role in the development of dental caries.

2. Select all that apply. To lower LDL levels, you should:

• A. consume minimal amounts of hydrogenated and saturated fats
• B. consume more insoluble fibers than soluble fibers
• C. consume alcohol in moderate levels
• D. engage in regular physical activity

Correct answer: A

Rationale: To lower LDL levels, reducing intake of hydrogenated (trans) and saturated fats is crucial, as these types of fats can raise LDL cholesterol in the blood. Choice B is incorrect because both soluble and insoluble fibers can help lower LDL levels. Choice C is incorrect as excessive alcohol consumption can lead to increased LDL levels. Choice D, engaging in regular physical activity, can help raise HDL (good) cholesterol levels but is not directly related to lowering LDL levels.

3. Which breakfast items indicate an understanding of foods high in antioxidants A and C?

• A. Fried eggs, sausage, and whole wheat toast
• B. Oatmeal with blueberries and coffee
• C. Cereal with strawberries and low-fat milk
• D. Hard-boiled eggs, cantaloupe, and orange juice

Correct answer: D

Rationale: The correct answer is D: Hard-boiled eggs, cantaloupe, and orange juice. Cantaloupe and orange juice are rich in vitamins A and C, which are known for their antioxidant properties. Choice A is incorrect because fried eggs, sausage, and whole wheat toast do not contain high levels of antioxidants A and C. Choice B is incorrect because, while blueberries are high in antioxidants, coffee does not provide significant amounts of vitamins A and C. Choice C is incorrect because, although strawberries are a good source of vitamin C, low-fat milk does not contribute significantly to vitamins A and C.

4. A nurse is reinforcing dietary teaching with a client who has vitamin A deficiency. Which of the following food choices should the nurse recommend as the best source of vitamin A?

• A. 1 small baked sweet potato
• B. 1 cup avocado
• C. 1 cup green beans
• D. 1 large apple

Correct answer: A

Rationale: The correct answer is A. Sweet potatoes are rich in beta-carotene, which the body converts into vitamin A, essential for vision and immune function. Avocado (choice B) is a good source of healthy fats but not high in vitamin A. Green beans (choice C) are nutritious but not a significant source of vitamin A. Apples (choice D) are low in vitamin A compared to sweet potatoes.

5. Individuals who use antiretroviral drugs frequently develop insulin resistance and _____.

• A. hypertension
• B. hypothyroidism
• C. hyperlipidemia
• D. fluid retention

Correct answer: C

Rationale: The correct answer is C: hyperlipidemia. Antiretroviral drugs can often lead to elevated lipid levels (hyperlipidemia), which is a common side effect of this therapy. This increase in lipids can contribute to cardiovascular risk. Hypertension (choice A) is not typically associated with antiretroviral drug use. Hypothyroidism (choice B) and fluid retention (choice D) are also not commonly linked to antiretroviral therapy.
