1. A weight reduction regimen calls for a daily intake of 1400 kilocalories, which includes 30 grams of fat. What percentage of the total energy is contributed by fat?

• A. 8.50%
• B. 15.00%
• C. 19.00%
• D. 25.50%

Correct answer: C

Rationale: To calculate the percentage of total energy contributed by fat, first determine the energy from fat by multiplying the fat amount (30g) by the energy density of fat (9 kcal/g), which equals 270 kcal. Then, divide the energy from fat (270 kcal) by the total energy intake (1400 kcal) and multiply by 100 to find the percentage: (270 kcal / 1400 kcal) * 100 = 19.29% ≈ 19.00%. Therefore, fat contributes approximately 19% of the total energy in the diet. Choice A (8.50%) is too low, while choices B (15.00%) and D (25.50%) are incorrect calculations based on the given information.

2. Which nutrient is classified as a micronutrient?

• A. minerals
• B. proteins
• C. alcohols
• D. carbohydrates

Correct answer: A

Rationale: The correct answer is minerals. Micronutrients are required by the body in smaller amounts compared to macronutrients like proteins and carbohydrates. Proteins are macronutrients necessary for growth and repair, not classified as micronutrients. Alcohols and carbohydrates are not classified as micronutrients either.

3. In what units are energy measurements expressed by most scientists and nutritionists outside the United States?

• A. newtons
• B. liters
• C. kilojoules
• D. kilocalories

Correct answer: C

Rationale: Kilojoules are the standard units of energy used by most scientists and nutritionists worldwide. Newtons are units of force, liters are units of volume, and kilocalories are more commonly used in the United States but not as widely adopted internationally for energy measurements. Therefore, the correct answer is 'kilojoules.'

4. What is the appropriate intervention for a child with an undescended testicle?

• A. Wait until puberty
• B. Perform an orchidopexy
• C. Administer hormone therapy
• D. Increase physical activity

Correct answer: B

Rationale: The appropriate intervention for a child with an undescended testicle is to perform an orchidopexy. This surgical procedure is recommended if the testicle has not descended naturally within the first year of life. Waiting until puberty is not advised as early intervention is crucial for optimal outcomes. Administering hormone therapy is not the first-line treatment for an undescended testicle and is typically not recommended. Increasing physical activity does not address the underlying issue of an undescended testicle and is not a suitable intervention.

5. What does the term 'essential nutrient' refer to?

• A. A nutrient that can be synthesized by the body.
• B. A nutrient that is required for proper body functioning.
• C. A nutrient that must be obtained from the diet because the body cannot produce it.
• D. A nutrient that can be stored in the body for long periods.

Correct answer: C

Rationale: The correct answer is C. An essential nutrient is a substance that is necessary for normal body functioning but cannot be synthesized in adequate amounts by the body, therefore it must be obtained from the diet. Choices A, B, and D are incorrect because essential nutrients are not synthesized by the body, they are necessary for body functioning, and they are not typically stored in the body for long periods.
