1. What is the main purpose of Recommended Dietary Allowances (RDAs)?

• A. To provide guidelines for nutrient intakes that meet the needs of most healthy people.
• B. To specify the minimum amount of nutrients required for survival.
• C. To establish maximum safe levels of nutrient intakes.
• D. To recommend specific nutrient intake levels to prevent chronic diseases.

Correct answer: A

Rationale: The main purpose of Recommended Dietary Allowances (RDAs) is to provide guidelines for nutrient intakes that meet the needs of most healthy people. Choice B is incorrect because RDAs aim beyond just survival requirements. Choice C is incorrect because establishing maximum safe levels is the role of Tolerable Upper Intake Levels (ULs). Choice D is incorrect because preventing chronic diseases is more associated with Dietary Reference Intakes (DRIs) like Adequate Intakes (AIs) and Tolerable Upper Intake Levels (ULs). Therefore, the correct answer is A.

2. Why would a person who eats a bowl of oatmeal for breakfast every day most likely be making a food choice based on ___?

• A. habit
• B. availability
• C. body image
• D. environmental concerns

Correct answer: A

Rationale: The correct answer is A: habit. Eating the same food regularly often stems from habit, which is a behavior that is repeated regularly and tends to occur subconsciously. Choice B, availability, is incorrect as it refers to the accessibility of a particular food rather than the frequency of consumption. Choice C, body image, is also incorrect as this term relates to how one perceives their own body rather than their food choices. Choice D, environmental concerns, is unrelated to the scenario provided, which is about the frequency of choosing oatmeal for breakfast.

3. Which of the following is an example of a macronutrient?

• A. Vitamin C
• B. Iron
• C. Calcium
• D. Fiber

Correct answer: D

Rationale: The correct answer is D: Fiber. Macronutrients are nutrients required by the body in larger amounts, and they include carbohydrates, proteins, and fats. Fiber is a type of carbohydrate that falls under this category. Vitamin C (choice A) is a water-soluble vitamin, Iron (choice B) is a mineral, and Calcium (choice C) is also a mineral, not a macronutrient. Therefore, Fiber is the only macronutrient listed in the choices.

4. 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.

5. What should be included in the medical management of a sickle cell crisis?

• A. Information for parents on home care
• B. Adequate hydration and pain management
• C. Pain management and iron supplements
• D. Adequate oxygenation and factor VIII

Correct answer: B

Rationale: The correct answer is B: Adequate hydration and pain management. During a sickle cell crisis, it is essential to provide hydration to prevent vaso-occlusive events and manage pain effectively with analgesics. Adequate hydration helps maintain blood flow and prevent further sickling of red blood cells. Pain management is crucial to alleviate the severe pain associated with sickle cell crises. Options A, C, and D are incorrect. Providing information for parents on home care (Option A) may be important for ongoing management but is not specific to an acute crisis. Iron supplements (Option C) are not typically indicated during a sickle cell crisis. Adequate oxygenation and factor VIII (Option D) are not primary interventions for managing a sickle cell crisis; instead, oxygen therapy may be considered in severe cases, and factor VIII is not a standard treatment for sickle cell disease.
