1. Which foods are the biggest contributors of saturated fats consumed by Americans?

• A. Butter, coconut, and palm oils
• B. Corn oil
• C. Meat and milk
• D. Cheese, pizza, desserts, and chicken

Correct answer: D

Rationale: The correct answer is D: Cheese, pizza, desserts, and chicken. These foods are significant contributors to the intake of saturated fats in the American diet, often found in processed and fast foods. Choices A, B, and C are incorrect because while butter, coconut, and palm oils (A) are sources of saturated fats, they are not the biggest contributors in the American diet. Corn oil (B) is a source of unsaturated fats, and meat and milk (C) contain saturated fats but are not the primary contributors compared to cheese, pizza, desserts, and chicken.

2. Lynn is an older adult who lives alone and has requested advice on how to eat a nutritious diet as cheaply as possible. One useful, practical tip for Lynn might be to _____.

• A. buy just a few pieces of fresh fruit at a time, in different stages of ripeness
• B. choose small boxes of frozen vegetables instead of large bags
• C. purchase pre-sliced or shredded cheese rather than whole pieces
• D. avoid buying certain foods in bulk, such as beans or dried legumes

Correct answer: A

Rationale: Buying a few pieces of fresh fruit at different stages of ripeness ensures that Lynn will have ripe fruit available over several days, reducing waste and cost. Choice B focuses on frozen vegetables but doesn't address the variety and ripeness factor like Choice A. Choice C is about cheese, which may not be as essential for a nutritious diet compared to fresh fruit. Choice D suggests avoiding certain foods in bulk, which might not be as relevant for maintaining a nutritious diet economically as the strategy in Choice A.

3. Metabolic control is especially important for women with gestational diabetes to ensure the infant does not develop:

• A. microsomia
• B. macrosomia
• C. type 1 diabetes
• D. type 2 diabetes

Correct answer: B

Rationale: Metabolic control is crucial for women with gestational diabetes to prevent the development of macrosomia, which is characterized by an abnormally large baby. This condition poses risks such as birth injuries and necessitates careful management of blood sugar levels. Microsomia is not a known term related to this context. Type 1 and type 2 diabetes are not conditions the infant would develop as a result of gestational diabetes in the mother.

4. What physiological role does phosphorus play in the body?

• A. Blood clotting, transmission of nerve impulses, muscle contraction, and relaxation
• B. Calcium homeostasis, structural integrity of heart muscle
• C. No known metabolic function, caries-preventing properties
• D. ATP energy release; metabolism of fats, carbohydrates, proteins; regulates acid-base balance

Correct answer: D

Rationale: The correct answer is D. Phosphorus plays a crucial role in ATP energy release, the metabolism of fats, carbohydrates, and proteins, and regulation of acid-base balance. Choices A, B, and C are incorrect. Phosphorus is not directly involved in blood clotting, transmission of nerve impulses, muscle contraction, or calcium homeostasis. It also has known metabolic functions and is not associated with caries prevention.

5. According to the dietary reference intakes, what percentage of your daily calorie intake should ideally come from carbohydrates?

• A. 10-35%
• B. 20-35%
• C. 40-50%
• D. 45-65%

Correct answer: D

Rationale: Carbohydrates should ideally make up 45-65% of your total daily caloric intake, according to the Dietary Reference Intakes (DRIs). This range provides the necessary energy for bodily functions and activities. Choices A, B, and C are incorrect because they fall outside the recommended range for carbohydrate intake based on the DRIs.
