1. For a healthy person, what percentage of daily calories should be supplied by protein?
- A. 5% to 10%.
- B. 10% to 35%.
- C. more than 25%.
- D. more than 35%.
Correct answer: B
Rationale: The correct answer is B: 10% to 35%. For a healthy person, it is recommended that 10% to 35% of their daily caloric intake should come from protein. This range ensures an adequate intake of protein for various bodily functions without overdoing it. Choices A, C, and D are incorrect because they suggest percentages either below the recommended range (A, C) or exceeding it (D), which could lead to nutritional imbalances or health issues.
2. The primary responsibility for nutrition care of people in the community belongs to the:
- A. community physician.
- B. public health nurse.
- C. public health nutritionist.
- D. registered dietitian.
Correct answer: C
Rationale: Public health nutritionists work within communities to ensure that populations have access to nutritional resources. They focus on promoting good nutrition, developing programs, and educating the public about healthy eating habits. While community physicians, public health nurses, and registered dietitians may also play roles in promoting nutrition in the community, the primary responsibility for nutrition care typically falls under the purview of public health nutritionists.
3. Exchange Lists for Meal Planning group foods that are equivalent in their:
- A. weight.
- B. serving size.
- C. micronutrient content.
- D. macronutrient content.
Correct answer: D
Rationale: The Exchange Lists for Meal Planning categorize foods based on their macronutrient content, such as carbohydrate, protein, and fat. These lists help individuals make food choices while ensuring similar amounts of macronutrients are consumed. Therefore, the correct answer is D. Choices A, B, and C are incorrect because Exchange Lists focus on macronutrient content, not weight, serving size, or micronutrient content.
4. A physical science that contributes to understanding how nutrition relates to health and well-being is:
- A. anatomy
- B. biochemistry
- C. physics
- D. pharmacology
Correct answer: B
Rationale: Biochemistry is the correct answer because it focuses on understanding the chemical processes related to nutrition and how nutrients affect the body. Anatomy (choice A) primarily deals with the structure of organisms, not the chemical processes of nutrition. Physics (choice C) deals with energy and matter, not specifically related to nutrition. Pharmacology (choice D) focuses on drugs and their interactions with the body, not directly related to nutrition and its effects on health.
5. Which of the following provides the best source of nutrients?
- A. specific food combinations.
- B. a variety of foods.
- C. individual foods.
- D. a variety of food supplements.
Correct answer: B
Rationale: A variety of foods is the best source of nutrients because it ensures a balanced intake of all essential nutrients required by the body. Option A, specific food combinations, may not provide all necessary nutrients as relying on only a few types of food may lead to deficiencies. Option C, individual foods, also may not provide a complete range of nutrients necessary for overall health. Option D, a variety of food supplements, is not the best source of nutrients as whole foods are generally more beneficial due to their natural nutrient composition and bioavailability.
