1. How is resistant starch digested in the colon?

• A. bacterial fermentation.
• B. pancreatic amylase.
• C. hydrochloric acid.
• D. villi and microvilli.

Correct answer: A

Rationale: In the colon, resistant starch is digested by bacterial fermentation. The correct answer is A. During this process, short-chain fatty acids are produced. Pancreatic amylase, as mentioned in choice B, is responsible for breaking down starch in the small intestine, not in the colon. Choice C, hydrochloric acid, functions in the stomach to aid in the digestion of proteins, not starch. Villi and microvilli, as stated in choice D, are structures in the small intestine that absorb nutrients; they do not participate in the digestion of resistant starch in the colon.

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. People with phenylketonuria should avoid foods made with which nonnutritive sweetener?

• A. acesulfame-K
• B. aspartame
• C. saccharin
• D. sucralose

Correct answer: B

Rationale: People with phenylketonuria should avoid aspartame because it contains phenylalanine, which they cannot metabolize. Acesulfame-K, saccharin, and sucralose do not contain phenylalanine and are safe for individuals with phenylketonuria. Therefore, the correct answer is B. Acesulfame-K, saccharin, and sucralose are incorrect choices because they do not pose a risk for individuals with phenylketonuria due to the absence of phenylalanine in their composition.

4. In an analysis of the amino acid composition of foods, the amino acid occurring in the smallest amount is called:

• A. indispensable.
• B. dispensable.
• C. complementary.
• D. limiting.

Correct answer: D

Rationale: The correct answer is D, 'limiting.' In the analysis of the amino acid composition of foods, the amino acid that occurs in the smallest amount is referred to as the limiting amino acid. This term is used because when one essential amino acid is deficient, it limits the synthesis of proteins, making it crucial in determining protein quality. Choices A, B, and C are incorrect. 'Indispensable' and 'dispensable' refer to the essentiality of amino acids, and 'complementary' does not describe the concept of the amino acid occurring in the smallest amount.

5. 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.
