1. Which of the following statements is false?

• A. People with a vitamin K deficiency experience increased clotting time
• B. The major function of vitamin E is promoting vision
• C. Vitamin D functions as a hormone
• D. Rich sources of beta-carotene include carrots, sweet potatoes, and butternut squash

Correct answer: B

Rationale: The statement that the major function of vitamin E is promoting vision is incorrect. Vitamin E primarily acts as an antioxidant, protecting cells from oxidative damage. Its role is not primarily related to vision, which is a major function of vitamin A. On the other hand, the other options are true. Vitamin K deficiency does indeed lead to increased clotting time, vitamin D functions as a hormone, and carrots, sweet potatoes, and butternut squash are rich sources of beta-carotene.

2. What is a disadvantage of using a food frequency questionnaire?

• A. It does not influence the food choices of the consumer
• B. It is not affected by seasonal changes in the diet
• C. It is not effective for monitoring short-term changes in food intake
• D. It does not take too long to obtain the results

Correct answer: C

Rationale: Option C is correct because a food frequency questionnaire is designed to capture a person's typical food intake over an extended period and is not suitable for monitoring short-term changes in diet. The questionnaire's purpose is to provide insights into long-term dietary patterns rather than immediate changes. Option A is incorrect as the questionnaire does not influence food choices; it merely records them. Option B is also incorrect because, while seasonal changes can impact food availability and thereby influence diet, the questionnaire itself is not affected by these changes. Lastly, option D is incorrect as the time to obtain results from a food frequency questionnaire would depend on the respondent's speed and accuracy rather than being intrinsically linked to the questionnaire.

3. When should a newborn transition to whole milk according to dietary teaching for breastfeeding parents?

• A. 6 months
• B. 8 months
• C. 10 months
• D. 12 months

Correct answer: D

Rationale: Breast milk or formula should be the primary source of nutrition for infants up to around 1 year of age. The transition to whole cow's milk is recommended at 12 months of age, not earlier. Introducing whole milk before 12 months can lead to digestive issues and nutrient deficiencies. Therefore, choices A, B, and C are incorrect as they suggest transitioning to whole milk before the recommended age of 12 months.

4. Which of the following converts starch to disaccharides, and this reaction occurs in the _____?

• A. pancreatic amylases, small intestine
• B. brush border enzymes, small intestine
• C. luminal enzymes, large intestine
• D. pancreatic amylases, pancreas

Correct answer: A

Rationale: The correct answer is A. Pancreatic amylases break down starch into disaccharides in the small intestine. This process occurs in the small intestine, not the large intestine or pancreas. Brush border enzymes act on disaccharides to break them down into monosaccharides, while luminal enzymes are not specifically involved in the conversion of starch to disaccharides.

5. Proteolytic enzymes are most likely to break down which food type?

• A. Carbohydrates
• B. Proteins
• C. Fats
• D. Lipids

Correct answer: B

Rationale: Proteolytic enzymes target proteins for breakdown into amino acids. Carbohydrates are broken down by enzymes like amylase, while fats are broken down by lipase. Lipids, which include fats, are not specifically targeted by proteolytic enzymes.
