1. Each of the following is a characteristic of fat, except one. Which is the exception?

• A. 95% of ingested fats are absorbed
• B. Hard fats take longer to digest than soft fats
• C. Fats contribute to palatability and flavor of foods
• D. Cooked fats improve the texture of foods

Correct answer: B

Rationale: The correct answer is B. Hard fats take longer to digest than soft fats because hard fats are solid at body temperature, making them more challenging to break down. Choice A is true as the majority of ingested fats are absorbed. Choice C is correct as fats indeed contribute to the palatability and flavor of foods. Choice D is accurate as cooked fats can enhance the texture of foods.

2. Select all that apply. Which of the following are true about protein digestion?

• A. the end products of protein digestion are amino acids
• B. protein/polypeptides are digested in the large intestine by trypsin
• C. A, D
• D. protein/polypeptides are digested in the stomach by pepsin

Correct answer: C

Rationale: Protein digestion begins in the stomach with the enzyme pepsin, which breaks down proteins into smaller polypeptides. The end products of protein digestion are amino acids.

3. What is the approximate energy value of alcohol?

• A. 3 kcal/g
• B. 7 kcal/g
• C. 10 kcal/g
• D. 25 kcal/g

Correct answer: B

Rationale: The correct answer is B: 7 kcal/g. Alcohol provides approximately 7 kilocalories per gram, making it a significant source of energy or 'empty calories' in the diet that do not contain any nutrients. 'Empty calories' refer to the calorie content without the presence of essential nutrients. Choices A, C, and D are incorrect. The energy values of 3 kcal/g, 10 kcal/g, and 25 kcal/g are not accurate for alcohol; instead, they may pertain to other nutrients such as carbohydrates (approximately 4 kcal/g), fats (approximately 9 kcal/g), and oils (approximately 9 kcal/g).

4. Each of the following is a form of vitamin K, except one. Which is the exception?

• A. Phylloquinone
• B. Tocopherol
• C. Menaquinone
• D. Menadione

Correct answer: B

Rationale: Tocopherol, Choice B, is not a form of vitamin K; it is another name for vitamin E. Phylloquinone (Choice A), menaquinone (Choice C), and menadione (Choice D) are all forms of vitamin K. Phylloquinone is vitamin K1 found in green plants, menaquinone is vitamin K2 produced in the large intestine and found in animal tissues, and menadione is a synthetic form of vitamin K. Therefore, Choice B is the correct answer because it does not belong to the vitamin K group, unlike the other options.

5. Which food is a reliable source of B12 for a pregnant vegan client?

• A. Soybeans
• B. Algae
• C. Fortified soy milk
• D. Sea vegetables

Correct answer: C

Rationale: Fortified soy milk is a reliable source of vitamin B12 for pregnant vegan clients as it is usually enriched with this vitamin. The other options, while nutritious, are not reliable sources of B12 for vegans. Soybeans may not provide enough B12, algae contains B12 analogs that the human body cannot utilize, and the B12 content in sea vegetables can fluctuate, potentially not providing the necessary daily intake.
