1. Which types of lipids must be listed on the food label? Select all that apply.

• A. Total fat
• B. Saturated fat
• C. Trans fat
• D. All of the above

Correct answer: D

Rationale: The correct answer is 'D. All of the above'. This is because, according to regulations, food labels must include the information on total fat, saturated fat, and trans fat. These types of fats are crucial for consumers to monitor, as they can significantly affect heart health. Choices A, B, and C are all correct, but they are only parts of the total information that must be provided. Therefore, the most comprehensive answer is 'D. All of the above'.

2. During early tooth development, vitamin A deficiency leads to enamel hypoplasia and defective dentin formation. Because of its effect on soft tissues and bone, vitamin A contributes to normal spacing of teeth.

• A. Both statements are true.
• B. Both statements are false.
• C. The first statement is true; the second is false.
• D. The first statement is false; the second is true.

Correct answer: A

Rationale: Both statements are true. The effect of vitamin A on the growth of soft tissues and bones naturally extends to the teeth and surrounding structures. Enamel hypoplasia, involving defective enamel matrix and incomplete calcification of enamel and dentin, can be due to vitamin A deficiency. The effect of this vitamin upon surrounding bone directly affects spacing patterns of the teeth within the bone and dentition. Choice A is correct because both statements accurately describe the influence of vitamin A on tooth development. Choices B, C, and D are incorrect as they do not reflect the accuracy of the statements provided.

3. A nurse is providing teaching to the parent of an infant about introducing solid foods. The nurse should recommend that which of the following foods be introduced first?

• A. Strained fruits
• B. Pureed meats
• C. Cooked egg whites
• D. Iron-fortified cereal

Correct answer: D

Rationale: When introducing solid foods to infants, it is recommended to start with iron-fortified cereal as it is easily digestible and a good source of iron, an important nutrient for infants around 6 months of age. Strained fruits are usually introduced later due to their natural sugars. Pureed meats can be introduced after iron-fortified cereals to provide additional protein and iron. Cooked egg whites should be avoided until the infant is at least one year old to reduce the risk of allergies.

4. A client with celiac disease should avoid which of the following?

• A. Quinoa
• B. Barley
• C. Rice
• D. Oats

Correct answer: B

Rationale: The correct answer is B: Barley. Barley contains gluten, which is harmful to individuals with celiac disease. Gluten triggers an immune response in people with celiac disease, damaging the lining of the small intestine. Choices A, C, and D (Quinoa, Rice, and Oats) are gluten-free and safe for individuals with celiac disease to consume.

5. Which enzyme is most essential for the digestion of triglycerides found in butterfat?

• A. Gastric lipase
• B. Pepsin
• C. Mucus
• D. Intrinsic factor

Correct answer: A

Rationale: The correct answer is A: Gastric lipase. Gastric lipase is crucial for the digestion of short- and medium-chain triglycerides, such as those found in butterfat. Pepsin is involved in protein digestion, not lipid digestion. Mucus acts as a protective barrier in the stomach and does not play a direct role in lipid digestion. Intrinsic factor is involved in the absorption of vitamin B12 and is not related to the digestion of triglycerides.
