1. Which vitamin is also known as Niacin?

A. Vitamin B1
B. Vitamin B2
C. Vitamin B3
D. Vitamin B12

Correct answer: C

Rationale: The correct answer is Vitamin B3, also known as Niacin. Niacin is essential for energy metabolism and can help improve cholesterol levels. Vitamin B1 is Thiamine, Vitamin B2 is Riboflavin, and Vitamin B12 is Cobalamin. These vitamins have different functions in the body and are not synonymous with Niacin.

2. How would protein deficiency likely affect dental tissues?

A. Decreased resistance to dental caries
B. Increased tooth size
C. Delayed tooth development
D. Increased enamel mineralization

Correct answer: C

Rationale: Protein deficiency can lead to delayed tooth development as the body may not have enough resources to form teeth properly. This delay can make the teeth more susceptible to dental issues due to incomplete formation. Choices A, B, and D are incorrect. Decreased resistance to dental caries is more related to factors like poor oral hygiene and sugary diets, increased tooth size is not a common effect of protein deficiency on dental tissues, and increased enamel mineralization is not typically associated with protein deficiency.

3. A nurse is providing MyPlate education to a client newly diagnosed with diabetes mellitus. Which plate chosen by the client indicates the teaching was effective, according to the MyPlate guidelines?

A. 1/2 of the plate is filled with carbohydrate foods, 1/4 filled with protein foods, and 1/4 filled with fruits and vegetables
B. 1/2 of the plate is filled with protein foods, 1/4 filled with carbohydrates, and 1/4 filled with non-starchy vegetables
C. 1/2 of the plate is filled with carbohydrates, 1/4 filled with protein foods, and 1/4 filled with non-starchy vegetables
D. 1/2 of the plate is filled with non-starchy vegetables, 1/4 filled with protein foods, and 1/4 filled with carbohydrate foods

Correct answer: D

Rationale: The correct answer is D. This option reflects the MyPlate guidelines for managing diabetes effectively. In diabetes management, it is essential to focus on non-starchy vegetables, appropriate protein portions, and controlled carbohydrate intake. Option A places too much emphasis on carbohydrates, which may not be suitable for diabetes. Option B swaps the proportions of protein and carbohydrates, which is not in line with the recommended distribution. Option C places too much emphasis on carbohydrates and lacks the emphasis on non-starchy vegetables, making it less suitable for diabetes management.

4. A nurse is reinforcing dietary teaching with a client who has vitamin A deficiency. Which of the following food choices should the nurse recommend as the best source of vitamin A?

A. 1 small baked sweet potato
B. 1 cup avocado
C. 1 cup green beans
D. 1 large apple

Correct answer: A

Rationale: The correct answer is A. Sweet potatoes are rich in beta-carotene, which the body converts into vitamin A, essential for vision and immune function. Avocado (choice B) is a good source of healthy fats but not high in vitamin A. Green beans (choice C) are nutritious but not a significant source of vitamin A. Apples (choice D) are low in vitamin A compared to sweet potatoes.

5. What is the term for intestinal wounds associated with Crohn's disease that develop in different areas in the intestine, with normal tissue separating affected regions?

A. Skip lesions
B. Fistulas
C. Fissures
D. Loop ulcerations

Correct answer: A

Rationale: Skip lesions are typical characteristics of Crohn's disease, where patches of diseased intestine are interspersed with areas of healthy tissue. This is why option A is the correct answer. Option B, fistulas, are abnormal connections between two body parts, which is not what the question is describing. Option C, fissures, are small tears in the lining of the anus, which also do not fit the description in the question. Option D, loop ulcerations, is not a recognized medical term, making it an incorrect choice.
