1. Each is a physiologic role of vitamin D, except one. Which is the exception?

• A. Hematopoiesis
• B. Cardiac and neuromuscular function
• C. Immune responses
• D. Serum calcium regulation

Correct answer: A

Rationale: The correct answer is A, Hematopoiesis. Vitamin D plays a crucial role in regulating serum calcium levels, which is essential for maintaining cardiac and neuromuscular function. Additionally, vitamin D is involved in modulating immune responses. However, hematopoiesis, the formation of red blood cells, is not a direct physiologic role of vitamin D. Therefore, hematopoiesis is the exception among the listed functions of vitamin D.

2. What laboratory value would be considered a high-risk measure for coronary heart disease assessment?

• A. triglycerides > 150 mg/dL
• B. BMI > 31
• C. LDL cholesterol < 128 mg/dL
• D. blood pressure of 128/82 mmHg

Correct answer: B

Rationale: The correct answer is B: BMI > 31. A BMI over 31 is considered a high-risk factor for coronary heart disease as it indicates obesity, which is strongly linked to cardiovascular issues. Triglycerides > 150 mg/dL (choice A) can contribute to heart disease risk but are not as specific as BMI in assessing overall risk. LDL cholesterol < 128 mg/dL (choice C) is actually a desirable level, indicating lower risk. A blood pressure of 128/82 mmHg (choice D) is within normal range and not a high-risk measure specifically for coronary heart disease.

3. Which food provides a 1-ounce serving of grains for a preschool child?

• A. 1 cup of ready-to-eat cereal flakes
• B. 1⁄2 slice of whole wheat bread
• C. 1⁄2 of a 6-inch flour tortilla
• D. 1 cup of cooked rice

Correct answer: A

Rationale: The correct answer is A: 1 cup of ready-to-eat cereal flakes. For a preschool child, 1 cup of ready-to-eat cereal flakes provides a 1-ounce serving of grains, meeting the requirement. Choice B, 1⁄2 slice of whole wheat bread, is not the correct answer as it does not constitute a 1-ounce serving of grains. Similarly, choice C, 1⁄2 of a 6-inch flour tortilla, does not offer a 1-ounce serving of grains. Choice D, 1 cup of cooked rice, also does not provide a 1-ounce serving of grains for a preschool child, making it an incorrect choice.

4. Which mental health disorder can lead to the erosion of lingual enamel, enlarged parotid glands, palatal bruising, and dentinal hypersensitivity?

• A. Bulimia
• B. Anorexia nervosa
• C. Depression
• D. Schizophrenia

Correct answer: A

Rationale: The correct answer is A: Bulimia. Bulimia involves repeated episodes of binge eating followed by purging, which can lead to the erosion of lingual enamel, enlarged parotid glands, palatal bruising, and dentinal hypersensitivity. This behavior exposes the teeth to stomach acid during purging, causing damage to the enamel. Choices B, C, and D are incorrect because these conditions are not typically associated with the specific oral health issues mentioned in the question.

5. A nurse is caring for a client with a major burn injury and is receiving TPN. Which of the following lab tests is the priority for the nurse to use to confirm the client is receiving adequate nutrition?

• A. Iron
• B. Magnesium
• C. Folic acid
• D. Prealbumin

Correct answer: D

Rationale: Prealbumin is a sensitive indicator of protein status and nutrition, making it a priority for assessing nutritional adequacy in clients receiving TPN. Iron, magnesium, and folic acid levels are important for overall health but do not specifically indicate nutritional adequacy in the context of TPN administration.
