1. Maternal malnutrition at a critical period of development may have lifelong effects on an individual's pattern of genetic expression and on the tendency to develop obesity, which is a concept known as _____.
- A. genetic determination
- B. metabolic tolerance
- C. chromosomal influence
- D. fetal programming

2. Why might patients with periodontal disease require increased protein intake?
- A. Both the statement and the reason are correct and related
- B. Both the statement and the reason are correct but are not related
- C. The statement is correct, but the reason is not correct
- D. The statement is not correct, but the reason is correct
Correct answer: A
Rationale: Patients with periodontal disease may require increased protein intake due to the physiological response to inflammation and infection, which can negatively impact protein synthesis. Protein is essential for wound healing and tissue repair, and an infection can increase the body's protein requirements. Therefore, ensuring an adequate protein intake is particularly important for these patients. Choice A is correct because the statement and reason are both accurate and directly related to each other, supporting the increased protein needs in patients with periodontal disease. Choices B, C, and D are incorrect as they do not accurately assess the relationship between the statement and the reason provided in the question.
3. An estimated _____ percent of persons in the United States who have HIV infection are unaware that they are infected.
- A. 4%
- B. 21%
- C. 34%
- D. 49%
Correct answer: B
Rationale: The correct answer is B: '21%'. Approximately 21% of persons in the United States who have HIV infection are unaware that they are infected. This percentage represents a significant portion of individuals who are not aware of their HIV status, highlighting the importance of increased testing and awareness campaigns. Choices A, C, and D are incorrect as they do not align with the estimated percentage provided in the context.
4. Intrinsic factor from the stomach is needed for the absorption of which vitamin?
- A. vitamin B12
- B. folate
- C. niacin
- D. vitamin B6
Correct answer: A
Rationale: The correct answer is A: vitamin B12. Intrinsic factor is a glycoprotein produced by the stomach that is necessary for the absorption of vitamin B12 in the small intestine. Vitamin B12 binds to intrinsic factor in the stomach, forming a complex that is then absorbed in the ileum. This absorption process is crucial for preventing vitamin B12 deficiency. Choices B, C, and D are incorrect because they do not require intrinsic factor for absorption. Folate is absorbed in the small intestine through a different mechanism, niacin can be absorbed in the small intestine without the need for intrinsic factor, and vitamin B6 does not rely on intrinsic factor for absorption.
5. A nurse is reviewing the laboratory results for a client who has a history of atherosclerosis and notes elevated cholesterol levels. Which of the following statements by the client indicates the nurse should plan follow-up teaching on a low-cholesterol diet?
- A. "I flavor my meat with lemon juice."?
- B. "I eat two eggs for breakfast each morning."?
- C. "I cook my food with canola oil."?
- D. "I take an omega-3 supplement daily."?
Correct answer: B
Rationale: The correct answer is B. Eggs are high in cholesterol, so someone with elevated cholesterol levels, especially with a history of atherosclerosis, should be cautious about egg consumption. Choices A, C, and D are not as concerning for cholesterol levels. Lemon juice, canola oil, and omega-3 supplements do not significantly impact cholesterol levels compared to consuming eggs regularly.
