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

Correct answer: D

Rationale: Fetal programming refers to the concept that maternal nutrition during critical periods of development can have long-term effects on an individual's health and risk of diseases like obesity.

2. James wants to know the recommended intake for iron for his gender and age. Which of the following would provide the best answer for James?

• A. EAR
• B. UL
• C. RDA
• D. DV

Correct answer: C

Rationale: The Recommended Dietary Allowance (RDA) is the correct answer for James because it provides the daily intake level that meets the nutrient needs of most healthy individuals in a specific age and gender group. Choice A, EAR (Estimated Average Requirement), represents the average daily nutrient intake level estimated to meet the requirement of half the healthy individuals in a particular life stage and gender group. Choice B, UL (Tolerable Upper Intake Level), is the maximum daily intake unlikely to cause adverse health effects. Choice D, DV (Daily Value), is a general guide used for food labeling that represents how much a nutrient in a serving of food contributes to a daily diet based on a 2000-calorie daily intake.

3. What is a major constituent of cell membranes?

• A. cholesterol
• B. phospholipid
• C. saturated
• D. triglyceride

Correct answer: B

Rationale: Phospholipids are a major component of cell membranes, providing structural integrity and facilitating cell signaling. Cholesterol (choice A) is also present in cell membranes but in smaller amounts and plays a different role. Saturated (choice C) and triglyceride (choice D) are not major constituents of cell membranes.

4. What describes a criterion used to diagnose diabetes?

• A. a plasma glucose concentration of 100 mg/dL or higher after a fast of at least 12 hours
• B. a casual blood sample of 200 mg/dL or higher in a person with classic symptoms
• C. a plasma glucose concentration measured two hours after a 200-gram glucose load is 400 mg/dL or higher
• D. a HbA1C higher than 5 percent

Correct answer: B

Rationale: A casual blood sample of 200 mg/dL or higher in a person with classic symptoms is a diagnostic criterion for diabetes. This choice aligns with the typical clinical presentation of diabetes and is a key diagnostic indicator. Choices A, C, and D do not accurately reflect the established criteria for diagnosing diabetes, making them incorrect. Choice A pertains to a fasting plasma glucose level, Choice C involves a glucose challenge test, and Choice D refers to HbA1C levels, which are used for monitoring blood sugar control over time, not for diagnosing diabetes.

5. A patient following a vegetarian diet might be at risk for deficiency in which nutrient?

• A. Vitamin C
• B. Vitamin B12
• C. Vitamin A
• D. Vitamin D

Correct answer: B

Rationale: Vitamin B12 is primarily found in animal products, so vegetarians may need supplementation.
