1. Each of the following accurately describes aspects of the dietary reference intakes (DRIs) published by the Food and Nutrition Board of the Institute of Medicine (IOM) except one. Which one is the exception?

A. The DRIs replace the older recommended daily allowances
B. Current DRIs attempt to estimate required nutrients to improve long-term health
C. DRIs specifically address individuals whose requirements are affected by a disease state
D. The DRIs attempt to establish maximum safe levels of tolerance for nutrients

Correct answer: C

Rationale: The correct answer is C. DRIs are intended for the general population and do not specifically address disease states, which are managed with different clinical guidelines. Choice A is correct as DRIs have replaced the older recommended daily allowances. Choice B is correct as current DRIs aim to estimate the required nutrients for long-term health. Choice D is correct as DRIs also attempt to establish maximum safe levels of tolerance for nutrients.

2. Sam is trying to lose weight by skipping lunch. By the middle of the afternoon, Sam is very uncomfortable and feels that they "have" to eat. Sam is experiencing:

A. appetite
B. satiety
C. satiation
D. hunger

Correct answer: D

Rationale: Hunger is the physiological need to eat, which Sam is experiencing due to skipping a meal and the body signaling the need for nutrients.

3. Medications that reduce stomach acidity can impair the absorption of _____.

A. calcium
B. iron
C. vitamin D
D. vitamin C

Correct answer: B

Rationale: Reduced stomach acidity impairs the absorption of iron, as an acidic environment is necessary for optimal iron absorption in the stomach. Choices A, C, and D are incorrect as medications that reduce stomach acidity typically do not significantly affect the absorption of calcium, vitamin D, or vitamin C.

4. What physiologic role does calcium play in the body?

A. Blood clotting, transmission of nerve impulses, muscle contraction and relaxation
B. Calcium homeostasis, structural integrity of heart muscle
C. No known metabolic function, caries-preventing properties
D. ATP energy release; metabolism of fats, carbohydrates, proteins; regulates acid-base balance.

Correct answer: A

Rationale: The correct answer is A: 'Blood clotting, transmission of nerve impulses, muscle contraction and relaxation.' Calcium plays a crucial role in various physiological functions such as blood clotting, transmission of nerve impulses, muscle contraction and relaxation, membrane permeability, and activation of certain enzymes. Choice B is incorrect because while calcium is involved in calcium homeostasis, it is not the only role it plays in the body. Choice C is incorrect as calcium indeed has several known metabolic functions, and it is not solely for preventing caries. Choice D is also incorrect as the functions mentioned are primarily carried out by other nutrients and not specifically by calcium.

5. The equal sharing of resources is known as _____.

A. autonomy
B. ethics
C. disclosure
D. distributive justice

Correct answer: D

Rationale: The correct answer is D, distributive justice. Distributive justice involves the fair and equitable distribution of resources among all individuals in society. Option A, autonomy, refers to the right of individuals to make their own decisions. Option B, ethics, pertains to moral principles. Option C, disclosure, refers to the act of making information known.
