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. What best describes a task of the registered dietitian?

A. administering total parenteral nutrition
B. administering formula through feeding tubes
C. prescribing diet orders
D. conducting nutrition assessments

Correct answer: D

Rationale: The correct answer is D, conducting nutrition assessments. Registered dietitians are responsible for assessing an individual's nutritional status, dietary intake, and health needs. This assessment forms the basis for developing personalized nutrition care plans. Choices A and B involve the administration of specialized nutrition support, which is typically done by healthcare providers with specific training in those areas. Choice C, prescribing diet orders, may fall outside the scope of practice for a dietitian as they focus more on assessment, education, and counseling related to nutrition rather than prescribing medical treatments.

3. Approximately 75% of reputable producers of bottled water use groundwater as their water source. Plain tap water is the most natural source of fluids.

A. Both statements are true.
B. Both statements are false.
C. The first statement is true; the second is false.
D. The first statement is false; the second is true.

Correct answer: A

Rationale: Both statements are true. Approximately 75% of reputable producers of bottled water use groundwater as their water source, which is the same source as the public water supply. Plain tap water, coming from underground sources or reservoirs, is indeed a natural source of fluids. The first statement is supported by the fact that groundwater is a common source for bottled water due to its purity and taste. The second statement is true as tap water is sourced from natural reservoirs or underground aquifers in most cases, making it a natural fluid source for consumption. Other choices are incorrect because both statements are factually accurate based on common practices in the production and sourcing of bottled water and tap water.

4. What characterizes Obsessive Compulsive Disorder?

A. Uncontrollable impulse to perform an act or ritual repeatedly
B. Persistent thoughts and behavior
C. Recurring unwanted and disturbing thoughts
D. Pathological persistence of unwilled thoughts

Correct answer: A

Rationale: Obsessive Compulsive Disorder (OCD) is characterized by the uncontrollable impulse to perform an act or ritual repeatedly (Choice A). This is driven by recurring unwanted and disturbing thoughts (Choice C), but the distinguishing factor is the compulsive behavior, making choice A the most accurate. While choice B can be seen as true, it lacks the specific detail of the compulsive behavior that makes A a better answer. Choice D is not incorrect, but it uses terminology that is less precise and less commonly used to describe OCD, making it a less accurate choice than A. The provided rationale is not relevant to the question.

5. What are the best food sources of magnesium?

A. oils, bananas, and pork
B. pizza, potatoes, and tomatoes
C. milk, rice, and apples
D. legumes, whole grains, and chocolate

Correct answer: D

Rationale: The correct answer is D: legumes, whole grains, and chocolate. These foods are rich sources of magnesium, an essential mineral that plays a role in over 300 biochemical reactions in the body. Choices A, B, and C do not contain as high levels of magnesium compared to legumes, whole grains, and chocolate.
