1. Which nutrient is an example of a macronutrient?

• A. proteins
• B. minerals
• C. water-soluble vitamins
• D. fat-soluble vitamins

Correct answer: A

Rationale: Proteins are indeed macronutrients as they are required by the body in larger quantities for various functions such as growth, repair, and energy production. Choice B, minerals, are micronutrients needed in smaller amounts for various physiological processes. Choices C and D, water-soluble vitamins and fat-soluble vitamins, respectively, are also micronutrients that play essential roles in the body but are not classified as macronutrients.

2. What is the primary reason influencing most people's food choices?

• A. cost
• B. taste
• C. convenience
• D. nutritional value

Correct answer: B

Rationale: The primary reason most people choose the foods they eat is taste. While cost, convenience, and nutritional value also play a role in food choices, taste often takes precedence as people are more likely to select foods that they find appealing in flavor. Therefore, options A, C, and D are incorrect as taste is the chief factor influencing food choices.

3. Which nutrient is an organic compound?

• A. salt
• B. water
• C. calcium
• D. vitamin C

Correct answer: D

Rationale: Vitamin C is the correct answer because it is an organic compound containing carbon, which is a defining characteristic of organic compounds. Salt (choice A), water (choice B), and calcium (choice C) are inorganic compounds that do not contain carbon. Inorganic compounds are typically lacking carbon-hydrogen bonds, unlike organic compounds. Therefore, choices A, B, and C are incorrect in the context of being organic compounds.

4. What is the term for the study of how diet affects gene expression?

• A. Epigenetics
• B. Nutrigenomics
• C. Genomics
• D. Genetics

Correct answer: B

Rationale: Nutrigenomics is the study of how diet affects gene expression, influencing health outcomes and disease risk. Epigenetics (choice A) involves changes in gene expression or cellular phenotype caused by mechanisms other than changes in the underlying DNA sequence. Genomics (choice C) is the study of an organism's entire genome. Genetics (choice D) is the study of heredity and the variation of inherited characteristics.

5. How should the healthcare provider respond to a parent concerned about a child's short stature?

• A. Suggest the parent consult a nutritionist
• B. Recommend frequent growth hormone injections
• C. Advise monitoring for a few years before intervention
• D. Refer for a genetic evaluation

Correct answer: C

Rationale: When a parent expresses concern about a child's short stature, the initial approach should involve advising monitoring for a few years before considering any interventions. This allows for observation of the child's growth pattern and any potential underlying issues. Suggesting a nutritionist (Choice A) may not be necessary if there are no signs of nutritional deficiencies. Recommending growth hormone injections (Choice B) is premature without proper evaluation and diagnosis. Referring for a genetic evaluation (Choice D) can be considered later if monitoring shows atypical growth patterns or other concerning factors.
