1. What is a key intervention for a child with a new diagnosis of asthma?

• A. Provide a peak flow meter
• B. Limit all physical activity
• C. Increase dairy consumption
• D. Recommend frequent use of nasal decongestants

Correct answer: A

Rationale: The correct answer is A: Provide a peak flow meter. Providing a peak flow meter is crucial for a child with a new diagnosis of asthma as it helps monitor asthma control and manage symptoms by tracking changes in airflow. This device assists in assessing how well the lungs are functioning and guides treatment decisions. Limiting all physical activity (choice B) is not recommended as regular exercise can actually help improve lung function in asthmatic children. Increasing dairy consumption (choice C) is not a key intervention for asthma, and recommending frequent use of nasal decongestants (choice D) is not suitable for asthma management in children.

2. What is critical for preventing complications in an infant with hypothyroidism?

• A. Excessive growth
• B. Cognitive impairment
• C. Damage to the nervous system
• D. Damage to the urinary system

Correct answer: B

Rationale: The correct answer is B: Cognitive impairment. In infants with hypothyroidism, prompt administration of oral thyroid hormone replacement is crucial to prevent cognitive impairment and other serious complications. Excessive growth (choice A) is not a typical complication of hypothyroidism in infants. While hypothyroidism can affect the nervous system (choice C), cognitive impairment is more specific to untreated cases. Damage to the urinary system (choice D) is not a common complication of hypothyroidism in infants.

3. What is one characteristic that differentiates vitamins from minerals?

• A. Vitamins are organic compounds.
• B. Vitamins provide energy.
• C. Vitamins are considered micronutrients.
• D. Vitamins are essential in small amounts.

Correct answer: A

Rationale: The correct answer is A. Vitamins are organic compounds, containing carbon, which is a key characteristic that differentiates them from minerals. Choice B is incorrect because vitamins do not provide energy; they are not a source of calories. Choice C is incorrect as both vitamins and minerals are considered micronutrients due to being essential in small amounts. Choice D is incorrect because while it is true that vitamins are needed in small amounts, this is not the characteristic that sets them apart from minerals.

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. What is the main purpose of Recommended Dietary Allowances (RDAs)?

• A. To provide guidelines for nutrient intakes that meet the needs of most healthy people.
• B. To specify the minimum amount of nutrients required for survival.
• C. To establish maximum safe levels of nutrient intakes.
• D. To recommend specific nutrient intake levels to prevent chronic diseases.

Correct answer: A

Rationale: The main purpose of Recommended Dietary Allowances (RDAs) is to provide guidelines for nutrient intakes that meet the needs of most healthy people. Choice B is incorrect because RDAs aim beyond just survival requirements. Choice C is incorrect because establishing maximum safe levels is the role of Tolerable Upper Intake Levels (ULs). Choice D is incorrect because preventing chronic diseases is more associated with Dietary Reference Intakes (DRIs) like Adequate Intakes (AIs) and Tolerable Upper Intake Levels (ULs). Therefore, the correct answer is A.
