Nutrition Final Exam

1. What is the study of how a person's genes interact with nutrients?

Correct answer: B

Rationale: Nutritional genomics, the correct answer, specifically focuses on how a person's genes interact with nutrients, affecting health and disease. Genetic counseling (choice A) refers to the process of helping people understand and adapt to the medical, psychological, and familial implications of genetic contributions to disease. Genetic metabolomics (choice C) combines genetic and metabolomic data to study metabolic pathways. Nutritional genetics (choice D) generally refers to the broader field of genetics as it relates to nutrition, while nutritional genomics, the most precise term, delves into the specific gene-nutrient interactions.

2. What is a primary intervention for a child with a suspected respiratory infection?

Correct answer: B

Rationale: Increasing fluid intake and rest is a primary intervention for a child with a suspected respiratory infection because it helps support the body’s recovery and maintains hydration levels. Antiviral medications (Choice A) are only used for specific viral infections and are not routinely recommended for suspected respiratory infections. Restricting physical activity (Choice C) may be necessary in certain cases to prevent overexertion, but it is not a primary intervention. Providing high-dose vitamin supplements (Choice D) may support the immune system in general but is not a primary intervention for a suspected respiratory infection.

3. What is a common treatment for a child with moderate to severe eczema?

Correct answer: A

Rationale: Topical corticosteroids are the correct answer for a child with moderate to severe eczema. These medications are commonly used to reduce inflammation and itching associated with eczema. Oral antibiotics (Choice B) are not typically used in eczema treatment unless there is a secondary bacterial infection. Frequent saline irrigation (Choice C) may aid in wound care but is not a primary treatment for eczema. A high-calcium diet (Choice D) is not a standard treatment for eczema and does not target the underlying inflammatory process that causes eczema symptoms.

4. What does a positive correlation between two variables indicate?

Correct answer: B

Rationale: A positive correlation between two variables indicates that they move in the same direction. This means that as one variable increases (or decreases), the other variable also increases (or decreases). Choice A is incorrect because correlation does not imply causation; it only shows a relationship between variables. Choice C is incorrect as it describes a negative correlation where variables move in opposite directions. Choice D is incorrect as a positive correlation implies a relationship between the variables.

5. What is an important aspect of care for a child with congenital adrenal hyperplasia?

Correct answer: A

Rationale: The correct answer is A: Monitoring electrolyte levels. In the management of congenital adrenal hyperplasia, it is crucial to monitor electrolyte levels to prevent imbalances and related complications. Restricting physical activity (choice B) is not a typical aspect of care for this condition. Administering high doses of vitamin A (choice C) is not a standard treatment for congenital adrenal hyperplasia and can be harmful in excess. Providing a high-protein diet (choice D) may be beneficial for some conditions but is not a specific requirement for managing congenital adrenal hyperplasia.
