What is the study of how a person's genes interact with nutrients?
- A. genetic counseling
- B. nutritional genomics
- C. genetic metabolomics
- D. nutritional genetics
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.

What is an important dietary consideration for a child with cystic fibrosis?
- A. High-calorie, high-fat diet
- B. Low-sugar diet
- C. Increased dietary fiber
- D. High-sodium diet
Correct Answer: A
Rationale: For a child with cystic fibrosis, an important dietary consideration is a high-calorie, high-fat diet. This type of diet helps address malabsorption issues commonly seen in individuals with cystic fibrosis and supports adequate growth and development. High-calorie, high-fat foods are recommended to help meet the increased energy needs of these individuals. Choices B, C, and D are not the most appropriate dietary considerations for a child with cystic fibrosis. A low-sugar diet may not provide enough calories for optimal growth, increased dietary fiber may exacerbate issues related to malabsorption, and a high-sodium diet is generally not recommended due to the risk of dehydration and electrolyte imbalances in individuals with cystic fibrosis.
What is a key intervention for a child with a new diagnosis of type 1 diabetes?
- A. Insulin administration
- B. Increased dietary fat intake
- C. Restricted fluid intake
- D. Routine physical examinations only
Correct Answer: A
Rationale: The correct answer is A: Insulin administration. When a child is diagnosed with type 1 diabetes, insulin administration is a crucial intervention. Insulin helps regulate blood glucose levels by enabling cells to take in glucose from the bloodstream. Without sufficient insulin, blood glucose levels can become dangerously high, leading to various complications. Increased dietary fat intake (choice B) is not a recommended intervention for type 1 diabetes management, as it can contribute to weight gain and other health issues. Restricted fluid intake (choice C) is also not appropriate, as adequate hydration is essential for overall health. Routine physical examinations (choice D) are important but are not the primary intervention needed to manage type 1 diabetes.
What is the smallest amount of a nutrient that, when consumed over a prolonged period, maintains a specific function?
- A. nutrient allowance
- B. nutrient requirement
- C. nutrient tolerable limit
- D. nutrient adequate intake
Correct Answer: B
Rationale: The correct answer is 'B: nutrient requirement.' The nutrient requirement refers to the smallest amount of a nutrient that, when consumed over a prolonged period, maintains a specific function in the body. This amount ensures the body's optimal functioning and health. Choice A, 'nutrient allowance,' is incorrect as it does not specifically refer to the minimum amount needed for bodily functions but rather suggests a broader term. Choice C, 'nutrient tolerable limit,' is incorrect as it pertains to the maximum amount of a nutrient that can be consumed without adverse effects. Choice D, 'nutrient adequate intake,' is incorrect as it refers to the recommended average daily intake level of a nutrient to meet the requirements of most healthy individuals.
What is a common side effect of corticosteroid therapy in children?
- A. Increased appetite
- B. Decreased blood glucose levels
- C. Inhibited growth
- D. Mood changes
Correct Answer: A
Rationale: The correct answer is A: Increased appetite. Corticosteroid therapy commonly causes increased appetite in children. This side effect can lead to weight gain and other metabolic changes. Option B is incorrect because corticosteroid therapy is more likely to result in increased blood glucose levels. Option C is incorrect because corticosteroid therapy can inhibit growth due to its impact on the endocrine system. Option D is incorrect because corticosteroid therapy can lead to mood changes such as irritability or even mood swings rather than improved mood.
What is the appropriate intervention for a child with an undescended testicle?
- A. Wait until puberty
- B. Perform an orchidopexy
- C. Administer hormone therapy
- D. Increase physical activity
Correct Answer: B
Rationale: The appropriate intervention for a child with an undescended testicle is to perform an orchidopexy. This surgical procedure is recommended if the testicle has not descended naturally within the first year of life. Waiting until puberty is not advised as early intervention is crucial for optimal outcomes. Administering hormone therapy is not the first-line treatment for an undescended testicle and is typically not recommended. Increasing physical activity does not address the underlying issue of an undescended testicle and is not a suitable intervention.
