1. What is a common symptom of a vitamin D deficiency in children?

• A. Frequent infections
• B. Bone pain and tenderness
• C. Excessive thirst
• D. Unexplained bruising

Correct answer: B

Rationale: Bone pain and tenderness are indeed common symptoms of vitamin D deficiency in children. Vitamin D plays a crucial role in bone health and growth. The deficiency can lead to weakened bones, causing pain and tenderness. Choices A, C, and D are incorrect. Frequent infections are not a typical symptom of vitamin D deficiency in children; excessive thirst is more commonly associated with conditions like diabetes, and unexplained bruising is not directly linked to vitamin D deficiency.

2. What is the primary source of energy for the brain and nervous system?

• A. Protein
• B. Fat
• C. Carbohydrate
• D. Glucose

Correct answer: D

Rationale: Glucose is the correct answer as it is the primary source of energy for the brain and nervous system. The brain relies heavily on glucose to function optimally. While protein and fat play essential roles in the body, they are not the primary sources of energy for the brain and nervous system. Carbohydrates, on the other hand, are broken down into glucose, which is then used as fuel by the brain and nervous system.

3. Which of the following is considered a micronutrient?

• A. Protein
• B. Carbohydrate
• C. Vitamin C
• D. Fat

Correct answer: C

Rationale: Corrected Question: Vitamin C is considered a micronutrient because it is required in small amounts for proper body functioning and is essential for health. Proteins, carbohydrates, and fats are macronutrients, needed in larger quantities for energy and other body functions. Vitamin C, being a micronutrient, plays a crucial role in various bodily functions even though it is needed in smaller quantities compared to macronutrients. Therefore, the correct answer is C. Choice A (Protein), Choice B (Carbohydrate), and Choice D (Fat) are incorrect as they are macronutrients required in larger amounts for energy and other body functions.

4. 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.

5. What is an important dietary consideration for a child with renal failure?

• A. Low-protein, low-sodium diet
• B. High-protein, high-sodium diet
• C. Increased calcium intake
• D. High-fiber diet

Correct answer: A

Rationale: A low-protein, low-sodium diet is crucial for a child with renal failure because it helps reduce the workload on the kidneys and minimize complications. High-protein and high-sodium diets can place excessive strain on the kidneys and worsen the condition. Increased calcium intake is not typically a primary consideration for renal failure in children. While a high-fiber diet can be beneficial for overall health, it is not a specific priority for managing renal failure in children.
