1. What is one function of water in the human body?

• A. Water provides calories for energy.
• B. Water helps transport nutrients and waste products.
• C. Water acts as a solvent for many biological reactions.
• D. Water maintains body temperature.

Correct answer: B

Rationale: The correct answer is B: Water helps transport nutrients and waste products. Water plays a crucial role in the body by aiding in the transportation of essential nutrients to cells and removing waste products. While water is essential for various metabolic processes, it does not provide calories for energy (choice A). Although water can act as a solvent for biological reactions (choice C), its primary function is not as a solvent. Additionally, while water does help in regulating body temperature to some extent, its main role is not to maintain body temperature (choice D).

2. 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.

3. 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.

4. What is a crucial aspect of managing a child with cystic fibrosis?

• A. High-sugar diet
• B. Daily chest physiotherapy
• C. Frequent use of antacids
• D. Limiting fluid intake

Correct answer: B

Rationale: Daily chest physiotherapy is crucial in managing cystic fibrosis as it helps clear mucus from the lungs, improves respiratory function, and reduces the risk of lung infections. High-sugar diets are not recommended for individuals with cystic fibrosis as they can contribute to mucus production, exacerbating respiratory issues. Frequent use of antacids is not a primary treatment for cystic fibrosis, as it does not address the underlying lung issues. Limiting fluid intake is not typically advised for individuals with cystic fibrosis, as adequate hydration is essential for maintaining lung function and thinning mucus secretions.

5. What is an important aspect of managing a child with chronic kidney disease?

• A. Monitoring electrolyte levels
• B. Increasing protein intake
• C. Limiting fluid intake
• D. Encouraging a high-fat diet

Correct answer: A

Rationale: Monitoring electrolyte levels is crucial in managing chronic kidney disease in children because imbalances can lead to serious complications. Electrolyte levels must be carefully monitored to prevent issues such as electrolyte abnormalities, which can further impact kidney function and overall health. Choices B, C, and D are incorrect because increasing protein intake, limiting fluid intake, and encouraging a high-fat diet can exacerbate kidney disease in children by putting extra strain on their kidneys or causing other health problems.
