1. What is an important consideration when administering medications to a child with hepatic dysfunction?

• A. Increased dosing intervals
• B. Adjustments in dosage due to altered metabolism
• C. Avoid all medications
• D. Use only topical medications

Correct answer: B

Rationale: When administering medications to a child with hepatic dysfunction, it is crucial to make adjustments in dosage due to altered metabolism. Hepatic dysfunction can affect the way medications are metabolized in the body, potentially leading to drug toxicity or reduced effectiveness. This is why adjusting the dosage is essential to ensure the medication is both safe and efficient. Choices A, C, and D are incorrect because increasing dosing intervals, avoiding all medications, or using only topical medications do not address the specific issue of altered drug metabolism in hepatic dysfunction.

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. What is the primary goal in managing a child with cystic fibrosis?

• A. Increase dietary fat intake
• B. Prevent lung infections
• C. Increase physical activity
• D. Ensure high protein intake

Correct answer: B

Rationale: The primary goal in managing a child with cystic fibrosis is to prevent lung infections. Cystic fibrosis primarily affects the respiratory system, leading to thick mucus buildup in the lungs, which increases the risk of infections. Preventing lung infections through proper respiratory care, medications, airway clearance techniques, and vaccinations is crucial in managing cystic fibrosis. While dietary interventions like increasing dietary fat intake, ensuring high protein intake, and promoting physical activity are also important aspects of cystic fibrosis management, preventing lung infections takes precedence as it directly addresses a major complication of the condition.

4. What is a key dietary consideration for a child with phenylketonuria (PKU)?

• A. High-fiber diet
• B. Low-phenylalanine diet
• C. Increased dairy intake
• D. High-sodium diet

Correct answer: B

Rationale: A low-phenylalanine diet is crucial for managing PKU to prevent neurological damage and maintain normal development. Phenylalanine is an amino acid found in protein-containing foods, and individuals with PKU have difficulty metabolizing it. Consuming foods low in phenylalanine helps prevent the buildup of toxic byproducts in the body. Choices A, C, and D are incorrect. A high-fiber diet, increased dairy intake, and high-sodium diet are not specific dietary considerations for PKU management. In fact, dairy products are a source of protein and phenylalanine, which should be limited in PKU.

5. Gram for gram, which class of nutrient provides the most energy?

• A. fats
• B. alcohols
• C. proteins
• D. carbohydrates

Correct answer: A

Rationale: The correct answer is fats. Fats provide 9 kilocalories per gram, which is more energy-dense compared to proteins and carbohydrates. While proteins and carbohydrates provide 4 kilocalories per gram, fats provide more than twice the energy, making them the most energy-providing nutrient. Alcohols are not considered essential nutrients and do not provide energy for the body, unlike fats, proteins, and carbohydrates. Therefore, fats are the correct answer for the most energy-providing nutrient.
