1. A weight reduction regimen calls for a daily intake of 1400 kilocalories, which includes 30 grams of fat. What percentage of the total energy is contributed by fat?

• A. 8.50%
• B. 15.00%
• C. 19.00%
• D. 25.50%

Correct answer: C

Rationale: To calculate the percentage of total energy contributed by fat, first determine the energy from fat by multiplying the fat amount (30g) by the energy density of fat (9 kcal/g), which equals 270 kcal. Then, divide the energy from fat (270 kcal) by the total energy intake (1400 kcal) and multiply by 100 to find the percentage: (270 kcal / 1400 kcal) * 100 = 19.29% ≈ 19.00%. Therefore, fat contributes approximately 19% of the total energy in the diet. Choice A (8.50%) is too low, while choices B (15.00%) and D (25.50%) are incorrect calculations based on the given information.

2. 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.

3. What is the primary role of dietary guidelines?

• A. To ensure that all food groups are consumed in appropriate proportions.
• B. To prevent chronic diseases and promote overall well-being.
• C. To help individuals meet their nutritional needs while reducing the risk of chronic disease.
• D. To offer specific recommendations for the intake of nutrients that support health.

Correct answer: C

Rationale: The correct answer is C: 'To help individuals meet their nutritional needs while reducing the risk of chronic disease.' Dietary guidelines are designed to provide guidance on the types and amounts of food that support good health and reduce the risk of chronic diseases. Choice A has been corrected to mention 'appropriate proportions' instead of 'equal amounts,' as dietary guidelines emphasize balance and variety. Choice B is partially correct, but the primary focus of dietary guidelines is on meeting nutritional needs. Choice D is incorrect because while dietary guidelines may include nutrient recommendations, their primary focus is on overall dietary patterns rather than specific nutrient intake.

4. What is a key sign of meningitis in an infant?

• A. Increased appetite
• B. Bulging fontanel
• C. Decreased respiratory rate
• D. Elevated blood pressure

Correct answer: B

Rationale: A bulging fontanel is a key sign of meningitis in infants, indicating increased intracranial pressure due to inflammation of the meninges. This can lead to the fontanel bulging. Choices A, C, and D are incorrect. Increased appetite is not typically associated with meningitis in infants; instead, they may have poor feeding. A decreased respiratory rate is not a common sign of meningitis in infants. Elevated blood pressure is also not a typical finding in infants with meningitis.

5. What is a common complication of untreated asthma in children?

• A. Delayed puberty
• B. Growth retardation
• C. Chronic sinusitis
• D. Frequent headaches

Correct answer: C

Rationale: The correct answer is C: Chronic sinusitis. Untreated asthma can lead to chronic sinusitis in children due to prolonged inflammation and infection of the respiratory tract. Choices A, B, and D are incorrect. Delayed puberty and growth retardation are not common complications of untreated asthma in children. Frequent headaches may be associated with asthma exacerbations but are not typical long-term complications.
