Nutrition Final Exam
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 aspect of care for a child with congenital heart disease?
- A. Restricting physical activity
- B. Increasing fluid intake
- C. Administering high doses of vitamins
- D. Monitoring growth and development
Correct answer: D
Rationale: Monitoring growth and development is crucial for children with congenital heart disease to ensure they are meeting developmental milestones and managing the disease effectively. This helps healthcare providers assess the child's overall health, detect any potential issues early, and adjust treatment plans accordingly. Restricting physical activity may not be necessary for all children with congenital heart disease and should be determined by their healthcare team based on individual needs. Increasing fluid intake and administering high doses of vitamins may not be directly related to managing congenital heart disease and should be guided by specific recommendations from healthcare providers.
3. How should hydration status in a child with fever and vomiting be assessed?
- A. Monitor skin turgor and mucous membranes
- B. Measure blood glucose levels
- C. Check for signs of jaundice
- D. Assess respiratory rate
Correct answer: A
Rationale: To assess hydration status in a child with fever and vomiting, monitoring skin turgor and mucous membranes is essential. Skin turgor refers to the skin's ability to change shape and return to normal; poor skin turgor can indicate dehydration. Mucous membranes, such as the mouth and eyes, can also provide valuable information about hydration levels. Measuring blood glucose levels (Choice B) is not directly related to assessing hydration status. Checking for signs of jaundice (Choice C) is important for liver-related issues, not hydration assessment. Assessing respiratory rate (Choice D) is crucial for evaluating respiratory function, not hydration status.
4. What intervention is recommended for a child with severe dehydration?
- A. Oral rehydration therapy
- B. Intravenous fluid replacement
- C. High-protein diet
- D. Increased physical activity
Correct answer: B
Rationale: Intravenous fluid replacement is the recommended intervention for a child with severe dehydration because it allows for rapid restoration of fluid and electrolyte balance. In severe cases, oral rehydration therapy (Choice A) may not be tolerated due to the child's condition. A high-protein diet (Choice C) is not the primary intervention and does not address the immediate fluid and electrolyte imbalance. Increased physical activity (Choice D) is contraindicated in severe dehydration as it can exacerbate fluid loss, making intravenous fluid replacement the most suitable choice for prompt correction of the severe dehydration.
5. Which nutrient source yields more than 4 kcalories per gram?
- A. plant fats
- B. plant proteins
- C. animal proteins
- D. plant carbohydrates
Correct answer: A
Rationale: The correct answer is plant fats (Choice A). Fats, including plant fats, provide 9 kcalories per gram, which is more than 4 kcalories. Plant proteins (Choice B) and animal proteins (Choice C) provide 4 kcalories per gram. Plant carbohydrates (Choice D) also provide 4 kcalories per gram. Therefore, Choices B, C, and D are incorrect because they do not yield more than 4 kcalories per gram.
