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. 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.

3. What should be included in the medical management of a sickle cell crisis?

• A. Information for parents on home care
• B. Adequate hydration and pain management
• C. Pain management and iron supplements
• D. Adequate oxygenation and factor VIII

Correct answer: B

Rationale: The correct answer is B: Adequate hydration and pain management. During a sickle cell crisis, it is essential to provide hydration to prevent vaso-occlusive events and manage pain effectively with analgesics. Adequate hydration helps maintain blood flow and prevent further sickling of red blood cells. Pain management is crucial to alleviate the severe pain associated with sickle cell crises. Options A, C, and D are incorrect. Providing information for parents on home care (Option A) may be important for ongoing management but is not specific to an acute crisis. Iron supplements (Option C) are not typically indicated during a sickle cell crisis. Adequate oxygenation and factor VIII (Option D) are not primary interventions for managing a sickle cell crisis; instead, oxygen therapy may be considered in severe cases, and factor VIII is not a standard treatment for sickle cell disease.

4. How many vitamins are known to be required in the diet of human beings?

• A. 5
• B. 8
• C. 10
• D. 13

Correct answer: D

Rationale: The correct answer is D: 13. There are 13 essential vitamins required in the diet of human beings, including vitamins A, C, D, E, K, and the B vitamins. Choice A (5), Choice B (8), and Choice C (10) are incorrect because they do not represent the total number of essential vitamins needed by human beings.

5. What is a common sign of hypothyroidism in children?

• A. Weight loss
• B. Increased heart rate
• C. Dry skin and constipation
• D. Elevated blood pressure

Correct answer: C

Rationale: Dry skin and constipation are typical signs of hypothyroidism in children. Hypothyroidism results from an underactive thyroid gland, leading to symptoms such as dry skin and constipation. Weight loss (Choice A) is more commonly associated with hyperthyroidism, where the thyroid gland is overactive. Increased heart rate (Choice B) and elevated blood pressure (Choice D) are also more characteristic of hyperthyroidism rather than hypothyroidism. Therefore, the correct answer is dry skin and constipation (Choice C) when identifying signs of hypothyroidism in children.
