1. Which nutrient is classified as a micronutrient?

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

Correct answer: A

Rationale: The correct answer is minerals. Micronutrients are required by the body in smaller amounts compared to macronutrients like proteins and carbohydrates. Proteins are macronutrients necessary for growth and repair, not classified as micronutrients. Alcohols and carbohydrates are not classified as micronutrients either.

2. Which nutrient is an organic compound?

• A. salt
• B. water
• C. calcium
• D. vitamin C

Correct answer: D

Rationale: Vitamin C is the correct answer because it is an organic compound containing carbon, which is a defining characteristic of organic compounds. Salt (choice A), water (choice B), and calcium (choice C) are inorganic compounds that do not contain carbon. Inorganic compounds are typically lacking carbon-hydrogen bonds, unlike organic compounds. Therefore, choices A, B, and C are incorrect in the context of being organic compounds.

3. What is the most common symptom of appendicitis in children?

• A. Vomiting and diarrhea
• B. Fever and abdominal pain
• C. Rash and joint pain
• D. Difficulty breathing

Correct answer: B

Rationale: The correct answer is B: Fever and abdominal pain. In children, appendicitis commonly presents with fever and abdominal pain. The pain typically begins around the umbilicus and then moves to the lower right quadrant. Choices A, C, and D are incorrect because vomiting and diarrhea, rash and joint pain, and difficulty breathing are not typical symptoms of appendicitis in children.

4. 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.

5. What is a common treatment for a child with iron-deficiency anemia?

• A. Iron supplements
• B. High-protein diet
• C. Vitamin B12 injections
• D. Sodium chloride solution

Correct answer: A

Rationale: Iron supplements are the correct choice for treating iron-deficiency anemia in children. Iron supplements help replenish the low iron levels in the body, addressing the underlying cause of the anemia. High-protein diets may be beneficial for overall health but are not the primary treatment for iron-deficiency anemia. Vitamin B12 injections are used to treat B12 deficiency anemia, a different type of anemia. Sodium chloride solution is not a treatment for anemia and is typically used for hydration purposes.
