What is one characteristic that differentiates vitamins from minerals?
- A. Vitamins are organic compounds.
- B. Vitamins provide energy.
- C. Vitamins are considered micronutrients.
- D. Vitamins are essential in small amounts.
Correct Answer: A
Rationale: The correct answer is A. Vitamins are organic compounds, containing carbon, which is a key characteristic that differentiates them from minerals. Choice B is incorrect because vitamins do not provide energy; they are not a source of calories. Choice C is incorrect as both vitamins and minerals are considered micronutrients due to being essential in small amounts. Choice D is incorrect because while it is true that vitamins are needed in small amounts, this is not the characteristic that sets them apart from minerals.

What is a common clinical manifestation of Kawasaki disease?
- A. Severe headaches
- B. High fever lasting more than 5 days
- C. Chronic cough
- D. Severe abdominal pain
Correct Answer: B
Rationale: A high fever lasting more than 5 days is a common clinical manifestation of Kawasaki disease. This fever is often accompanied by other symptoms such as rash and conjunctivitis. Severe headaches (Choice A), chronic cough (Choice C), and severe abdominal pain (Choice D) are not typically associated with Kawasaki disease, making them incorrect choices.
What is a common sign of an allergic reaction in children?
- A. Persistent cough
- B. Skin rash or hives
- C. Increased appetite
- D. Low-grade fever
Correct Answer: B
Rationale: Skin rash or hives are common signs of an allergic reaction in children, often following exposure to allergens. While a persistent cough can occur in some cases, it is not typically a primary sign of an allergic reaction. Increased appetite is unrelated to allergic reactions. A low-grade fever is not a common sign of an allergic reaction but can be present in other conditions like infections.
What type of vaccine should a child with a history of severe allergic reactions receive?
- A. Live attenuated vaccines
- B. Inactivated vaccines
- C. Subunit vaccines
- D. Recombinant vaccines
Correct Answer: B
Rationale: Children with a history of severe allergic reactions should receive inactivated vaccines because they do not contain live pathogens. Live attenuated vaccines (choice A) contain weakened live pathogens and can potentially trigger an allergic reaction in sensitive individuals. Subunit vaccines (choice C) and recombinant vaccines (choice D) may contain components that could still trigger an allergic response in individuals with a history of severe allergies. Inactivated vaccines are the safest choice for individuals with a history of severe allergic reactions as they do not pose a risk of causing an allergic reaction due to the absence of live pathogens.

What is a common sign of iron-deficiency anemia in children?
- A. Yellowing of the skin
- B. Pallor and fatigue
- C. Rapid weight gain
- D. Increased appetite
Correct Answer: B
Rationale: Pallor and fatigue are common signs of iron-deficiency anemia in children. Iron-deficiency anemia is characterized by a decreased production of red blood cells, leading to a paler appearance (pallor) and increased fatigue due to reduced oxygen-carrying capacity. Yellowing of the skin (choice A) is more commonly associated with liver or bile duct issues. Rapid weight gain (choice C) and increased appetite (choice D) are not typical signs of iron-deficiency anemia.
