Which of the following is an example of a vector-borne disease?
- A. Measles
- B. Tuberculosis
- C. Malaria
- D. Hepatitis B
Correct Answer: C
Rationale: The correct answer is C: Malaria. Malaria is an example of a vector-borne disease because it is transmitted to humans through the bite of an infected mosquito. The mosquito acts as a vector, carrying and transmitting the infectious agent (Plasmodium parasite) from one host to another. Measles (A), Tuberculosis (B), and Hepatitis B (D) are not vector-borne diseases. Measles is transmitted through respiratory droplets, Tuberculosis through airborne particles, and Hepatitis B through contact with infected blood or body fluids.

Which of the following is an essential nutrient required for preventing neural tube defects?
- A. Iron
- B. Vitamin C
- C. Calcium
- D. Folic acid
Correct Answer: D
Rationale: The correct answer is D: Folic acid. Folic acid is essential for preventing neural tube defects because it plays a crucial role in DNA synthesis and cell division, particularly during early fetal development. Adequate folic acid intake before and during pregnancy can significantly reduce the risk of neural tube defects. Iron (A), Vitamin C (B), and Calcium (C) are important nutrients for overall health but do not have a direct role in preventing neural tube defects. Iron is vital for red blood cell production, Vitamin C is an antioxidant that supports the immune system, and Calcium is essential for bone health. However, for preventing neural tube defects specifically, folic acid is the essential nutrient.
What is the primary benefit of exclusive breastfeeding for the first 6 months of life?
- A. Prevents childhood obesity
- B. Ensures complete nutrition for the infant
- C. Increases the risk of allergies
- D. Delays cognitive development
Correct Answer: B
Rationale: Exclusive breastfeeding for the first 6 months provides complete nutrition for the infant, meeting all their dietary needs. Breast milk contains essential nutrients and antibodies that support healthy growth and development. It also helps to strengthen the baby's immune system and reduce the risk of infections. Ensuring complete nutrition through breastfeeding is crucial for optimal health outcomes in the early stages of life. Preventing childhood obesity, increasing the risk of allergies, and delaying cognitive development are not directly linked to exclusive breastfeeding and are therefore incorrect choices.
What is the purpose of the Expanded Program on Immunization (EPI)?
- A. To provide emergency medical services
- B. To ensure all children receive routine immunizations
- C. To offer specialized treatments for rare diseases
- D. To manage chronic health conditions
Correct Answer: B
Rationale: The correct answer is B because the purpose of the Expanded Program on Immunization (EPI) is to ensure all children receive routine immunizations to prevent various communicable diseases. EPI focuses on providing vaccines to children at specific ages to build immunity and protect them from serious illnesses. It does not provide emergency medical services (A), offer specialized treatments for rare diseases (C), or manage chronic health conditions (D). By prioritizing routine immunizations, EPI aims to reduce the burden of vaccine-preventable diseases and improve overall public health.
Which nutrient is most critical for preventing neural tube defects during pregnancy?
- A. Iron
- B. Calcium
- C. Folic acid
- D. Vitamin D
Correct Answer: C
Rationale: The correct answer is C: Folic acid. Folic acid is critical for preventing neural tube defects as it is essential for proper development of the neural tube in the fetus. It helps in the formation of the baby's brain and spinal cord. Iron (A) is important for preventing anemia, not neural tube defects. Calcium (B) is crucial for bone health but not directly related to neural tube development. Vitamin D (D) is important for calcium absorption, but not specifically for preventing neural tube defects. Overall, folic acid stands out as the most critical nutrient for this purpose.
Which of the following is an example of a waterborne disease?
- A. Hepatitis A
- B. Influenza
- C. Measles
- D. Tuberculosis
Correct Answer: A
Rationale: The correct answer is A: Hepatitis A. Waterborne diseases are caused by pathogens that are transmitted through contaminated water. Hepatitis A is a viral infection that spreads through the consumption of contaminated water or food. It affects the liver and is commonly associated with poor sanitation and hygiene. Influenza, Measles, and Tuberculosis are not waterborne diseases. Influenza and Measles are viral infections spread through respiratory droplets, while Tuberculosis is a bacterial infection primarily transmitted through the air. Hepatitis A is the only choice that aligns with the definition of a waterborne disease.
