Which of the following is a key strategy in the prevention of mother-to-child transmission of HIV?
- A. Exclusive breastfeeding
- B. Routine immunization
- C. Antiretroviral therapy
- D. Nutritional supplementation
Correct Answer: C
Rationale: The correct answer is C: Antiretroviral therapy. This is a key strategy because it involves giving HIV medications to the mother during pregnancy, labor, and delivery, as well as to the newborn, significantly reducing the risk of transmission. Antiretroviral therapy helps lower the viral load in the mother's body, making it less likely for the virus to be passed on to the child. Exclusive breastfeeding (choice A) can increase the risk of transmission, routine immunization (choice B) does not directly prevent mother-to-child transmission of HIV, and nutritional supplementation (choice D) is not a primary strategy for preventing transmission.

Which of the following practices can help reduce the transmission of HIV from mother to child?
- A. Exclusive breastfeeding
- B. Administering antiretroviral therapy
- C. Using unsterilized medical equipment
- D. Avoiding prenatal care
Correct Answer: B
Rationale: The correct answer is B: Administering antiretroviral therapy. Antiretroviral therapy helps reduce the viral load in the mother, decreasing the risk of transmitting HIV to the child during pregnancy, childbirth, and breastfeeding. It is a proven method recommended by the World Health Organization.
A: Exclusive breastfeeding can increase the risk of HIV transmission to the child if the mother is HIV positive.
C: Using unsterilized medical equipment can increase the risk of HIV transmission.
D: Avoiding prenatal care can lead to missed opportunities for prevention and treatment interventions.
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.
What is the recommended duration of exclusive breastfeeding?
- A. 3 months
- B. 6 months
- C. 9 months
- D. 12 months
Correct Answer: B
Rationale: The recommended duration of exclusive breastfeeding is 6 months. This is because breast milk provides all the necessary nutrients for an infant's growth and development in the first 6 months of life. Introducing solid foods too early can increase the risk of infections and allergies. Choice A (3 months) is not ideal as it may not provide sufficient nutrients for the baby's growth. Choices C (9 months) and D (12 months) exceed the recommended duration and may not be necessary for exclusive breastfeeding, as other foods can be introduced after 6 months.
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.
When is the recommended time for introducing solid foods into an infant's diet?
- A. 3 months
- B. 6 months
- C. 9 months
- D. 12 months
Correct Answer: B
Rationale: The correct answer is B: 6 months. At this age, infants' digestive systems are more developed and ready for solid foods. Introducing solids too early (A) can lead to allergies and digestion issues. Waiting until 9 months (C) or 12 months (D) can delay important nutrients and increase the risk of iron deficiency. In summary, introducing solids at 6 months strikes the right balance between developmental readiness and nutritional needs for infants.
