Correct Answer: C

Rationale: Folic acid is the most critical nutrient for preventing neural tube defects during pregnancy. Neural tube defects are serious birth defects of the brain and spinal cord. Adequate intake of folic acid before and during early pregnancy can significantly reduce the risk of these defects. Iron, calcium, and vitamin D are important nutrients during pregnancy for other reasons, such as supporting the increased demands on the body for blood production, bone health, and calcium absorption, respectively.

Correct Answer: D

Rationale: Integrated Management of Childhood Illness (IMCI) is a strategy developed by WHO and UNICEF. The key components of IMCI include integrated case management of childhood illnesses, where healthcare providers are trained to assess, classify, and treat common childhood illnesses holistically. This approach aims to improve the quality of care for children under five years of age by focusing on overall health, nutrition, immunization, and family and community practices. Therefore, promoting hospital-based care, providing routine immunizations, and enhancing maternal nutrition, while important, are not the sole key components of the IMCI strategy.

Correct Answer: B

Rationale: Breastfeeding provides passive immunity to the infant by transferring antibodies from the mother to protect the infant from infections and illnesses. This is one of the key benefits of breastfeeding, as it helps boost the baby's immune system during the early stages of life.

Correct Answer: B

Rationale: Children aged 1-4 years are most vulnerable to protein-energy malnutrition (PEM) due to their rapid growth and development, increased nutritional requirements, and sometimes inadequate diets. This age group is particularly susceptible to malnutrition if they do not receive adequate protein and energy-rich foods to support their growth and development.

Correct Answer: C

Rationale: Vaccination is the most effective method for preventing the spread of infectious diseases as it helps in developing immunity against specific pathogens, reducing the likelihood of infection and transmission within a population. Antibiotics are used to treat infections, not prevent their spread. Quarantine limits the contact of infected individuals but does not provide long-term prevention. Nutritional supplementation can support overall health but is not a primary method for preventing infectious diseases.
