Correct Answer: C

Rationale: Breast milk is considered the best and most complete form of nutrition for infants below 6 months of age. It contains the ideal balance of nutrients, antibodies, and other components essential for the baby's growth, development, and immune system. Breast milk is easily digestible and helps protect infants from infections and illnesses. It is recommended by healthcare professionals as the optimal choice for feeding infants during the first 6 months of life.

Correct Answer: C

Rationale: The first dose of the MMR vaccine is typically administered to a child at 12 months of age to provide protection against measles, mumps, and rubella. Administering the vaccine at this age ensures that the child's immune system is developed enough to generate a protective response to the vaccine.

Correct Answer: B

Rationale: The correct answer is encouraging skin-to-skin contact after birth. The Baby-Friendly Hospital Initiative (BFHI) aims to promote breastfeeding and bonding by encouraging practices such as immediate skin-to-skin contact between mother and baby, rooming-in, and supporting exclusive breastfeeding. These practices have been shown to have numerous benefits for both the mother and the baby in terms of bonding, breastfeeding success, and overall health outcomes.

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: Administering antiretroviral therapy to HIV-positive mothers is a crucial practice to reduce the risk of mother-to-child transmission of HIV. Antiretroviral therapy helps lower the viral load in the mother's body, decreasing the chance of passing the virus to the child during pregnancy, childbirth, or breastfeeding. Exclusive breastfeeding, using unsterilized medical equipment, and avoiding prenatal care do not directly contribute to reducing HIV transmission from mother to child.
