Correct Answer: B

Rationale: The World Health Organization recommends exclusive breastfeeding for the first 6 months of a child's life. During this time, breast milk provides all the necessary nutrients for the baby's growth and development, offering protection against infections and supporting optimal health outcomes. After 6 months, complementary foods can be introduced while continuing breastfeeding up to 2 years of age or beyond.

Correct Answer: D

Rationale: A comprehensive antenatal care program should encompass various components to ensure the well-being of the pregnant individual and the fetus. Weight monitoring helps track healthy weight gain during pregnancy, blood pressure measurement is crucial for detecting and managing conditions like preeclampsia, and nutritional counseling supports proper nutrition and healthy development. Including all these components in antenatal care ensures a holistic approach to monitoring and promoting the health of both the mother and the baby.

Correct Answer: B

Rationale: The primary purpose of the Field Health Services and Information System (FHSIS) is to record and report public health services. It is specifically designed to improve health service delivery and planning by systematically collecting, managing, and analyzing health-related data. Monitoring hospital services, evaluating private health services, and managing health insurance claims are not the primary functions of the FHSIS, which is focused on public health services.

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.

Correct Answer: C

Rationale: Antiretroviral therapy is a crucial strategy in preventing mother-to-child transmission of HIV. By providing antiretroviral medications to the mother during pregnancy, labor, and breastfeeding, the risk of transmitting the virus to the child is significantly reduced. This treatment approach has been shown to be highly effective in reducing the likelihood of HIV transmission from mother to child.
