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: D

Rationale: The Maternal and Child Health (MCH) program aims to reduce infant mortality, improve maternal health, and provide family planning services. It focuses on both preventive and curative care to promote the health and well-being of mothers and children. While curative care is a component of the program, it is not the sole focus as prevention and early intervention are equally important in achieving positive health outcomes.

Correct Answer: B

Rationale: The Global Immunization Vision and Strategy (GIVS) aims to improve access to high-quality immunization services globally. This objective focuses on enhancing the availability and quality of immunization services to ensure that more individuals have access to vaccines to prevent diseases.

Therefore, it is recommended that mothers with HIV do not breastfeed to prevent the transmission of the virus to their infants.

Correct Answer: A

Rationale: Frequent handwashing is a crucial practice for preventing the spread of healthcare-associated infections. Washing hands frequently helps remove pathogens and reduces the risk of transmitting infections between patients, healthcare providers, and other individuals in healthcare settings.
