Correct Answer: A

Rationale: Hepatitis A is a waterborne disease caused by a virus that can be transmitted through contaminated water or food. Ingestion of even microscopic amounts of fecal matter from an infected person can lead to infection. It is important to practice good hygiene and ensure water sources are clean to prevent the spread of Hepatitis A.

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.

Correct Answer: C

Rationale: Secondary prevention focuses on early detection and intervention to prevent the progression of diseases. Screening for hypertension falls under secondary prevention as it aims to identify the condition early, allowing for timely management and prevention of complications.

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: 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.
