## **Core Concept**
The prevention of mother-to-child transmission (PMTCT) of HIV involves a multifaceted approach, including antiretroviral therapy (ART) for the pregnant woman, elective cesarean delivery, and antiretroviral prophylaxis for the newborn. The goal is to reduce the risk of HIV transmission from mother to child during pregnancy, labor, and breastfeeding.

## **Why the Correct Answer is Right**
The correct approach to prevent HIV transmission from mother to child involves administering antiretroviral drugs to the mother during pregnancy, labor, and to the newborn after birth. This strategy significantly reduces the risk of HIV transmission. The most effective regimen typically includes a combination of antiretroviral drugs.

## **Why Each Wrong Option is Incorrect**
- **Option A:** This option is incorrect because it does not specify the use of antiretroviral therapy, which is the cornerstone of PMTCT.
- **Option B:** This option is incorrect as it also does not provide a comprehensive approach to PMTCT.
- **Option D:** This option is incorrect because it does not include the administration of antiretroviral prophylaxis to the newborn, which is crucial for preventing postnatal transmission.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that the use of **nevirapine** (a non-nucleoside reverse transcriptase inhibitor) as a single dose to the mother at the onset of labor and a single dose to the newborn within 72 hours of birth is an effective and commonly used regimen in resource-limited settings for PMTCT. However, in more resourceful settings, combination antiretroviral therapy is preferred.
