## **Core Concept**
The management of an HIV-positive pregnant woman involves a multidisciplinary approach to prevent mother-to-child transmission (MTCT) of HIV and to manage the mother's health. The key principle is to start antiretroviral therapy (ART) as soon as possible to suppress the viral load.

## **Why the Correct Answer is Right**
The correct approach in managing an HIV-positive pregnant woman detected in the first trimester is to immediately initiate antiretroviral therapy (ART). This is because ART has been shown to significantly reduce the risk of mother-to-child transmission of HIV. The goal is to achieve an undetectable viral load, which greatly reduces the risk of transmission to the infant. The choice of ART regimen is critical, and it should be guided by current guidelines, which often recommend a combination of antiretroviral drugs.

## **Why Each Wrong Option is Incorrect**
- **Option A:** This option is incorrect because it does not specify the initiation of ART, which is the standard of care for pregnant women with HIV to prevent MTCT.
- **Option B:** Similarly, this option is incorrect for the same reason; it lacks specificity regarding the initiation of ART.
- **Option C:** This option might suggest delaying treatment or not initiating ART immediately, which is not in line with current recommendations for pregnant women with HIV.

## **Clinical Pearl / High-Yield Fact**
A crucial point to remember is that the goal of ART in pregnancy is not only to treat the mother's HIV infection but also to prevent MTCT. The regimen chosen should be effective, safe for both the mother and the fetus, and should aim to achieve viral suppression by the time of delivery. Pregnant women with HIV should be managed by a multidisciplinary team including obstetricians, infectious disease specialists, and other healthcare providers.

## **Correct Answer:** D. Start ART immediately.
