## **Core Concept**
Expectant management of placenta previa involves a conservative approach to manage the condition without immediate delivery, aiming to prolong pregnancy until fetal maturity is achieved or a suitable gestational age for delivery is reached. This approach requires careful monitoring and specific interventions to prevent complications.

## **Why the Correct Answer is Right**
The correct answer, , involves understanding what is generally recommended and safe during the expectant management of placenta previa. This includes bed rest, close monitoring of maternal and fetal well-being, and readiness for immediate delivery if there's significant bleeding. The management strategy often involves avoiding activities that could provoke bleeding.

## **Why Each Wrong Option is Incorrect**
- **Option A:** is a part of expectant management as it helps in reducing physical activity, which can potentially reduce the risk of bleeding.
- **Option B:** is also considered because corticosteroids can be administered to enhance fetal lung maturity if delivery is planned before fetal maturity is achieved.
- **Option C:** might seem appropriate but could be incorrect depending on what it entails; however, without specifics, it's hard to judge its appropriateness directly.
- **Option D:** is incorrect because immediate delivery is typically reserved for cases of severe bleeding or when the pregnancy is at a gestational age where delivery is safer than continuing expectant management.

## **Clinical Pearl / High-Yield Fact**
A key point in managing placenta previa expectantly is to avoid provoking factors for bleeding, such as coitus, heavy lifting, or vigorous physical activity. Tocolytic agents might sometimes be used to manage preterm labor if it occurs, but their use must be balanced against the potential risks.

## **Correct Answer:** D. Immediate delivery.
