**Core Concept**
Placenta previa is a condition in pregnancy where the placenta partially or completely covers the internal cervical os. This can lead to severe bleeding during pregnancy or labor, posing a significant risk to both mother and fetus.

**Why the Correct Answer is Right**
In cases of placenta previa with heavy bleeding, the priority is to stabilize the mother and prevent further blood loss. The correct management involves administering corticosteroids to promote fetal lung maturity, administering betamethasone to reduce the risk of respiratory distress syndrome, and preparing for immediate delivery. However, the correct answer is not related to these options, but rather the best course of action is to administer **uterine tamponade** or **uterine compression sutures** to control the bleeding, and then proceed with cesarean delivery in a controlled setting.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it doesn't address the immediate need to control the bleeding in a placenta previa with heavy bleeding.
**Option B:** This option is incorrect because it doesn't directly address the management of placenta previa with heavy bleeding.
**Option C:** This option is incorrect because it's a treatment for other conditions and not directly related to placenta previa management.
**Option D:** This option is incorrect because it's a treatment for preterm labor and not directly related to placenta previa management.

**Clinical Pearl / High-Yield Fact**
In cases of placenta previa with heavy bleeding, the key is to prioritize maternal stabilization and control of bleeding before proceeding with delivery. Uterine tamponade or compression sutures can be life-saving in these situations.

**Correct Answer:**
A. Administering uterine tamponade or compression sutures to control the bleeding.
