The regimen used for expectant management of placenta previa is –
**Core Concept**
The expectant management of placenta previa involves careful monitoring of the patient to prevent preterm labor and vaginal bleeding, while also ensuring that the fetus is developing normally. This approach is typically recommended for patients with a low-lying placenta, where the placenta covers part of the cervix but does not obstruct the cervical os.
**Why the Correct Answer is Right**
The key principle behind expectant management is to maintain uterine quiescence and prevent preterm labor. This is achieved through bed rest, usually in a hospital setting, to minimize physical activity and prevent uterine contractions. Patients are also closely monitored for signs of vaginal bleeding, preterm labor, or fetal distress. In some cases, a cervical cerclage may be placed to prevent cervical dilation and preterm labor.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not mention any specific management strategy for placenta previa. Expectant management is a specific approach that requires careful monitoring and bed rest.
**Option B:** This option is incorrect because it is too vague and does not provide any clear guidance on how to manage placenta previa. While hospitalization may be necessary, it is not a specific management strategy.
**Option C:** This option is incorrect because it implies surgical intervention, which is not typically recommended for expectant management of placenta previa. Surgery may be necessary in cases of severe bleeding or fetal distress.
**Clinical Pearl / High-Yield Fact**
It's essential to note that the primary goal of expectant management is to prevent preterm labor and vaginal bleeding, while also ensuring fetal well-being. Close monitoring and bed rest are crucial in maintaining uterine quiescence and preventing complications.
**Correct Answer:** A. Bed rest and close monitoring in a hospital setting.
