Which management step is crucial for a patient with diagnosed placenta previa?

The administration of steroids for fetal lung maturity is a crucial management step for a patient with diagnosed placenta previa. In cases where there is a risk of preterm delivery due to placenta previa, the administration of glucocorticoids can significantly improve neonatal outcomes. Steroids help accelerate the maturation of the fetal lungs, reducing the risk of complications like respiratory distress syndrome if the baby is born prematurely. This is particularly important because patients with placenta previa may face the likelihood of a preterm birth either due to complications or the need for early delivery.

Other management options would not align with the guidelines for managing placenta previa. For instance, immediate cesarean delivery is typically indicated only if there are significant maternal or fetal concerns, such as significant bleeding or fetal distress, rather than as a routine step. Digital vaginal exams are contraindicated in cases of placenta previa because they can provoke bleeding and other complications. Encouraging sexual activity is inappropriate since it can also lead to bleeding and increase the risk of harm to both the mother and fetus. Thus, timely administration of steroids stands out as a proactive measure in this specific clinical situation.
