Final answer:
A C-section for Placenta Previa may be delayed in order to administer medication to either aid in fetal lung maturity or to manage and stabilize the mother's condition before the surgery.
Step-by-step explanation:
In the case of Placenta Previa, if a surgeon delays doing a C-section, it is usually due to a) fetal distress. If a surgeon delays doing a C-section for Placenta Previa, it is due to the need to administer medication. Placenta Previa occurs when the placenta partially or completely covers the opening of the cervix, and is a condition that can lead to antepartum hemorrhage. The administration of medication prior to a C-section delivery is done in order to enhance fetal lung maturity or to manage the mother's conditions and stabilize the situation before proceeding with major abdominal surgery.
It is important to note that the delaying a C-section for reasons such as fetal distress would be counterproductive, as C-section is often performed urgently in cases of fetal distress. A maternal request is not typically a reason to delay a necessary C-section, and waiting for full dilation is not relevant for a C-section, as full dilation is needed for vaginal delivery, not surgical delivery.
