25 years old 2nd gravida with B negative blood group reaches in labour room in full dilatation. All the following norms to be followed except
**Core Concept**
The question is testing the knowledge of blood group compatibility in obstetrics. The underlying principle is that Rh-negative mothers should receive Rh immunoglobulin (RhIg) to prevent isoimmunization and subsequent hemolytic disease of the newborn (HDN) if they are exposed to Rh-positive blood during delivery.
**Why the Correct Answer is Right**
In a Rh-negative mother, Rh immunoglobulin is administered to prevent the formation of anti-Rh antibodies. This is crucial because if the mother is exposed to Rh-positive fetal blood during delivery, the anti-Rh antibodies can cross the placenta and destroy the fetus's red blood cells, leading to HDN. The administration of RhIg at 28 weeks of gestation and within 72 hours of delivery is a standard practice in obstetrics.
