What is the nursing action after a Rh negative client expels total products of conception at 12 weeks' gestation and is confirmed not sensitized?

Administering Rho(D) immune globulin within 72 hours is crucial for Rh-negative patients who have experienced a miscarriage or abortion, even if they are confirmed not to be sensitized. The purpose of Rho(D) immune globulin is to prevent Rh alloimmunization in future pregnancies. If an Rh-negative person is exposed to Rh-positive fetal blood, the immune system may produce antibodies against Rh-positive blood cells, which can lead to complications in subsequent pregnancies.

In situations where the miscarriage occurs before 13 weeks and is confirmed that the mother is not sensitized, administering Rho(D) immune globulin helps ensure that any Rh-positive cells that may have entered the maternal circulation do not trigger an immune response. This proactive measure significantly decreases the risk of hemolytic disease of the newborn in future pregnancies.

The other options, while potentially relevant in specific contexts, do not directly address the immediate need for preventing Rh sensitization. Follow-up ultrasounds, hormone replacement, and scheduling CBC tests are important in various scenarios but do not fulfill the urgent requirement to manage Rh status effectively.
