Final answer:
RhoGAM is a medication used to prevent Rh incompatibility and the development of hemolytic disease of the newborn (HDN). It is given to Rh mothers during pregnancy and after birth to prevent the mother's immune system from developing antibodies against the fetus's Rh-positive blood cells.
Step-by-step explanation:
RhoGAM, short for Rh immune globulin, is a medication used to prevent Rh incompatibility. Rh incompatibility occurs when a Rh-negative mother carries a Rh-positive fetus, which can lead to hemolytic disease of the newborn (HDN). RhoGAM is given to Rh mothers during pregnancy and after birth to prevent the mother's immune system from developing antibodies against the fetus's Rh-positive blood cells, thus reducing the risk of HDN.
