Erythroblastosis fetalis can be avoided by administering _______ to the mother immediately after the delivery of the first child. Fill the blank with appropriate option

Solution:

Erythroblastosis fetalis is a condition that can occur when an Rh-negative mother carries an Rh-positive fetus. During the delivery of the first Rh-positive child, some fetal Rh-positive red blood cells may enter the mother's bloodstream, sensitizing her immune system to produce anti-Rh antibodies. To prevent this sensitization and thus avoid erythroblastosis fetalis in subsequent Rh-positive pregnancies, the mother is administered anti-Rh antibodies (e.g., RhoGAM) immediately after the delivery of the first child. These administered antibodies destroy any fetal Rh-positive red blood cells that have entered the mother's circulation before her own immune system can mount a primary immune response and produce its own antibodies.
