What is the purpose of RhoGAM for Rh-negative mothers?

RhoGAM serves a specific and critical purpose for Rh-negative mothers by preventing the formation of antibodies against fetal blood cells, particularly in situations where an Rh-positive fetus is present. When an Rh-negative mother carries an Rh-positive baby, there is a risk that the mother’s immune system may recognize the Rh-positive blood cells as foreign and start to produce antibodies against them. This can lead to hemolytic disease of the newborn (HDN) in future pregnancies if those antibodies cross the placenta and attack the red blood cells of an Rh-positive baby.

The administration of RhoGAM is a preventive measure. By providing this immunoglobulin injection, it effectively clears any Rh-positive fetal blood cells that may enter the maternal circulation, thus preventing the mother's immune system from becoming sensitized and producing those harmful antibodies.

The other options do not align with the purpose of RhoGAM. It is not used to treat infections, prevent uterine contractions, or assist in breastfeeding, which indicates the focused and crucial role RhoGAM plays in maternal-fetal medicine, particularly regarding Rh incompatibility issues.
