Explain what Rh factor is.
How is it treated?
Rh is a protein on the surface of RBCs. If you have the protein, you're Rh +. You're negative if your RBC does not have the protein.
If the mother and baby have different results, (e.g., mom: neg; baby's father: pos)
During delivery, if your baby is Rh+ and you're Rh-, and if the baby's blood enters your bloodstream, you may develop Ab for Rh+ RBCs.
For the next baby, your body may attack the baby if it is Rh+, leading to life-threatening anemia.
Treatment involves an injection of Rh immune globulin to inhibit the production of Rh Ab during pregnancy.
