Final answer:
RhoGAM is a medication that may be prescribed to a Rh+ mother on bed rest to protect the fetus. It prevents the development of Rh antibodies in the mother's bloodstream, which can harm the fetus. RhoGAM has been proven effective in reducing the risk of HDN.
Step-by-step explanation:
In order to ensure the well-being of the fetus in a mother who is Rh positive and on bed rest, the physician may order a medication called RhoGAM. RhoGAM is a drug that is administered to Rh positive mothers during weeks 26-28 of pregnancy and within 72 hours following birth. It works by temporarily preventing the development of Rh antibodies in the mother's bloodstream, which can potentially harm the fetus. RhoGAM has been proven effective in decreasing the incidence of Hemolytic Disease of the Newborn (HDN), a condition that can occur when the mother's Rh antibodies attack the fetal Rh-positive red blood cells.
