Rhogam is most often used to treat____ mothers that have a ____ infant.
A. RH positive, RH positive
B. RH positive, RH negative
C. RH negative, RH positive
D. RH negative, RH negative
Correct Answer: C. RH negative, RH positive
Rhogam prevents the production of anti-RH antibodies in the mother that has an Rh-positive fetus.
Option A: RhoGAM is a prescription medicine that is used to prevent Rh immunization, a condition in which an individual with Rh-negative blood develops antibodies after exposure to Rh-positive blood.
Option B: If the father or baby is not conclusively shown to be Rh-negative, RhoGAM should be given to an Rh-negative mother in the following clinical situations to prevent Rh immunization: after delivery of an Rh-positive baby; routine prevention of Rh immunization at 26 to 28 weeks of pregnancy; maternal or fetal bleeding during pregnancy from certain conditions; or an actual or threatened pregnancy loss at any stage.
Option D: It isn’t until second and subsequent pregnancies when antibodies are already built up, that Rh incompatibility can cause problems. Indeed, these antibodies can cross the placenta and attack the baby’s red blood cells. This can cause the baby to develop anemia, and in severe cases, result in miscarriage.
