A woman with type B- blood type experiences a miscarriage during the 10th week of her first pregnancy. The blood type of the father is unknown at the time. Should fetal hemolytic disease be of sufficient concern to administer Rhogam (anti-Rh antibodies)?
1) Yes; without knowing the blood type of the father, the fetus may have been Rh+ which could impact future pregnancies.
2) Yes; Rhogam should always be administered after a miscarriage, no matter what the mother's blood type.
3) No; Rhogam should be given to women with Rh+ positive blood types to prevent hemolysis in Rh- fetuses.
4) No; the risks of administering Rhogam are typically outweighed by the benefits to the mother.
