Hemolytic disease of the newborn could result from which one of the following situations?Group of answer choicesmother is Rh-; fetus is Rh-mother is Rh+; fetus is Rh-mother is Rh-; fetus is Rh+mother is Rh+; fetus is Rh+
Solution
Hemolytic disease of the newborn could result from the situation where the mother is Rh- and the fetus is Rh+.
Here's why:
-
Rh factor is a protein found on red blood cells. Some people have this protein (they are Rh positive) and others do not (they are Rh negative).
-
If a woman who is Rh negative becomes pregnant with a fetus that is Rh positive, she may become sensitized to the Rh factor, meaning her body may produce antibodies against it.
-
This usually isn't a problem in a first pregnancy, because the baby is often born before many of these antibodies develop. However, these antibodies stay in the mother's body once they have formed.
-
In a second pregnancy, if the new baby is also Rh positive, these antibodies can cross the placenta and attack the baby's red blood cells, leading to hemolytic disease of the newborn.
So, the situation where the mother is Rh- and the fetus is Rh+ could potentially lead to hemolytic disease of the newborn.
