Question

Which of the following mom-baby combinations is most apt to induce erythroblastosis fetalis?
A) Mom A(-), baby A(+)
B) Mom A(-), baby O(-)
C) Mom A(+), baby A(-)
D) Mom A(+), baby A(+)

Accepted Answer

Erythroblastosis fetalis occurs when the mother's blood type is Rh-negative and the baby's blood type is Rh-positive. In this scenario, the mother's immune system may produce antibodies against the baby's Rh-positive red blood cells, leading to hemolytic disease of the newborn. Choice A) Mom A(-), baby A(+) represents this situation.
