Question

Quizplus · Accepted Answer

Sensitization to Rh antigens can occur during delivery, miscarriage, or abortion, leading to the production of IgG antibodies against Rh antigens in the mother's serum. If a subsequent pregnancy involves an Rh-positive fetus, the mother's Rh antibodies can cross the placenta and cause hemolytic disease of the newborn. Adequate anti-Rh immunoglobulin given to the mother can prevent sensitization and subsequent hemolytic disease of the newborn. The other statements are incorrect.
