Question

Quizplus · Accepted Answer

Sensitization to Rh antigen can occur during delivery, miscarriage or abortion, leading to the production of anti-Rh antibodies in a subsequent pregnancy. This can cause hemolytic disease of the newborn, which can be prevented by administering Rh immunoglobulin to the mother during and after the pregnancy. A is incorrect because a person's serum should not have IgM against their own red blood cells. B is incorrect because transfusion reactions are still a concern, especially in cases of incompatible blood type. C is incorrect because hemolytic disease of the newborn can be prevented as mentioned above.
