Question

Which of the following steps is taken to prevent the occurrence of erythroblastosis fetalis?

• A. Blood transfusion in mother
• B. Treating the mother with anti Rh antibodies
• C. Aborting the second pregnancy
• D. None of the above

Answer 1

The correct option is B

Treating the mother with anti Rh antibodies

Erythroblastosis fetalis can be prevented by giving the mother anti Rh antibodies. These antibodies attach to the Rh antigens now circulating in the mother’s bloodstream and prevent her own immune cells from recognising the antigen. This in turn prevents the mother from forming her own antibodies against the Rh antigen, protecting the next child from Rh incompatibility related disease.
