Administration of anti-Rh antibodies to the fetus postdelivery, B. Administration of anti-Rh antibodies to the mother postdelivery, C. Immediate blood transfusion of the suspected father, D. Immediate blood transfusion of the mother with Rh-positive blood", 'role': 'user'}, {'content': 'Answer: B \nExplanation: Anti-Rh antibodies (IgG are reactive at 98.6degF ) are the leading cause of hemolytic disease of the newborn (HDN). Currently, Rh immunization can be suppressed in antepartum or postpartum Rh-women if high-titer anti-Rh immunoglobulin (Rh Ig) is administered within 72 hours after the potentially sensitizing dose of Rh+ cells (i.e., the birth of the child). The other choices will do nothing to prevent the development of HDN in future pregnancies.', 'role': 'assistant'}]
