52.What is the recommended regimen for anti-D prophylaxis for a 26-year-olc I Rhesus D negative woman who is not sensitized? A. 500 IU Ig at 28 weeks of gestation B. 500 IU lg anti-D at 34 weeks of gestation C. 1000 IU Ig anti -D at 28 weeks gestation D. 1500 IU Ig anti-D at 28 weeks gestation 53. A 20-year-old RhD negative woman presents with bleeding at 11 weeks of gestation. When will you consider administering anti-D lg prophylaxis to this woman? A. She goes on to have a complete miscarriage B. The bleeding is heavy but is stopping C. The bleeding is repetitive or associatec I with pain D. The bleeding is small and painless

52. The correct answer is B. 500 IU Ig anti-D at 34 weeks of gestation.<br /><br />Anti-D prophylaxis is recommended for Rh-negative women to prevent the development of antibodies against the D antigen during pregnancy. The recommended regimen for anti-D prophylaxis for a 26-year-old Rh-negative woman who is not sensitized is to administer 500 IU of intramuscular anti-D immunoglobulin (Ig) at 34 weeks of gestation. This is done to prevent the woman's immune system from producing antibodies against the D antigen if the fetus is Rh-positive.<br /><br />53. The correct answer is C. The bleeding is repetitive or associated with pain.<br /><br />Anti-D Ig prophylaxis is considered for a Rh-negative woman who presents with bleeding during pregnancy if the bleeding is repetitive or associated with pain. This is because repetitive or painful bleeding may indicate a higher risk of fetal-maternal hemorrhage and the potential for sensitization. In such cases, anti-D Ig prophylaxis is administered to prevent the development of antibodies against the D antigen.
