Question

Quizplus · Accepted Answer

For women who are serologically not immune (titre of 1:8 or enzyme immunoassay level less than 0.8),a subcutaneous injection of rubella vaccine is recommended in the immediate postpartum period.This patient's rubella titre indicates that she is not immune and that she needs to receive a vaccine.These data do not indicate that the patient needs a blood transfusion.Rh immune globulin is indicated only if the patient has a negative Rh status and the infant has a positive Rh status.A Kleihauer-Betke test should be performed if a large fetomaternal transfusion is suspected,especially if the mother is Rh negative.The data do not provide any indication for performing this test.
