Write answer in between .Q:A 30-year-old woman presents to her new doctor at 27 weeks gestation with her second pregnancy. Her blood type is B- and the father of the child is B. Her first child had an Apgar score of 7 at 1 minute and 9 at 5 minutes and has a B blood type. The fetus has a heart rate of 130min and blood pressure of 10058 mm Hg. There is a concern that the fetus may develop erythroblastosis fetalis EF. Which of the following statements is true about erythroblastosis fetalis?? A: Can occur with an Rh-negative mother and Rh-positive father., B: RhoD immune globulin should be administered during the first trimester., C: The first child will always be affected, as well as all subsequent pregnancies., D: The combination of an Rh-positive mother and an Rh-negative fetus will cause the condition., E: In EF, IgM crosses the placenta and causes erythrocyte hemolysis in the fetus.,  <response>: This is a question about erythroblastosis fetalis EF, which can occur when an Rh-negative mother is pregnant with an Rh-positive fetus. The key facts in the stem are that the mother is Rh-negative blood type B-, the father and previous child are Rh-positive blood types B, and there is concern about the current Rh-positive fetus developing EF. Choice A is correct, as EF can occur when an Rh-negative mother has an Rh-positive fetus, which allows Rh-positive fetal blood cells to cross into the maternal circulation and trigger an immune response. Choice B is incorrect, as RhoD immune globulin is given at 28 weeks gestation and after delivery of an Rh-positive infant, not during the first trimester. Choice C is incorrect because typically only second and subsequent pregnancies are affected, not the first child. Choice D is incorrect because an Rh-positive mother and Rh-negative fetus does not cause EF. Choice E is incorrect because in EF it is IgG antibodies, not IgM, that cross the placenta and cause hemolysis.A: Can occur with an Rh-negative mother and Rh-positive father.
