Review Antenatal complications related questions and content

Fraternal twins are delivered by your Rh-negative patient. Twin A is Rh-positive and twin B is Rh-negative. Prior to administering Rho(D) immune globulin (RhoGAM), the nurse should determine the results of the

  • A. direct Coombs test of twin A.
  • B. direct Coombs test of twin B.
  • C. indirect Coombs test of the mother.
  • D. transcutaneous bilirubin level for both twins.
Correct Answer: C

Rationale: The correct answer is C, indirect Coombs test of the mother. This test is crucial to determine if the mother has developed antibodies against the Rh-positive blood of twin A. If the test is positive, it indicates sensitization has occurred, making RhoGAM necessary to prevent hemolytic disease in future pregnancies. Direct Coombs tests of the twins (choices A and B) are not relevant in this scenario as they assess for antibodies already attached to the red blood cells. Transcutaneous bilirubin levels (choice D) are used to monitor jaundice, not Rh incompatibility.
