For a gravida 1, para 0 woman who experienced a spontaneous abortion at 10 weeks, what is the most important Rh-related question?

• A. Did you want this pregnancy?
• B. Do you know if you are Rh-negative or Rh-positive?
• C. Did you have difficulty becoming pregnant?
• D. Did you take any medications while you were pregnant?

Answer: (D)

Rh status and preventing maternal sensitization after exposure to fetal red blood cells is the key issue here. After a spontaneous abortion, if the mother is Rh-negative, fetal Rh-positive blood cells can enter her circulation and trigger the production of anti-D antibodies. Giving Rh immune globulin after the abortion helps prevent that sensitization, reducing the risk of Rh disease in future pregnancies. If the mother is Rh-positive, there is no risk of this type of sensitization, so Rh immune globulin isn’t needed. So, knowing whether the patient is Rh-negative or Rh-positive is the most important Rh-related question. The other questions don’t address Rh incompatibility directly.
