An Rh-negative pregnant woman has no detectable anti-D antibodies and experiences abdominal trauma. Why may anti-D immunoglobulin be prescribed after assessment?
Correct answer: B. To prevent maternal Rh sensitisation
- A. To destroy maternal platelets
- B. To prevent maternal Rh sensitisation
- C. To increase fetal red-cell production
- D. To treat established fetal anaemia
Explanation
Abdominal trauma can allow fetal red cells to enter the maternal circulation. Anti-D immunoglobulin prevents the Rh-negative mother from forming antibodies that could harm an Rh-positive fetus in this or a later pregnancy.
