Quizplus · Accepted Answer

If an Rh-negative woman with an Rh-positive fetus has been exposed to Rh-positive blood through previous transfusions, she may develop antibodies against the Rh antigen.

Therefore, multiple Rh-positive blood transfusions increase the risk of developing this condition in subsequent pregnancies.
