Please read the clinical scenario, and then answer the question that follow to become familiar with the traditional NCLEX question format.
Marian is a 28-year-old woman who is 30 weeks' pregnant with her second child. Her first pregnancy and delivery was uncomplicated, and she now has a healthy 2-year-old girl. However, it is known that she is Rh-, and this child could be at risk for hemolytic disease of the newborn. She did receive RhoGAM with her first pregnancy. She presents to your maternal-fetal medicine clinic for a checkup, as she is a medium-risk pregnant mom.
-After further investigation,it is learned that the father is Rh+,and so was the first child.However,Marian declines the RhoGAM injection because "there were no complications with my first pregnancy and delivery,how can you be sure there will be with this one?" Plus,she also explains how unpleasant the RhoGAM injection was with her first pregnancy,and she would like to avoid it,if at all possible.What is an appropriate response?

A) "I didn't realize you received RhoGAM with your first pregnancy.There's a good chance you don't need it this time after all."
B) "It is important you receive your RhoGAM injection,because this child will probably develop hemolytic disease of the newborn if you don't."
C) "It is important that we keep you from being sensitized to Rh factor,otherwise future pregnancies will be at risk for developing hemolytic disease of the newborn."
D) "You were probably sensitized to Rh factor with your first pregnancy,so the chances are decreased that this child will develop hemolytic disease of the newborn.I'll ask the doctor if we can forego the injection."
