The nurse gives a 35-year-old primigravida client a RhoGAM injection in her 27th week of pregnancy. Which of the following client situations requires the nurse to take this action?

  • Rh-negative mother and Rh-positive father
  • Rh-negative mother and Rh-negative father
  • Rh-positive mother and Rh-negative father
  • Rh-positive mother and Rh-positive father
Number 1 is correct.
Problems occur during pregnancy when the mother is Rh-negative and is exposed to Rh-positive fetal blood (via a Rh-positive father). Administration of RhoGAM to the Rh-negative woman with a Rh-positive father is done twice, once between 26 and 28 weeks of pregnancy and again within 72 hours of birth.
