Final answer:
The correct response is Option D: Rh negative and Coombs' negative. This is the required blood type and Coombs' test result for a pregnant woman to receive Rho(D) immune globulin (RhoGAM) after giving birth to prevent hemolytic disease of the newborn (HDN).
Step-by-step explanation:
The blood type and Coombs' test result that a pregnant woman must have to receive Rho(D) immune globulin (RhoGAM) after giving birth is Rh negative and Coombs' negative (Option D: Rh negative and Coombs' negative). RhoGAM is administered to prevent hemolytic disease of the newborn (HDN) by destroying fetal Rh+ erythrocytes that may cross the placental barrier into the bloodstream of an Rh- mother. This mother must not have made anti-Rh antibodies (hence the need for a negative Coombs' test, which checks for these antibodies). The administration of RhoGAM occurs during weeks 26-28 of pregnancy and within 72 hours following the birth, especially after the birth of the first Rh+ child where exposure to Rh+ blood may sensitize the mother. Its use has been pivotal in reducing the occurrence of HDN from about 13-14 percent to 0.1 percent in the United States.
