A nurse is teaching a client who is postpartum and has a new prescription for an injection of Rho (D) immunoglobulin. Which of the following should be included in the teaching?

A. It prevents the formation of Rh antibodies in mothers who are Rh negative: Rho(D) immunoglobulin is given to Rh-negative mothers after delivery of an Rh-positive newborn to prevent sensitization. It works by destroying fetal Rh-positive red blood cells in the maternal circulation before the mother can form antibodies, protecting future pregnancies. B. It prevents the formation of Rh antibodies in newborns who are Rh positive: The newborn is not the target of Rho(D) immunoglobulin. The medication is administered to the mother, not the infant. C. It destroys Rh antibodies in newborns who are Rh positive: The injection does not act on antibodies already formed in anyone; it prevents the maternal immune system from forming them. D. It destroys Rh antibodies in mothers who are Rh negative: Rho(D) does not destroy existing antibodies; it prevents their formation.
