The nurse is administering RhoGAM to a postpartum client who wants to know how the medication works. The response by the nurse would be based on which of the following physiological concepts? The purpose of RhoGAM administration is:

1. To provide antibodies to destroy foreign fetal red blood cells.

2. To protect the Rh* fetus during a subsequent pregnancy.

3. To provide antibodies against Rh+ blood and prevent immune sensitization.

4. To prevent maternal antibodies from crossing the placenta and destroying fetal white blood cells.
