Select the statement that best explains how RhoGAM works.
A) RhoGAM contains anti-Rh antibodies; these bind to any Rh⁺ erythrocytes that may have entered the mother's circulation from an Rh⁺ baby, preventing these RBCs from stimulating a primary immune response in the mother.
B) RhoGAM contains anti-Rh antibodies; these bind to any Rh⁻ erythrocytes that may have entered the mother's circulation from an Rh⁻ baby, preventing these RBCs from stimulating a primary immune response in the mother.
C) RhoGAM contains anti-Rh antibodies; these bind to any Rh⁺ leukocytes that may have entered the mother's circulation from an Rh⁺ baby, preventing these WBCs from stimulating a primary immune response in the mother.
D) RhoGAM contains anti-Rh antibodies; these bind to any Rh⁺ erythrocytes that may have entered the mother's circulation from an Rh⁺ baby, preventing these RBCs from stimulating a secondary immune response in the mother.
E) RhoGAM contains anti-ABO antibodies; these bind to any ABO⁺ erythrocytes that may have entered the mother's circulation from a ABO⁺ baby, preventing these RBCs from stimulating a primary immune response in the mother.

Quizplus · Accepted Answer

RhoGAM contains anti-Rh antibodies that bind to Rh⁺ erythrocytes that may have entered the mother's circulation from an Rh⁺ baby, preventing these RBCs from stimulating a primary immune response in the mother. This prevents the mother's immune system from mounting an attack against any future Rh⁺ fetuses.
