Question

rh immunoglobulin (rho - gam) __________.
a is used to prevent hemolytic disease of the newborn
b contains anti - rh antibodies
c contains rh factors
d is used to prevent hemolytic disease of the newborn and contains anti - rh antibodies

Explanation:

• Option A: Rh immunoglobulin (Rho - Gam) is indeed used to prevent hemolytic disease of the newborn. When an Rh - negative mother is exposed to Rh - positive fetal blood (e.g., during childbirth), Rho - Gam can prevent her from developing antibodies against the Rh factor, which could harm future Rh - positive fetuses.
• Option B: Rho - Gam contains anti - Rh antibodies. These antibodies work by binding to Rh - positive red blood cells in the mother's circulation (if any from the fetus) and clearing them before the mother's immune system can mount a significant response and produce her own anti - Rh antibodies.
• Option C: Rho - Gam does not contain Rh factors. If it did, it would be counterproductive as it would expose the Rh - negative mother to Rh antigens, which is what we are trying to prevent.
• Option D: Since both A and B are correct, this option that combines them is also correct.

Answer:

D. Is used to prevent hemolytic disease of the newborn and contains anti - Rh antibodies
