When should anti-D immunoglobulin be administered after delivery?
A Within 24 hours
B Within 72 hours
C After 1 week
D Only if symptoms develop
Solution
Correct Answer: Option B
The anti-D immunoglobulin neutralizes any RhD-positive antigens that may have entered the mother's blood during pregnancy. If the antigens have been neutralized, the mother's blood won't produce antibodies.
