Rhesus Factor Incompatibility

A potential problem with a rhesus negative mother.

If a Rhesus negative woman is exposed to Rhesus positive blood as a result of syringe sharing, the resultant Rhesus factor antibodies will be;
a. Ig A
b. Ig B
c. Ig F
d. Ig G *

Haemolytic disease of the new-born is a possibility when:
a. Mother is Rhesus positive and father is Rhesus negative
b. Mother is Rhesus positive and father is Rhesus positive
c. Mother is Rhesus negative and father is Rhesus negative
d. Mother is Rhesus negative and father is Rhesus positive *

If a mother is carrying Rhesus factor antibodies in her plasma and her foetus is
Rhesus factor positive then:
a. Maternal Rhesus factor antibodies will cause agglutination of maternal red blood
cells
c. Maternal Rhesus factor antibodies will not cross the placenta in to the foetus
c. Maternal Rhesus factor antibodies will cross the placenta in to the foetus
d. None of the above
