______ population has Rh ______ on the surface of ______ present in their ______.

(3) 80%, antibody, platelet, plasma

(4) 20%, antibody, RBC, blood

Hemolytic disease of the newborn (HDN) may occur in the feotus of a second pregnancy if:

1. The mother is ${\mathrm{Rh}}^{+}$ and the baby is ${\mathrm{Rh}}^{-}$

2. The mother is ${\mathrm{Rh}}^{+}$ and the baby is ${\mathrm{Rh}}^{+}$

3. The mother is ${\mathrm{Rh}}^{-}$ and the baby is ${\mathrm{Rh}}^{-}$

4. The mother is ${\mathrm{Rh}}^{-}$ and the baby is ${\mathrm{Rh}}^{+}$

To avoid Erythroblastosis Foetalis–

(1) the mother is administered anti–Rh antibodies.

(2) the baby is administered Rh antibodies.

(3) the mother is administered Rh antibodies

(4) the baby is administered anti–Rh antibodies

There is a possibility of exposure of the maternal blood [of Rh -ve mother] to small amounts of Rh +ve blood from the fetus during the:

1. First trimester of any pregnancy

2. Third trimester of the second pregnancy only

3. Delivery of the child

4. There is no such possibility

During ‘Erythroblastosis fetalis’ there is
1. Foetal stem cells fails to form RBC.
2. RBC fails to transport O₂ to foetal tissues.
3. Agglutination and phagocytosis of RBC.
4. RBC fails to develop Rh antigen on its surface

A person can receive blood only from a donor of his/her blood group if the blood group of this person is:

1. O

2. AB

3. A or B

4. A, B, AB or O

Erythroblastosis fetalis can be prevented during a second pregnancy in a Rh negative mother who is likely to carry a Rh positive fetus by:

Erythroblastosis foetalis occurs when a factor from mother passes into the foetus through the placenta. The factor is 

1. Rh antigen

2. Rh antibodies

3. Agglutinins

4. ABO antibodies

Match the following:
