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

After examining the blood groups of husband and wife, the doctor advised them not to have more than one child. The blood groups of the couple are likely to be

(1)  Male Rh^- and Female Rh⁺

(2)  Male Rh⁺ and Female Rh⁺

(3)  Male Rh⁺ and Female Rh^-

(4)  Male Rh^- and Female Rh^-

The condition of erythroblastosis foetalis is–

(1) Rh^– female and Rh⁺ male with first Rh⁺ baby

(2) Rh⁺ female and Rh⁺ male with first Rh^– baby

(3) Rh⁺ female and Rh^– male with first Rh^– baby

(4) Rh^– female and Rh^– male with first Rh⁺ baby

Match the following:

1. p–g; q–h; r–e; s–f

2. p–f; q–e; r–h; s–g

3. p–e; q–h; r–f; s–g

4. p–f; q–g; r–h; s–e

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

(1) 20%, antigen, platelets, plasma

(2) 80%, antigen, RBC, blood

(3) 80%, antibody, platelet, plasma

(4) 20%, antibody, RBC, blood

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

'Erythroblastosis Foetails' occurs when:

I.   Mother is Rh⁺ and foetus is Rh^-.

II.  Mother is Rh^- and foetus is Rh⁺.

III. Mother and foetus both are Rh⁺.

IV.  Mother and foetus both are Rh^-.

1.  I & II

2.  Only I

3.  Only II

4.  II, III & IV

Rh-factor can produce disease:

1. AIDS

2. Turner's syndrome

3. Erythroblastosis foetalis

4. Sickle cell anaemia

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 fetalis condition arises when a:

1. Rh (+) female carries a Rh(–) foetus for the
first time.

2. Rh (+) female carries a Rh(–) foetus for the
second time.

3. Rh (–) female carries a Rh (+) foetus for the
first time.

4. Rh (–) female carries a Rh (+) foetus for the
second time.
