RhoGAM injection [one brand of Rh immunoglobulin] is given to Rh-negative mothers to:
1. initiate the synthesis of anti-Rh antibodies in the mother.
2. initiate anti-Rh antibody production in the fetus.
3. prevent the mother from producing anti-Rh antibodies.
4. prevent the fetus from producing anti-Rh antibodies.

An Rh + woman is pregnant with an Rh- fetus. The consequences can be:
1. There is usually no risk during the first pregnancy, but it can harm the fetus during a subsequent pregnancy if the mother is not treated.
2. It always poses a serious risk to the fetus, even in the first pregnancy.
3. Only in rare cases is there a risk to the fetus during the first pregnancy.
4. There is no risk to the fetus when a woman who is Rh+ carries an Rh- fetus.

What is true regarding blood transfusion and compatibility?
1. A-negative blood can probably be safely donated to a person with A-positive blood.
2. Antibodies against the Rh antigen do not develop unless an Rh-positive person is exposed to Rh-negative blood.
3. The largest percentage of people in India are Rh-negative.
4. Rh-negative mothers cannot have an Rh-positive baby.
