An Rh –ve person, when exposed to Rh +ve blood:
| 1. | will form antibodies against the Rh antigen |
| 2. | will be unaffected |
| 3. | will form antibodies against the Rh antigen only on second exposure |
| 4. | will receive anti Rh antibodies from the donor |
A person has type A antigen on RBC and anti-B antibodies in plasma. He can receive blood from a person with blood group:
| 1. | A and O | 2. | AB, A, B and O |
| 3. | B and O | 4. | Only O |
To prevent eryhtroblastosis fetalis in future pregnancies:
| 1. | Anti-Rh Immunoglobulins must be given to Rh –ve mothers at the time of each delivery |
| 2. | Anti-Rh Immunoglobulins must be given to new born at the time of each delivery |
| 3. | Rh Antigens must be given to new born at the time of each delivery |
| 4. | Anti Antigens must be given to Rh –ve mothers at the time of each delivery |
What is true for the blood Type O?
| 1. | It is universal donor because it has neither anti-A antibodies nor anti-B antibodies circulating in the plasma. |
| 2. | It is universal donor because it has neither antigen A nor antigen B on its RBCs. |
| 3. | It is universal recipient because it has neither anti-A antibodies nor anti-B antibodies circulating in the plasma. |
| 4. | It is universal recipient because it has neither antigen A nor antigen B on its RBCs. |
