Q33 - ABO Blood Group Compatibility in Transfusion
In order to make safe blood transfusions, we have to know the blood types of both patient and donor. Mixing incompatible blood types is dangerous and may be lethal. In this problem we consider only the ABO blood group system and transfusions that do not include plasma.
Using the information and data, determine which of the statements are true or which are false.
A. Blood transfusion with A-blood causes an incompatibility reaction in an O-recipient
B. A traffic accident victim needed blood fast, and without knowing the blood group type of the victim the doctor prescribed blood of type O, and the patient showed signs of incompatibility
C. Persons with type AB can receive blood from all ABO types
D. Persons with type B can receive blood of type AB
