The nurse should ask a patient "Have you ever received a blood transfusion" while observing his health history.
What is a blood transfusion?
It is a life-saving procedure in which donated blood is provided through a narrow tube placed within a vein in the arm. It replaces lost blood during surgery or injury.
Complications of blood transfusion:
- Allergic reactions
- Fever
- Acute immune Hemolytic reaction
- Blood-borne infections
Immune-mediated transfusion reactions occur when incompatible blood is transfused into a patient's blood circulatory system.
If incompatible blood is given in a transfusion, the donor cells are treated as foreign invaders by the immune system which attacks them accordingly.
Compatibility for blood transfusion includes:
- Crossmatch between donor red blood cells and recipient serum.
People with type A blood react against type B or type AB blood.
People with type B blood react against type A or type AB blood
People with type O blood react against type A, type B, or type AB blood.
People with type AB blood will not react against type A, type B, type AB, or type O blood as they are universal donors.
Hence incompatible blood transfusion most probably causes abnormal immune function.
