Question

When patient information is unavailable in an emergency, which blood type can be given immediately?

1) A
2) B
3) AB
4) O

Answer 1

Type O blood is the universal donor and can be transfused immediately in emergencies when patient information is unavailable.

Step-by-step explanation:

Type O blood is the universal donor and can be transfused immediately in emergencies when patient information is unavailable. When patient information is unavailable in an emergency, the blood type that can be given immediately is type O. People with type O blood do not have any antigens on their RBCs, which means that their blood can be transfused to people with blood types A, B, or AB without causing an antibody reaction. In an emergency where there is a severe threat to life and no time for cross matching, type O blood is considered the universal donor and is the safest option for transfusion.
