Which type of blood can be donated and safely administered to the patient with type O negative blood?
- O positive
Type O positive blood could potentially cause a reaction for the patient with type O negative blood.
- O negative
Individuals with type O negative blood have no antigens. While this individual can donate blood to all patients regardless of blood type, they can only receive type O negative blood to avoid the risk of experiencing a potentially life-threatening transfusion reaction.
- AB positive
Type AB positive blood is not safe to administer to the patient with type O negative blood.
- AB negative
Type AB negative blood cannot be safely administered to the patient with type O negative blood.
An individual blood type is classified by the absence, or presence, of antibodies and inherited substances located on the surface of RBCs.
Individuals with type O blood have no antigens; therefore, they are the universal donor. Rh factor also plays a role in compatibility. Rh factor is a protein; those who have it are Rh positive and those without it are Rh negative. Therefore, an individual with type O negative blood can only receive blood from an individual with the same exact blood type to avoid a potentially life-threatening transfusion reaction.
Test Taking Tip
Consider the different blood types and how they are classified, including antibodies, antigens, and proteins when determining the correct choice for this question.
