Question

The nurse provides care for a client who requires an emergency blood transfusion. Which blood type can be administered to the client with type B negative blood if type specific is not available?

Answers

  1. B positive
    • Rationale:

      A recipient who does not have the Rh factor will likely have a reaction if given blood with said factor; therefore, this is not the blood administered to the client who is type B negative.

  2. O positive
    • Rationale:

      While type O blood lacks A and B glycoproteins, the positive indicates the presence of the Rh factor which increases the likelihood of a transfusion reaction for those without said antigen; therefore, this is not the blood administered to the client who is type B negative.

  3. A negative
    • Rationale:

      Type A blood cannot be administered to a client who has type B blood due to the A glycoprotein. In addition, type A positive blood contains the Rh factor which increases the likelihood of a transfusion reaction for those without said antigen; therefore, this is not the blood administered to the client who is type B negative.

  4. O negative
    • Rationale:

      Type O negative blood is the universal donor; therefore, it is safe to administer this blood to the client who is type B negative if type specific blood is not available.

Overview

An individual blood type is classified by the absence, or presence, of antibodies and inherited substances located on the surface of RBCs.

Explanation

Learning Outcomes

Individuals with type O negative blood are considered the universal donor because they lack all antigens in their red blood cells (RBCs). When type specific blood is not available, individuals with type B negative blood can receive type O negative blood. However, if type specific blood is available that is the best option to decrease the risk for transfusion reactions.

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.
