Final answer:
Proper identification for a blood transfusion involves confirming the client's verbal identification and checking their ID bracelet against the blood label, sometimes with a secondary nurse confirmation. Universal donor O negative blood is used in urgent situations without a known blood type, and blood type AB is characterized by agglutination with both anti-A and anti-B serums. Hence, option B Check the client's identification bracelet against the blood product label is correct answer.
Step-by-step explanation:
To ensure proper client identification before administering a blood transfusion, the nurse should follow several steps. First, the client should be asked to state their name and date of birth. Second, the nurse should check the client's identification bracelet against the blood product label to ensure a match.
Third, it is a common practice to confirm the information with another nurse to proceed with the transfusion securely. Verifying the client's identity solely by looking at the room number is not sufficient. In case of a critical situation where there is no time for determining the patient's blood type, type O negative blood is transfused, as it is considered the universal donor and can be received by individuals of any blood type without causing adverse reactions.
During routine preparations, such as for a scheduled surgery, cross-matching and antibody screening tests are essential to prevent potentially life-threatening transfusion reactions. When a patient's blood sample agglutinates with anti-A and anti-B serum, it indicates they have blood type AB.
Hence, option B Check the client's identification bracelet against the blood product label is correct answer.
