A 6-year-old child with β-thalassemia major is scheduled for regular blood transfusions. Which nursing intervention is the priority before administering the blood transfusion?

Patient safety is the highest priority in blood transfusion administration. Proper patient identification and blood compatibility verification prevent potentially fatal transfusion reactions.

Transfusion safety requires meticulous attention to patient identification and blood product verification, and is essential to prevent potentially fatal hemolytic transfusion reactions. The most critical nursing intervention before any transfusion is proper patient identification using two patient identifiers (such as name and date of birth) and blood compatibility verification through cross-checking with another qualified nurse.

Children with β-thalassemia major require regular blood transfusions every 2-4 weeks to maintain adequate hemoglobin levels and prevent complications such as growth retardation, bone deformities, and organ dysfunction. These patients are at particularly high risk for transfusion reactions due to the potential development of alloimmunization from frequent exposure to blood products.

The verification process should include matching the patient's identification band with the blood bank label, confirming ABO and Rh compatibility, verifying the unit number and expiration date, and ensuring the blood product appears normal without clots, discoloration, or hemolysis. The double-check system with another nurse serves as a critical safety measure to prevent administration errors.

While premedication may be used in some cases, it is not universally necessary and should not take precedence over proper identification. Monitoring urine output during transfusion is important but is not the priority before initiation. Blood should be transfused slowly (1-2 mL/kg/hr) for the first 15 minutes to monitor for reactions, as a rapid rate increases the risk of reactions.
