What is the immediate nursing action when a transfusion reaction is suspected?

• A. Stop transfusion immediately
• B. Return blood to lab
• C. Notify physician
• D. Monitor vitals

Answer: (A)

The first and most important action is to stop the transfusion immediately. Halting the transfusion at once prevents further exposure to the donor blood, which can rapidly worsen a transfusion reaction. After stopping, keep the IV line open with normal saline using new tubing, and promptly notify the physician and the blood bank per protocol. Send the blood product and any required samples to the lab for investigation, and monitor the patient’s vital signs and clinical status as treatment is initiated.
