If a patient experiences a transfusion reaction during IV therapy, what should be done first?

Stopping the transfusion is the most critical initial step when a patient experiences a transfusion reaction during IV therapy. This action is crucial because continuing the transfusion can exacerbate the patient's reaction and lead to severe complications, some of which can be life-threatening. By halting the transfusion immediately, the healthcare provider minimizes the potential for further adverse effects.

Maintaining venous access is also important, but this should be done with a normal saline solution to keep the line open while preventing further infusion of the blood product. This underscores the necessity of prioritizing patient safety first by stopping the offending agent. After stopping the transfusion, other steps can be taken, such as notifying the physician and checking vital signs, but they come after ensuring that the transfusion is no longer ongoing. The timely cessation of the transfusion reaction is vital for effective management of the situation.
