Immediate cessation of transfusion is a critical first response to an acute hemolytic transfusion reaction. This type of reaction can occur when the recipient’s immune system attacks the transfused red blood cells, typically due to ABO incompatibility. When signs of an acute hemolytic reaction are observed—such as fever, chills, back pain, or dark urine—stopping the transfusion immediately is essential to prevent further hemolysis and related complications.

The other potential consequences mentioned do not address the critical nature of the response required. Delayed onset of symptoms might occur after a transfusion, but during an acute reaction, immediate action is necessary. An increased leukocyte count may occur as part of the inflammatory response, but it is not a direct consequence of the hemolysis itself nor is it an immediate concern. Symptomless transfusions are not relevant in the context of acute reactions since these reactions are characterized by obvious and often severe symptoms that necessitate immediate intervention.
