If a transfusion reaction is suspected, what is the initial management step?

• A. Slow the transfusion and continue
• B. Stop the transfusion and notify the provider
• C. Take vitals and continue transfusion
• D. Switch to a different blood product immediately

Answer: (B)

When a transfusion reaction is suspected, the immediate priority is to stop the transfusion. Halting the infusion prevents further exposure to the donor blood, which could worsen the reaction or lead to life-threatening complications. After stopping, notify the clinician or transfusion service right away to obtain urgent orders and initiate evaluation.

Keep the IV line open with normal saline to maintain access and to flush if needed, but do not continue or resume the transfusion. Do not discard the blood bag or tubing yet; label them as a suspected transfusion reaction and send them to the blood bank for investigation. Assess the patient’s vital signs and symptoms, and follow provider instructions for further management, which may include supportive care such as fluids, oxygen, or medications. Collect required specimens and document all actions and findings.

This approach prioritizes patient safety, enables timely investigation to determine the cause, and prevents further harm from ongoing exposure.
