What is the correct sequence for a blood transfusion procedure?

• A. Baseline vitals → Verify order → Start transfusion → Reassess vitals
• B. Reassess vitals → Verify order → Start transfusion → Baseline vitals
• C. Verify order → Baseline vitals → Start transfusion → Reassess vitals
• D. Verify order → Start transfusion → Baseline vitals → Reassess vitals

Answer: (C)

In transfusion safety, you want to confirm the exact order and patient, establish a health reference before you begin, then monitor closely during and after the transfusion. The best sequence is to verify the order first, then record baseline vitals, start the transfusion, and finally reassess vitals as the infusion progresses.

Verifying the order first ensures you’re acting on the correct request and patient data. Taking baseline vitals before starting gives you a reference point to detect any early signs of a transfusion reaction, such as fever, chills, or changes in blood pressure, heart rate, or breathing. Starting the transfusion after establishing those baselines allows you to compare post-infusion vitals to the starting point. Reassessing vitals during and after the transfusion completes the safety check, helping catch any adverse reactions promptly.

Why the other sequences are less safe: taking baseline vitals before verifying the order or before confirming the patient and product would miss an essential safety check, reassessing before the order is verified can lead to acting on incorrect instructions, and starting the transfusion before obtaining baseline vitals eliminates the critical reference point needed to spot early reactions.
