Which action is performed as part of essential pretransfusion nursing actions, with the best practice being the two-nurse check?

• A. Verify patient identity
• B. Crossmatch compatibility
• C. Perform two-nurse check
• D. Record vital signs

Answer: (C)

Safety hinges on a robust two-person verification before starting a transfusion. The two-nurse check provides independent verification that the right patient is getting the right blood product and that the product matches the order and crossmatch. In practice, two qualified nurses confirm the patient’s identity using two identifiers, verify the unit’s labeling (including blood type, unit number, and expiration date), and ensure the crossmatch results and physician order align with what is being administered. This redundancy catches errors such as mislabeling, patient misidentification, or wrong-unit administration before any blood is transfused, making it the most effective safeguard in essential pretransfusion nursing actions. Other steps like confirming patient identity or checking vital signs are important parts of the overall transfusion process, but the two-nurse check specifically provides the critical independent verification that prevents administering the wrong blood.
