When preparing to administer a blood transfusion, which of the following actions is essential for the nurse to take to ensure client safety?

Blood transfusion therapy involves the administration of blood or blood components to treat conditions such as anemia, hemorrhage, or coagulopathies. Because transfusion reactions can be severe and potentially life-threatening, strict safety protocols must be followed. These include proper patient identification, blood product verification, and timely administration to reduce the risk of bacterial growth and product degradation. Ensuring compatibility and correct patient matching is the most critical step before initiation. Rationale: A. Administering blood through a standard IV line without filters is unsafe because blood products must be infused using an appropriate blood administration set with an in-line filter. The filter helps remove microaggregates and debris that could cause complications such as microembolism. Using a standard IV line without proper equipment increases the risk of adverse transfusion reactions. B. Obtaining vital signs one hour after starting the transfusion is incorrect because baseline vital signs must be obtained before initiating the transfusion and then monitored closely after starting. Early detection of transfusion reactions depends on frequent monitoring, typically before transfusion, 15 minutes after initiation, and periodically throughout the infusion. Waiting one hour delays recognition of potentially serious reactions. C. Verifying the client's identity and the blood product with another licensed professional is essential for transfusion safety. This double-check process ensures the correct blood type, compatibility, and patient match, significantly reducing the risk of transfusion errors. Misidentification is a leading cause of transfusion-related complications, making this step critical before administration. D. Initiating the transfusion within 1 hour of obtaining the blood product from the blood bank is incorrect. Blood products should generally be started within 30 minutes of receipt to reduce the risk of bacterial growth and maintain product integrity. Delaying beyond recommended timeframes increases the risk of contamination and reduces the effectiveness and safety of the transfusion.
