The nurse teaches a new registered nurse who is preparing to administer packed red blood cells to a client. Which action by the new registered nurse requires immediate intervention?

Rationale: A. Using a 20-gauge or larger IV catheter is appropriate for packed red blood cell (PRBC) transfusions. Smaller catheters can hemolyze the red blood cells, so this action is correct and safe. B. Priming the transfusion set with normal saline is correct because other IV solutions (such as dextrose or Ringer’s lactate) can cause hemolysis of the red blood cells. This action follows standard transfusion protocols. C. Waiting 45 minutes after obtaining the PRBCs before starting the infusion is unsafe. Blood products must be started within 30 minutes of leaving the blood bank to reduce the risk of bacterial proliferation and transfusion-related infection. Delaying beyond 30 minutes increases the risk of hemolysis and infection, making this a priority safety concern requiring immediate intervention. D. Telling the patient that PRBCs may cause a serious transfusion reaction is appropriate and reflects proper patient education. Patients must be informed of potential adverse reactions, including fever, chills, hemolytic reactions, and allergic responses
