The client diagnosed with thalassemia, a hereditary anemia, is to receive a transfusion of packed RBCs. The cross-match reveals the presence of antibodies that cannot be cross-matched. Which precaution should the nurse implement when initiating the transfusion? 1. Start the transfusion at 10–15 mL per hour for 15–30 minutes. 2. Re–crossmatch the blood until the antibodies are identified. 3. Have the client sign a permit to receive uncrossmatched blood. 4. Have the unlicensed nursing assistant stay with the client.
