Question: When checking Robert's red cell unit, the nurses notice that the blood groups are different, with Robert's blood group being AB RhD positive, while the blood pack is A RhD positive. The graduate nurse is hesitant about the blood group compatibility; however, Robert's nurse is fairly confident that the two different blood groups are compatible. What should the nurses do? Commence the transfusion as the more senior nurse is fairly confident the blood groups are compatible Proceed with the transfusion as the laboratory follow multiple checks before issuing blood and they would not make a mistake Return the red cell unit to the transfusion laboratory immediately as all blood groups need to be identical Contact the transfusion laboratory to confirm the compatibility. If there is any doubt the transfusion should not proceed
