A bleeding patient requires red cells before pretransfusion testing is complete. What is the best laboratory practice?
1Delay all blood until the antibody identification is final regardless of clinical urgency, even if the patient is hemodynamically unstable and actively bleeding, as per standard protocol for elective transfusions
2Issue an ABO-incompatible unit selected at random without any serological testing or physician consent, ignoring the patient's ABO type and relying on guesswork
3Follow the emergency-release policy, document authorization, issue appropriate uncrossmatched blood, and complete testing as soon as possible✓ 정답
4Skip patient identification because the situation is urgent and rely solely on the nurse's verbal report of blood type without any verification
해설
Emergency release balances immediate clinical need with transfusion safety. Identification, authorization, documentation, and completion of testing remain required.
