護理師準備為成人病人進行肌肉注射，哪項措施最能確保安全？
A nurse is preparing to administer an intramuscular injection to an adult client. Which action is most appropriate to ensure safety?
- AAspirate before injecting all medications在所有藥物注射前進行抽吸
- BRecap the needle after use to prevent sticks使用後重新蓋上針帽以防針刺傷害
- CUse the Z-track technique for all IM injections對所有肌肉注射使用Z字軌跡技術
- DCheck the client's identity using two identifiers✓ 正解使用兩種識別方式確認客戶身份
給藥安全（Medication Safety）是護理照護的核心。預防給藥錯誤的最基礎步驟是正確辨識病人身份。根據全國病人安全目標（National Patient Safety Goals, NPSG），護理師在給藥前必須使用兩個病人識別符（如姓名與出生日期），且嚴禁使用病房號碼作為識別方式，因為病人可能會更換床位。
Medication safety is central to nursing care. The most fundamental step in preventing medication errors is correctly identifying the client. According to the National Patient Safety Goals (NPSG), the nurse must use two patient identifiers (such as name and date of birth) before administering medication, and room numbers must never be used as identifiers because clients may change rooms.
在美國，護理師必須在給藥前掃描病人的識別腕帶（Barcode Medication Administration, BCMA），這是最常見的「兩個識別符」確認方式。台灣目前許多醫院也已導入此系統，但仍需注意核對原則。
