護理師準備給藥，採取下列何項措施最能確保給藥安全？
A nurse is preparing to administer medication to a client. Which action best ensures patient safety during the medication administration process?
- AAsk the client to state their name and date of birth請病人自報姓名和出生日期
- BCheck the medication label against the MAR three times三次核對藥物標籤與藥物醫囑單（MAR）
- CVerify the client's name and room number before administering給藥前核對病人姓名與床號
- DUse the medication barcode scanning system✓ 正解使用藥物條碼掃描系統
確保給藥安全的核心原則是「五個正確」（Rights of Medication Administration）。條碼給藥系統（Barcode Medication Administration, BCMA）透過掃描病人腕帶與藥物標籤，能即時與電子醫囑（MAR）比對，是目前公認降低人為疏失（如給錯藥、給錯病人）最有效的科技輔助手段。相比傳統的人工口頭核對，BCMA 提供了封閉迴路的驗證機制，能大幅降低因溝通不良或辨識錯誤導致的用藥安全事件。
Safe medication administration centers on the 'Rights of Medication Administration.' Barcode Medication Administration (BCMA) scans the patient wristband and drug label, instantly cross-checking the electronic MAR—it is the most effective technology for reducing human errors (wrong drug, wrong patient). Compared with verbal verification alone, BCMA provides a closed-loop verification mechanism that greatly reduces medication-safety events from miscommunication or misidentification.
美國醫院全面導入 BCMA 已是常態，即便掃描系統運作，護理師仍需口頭詢問病人姓名與出生日期作為最後一道安全防線，兩者並非互斥。
