護理師準備給藥前，下列哪項措施最能有效預防給藥錯誤？
A nurse is preparing to administer a medication to a client. Which action is the most effective way to prevent medication errors?
- AVerifying the client's name and date of birth確認病人姓名與出生日期
- BUsing a barcode scanning system✓ 正解使用條碼掃描系統
- CAsking the client if they have any allergies詢問病人是否有過敏史
- DChecking the medication label twice檢查藥物標籤兩次
給藥安全的核心目標是減少人為失誤（Human Error）。現代臨床實證強調運用技術輔助系統來進行「封閉迴路給藥」（Closed-loop medication administration），透過條碼給藥系統（Barcode Medication Administration, BCMA）能即時比對病人腕帶、藥物標籤與電子醫囑，確保五大給藥原則（Five Rights）的落實。這是目前公認最有效預防給藥錯誤的方法，因為它不僅依賴護理師的警覺性，更加入了系統端的硬性驗證。
Using a barcode scanning system is the most effective method to prevent medication errors because it integrates patient identification with medication orders to verify the five rights of medication administration. While verifying identifiers and checking labels are important, automated scanning provides a critical technological safeguard against human error. Allergy checks are vital but do not prevent the administration of the wrong drug.
美國臨床高度依賴 BCMA 與電子病歷（EMR）整合。台灣雖已逐步推廣條碼給藥，但在部分基層或小型醫療院所，仍較多依賴人工核對與雙人簽核，美國護理師在執業時需習慣高度依賴系統警示。
