護理師在給藥時，哪種行為最能有效預防給藥錯誤？
A nurse is preparing to administer medication. Which action represents the most effective way to prevent medication errors?
- AIdentifying the client using two unique identifiers使用兩個獨特識別碼來確認客戶身分
- BVerifying the dosage with another nurse before administration給藥前與另一位護理師核對劑量
- CScanning the client's barcode and the medication barcode✓ 正解掃描客戶的條碼和藥物條碼
- DChecking the medication label against the MAR three times將藥物標籤與護理記錄單核對三次
預防給藥錯誤的核心在於建立層層防護網（Safety Net）。條碼給藥系統（Barcode Medication Administration, BCMA）利用數位科技即時比對病人手圈、藥物標籤與給藥紀錄（MAR），是目前臨床證實能最有效降低人為辨識錯誤的工具。護理師雖應遵循給藥原則，但自動化系統能提供最後一道電子防線，將給藥錯誤率降至最低。
The cornerstone of preventing medication errors is establishing layered safety nets. Barcode medication administration (BCMA) uses digital technology to perform real-time matching of the patient's wristband, the medication label, and the medication administration record (MAR), and is currently the tool with the strongest clinical evidence for reducing human identification errors. Although the nurse should still follow the principles of medication administration, the automated system provides a final electronic safeguard that minimizes the rate of medication errors.
美國醫院全面推行電子化給藥系統（BCMA），幾乎所有給藥流程皆強制要求掃描。台灣雖多數醫學中心亦採用，但部分基層醫療單位仍高度依賴人工核對。赴美後請務必習慣完全依賴系統掃描，不可跳過此步驟。
