護理師準備給藥，採取哪項措施最能預防給藥錯誤？
A nurse is preparing to administer medications to a client. Which action is the most effective way to prevent medication errors?
- APerform a double check with another nurse for high-alert drugs對高警訊藥物與其他護理師進行雙重核對
- BAsk the client to state their name and date of birth請病人自報姓名與出生日期
- CScan the client’s barcode and the medication barcode✓ 正解掃描病人與藥物的條碼
- DVerify the medication against the MAR three times三次核對藥物與給藥紀錄單（MAR）
預防給藥錯誤是病人安全的核心。條碼給藥系統（BCMA）透過電子化比對病人腕帶上的條碼與藥物條碼，能有效串聯電子病歷（EMR）與醫囑，是目前臨床公認最能有效消除人為辨識錯誤的技術性手段。其他選項雖為傳統「給藥權利（Rights of Medication Administration）」的一部分，但屬於人為核對，容易因疲勞或分心而失效。
Barcode medication administration (BCMA) is the most effective method for preventing errors because it electronically verifies the patient's identity against the medication order, reducing reliance on manual checks which are prone to human error. While double-checking high-alert drugs and verifying the MAR are important safety steps, they do not offer the same level of systematic error prevention as barcode scanning.
台灣醫院目前已大量普及條碼給藥（BCMA），但在部分基層診所或較舊的醫療系統中，仍以傳統「三讀五對」為主。美國醫療機構則將 BCMA 視為給藥安全的必要基礎設施。
