護理師準備為病人給予靜脈注射抗生素，下列哪些措施是降低用藥錯誤風險的必要程序？（選所有適合的）
A nurse is preparing to administer an intravenous antibiotic to a client. Which actions are essential to reduce the risk of medication errors? (Select all that apply.)
- AVerify the medication against the MAR using two patient identifiers✓ 正解使用兩項病人識別碼，依藥物記錄表（MAR）核對藥物。
- BScan the barcode on the patient’s identification band✓ 正解掃描病人識別手環上的條碼。
- CCheck for allergies prior to administration✓ 正解給藥前確認過敏史。
- DPrepare medications for multiple patients simultaneously to save time同時為多位病人準備藥物以節省時間。
- EPerform the three checks of medication safety✓ 正解執行藥物安全的三讀檢查。
用藥安全的核心在於「三讀五對」。護理師在給藥前必須核對醫囑（MAR），並使用兩個病人識別碼（姓名、生日或病歷號）確認身分。使用條碼給藥系統（BCMA）掃描病人手圈是現代醫院防範給藥錯誤的關鍵機制。確認過敏史能預防過敏性休克。同時配藥會增加混淆風險，絕對禁止。落實這些標準流程是降低醫療錯誤的必要手段。
Essential actions to reduce medication errors include verifying the order against the MAR using two patient identifiers, scanning the barcode on the ID band, checking for allergies, and performing the three checks of medication safety. These steps confirm the right patient receives the right drug and prevent life-threatening hypersensitivity reactions, while preparing medications for multiple patients simultaneously should be avoided to prevent confusion.
