護理師準備執行靜脈抗生素給藥。防止藥物錯誤最重要步驟為何？
A nurse is preparing to administer IV antibiotics. What is the most important step to prevent medication errors?
- AEnsure the medication is mixed properly確保藥物正確混合
- BCheck the client's identification using two identifiers✓ 正解使用兩種識別方式核对病人身份
- CExplain the drug to the client向病人說明藥物
- DCheck the expiration date檢查有效日期
藥物給藥錯誤（Medication error）是病人安全的最大威脅之一。護理師在給藥前，必須嚴格執行「三讀五對」，其中確認病人身分（Two patient identifiers）是防止給藥錯誤的第一道也是最關鍵的防線。無論護理師對病人多麼熟悉，都必須要求病人核對姓名與出生日期（或病歷號），以確保藥物給予正確的對象。
Patient identification is the primary safety measure to prevent medication errors and ensure the right drug is given to the right person. Nurses must strictly verify the client's identity using at least two unique identifiers, such as name and date of birth, before administration. This step is critical regardless of how familiar the nurse is with the client, as it serves as the first line of defense against adverse events.
美國醫院對身分核對的要求極為嚴格，通常使用條碼掃描系統（Barcode Medication Administration, BCMA），台灣近年也逐漸導入，但人工核對依然是核心。
