- ACheck the client's identification using two identifiers✓ 正解使用兩項識別資料核对病人身份
- BVerify medication against the MAR✓ 正解依用藥記錄單(MAR)核對藥物
- CAsk the client's family to identify the client請病人家屬協助確認病人身份
- DPerform the three checks of medication administration✓ 正解執行給藥三讀五對程序
- EScan the client's barcode on their wristband✓ 正解掃描病人手腕帶上的條碼
藥物安全是護理師執業的核心，必須嚴格執行給藥安全規範。這包括：一、使用兩項識別碼（Two patient identifiers）確認病人身分；二、核對醫囑（MAR）；三、執行三讀五對（Three checks）；四、使用條碼掃描（Barcode verification）。這些步驟能有效減少藥物給錯的可能性。家屬僅在病人無法表達時作為輔助，不可作為唯一的確認來源。
Medication safety is a core component of nursing practice and requires strict adherence to safe administration guidelines. This includes: (1) using two patient identifiers to verify identity; (2) verifying the order against the medication administration record (MAR); (3) performing the three checks of medication administration; and (4) using barcode verification. These steps effectively reduce the likelihood of medication errors. Family members should serve only as a supplementary source when the client is unable to communicate, and should not be used as the sole means of identification.
