護理師準備給藥，在給藥前確認病人身分最可靠的方法為何？

核心概念：病人安全目標中的病人識別（Patient Identification）。 為何正確答案對：美國醫療機構聯合委員會（The Joint Commission）的病人安全目標（Patient Safety Goals）明確規定，在提供照護或治療前，必須至少使用兩種病人識別方式。讓病人「親自說出」其姓名和出生日期，是驗證病人身分的兩種獨立方式（姓名+出生日期），同時也確認病人具有溝通能力，是現行最可靠且廣泛採用的標準方法。 為何其他選項錯： A. 僅稱呼病人的名字（Call the client by name）僅是一種識別方式，且病人可能不知道被叫名字的人是自己，尤其是在多人病室或病人聽力不佳時。這不符合標準的雙重識別要求。 B. 核對病房號碼和床鋪標籤（Check the room number and bed label）僅是環境識別，而非病人本身的識別。病房號或床位可能因病人轉床、臨時調度而有誤，且病人本人可能不在該床位上，或有同名同姓者住同一病房。 C. 核對門口的病歷夾（Verify the name on the door chart）與核對床鋪標籤類似，屬於環境識別，不直接與病人本人連結，有潛在的誤判風險。 臨床思路/安全優先：病人身分確認是預防醫療疏失（Medical Errors）的第一道關卡，特別是給藥時。若給錯病人，後果可能非常嚴重。因此，標準化的雙重識別步驟是病人安全的基石。

Core concept: Patient identification as part of the National Patient Safety Goals. Why the correct answer is correct: The Joint Commission's Patient Safety Goals explicitly require the use of at least two patient identifiers before providing care or treatment. Having the client personally state their name and date of birth provides two independent means of verifying identity (name + date of birth) while also confirming that the client is able to communicate; this is currently the most reliable and widely adopted standard method. Why the other options are incorrect: A. Simply calling the client by name is only one form of identification, and the client may not recognize that they are being addressed, especially in a multi-occupant room or when hearing is impaired. This does not meet the standard two-identifier requirement. C. Checking the room number and bed label is environmental identification rather than identification of the client themselves. Room or bed numbers may be inaccurate due to transfers or temporary reassignment, the client may not be in the assigned bed, and patients with the same name could share a room. D. Verifying the name on the door chart, like checking the bed label, is environmental identification not directly linked to the client themselves, and carries a potential risk of misidentification. Clinical reasoning/safety priority: Patient identification is the first defense against medical errors, especially during medication administration. Administering medication to the wrong patient can have severe consequences. Standardized two-identifier verification is therefore the cornerstone of patient safety.
