若藥物標籤無法辨識，護理師應採取什麼行動？

核心概念：藥物安全（Medication Safety）是護理的核心職責之一，確保給予病人的藥物是正確的，並且在正確的時間、以正確的途徑和劑量給予。藥物標籤（Label）是識別藥物的首要依據。 為何正確答案對：選項 C 指出「將藥物交回藥劑部重新標籤或更換」。這是處理藥物標籤無法辨識時最安全、最正確的做法。藥物標籤包含關鍵資訊（藥名、濃度、有效期限、批號等），若無法辨識，則無法確認藥物的正確性，繼續使用可能導致嚴重的給藥錯誤。 為何其他選項錯： D. 「猜測藥物名稱」（Guess the medication name）是極度危險的行為。即使護理師有經驗，猜測也可能出錯，導致給予錯誤的藥物或劑量，後果不堪設想。 B. 「丟棄藥物」（Discard the medication）雖然能確保安全，但可能造成藥物浪費，且病人可能因此延誤治療。在可能的情況下，應先嘗試追溯與更正。 A. 「詢問另一位護理師猜測」（Ask another nurse to guess）與選項 D 同樣危險。即使是經驗豐富的護理師，在資訊不足的情況下猜測也是不安全的。應由藥劑部負責確認與重新標籤。 臨床思路（Safety / Medication Administration）：藥物安全強調「絕不猜測」。任何對藥物識別的疑慮，都應停止操作，並尋求正確的資訊來源。將無法辨識標籤的藥物交由專業藥劑部門處理，是確保病人用藥安全的標準流程。

Core concept: Medication safety is one of the nurse's central responsibilities, ensuring that the medication given to the patient is correct and is administered at the right time, by the right route, and at the right dose. The medication label is the primary basis for identifying a drug. Why the correct answer is correct: Option C states, "Return the medication to the pharmacy for relabeling or replacement." This is the safest and most correct course of action when a medication label is illegible. The label contains critical information (drug name, concentration, expiration date, lot number, etc.); if it cannot be read, the medication cannot be verified, and continued use may result in a serious medication error. Why the other options are incorrect: A. "Guess the medication name" is extremely dangerous. Even an experienced nurse may guess incorrectly, leading to administration of the wrong drug or dose, with disastrous consequences. B. "Discard the medication" may ensure safety, but it can waste the drug and delay the patient's treatment. Whenever possible, an attempt should first be made to trace and correct the issue. C. "Ask another nurse to guess" is equally dangerous as option D. Even an experienced nurse cannot safely guess in the absence of sufficient information. Verification and relabeling should be performed by the pharmacy. Clinical reasoning (Safety / Medication Administration): Medication safety emphasizes "never guess." Any doubt about drug identification should halt the procedure, and a reliable source of information should be sought. Returning a medication with an illegible label to the professional pharmacy for handling is the standard procedure for ensuring patient medication safety.

藥物識別安全原則，包括對無法辨識標籤藥品的處理方式，在美國和台灣的臨床實務中是完全一致的。兩地都強調「Never Guess」（絕不猜測），並要求將問題藥品交由藥劑部處理。這是全球通行的藥物安全標準。此部分無顯著差異。
