護理師準備經由中央靜脈導管（CVC）給藥，下列哪項安全步驟最為關鍵？
A nurse is preparing to administer medication via a central venous catheter. What is the most critical safety step?
- AScrub the hub with alcohol for 15 seconds用酒精擦拭接頭 15 秒
- BVerify the patient's identity with two identifiers✓ 正解使用兩種識別方式驗證病人身份
- CConfirm blood return from the catheter確認導管有血液回流
- DFlush the line with 10 mL saline用 10 mL 生理食鹽水沖洗管路
— Explanation · 中文詳解 —
無論進行任何侵入性治療，病人辨識（Two-identifier）皆為首要安全機制，以防給藥錯誤。雖然 scrubbing the hub（A）與回血確認（C）在技術上很重要，但在護理安全原則中，確認「對的人」永遠列在最優先的 ABC 或安全層級之首。
Regardless of which invasive treatment is performed, patient identification (using two identifiers) is the primary safety mechanism to prevent medication errors. Although scrubbing the hub (A) and confirming blood return (C) are technically important, in nursing safety principles, confirming 'the right person' always sits at the top of the ABC or safety hierarchy.
✦ 台美臨床差異
台美皆推行兩項辨識法，但在美國若未確實辨識，護理師可能面臨嚴重的執照懲戒，台灣則較重視團隊溝通文化。
