護理師欲透過鼻胃管（NG tube）給藥。哪項操作正確？
A nurse is administering a dose of medication via an NG tube. Which action is appropriate?
- ACheck for placement before administration✓ 正解給藥前確認管路位置
- BMix all medications together in one syringe將所有藥物混合在同一支注射器中
- CFlush with 50 mL of water between each medication每種藥物之間用 50 mL 水沖洗
- DUse an infusion pump for all liquid meds對所有液體藥物使用輸注幫浦
鼻胃管給藥的核心在於預防誤吸（Aspiration）及確保藥物有效吸收。給藥前確認管路位置（Tube placement）是 NCLEX 的絕對優先（Priority）動作，因為管路可能移位至氣管。此外，藥物應分開給予並沖洗，以防止藥物交互作用或管路堵塞。臨床執行時需遵循『給藥安全五大原則』，確認病人身分並確保管路在胃內。
The core principles of nasogastric (NG) tube medication administration are prevention of aspiration and ensuring effective drug absorption. Verifying tube placement before administration is the absolute NCLEX priority action because the tube may be displaced into the trachea. In addition, medications should be given separately and flushed between doses to prevent drug interactions or tube occlusion. Clinical practice must follow the Five Rights of Medication Administration, verify patient identity, and ensure the tube is positioned in the stomach.
在美國臨床，確認管路位置的黃金標準是『X 光影像』，而 NCLEX 考試中，若無影像，則以 pH 值檢測作為確認依據。台灣臨床偶爾見到聽診法（氣泡法），但在美方考試中，聽診法已被視為不可靠且不推薦。
