A nurse is caring for a client with a nasogastric (NG) tube. What is the most reliable method for checking tube placement?
- AMonitoring for coughing or gagging監測是否有咳嗽或作嘔反應
- BObtaining an X-ray confirmation✓ 正解取得X光確認
- CTesting the pH of the aspirated gastric contents檢測抽吸出的胃內容物的pH值
- DAuscultating for a 'whoosh' of air in the stomach聽診胃部是否有空氣吹入的「呼嘯」聲

確認鼻胃管(NG tube)位置至關重要,因誤置於氣管可能導致嚴重的吸入性肺炎或氣胸。臨床上,胸腹部 X 光攝影是確認管路位置的「金標準(Gold Standard)」,能精確定位管尖是否位於胃部。其他方法如聽診氣泡測試或抽吸胃液 pH 值,雖在臨床上常被使用,但準確度均遠低於 X 光,不應作為首次置管後的唯一確認依據。
An X-ray is the most reliable and definitive method for confirming nasogastric tube placement, serving as the gold standard to prevent complications like aspiration. Other methods, such as auscultation or pH testing, are less accurate and should not be used as the sole means of verification.
✦ 台美臨床差異
美國臨床實務對於鼻胃管置入後的 X 光確認要求非常嚴格,護理師在取得放射線報告確認位置前,絕對禁止給予任何灌食或藥物。
