護理師照護一位放置鼻胃管（NG tube）的病人，確認管路位置最可靠的方法為何？
A nurse is caring for a client with a nasogastric (NG) tube. What is the most reliable way to verify tube placement?
- AX-ray confirmation✓ 正解X光確認
- BAspirating gastric contents for pH testing抽吸胃內容物進行酸鹼值測試
- CListening for air rush over the stomach聽診胃部是否有氣流聲
- DChecking the external length of the tube檢查管路外部長度

放射線檢查（X-ray）是判斷鼻胃管位置最可靠的黃金標準，尤其是在首次放置或懷疑移位時。雖然測量 pH 值很有幫助，但 X-ray 視覺化的確認是防止管路誤入氣管導致吸入性肺炎的唯一絕對證明。聽氣泡聲已不再被視為可靠評估。
An abdominal X-ray is the gold standard and most reliable method for confirming correct nasogastric tube placement, especially initially or if displacement is suspected. While pH testing of aspirated contents provides supportive evidence, it is less definitive than visual confirmation via imaging. Methods such as auscultating air insufflation are considered unreliable and are no longer recommended for verification.
