護理師準備經鼻胃管給藥，下列哪項護理措施對確保病人安全至關重要？
A nurse is preparing to administer a medication via a nasogastric (NG) tube. Which nursing action is essential to ensure client safety?
- ACrush all enteric-coated tablets together for easier administration將所有腸溶錠磨碎以便給藥
- BFlush the tube with 15-30 mL of sterile water before and after medication✓ 正解給藥前後用 15-30 mL 無菌水沖洗管路
- CCheck for gastric residual volume before administering each medication每次給藥前檢查胃殘留量
- DMix the medication with the client's enteral feeding formula將藥物與病人的腸內營養配方混合
鼻胃管（NG tube）給藥必須嚴格遵守無菌與藥物動力學原則。沖管是確保藥物順利進入胃部且管路不被藥物殘渣阻塞的關鍵步驟。臨床操作中，給藥前確認管路位置（Place verification）與給藥後沖管（Flush）是標準程序，能有效預防管路阻塞與藥物交互作用。正確的做法是給藥前後分別以15-30mL無菌水沖管。
Medication administration through a nasogastric (NG) tube must strictly observe aseptic technique and pharmacokinetic principles. Flushing is the key step to ensure that medication reaches the stomach and that the tube is not obstructed by drug residue. Clinically, verifying tube placement before administration and flushing afterward are standard procedures that effectively prevent occlusion and drug interactions. The correct technique is to flush the tube with 15-30 mL of sterile water before and after medication administration.
美國臨床非常強調給藥前檢查管路位置（如pH檢測或氣泡聽診確認），且嚴格禁止將藥物直接加入灌食袋中，以避免藥物與營養配方產生化學反應。
