بعد تركيب أنبوب أنفي معدي للتغذية، ما الطريقة المعتمدة للتأكد من مكانه قبل أول استخدام؟

After inserting an NG feeding tube, what is the accepted way to confirm placement before first use?

1. Hearing an air bolus with a stethoscope over the stomach
2. Placing the tube end in water and watching for bubbles
3. An X-ray confirming the tip is in the stomach
4. Asking the client whether he can speak normally

Answer: C) An X-ray confirming the tip is in the stomach. Radiography is the standard before first feeding or medication. Auscultation is unreliable; later checks use aspirate pH and external tube length.
