@nursing.with.beatrice: For a newly placed NG tube, the most reliable way to definitively confirm placement before the first feeding or medication administration is X-ray confirmation. Why the other options are not definitive: * A. Inject air and auscultate over the stomach - the “whoosh test” is not considered reliable for confirming NG tube placement. * B. Check the pH of aspirate - pH testing can help assess ongoing tube position, but it does not replace radiographic confirmation of a newly inserted tube. * D. Ask whether the tube feels comfortable - patient comfort does not confirm where the tube tip is located. Once initial placement has been confirmed, ongoing checks may include assessing the external tube length and testing aspirate pH according to facility policy. Correct answer: C. Obtain an X-ray confirmation. #NursingWithBeatrice #NGTube #NasogastricTube #NCLEX #NCLEXQuestions
