A small-bore feeding tube is placed. Which technique will the nurse use to best verify tube placement?

Choice A reason: Auscultation involves listening for a "whooshing" sound after injecting air into the feeding tube. While this method is used, it is not the most reliable for confirming tube placement. Auscultation can mislead the nurse, especially if the tube is misplaced in the respiratory tract. Choice B reason: Aspiration of contents involves drawing fluid from the feeding tube to check for the presence of gastric contents. This method can help but does not guarantee the exact location of the tube. If the tube is misplaced in the lungs, the aspirate may still appear misleadingly normal. Choice C reason: pH testing involves measuring the acidity of the aspirated fluid. Gastric contents typically have a low pH, indicating proper placement. While pH testing is more reliable than auscultation, it is not infallible and can be influenced by various factors, such as medication use or the type of feeding. Choice D reason: X-ray is the gold standard for verifying the placement of a small-bore feeding tube. It provides a clear and accurate visualization of the tube's location, ensuring it is correctly positioned in the stomach or small intestine. This method eliminates the risk of misplacement and potential complications.
