A small-bore feeding tube is placed. Which technique will the nurse use to best verify tube placement?
a. X-ray
b. pH testing
c. Auscultation
d. Aspiration of contents
ANS: A
At present, the most reliable method for verification of placement of small-bore feeding tubes is x-ray examination. Aspiration of contents and pH testing are not infallible. The nurse would need a more precise indicator to help differentiate the source of tube feeding aspirate. Auscultation is no longer considered a reliable method for verification of tube placement because a tube inadvertently placed in the lungs, pharynx, or esophagus transmits sound similar to that of air entering the stomach.
