What test should be performed to confirm tube placement of a nasoenteric feeding tube before the start of feedings?
A. An x-ray study
B. Auscultation of the abdomen
C. Assessment of stomach content pH
D. Assessment of residual stomach contents
A
An x-ray study is the most accurate confirmation method for ascertaining the exact placement of an enteral feeding tube and should always be done on initial tube insertion. Auscultation is com-pletely unreliable. Residual assessment is difficult to obtain with small-bore feeding tubes. The pH of the fluid returned is more reliable than auscultation or residual assessment but not as cer-tain as x-ray confirmation.
