Answer to Question 1

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.

Answer to Question 2

ANS: C
Be sure that the formula is at room temperature. Cold formula causes gastric cramping and discomfort because the mouth and the esophagus do not warm the liquid. Do not use safety pins. Safety pins can become unfastened and may cause harm to the patient. 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. Gastric fluid of patient who has fasted for at least 4 hours usually has a pH of 1 to 4, especially when the patient is not receiving gastric-acid inhibitor.
