A nurse aspirates the client’s stomach contents and checks the contents’ pH before tube feeding. The nurse confirms the tube placement is correct when the pH level reads:

pH 2.7
pH 4.5
pH 7.0
pH 8.0

Explanation

Answer: A - The gastric fluid, composed of digestive fluids, has a pH of 1.0-2.0. The pH level in the duodenum or jejunum is 4.5 - 5.0. Gastric fluids are acidic to help break down the structure of proteins. A pH or 7.0 or 8.0 is too alkalinized.
