- Draw back a small amount of gastric fluid and test the pH

When a patient has an orogastric or nasogastric tube in place, it is essential that the nurse check for proper placement of the tube to ensure that the tip is in the stomach and has not migrated to another area. The nurse should verify placement before administering formula or medications through the tube. The only acceptable method to confirm proper placement is to aspirate a small amount of gastric contents and to check the pH.
