Which of the following is the best method for confirming nasogastric tube placement?

  • A. Auscultating over the stomach while injecting air
  • B. Checking the pH of the aspirate
  • C. Observing the patient's response during feeding
  • D. Measuring the external length of the tube
Correct Answer: B

Rationale: Checking the pH of the aspirate is the most reliable method to confirm nasogastric tube placement as it provides direct evidence of the tube's location in the stomach. When the pH is acidic (pH < 5), it indicates that the tube is correctly placed in the stomach. Auscultating over the stomach while injecting air may not always be accurate, as the sound can be misleading due to various factors. Observing the patient's response during feeding is not a definitive method for confirming tube placement, as it can be influenced by other factors. Measuring the external length of the tube does not ensure correct placement within the GI tract and can be affected by external factors like patient anatomy.
