A pH reading of 6 for aspirate indicates placement in which anatomical location?

• A. Lungs
• B. Stomach
• C. Intestines
• D. Esophagus

Answer: (A)

When checking placement by aspirate pH, acidic gastric contents are expected to have a low pH (typically under about 5). A pH reading around 6 is near neutral, which is more consistent with secretions from the respiratory tract rather than the stomach. Therefore, a pH of 6 suggests the aspirate may be coming from the lungs rather than the stomach or intestines. Remember, pH testing isn’t perfect on its own, and radiographic confirmation is the definitive method to verify tube placement.
