Which of the following indicates correct tube placement in a patient receiving an H2 blocker or PPI?

The indication of correct tube placement in a patient receiving an H2 blocker or proton pump inhibitor (PPI) is associated with a clear golden color small bowel aspirate. The presence of clear golden fluid suggests that the tube has passed through the stomach and into the small intestine, where bile is typically found, especially after fasting. This aligns with the intestinal aspiration color typical of a well-positioned feeding tube.

In contrast, bright red blood found in the tube is a concerning sign, as it indicates possible bleeding, which necessitates immediate medical attention and does not reflect proper tube placement. Cloudy gastric aspirate can be common when assessing tubes in the stomach but does not specifically indicate correct placement into the small bowel. Green bile in the aspirate, while indicative of the aspirate being from the duodenum or distal small bowel, does not rule out a gastric source and might not indicate that the tube is properly positioned for administration of H2 blockers or PPIs, which require gastric or upper intestinal access for effective absorption and action. Therefore, the clear golden color of small bowel aspirate is the best indicator of appropriate tube placement in this context.
