When adjusting a continuous tube feed, by how much and how often is the rate advanced?

• A. By 10-25 ml/hour every 4-24 hours.
• B. By 60 ml every 8-12 hours.
• C. By 100 ml every hour.
• D. Not adjusted once started.

Answer: (A)

Gradual advancement with gentle, small increases and regular reassessment is the safe, effective way to pace a continuous tube feed. Start at a modest rate and increase by about 10 to 25 mL per hour, checking tolerance and residue every several hours (typically around 4 to 6 hours, but it can be extended up to 24 hours if the patient is stable). This approach helps meet caloric goals without overwhelming the GI tract or raising the risk of aspiration. Pushing the rate too fast (for example, large hourly increases or frequent rapid changes) can cause vomiting, abdominal distention, diarrhea, or high residuals, while not adjusting at all can leave the patient underfed. So the recommended pattern is steady, incremental increases at monitored intervals.
