What is the recommended rate and interval for advancing a full-strength formula toward the goal rate when initiating enteral nutrition?

• A. Increase by 5-10 mL/hr every 24 hours
• B. Increase by 10-20 mL/hr every 8-12 hours
• C. Increase by 30-40 mL/hr every 6 hours
• D. Maintain same rate until goal is reached

Answer: (B)

Progressing enteral nutrition safely relies on small, regular increments to reach the prescribed goal while actively monitoring tolerance. Increasing the rate by 10-20 mL/hr every 8-12 hours provides a balance between moving toward the goal efficiently and allowing time to observe for signs of feeding intolerance, such as vomiting, abdominal distension, or high gastric residuals. This pace helps you reach the goal within roughly 24-48 hours without overwhelming the gastrointestinal tract. If intolerance occurs, you pause or slow the increases and reassess.

Slower increases (5-10 mL/hr every 24 hours) would prolong underfeeding and delay meeting caloric goals. Large jumps (30-40 mL/hr every 6 hours) increase the risk of intolerance and aspiration. Maintaining the same rate until the goal is reached neglects the need to titrate to tolerance and would likely leave the patient underfed.
