What is the typical starting rate for full-strength formula when initiating enteral feeds?

• A. 10-40 mL/hour
• B. 25 mL/hour
• C. 75 mL/hour
• D. 5 mL/hour

Answer: (A)

Starting enteral feeds with a full-strength formula is done at a conservative rate to balance delivering nutrition with the gut’s ability to handle the feed. A common starting range for a continuous feed is 10 to 40 mL per hour. This modest amount lets the stomach and intestines adapt, reduces the risk of intolerance such as cramping, vomiting, or high gastric residuals, and lowers the chance of aspiration. If the patient tolerates it well over the next several hours, advance the rate in small steps—typically 10 to 20 mL per hour every 4 to 8 hours—until the prescribed goal is reached. If intolerance occurs, slow the rate or hold and reassess the plan. Starting at 75 mL/hour would be too aggressive for initiation, while starting at 5 mL/hour would unnecessarily delay meeting nutritional needs.
