High-output fistula is defined as an output exceeding how many milliliters per day?

High-output fistula is defined as an output exceeding how many milliliters per day?

• A. 250 mL/day
• B. 750 mL/day
• C. 500 mL/day
• D. 200 mL/day

Answer: (C)

High-output fistula is defined by daily drainage that is greater than 500 mL. This cutoff is used to signal more aggressive fluid and electrolyte losses, guiding more intensive management, including closer monitoring and potentially parenteral nutrition along with electrolyte replacement. So the threshold you use to label something as high-output is 500 mL per day; outputs exceeding that value are considered high-output. While very large outputs (like 750 mL/day) are also high-output, the question is asking for the defining threshold, which is 500 mL/day.
