Which daily fistula output would indicate PN according to the rule?

Explanation:
High-output fistulas cause substantial losses of fluids, electrolytes, and nutrients. The rule uses a threshold of about 500 mL per day; when fistula output exceeds this, oral or enteral intake often cannot meet energy and protein needs, so parenteral nutrition is indicated to prevent malnutrition and support healing. 520 mL/day surpasses the threshold, making PN indicated. The other values are below 500 mL/day and would not meet the rule’s criterion for PN.
