Which parameter is used to determine PN indication in fistula patients?

• A. Fistula location
• B. Fistula output per day
• C. Patient age
• D. Presence of edema

Answer: (B)

Daily fistula output directly informs PN indication because the losses through the fistula determine how much energy, protein, and electrolytes the patient must replace. When output is high, the body loses substantial nutrients and fluids, making parenteral nutrition essential to maintain nutrition and hydration while the GI tract is bypassed or healing. If the output is low, many patients can meet needs with oral or enteral intake and may not require PN. Fistula location mainly affects healing and surgical considerations, while age and edema reflect overall status but do not by themselves decide PN needs.
