Which of the following is NOT a descriptor used for fistula output characteristics?

• A. Volume
• B. Color
• C. Odor
• D. Time of day

Answer: (D)

Assessing fistula output focuses on the qualities of the effluent that guide care and protect the skin, hydration, and infection risk. Volume tells you how much is being lost, which helps manage fluids and electrolytes. Color provides clues about bile, infection, or mucous content. Odor can signal infection or contamination of the effluent. Time of day, however, doesn’t describe a property of the output itself; it’s a timing detail, not a characteristic used to gauge the patient’s condition or guide treatment. So the descriptor not used for fistula output characteristics is the timing of the output.
