I&O stands for which term?

• A. Inflow and Outflow
• B. Inlet and Output
• C. Inlet and Outflow
• D. Intake and Output

Answer: (D)

Intake and output measures the fluids a patient takes in and loses, a key way to monitor fluid balance. In practice, intake includes all fluids a patient consumes by mouth, IV fluids, and tube feedings. Output covers urine, vomit, diarrhea, wound drainage, and other measurable losses. By comparing intake to output over a period, clinicians assess hydration status and kidney function, guiding treatment decisions such as adjusting fluids or addressing fluid overload or dehydration. The other pairings aren’t the standard term used in medical care—terms like inlet/outlet or inflow/outflow are more common in engineering or piping contexts, so intake and output is the conventional medical terminology.
