I&O stands for which nursing measurement?

• A. Intake and Output
• B. Input and Output
• C. Infection and Onset
• D. Intubation and Obstruction

Answer: (A)

I&O stands for intake and output, the nursing measurement used to track a patient’s fluid balance. Intake includes every fluid the patient consumes or receives that adds to body fluids—oral drinks, soups, IV fluids, tube feeds, and any fluids given for medications. Output covers the measurable fluid losses—urine, vomit, liquid stool, drainage from wounds, and other liquid expulsions. Insensible losses like sweat or breathing are not usually counted in I&O because they’re not easily measured. Tracking these together helps identify dehydration or fluid overload, guides treatment decisions (such as adjusting IV fluids or diuretics), and supports monitoring of kidney function and overall hydration status. The data are typically kept in milliliters and reviewed over time to spot trends.
