UO is commonly used to denote which measure?

• A. Urine output
• B. Oxygen uptake
• C. Usage oxygen
• D. Urine opacity

Answer: (A)

UO denotes urine output, the amount of urine a patient produces over a period of time. It is usually measured in milliliters per hour (mL/hr) and is a key indicator of kidney function and fluid balance. Tracking UO helps healthcare providers assess hydration status, detect kidney problems, guide fluid management, and evaluate responses to treatments. Oxygen uptake is a different measurement (often called VO2 or O2 consumption) and has nothing to do with urine output. “Usage oxygen” isn’t a standard medical term, and “urine opacity” describes appearance rather than volume.
