What is the acceptable difference between the measured urinary output and the observer's measurement when emptying a urinary drainage bag?

• A. 10 cc
• B. 25 cc
• C. 50 cc
• D. 100 cc

Answer: (B)

When measuring urinary output, a small amount of variation between your measurement and the observer’s is expected due to things like reading the bag at different angles, slight clock timing differences, or how the bag is positioned. The acceptable difference is 25 milliliters, meaning your recorded output may be up to 25 mL higher or lower than the observer’s measurement and still be considered accurate. This tolerance helps reflect real-world measurement challenges while keeping documentation reliable. If the difference were larger than 25 mL, you would need to recheck the measurement and adjust accordingly. The other options are either too strict or too lenient compared to this standard tolerance.
