When measuring urine output, how should you read the amount?

• A. Read the amount at eye level on a flat surface with a paper towel under it
• B. Read from above
• C. Read from below
• D. Read while holding the container

Answer: (A)

Reading urine output at eye level is essential because the liquid forms a curved surface (the meniscus), and viewing from an angle can make the level look higher or lower. To get an accurate reading, place the container on a flat, level surface and view the measurement straight on, at the level of the bottom of the meniscus. Keep the container steady, and using a clean paper towel under it helps prevent spills and keeps the surface stable. Reading from above, below, or while holding the container can tilt it or change the viewing angle, leading to an inaccurate measurement.
