Where should you measure fluid intake to ensure an accurate reading?

• A. On a bed table
• B. On a chair
• C. On a flat level surface
• D. On the floor

Answer: (C)

Measuring fluid intake accurately comes from placing the cup on a flat, level, stable surface. When the container is upright and on a level plane, you can read the measurement marks straight at eye level, which gives the true amount consumed. If the cup is on an inclined or unstable surface, or being held in a hand while reading from an odd angle, the liquid level can appear higher or lower than it really is, leading to an incorrect reading. A flat, stable surface—like a bedside table or tray—reduces spills and ensures a reliable, precise measurement.
