Why is calibration of a medicine dropper important?

• A. Increases drop size
• B. Maintains sterilization
• C. Measures liquids accurately
• D. Reduces cost

Answer: (C)

Calibrating a medicine dropper ensures the volume you dispense matches the marked measurement. A dropper can vary in how much liquid each drop contains due to factors like drop formation, liquid viscosity, temperature, and manufacturing tolerances. By calibrating, you align the scale with the actual delivered volume, so every administration delivers the intended dose. This accuracy is crucial for safety and effectiveness, especially with potent or pediatric medicines where small deviations can have big consequences. It also helps keep dosing consistent between different users and over time. Sterility and cost considerations are separate issues: calibration doesn’t inherently maintain sterility, and its main purpose isn’t to reduce costs.
