Which action helps remove air when measuring liquid meds?

• A. Tapping the syringe to remove air bubbles
• B. Warming the liquid before measurement
• C. Shaking the syringe to mix contents
• D. Reading from the bottom of the meniscus

Answer: (A)

Removing air bubbles is essential for an accurate syringe measurement. Tiny air pockets take up space that isn’t medication, so if they remain, the dose shown by the syringe won’t reflect the true liquid amount. Tapping the syringe helps gather those small bubbles so you can push them out, leaving only the liquid at the measurement line. The other actions don’t remove air: warming the liquid doesn’t eliminate bubbles and can alter the liquid’s properties, shaking the syringe can introduce more air, and reading from the bottom of a meniscus is about where to read the liquid level, not about eliminating air.
