A patient is prescribed a medication to be infused using a microdrip system. How many drops per mL of fluid does a microdrip set usually deliver?

A. This is not a standard IV tubing drop factor. It is too low for a microdrip set and would deliver fluid very slowly, making precise small-volume administration impractical. B. Microdrip IV sets are designed to deliver 60 drops per milliliter, allowing accurate delivery of small fluid volumes, which is essential for pediatric patients or clients requiring precise fluid control. C. A drop factor of 20 gtt/mL is typical of macrodrip tubing, which delivers larger drops for routine adult infusions and is not suitable for precise, small-volume administration. D. This is not a clinically used drop factor. No IV tubing delivers 600 drops per milliliter; it is far beyond practical and safe infusion rates.
