In the infusion setup, what is the tubing drip factor used for calculating gtt/min in this scenario?

• A. 5 gtt/mL
• B. 10 gtt/mL
• C. 15 gtt/mL
• D. 20 gtt/mL

Answer: (C)

Drip factor tells you how many drops make up 1 mL, which lets you convert a prescribed volume over time into drops per minute. In this infusion setup, the tubing delivers 15 drops per milliliter, so you use 15 gtt/mL in the formula. Gtt per minute = (volume to be infused in mL) × (drip factor in gtt/mL) ÷ (time in minutes). Because the tubing is 15 gtt/mL, multiply the volume by 15 and divide by the infusion time. If you used a different tubing factor (for example, 10 or 20), the computed gtt/min would change accordingly. Example: infusing 100 mL over 60 minutes would be 100 × 15 ÷ 60 = 25 gtt/min.
