If you need to infuse 1200 mL over 6 hours with a 20 gtt/mL set, what is gtt/min?

If you need to infuse 1200 mL over 6 hours with a 20 gtt/mL set, what is gtt/min?

• A. 132 gtt/min
• B. 33.3 gtt/min
• C. 125 gtt/min
• D. 66.7 gtt/min

Answer: (D)

To find gtt/min, convert the total time to minutes and apply the drop factor to the mL per minute. 6 hours equals 360 minutes, so the infusion rate is 1200 mL / 360 min = 3.333... mL per minute. With a drop factor of 20 gtt per mL, multiply: 3.333... mL/min × 20 gtt/mL = 66.666... gtt/min. Rounded, that’s 66.7 gtt/min.
