Order Entry & ProcessingQuestion 91 of 100
1000 mL is to infuse over 10 hours using an administration set calibrated at 15 gtt/mL. What is the drip rate in gtt/min?
a.10 gtt/min
b.15 gtt/min
c.17 gtt/min
d.25 gtt/min
Explanation
1000 mL / 10 hr = 100 mL/hr, and 100 mL/hr / 60 min = 1.67 mL/min. Multiplying by the drop factor: 1.67 mL/min x 15 gtt/mL = 25 gtt/min. Answering 17 gtt/min comes from using a 10 gtt/mL set instead of the 15 gtt/mL set that was specified.
