Explanation
Flowrate(gtt/min)=Time(min)Volume(mL)×Dropfactor(gtt/mL)
Given:
Volume = 250 mL (vancomycin in 250 mL of D5W)
Time = 2 hours = 120 minutes
Dropfactor=15gtt/mLtubingdropfactor
Step 1: Calculate the flow rate:
rate=250 mL120 min×15 gtt/mL
Flowrate=2.0833×15=31.25gtt/min
Step 2: Round to the nearest whole number:
Answer: 31 drops per minute
