The physician gives orders to infuse 1000 mL 0.9% NS at 200 mL/h for dehydration. Tubing drop factor is 10 gtt/mL. Calculate the flow rate in drops per minute.
The Correct Answer is ["33"]
\( Flow rate (gtt/min)=60mL/hour×drop factor (gtt/mL)\)
Given:
Rate = 200 mL/hour
Drop factor = 10 gtt/mL
\(Flow rate=(200×10)/60=2000/60=33.3 gtt/min\)

Correct Answer is ["31"]
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
