Correct Answer is ["83"]
Explanation
Total volume to infuse: 500 mL
Total time for infusion: 60 minutes
Drop factor of the tubing: 10 gtt/mL
To find the drops per minute, we can use the following formula:
Drops/minute=Totaltime(minutes)Totalvolume(mL)×Dropfactor(gtt/mL)
Plugging in the values:
Drops/minute=60minutes500mL×10gtt/mL
Drops/minute=60minutes5000gtt
Drops/minute=83.333...gtt/minute
Rounding to the nearest whole number, the nurse should set the manual IV infusion to deliver 83 gtt/min.
