A nurse is to administer 500 mL of IV fluid over 4 hours. The IV tubing has a drop factor of 20 drops per mL. What is the flow rate in drops per minute?
Correct answer
B
Rationale
500 mL ├À 4 hours = 125 mL/h. (125 mL/h ├À 60 min) ├ù 20 gtt/mL = 41.67 gtt/min, rounded to 42 gtt/min. Other options are incorrect.
