Calculation
A nurse is preparing to administer lactated Ringer's at 100 mL/hr. The drop factor of the manual IV tubing is 15 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
gtt/min
Explanation & Rationale
Volume to infuse per hour = 100 mL/hr Drop factor = 15 gtt/mL Time = 60 minutes/hr Formula: Flow rate (gtt/min) = (Volume (mL/hr) x Drop factor (gtt/mL)) / Time (min/hr) Flow rate (gtt/min) = (100 mL/hr x 15 gtt/mL) / 60 min/hr = 1500 gtt/hr / 60 min/hr = 25 gtt/min
