Calculation
A nurse is preparing to administer dextrose 5% in water 350 mL IV to infuse over 3 hr. The drop factor of the manual IV tubing is 10 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 = 350 mL Drop factor = 10 gtt/mL Time to infuse = 3 hours = 3 x 60 minutes = 180 minutes Formula: Flow rate (gtt/min) = (Volume (mL) x Drop factor (gtt/mL)) / Time (min) Flow rate (gtt/min) = (350 mL x 10 gtt/mL) / 180 min = 3500 gtt / 180 min = 19.44 gtt/min Round to the nearest whole number = 19 gtt/min
