Calculate the IV flow rate in gtt/min for the following administrations, unless another unit of
measure is stated.
1000 mL D5LR to infuse in 8 hr. Drop factor: 20 gtt/mL.
How many gtt/min? - ANSWER Answer: 42 gtt/min
gtt/min=
20gtt/mL x 1000mL/8hr x 1hr/60min=
20gtt x 1000mL x 1hr= 20000
1mL x 8hr x 60min= 480
20000/480=
41.67 (round to whole #)
42 gtt/min
1000 mL LR to infuse in 10 hr. Drop factor: 20 gtt/mL - ANSWER Answer 33 gtt/min
gtt/min=
20 gtt/mL x 1000mL/10hr x 1hr/60min=
20gtt x 1000mL x 1 hr= 20000
1mL x 10hr x 60 min= 600
20000/600=
33.33 (round to whole #)
