Question

1000 mL of D5W is ordered to be infused over 5 hours. The drop factor is 10 gtt/mL. How many gtt/min should be given to infuse the 1000 mL over 5 hours?

Answer 1

flow rate of to infuse the 1000 mL over 5 hours is 33.33 gtt/min

Explanation:

Given data

volume = 1000 mL

time = 5 hours

drop factor = 10 gtt/min

to find out

flow rate of to infuse the 1000 mL over 5 hours

Solution

we know flow rate formula i.e.

flow rate = ( volume × drop factor ) / time .................1

here time will be in min so time = 5 hours = 5 × 60 = 300 min

put volume, drop factor and time value in equation 1 and we get flow rate

flow rate = ( volume × drop factor ) / time

flow rate = ( 1000 × 10 ) / 300

flow rate = 33.33 gtt/min

flow rate of to infuse the 1000 mL over 5 hours is 33.33 gtt/min
