Question

Infuse 1000 mL of NS. The infusion set delivers 15 gtt/mL. Give 300 mL bolus over 20 minutes and then infuse at the hourly rate of 60 mL/hr. What should the rate of infusion (in mL/hr) be set after the bolus dose?

Answer 1

rate of infusion is 900 mL/hr

Step-by-step explanation:

given data

Infuse I1 = 1000 mL

delivers = 15 gtt/mL

Infuse I2 = 300 mL

time t= 20 min

rate = 60 mL/hr

to find out

rate of infusion

solution

we know here we give 300 mL infuse in 20 min

so here for 20 min

rate of infusion is express as

rate of infusion = I2 / t

rate of infusion = 300 / 20

rate of infusion = 15 mL / min

rate of infusion = 15 × 60 = 900

so rate of infusion is 900 mL/hr
