Question

A nurse sets an intravenous

fluid drip rate at 1000 mL
every 8 hr. How much fluid would the patient receive in
3 hr? Step by step (applications of rational equations)

Answer 1

375 mL

Explanation:

Let x = Amount of fluid patient receives in 3 hours

Fluid drip rate: 1000 mL --------- 8hr

x --------- 3 hr

Cross multiplication is applied:

(x).(8 hr) = (1000 mL).(3hr)

x = [(1000mL).(3 hr)]/ (8 hr)

x = 375 mL
