Answer:
166.7 mL/hr
Explanation:
Using the given information, it can be determined that the pump will be infusing 250 mL of volume over 90 minutes.
By setting up a proportion and cross-multiplying, the infusion rate in mL per hour can be determined:
250 mL / 90 min = x mL / 60 min
90x = 250(60)
90x = 15000
x = 15000 ÷ 90
x = 166.7 mL
The infusion rate is 166.7 mL infused in 60 minutes. Therefore, the infusion pump should be programmed to 166.7 mL/hr.
