IV infusion time - practice problem 2
An IV pump is running 50 mL of 0.9% normal saline at 60 mL/hr.
How long will the infusion take (hours)?
Answer: 0.83 hr
Step-by-step solution
1. Divide the volume by the rate
50 mL ÷ ( 60 mL ÷ 1 hr )
2. Cancel mL and solve for hours
= 50 ÷ 60 hr
= 0.83 hr
3. Convert the decimal hours to hours and minutes
0.83 hr = 50 min
= 50 min
