IV infusion time — practice problem 4
An IV pump is running 100 mL of D5W at 50 mL/hr.
How long will the infusion take (hours)?
Answer: 2 hr
Step-by-step solution
1. Divide the volume by the rate
100 mL ÷ ( 50 mL ÷ 1 hr )
2. Cancel mL and solve for hours
= 100 ÷ 50 hr
= 2 hr
3. Convert the decimal hours to hours and minutes
2 hr = 2 hr
= 2 hr
