Final answer:
To calculate the IV pump setting, divide the total volume of 250 mL of vancomycin by the infusion time of 2 hours (120 minutes), which equals a flow rate of 125 mL/h.
Step-by-step explanation:
The question involves calculating the flow rate in milliliters per hour (mL/h) for administering a prescribed dosage of vancomycin via an intravenous (IV) pump.
Steps to Calculate the IV Flow Rate
- Determine the total volume to be infused: 250 mL of vancomycin.
- Determine the total time for infusion: 120 minutes.
- Calculate the flow rate in mL/h: Since there are 60 minutes in an hour, 120 minutes is equivalent to 2 hours. Divide the total volume by the number of hours to get the flow rate in mL/h.
- Perform the division: 250 mL ÷ 2 hours = 125 mL/h.
Therefore, the IV pump should be set to 125 mL/h to infuse vancomycin 1250 mg in 250 mL over 120 minutes.
