The order from a provider is: Vancomycin 2 g in 500 mL of d5W IV daily to be administered over 2 hours. What is the rate on the infusion pump?
The Correct Answer is ["250"]
To calculate the rate for an infusion pump, you would use the formula: rate (mL/hr) = volume to be infused (mL) / time for infusion (hr). In this case, the volume to be infused is 500 mL and the time for infusion is 2 hours. Therefore, the infusion pump rate would be calculated as 500 mL divided by 2 hours, resulting in a rate of 250 mL/hr.

Correct Answer is ["100"]
Explanation
To calculate the IV pump rate, you'll need to use the formula: (Volume in mL) / (Time in hours) = Rate in mL/hr. For clindamycin 300 mg premixed in 50 mL to be administered over 30 minutes, you would convert the minutes into hours (which is 0.5 hours), and then divide the total volume of the IV solution by this time. So, the calculation would be 50 mL / 0.5 hours = 100 mL/hr.
Correct Answer is ["25"]
Explanation
Total Penicillin dose: 3 gm (as given in the order)
Available volume: The pharmacy provides 150 mL of NS with the Penicillin already diluted.
Infusion time: 1 hour.
Rate (mL/min) = Total volume (mL) / Total time (minutes)
1 hour = 60 minutes
Rate (mL/min) = 150 mL / 60 minutes = 2.5 mL/min
Drop factor: The drip factor is 10 gtt/mL, meaning 10 drops deliver 1 mL of solution. Rate (gtt/min): To find the rate in gtt/min, multiply the rate (mL/min) by the drip factor (gtt/mL).
Rate (gtt/min) = Rate (mL/min) x Drip factor (gtt/mL)
Rate (gtt/min) = 2.5 mL/min x 10 gtt/mL = 25 gtt/min
