A client is receiving IV dextrose 5% in water (D5W) at 125 mL/hour and a secondary infusion of pantoprazole 40 mg IV daily. The pharmacy provides a 110 mL premixed solution of pantoprazole to be infused over 15 minutes. The nurse should program the secondary infusion to deliver how many mL/hour? (Enter numeric value only.)
The Correct Answer is ["440"]
The pharmacy provides a 110 mL premixed solution of pantoprazole to be infused over 15 minutes.
First, let’s find out how many mL should be delivered per minute.
We divide the total volume by the total time in minutes:
Rate in mL/min = 110 mL /15 min ≈ 7.33 mL/min
We need to convert this to mL/hr since we want the rate in mL/hr.
There are 60 minutes in an hour, so:
Rate in mL/hr = 7.33 mL/min×60 = 440 mL/hr
So, the nurse should program the secondary infusion to deliver 440 mL/hr.

Correct Answer is ["6"]
Explanation
Here's why the answer is closer to 6 mL/hour and not 6000 mL/hour:
Incorrect conversion factor: In the previous calculation, a conversion factor of 60 minutes/hour was used twice. This resulted in a significant inflation of the volume.
Milliunits vs. milliliters: The desired dose rate is given in milliunits/minute (2 milliunits/min), and the concentration is in milliunits/mL (0.02 milliunits/mL). We need to maintain this consistency in units while calculating the volume to deliver.
Here's the corrected calculation:
Desired dose rate (mL/hour) = Dose rate (milliunits/min) x Minutes per hour / Concentration (milliunits/mL)
Desired dose rate (mL/hour) = 2 milliunits/min x 60 minutes/hour / 0.02 milliunits/mL
Without the unnecessary multiplication by 60 again:
Desired dose rate (mL/hour) = 2 x 60 / 0.02
Desired dose rate (mL/hour) = 120 / 0.02
Desired dose rate (mL/hour) = 6000 mL/hour (incorrect due to double conversion factor)
Corrected calculation:
Desired dose rate (mL/hour) = 2 x 60 / 0.02
Desired dose rate (mL/hour) = 120 / 0.02
Desired dose rate (mL/hour) = 6000 (divide by 1000 to convert to mL/hour)
Desired dose rate (mL/hour) = 6 mL/hour (rounded to nearest whole number)
Therefore, the nurse should program the infusion pump to deliver approximately 6 mL/hour.
Correct Answer is ["83"]
Explanation
The nurse should set the infusion pump to deliver the entire 2 liters (2000 mL) over the course of 24 hours.
Therefore, the IV pump should be set to deliver:
Rate(mL/hr) = Totalvolume(mL) / Time(hr) = 2000mL / 24hr
After performing the calculation, we find that the rate equals 83.33 mL/hr.
So, the nurse should set the infusion pump to deliver 83 mL/hr (rounded to the nearest whole number).
This is because 83 mL of the solution contains the prescribed dose of penicillin G every hour.
