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 ["17"]
Explanation
Let’s calculate the solution step by step:
Calculate the Total Drops in the IV Bag:
The total number of drops in the IV bag can be calculated using the formula:
Totaldrops = VolumeinmL × DropspermL
Substituting the given values:
Totaldrops = 150mL × 10drops/mL = 1500drops
Calculate the Rate in Drops/Minute:
The rate in drops per minute can be calculated using the formula:
Rateindrops/minute = Totaldrops / Timeinminutes
Substituting the given values:
Rateindrops/minute = 1500drops/90minutes ≈ 16.67drops/minute
Since the problem asks for the rate to be rounded to the nearest whole number if necessary, the final rate is 17 drops/minute.
Correct Answer is ["0.64"]
Explanation
Here's the calculation:
Prescribed dose: 40 mg methylprednisolone
Medication vial concentration: 125 mg per 2 mL (given on the vial label)
We need to find the volume (mL) containing the prescribed dose (40 mg) of methylprednisolone.
Calculation:
Concentration adjustment: The concentration is given in mg per 2 mL. To calculate the medication needed for the 40 mg dose, we need the concentration in mg/mL.
Concentration (mg/mL) = Total mg / Volume (mL)
Concentration (mg/mL) = 125 mg / 2 mL
Concentration (mg/mL) = 62.5 mg/mL
Volume to administer:
Volume to administer (mL) = Dose (mg) / Concentration (mg/mL)
Volume to administer (mL) = 40 mg / 62.5 mg/mL
Volume to administer (mL) = 0.64 mL (round to nearest hundredth)
Therefore, the nurse should administer 0.64 mL of methylprednisolone.
