A client is receiving IV DSW at 125 mL per 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 per hour? (Enter numeric value only.)
The Correct Answer is ["440"]
While the primary infusion rate (dextrose 5% in water) and the total volume of pantoprazole solution are provided, the pantoprazole infusion doesn't directly affect the rate of the primary DSW infusion.
Here's the breakdown:
Primary Infusion:
Dextrose 5% in water (DSW) at 125 mL/hour (given) - This rate remains constant throughout the secondary infusion.
Secondary Infusion:
Pantoprazole 40 mg total dose (given)
Premixed solution volume: 110 mL (given)
Infusion duration: 15 minutes (given) = 0.25 hours (convert minutes to hours)
The nurse programs the secondary infusion pump to deliver the 110 mL pantoprazole solution over 0.25 hours, independent of the primary DSW infusion.
Therefore, the nurse should program the secondary infusion pump to deliver a rate of:
Delivery rate (mL/hour) = Total volume (mL) / Infusion time (hours)
Delivery rate (mL/hour) = 110 mL / 0.25 hours
Delivery rate (mL/hour) = 440 mL/hour (This is the rate for the pantoprazole solution only)
In conclusion:
The primary DSW infusion rate remains at 125 mL/hour.
The secondary pantoprazole infusion rate is 440 mL/hour, but it delivers the total dose (110 mL) over the 15-minute timeframe.

Correct Answer is ["0.64"]
Explanation
Here's how to calculate the volume of methylprednisolone the nurse should administer:
1. We know:
Dose to administer: 40 mg (given)
Concentration of the medication: 125 mg per 2 mL (given from the vial label)
2. We need to find:
Volume of medication to administer (mL)
Calculation:
We can set up a proportion to find the volume needed for the desired dose:
Desired dose (mg) / Volume to administer (mL) = Concentration (mg/mL)
Rearrange the formula to solve for the volume:
Volume to administer (mL) = Desired dose (mg) / Concentration (mg/mL)
Plug in the values:
Volume to administer (mL) = 40 mg / (125 mg/2 mL)
Important note: We can divide the concentration by 2 mL because we only need the medication concentration, not the total volume in the vial (which is 2 mL).
Volume to administer (mL) = 40 mg / 62.5 mg/mL (round the concentration to nearest tenth for easier calculation)
Volume to administer (mL) = 0.64 mL (round to nearest hundredth)
Therefore, the nurse should administer 0.64 mL of methylprednisolone.
Correct Answer is ["0.5"]
Explanation
You can calculate the volume of heparin to administer using the following formula:
Volume (mL) = Dose (units) / Concentration (units/mL)
Here's what we know:
Dose: 5,000 units heparin (given)
Concentration: 10,000 units/mL (from the vial label)
Calculation:
Volume (mL) = 5,000 units / 10,000 units/mL
Volume (mL) = 0.5 mL
Therefore, the nurse should administer 0.5 mL of heparin.
