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.)
Answer and Explanation

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 ["0.5"]

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.

Correct Answer is ["18"]

Explanation

Here's how to calculate the volume (mL/hour) the nurse should program the infusion pump to deliver heparin:

1. We know:

Heparin dose rate: 1,400 units/hour (given by healthcare provider)

Heparin concentration in the IV bag: 20,000 units per 250 mL (given on the label)

2. We need to find:

Volume delivery rate (mL/hour)

3. Calculation:

To find the volume rate, we can divide the heparin dose rate (units/hour) by the heparin concentration (units/mL)

Volume rate (mL/hour) = Heparin dose rate (units/hour) / Heparin concentration (units/mL)

Plug in the values:

Volume rate (mL/hour) = 1,400 units/hour / (20,000 units / 250 mL)

Important note: We can rearrange the fraction with the concentration term because we are dividing by units/mL, which is equivalent to multiplying by mL/units. So, effectively, we are multiplying by the reciprocal of the concentration.

Volume rate (mL/hour) = 1,400 units/hour x (250 mL / 20,000 units)

Volume rate (mL/hour) = 17.5 mL/hour (round to nearest whole number)

Therefore, the nurse should program the infusion pump to deliver 18 mL/hour.
