A client is receiving IV dextrose 5% in water (DSW) 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.)

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

Here's how to calculate the volume (mL) of epinephrine the nurse should administer:

1. Convert the client's weight from pounds to kilograms:

Weight (kg) = Weight (lb) / 2.2

Weight (kg) = 110 lb / 2.2

Weight (kg) = 50 kg (approximately)

2. Calculate the total epinephrine dose based on weight and prescribed dosage:

Dose (mg) = Dose (mg/kg) x Weight (kg)

Dose (mg) = 0.01 mg/kg x 50 kg

Dose (mg) = 0.5 mg

3. Determine the volume (mL) to administer considering the medication concentration:

Concentration (mg/mL) = 1 mg/mL (given from the medication label)

Volume (mL) = Dose (mg) / Concentration (mg/mL)

Volume (mL) = 0.5 mg / 1 mg/mL

Volume (mL) = 0.5 mL (already rounded to the nearest tenth)

Therefore, the nurse should administer 0.5 mL of epinephrine intramuscularly.
