The healthcare provider prescribes 2 L of 5% dextrose in water (D,W) IV to infuse in 24 hours. The IV administration set delivers 15 gtt/mL. How many gtt/min should the nurse regulate the infusion? (Enter numerical value only. If rounding is required, round to the nearest whole number.)
Answer and Explanation

The Correct Answer is ["21"]

Here's how to calculate the infusion rate (gtt/min) for the nurse to regulate:

1. We know:

Total volume of D5W solution: 2 L (liters)

Infusion time: 24 hours

IV administration set gtt/mL: 15 gtt/mL

2. We need to find the infusion rate in gtt/min.

Steps:

a. Convert liters to milliliters (mL) for better calculation:

1 liter = 1000 mL

Total volume (mL) = 2 L * 1000 mL/L

Total volume (mL) = 2000 mL

b. Convert infusion time from hours to minutes:

Infusion time (minutes) = Infusion time (hours) x Minutes per hour

Infusion time (minutes) = 24 hours * 60 minutes/hour

Infusion time (minutes) = 1440 minutes

c. Calculate the total volume of solution to be infused per minute:

Volume rate (mL/min) = Total volume (mL) / Infusion time (minutes)

Volume rate (mL/min) = 2000 mL / 1440 minutes

Volume rate (mL/min) = 1.389 mL/min (round to nearest hundredth)

d. Finally, calculate the infusion rate in gtt/min:

Infusion rate (gtt/min) = Volume rate (mL/min) x gtt/mL

Infusion rate (gtt/min) = 1.389 mL/min * 15 gtt/mL

Infusion rate (gtt/min) = 20.835 gtt/min (round to nearest whole number as requested)

Therefore, the nurse should regulate the infusion at approximately 21 gtt/min

Correct Answer is ["440"]

Explanation

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 filgrastim the nurse should administer:

1. Convert weight from pounds to kilograms:

Weight (kg) = Weight (lb) / 2.2

Weight (kg) = 132 lb / 2.2

Weight (kg) = 60 kg (approximately)

2. Calculate the total filgrastim dose per day:

Dose (mcg/kg) x Weight (kg) = Total dose (mcg)

5 mcg/kg x 60 kg = 300 mcg

3. Determine the concentration of filgrastim in the medication (mcg/mL):

Concentration (mcg/mL) = Total mcg / Volume (mL)

Concentration (mcg/mL) = 480 mcg / 0.8 mL

Concentration (mcg/mL) = 600 mcg/mL

4. Calculate the volume (mL) to administer for the prescribed dose (considering the concentration):

Volume to administer (mL) = Dose (mcg) / Concentration (mcg/mL)

Volume to administer (mL) = 300 mcg / 600 mcg/mL

Volume to administer (mL) = 0.5 mL (round to nearest tenth)

Therefore, the nurse should administer 0.5 mL of filgrastim subcutaneously.
