The healthcare provider prescribes 2 L of 5% dextrose in water (DW) 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 ["100"]

Explanation

The nurse should set the infusion pump to deliver the entire 150 mL over the course of 90 minutes.

First, convert the time from minutes to hours because the rate is required in mL/hr.

90 minutes is 1.5 hours (since 1 hour = 60 minutes).

Therefore, the IV pump should be set to deliver:

Rate(mL/hr)=Time(hr)Totalvolume(mL)​=1.5hr150mL​

After performing the calculation, we find that the rate equals 100 mL/hr.

So, the nurse should set the infusion pump to deliver 100 mL/hr. This is rounded to the nearest whole number as per the instructions.

Correct Answer is ["100"]

Explanation

The medication is to be administered over 30 minutes,

so if we want to find out the rate in mL/hour,

we need to double the total volume because there are 60 minutes in an hour.

Therefore, the infusion pump should be set to deliver

50mL/30minutes ​× 60minutes / hour = 100mL/hour

So, the answer is 100. The nurse should program the infusion pump to deliver 100 mL/hour
