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 ["4.7"]

Explanation

Here's how to calculate the volume (mL) of the reconstituted ampicillin solution the nurse should administer for each dose:

1. We know the following:

Prescribed dose: 140 mg ampicillin (given)

Vial information:

Contains 250 mg ampicillin powder (given)

Reconstituted with 8.3 mL sterile normal saline (given)

Yields a final concentration of 30 mg/mL (given)

2. We need to find the volume (mL) of the reconstituted solution containing the prescribed dose (140 mg) considering the final concentration (30 mg/mL).

Steps:

a. Don't consider the initial volume (8.3 mL) of sterile normal saline. The final concentration (30 mg/mL) refers to the concentration in the diluted solution after adding the saline.

b. Use the following formula:

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

c. Plug in the values:

Volume to administer (mL) = 140 mg / 30 mg/mL

Volume to administer (mL) = 4.67 mL (round to nearest tenth)

Therefore, the nurse should administer approximately 4.7 mL of the reconstituted ampicillin solution intravenously every 8 hours for the child.

Correct Answer is ["83"]

Explanation

The nurse should set the infusion pump to deliver the entire 2 liters (2000 mL) over the course of 24 hours.

Therefore, the IV pump should be set to deliver:

Rate(mL/hr) = Totalvolume(mL) / Time(hr) ​= 2000mL ​/ 24hr

After performing the calculation, we find that the rate equals 83.33 mL/hr.

So, the nurse should set the infusion pump to deliver 83 mL/hr (rounded to the nearest whole number).

This is because 83 mL of the solution contains the prescribed dose of penicillin G every hour.
