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 ["0.64"]

Explanation

Here's how to calculate the volume of methylprednisolone the nurse should administer:

1. We know:

Dose to administer: 40 mg (given)

Concentration of the medication: 125 mg per 2 mL (given from the vial label)

2. We need to find:

Volume of medication to administer (mL)

Calculation:

We can set up a proportion to find the volume needed for the desired dose:

Desired dose (mg) / Volume to administer (mL) = Concentration (mg/mL)

Rearrange the formula to solve for the volume:

Volume to administer (mL) = Desired dose (mg) / Concentration (mg/mL)

Plug in the values:

Volume to administer (mL) = 40 mg / (125 mg/2 mL)

Important note: We can divide the concentration by 2 mL because we only need the medication concentration, not the total volume in the vial (which is 2 mL).

Volume to administer (mL) = 40 mg / 62.5 mg/mL (round the concentration to nearest tenth for easier calculation)

Volume to administer (mL) = 0.64 mL (round to nearest hundredth)

Therefore, the nurse should administer 0.64 mL of methylprednisolone.

Correct Answer is ["1.3"]

Explanation

here's how to calculate the volume (mL) of filgrastim the nurse should administer:

Client weight conversion:

Client weight: 176 pounds

Since medication dosage is based on weight per kilogram (kg), we need to convert the weight to kg for accurate calculation.

Conversion factor: 1 kg = 2.205 lbs

Client weight (kg) = 176 pounds / 2.205 lbs/kg

Client weight (kg) = 80 kg (round to nearest whole number)

Filgrastim dose per kg:

Dose per kg = 5 mcg/kg (given)

Filgrastim concentration:

The medication vial is labeled 300 mcg/mL. This indicates there are 300 mcg of filgrastim in every 1 mL of solution.

We need to find the volume (mL) containing the prescribed dose (based on weight) of filgrastim (5 mcg/kg) considering the concentration (300 mcg/mL) in the vial.

Total filgrastim dose (mcg): Dose (mcg/kg) x Client weight (kg)

Total filgrastim dose (mcg): 5 mcg/kg * 80 kg

Total filgrastim dose (mcg): 400 mcg

Volume to administer (mL): Total dose (mcg) / Concentration (mcg/mL)

Volume to administer (mL): 400 mcg / 300 mcg/mL

Volume to administer (mL) = 1.33 mL (round to nearest tenth)

Therefore, the nurse should administer approximately 1.3 mL of filgrastim subcutaneously.
