A client is to receive furosemide 60 mg IV every 12 hours. The medication is available in a concentration of 10 mg/mL, and based on the manufacturer's recommendations, the nurse plans to administer the dosage over 20 minutes. The nurse should set the infusion pump to deliver how many mL/hour? (Enter numeric value only.)

Answer and Explanation

The Correct Answer is ["18"]

Here's how to calculate the infusion rate (mL/hour) for the nurse to administer furosemide 60 mg IV every 12 hours:

1. Furosemide dose per administration:

Dose = 60 mg (given)

2. Dosage frequency (conversion from hours to minutes):

Frequency (minutes) = 12 hours/dose * 60 minutes/hour

Frequency (minutes) = 720 minutes/dose

3. Medication concentration:

Concentration = 10 mg/mL (given)

4. Infusion duration:

Duration = 20 minutes (given)

5. We need to find the total volume (mL) of the medication to be delivered and then convert that volume to a rate per hour (mL/hour).

Steps:

a. Calculate the volume to be infused (mL):

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

Volume (mL) = 60 mg / 10 mg/mL

Volume (mL) = 6 mL

b. Convert infusion duration from minutes to hours:

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

Infusion time (hours) = 20 minutes / 60 minutes/hour

Infusion time (hours) = 1/3 hour

c. Calculate the infusion rate (mL/hour):

Infusion rate (mL/hour) = Volume (mL) / Infusion time (hours)

Infusion rate (mL/hour) = 6 mL / (1/3 hour)

Infusion rate (mL/hour) = 18 mL/hour

Therefore, the nurse should set the infusion pump to deliver approximately 18 mL/hour.

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.

Correct Answer is ["1.5"]

Explanation

First, we need to convert the prescribed dose from mg to mcg because the available medication is labeled in mcg.

1 mg is equal to 1,000 mcg. So, 0.075 mg is equal to 75 mcg.

Given:

The prescription is for 75 mcg of levothyroxine.

The available medication is 50 mcg/tablet.

We can set up the proportion as follows:

75mcg/ xtablet = 50mcg/1tablet

Solving for x gives us the number of tablets that the nurse should administer.

Cross-multiplying and solving for x:

X = 75mcg×1tablet/50mcg

After performing the calculation, we find that x equals 1.5 tablets.

So, the nurse should administer 1.5 tablets of the medication. This is rounded to the nearest tenth as per the instructions.
