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 ["4.8"]

Explanation

The vial is labeled as “100 mg per 4 mL.”

This means that each mL contains 25 mg of the medication (100 mg / 4 mL = 25 mg/mL).

The nurse needs to administer 120 mg of the medication.

To find out how many mL this is, we divide the dose by the concentration:

VolumeinmL = 120mg / 25mg/mL ​ = 4.8mL

If rounding is required to the nearest tenth, the nurse should administer 4.8 mL of the medication.

Correct Answer is ["0.64"]

Explanation

Here's the calculation:

Prescribed dose: 40 mg methylprednisolone

Medication vial concentration: 125 mg per 2 mL (given on the vial label)

We need to find the volume (mL) containing the prescribed dose (40 mg) of methylprednisolone.

Calculation:

Concentration adjustment: The concentration is given in mg per 2 mL. To calculate the medication needed for the 40 mg dose, we need the concentration in mg/mL.

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

Concentration (mg/mL) = 125 mg / 2 mL

Concentration (mg/mL) = 62.5 mg/mL

Volume to administer:

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

Volume to administer (mL) = 40 mg / 62.5 mg/mL

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

Therefore, the nurse should administer 0.64 mL of methylprednisolone.
