A client is to receive furosemide 60 mg every 12 hours. The drug 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"]

The client is to receive furosemide 60 mg every 12 hours.

The drug is available in a concentration of 10 mg/mL, so the nurse should administer 6 mL of medication (60 mg / 10 mg/mL).

The nurse plans to administer the dosage over 20 minutes, so the infusion rate should be 18 mL/hour (6 mL / (20 minutes / 60 minutes/hour)).

Correct Answer is ["6"]

Explanation

To calculate the infusion rate in mL/hour, we can use the following formula:

Infusion rate (mL/hour) = Dose (mg/minute) x 60 / Concentration (mg/mL) In this case, the dose is 2 mg/minute and the concentration is:

200 mg/40 mL = 5 mg/mL

We can calculate the infusion rate as follows:

2 mg/minute x 60 / 5 mg/mL = 24 mL/hour

However, the total volume of the solution is 200 mL. Therefore, we need to adjust the infusion rate to ensure that the medication is infused over the correct time period. If we divide the total volume by the infusion time, we can calculate the infusion rate required to deliver the medication over that time period:

200 mL / (120 minutes) = 100 mL/hour

So we need to adjust our initial calculation to ensure that we are infusing at a rate of 100 mL/hour. We can do this by using a proportion:

2 mg/minute x 60 / 5 mg/mL = X mL/hour x 1 Solving for X gives us:

X = (2 x 60 x 1) / 5 = 24 mL/hour

So we should program the infusion pump to deliver 6 mL/hour.

Correct Answer is ["167"]

Explanation

The client with pneumonia is receiving a secondary infusion of azithromycin 500 mg in 250 mL of normal saline (NS) to be infused in 90 minutes.

To calculate the infusion rate in mL/hour, we need to divide the total volume of the infusion (250 mL) by the infusion time in hours (90 minutes / 60 minutes/hour = 1.5 hours).

The nurse should program the infusion pump to deliver 167 mL/hour (250 mL / 1.5 hours).
