Question

You have an infusion of furosemide 50 mg in 50 mL sodium chloride slashing 0.9%. Your patient is to receive a dose of 25 mcg/min. What is the resultant rate in mL/hr?

Answer 1

To calculate the resultant rate of the infusion in mL/hr, we need to follow these steps:

Step 1: Convert the dose from mcg/min to mg/hr. Step 2: Use the concentration of furosemide to determine the infusion rate in mL/hr.

Step 1: Convert the dose from mcg/min to mg/hr. 1 mg = 1000 mcg

25 mcg/min * (1 mg / 1000 mcg) = 0.025 mg/min

Step 2: Use the concentration of furosemide to determine the infusion rate in mL/hr. The concentration of furosemide in the solution is 50 mg in 50 mL.

To deliver 0.025 mg/min, we need to find out the corresponding mL/min and then convert it to mL/hr.

0.025 mg/min * (1 mL / 50 mg) = 0.0005 mL/min

Now, let's convert mL/min to mL/hr:

0.0005 mL/min * 60 min/hr = 0.03 mL/hr

So, the resultant rate of the infusion is 0.03 mL/hr.
