When administering Lasix ordered at 50 mg IV push with a concentration of 20 mg/mL, how many milliliters should be given?

To determine how many milliliters of Lasix (furosemide) should be administered, you start by knowing the ordered dose and the concentration of the medication. The order specifies 50 mg of Lasix, and the concentration is 20 mg/mL.

To find the volume to administer, you use the formula:

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

Substituting the known values into this formula gives:

Volume (mL) = 50 mg / 20 mg/mL

When you perform the calculation:

Volume (mL) = 50 / 20 = 2.5 mL

This indicates that to achieve the required dose of 50 mg with a concentration of 20 mg/mL, you should administer 2.5 mL. Thus, the correct response reflects this calculated volume, confirming that administering 2.5 mL will deliver the ordered 50 mg of Lasix.
