A client with multiple sclerosis (MS) is receiving interferon beta-1b 0.1875 mg subcutaneously every other day. The nurse reconstitutes the vial by slowly injecting 2 mL of diluent into the interferon vial for a reconstituted solution of 0.25 mg/1 mL. How many mL should the nurse administer?

(Enter numeric value only. If rounding is required, round to the nearest hundredth.)

Answer and Explanation

The Correct Answer is ["0.75"]

To determine the correct dosage, you'll need to use the concentration of the reconstituted solution to find out how many milliliters contain the prescribed dose of 0.1875 mg.

Since the solution has a concentration of 0.25 mg per 1 mL, you would divide the prescribed dose by the concentration to find the volume to administer: 0.1875 mg / 0.25 mg/mL = 0.75 mL.
