Calculation
A client with multiple sclerosis (MS) is receiving interferon beta-1b 0.1875 mg SUBQ every other day. The nurse reconstitutes the vial by slowly injecting "1.2 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.)
mL.
Explanation & Rationale
Identify the concentration of the reconstituted solution: Concentration = 0.25 mg / 1 mL = 0.25 mg/mL Identify the prescribed dose: = 0.1875 mg Calculate the volume to administer: Volume to administer (mL) = Desired dose (mg) / Concentration (mg/mL) = 0.1875 mg / 0.25 mg/mL = 0.75 mL Rounding to the nearest hundredth, the nurse should administer 0.75 mL.
