Calculation
The healthcare provider prescribes interferon beta-1b 0.1875 mg every other day for a client with multiple sclerosis. The nurse reconstitutes the single-use vial of powder labeled, "0.3 mg with 1.2 mL of sterile water." How many mL should the nurse administer to the client? (Enter the numerical value only. If rounding is required, round to the nearest hundredth.)
mL
Explanation & Rationale
Desired dose = 0.1875 mg Determine the concentration of the reconstituted solution: Concentration = Total amount of drug / Volume of diluent = 0.3 mg / 1.2 mL = 0.25 mg/mL 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
