A nurse is preparing to administer filgrastim 480 mcg subcutaneous daily. Available is filgrastim injection 300 mcg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Given: Ordered dose: 480 mcg filgrastim Available concentration: 300 mcg/mL To find: Volume to administer (mL) Calculation: We need to find the volume that contains 480 mcg of filgrastim. We can achieve this by dividing the ordered dose (480 mcg) by the concentration (300 mcg/mL). Volume (mL) = Ordered dose (mcg) / Concentration (mcg/mL) Volume (mL) = 480 mcg / 300 mcg/mL Round the answer to the nearest tenth: Volume (mL) = 1.6 mL (rounded) Answer: The nurse should administer 1.6 mL of filgrastim injection per dose.
