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.)

Identify the given information: Dose of filgrastim: 480 mcg Concentration of filgrastim injection: 300 mcg/mL Calculate the volume of filgrastim injection to be administered: Volume = Dose (mcg) / Concentration (mcg/mL) Substitute the values: Volume = 480 mcg / 300 mcg/mL Volume = 1.6 mL
