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.)

Determine the desired dosage: The nurse needs to administer 480 mcg of filgrastim. Determine the volume per dose: The filgrastim injection contains 300 mcg per 1 mL. The nurse needs to administer 480 mcg per dose. To find the volume per dose: 300 mcg / 1 mL = 480 mcg / x mL Cross-multiplying gives us: 300x = 480 Dividing both sides by 300, we get: x = 1.6 mL
