The healthcare provider prescribes filgrastim 5 mcg/kg/day subcutaneously for a client who weighs 132 pounds and has just completed chemotherapy. The medication is available in 480 mcg/0.8 mL. How many mL should the nurse administer? (Enter numerical value only. If rounding is required, round to the nearest tenth).

Calculation: Convert the patient's weight from pounds (lb) to kilograms (kg). Patient weight (kg) = 132 lb / 2.2 lb/kg = 60 kg. Calculate the total dose in micrograms (mcg). Total dose (mcg) = Patient weight (kg) x Ordered dose (mcg/kg) = 60 kg x 5 mcg/kg = 300 mcg. Identify the available concentration. Available concentration = 480 mcg / 0.8 mL = 600 mcg/mL. Calculate the volume to administer in milliliters (mL). Volume to administer (mL) = Desired dose (mcg) / Available concentration (mcg/mL) = 300 mcg / 600 mcg/mL = 0.5 mL.
