    The healthcare provider prescribes filgrastim 5 mcg/kg/day subcutaneously (SubQ) 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).

    mL

    Explanation & Rationale

    Step 1: Convert the client's weight from pounds to kilograms. 132 pounds ÷ 2.2 = 60 kilograms Step 2: Calculate the total dose in mcg based on the client's weight. 5 mcg/kg × 60 kg = 300 mcg Step 3: Determine how many mL of medication to administer based on the available concentration. (300 mcg) ÷ (480 mcg/0.8 mL) = (300 ÷ 480) × 0.8 (300 ÷ 480) = 0.625 0.625 × 0.8 = 0.5 mL Result: The nurse should administer 0.5 mL of the medication.
