mL
Explanation & Rationale
Client weight: 132 pounds Dosage: 5 mcg/kg/day Filgrastim concentration: 480 mcg/0.8 mL First, convert pounds to kilograms: 132 pounds × 0.453592 kg/lb ≈ 59.874 kg Now, calculate the dosage: Dosage = 5 mcg/kg/day × 59.874 kg ≈ 299.37 mcg ≈ 299.4 mcg Next, determine the volume needed: Concentration = 480 mcg/0.8 mL Volume = Dosage / Concentration Volume = 299.4 mcg / 480 mcg/0.8 mL Volume ≈ 0.5 mL The nurse should administer approximately 0.5 mL of filgrastim.
