Calculation
Filgrastim 5 mcg/kg/day SUBQ is prescribed for a child with cancer who weighs 88 pounds. The medication is labeled "Filgrastim 300 mcg/ml." How many mL should the nurse administer daily to this child? (Enter the numerical value only. If rounding required, round to the nearest tenth.)
mL
Explanation & Rationale
Convert the child's weight from pounds to kilograms: Weight (kg) = Weight (pounds) / 2.2 pounds/kg = 88 pounds / 2.2 pounds/kg = 40 kg Calculate the prescribed daily dose in micrograms: Daily dose (mcg) = Prescribed dose (mcg/kg/day) x Child's weight (kg) = 5 mcg/kg/day x 40 kg = 200 mcg Calculate the volume to administer in mL: Volume to administer (mL) = Desired dose (mcg) / Available concentration (mcg/mL) = 200 mcg / 300 mcg/mL ≈ 0.666... mL Round to the nearest tenth: Rounded volume = 0.7 mL
