HESI RN Dosage Calculation Proctored Exam
Calculation
The healthcare provider prescribes filgrastim 5 mcg/kg subcutaneous (SubQ) for a client who weighs 176 pounds. The available vial is labeled, "Filgrastim 300 mcg/mL." Based on the client's weight, how many milliliters should the nurse administer? (Enter numerical value only. If rounding is required, round to the nearest tenth.)
mL
Explanation & Rationale
Step 1: Convert weight from pounds to kilograms. 176 pounds ÷ 2.2 = 80 kg Step 2: Calculate the total dosage in mcg. 5 mcg/kg × 80 kg = 400 mcg Step 3: Identify the concentration. 300 mcg/mL Step 4: Calculate the volume to administer. 400 ÷ 300 = 1.3333 Rounded to the nearest tenth = 1.3 mL
