The healthcare provider prescribes epoetin alfa 50 units/kg subcutaneously (SubQ) twice daily (BID) for a client who weighs 126 pounds. The available vial is labeled, "10,000 Units/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 hundredth.)

Here's how to calculate the volume (mL) of epoetin alfa the nurse should administer: 1. Client weight conversion: Client weight: 126 pounds Medication dosage is based on weight per kilogram (kg). We need to convert the weight to kg for accurate calculation. Conversion factor: 1 kg = 2.205 lbs Client weight (kg) = 126 pounds / 2.205 lbs/kg Client weight (kg) = 57.14 kg (round to nearest hundredth) 2. Epoetin alfa dosage: Prescribed dose: 50 units/kg (given) 3. Epoetin alfa concentration: Vial label: 10,000 Units/mL 4. We need to find the volume (mL) to administer that provides the prescribed dose (50 units/kg) based on the client's weight (57.14 kg) and the medication concentration (10,000 Units/mL). Calculation: Total epoetin alfa dose (units): Dose (units/kg) x Client weight (kg) Total epoetin alfa dose (units): 50 units/kg * 57.14 kg Total epoetin alfa dose (units): 2857 units (round to nearest whole number) Volume to administer (mL): Total dose (units) / Concentration (units/mL) Volume to administer (mL): 2857 units / 10,000 Units/mL Volume to administer (mL): 0.2857 mL (round to nearest hundredth as requested) Therefore, the nurse should administer approximately 0.29 mL of epoetin alfa subcutaneously.
