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 for one dose: 1. Convert client weight to kilograms (kg): Weight (kg) = Weight (pounds) / 2.205 Weight (kg) = 126 pounds / 2.205 Weight (kg) = 57.14 kg (round to two decimal places for better accuracy) 2. Calculate the dose per administration based on weight and prescribed dose: Dose per administration (units) = Prescribed dose (units/kg) x Weight (kg) Dose per administration (units) = 50 units/kg x 57.14 kg Dose per administration (units) = 2857 units (round to nearest whole number) 3. Calculate the volume (mL) to administer for one dose: Volume (mL) = Dose per administration (units) / Concentration (units/mL) Concentration (units/mL) = 10,000 units/mL (given on the vial label) Volume (mL) = 2857 units / 10,000 units/mL Volume (mL) = 0.2857 mL (round to nearest hundredth as requested) Therefore, the nurse should administer approximately 0.29 mL of epoetin alfa for one dose.
