A client who weighs 154 pounds receives a prescription for epoetin alfa 50 units/kg subcutaneously 3 times a week. The medication is available in 2000 units/mL vial. How many mL should the nurse administer with each dose?
(Enter numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["1.8"]
- Convert the client's weight to kilograms: 154 pounds / 2.2 = 70 kg - Calculate the dose in units: 50 units/kg x 70 kg = 3500 units
- Calculate the volume in mL: 3500 units / 2000 units/mL = 1.75 mL
- Round to the nearest tenth: 1.8 mL
- The nurse should administer 1.8 mL with each dose.
