A patient 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 0.9 mL. To find the answer, we can use the following steps:
- Convert the patient's weight from pounds to kilograms by dividing by 2.2
- Multiply the weight in kilograms by the dosage in units/kg
- Divide the dose in units by the concentration in units/mL
- Round the result to the nearest tenth
Using these steps, we get:
- (weight in kg) = (154) / (2.2) = 70 kg
- (dose in units) = (50) x (70) = 3500 units
- (volume in mL) = (3500) / (2000) = 1.75 mL
- (rounded volume in mL) = 1.8 mL
Therefore, the nurse should administer 1.8 mL of epoetin alfa from the vial to the patient.
