The Healthcare provider prescribes epoetin alfa 75 units/kg SUBQ for a client who weighs 80 kg. The available vial is labeled, epoetin alfa 10,000 units/mL. Based on the client's weight, how many milliliters should the nurse administer to the client for a safe single dose?
step 1: identify the ordered dose, weight and available dose
Ordered dose = 75 units/ kg
Weight of the patient = 80 kg
Available dose= 10,000 units/ ml
Step 2: calculate the units to be given according to the weight of the person
Multiply the order dose by the weight of the patient
= 75 units × 80 kg
= 6000 units
Heance 6000 units have to be administer for 80 kg patient. ( this is the ordered dose for 80 kg patient)
Step 3 : calculate desired dose
Use the formula
= (ordered dose/ available dose) x volume
=(6000/10,000) × 1ml
= 0.6 x 1 ml
= 0.6 ml
Hence, 0.6 ml of medication should be administered for the single dose.
