Question

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?

Answer #1

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.
