Answer: NONE OF THE ABOVE OPTIONS ARE CORRECT.

Explanation:

EPO(Erythropoietin) can be used in patients who are going to have a major surgery in which significant blood loss is expected.

By administering EPO in the month before the surgery the patient often has a 1-2 gram rise in hemoglobin (increased hematocrit level) and this decreases the chance that a blood transfusion will be needed during the surgery.
