An oncology client is receiving an erythropoietin stimulating agent, epoetin alfa for severe anemia. The client reports severe bone pain (arthralgia). Knowing the basic pathophysiologic principles, how should the nurse explain the bone pain to this client? Bleeding is stimulating the rapid proliferation of replacement cells by the blood-forming cells in the bone marrow. The bone cells are not receiving enough oxgen; therefore, some of the cells are dying. Bleeding is causing vasoconstriction to all body tissues, which results in death of some tissues, such as is occurring within the bone. This is an adverse reaction to epoetin alfa.
