A nurse is caring for a client experiencing fatigue secondary to anemia from chronic kidney disease (CKD). How should the nurse respond when the client asks about the cause of the anemia symptoms they are experiencing?

"The increased metabolic waste products in your body depress the bone marrow and cause anemia."

"You have a genetic tendency for the development of anemia."

"You are not eating enough iron-rich foods, which is causing anemia."

"There is a decreased production by the kidneys of the hormone erythropoietin, which is the cause of your anemia."
