A nurse assesses a patient with renal insufficiency and a low red blood cell count. The patient asks, "Is my anemia related to my kidney problem?". Which statement would serve as the basis for the nurse's response?

Red blood cells produce erythropoietin, which increases blood flow to the kidneys.

Your anemia and kidney problem are related to inadequate vitamin D and a loss of bone density.

Erythropoietin is usually released from the kidneys and stimulates red blood cell production in the bone marrow.
