A nurse assesses a client with renal insufficiency and a low red blood cell count. The client asks, "is my anemia related to my kidney problem?" How would the nurse respond?

Rationale: A. The kidneys do not transport red blood cells; the circulatory system does. This option confuses renal function with circulatory processes. B. Red blood cells do not produce erythropoietin; rather, the kidneys produce erythropoietin to stimulate red blood cell formation in the bone marrow. C. While vitamin D metabolism and bone density are affected by kidney disease, these are not the primary cause of anemia in renal insufficiency. D. The kidneys produce erythropoietin, a hormone that stimulates red blood cell production in the bone marrow. In renal insufficiency, reduced erythropoietin secretion leads to anemia due to decreased red blood cell formation.
