A nurse assesses a client with renal insufficiency and a low red blood cell count. The client asks, "Is my anemia related to the renal insufficiency?" How should the nurse respond?
a. "Red blood cells produce erythropoietin, which increases blood flow to the kidneys."
b. "Your anemia and renal insufficiency are related to inadequate vitamin D and a loss of bone density."
c. "Erythropoietin is usually released from the kidneys and stimulates red blood cell production in the bone marrow."
d. "Kidney insufficiency inhibits active transportation of red blood cells throughout the blood."
ANS: C
Erythropoietin is produced in the kidney and is released in response to decreased oxygen tension in the renal blood supply. Erythropoietin stimulates red blood cell production in the bone marrow. Anemia and renal insufficiency are not manifestations of vitamin D deficiency. The kidneys do not play a role in the transportation of red blood cells or any other cells in the blood.
