Why are erythropoiesis-stimulating agents (ESAs) prescribed for patients with chronic kidney disease?
a. To protect the kidney from further hypoxic damage during anemia episodes
b. To improve blood cell counts and reduce the need for blood transfusions
c. To prevent vein thromboembolism during periods of dehydration
d. To reduce the risk of uric acid precipitation and renal failure
B
ESAs stimulate the bone marrow to produce more red blood cells. The person with chronic kid-ney disease has chronic anemia because the damaged kidney no longer produces natural eryt-hropoietin. The use of ESAs in patients with chronic kidney disease improves red blood cell counts and reduces anemia to such an extent that blood transfusions often are no longer needed.
