A patient with chronic kidney disease has persistent fatigue and a hemoglobin level of 8.5 g/dL. Which explanation best describes the likely cause?
Correct answer: A. Reduced production of erythropoietin by the kidneys
- A. Reduced production of erythropoietin by the kidneys
- B. Increased production of erythropoietin by the liver
- C. Excessive destruction of platelets in the spleen
- D. Increased absorption of iron from the intestine
Explanation
Diseased kidneys produce less erythropoietin, so the bone marrow receives less stimulation to make red blood cells. This causes a normocytic anemia and fatigue. Iron deficiency may also occur, but it is not the main mechanism of anemia in chronic kidney disease.
