A patient with chronic kidney disease exhibits increasing fatigue and declining hemoglobin levels despite stable iron stores. Which mechanism explains this patient's developing anemia?

💡 Explanation

The patient is developing anemia because damaged kidneys produce less erythropoietin, a hormone vital for stimulating red blood cell production in bone marrow; therefore, erythropoiesis decreases, rather than the other options which concern red cell destruction or iron absorption.
