The practical nurse (PN) is administering a subcutaneous injection of epoetin to a client with chronic kidney disease (CKD). This medication is being administered to treat which manifestation of chronic kidney disease (CKD)?

A. Anemia: Epoetin is a synthetic form of erythropoietin, which stimulates red blood cell production. In CKD, the kidneys produce insufficient erythropoietin, leading to anemia. Administering epoetin addresses this common complication. B. Edema: Edema in CKD results from fluid retention due to impaired kidney function. Epoetin does not treat fluid overload; diuretics and fluid management are used for edema. C. Hypertension: CKD-related hypertension is managed with antihypertensive medications. Epoetin may actually increase blood pressure as a side effect but does not treat hypertension. D. Anuria: Anuria, or absence of urine output, reflects severe kidney dysfunction. Epoetin does not restore urine production; renal replacement therapy may be needed for anuria.
