A client with chronic kidney disease reports to the nurse of feeling increasingly tired. The client receives injections for epoetin alfa three times a week. Which laboratory value should the nurse review?

A. Serum electrolytes are important to monitor in chronic kidney disease but do not directly relate to the effects of epoetin alfa. B. Platelet count is not typically affected by epoetin alfa and does not directly address the client’s symptoms of tiredness. C. Complete blood count (CBC) is crucial to monitor, especially hemoglobin and hematocrit levels, as epoetin alfa is used to treat anemia in chronic kidney disease, which can cause fatigue. D. Liver enzymes are not directly related to the effects of epoetin alfa and the symptoms described.
