After a diagnosis of chronic kidney disease (CKD), the client was started on epoetin. Which finding indicates that the medication has been effective?

Choice A reason: An increase in serum hematocrit indicates that epoetin has been effective. Epoetin, also known as erythropoietin, is a medication used to stimulate the production of red blood cells. In patients with chronic kidney disease, the kidneys may not produce enough natural erythropoietin, leading to anemia. By administering epoetin, the goal is to increase red blood cell production, which is reflected in higher hematocrit levels (the proportion of red blood cells in the blood).Choice B reason: An increase in serum calcium is not related to the effectiveness of epoetin. Serum calcium levels are regulated by different mechanisms, including parathyroid hormone and vitamin D, and are not directly influenced by epoetin administration.Choice C reason: A decrease in serum creatinine levels would indicate improved kidney function, but this is not the expected outcome of epoetin therapy. Epoetin specifically targets red blood cell production and does not have a direct impact on kidney function or creatinine levels.Choice D reason: A decrease in blood pressure is also not an expected indicator of epoetin effectiveness. While managing blood pressure is important in chronic kidney disease, epoetin's primary role is to address anemia by stimulating red blood cell production. Blood pressure regulation involves other medications and interventions.
