A nurse is discussing treatment options with a client in the early stages of chronic renal failure. Which treatment modality focuses on removing waste products and excess fluid from the blood using a machine?

A) Incorrect. Severe anemia in chronic renal failure is characterized by low hemoglobin levels, not elevated levels.

B) Incorrect. Chronic renal failure can lead to decreased red blood cell production, resulting in a reduced red blood cell count.

C) Correct. Chronic renal failure often leads to decreased production of erythropoietin, a hormone that stimulates red blood cell production. This deficiency results in low hematocrit levels and severe anemia.

D) Incorrect. Chronic renal failure is not typically associated with elevated platelet counts; in fact, it can lead to platelet dysfunction and an increased risk of bleeding.

A) Correct. Fatigue and weakness are early clinical manifestations of chronic renal failure, often due to anemia and the accumulation of waste products in the blood.

B) Incorrect. Hematuria may be present in some cases of kidney dysfunction, but it is not typically an early symptom of chronic renal failure.

C) Incorrect. Shortness of breath and chest pain are more likely to be associated with fluid overload or cardiac issues, which may occur in advanced stages of chronic renal failure.

D) Incorrect. Hyperkalemia is a complication of chronic renal failure but may not be an early clinical manifestation. It is more likely to occur as kidney function declines and potassium excretion becomes impaired.
