A nurse is assessing a client with chronic renal failure. Which clinical manifestation should the nurse recognize as a common early symptom of kidney dysfunction?

A. Incorrect. Hyperthyroidism is not a known risk factor for chronic renal failure. However, uncontrolled thyroid disease may contribute to cardiovascular issues that can impact kidney health.

B. Incorrect. Peptic ulcer disease is not a risk factor for chronic renal failure.

C. Incorrect. Chronic obstructive pulmonary disease (COPD. is not directly associated with an increased risk of chronic renal failure. However, chronic illnesses can place additional stress on the kidneys over time.

D. Correct. Hypertension, or high blood pressure, is a significant risk factor for chronic renal failure. Long-term uncontrolled hypertension can damage the blood vessels in the kidneys, leading to chronic kidney disease.

A. Incorrect. Peripheral edema and weight gain are more commonly associated with fluid retention in later stages of chronic renal failure when the kidneys are unable to effectively remove excess fluids from the body.

B. Incorrect. Frothy urine and increased urination may indicate proteinuria, a condition where excessive protein is excreted in the urine. While proteinuria can be a symptom of kidney dysfunction, it is not an early symptom.

C. Incorrect. Hypertension and headache can be associated with chronic renal failure, but they are not specific to early stages of kidney dysfunction.

D. Correct. Fatigue and decreased appetite are early clinical manifestations of kidney dysfunction in chronic renal failure. The kidneys play a vital role in filtering waste products and toxins from the blood, and when kidney function is compromised, it can lead to a buildup of waste products in the body, causing fatigue and decreased appetite.
