The nurse is assessing a patient’s arteriovenous (AV) fistula. Which finding provides evidence of its normal function?
Pulselessness.
Ecchymotic area.
Redness.
Enlarged vein.
The Correct Answer is D
Choice A reason: Pulselessness is not a sign of normal AV fistula function; a palpable pulse should be present.
Choice B reason: An ecchymotic area suggests bruising and is not indicative of normal function.
Choice C reason: Redness may indicate inflammation or infection, not normal function.
Choice D reason: This is the correct choice. An enlarged vein is typical for an AV fistula and indicates good blood flow through the fistula.

Explanation
Choice A reason: Restricting calcium intake is not typically recommended for children with chronic renal failure as they may already be at risk for bone disease due to altered calcium metabolism.
Choice B reason: Eating three large meals per day and limiting snacks is not specific dietary advice for chronic renal failure; nutritional needs should be tailored to the individual.
Choice C reason: This is the correct choice. In chronic renal failure, the kidneys may not be able to remove excess potassium, leading to hyperkalemia, which can be dangerous.
Choice D reason: Increasing sodium intake is not generally recommended for chronic renal failure as it can contribute to hypertension and fluid retention.
Correct Answer is A
Explanation
