The nurse is teaching a child experiencing chronic renal failure about his diet. The nurse should discuss which of the following dietary recommendations?

Calcium intake should be restricted.

The child should eat three large meals per day and limit snacks between meals.

Potassium intake should be limited.

Sodium intake should be increased.

Answer and Explanation

The Correct Answer is C

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 D

Explanation

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.

A. "The father has the trait, but the mother doesn’t." B. "The mother has the trait, but the father doesn’t." C. "Both the mother and the father have the sickle cell trait." D. "The mother has sickle cell disease, but the father doesn't have the disease or the trait."

Correct Answer is C

Explanation

Choice A reason: This option is incorrect because sickle cell disease is an inherited condition, and one parent having the trait is not sufficient for a child to have the disease.
Choice B reason: This option is also incorrect for the same reason as choice A; both parents must carry the trait for the child to have a chance of inheriting the disease.
Choice C reason: This is the correct choice. Sickle cell disease is inherited when both parents carry the sickle cell trait, giving their child a 25% chance of having the disease.
Choice D reason: This option is incorrect because if only one parent has sickle cell disease and the other has neither the disease nor the trait, the child cannot have sickle cell disease.
