A nurse is reviewing laboratory findings for four clients. Which of the following clients has manifestations of acute kidney injury?
Hemoglobin 16 g/dL
BUN 15 mg/dL
Serum potassium 4.5 mEq/L
Serum creatinine 6 mg/dL
The Correct Answer is D
Choice A reason: A hemoglobin level of 16 g/dL is within the normal range and does not indicate acute kidney injury.
Choice B reason: A BUN level of 15 mg/dL is also within the normal range and does not suggest acute kidney injury.
Choice C reason: A serum potassium level of 4.5 mEq/L is within the normal range and is not indicative of acute kidney injury.
Choice D reason: A serum creatinine level of 6 mg/dL is significantly elevated and indicates impaired kidney function, which is a hallmark of acute kidney injury.

Correct Answer is B
Explanation
Choice A reason: Taking 3,000 mg of vitamin C daily is not recommended as it may increase the risk of calcium oxalate stones due to possible conversion of vitamin C to oxalate.
Choice B reason: Drinking 3 L of fluid every day is advised to prevent kidney stones by diluting the urine and reducing the concentration of stone-forming substances.
Choice C reason: Eating 12 oz of animal protein daily is excessive and can increase the risk of kidney stones due to higher excretion of calcium and oxalate.
Choice D reason: Restricting calcium intake to one serving per day is not recommended as a normal calcium intake is necessary to bind oxalate in the gut and reduce oxalate absorption.
Correct Answer is B
Explanation
Choice A reason: While kidney infections can cause swelling, they typically do not lead to a significant increase in abdominal girth unless associated with severe obstruction or advanced kidney disease.
Choice B reason: In PKD, the kidneys can become significantly enlarged due to the growth of numerous cysts, which
can indeed lead to an increase in abdominal girth.
Choice C reason: While stones can cause blockage and swelling, they would not typically result in a generalized increase in abdominal girth unless there is an associated infection or severe obstruction.
Choice D reason: Inflammation can lead to fluid retention, but in the context of PKD, it is the cysts' growth that primarily contributes to increased kidney size and abdominal girth.
