A nurse is monitoring a client who has acute kidney injury (AKI). Which of the following laboratory findings should the nurse expect?

Elevated BUN

Hypercalcemia

Metabolic alkalosis

Hypokalemia

Answer and Explanation

The Correct Answer is A

Choice A reason: In acute kidney injury (AKI), the blood urea nitrogen (BUN) level is expected to be elevated due to the kidneys' impaired ability to excrete urea, which is a waste product of protein metabolism. Normal BUN levels range from approximately 7 to 20 mg/dL.

Choice B reason: Hypercalcemia is not commonly associated with AKI. Instead, patients with AKI may experience hypocalcemia due to the kidneys' reduced ability to convert vitamin D to its active form, which is necessary for calcium absorption.

Choice C reason: Metabolic alkalosis is not a typical finding in AKI. More commonly, patients with AKI experience metabolic acidosis because the kidneys are unable to excrete acid effectively, leading to an accumulation of acid in the body.

Choice D reason: Hypokalemia is generally not expected in AKI. The condition is more often associated with hyperkalemia, as the impaired kidney function leads to a reduced excretion of potassium, which can accumulate to dangerous levels.

Correct Answer is B

Explanation

Choice A reason: This statement is incorrect because, during dehydration, water does not move towards areas of lower sodium concentration.

Choice B reason: This is correct because, during dehydration, the body retains sodium, and water follows by osmosis to areas where sodium concentration is higher, which can result in elevated sodium levels.

Choice C reason: Sodium does not typically move across membranes in response to solute concentration gradients; water does.

Choice D reason: Water moves independently of sodium particles, not necessarily together, and it moves towards areas of higher solute concentration.

A. The client who had general anesthesia for back surgery 4 hours ago. B. The client who has a history of liver failure. C. The client who reported eating a diet high in calcium oxalate. D. The client who was treated with antibiotics for Staphylococcus aureus infection of the skin 2 weeks ago.

Correct Answer is A

Explanation

Choice A reason: General anesthesia can cause urinary retention due to its effects on the nervous system, which may temporarily impair the normal re?exes that control urination. This is particularly relevant in the immediate postoperative period.

Choice B reason: While liver failure can have many systemic effects, it is not directly associated with an increased risk of urinary retention. Urinary retention is more commonly related to factors affecting the urinary tract or nervous system.

Choice C reason: A diet high in calcium oxalate can contribute to kidney stones, but it does not directly increase the risk of urinary retention. Urinary retention typically involves an obstruction or nerve dysfunction.

Choice D reason: Antibiotic treatment for a skin infection, even one caused by Staphylococcus aureus, would not typically result in urinary retention. Urinary retention is usually related to urinary tract obstructions, medications, or nerve issues.
