A client who has polycystic kidney disease (PKD) presents to the emergency department with reports of a severe headache. Which of the following complications should the nurse expect?

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.

Choice A reason: As CKD progresses, the kidneys' ability to filter blood decreases, leading to an increase in urine albumin, a sign of kidney damage.

Choice B reason: GFR would decrease, not increase, as CKD progresses because the kidneys' filtering capacity diminishes.

Choice C reason: Creatinine levels would increase, not decrease, as kidney function worsens in CKD.

Choice D reason: Proteinuria would increase, not decrease, as CKD progresses due to the kidneys' impaired filtering

ability
