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: Hypernatremia, which is an abnormally high level of sodium in the blood, is not typically associated with prerenal AKI. Prerenal AKI is often related to hypovolemia, which can lead to hyponatremia rather than hypernatremia.

Choice B reason: Hypophosphatemia, or low levels of phosphate in the blood, is not a common finding in prerenal AKI. Phosphate levels are more often affected in intrinsic renal diseases or refeeding syndrome.

Choice C reason: Hypercalcemia, or high levels of calcium in the blood, is not commonly seen in prerenal AKI. It is more frequently associated with malignancies or hyperparathyroidism.

Choice D reason: Hyperkalemia, which is an elevated level of potassium in the blood, is a common electrolyte imbalance in prerenal AKI. This occurs due to decreased renal perfusion and the kidney's reduced ability to excrete potassium.

Choice A reason: A diet high in calcium oxalate-rich foods should be avoided as it can contribute to the formation of calcium oxalate stones.

Choice B reason: Continuing prescribed gout medication is important, but it does not directly prevent the formation of renal calculi unless the medication is specifically for reducing uric acid levels.

Choice C reason: Drinking plenty of fluids, especially water, is one of the most effective ways to prevent the recurrence of renal calculi by diluting the urine and reducing the concentration of stone-forming minerals.

Choice D reason: A diet high in purine-rich foods can increase the risk of uric acid stones and should be avoided, especially in patients with gout and a history of renal calculi.
