A nurse is reviewing the laboratory test results from a client who has prerenal acute kidney injury (AKI). Which of the following electrolyte imbalances should the nurse expect?
Hypernatremia
Hypophosphatemia
Hypercalcemia
Hyperkalemia
The Correct Answer is D
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 C reason: Hypomagnesemia is not commonly associated with corticosteroid therapy.
Choice D reason: Hypermagnesemia is not typically induced by corticosteroid therapy.
Correct Answer is C

Choice A reason: Increased urinary output is not typically associated with peritonitis, especially during peritoneal
dialysis.
Choice B reason: Bradycardia, or a slow heart rate, is not a common manifestation of peritonitis.
Choice C reason: Nausea and vomiting are common symptoms of peritonitis and should be monitored in clients
receiving peritoneal dialysis.
