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.

Correct Answer is D
Explanation
Choice A reason: Measuring blood pressure di?erences is not a method to assess the patency of an AV graft.
Choice B reason: Checking pulses is important but does not confirm the patency of the AV graft.
Choice C reason: Using a Doppler stethoscope at the antecubital fossa is not the standard method for assessing AV graft patency.
Choice D reason: Auscultating for a bruit at the site of the AV graft is a common and non-invasive way to assess for patency.
Correct Answer is D
Explanation
Choice A reason: Blood-tinged dialysate outflow can occur initially due to the surgical procedure and is not typically a cause for immediate concern unless it persists or is accompanied by other symptoms.
Choice B reason: Dialysate leakage during inflow might indicate a problem with the catheter placement or integrity but is not usually an emergency. It should be monitored and reported if it continues.
Choice C reason: Discomfort during dialysate inflow is common, especially in new patients, as they adjust to the sensation of fluid being infused. It should be reported if the discomfort is severe or persistent.
Choice D reason: Purulent dialysate outflow indicates an infection, such as peritonitis, which is a serious complication
of peritoneal dialysis. This requires immediate atention and intervention by the healthcare provider.
