A nurse is monitoring an older adult female client who had a myocardial infarction (MI) for the development of acute kidney injury (AKI). Which of the following findings should the nurse identify as indicating an increased risk of AKI?
 

Choice A reason: The normal range for serum creatinine in adult females is approximately 0.6–1.1 mg/dL. A level of 1.8 mg/dL is elevated and indicates impaired kidney function, which is a risk factor for AKI.

Choice B reason: Normal BUN levels are generally between 6 to 24 mg/dL⁸. A BUN level of 200 mg/dL is significantly elevated and suggests kidney dysfunction, which can lead to AKI.

Choice C reason: Serum osmolality in the normal range, which is typically between 275 to 295 mOsm/kg H2O for adults⁹[13][^10^][14][16], does not indicate an increased risk of AKI.

Choice D reason: The normal range for serum magnesium is typically 1.7 to 2.2 mg/dL or 0.85 to 1.10 mmol/L. A level of 2.0 mEq/L (which is equivalent to 2.0 mg/dL) is within the normal range and does not indicate an increased risk for AKI.

Choice A reason: Maintaining the client in a left lateral position is not specifically required for peritoneal dialysis. Positioning may vary based on the individual's comfort and specific medical needs.

Choice B reason: While monitoring vital signs is important during any medical procedure, it is not an intervention that directly ensures proper dialysate exchange in peritoneal dialysis.

Choice C reason: Warming the dialysate solution prior to instillation is a standard practice in peritoneal dialysis. It helps to promote patient comfort and more efficient exchange of wastes and fluids.

Choice D reason: Placing the drainage bag above the level of the client's abdomen would impede gravity drainage, which is necessary for proper dialysate exchange. The drainage bag should be placed below the level of the client's abdomen.
