A nurse is caring for a client admited with renal calculus. Which of the following assessment findings should the nurse associate with renal calculi? (Select all that apply)

 

Choice A reason: During the oliguric phase of acute kidney injury, BUN and creatinine levels typically increase, not decrease, due to reduced kidney function.

Choice B reason: Renal function is not reestablished during the oliguric phase; this phase is characterized by decreased function.

Choice C reason: The oliguric phase is defined by significantly reduced urine output, often less than 400 mL per 24 hours.

Choice D reason: The GFR does not recover during the oliguric phase; it is usually decreased.

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.
