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?
Serum creatinine 1.8 mg/dL
Blood urea nitrogen (BUN) 200 mg/dL
Serum osmolality 290 mOsm/kg H2O
Magnesium 2.0 mEq/L
Correct Answer : A,B
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.

Correct Answer is C
Explanation
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.
Correct Answer is C
Explanation
Choice A reason: Dizziness can be a symptom of DKA due to dehydration; however, it is not as specific as mental status changes.
Choice B reason: Nervousness is not a specific symptom of DKA and can be related to high blood glucose levels rather than DKA itself.
Choice C reason: Mental status changes such as confusion or altered consciousness are significant indicators of DKA and require immediate medical atention.
Choice D reason: Cool, clammy skin is not typically associated with DKA; instead, DKA can present with dry skin and mouth due to dehydration.
