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.

Choice C reason: Consuming adequate fluids is important to help ?ush bacteria from the urinary tract.
Choice D reason: Completing all antibiotics as prescribed is crucial to ensure the infection is fully treated and to prevent resistance.
Choice E reason: Wiping from front to back helps prevent bacteria from the anal area from spreading to the urethra.
Correct Answer is C
Explanation
Choice A reason: Flatened neck veins would suggest dehydration rather than fluid overload.
Choice B reason: The return of skin to previous position when pinched indicates good skin turgor, not fluid overload.
Choice C reason: A significant weight gain in a short period, such as 5 lb since yesterday, is a classic sign of fluid overload.
Choice D reason: An oxygen saturation of 93% does not necessarily indicate fluid overload.
