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 B reason: Females do have a shorter urethra than males, which makes it easier for bacteria to reach the bladder and cause infections.
Choice C reason: While E. coli is a common bacteria causing UTIs, stating that females have more E. coli is incorrect and not a reason for increased UTIs.
Choice D reason: Sexual activity can increase the risk of UTIs, but it is not appropriate to assume that the client's age correlates with increased sexual activity.
