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 B
Explanation
Choice A reason: The pH of urine can vary, but having a more alkalotic urine does not necessarily promote the growth of bacteria. Urine is typically slightly acidic, which helps to prevent bacterial growth.
Choice B reason: The primary anatomical reason for the higher rates of UTIs in clients who have vaginas is the shorter length of the urethra compared to those who do not have vaginas. This shorter distance makes it easier for bacteria from the skin or rectal area to enter the bladder.
Choice C reason: The strength of the detrusor muscle, which controls the emptying of the bladder, does not have a direct correlation with the frequency of UTIs. UTIs are more related to bacterial invasion rather than muscle strength.
Choice D reason: Bladder capacity is generally not a factor in the frequency of UTIs. While residual urine can increase the risk of UTIs, this is not typically related to overall bladder capacity.
Correct Answer is A
Explanation
Choice A reason: General anesthesia can impair the autonomic nervous system, which controls bladder function, leading to urinary retention. This risk is particularly high shortly after surgery.
Choice B reason: While liver failure can lead to multiple organ dysfunction, it is not directly associated with urinary retention unless there are concurrent issues affecting the urinary system.
Choice C reason: A diet high in calcium oxalate can contribute to kidney stones, which could potentially cause urinary obstruction, but it is not a direct cause of urinary retention.
Choice D reason: Antibiotics for a skin infection would not typically lead to urinary retention unless there were an allergic reaction or other rare side effects that affect the urinary system.
