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 A
Explanation
Choice A reason: As CKD progresses, the kidneys' ability to filter blood decreases, leading to an increase in urine albumin, a sign of kidney damage.
Choice B reason: GFR would decrease, not increase, as CKD progresses because the kidneys' filtering capacity diminishes.
Choice C reason: Creatinine levels would increase, not decrease, as kidney function worsens in CKD.
Choice D reason: Proteinuria would increase, not decrease, as CKD progresses due to the kidneys' impaired filtering
ability
.
Correct Answer is D
Explanation
Choice A reason: Furosemide does not require a diet low in potassium; in fact, patients may need to increase their potassium intake due to its diuretic effect.
Choice B reason: Patients on furosemide should not limit fluid intake unless specifically instructed by their healthcare provider, as the medication is a diuretic.
Choice C reason: Furosemide is used to treat high blood pressure, so it would not cause an increase in blood pressure.
Choice D reason: Limiting sun exposure and wearing sunscreen is important as furosemide can make the skin more sensitive to sunlight.
