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 ["15"]
Explanation
Step 1: The total amount of amantadine required per dose is 150 mg.
Step 2: Each 5 mL of syrup contains 50 mg of amantadine.
Step 3: To find out how many mL are needed, we divide the total amount required by the amount in each 5 mL of syrup. So, (150 mg ÷ 50 mg/5 mL).
Step 4: The result is 15 mL.
So, the nurse should administer 15 mL per dose. This is already a whole number, so no rounding is necessary.
Correct Answer is D
Explanation
Choice A reason: A hemoglobin level of 16 g/dL is within the normal range and does not indicate acute kidney injury.
Choice B reason: A BUN level of 15 mg/dL is also within the normal range and does not suggest acute kidney injury.
Choice C reason: A serum potassium level of 4.5 mEq/L is within the normal range and is not indicative of acute kidney injury.
Choice D reason: A serum creatinine level of 6 mg/dL is significantly elevated and indicates impaired kidney function, which is a hallmark of acute kidney injury.
