Given the patient's elevated creatinine level of 2.5 mg/dL, which of the following is the most appropriate clinical interpretation considering the current medication regimen?
The elevated creatinine is likely due to the use of Simvastatin, which is known to affect renal function. The creatinine level is within the normal range and does not require further investigation. The patient may have renal impairment, which could be exacerbated by the use of Naproxen. The creatinine level suggests dehydration, requiring increased fluid intake.
