A client with acute kidney injury (AKI) is admitted with an elevated heart rate and an elevated blood pressure. Which intervention should the practical nurse (PN) implement?

A. Monitoring daily sodium intake is important for managing AKI, but it is not the immediate priority when addressing acute changes in heart rate and blood pressure. B. Recording usual eating patterns is not relevant to the immediate concern of elevated heart rate and blood pressure in the context of AKI. C. Documenting abdominal girth is relevant for assessing fluid status and potential complications like ascites, but it is not the first priority for addressing the acute symptoms of elevated heart rate and blood pressure. D. Measuring and documenting urinary output is the most critical intervention because it provides essential information on kidney function and fluid balance, which directly impacts heart rate and blood pressure management in AKI.
