A client is being treated for chronic kidney disease (CKD). On examination, the client has elevated blood pressure (BP) and is exhibiting changes in mental status. Which intervention in the plan of care should the practical nurse (PN) implement?

A. Using a cushion when sitting may provide comfort, but it does not directly address the client's elevated blood pressure or changes in mental status related to chronic kidney disease (CKD). B. Weighing every morning is crucial in managing CKD, particularly with elevated blood pressure, as it helps monitor fluid retention, which can indicate worsening kidney function or fluid overload. This intervention is essential for assessing the client's condition and adjusting treatment as needed. C. Performing range of motion exercises is important for maintaining mobility, especially in an immobile client; however, it does not directly address the pressing issues of elevated blood pressure and altered mental status. D. Documenting abdominal girth can be important for assessing fluid retention, but it is less immediate than daily weight monitoring for a client with CKD showing significant symptoms.
