The nurse is caring for a client in the emergency department. Exhibits Select the 3 complications the client is at risk for developing.

Rationale: A. Chronic Kidney Disease (CKD): The elevated BUN and creatinine levels, along with the client's decreased urine output and fluid retention, suggest impaired kidney function, increasing the risk for chronic kidney disease, especially with underlying comorbidities. B. Hyperglycemia: There are no signs or symptoms indicating hyperglycemia, so hyperglycemia is unlikely to be a concern in this case based on the presented findings. C. Uremia: Uremia occurs when waste products accumulate in the blood due to renal dysfunction, and the elevated BUN and creatinine, combined with symptoms like fatigue and dyspnea, indicate this condition in the client. D. Hyperkalemia: Impaired kidney function limits potassium excretion, increasing the risk for hyperkalemia. Given the client’s kidney impairment, this can lead to elevated potassium levels and potentially cause life-threatening arrhythmias. E. Polycystic Kidney Disease: Polycystic kidney disease typically presents with a gradual onset of symptoms like kidney enlargement and a family history, which the client’s acute presentation does not support, making PKD an unlikely diagnosis.
