He also reports malaise and progressive shortness of breath, associated with slight exertion, for several weeks. The patient is a chronic drinker, and he was diagnosed with cirrhosis 2 years ago. He was warned to stop drinking alcohol, but he continues to drink. He hasnt accepted any more testing and has refused to visit the doctor until now. His vital signs are heart rate 62min, respiratory rate 26min, temperature 37.4C 99.3F, and blood pressure 11795 mm Hg. On physical examination, there is dyspnea and polypnea. Skin and sclera are jaundiced. The abdomen has visible collateral circulation and looks distended. There is diffuse abdominal pain upon palpation in the right hemiabdomen, and the liver is palpated 10 cm below the right costal border. The legs show significant edema. CT scan shows cirrhosis with portal hypertension and collateral circulation. During the fifth day of his hospital stay, the patient presents with oliguria and altered mental status.

A: Acute tubular necrosis, B: Chronic kidney disease, C: Glomerulonephritis, D: Hepatorenal syndrome, E: Pyelonephritis,  <response>: This is a patient with known cirrhosis who presents with signs of decompensated liver disease including jaundice, ascites, and hepatic encephalopathy. The key finding is the recent rise in creatinine in the setting of stable hematocrit and platelet count, making prerenal azotemia less likely. There are no signs of infection or glomerular disease based on the urinalysis. Therefore, the most likely diagnosis is hepatorenal syndrome, a form of functional renal failure that can occur in patients with advanced liver disease.D: Hepatorenal syndrome
