A patient’s Child–Pugh score needs to be calculated. The lab values and clinical findings are:
Total bilirubin: 2.6 mg/dL
Ascites: mild
Serum albumin: 2.9 g/dL
Hepatic encephalopathy: markedly lethargic and drowsy (severe)
Prothrombin time: 36 sec, with control = 12 sec
What is the total Child–Pugh score?
