It demonstrates irreversible peripheral nerve damage

It indicates acute spinal cord dysfunction

It excludes metabolic causes of altered consciousness

None

A 56-year-old man with chronic hepatitis C has progressive abdominal distension, bilateral pedal edema and easy bruising. Examination reveals ascites, splenomegaly and spider angiomas.

Spontaneous bacterial peritonitis

None

A 53-year-old man with cirrhosis is brought to hospital because of confusion. He is lethargic but responds to verbal commands, is disoriented to time and has asterixis. Which grade of hepatic encephalopathy is most consistent with these findings?

West Haven Grade I

West Haven Grade II

West Haven Grade III

West Haven Grade IV

No hepatic encephalopathy

None

10.

A 55-year-old man with chronic hepatitis C presents with new-onset ascites. Diagnostic paracentesis reveals a serum albumin concentration of 2.8 g/dL and ascitic fluid albumin of 1.0 g/dL. The ascitic neutrophil count is 80 cells/mm³. What is the most appropriate interpretation?

High-SAAG ascites consistent with portal hypertension

Low-SAAG ascites suggesting peritoneal malignancy

Ascitic fluid findings diagnostic of bacterial peritonitis

Ascites caused primarily by pancreatic inflammation

Ascites unrelated to hepatic vascular pressure

None

11.

A 58-year-old man with cirrhosis is admitted with fever and worsening ascites. Diagnostic paracentesis reveals an ascitic fluid polymorphonuclear leukocyte count of 420 cells/mm³. The bacterial culture result is pending. Which interpretation is most appropriate?

The result excludes infection because culture confirmation is unavailable

The neutrophil count is expected in uncomplicated cirrhotic ascites

The result is diagnostic of spontaneous bacterial peritonitis and warrants treatment

The findings indicate malignant ascites without infection

The result establishes secondary peritonitis requiring immediate surgery

None

12.

A 60-year-old man with decompensated cirrhosis has serum bilirubin of 4.2 mg/dL, albumin 2.3 g/dL and INR 2.0. He also has clinically evident ascites. Which interpretation best explains the albumin and INR abnormalities?

Preserved liver synthetic function despite hyperbilirubinemia

Isolated hemolysis without hepatocellular dysfunction

Increased hepatic synthesis of albumin and clotting factors

Impaired hepatic synthetic function due to advanced liver disease

Selective renal excretion of all coagulation factors

None

13.

A 56-year-old man with cirrhosis undergoes diagnostic paracentesis for newly detected ascites. Ascitic fluid analysis reveals a serum-ascites albumin gradient of 1.6 g/dL with a neutrophil count of 90 cells/mm³. Which conclusion is most appropriate?

The findings establish spontaneous bacterial peritonitis

The findings favor peritoneal tuberculosis

The findings exclude portal hypertension

The findings establish primary peritoneal malignancy

The findings support portal hypertensive ascites without neutrocytic infection

None

14.

A 57-year-old man with decompensated cirrhosis presents with marked abdominal distension and discomfort. He is alert, afebrile and hemodynamically stable. Investigations confirm portal hypertensive ascites without infection or significant renal impairment. Which initial long-term management approach is most appropriate?

Dietary sodium restriction with appropriate diuretic therapy and monitoring

Routine broad-spectrum antibiotics without evidence of infection

Unrestricted sodium intake combined with increased oral fluids

Immediate surgical exploration to drain the peritoneal cavity

Permanent discontinuation of all fluid-balance monitoring
