A patient is diagnosed with Acute viral hepatitis. Which is the most appropriate management principle?
A. Give IV antibiotics and arrange urgent biliary decompression when obstruction with significant cholangitis is present
B. Provide supportive care for uncomplicated disease and urgently evaluate any evidence of acute liver failure
C. Use severity-appropriate anti-inflammatory therapy; severe acute colitis requires hospital-based management
D. Use sodium restriction and appropriate diuretic therapy; perform therapeutic paracentesis for tense ascites
Correct Answer: B
Management depends on the virus and severity; acute liver failure requires specialist and critical-care management.
Medicine
Gastroenterology & Hepatology
In a patient with suspected Acute viral hepatitis, which investigation or diagnostic approach is most appropriate at this stage?

B. Serum lipase plus targeted imaging when diagnosis, severity or biliary cause requires clarification
C. Liver tests and biliary imaging, usually starting with ultrasound
D. Colonoscopy with biopsies when safe and appropriate
Correct Answer: A
Serology identifies the viral cause while INR and other measures assess hepatic synthetic function and severity.

Which complication or major adverse outcome is particularly associated with Hepatic encephalopathy?
A. Acute liver failure

A patient is diagnosed with Hepatic encephalopathy. Which is the most appropriate management principle?
A. Treat the precipitant and use lactulose, adding other ammonia-lowering therapy when indicated
B. Use sodium restriction and appropriate diuretic therapy; perform therapeutic paracentesis for tense ascites
C. Provide supportive care for uncomplicated disease and urgently evaluate any evidence of acute liver failure
D. Stabilize airway and circulation, establish IV access, resuscitate appropriately and arrange urgent endoscopic therapy
Correct Answer: A
Lactulose reduces intestinal ammonia absorption and is standard initial therapy.

In a patient with suspected Hepatic encephalopathy, which investigation or diagnostic approach is most appropriate at this stage?
A. Colonoscopy with biopsies when safe and appropriate
B. Diagnostic paracentesis for new or clinically significant ascites
C. Liver profile, coagulation status and targeted viral serology
D. Clinical assessment plus a search for precipitating factors such as infection, bleeding, electrolyte disturbance or constipation
Correct Answer: D
Hepatic encephalopathy is primarily clinical; finding and correcting the precipitating factor is essential.

A patient has cirrhosis with confusion, sleep-pattern reversal and asterixis after a gastrointestinal bleed. What is the most likely diagnosis?
A. Acute ascending cholangitis
B. Ulcerative colitis
C. Hepatic encephalopathy
D. Decompensated cirrhosis with ascites
Correct Answer: C
Altered cognition and asterixis in decompensated liver disease with a precipitant are typical of hepatic encephalopathy.

A cirrhotic patient with ascites develops fever and abdominal pain. What should be performed promptly?
A. Elective colonoscopy first
B. Diagnostic paracentesis
C. Barium swallow
D. Routine exercise stress test
Correct Answer: B
Possible spontaneous bacterial peritonitis requires prompt ascitic-fluid analysis.
Medicine
Gastroenterology & Hepatology
Which complication or major adverse outcome is particularly associated with Decompensated cirrhosis with ascites?
A. Spontaneous bacterial peritonitis
B. Perforated peptic ulcer
C. Pancreatic necrosis
D. Septic shock
Correct Answer: A
Cirrhotic ascites predisposes to spontaneous bacterial infection with high morbidity and mortality.

A patient is diagnosed with Decompensated cirrhosis with ascites. Which is the most appropriate management principle?
A. Stabilize airway and circulation, establish IV access, resuscitate appropriately and arrange urgent endoscopic therapy
B. Use an evidence-based H. pylori eradication regimen and confirm eradication after treatment
C. Provide early supportive care with appropriate IV fluids, analgesia and early enteral nutrition as tolerated
D. Use sodium restriction and appropriate diuretic therapy; perform therapeutic paracentesis for tense ascites
Correct Answer: D
Ascites treatment depends on severity and kidney function; large-volume paracentesis is used for tense symptomatic ascites.
Medicine
Gastroenterology & Hepatology
In a patient with suspected Decompensated cirrhosis with ascites, which investigation or diagnostic approach is most appropriate at this stage?
A. Liver profile, coagulation status and targeted viral serology
B. Urgent upper endoscopy after initial stabilization
C. Diagnostic paracentesis for new or clinically significant ascites
D. Test for active H. pylori infection using an appropriate noninvasive or biopsy-based method
Correct Answer: C
Ascitic-fluid analysis evaluates portal-hypertensive physiology and excludes spontaneous bacterial peritonitis.

A patient has chronic liver disease, abdominal distension, shifting dullness and peripheral edema. What is the most likely diagnosis?
A. Hepatic encephalopathy
B. Decompensated cirrhosis with ascites
C. Acute viral hepatitis
D. Acute upper gastrointestinal bleeding
Correct Answer: B
Ascites in chronic liver disease is a major marker of hepatic decompensation.
