Internal Medicine Exam Chronic Liver Disease Complications 3 — Questions and Answers
Question 1: A patient with alcoholic cirrhosis presents with acute upper GI bleeding. Endoscopy shows actively bleeding esophageal varices treated with band ligation. Which medication should be started immediately upon admission?
- Pantoprazole IV infusion
- Octreotide IV infusion (Correct answer)
- Propranolol orally
- Furosemide IV
Correct answer: Octreotide IV infusion
Octreotide (or terlipressin) reduces splanchnic blood flow and portal pressure; it should be started at admission and continued for 3–5 days during acute variceal hemorrhage.
Question 2: Which of the following is the strongest independent risk factor for spontaneous bacterial peritonitis (SBP) in cirrhotic patients with ascites?
- Serum albumin <2.5 g/dL
- Ascitic fluid protein <1.5 g/dL (Correct answer)
- Platelet count <100,000/μL
- Child-Pugh class B
Correct answer: Ascitic fluid protein <1.5 g/dL
Low ascitic fluid protein (<1.5 g/dL) reflects reduced opsonic activity and is the strongest independent risk factor for SBP in cirrhotic ascites.
Question 3: A cirrhotic patient with known varices has not bled. What is the recommended primary prophylaxis approach for large varices?
- Sclerotherapy alone
- Non-selective beta-blockers or endoscopic band ligation (Correct answer)
- TIPS procedure
- Shunt surgery
Correct answer: Non-selective beta-blockers or endoscopic band ligation
Non-selective beta-blockers (propranolol, nadolol, carvedilol) or endoscopic band ligation are equally effective first-line primary prophylaxis for large esophageal varices.
Question 4: A patient with cirrhosis and hepatic encephalopathy is found to have hyponatremia (Na 121 mEq/L). Which treatment is most appropriate?
- Rapid sodium correction with 3% saline
- Fluid restriction and consideration of vaptans (Correct answer)
- Isotonic saline infusion
- Increased diuretic doses
Correct answer: Fluid restriction and consideration of vaptans
Dilutional hyponatremia in cirrhosis is managed with fluid restriction; vasopressin receptor antagonists (vaptans) may be used in resistant cases.
Question 5: Which complication of cirrhosis is characterized by intrapulmonary vascular dilatations leading to hypoxemia that improves with 100% oxygen administration?
- Portopulmonary hypertension
- Hepatopulmonary syndrome (Correct answer)
- Hepatic hydrothorax
- Transfusion-related acute lung injury
Correct answer: Hepatopulmonary syndrome
Hepatopulmonary syndrome results from intrapulmonary vasodilation causing V/Q mismatch and right-to-left shunting, with PaO2 improving on 100% O2.
Question 6: A cirrhotic patient with tense ascites undergoes large-volume paracentesis (5 liters removed) without albumin infusion. What complication is most likely to occur within 6 hours?
- Refeeding syndrome
- Paracentesis-induced circulatory dysfunction (Correct answer)
- Spontaneous bacterial peritonitis
- Hepatic encephalopathy
Correct answer: Paracentesis-induced circulatory dysfunction
Paracentesis-induced circulatory dysfunction (PICD) occurs when >5L is removed without albumin replacement, causing plasma renin activation and renal/circulatory compromise.
Question 7: Which finding on ascitic fluid analysis most reliably distinguishes SBP from secondary bacterial peritonitis?
- Ascitic fluid glucose <50 mg/dL
- PMN count >250 cells/mm³ with single organism on culture
- Lactate dehydrogenase elevated in ascitic fluid
- Ascitic fluid protein >1 g/dL with multiple organisms (Correct answer)
Correct answer: Ascitic fluid protein >1 g/dL with multiple organisms
Secondary peritonitis typically shows multiple organisms on culture, high protein, high LDH, and low glucose in ascitic fluid, distinguishing it from SBP.
A patient with alcoholic cirrhosis presents with acute upper GI bleeding.
Endoscopy shows actively bleeding esophageal varices treated with band ligation.
