Part 1: Gastrointestinal & Hepatic Emergencies (Questions 1-12)
Q1: A 58-year-old male with cirrhosis presents with hematemesis and melena. BP is
88/52, HR 118, Hgb 7.2 g/dL. What is the immediate priority in management?
A. Immediate endoscopy to identify bleeding source
B. IV octreotide 50mcg bolus then 50mcg/hour infusion plus IV ceftriaxone
C. Oral beta-blocker to reduce portal pressure
D. Transjugular intrahepatic portosystemic shunt (TIPS) procedure
Correct Answer: B [CORRECT]
Rationale: Variceal hemorrhage requires immediate pharmacologic therapy with
octreotide (reduces splanchnic blood flow) plus prophylactic antibiotics
(ceftriaxone/ciprofloxacin) to prevent SBP and reduce mortality. Endoscopy (A) should
occur within 12 hours but hemodynamic stabilization and pharmacotherapy come first.
Beta-blockers (C) are for prevention, not acute bleeding. TIPS (D) is rescue therapy if
endoscopic treatment fails.
Q2: A 45-year-old alcoholic presents with severe epigastric pain radiating to the back,
nausea, and vomiting. Lipase is 2,850 U/L. CT shows pancreatic edema without
necrosis. Which Ranson criterion present at admission indicates higher severity?
,A. Age 45 years
B. WBC 16,000/μL
C. Blood glucose 140 mg/dL
D. AST 120 U/L
Correct Answer: B [CORRECT]
Rationale: Ranson criteria at admission: age >55, WBC >16,000, glucose >200, AST
>250, LDH >350. WBC 16,000 meets criterion. Age 45 (A) is under 55. Glucose 140 (C) is
under 200. AST 120 (D) is under 250. Score ≥3 indicates severe disease. This question
requires knowing specific Ranson cutoff values, not just general severity indicators.
Q3: A patient with cirrhosis and ascites develops fever, abdominal pain, and altered
mental status. Paracentesis shows PMN count 450 cells/μL. What is the diagnosis and
appropriate empiric therapy?
A. Culture-negative spontaneous bacterial peritonitis (SBP); start IV cefotaxime 2g q8h
or ceftriaxone 2g daily
B. Secondary peritonitis; urgent surgical consultation required
C. Culture-positive SBP requiring anaerobic coverage with metronidazole
D. Benign ascites; no antibiotics needed
Correct Answer: A [CORRECT]
Rationale: SBP diagnosed when ascitic fluid PMN ≥250 cells/μL with clinical suspicion.
Most common organisms are gram-negative enterics (E. coli, Klebsiella). Empiric
third-generation cephalosporin (cefotaxime, ceftriaxone) covers 95% of
,community-acquired SBP. Add albumin on day 1 and 3 to prevent HRS. Secondary
peritonitis (B) requires surgery but presents differently (multiple organisms, loculations,
free air).
Q4: A 72-year-old on warfarin (INR 3.5) presents with massive hematemesis. Which
blood product administration strategy is most appropriate?
A. FFP 15-20 mL/kg to reverse warfarin plus PRBCs as needed
B. Vitamin K 10mg IV only; takes 6-12 hours to reverse anticoagulation
C. 4-factor prothrombin complex concentrate (PCC) 25-50 units/kg plus vitamin K 10mg
IV for rapid reversal
D. Cryoprecipitate 10 units for fibrinogen replacement
Correct Answer: C [CORRECT]
Rationale: 4-factor PCC contains II, VII, IX, X and rapidly reverses warfarin (minutes) vs.
FFP (hours). PCC plus vitamin K provides immediate and sustained reversal. FFP (A)
requires large volumes and longer time. Vitamin K alone (B) takes too long for active
bleeding. Cryoprecipitate (D) replaces fibrinogen but doesn't reverse warfarin
anticoagulation.
Q5: A patient with hepatic encephalopathy (HE) grade 3 has asterixis and confusion.
Which medication mechanism best explains lactulose's efficacy?
A. Lactulose is absorbed and directly antagonizes ammonia in the brain
B. Lactulose is non-absorbable disaccharide converted to lactic/acetic acid by colonic
bacteria, acidifying gut and trapping ammonia (NH4+) for fecal excretion
, C. Lactulose induces hepatic enzyme production to metabolize ammonia
D. Lactulose is a diuretic that eliminates ammonia through kidneys
Correct Answer: B [CORRECT]
Rationale: Lactulose works through osmotic laxative effect and gut acidification.
Colonic bacteria metabolize lactulose to organic acids, lowering pH and converting
diffusible NH3 to non-diffusible NH4+ which is trapped and excreted. Rifaximin is
add-on therapy to reduce ammonia-producing gut bacteria. Options A, C, and D describe
non-existent mechanisms.
Q6: A 35-year-old with history of heavy alcohol use presents with hematemesis after
forceful retching. Endoscopy shows a 2cm linear mucosal tear at gastroesophageal
junction. What is the diagnosis?
A. Boerhaave syndrome (esophageal rupture)
B. Mallory-Weiss tear
C. Esophageal varix rupture
D. Dieulafoy lesion
Correct Answer: B [CORRECT]
Rationale: Mallory-Weiss tear is mucosal laceration at GE junction caused by forceful
retching/vomiting against closed glottis (alcohol-associated). Usually self-limited; 90%
stop bleeding spontaneously. Boerhaave (A) is transmural rupture with mediastinitis
(severe illness). Varices (C) occur with portal hypertension. Dieulafoy (D) is large
tortuous submucosal vessel without ulcer, usually gastric body.
