Domain 1: Gastrointestinal Acute Care (12 Questions)
Q1: A 68-year-old male presents with sudden onset of severe epigastric pain radiating to
the back, vomiting, and abdominal distension. Vital signs: BP 88/52 mmHg, HR 128
bpm, RR 24, Temp 38.2°C. Physical exam reveals epigastric tenderness with guarding
but no rebound. Laboratory studies show WBC 18,500/μL, lipase 2,850 U/L, glucose 248
mg/dL, BUN 42 mg/dL, creatinine 1.8 mg/dL, calcium 7.2 mg/dL, lactate 4.2 mmol/L.
CT abdomen shows pancreatic necrosis involving >30% of the gland with peripancreatic
fluid collections. Based on the BISAP score and clinical presentation, what is the most
appropriate immediate management priority?
A. Emergent endoscopic retrograde cholangiopancreatography (ERCP) within 24 hours
B. Immediate surgical debridement of necrotic pancreatic tissue
C. Aggressive fluid resuscitation with lactated Ringer's solution and ICU admission for
hemodynamic monitoring [CORRECT]
D. Initiation of prophylactic broad-spectrum antibiotics to prevent infected necrosis
Correct Answer: C
,Rationale: This patient has severe acute pancreatitis with BISAP score ≥3 (BUN >25,
impaired mental status implied by hemodynamic instability, SIRS criteria met with HR
>120 and WBC >12,000, age >60, and pleural effusion likely present given CT findings).
The immediate priority is aggressive fluid resuscitation with lactated Ringer's (preferred
over normal saline per randomized trials showing reduced SIRS and CRP levels) at
250-500 mL/hour or 5-10 mL/kg/hour initially, with careful hemodynamic monitoring.
ICU admission is warranted for hemodynamic instability requiring vasopressors.
Why other options are incorrect:
● A: ERCP is indicated only for acute biliary pancreatitis with cholangitis or
persistent biliary obstruction, not for necrotizing pancreatitis without biliary
obstruction.
● B: Early surgical intervention within the first 2 weeks increases mortality; necrotic
tissue debridement is delayed until walled-off necrosis develops (typically >4
weeks) and only if symptomatic or infected.
● D: Prophylactic antibiotics do not prevent infection of necrosis and are not
recommended; antibiotics are reserved for confirmed or suspected infected
necrosis (gas on CT or positive Gram stain/culture).
Q2: A 54-year-old female with history of diverticulosis presents with left lower quadrant
pain, fever, and change in bowel habits for 3 days. Vital signs: BP 142/88 mmHg, HR 96
bpm, Temp 38.8°C. CT abdomen reveals sigmoid diverticulitis with localized pericolic
fat stranding, no abscess, and no free air. She has no drug allergies. According to the
modified Hinchey classification and current guidelines, what is the most appropriate
antibiotic regimen?
A. Piperacillin-tazobactam 3.375 g IV every 6 hours monotherapy
B. Amoxicillin-clavulanate 875/125 mg PO every 12 hours for 5-7 days [CORRECT]
,C. Metronidazole 500 mg PO every 8 hours plus ciprofloxacin 500 mg PO every 12 hours
for 14 days
D. Immediate sigmoidectomy with primary anastomosis
Correct Answer: B
Rationale: This patient has uncomplicated acute diverticulitis (modified Hinchey Stage 0
or Ia—localized inflammation without abscess, perforation, or obstruction). Current
evidence supports outpatient management with oral antibiotics for uncomplicated
cases. Amoxicillin-clavulanate is preferred due to increasing fluoroquinolone resistance
and FDA warnings about fluoroquinolone adverse effects (tendon rupture, neuropathy,
aortic aneurysm). Duration is typically 5-7 days (shorter courses are being studied but
5-7 days remains standard).
Why other options are incorrect:
● A: Piperacillin-tazobactam is reserved for complicated diverticulitis (abscess,
perforation, sepsis) or failed outpatient therapy, not uncomplicated disease.
● C: Metronidazole plus ciprofloxacin was previously standard but
fluoroquinolones are no longer preferred first-line due to resistance patterns and
safety concerns; 14 days is excessive for uncomplicated disease.
● D: Surgery is indicated for complicated diverticulitis (Hinchey stages III-IV),
failure of medical management, or recurrent episodes (typically after >2-3
episodes), not for initial uncomplicated presentation.
Q3: A 72-year-old male with atrial fibrillation on warfarin presents with acute severe
abdominal pain out of proportion to physical exam findings. Vital signs: BP 94/60
mmHg, HR 118 bpm (irregularly irregular), RR 22. Abdomen is soft with mild diffuse
, tenderness but no guarding or rebound. Lactate is 6.8 mmol/L. What is the most
appropriate immediate diagnostic and management approach?
A. CT angiography of the abdomen and pelvis with immediate anticoagulation reversal
[CORRECT]
B. Emergent exploratory laparotomy without imaging
C. Duplex ultrasound of the mesenteric vessels
D. Upper endoscopy to evaluate for peptic ulcer disease
Correct Answer: A
Rationale: This presentation is classic for acute mesenteric ischemia (AMI)—severe
pain out of proportion to exam findings ("pain out of proportion" sign), atrial fibrillation
(embolic risk), elevated lactate, and hemodynamic compromise. CT angiography (CTA)
is the gold standard diagnostic test with sensitivity and specificity >90% for detecting
vascular occlusion. Immediate anticoagulation reversal with 4-factor prothrombin
complex concentrate (PCC) plus vitamin K is critical given warfarin use and need for
potential intervention.
Why other options are incorrect:
● B: While surgical exploration may ultimately be needed, preoperative CTA defines
the vascular anatomy, identifies embolic vs. thrombotic etiology, and guides
intervention (endovascular vs. open).
● C: Duplex ultrasound is operator-dependent, limited by bowel gas in acute
abdomen, and cannot adequately visualize the entire mesenteric circulation; it's
inadequate for AMI diagnosis.
● D: Upper endoscopy evaluates mucosal lesions but cannot diagnose vascular
compromise; delaying CTA for endoscopy risks catastrophic bowel infarction.
