Practice targeted AMC-style multiple-choice questions on diarrhea.
A 28-year-old male presents to the emergency department with severe abdominal pain, fever, and bloody diarrhea for the past 2 days. He has a known history of Crohn's disease, diagnosed 5 years ago, and has been managed with azathioprine. He admits to inconsistent adherence to his medication regimen over the past year due to feeling well. On examination, he is febrile (38.9°C), tachycardic (110 bpm), and hypotensive (90/60 mmHg). His abdomen is distended and tender to palpation, particularly in the lower quadrants, with guarding. Laboratory investigations reveal a white blood cell count of 18,000/mm³ with a left shift, hemoglobin of 10 g/dL, platelets of 450,000/mm³, albumin of 28 g/L, and C-reactive protein (CRP) of 150 mg/L. An abdominal X-ray shows dilated loops of bowel. Which of the following is the MOST appropriate next step in the management of this patient?
A 32-year-old male with Crohn's disease presents with worsening abdominal pain and diarrhea despite being on maintenance infliximab. The provided imaging was obtained. What is the MOST appropriate next step in management?
A 25-year-old man with Crohn's disease presents with increased abdominal pain and frequent diarrhea. He is on azathioprine. Stool studies are negative for infection. Which of the following is the most appropriate next step?
A 32-year-old male with a history of Crohn's disease presents with worsening abdominal pain, diarrhea, and a low-grade fever. He reports that his symptoms have been progressively worsening over the past few months despite being on maintenance therapy with azathioprine.

A 28-year-old female presents to her general practitioner with a 6-month history of intermittent abdominal pain, predominantly in the right lower quadrant. She describes the pain as cramping and associated with occasional episodes of non-bloody diarrhea. She denies fever, weight loss, or recent travel. Her past medical history is significant for well-controlled asthma, for which she uses an inhaled corticosteroid as needed. Physical examination reveals mild tenderness to palpation in the right lower quadrant, but is otherwise unremarkable. Bowel sounds are normal. Initial laboratory investigations, including a complete blood count and comprehensive metabolic panel, are within normal limits. Stool studies for ova and parasites, bacterial culture, and Clostridium difficile toxin are negative. Given her persistent symptoms, the GP refers her for further evaluation. A CT enterography is performed, and relevant images are shown. Based on the clinical presentation and imaging findings, which of the following is the MOST likely long-term complication this patient is at increased risk of developing?
