SUCCESS WITH DETAILED RATIONALES
Diverticulitis is:
A. Chronic inflammation of the liver
B. Inflammation/infection of diverticula (small pouches) in the intestine
C. A type of peptic ulcer
D. Viral gastroenteritis
Rationale: Diverticulitis = infected/inflamed diverticula.
The pathophysiology of diverticulitis most often involves:
A. Viral infection of mucosa
B. High intraluminal pressure → diverticula form → trapped food/bacteria → inflammation
C. Autoimmune destruction of colon
D. Fatty infiltration of bowel wall
Rationale: Increased pressure and trapping of contents cause inflammation.
Major risk factors for diverticulitis include all EXCEPT:
A. Low fiber diet
B. Smoking
C. NSAID use
D. High daily fiber intake
Rationale: Low (not high) fiber diet is a risk factor.
Typical signs and symptoms of diverticulitis are:
A. RUQ pain and jaundice
B. Left lower-quadrant pain, bloating, fever, N/V
C. Severe vomiting only
D. Hematuria and flank pain
Rationale: LLQ pain is classic for sigmoid diverticulitis.
Diverticulitis labs often show:
A. Low WBC and low ESR
B. Increased WBC, ↑ ESR/CRP; low Hgb/Hct if bleeding
C. Elevated amylase only
D. Positive troponin
Rationale: Infection/inflammation produces leukocytosis and elevated inflammatory markers.
Best imaging to evaluate suspected acute diverticulitis is:
A. Chest x-ray
, ESTUDYR
B. Plain abdominal film only
C. CT abdomen/pelvis (often with contrast)
D. Echocardiogram
Rationale: CT provides accurate diagnosis and detects complications.
Initial treatment for uncomplicated diverticulitis usually includes:
A. Urgent surgery always
B. Antibiotics, analgesics, and bowel rest (NPO/clear liquids during flares)
C. High-residue diet immediately
D. Chemotherapy
Rationale: Medical management with antibiotics and bowel rest is first-line for uncomplicated cases.
Crohn’s disease differs from ulcerative colitis by:
A. Involving only the colon mucosa
B. Patchy “skip” lesions anywhere in GI and transmural inflammation
C. Never causing fistulas
D. Always responding to surgery curatively
Rationale: Crohn’s is transmural and can affect any GI segment; skip lesions are characteristic.
Common Crohn’s symptoms include:
A. Constipation only
B. Diarrhea (5–6 stools/day), steatorrhea, RLQ pain, weight loss, fever
C. Painless rectal bleeding only
D. Jaundice and pruritus
Rationale: Crohn’s often causes chronic diarrhea, malabsorption, and RLQ pain.
Important labs/findings in Crohn’s disease:
A. Elevated Hct/Hgb and low ESR
B. Low Hct/Hgb (anemia), low albumin, ↑ ESR/CRP, ↑ WBC
C. Positive H. pylori only
D. Highly elevated lipase always
Rationale: Inflammation and malabsorption lead to anemia and inflammatory markers.
Crohn’s medical treatments commonly include:
A. Proton pump inhibitors only
B. Aminosalicylates (sulfasalazine), corticosteroids, biologics (infliximab), antidiarrheals
C. High-dose insulin
D. Antivirals
Rationale: Anti-inflammatory and immunomodulatory drugs form core therapy.
Surgical options for Crohn’s may include:
A. Gastric bypass only
B. Small bowel resection, colectomy, ileostomy for complications
C. Appendectomy only
