Question 1
A patient is diagnosed with low rectal cancer located distal to the dentate line. Which
surgical procedure is most appropriate for this condition?
A. Low anterior resection (LAR)
B. Ileal pouch anal anastomosis (IPAA)
C. Abdominoperineal resection (APR)
D. Sigmoid colectomy
Correct Answer: C. Abdominoperineal resection (APR)
Rationale: APR is indicated for very low rectal tumors below the dentate line where
sphincter preservation is not possible. It involves removal of the rectum and anus with
permanent colostomy formation. LAR and IPAA are sphincter-preserving procedures
used for higher lesions, while sigmoid colectomy is not appropriate for rectal cancer
management.
Question 2
Which condition most commonly requires an ileal pouch anal anastomosis (IPAA)?
A. Crohn’s disease
B. Ulcerative colitis and familial adenomatous polyposis
C. Diverticulitis
D. Irritable bowel syndrome
Correct Answer: B. Ulcerative colitis and familial adenomatous polyposis
Rationale: IPAA is primarily indicated for ulcerative colitis and familial adenomatous
polyposis because both conditions require total colectomy. Crohn’s disease is
generally not suitable due to risk of recurrence in the pouch. IBS and diverticulitis do
not require this surgery.
Question 3
,2026/2027
A patient with Crohn’s disease is most likely to present with which symptom during
disease recurrence?
A. Bloody diarrhea only
B. Obstructive abdominal pain
C. Absence of perianal disease
D. Rectal sparing with no symptoms
Correct Answer: B. Obstructive abdominal pain
Rationale: Crohn’s disease causes transmural inflammation that may lead to strictures
and bowel obstruction, resulting in crampy or obstructive abdominal pain. Bloody
diarrhea is more typical of ulcerative colitis. Perianal disease is common in Crohn’s,
not absent.
Question 4
Which statement correctly describes ulcerative colitis?
A. Transmural inflammation with skip lesions
B. Begins in the rectum and extends proximally
C. Affects the entire GI tract
D. Causes fistula formation frequently
Correct Answer: B. Begins in the rectum and extends proximally
Rationale: Ulcerative colitis starts in the rectum and spreads continuously upward. It
is limited to the colon and involves only mucosal layers. Skip lesions and transmural
involvement are features of Crohn’s disease.
Question 5
Which medication class is commonly used in the management of Crohn’s disease?
A. Anticholinergics only
B. Corticosteroids and immunosuppressants
C. Antidepressants
D. Antihistamines
Correct Answer: B. Corticosteroids and immunosuppressants
Rationale: Crohn’s disease is treated with anti-inflammatory and immune-modulating
drugs such as corticosteroids and immunosuppressants. Anticholinergics and
antihistamines are not effective, and antidepressants are not primary therapy.

Question 6
The preferred location for an adult ileostomy is:
A. Left lower quadrant
B. Right lower quadrant
C. Right upper quadrant
D. Left upper quadrant
Correct Answer: B. Right lower quadrant
Rationale: The ileum is anatomically located in the right lower quadrant, making this
the preferred and most functional stoma site for ileostomy creation.
Question 7
Which type of stoma construction is NOT completely diverting?
A. End stoma
B. Loop stoma
C. Double barrel stoma
D. Brooke ileostomy
Correct Answer: B. Loop stoma
Rationale: Loop stomas allow partial fecal diversion because both proximal and distal
limbs may still communicate. End and double-barrel stomas are fully diverting
procedures.
Question 8
The most corrosive stoma effluent is expected from:
A. Sigmoid colostomy
B. Ileostomy
C. Descending colostomy
D. Transverse colostomy
Correct Answer: B. Ileostomy
Rationale: Ileostomy output contains digestive enzymes that are highly alkaline and
irritating to skin, making it the most corrosive. Colostomy output is more formed and
less irritating.
Question 9
, 2026/2027
A 7-month-old infant with suspected Hirschsprung’s disease will most likely undergo:
A. Loop ileostomy
B. Diverting colostomy
C. End colostomy
D. Ileal conduit
Correct Answer: B. Diverting colostomy
Rationale: Hirschsprung’s disease causes functional bowel obstruction; initial
management often involves diverting colostomy to decompress the bowel before
definitive repair.
Question 10
A complication that almost always requires surgical intervention in diverticular
disease is:
A. Inflammation
B. Microperforation
C. Diverticulum formation
D. Bowel perforation
Correct Answer: D. Bowel perforation
Rationale: Full bowel perforation leads to peritonitis and requires urgent surgical
intervention. Mild inflammation or microperforation may be managed conservatively.
Question 11
Which symptom cluster is most consistent with diverticulitis?
A. RUQ pain, fever, malaise
B. RLQ pain, vomiting
C. LLQ pain, fever, nausea/vomiting
D. Dysuria only
Correct Answer: C. LLQ pain, fever, nausea/vomiting
Rationale: Diverticulitis typically affects the sigmoid colon, causing left lower
quadrant pain with systemic signs like fever and nausea.
Question 12
A temporary loop ileostomy is primarily created to:
