Question 1
The patient who is NPO for several days is at risk for atrophy of which of the
following structures in the mucosal surface of the small bowel?
• A) Ligament of Treitz
• B) Villi
• C) Ampulla of Vater
• D) Sphincter of Oddi
Correct Answer: B - Villi
Rationale: The villi are finger-like projections on the small bowel mucosa
responsible for nutrient absorption. Lack of enteral nutrition (NPO status)
leads to villous atrophy because these cells require direct contact with
nutrients to maintain their structure and function. The Ligament of Treitz is a
suspensory muscle, the Ampulla of Vater is a duct opening, and the Sphincter
of Oddi controls bile flow—none atrophy with NPO status.
,Question 2
A bowel prep preoperatively for ostomy surgery is routinely utilized to
decrease bacteria in the bowel. The section of the bowel with the greatest
level of bacteria is:
• A) Distal portion of the colon
• B) Proximal portion of the colon
• C) Distal portion of the small bowel
• D) Proximal portion of the small bowel
Correct Answer: A - Distal portion of the colon
Rationale: Bacterial concentration increases progressively along the
gastrointestinal tract, with the highest concentration in the distal colon
(sigmoid colon and rectum). The small bowel has relatively few bacteria
compared to the colon. Bowel prep is critical for reducing bacterial load to
minimize infectious complications.
Question 3
An Ileal pouch anal anastomosis (IPAA), also referred to as the ileoanal
reservoir, is indicated for which of the following disease processes?
• A) Irritable bowel syndrome and Crohn's Disease
• B) Colorectal cancer and chronic ulcerative colitis
• C) Crohn's Disease and chronic ulcerative colitis
• D) Ulcerative colitis and familial adenomatous polyposis
Correct Answer: D - Ulcerative colitis and familial adenomatous polyposis
Rationale: IPAA (J-pouch) is indicated for patients with ulcerative colitis or
familial adenomatous polyposis (FAP) who require colectomy but want to
,preserve transanal defecation. It is contraindicated in Crohn's disease due to
high risk of recurrence and complications. IBS is a functional disorder not
requiring surgery.
Question 4
The preferred abdominal location for an ileostomy in the adult is the:
• A) Left lower quadrant (LLQ)
• B) Left upper quadrant (LUQ)
• C) Right lower quadrant (RLQ)
• D) Right upper quadrant (RUQ)
Correct Answer: C - Right lower quadrant (RLQ)
Rationale: The ileostomy is typically placed in the RLQ because the terminal
ileum naturally lies in this quadrant. This allows for a straight, tension-free
stoma. Colostomies are typically placed in the LLQ.
Question 5
A patient with a history of Crohn's disease is experiencing a recurrence. Which
symptom is the patient most likely experiencing?
• A) Obstructive abdominal pain
• B) Absence of perianal disease
• C) Bloody stools with proctitis
• D) Vomiting
Correct Answer: A - Obstructive abdominal pain
, Rationale: Crohn's disease is characterized by transmural inflammation that
leads to stricture formation and bowel obstruction. Obstructive abdominal
pain is a common presentation of Crohn's recurrence. Bloody stools with
proctitis are more characteristic of ulcerative colitis. Perianal disease (fistulas,
abscesses) is common in Crohn's, not absent.
Question 6
The patient with ulcerative colitis will commonly exhibit:
• A) Oral ulcerations
• B) Significant abdominal pain
• C) Superficial mucosal involvement
• D) Fistula formation
Correct Answer: C - Superficial mucosal involvement
Rationale: Ulcerative colitis is limited to the mucosal layer of the colon and
rectum. The inflammation is continuous and superficial, not transmural
(unlike Crohn's). Fistula formation is characteristic of Crohn's, not UC.
Significant abdominal pain is less common in UC than in Crohn's.
Question 7
Anorectal malformation in the neonate is also known as:
• A) Hirschsprung's disease
• B) Imperforate anus
• C) Turcot syndrome
• D) Volvulus
