100 Practice Questions for the WEB WOC Ostomy
Care Final Exam
Section 1: Anatomy, Physiology & Pathology
(Questions 1-15)
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.
☑VERIFIED ANSWER: B. Villi.
Rationale: The villi are the small, finger-like
projections on the mucosal surface of the small
,intestine responsible for nutrient absorption. When
a patient is NPO (nothing by mouth), the lack of
luminal nutrients can lead to atrophy of these
structures, reducing the absorptive surface area.
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.
☑VERIFIED ANSWER: A. Distal portion of the colon.
Rationale: The bacterial count increases
progressively along the gastrointestinal tract, with
the highest concentration found in the distal colon.
This is due to the slower transit time and more
favorable environment for bacterial growth in this
area.
,3. 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
☑VERIFIED ANSWER: B. Ulcerative colitis and
familial adenomatous polyposis
Rationale: IPAA, or a J-pouch, is the surgical
procedure of choice for patients requiring a total
proctocolectomy. It is primarily indicated for
ulcerative colitis and familial adenomatous
polyposis. Crohn’s disease is generally a
contraindication due to the risk of recurrence in the
pouch .
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
☑VERIFIED ANSWER: B. Begins in the rectum and
extends proximally
Rationale: Ulcerative colitis is characterized by
continuous inflammation that starts in the rectum
and extends proximally through the colon. It is
limited to the mucosal and submucosal layers and
does not have "skip lesions," which are a hallmark
of Crohn's disease .
5. A key feature of Crohn’s disease is:
• A. Continuous lesion pattern
• B. Skip lesions
• C. Rectal-only involvement
• D. Superficial inflammation
☑VERIFIED ANSWER: B. Skip lesions
Rationale: Crohn’s disease is a transmural
