OSTOMY Care Practice Test Latest 2026-2027 with a
Review of 400 Practice Questions and Correct
Answers/ WEB WOC Ostomy Care Practice exam
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
Rationale: The villi are finger-like projections that increase surface area for
absorption; lack of enteral stimulation leads to villous atrophy.
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
Rationale: The distal colon harbors the highest concentration of bacteria due to
slower transit and fermentation.
3. An Ileal pouch anal anastomosis (IPAA) which is 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
Rationale: IPAA is the procedure of choice for ulcerative colitis and FAP when
the rectum is removed but the anal sphincter is preserved.
4. The preferred abdominal location for an ileostomy in the adult is the:
A) LLQ
B) LUQ
C) RLQ
D) RUQ
Correct Answer: C
Rationale: The right lower quadrant is the preferred site for an ileostomy because
it aligns with the natural path of the terminal ileum.
5. Gary is experiencing a recurrence of his Crohn's Disease. Which of the
following symptoms is Gary most likely experiencing?
A) Obstructive abdominal pain
B) Absence of perianal disease
C) Bloody stools with proctitis
D) Vomiting
Correct Answer: A
Rationale: Crohn's disease often causes strictures and obstructive symptoms due
to transmural inflammation.
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
Rationale: Ulcerative colitis is limited to the superficial mucosa of the colon and
rectum.
,7. When you read in the postoperative surgical report that the stoma was primarily
matured, you can expect which of the following?
A) The stoma will be opened at the bedside with electrocautery
B) The stoma has been present for at least 3 months
C) The stoma is ready for sutures at the mucocutaneous junction to be removed
D) The bowel was everted and sutured to the dermal surface during surgery
Correct Answer: D
Rationale: Primary maturation means the stoma is created and sutured in place
during the initial surgery.
8. Which of the following groups of medications is used in the medical
management of Crohn's disease?
A) Corticosteroids and immune suppressants
B) Anticholinergics and anti-emetics
C) Antidepressants and antibiotics
D) Immune suppressants and antidepressants
Correct Answer: A
Rationale: Corticosteroids and immunosuppressants (e.g., azathioprine, biologics)
are mainstays of Crohn's management.
9. Which of the following statements about Crohn's disease and/or ulcerative
colitis is true?
A) Both Crohn's Disease and ulcerative colitis are characterized by patchy mucosal
involvement and skip lesions
B) Crohn's Disease is limited to the colon and rectum
C) Ulcerative colitis is characterized by transmural involvement of the bowel wall
D) Ulcerative colitis begins in the rectal area and progresses backward toward the
ileocecal valve
Correct Answer: D
Rationale: Ulcerative colitis typically starts in the rectum and extends proximally
(continuous involvement).
, 10. You are consulted to see a patient who has just been diagnosed with low rectal
cancer located distal to the dentate line. You will prepare teaching materials to
cover content areas related to which of the following surgical procedures?
A) Low anterior resection (LAR)
B) Abdominoperineal resection (APR)
C) Total proctocolectomy (TPC)
D) Ileal Pouch Anal Anastomosis (IPAA or IAR)
Correct Answer: B
Rationale: Cancer below the dentate line requires APR, which removes the rectum
and anus, resulting in a permanent colostomy.
11. Pneumatosis is a radiologic finding associated with:
A) Hirschsprung's disease
B) Gut Malrotation
C) Diverticulitis
D) Necrotizing Enterocolitis (NEC)
Correct Answer: D
Rationale: Pneumatosis (air in the bowel wall) is a hallmark of NEC in neonates.
12. When preparing a 35-year-old male for colon resection with a temporary
ileostomy due to refractory Crohn's disease, he asks about sexual function after
surgery. You explain that this procedure involves:
A) Removal of the rectum only
B) Moderate incidence of premature ejaculation
C) Do not anticipate any sexual dysfunction
D) High incidence of erectile dysfunction
Correct Answer: C
Rationale: Resection of the colon alone (without pelvic dissection) does not
typically affect sexual function.
13. You receive a referral for a patient scheduled for an abdominoperineal
resection. Prior to reviewing the chart and interviewing the patient you can
anticipate his diagnosis to be:
