WEB WOC OSTOMY CARE FINAL EXAM: 250 PRACTICE QUESTIONS WITH
RATIONALES
QUESTIONS 1-50: OSTOMY ANATOMY AND SURGICAL TYPES
1. A patient presents with a stoma created from the terminal ileum. This type of
ostomy is best described as:
A. Colostomy
B. Urostomy
C. Ileostomy
D. Jejunostomy
Correct Answer: C
Rationale: An ileostomy is constructed from the ileum, the terminal portion of the small
intestine. A colostomy (A) uses the large intestine. A urostomy (B) typically uses a
segment of ileum to create a urinary conduit, but the stoma itself is called a urostomy. A
jejunostomy (D) uses the jejunum, which is higher in the small intestine and produces
very liquid, high-volume output .
2. The surgical creation of a stoma from the descending colon to divert fecal
material is called:
A. Transverse colostomy
B. Descending colostomy
C. Sigmoid colostomy
D. Ascending colostomy
Correct Answer: C
Rationale: A sigmoid colostomy is the most common type of colostomy, located in the
lower left quadrant and created from the descending colon or sigmoid colon. A
, Page 2 of 66
descending colostomy (B) is similar but specifically from the descending colon. A
transverse colostomy (A) is in the upper abdomen. An ascending colostomy (D) is in the
right upper quadrant.
3. A patient has a urinary diversion where a segment of the ileum is used to
transport urine to the abdominal surface. This is called:
A. Nephrostomy
B. Ileal conduit
C. Indiana pouch
D. Neobladder
Correct Answer: B
Rationale: An ileal conduit (also called a Bricker's procedure) uses a 10-12 cm segment
of ileum to create a passageway for urine from the ureters to the abdominal surface. A
nephrostomy (A) is a tube placed directly into the kidney. An Indiana pouch (C) is a
continent urinary diversion. A neobladder (D) is a surgically created bladder from bowel
tissue that connects to the urethra .
4. How much bowel length is required to create an ileal conduit?
A. 5-8 cm
B. 10-12 cm
C. 25-30 cm
D. 50-60 cm
Correct Answer: B
Rationale: An ileal conduit requires approximately 10-12 cm of ileum. This length is
sufficient to create a passageway for urine without significantly impacting nutrient
absorption. A neobladder (D) requires 50-60 cm of bowel. An Indiana pouch uses
approximately 20-30 cm of bowel .
5. Which of the following best describes an abdominoperineal resection (APR)?
A. Removal of the colon with rectal preservation
B. Removal of the rectum and anus with creation of a permanent end colostomy
C. Creation of a temporary loop ileostomy
D. Surgical removal of the large intestine only
Correct Answer: B
, Page 3 of 66
Rationale: An abdominoperineal resection (APR) involves removal of the rectum and
anus, resulting in a permanent end colostomy. The rectum is removed, and a perianal
surgical incision is closed. This procedure is commonly performed for low rectal
cancers. Hartmann's pouch (A) retains the rectum. Subtotal colectomy (D) removes
part of the colon .
6. Which surgical procedure creates a temporary colostomy or ileostomy while the
rectum is retained?
A. APR
B. Proctocolectomy
C. Hartmann's pouch
D. IPAA
Correct Answer: C
Rationale: Hartmann's pouch is a temporary colostomy or ileostomy where the distal
segment of the bowel (rectum) is retained and closed, forming a blind pouch. This is
often performed in emergency situations such as perforation or obstruction. The
colostomy can later be reversed when the patient's condition stabilizes .
7. What does IPAA stand for, and what is its purpose?
A. Ileal Pouch-Anal Anastomosis; creates a J-shaped reservoir for stool, eliminating the
need for a permanent ostomy
B. Intestinal Pouch-Anal Anastomosis; used for Crohn's disease patients
C. Ileal Procedure for Anal Anastomosis; used for ulcerative colitis
D. Internal Pouch Anal Anastomosis; creates a permanent stoma
Correct Answer: A
Rationale: IPAA (Ileal Pouch-Anal Anastomosis), also known as a J-pouch, creates an
internal reservoir from the ileum that is connected to the anus, eliminating the need for
a permanent ostomy. It is performed in stages: Stage 1 - temporary end ileostomy, Stage
2 - temporary loop ileostomy, Stage 3 - ileostomy takedown. IPAA is NOT recommended
for Crohn's disease patients due to high incidence of pouch failure .
8. The Kock pouch is best described as:
A. A permanent end ileostomy
B. A continent ileal reservoir with a nipple valve
, Page 4 of 66
C. A temporary loop colostomy
D. A urinary diversion with a stoma
Correct Answer: B
Rationale: The Kock pouch is a type of continent ileal reservoir created by making an
internal pouch with a portion of the ileum and placing a nipple valve flush with the
stoma. This allows the patient to self-intubate the pouch to drain stool, eliminating the
need for an external pouching system. It is a continent fecal diversion .
9. A patient diagnosed with ulcerative colitis that is unresponsive to medication
undergoes which surgical procedure?
A. Proctocolectomy with permanent end ileostomy
B. Subtotal colectomy with reanastomosis
C. Diverting loop ileostomy
D. Sigmoid colectomy
Correct Answer: A
Rationale: Proctocolectomy (surgical removal of the large intestine and rectum) with
permanent end ileostomy is considered curative for ulcerative colitis. UC always
appears in the rectum and occasionally in the right colon, making removal of the entire
colon and rectum necessary. Crohn's disease (A, B, C) is managed with bowel resection
and reanastomosis .
10. What is the guiding principle of surgical management for Crohn's disease?
A. Total proctocolectomy
B. Preservation of intestinal length and function
C. Permanent end ileostomy
D. Complete resection of all affected bowel
Correct Answer: B
Rationale: The guiding principle of surgical management for Crohn's disease is
preservation of intestinal length and function. Unlike ulcerative colitis, Crohn's disease
is not cured by surgery, and removing too much bowel can lead to short bowel
syndrome. Surgical interventions focus on relieving obstruction, treating perforation, or
managing hemorrhage while preserving as much intestine as possible .
