WEB WOC OSTOMY CARE Final Exam
Newest Exam Preparation With Complete Questions
1. What is the primary function of the large intestine?
A) Absorption of nutrients
B) Absorption of water and electrolytes
C) Production of digestive enzymes
D) Secretion of bile
Correct Answer: B) Absorption of water and electrolytes
Rationale: The large intestine's main function is to absorb water and electrolytes from the
remaining indigestible food matter, forming solid stool. While some nutrient absorption occurs,
it is not the primary function. Digestive enzymes are produced in the pancreas and small
intestine, and bile is produced by the liver.
2. Which layer of the gastrointestinal tract is responsible for peristalsis?
A) Mucosa
B) Submucosa
C) Muscularis externa
D) Serosa
Correct Answer: C) Muscularis externa
Rationale: The muscularis externa contains circular and longitudinal smooth muscle layers
responsible for peristaltic movements that propel contents through the digestive tract. The
mucosa is the innermost layer involved in absorption and secretion. The submucosa contains
blood vessels and nerves. The serosa is the outermost protective layer.
3. An ostomy is defined as:
A) Surgical removal of a diseased organ
B) Surgical creation of an opening from an internal organ to the body surface
C) Inflammation of the intestinal tract
D) A type of digestive disorder
Correct Answer: B) Surgical creation of an opening from an internal organ to the body surface
Rationale: An ostomy is a surgical procedure that creates an opening (stoma) from an internal
organ to the exterior of the body for the purpose of eliminating waste or providing nutrition.
Surgical removal of an organ is a resection. Inflammation is a disease process, not a surgical
creation.
4. A stoma is best described as:
A) The surgical procedure itself
B) The artificial opening created during surgery
,C) The pouch system used to collect effluent
D) The skin around the ostomy
Correct Answer: B) The artificial opening created during surgery
Rationale: A stoma is the actual opening created during ostomy surgery, typically made from a
portion of the intestine brought to the abdominal surface. The procedure is the ostomy surgery,
the pouch is the collection device, and the skin around the stoma is the peristomal skin.
5. Which type of ostomy involves the ileum being brought to the abdominal surface?
A) Colostomy
B) Ileostomy
C) Urostomy
D) Gastrostomy
Correct Answer: B) Ileostomy
Rationale: An ileostomy involves bringing the ileum (the final portion of the small intestine) to
the abdominal surface. A colostomy involves the colon, a urostomy involves the urinary system,
and a gastrostomy involves the stomach.
6. A colostomy is formed from which part of the digestive system?
A) Small intestine
B) Stomach
C) Large intestine (colon)
D) Esophagus
Correct Answer: C) Large intestine (colon)
Rationale: A colostomy is created from a portion of the colon (large intestine). The small
intestine creates an ileostomy. The stomach creates a gastrostomy. The esophagus is not
typically used to create an ostomy.
7. A urostomy is created to divert:
A) Feces
B) Gas
C) Urine
D) Bile
Correct Answer: C) Urine
Rationale: A urostomy is a urinary diversion that redirects urine from the kidneys to the outside
of the body, bypassing the bladder. Feces are diverted with colostomies or ileostomies. Gas and
bile are not the primary outputs of a urostomy.
8. Which ostomy type typically produces the most liquid effluent?
A) Descending colostomy
B) Sigmoid colostomy
,C) Transverse colostomy
D) Ileostomy
Correct Answer: D) Ileostomy
Rationale: An ileostomy produces the most liquid effluent because the small intestine absorbs
less water than the colon. The more distal the colostomy (descending, sigmoid), the more
formed the stool becomes as more water is absorbed.
9. A temporary loop ostomy is characterized by:
A) Both ends of the bowel brought out separately
B) A single stoma with two openings
C) The stoma being flush with the skin
D) The stoma being located in the upper abdomen
Correct Answer: B) A single stoma with one opening
Rationale: A loop ostomy creates a single stoma with both the proximal (functional) and distal
(non-functional) ends of the bowel opening through the same stoma. There are two openings
within the stoma. The other options describe other types of ostomies or characteristics.
10. An end ostomy is created when:
A) The bowel is not divided
B) The distal bowel is removed and the proximal end is brought out
C) Both ends are brought out through separate openings
D) The stoma is temporary
Correct Answer: B) The distal bowel is removed and the proximal end is brought out
Rationale: An end ostomy is formed when the distal portion of the bowel is removed (resected)
and the proximal (functional) end is brought to the abdominal surface to create a stoma. This is
typically a permanent ostomy.
11. A double-barrel ostomy consists of:
A) One stoma with two openings
B) Two separate stomas
C) A stoma that is flush with the skin
D) A stoma that is prolapsed
Correct Answer: B) Two separate stomas
Rationale: A double-barrel ostomy creates two separate stomas: the proximal stoma
(functional) and the distal stoma (non-functional, mucous fistula). A loop ostomy has one stoma
with two openings.
12. A mucous fistula is:
A) The functional part of the ostomy
B) The non-functional part of the ostomy that secretes mucus
, C) The pouch placed over the stoma
D) A type of infection
Correct Answer: B) The non-functional part of the ostomy that secretes mucus
Rationale: A mucous fistula is the distal, non-functioning segment of bowel that is brought to
the skin surface. It continues to secrete mucus (as normal intestinal tissue does), which is
drained. The functional part is the proximal stoma.
13. Which condition is a common indication for a colostomy?
A) Ulcerative colitis
B) Bladder cancer
C) Colorectal cancer
D) Crohn's disease of the small intestine
Correct Answer: C) Colorectal cancer
Rationale: Colorectal cancer is a common indication for a colostomy. Ulcerative colitis and
Crohn's disease affecting the small intestine are more frequently indications for an ileostomy.
Bladder cancer is an indication for a urostomy.
14. A common indication for an ileostomy includes:
A) Diverticulitis
B) Familial adenomatous polyposis (FAP)
C) Bladder cancer
D) Rectal cancer
Correct Answer: B) Familial adenomatous polyposis (FAP)
Rationale: FAP is a genetic condition causing numerous polyps in the colon and rectum, often
requiring a total proctocolectomy with a permanent ileostomy. Diverticulitis is often treated
with a colostomy. Bladder cancer leads to a urostomy. Rectal cancer may lead to a colostomy.
15. A common indication for a urostomy is:
A) Crohn's disease
B) Ulcerative colitis
C) Bladder cancer
D) Diverticulitis
Correct Answer: C) Bladder cancer
Rationale: Bladder cancer is the most common indication for a urostomy when the bladder must
be removed (cystectomy). Crohn's disease and ulcerative colitis are indications for intestinal
ostomies. Diverticulitis may require a colostomy.
16. The ideal stoma should be:
A) Flat and flush with the skin
B) Protruding 1-2 cm from the abdomen
