OSTOMY CARE EXAM (QUESTIONS 1–90)
SECTION 1: OSTOMY TYPES AND SURGICAL INDICATIONS
1. A patient with muscle-invasive bladder cancer is scheduled for surgery. Which
procedure would you expect them to have?
• A) Simple cystectomy
• B) Antegrade continence enema (ACE) procedure
• C) Ileal vesicostomy
• D) Radical cystectomy
Answer: D) Radical cystectomy
Rationale: Once bladder cancer invades the muscle, a radical cystectomy is
recommended for those healthy enough to undergo major surgery. A radical
cystectomy involves removing the bladder, surrounding fatty tissue, lymph glands,
and pelvic organs such as the prostate and seminal vesicles in men or uterus and
part of the vaginal wall in women . A simple cystectomy would not be appropriate
as it only removes the bladder. An ileal vesicostomy is performed for neurogenic
bladder dysfunction, and an ACE procedure is an antegrade colonic enema to help
the colon evacuate feces.
2. Which surgical procedure is the preferred treatment for a young person with
active ulcerative colitis?
, • A) Proctocolectomy with ileal pouch-anal anastomosis (IPAA)
• B) Subtotal colectomy with permanent colostomy
• C) Low anterior resection with temporary ileostomy
• D) Total colectomy with an ileoanal anastomosis
Answer: A) Proctocolectomy with ileal pouch-anal anastomosis (IPAA)
Rationale: Proctocolectomy with IPAA is the preferred treatment for ulcerative
colitis and allows the person to resume life without a permanent ostomy . A
subtotal colectomy with permanent colostomy would not be recommended as the
disease may recur in the remaining colon. Low anterior resection would only be
appropriate as an emergency treatment for toxic colitis. Total colectomy with
ileoanal anastomosis is no longer a treatment of choice due to the common
occurrence of fecal urgency and frequency.
3. A patient with rectal adenocarcinoma is having surgery and will have an
ostomy. They have been told that the stoma may be temporary or permanent
depending on the exact location of the tumor. Where would you mark this
patient for a stoma?
• A) Right lower quadrant of the abdomen
• B) Left lower quadrant of the abdomen
• C) Right and left lower quadrants of the abdomen
• D) All 4 quadrants of the abdomen
Answer: C) Right and left lower quadrants of the abdomen
Rationale: When performing a stoma site marking, the WOC-AP nurse should
consider possible surgical options. A patient with rectal adenocarcinoma is a
candidate for an abdominal perineal resection (permanent colostomy in the left
lower quadrant) or a low anterior resection (diverting loop ileostomy in the right
lower quadrant). Therefore, the WOC-AP nurse should mark two possible sites in
the right and left lower quadrants, and the surgeon would use the most
appropriate site based on the type of stoma constructed .
,4. A patient who had treatment for prostate cancer 10 years ago presents with a
several-month history of diarrhea and bright red blood from the rectum. A
colonoscopy revealed 2 very small polyps. Dietary changes have made no
difference in the frequency of diarrhea. What is the most likely diagnosis for this
patient?
• A) Neuroendocrine tumor of the small intestine
• B) Radiation enteritis
• C) Large and extensive hemorrhoids
• D) Irritable bowel syndrome
Answer: B) Radiation enteritis
Rationale: Radiation enteritis is a complication of radiation therapy used to treat
pelvic malignancies of organs such as the prostate. This condition can occur as
early as 2 weeks after treatment or as late as 30 years. Symptoms may include
nausea, vomiting, pain, diarrhea, urgency, bleeding, or fecal incontinence .
Hemorrhoids could cause bleeding but were not mentioned in the colonoscopy
results. Irritable bowel syndrome does not typically cause bleeding. A
neuroendocrine tumor of the small bowel is very rare.
5. Which of the following is a continent fecal diversion?
• A) Ileal conduit
• B) Ileal pouch-anal anastomosis (IPAA)
• C) End colostomy
• D) Loop ileostomy
Answer: B) Ileal pouch-anal anastomosis (IPAA)
Rationale: An IPAA is a continent fecal diversion that allows the patient to
maintain continence and avoid a permanent external ostomy. The WOCNCB
content outline differentiates continent fecal diversions (IPAA, Kock pouch) from
traditional ostomies .
, 6. A patient with neurogenic bowel and intractable fecal incontinence finds the
odor associated with this condition unacceptable. Which solution may be the
best option for improving their quality of life?
• A) Odor-reducing skin cleansers
• B) Reusable padded underwear
• C) Diverting colostomy
• D) Dietary measures to improve stool consistency
Answer: C) Diverting colostomy
Rationale: Bypassing the sphincter with a diverting colostomy will allow the
patient to wear an odor-proof pouch over the stoma and relieve the
embarrassment and anxiety of unpredictable bowel movements and the need for
immediate cleansing and clothing changes . Odor-reducing skin cleansers and
reusable padded underwear still leave the patient with the problem of odor at
each occurrence. Dietary measures do not correct the underlying neurological
cause of the incontinence.
7. Which type of stoma typically has the highest complication rate?
• A) End colostomy
• B) End ileostomy
• C) Loop ileostomy
• D) Loop colostomy
Answer: C) Loop ileostomy
Rationale: According to clinical literature, loop ileostomies have the highest
complication rates, while end ileostomies and end colostomies have the lowest
complication rates .
8. A patient with a history of diverticulitis is scheduled for a Hartmann's
procedure. What type of stoma will this patient likely have?
• A) Temporary loop ileostomy
