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?
Correct Answer: B) Villi
Rationale: The villi are the finger-like projections on the small
bowel mucosa responsible for nutrient absorption. Lack of enteral
nutrition 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:
Correct Answer: A) Distal portion of the colon
Rationale: The bacterial count is highest in the distal colon due to
its role in waste storage and fermentation .
3. An Ileal pouch anal anastomosis (IPAA), also referred to as
the ileoanal reservoir, is indicated for which of the following
disease processes?
, Correct Answer: D) Ulcerative colitis and familial adenomatous
polyposis
Rationale: IPAA is the surgical treatment of choice for ulcerative
colitis and familial adenomatous polyposis (FAP), as both require
total colectomy. It is generally contraindicated for Crohn's disease
due to the risk of recurrence in the pouch .
4. The preferred abdominal location for an ileostomy in the
adult is the:
Correct Answer: C) RLQ (Right Lower Quadrant)
Rationale: The RLQ is the preferred location because the terminal
ileum naturally reaches this area, allowing for easier pouching and
better visibility for the patient. A colostomy is typically placed in
the left lower quadrant (LLQ) .
5. Gary is experiencing a recurrence of his Crohn's Disease.
Which of the following symptoms is Gary most likely
experiencing?
Correct Answer: B) Obstructive abdominal pain
Rationale: Crohn's disease is a transmural inflammation that can
lead to strictures and bowel obstructions, causing crampy or
obstructive abdominal pain. Bloody diarrhea is more characteristic
of ulcerative colitis .
6. Which of the following statements about Crohn's disease
and/or ulcerative colitis is true?
Correct Answer: D) Ulcerative colitis begins in the rectal area and
progresses backward toward the ileocecal valve
, Rationale: Ulcerative colitis is characterized by continuous
inflammation that begins in the rectum and extends proximally. It
is limited to the colon and affects only the mucosal and
submucosal layers. In contrast, Crohn's disease is a transmural,
patchy process that can affect any part of the GI tract .
7. A WOC nurse assesses a patient who is 12 hours post-
operative from an ileostomy creation. The stoma appears
dark purple and dusky, but remains moist. What is the most
appropriate immediate action by the nurse?
Correct Answer: C) Notify the surgical team immediately to
evaluate for compromised perfusion.
Rationale: A dark purple or dusky stoma indicates severe
ischemia due to compromised blood flow. This is a surgical
emergency requiring immediate evaluation to prevent stoma
necrosis. A healthy stoma should be bright red or pink and moist .
8. Which structural component serves as the primary
mechanism for maintaining continence in a patient with a
Kock continent ileostomy?
Correct Answer: A) A surgically constructed nipple valve from the
terminal ileum.
Rationale: The Kock pouch uses a nipple valve, created by
intussuscepting the ileum, which acts as a one-way valve to
prevent leakage of gas and stool until the reservoir is catheterized
for drainage .
9. A patient with a new ileostomy presents with a 24-hour
total output of 1,800 mL. Which clinical complication should
the WOC nurse prioritize for monitoring?
, Correct Answer: C) Dehydration, hypokalemia, and acute kidney
injury.
Rationale: Normal ileostomy output is 500-1,200 mL/day. Output
exceeding 1,500 mL is high-output and can rapidly lead to
dehydration, electrolyte loss (especially hypokalemia), and acute
kidney injury .
10. A patient who has been kept strictly NPO (nothing by
mouth) for seven days while on total parenteral nutrition
(TPN) is at high risk for which specific gastrointestinal
change?
Correct Answer: B) Atrophy of the small bowel mucosal villi.
Rationale: A lack of enteral feeding (NPO) leads to atrophy of the
small bowel villi. This is a primary reason for starting enteral
nutrition as soon as possible to maintain gut integrity .
11. An adult patient undergoes an abdominoperineal
resection (APR) for a malignancy located distal to the dentate
line. Which type of stoma should the nurse prepare the
patient for?
Correct Answer: C) Permanent sigmoid colostomy.
Rationale: An APR removes the rectum, anus, and sphincter
muscles. Because the natural route for stool is permanently
removed, a permanent colostomy (typically sigmoid) is required .
12. A patient returns to the clinic with severe, painful skin
erosion and bright red erythema that perfectly mirrors the
circular shape of the skin barrier opening. What is the primary
etiology of this condition?
atrophy of which of the following structures in the mucosal
surface of the small bowel?
