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 – Villi
Rationale: The villi are finger-like projections on the mucosal surface
of the small bowel responsible for nutrient absorption. Prolonged NPO
status (lack of enteral nutrition) leads to villous atrophy because the gut
mucosa requires luminal nutrients to maintain its structure and function.
The other structures are anatomical landmarks (Ligament of Treitz,
Ampulla of Vater, Sphincter of Oddi) and are not affected by NPO status
in the same way .
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 – Distal portion of the colon
Rationale: Bacterial concentration increases as you move distally
through the gastrointestinal tract. The colon, particularly the distal
portion, harbors the highest concentration of bacteria. Preoperative
bowel prep targets these bacteria to reduce the risk of infection and
anastomotic leaks. The small bowel has far fewer bacteria .
3. An Ileal pouch anal anastomosis (IPAA), 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 – Ulcerative colitis and familial
adenomatous polyposis
Rationale: IPAA is the surgical procedure of choice for patients with
ulcerative colitis or familial adenomatous polyposis (FAP) who require
total proctocolectomy. It allows the patient to avoid a permanent
ileostomy. Crohn's disease is generally a contraindication for IPAA due
to the risk of recurrence in the pouch. IBS does not require surgical
intervention .
4. The preferred abdominal location for an ileostomy in the adult is
the:
A. LLQ
B. LUQ
,C. RLQ
D. RUQ
Correct ,,,,Answer,,,,: C – RLQ (Right Lower Quadrant)
Rationale: The right lower quadrant is the preferred site for an
ileostomy because it allows the patient to see and access the stoma
easily, facilitates proper pouching, and is typically within the rectus
muscle, which helps prevent parastomal hernias. The terminal ileum
naturally reaches the RLQ .
5. Gary is experiencing a recurrence of his Crohn's Disease. Which
of the following symptoms is Gary most likely experiencing?
A. Bloody diarrhea
B. Obstructive abdominal pain
C. Absence of perianal disease
D. Rectal sparing with no symptoms
Correct ,,,,Answer,,,,: B – Obstructive abdominal pain
Rationale: Crohn's disease causes transmural inflammation that can lead
to strictures and bowel obstruction, resulting in crampy, obstructive
abdominal pain. Bloody diarrhea is more characteristic of ulcerative
colitis. Perianal disease is actually common in Crohn's disease. Pain is a
hallmark symptom of recurrence .
6. During a preoperative consultation for emergency ostomy
surgery, the two PRIMARY objectives for the WOC Nurse are
stoma site selection and:
A. Explanation of how to empty the pouch
B. Demonstration of ostomy equipment
C. Decrease patient's anxiety about the ostomy surgery
D. Identification of discharge plans
, Correct ,,,,Answer,,,,: C – Decrease patient's anxiety about the
ostomy surgery
Rationale: In emergency ostomy surgery, the patient has had little time
to psychologically prepare. The two primary objectives are stoma site
selection and decreasing patient anxiety. Technical teaching about
pouching equipment and discharge planning is secondary and can occur
postoperatively when the patient is more receptive .
7. When selecting an abdominal stoma site, evidence-based practice
states that the stoma should be located:
A. Lateral to the rectus muscle
B. Above the beltline
C. On the apex of the infraumbilical bulge
D. Near the umbilicus
Correct ,,,,Answer,,,,: C – On the apex of the infraumbilical bulge
Rationale: The stoma should be placed within the rectus muscle on the
apex of the infraumbilical bulge. This placement reduces the risk of
parastomal hernia, ensures the patient can see the stoma, and allows for
optimal pouching. Placing the stoma lateral to the rectus muscle
increases hernia risk. The stoma should be below the beltline, not
above .
8. You are selecting a stoma site pre-op for a patient having an
IPAA and temporary loop ileostomy. The patient has no abdominal
scars but a soft, slightly protruding abdomen. You palpate for the
rectus muscle, mark the RLQ, confirm the patient can see the site
while lying down, and cover the mark with a transparent dressing.
What step have you omitted?
A. To check the potential stoma site with the patient in a sitting and
standing position
B. To ask the patient if they prefer the right side or the left side
