SECTION 1: ASSESSMENT (12 Questions)
Questions 1-12
Question 1
A patient with familial adenomatous polyposis (FAP) is scheduled for a total proctocolectomy with an
ileal pouch-anal anastomosis (IPAA). During preoperative counseling, which information is MOST
critical for the ostomy nurse to emphasize regarding the temporary loop ileostomy?
A) The temporary stoma will be permanent if pouchitis develops
B) The stoma will be located on the right side of the abdomen
C) The stoma is temporary and will be reversed after the pouch heals
D) The stoma will require irrigation daily
Correct Answer: C
Rationale: With an IPAA, a temporary loop ileostomy is created to protect the pouch while it heals. The
patient must understand that the ileostomy is temporary and will be reversed once the pouch is healed,
typically after 8-12 weeks. This is essential for patient education and managing expectations .
Question 2
A patient who has been 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

QUESTIONS | NGN-ALIGNED | MULTIPLE-CHOICE | DETAILED RATIONALES |
100% CORRECT ANSWERS | COMPREHENSIVE REVIEW – GRADED A+
Correct Answer: B
Rationale: The villi of the small bowel are at risk for atrophy when a patient is NPO for extended periods.
Villi rely on enteral nutrition for maintenance, and lack of oral intake leads to villous atrophy. The
Ligament of Treitz, Ampulla of Vater, and Sphincter of Oddi are anatomical structures not directly
involved in mucosal surface atrophy .
Question 3
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) Terminal ileum
D) Jejunum
Correct Answer: A
Rationale: The distal portion of the colon contains the highest concentration of bacteria, with counts
reaching 10^11-10^12 CFU/mL. Bacterial counts increase progressively from the proximal to the distal
colon .
Question 4
During a stoma site marking assessment, which of the following is the MOST important consideration?
A) The patient's dominant hand
B) The patient's abdominal contours and clothing choices
C) The patient's age
D) The patient's occupation

QUESTIONS | NGN-ALIGNED | MULTIPLE-CHOICE | DETAILED RATIONALES |
100% CORRECT ANSWERS | COMPREHENSIVE REVIEW – GRADED A+
Correct Answer: B
Rationale: According to the COCN content outline, stoma site marking must consider abdominal
contours, clothing choices, pouching options, lifestyle, and surgical procedures. The site must be placed
within the rectus abdominis muscle to prevent parastomal herniation .
Question 5
Which of the following is a risk factor for peristomal complications?
A) Well-healed stoma
B) Flat abdomen
C) Stoma located within a skin fold or crease
D) Stoma with adequate protrusion
Correct Answer: C
Rationale: A stoma located within a skin fold or crease creates a pouching challenge and increases the risk
of peristomal skin complications. This leads to poor adherence of the pouching system and leakage of
effluent onto the skin .
Question 6
A patient with an ileostomy is experiencing high output. The nurse should assess for which of the
following?
A) Fluid and electrolyte imbalances
B) Increased appetite
C) Weight gain
D) Constipation
Correct Answer: A
