1. A 58-year-old male post-abdominal perineal resection for rectal cancer presents with a
newly formed end colostomy. On postoperative day two, the nurse assesses the stoma and
notes it is dark purple-black, dry, and cool to the touch. What is the immediate priority
action?
A. Apply a hydrocolloid barrier powder and a loose pouching system
B. Document the finding as a normal expected ischemic transition phase
C. Notify the surgeon immediately for potential surgical revision
D. Gently dilate the stoma lumen with a lubricated gloved finger
Notify the surgeon immediately for potential surgical revision because a dark purple-black,
dry, and cool stoma indicates acute ischemia and necrosis, which requires urgent surgical
intervention.
2. When planning pouching system selection for an obese patient with a deep skin fold and
a flush ileostomy located directly within a deep crease, which appliance modification is
most appropriate to prevent leakage?
A. Use a flat, transparent one-piece pouching system with micro-skin barriers
B. Utilize a convex pouching system combined with appropriate barrier ring seals
C. Apply tincture of benzoin across the entire crease before pouch application
D. Recommend immediate surgical relocation of the stoma to an upper quadrant
Utilize a convex pouching system combined with appropriate barrier ring seals because
convexity applies direct peristomal pressure to flatten surrounding creases and secure a proper
seal for a flush stoma.
3. A patient with a loop transverse colostomy for diverticular perforation calls the
outpatient clinic reporting a moderate amount of serosanguineous drainage and mild
edema of the stoma. What is the best initial nursing response?
A. Reassure the patient that mild edema and minor serosanguineous drainage are normal
postoperative findings
B. Instruct the patient to report immediately to the emergency department for bowel
strangulation
C. Tell the patient to remove the pouching system and apply direct pressure with sterile gauze
D. Schedule an immediate surgical consultation to evaluate for stoma necrosis
,Reassure the patient that mild edema and minor serosanguineous drainage are normal
postoperative findings because the stoma typically exhibits transient swelling and minor
oozing during the early recovery period.
4. Which of the following anatomic landmarks is considered the gold standard when pre-
marking a standard abdominal stoma site for an elective low anterior resection?
A. Directly over the umbilicus to maximize cosmetic symmetry
B. Within the rectus abdominis muscle away from scars, skin folds, and bony prominences
C. Along the beltline directly adjacent to the anterior superior iliac spine
D. In the left lower quadrant precisely over previous surgical incision lines
Within the rectus abdominis muscle away from scars, skin folds, and bony prominences
because siting the stoma through this muscle provides structural support and minimizes
herniation risks.
5. A patient with a urostomy complains of persistent, foul-smelling urine and dark brown
sediment collecting in the bottom of the nighttime drainage bag. What diagnostic
evaluation should be performed first?
A. Immediate 24-hour creatinine clearance testing
B. Urine culture and sensitivity via catheterization of the stoma conduit
C. Clean catch midstream urine sample collection
D. Urine sample obtained directly from the newly applied pouch drain valve
Urine sample obtained directly from the newly applied pouch drain valve because collecting
urine straight from a clean pouch outlet avoids stoma trauma while allowing prompt
assessment for urinary tract infection.
6. Which skin barrier ingredient is primarily responsible for absorbing moisture and
maintaining adhesion in an acidic or alkaline ostomy environment?
A. Petrolatum jelly base
B. Hydrocolloid polymers such as pectin and gelatin
C. Pure silicone elastomer gel
D. Synthetic acrylic adhesive resin
Hydrocolloid polymers such as pectin and gelatin because these hydrophilic components
absorb moisture from stomal output while maintaining a secure seal and protecting the skin.
7. A patient with an ileostomy exhibits high-output volume exceeding 1,500 mL per day,
accompanied by dry mucous membranes, lethargy, and elevated serum creatinine. Which
pathophysiological mechanism explains this presentation?
A. Hypersecretion of gastric acid secondary to parietal cell hyperplasia
, B. Loss of absorptive surface area and rapid transit time preventing fluid and electrolyte
reabsorption
C. Bacterial overgrowth in the distal jejunum causing osmotic diarrhea
D. Primary renal tubular acidosis induced by chronic loop diuretic administration
Loss of absorptive surface area and rapid transit time preventing fluid and electrolyte
reabsorption because an ileostomy bypasses the colon where the vast majority of water and
sodium reclamation occurs.
8. When educating a newly ostomized patient regarding dietary management, which
instruction is most crucial for preventing mechanical bowel obstruction?
A. Completely avoid all forms of dietary fiber for the remainder of your life
B. Thoroughly chew high-fiber foods such as celery, nuts, and popcorn, and maintain
adequate hydration
C. Limit total daily fluid intake to less than 1,000 mL to minimize pouch emptying frequency
D. Ingest high-sugar beverages to stimulate rapid peristalsis and bowel evacuation
Thoroughly chew high-fiber foods such as celery, nuts, and popcorn, and maintain adequate
hydration because poorly chewed fibrous foods can form a bolus and obstruct the stoma
lumen.
9. A patient presents with a severe peristomal moisture-associated skin damage (MAMI)
rash characterized by weeping, eroded skin beneath the pouch adhesive. What is the
immediate treatment approach?
A. Apply alcohol-based skin prep wipes to dry the moist lesion completely
B. Perform crusting technique using hydrocolloid powder and a skin sealant, then fit an
extended-wear barrier
C. Leave the area completely open to air without any pouching system until total healing occurs
D. Apply thick layers of zinc oxide ointment directly under the standard pouch adhesive
Perform crusting technique using hydrocolloid powder and a skin sealant, then fit an
extended-wear barrier because this protects denuded skin, absorbs exudate, and restores a dry
surface for adhesive bonding.
10. An ostomy nurse is evaluating a patient with a peristomal hernia. Which clinical sign
most accurately distinguishes a reducible hernia from an incarcerated hernia?
A. The presence of severe abdominal pain, nausea, and discoloration of the stoma mucosa
B. The ability to gently push the bulging mass back into the peritoneal cavity while the
patient is lying supine
C. The observation of high-pitched bowel sounds directly over the peristomal bulge
D. An acute elevation in white blood cell count and systemic fever
