10. Complex Stoma Presentations and Complications
1. A patient with a newly formed end colostomy presents 48 hours postoperatively with a stoma
that appears dusky with a bluish-purple discoloration and lacks a capillary refill response. Which
clinical judgment is most appropriate?
A. Apply a warm compress to the stoma to improve local perfusion.
B. Request an immediate surgical consultation to assess for bowel ischemia.
C. Document the observation and continue monitoring for another 24 hours.
, D. Irrigate the stoma with sterile saline to check for patency.
Answer: B
Rationale: A dusky, cyanotic stoma with absent capillary refill indicates compromised blood
supply, which is a surgical emergency. Option A is dangerous as thermal application does not fix
necrosis. Option C delays critical intervention, risking bowel perforation, and Option D is
irrelevant to vascular integrity.
2. A patient with an ileostomy presents with a high-output volume of 2,500 mL/day. Which
electrolyte imbalance is the patient at greatest risk for, and what is the initial priority
intervention?
A. Hyperkalemia; administer potassium-sparing diuretics.
B. Hyponatremia; initiate oral rehydration solutions with sodium supplementation.
C. Hypercalcemia; restrict dietary calcium intake.
D. Metabolic alkalosis; administer IV sodium bicarbonate.
Answer: B
Rationale: High-output ileostomy results in significant loss of water and sodium, leading to
hyponatremia and volume depletion. Option A would exacerbate potential renal issues, Option C
is unrelated to typical ileostomy fluid loss, and Option D is incorrect as these patients typically
develop metabolic acidosis due to bicarbonate loss.
3. A patient with a permanent colostomy reports frequent leakage around the appliance flange,
leading to peristomal irritation. Upon assessment, you note a parastomal hernia. Which
intervention is most appropriate?
A. Instruct the patient to use a convex wafer with a heavy-duty ostomy belt.
B. Recommend a flexible, low-profile pouching system and a customized hernia support
garment.
C. Perform a surgical revision of the stoma site immediately.
D. Apply an absorbent paste around the stoma to fill the gap.
Answer: B
Rationale: A parastomal hernia alters the contour of the abdominal wall, making a rigid convex
wafer potentially cause more pressure and skin breakdown. A flexible system conforms to the
bulge, while a support garment provides necessary structural support. Options A and D do not
, address the underlying anatomical change, and C is not the first-line management for a
manageable hernia.
4. You are managing a patient with a continent ileostomy (Kock pouch). The patient reports
difficulty intubating the nipple valve. Which action should be taken first?
A. Administer a sedative to relax the patient.
B. Irrigate the pouch with warm saline using a soft catheter.
C. Instruct the patient to force the catheter into the valve.
D. Refer the patient for immediate surgical reconstruction.
Answer: B
Rationale: Difficulty intubating a continent ileostomy is often caused by debris or thick mucus
obstructing the valve. Irrigation with warm saline clears the obstruction gently. Option A is
unnecessary, C causes potential trauma to the delicate valve, and D is premature before
troubleshooting.
5. A patient with an ileostomy is diagnosed with Crohn’s disease. They present with painful,
ulcerated skin lesions surrounding the stoma. What is the most likely diagnosis?
A. Allergic contact dermatitis.
B. Pyoderma gangrenosum.
C. Candidiasis.
D. Stomal prolapse.
Answer: B
Rationale: Pyoderma gangrenosum is a known extraintestinal manifestation of Crohn's disease
that frequently presents around stoma sites. It is distinct from the other conditions because it
presents as painful, necrotic ulcers with violaceous borders. A, C, and D are incorrect because
they have different clinical morphologies (e.g., fungal rash, allergic red patch).
6. When selecting a skin barrier for a patient with a urostomy, which property is most critical to
prevent peristomal skin breakdown?
A. Maximum flexibility for active movement.
B. Extended wear time with high resistance to urine degradation.
, C. Minimal thickness to improve aesthetic appearance.
D. Use of hypoallergenic tape only.
Answer: B
Rationale: Urostomy effluent is acidic and contains urea, which can rapidly break down
standard skin barriers. A barrier must be resistant to these chemical properties to protect the
skin. Options A and C are secondary to the primary need for chemical protection, and D is
insufficient for preventing leakage.
7. A patient with a sigmoid colostomy wants to utilize irrigation for bowel management. Which of
the following is a contraindication?
A. Patient preference for once-daily evacuation.
B. The presence of a symptomatic parastomal hernia.
C. History of diverticulosis.
D. Well-defined, flush stoma.
Answer: B
Rationale: Irrigation involves filling the bowel with water to stimulate peristalsis; a parastomal
hernia poses a high risk of bowel entrapment or perforation during this process. Options A, C,
and D are generally acceptable conditions for irrigation, provided the patient is properly
trained.
8. Which nutritional advice is most accurate for a patient with a new ileostomy to prevent
obstruction?
A. Eliminate all fiber from the diet indefinitely.
B. Chew high-fiber foods thoroughly and maintain adequate fluid intake.
C. Consume only liquid supplements to ensure bowel rest.
D. Increase intake of raw nuts and popcorn immediately.
Answer: B
Rationale: Ileostomates can tolerate fiber if it is chewed well to reduce particle size, preventing
bolus obstruction. Option A is nutritionally unnecessary, C is impractical for long-term health,
and D is dangerous as raw nuts/popcorn are high-risk foods for obstruction.
