SECTION ONE: QUESTIONS 1-100
Which anatomical structure is most commonly associated with the formation of an end colostomy?
A. Ascending colon
B. Transverse colon
C. Descending or sigmoid colon
D. Ileum
🟢 C. Descending or sigmoid colon
🔴 RATIONALE: An end colostomy is most frequently created in the descending or sigmoid colon,
typically following a surgical procedure like an abdominoperineal resection.
A patient presents with a retracted stoma. What is the most appropriate initial nursing intervention?
A. Change to a flat barrier
B. Utilize a convex appliance system
C. Refer for immediate revision surgery
D. Apply a skin barrier paste to the entire abdomen
🟢 B. Utilize a convex appliance system
🔴 RATIONALE: Convexity is used to push the peristomal skin away from the stoma, helping to
overcome retraction and promote drainage into the pouch.
Which of the following is the most important factor in preventing peristomal skin complications?
A. Using a skin barrier with high alcohol content
B. Proper measurement and fit of the skin barrier
C. Applying barrier powder at every pouch change
D. Scrubbing the peristomal skin vigorously with soap
🟢 B. Proper measurement and fit of the skin barrier
,🔴 RATIONALE: Accurate sizing and proper fit of the appliance are the primary defenses against
effluent leakage, which is the leading cause of peristomal skin irritation.
A patient with an ileostomy complains of high output. Which electrolyte imbalance is most
concerning?
A. Hypercalcemia
B. Hyponatremia and hypokalemia
C. Hyperglycemia
D. Hypocalcemia
🟢 B. Hyponatremia and hypokalemia
🔴 RATIONALE: Ileostomy effluent is rich in sodium and potassium; high output can rapidly lead to
significant electrolyte depletion and dehydration.
What is the purpose of the stoma rod or bridge used post-operatively?
A. To prevent stenosis of the stoma
B. To support the weight of the pouch
C. To prevent the stoma from retracting into the peritoneal cavity
D. To assist in measuring the stoma
🟢 C. To prevent the stoma from retracting into the peritoneal cavity
🔴 RATIONALE: The bridge or rod is placed under the stoma loop immediately post-op to prevent
the loop from retracting until the bowel has adhered to the abdominal wall.
Which type of stoma typically produces the most liquid and corrosive effluent?
A. Sigmoid colostomy
B. Ascending colostomy
C. Ileostomy
D. Transverse colostomy
,🟢 C. Ileostomy
🔴 RATIONALE: Because the ileostomy is located in the small intestine before significant water
absorption occurs in the colon, the output is liquid and contains digestive enzymes.
Which of the following best describes the normal appearance of a healthy mature stoma?
A. Pale, dry, and cool
B. Dark, dusky, and firm
C. Beefy red, moist, and shiny
D. Prolapsed and edematous
🟢 C. Beefy red, moist, and shiny
🔴 RATIONALE: A healthy, viable stoma should be moist, shiny, and bright pink or red, similar to
the mucosa of the mouth.
When assessing a stoma, you note a purple-black discoloration. What is the priority action?
A. Document the finding and reassess in 4 hours
B. Apply a warm compress
C. Immediately notify the surgeon
D. Clean the stoma with alcohol
🟢 C. Immediately notify the surgeon
🔴 RATIONALE: A dark or purple-black stoma indicates ischemia or necrosis, which is a surgical
emergency requiring immediate intervention.
Which barrier accessory is best for filling in irregular folds around the stoma?
A. Barrier strips
B. Skin barrier paste
C. Waterproof tape
D. Gauze pads
, 🟢 B. Skin barrier paste
🔴 RATIONALE: Skin barrier paste is designed to fill in gaps and crevices around the stoma to
create a secure, leak-proof seal.
What is the primary function of a stoma belt?
A. To hold the pouch in place permanently
B. To increase convexity and ensure barrier adhesion
C. To prevent the development of a parastomal hernia
D. To replace the need for skin barrier adhesive
🟢 B. To increase convexity and ensure barrier adhesion
🔴 RATIONALE: Stoma belts provide pressure that enhances the convexity of an appliance,
assisting in a better seal for retracted or difficult stomas.
A patient with an ileostomy asks about diet. Which food should they avoid to prevent blockage?
A. Applesauce
B. White rice
C. Popcorn and nuts
D. Cooked carrots
🟢 C. Popcorn and nuts
🔴 RATIONALE: High-fiber, undigestible foods like nuts, popcorn, and raw vegetables can cause a
mechanical obstruction in a small-bore ileostomy.
Which of the following is a common symptom of a parastomal hernia?
A. Sharp, stabbing pain in the abdomen
B. A bulge around the stoma
C. Sudden cessation of output
D. Change in stoma color
