rationales 2026/2027 version/instant pdf
1. A healthy stoma should normally appear:
A. Pale and dry
B. Pink to red and moist
C. Black and firm
D. Blue and cool
Correct Answer: B. Pink to red and moist
Rationale: A healthy stoma is well perfused and should be pink/red, moist, and shiny.
2. Which stoma finding requires immediate notification of the healthcare
provider?
A. Mild edema immediately after surgery
B. Pink, moist stoma
C. Dusky, purple, or black stoma
D. Small amount of bleeding during cleaning
Correct Answer: C. Dusky, purple, or black stoma
Rationale: Dark discoloration may indicate impaired blood supply and possible ischemia or
necrosis.
3. The most appropriate solution for cleaning a stoma is:
A. Hydrogen peroxide
B. Alcohol
C. Warm water
D. Full-strength iodine
Correct Answer: C. Warm water
Rationale: Warm water gently cleans the stoma without damaging tissue or interfering with
appliance adhesion.
4. A newly created ileostomy usually produces:
A. Formed stool
B. Liquid to semiliquid output
C. Urine only
D. No output permanently
,Correct Answer: B. Liquid to semiliquid output
Rationale: The ileum has limited water absorption, so ileostomy output is usually liquid or
semiliquid.
5. Which ostomy has the greatest risk for fluid and electrolyte imbalance?
A. Sigmoid colostomy
B. Descending colostomy
C. Ileostomy
D. Transverse colostomy
Correct Answer: C. Ileostomy
Rationale: High-volume liquid output from an ileostomy can cause dehydration and electrolyte
loss.
6. The opening in the skin barrier should generally be:
A. Much larger than the stoma
B. Approximately 1/8 inch larger than the stoma
C. Completely closed over the stoma
D. At least 2 inches larger than the stoma
Correct Answer: B. Approximately 1/8 inch larger than the stoma
Rationale: A close fit protects peristomal skin while avoiding pressure on the stoma.
7. The main purpose of a skin barrier is to:
A. Stop stoma output
B. Protect peristomal skin
C. Increase stool production
D. Make the stoma smaller
Correct Answer: B. Protect peristomal skin
Rationale: The barrier protects skin from moisture, enzymes, and chemical irritation.
8. A patient with a new ileostomy is at greatest risk for:
A. Constipation only
B. Dehydration
C. Urinary retention
D. Hypothermia
Correct Answer: B. Dehydration
Rationale: High-volume liquid output can result in significant fluid loss.
9. Which finding may indicate dehydration in a patient with an ileostomy?
, A. Moist mucous membranes
B. Clear urine
C. Dizziness and decreased urine output
D. Increased skin turgor
Correct Answer: C. Dizziness and decreased urine output
Rationale: These are common signs of fluid volume deficit.
10. The best time to change an ostomy appliance is usually:
A. Immediately after a large meal
B. When output is minimal
C. During severe diarrhea
D. Only when the appliance falls off
Correct Answer: B. When output is minimal
Rationale: Changing the appliance when output is low improves cleanliness and adhesion.
11. A stoma should be measured:
A. Only once after surgery
B. Regularly, especially during the postoperative period
C. Only if it becomes painful
D. Only every five years
Correct Answer: B. Regularly, especially during the postoperative period
Rationale: Stoma size can change as postoperative edema decreases.
12. Which finding is expected during the early postoperative period?
A. Mild stoma edema
B. Black stoma
C. Severe abdominal rigidity
D. Complete absence of circulation
Correct Answer: A. Mild stoma edema
Rationale: Some edema is common after surgery and usually decreases over time.
13. A retracted stoma is one that:
A. Protrudes excessively
B. Is located below skin level
C. Has no opening
D. Is permanently swollen
