WEB WOC OSTOMY CARE FINAL EXAM
QUESTIONS AND ANSWERS (VERIFIED
ANSWERS GRADED A+) LATEST UPDATE
Question 1: A patient with a new ileostomy reports output of 1800 mL over the
past 12 hours, along with dizziness and muscle cramps. The most immediate
concern is:
A) Bowel obstruction
B) Dehydration and electrolyte imbalance
C) Normal postoperative adaptation
D) Infection at the stoma site
*Rationale:- High-output ileostomy (>1200 mL/day) can lead to dehydration,
hyponatremia, hypokalemia, and acute kidney injury. Immediate assessment of
fluid status and electrolyte replacement is critical.*
Question 2: Which of the following peristomal complications is most common in
the first 30 days after ostomy surgery?
A) Peristomal hernia
B) Moist desquamation (irritant dermatitis)
C) Pyoderma gangrenosum
D) Stomal stenosis
Rationale:- Irritant dermatitis from leakage of effluent is the most common early
complication. Proper pouching fit and skin barrier are essential for prevention.
Question 3: A patient with a colostomy reports that the stool has become
increasingly thick and difficult to expel from the pouch. Which dietary
modification is most appropriate?
A) Increase intake of cheese and bananas
B) Increase fluid intake and add prune juice
C) Decrease fiber completely
D) Avoid all fruits and vegetables
,Rationale:- Constipation in colostomy can be managed with increased fluids,
prune juice, and appropriate fiber. Bananas and cheese may worsen constipation.
Question 4: A patient presents with a stoma that is dusky purple, with no bleeding
upon gentle touch, and no output for 6 hours. This indicates:
A) Normal healing
B) Venous ischemia or necrosis requiring immediate surgical evaluation
C) Mucosal irritation from adhesive
D) Benign hyperpigmentation
Rationale:- A dusky or purple stoma suggests compromised blood supply (venous
congestion or ischemia). Lack of output and non-bleeding are concerning signs;
emergent notification of surgeon is required.
Question 5: Which medication is most likely to cause an ileostomy to produce
very thick, pasty output?
A) Metoclopramide
B) Loperamide
C) Magnesium hydroxide
D) Senna
Rationale:- Loperamide is an antidiarrheal that slows intestinal transit and
thickens effluent. It is used to manage high-output ileostomy but can cause thick
output if overused.
Question 6: A patient with a urostomy (ileal conduit) notices mucus strands in the
urine. This is:
A) A sign of urinary tract infection
B) A normal finding because the intestinal segment produces mucus
C) Indicative of conduit stones
D) A sign of pouch leakage
Rationale:- The ileal conduit is lined with intestinal mucosa that secretes mucus.
Mucus in the urine is normal and expected, not a sign of infection.
, Question 7: Which of the following is the most appropriate pouching system for a
patient with a flush stoma that is located within a deep skin fold?
A) Flat barrier with no convexity
B) Convex barrier or convex insert
C) Two-piece system without tape border
D) Pediatric-sized pouch
Rationale:- Convexity helps to “push in” the peristomal skin, bringing a flush or
retracted stoma into the pouching field to prevent leakage. Deep folds also benefit
from convexity.
Question 8: The patient who is 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
Rationale:- Prolonged NPO status leads to disuse atrophy of the intestinal villi
due to lack of luminal nutrients, which can impair absorption.
Question 9: 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) Distal portion of the small bowel
D) Proximal portion of the small bowel
Rationale:- Bacterial concentration increases progressively from the small bowel
to the distal colon, which has the highest load of anaerobic bacteria.
Question 10: An Ileal pouch anal anastomosis (IPAA) which is also referred to as
the ileoanal reservoir is indicated for which of the following disease processes?
A) Irritable bowel syndrome and Crohn's disease
B) Colorectal cancer and chronic ulcerative colitis
