Question 1: Which type of ostomy is created from the small intestine and typically
produces liquid to semi-liquid effluent?
A. Sigmoid colostomy
B. Descending colostomy
C. Ileostomy
D. Transverse colostomy
CORRECT ANSWER: C. Ileostomy
Rationale: An ileostomy is surgically created from the ileum of the small intestine.
Because the effluent has not passed through the colon for water absorption, it is
typically liquid to semi-liquid and contains digestive enzymes that can be irritating to
peristomal skin. Understanding effluent characteristics is essential for appropriate
pouch selection and skin protection strategies.
Question 2: What is the primary purpose of measuring the stoma during each
pouch change in the early postoperative period?
A. To document stoma color for the medical record
B. To ensure the skin barrier opening is sized correctly to prevent skin exposure
C. To assess patient pain tolerance during care
D. To determine the brand of pouching system to use
CORRECT ANSWER: B. To ensure the skin barrier opening is sized correctly to
prevent skin exposure
Rationale: Stomas typically edematous immediately postoperatively and gradually
reduce in size over 6-8 weeks. Measuring the stoma at each pouch change ensures the
skin barrier opening is cut to fit within 1/8 inch of the stoma base, minimizing exposure
of peristomal skin to effluent while avoiding constriction that could impair circulation.
Question 3: Which peristomal skin complication is characterized by well-
demarcated, bright red, moist skin with satellite lesions?
A. Irritant contact dermatitis
B. Allergic contact dermatitis
C. Candidiasis
D. Psoriasis
CORRECT ANSWER: C. Candidiasis
Rationale: Candidiasis presents as bright red, moist skin with satellite lesions and is
caused by fungal overgrowth, often due to moisture trapped under the skin barrier or
antibiotic use. Differentiating this from irritant dermatitis (which follows effluent
,exposure patterns) is critical, as treatment requires antifungal powder rather than just
improved barrier protection.
Question 4: When educating a patient with a new ileostomy about fluid
management, which statement indicates understanding?
A. "I should limit fluids to 1 liter per day to reduce output."
B. "I need to drink at least 2-3 liters of fluid daily to prevent dehydration."
C. "I can replace electrolyte losses with sugary sports drinks exclusively."
D. "I should avoid all fluids 2 hours before bedtime."
CORRECT ANSWER: B. "I need to drink at least 2-3 liters of fluid daily to prevent
dehydration."
Rationale: Ileostomy output is high in fluid and electrolytes. Patients require increased
fluid intake (typically 2-3 liters/day) to prevent dehydration and electrolyte imbalances.
Education should emphasize water, oral rehydration solutions, and monitoring for signs
of dehydration (e.g., dark urine, dizziness), while cautioning against excessive sugary or
caffeinated beverages that may increase output.
Question 5: Which stoma assessment finding requires immediate notification of
the healthcare provider?
A. Stoma appears moist and beefy red
B. Stoma is slightly edematous on postoperative day 2
C. Stoma appears dark purple or black
D. Small amount of bleeding when cleaning the stoma
CORRECT ANSWER: C. Stoma appears dark purple or black
Rationale: A healthy stoma is moist and beefy red, indicating adequate blood supply.
Dark purple or black discoloration suggests ischemia or necrosis due to compromised
blood flow, which is a surgical emergency requiring immediate evaluation. Minor
bleeding during cleaning is expected due to the vascularity of the stoma mucosa.
Question 6: What is the recommended technique for removing a two-piece
pouching system to minimize skin trauma?
A. Pull the pouch straight away from the skin quickly
B. Use adhesive remover wipes while supporting the skin and gently lifting the flange
C. Soak the entire area in warm water for 10 minutes before removal
D. Cut the barrier into small pieces before removal
CORRECT ANSWER: B. Use adhesive remover wipes while supporting the skin and
gently lifting the flange
Rationale: Using adhesive remover wipes while supporting the peristomal skin and
gently lifting the flange from top to bottom reduces mechanical trauma, pain, and risk of
skin stripping. This technique preserves skin integrity, which is essential for maintaining
barrier adhesion and preventing complications.
,Question 7: Which patient statement indicates a need for further teaching
regarding ostomy appliance emptying?
A. "I should empty the pouch when it is one-third to one-half full."
B. "I can wait until the pouch is completely full to reduce waste."
C. "I will sit on the toilet to empty my ileostomy pouch."
D. "I should rinse the spout with water after emptying."
CORRECT ANSWER: B. "I can wait until the pouch is completely full to reduce
waste."
Rationale: Waiting until the pouch is completely full increases the risk of leakage, skin
irritation, and barrier detachment due to weight and pressure. Patients should empty
the pouch when it is one-third to one-half full. This practice maintains skin integrity,
prevents accidents, and extends wear time of the appliance.
Question 8: What is the primary rationale for using a convex skin barrier in ostomy
care?
A. To increase the aesthetic appearance of the pouching system
B. To apply gentle pressure that helps protrude a retracted or flush stoma for better
effluent direction
C. To reduce the cost of supplies by extending wear time
D. To eliminate the need for measuring the stoma
CORRECT ANSWER: B. To apply gentle pressure that helps protrude a retracted or
flush stoma for better effluent direction
Rationale: Convex barriers apply gentle, consistent pressure around the stoma to help
protrude flush or retracted stomas, directing effluent into the pouch and reducing the
risk of leakage and peristomal skin complications. Proper assessment and patient
instruction on convexity use are essential to avoid pressure-related complications.
Question 9: Which dietary recommendation is most appropriate for a patient with a
new colostomy?
A. Avoid all high-fiber foods permanently
B. Introduce one new food at a time and chew thoroughly
C. Consume only liquid diets for the first 6 months
D. Eliminate all dairy products to prevent gas
CORRECT ANSWER: B. Introduce one new food at a time and chew thoroughly
Rationale: After colostomy surgery, patients should gradually reintroduce foods,
introducing one new item at a time to assess tolerance. Chewing food thoroughly helps
prevent obstruction, especially important with colostomies where the lumen may be
narrower. Most patients can return to a regular diet with individualized modifications
based on tolerance.
, Question 10: What is the most common cause of peristomal skin irritation in
patients with ostomies?
A. Allergic reaction to pouching materials
B. Mechanical trauma from frequent pouch changes
C. Exposure to effluent due to improper barrier fit
D. Fungal infection from moisture accumulation
CORRECT ANSWER: C. Exposure to effluent due to improper barrier fit
Rationale: Irritant contact dermatitis from effluent exposure is the most frequent
peristomal skin complication. It occurs when the skin barrier opening is too large,
allowing stool or urine to contact the skin. Proper measurement, cutting the barrier to fit
within 1/8 inch of the stoma, and using skin protectants are key prevention strategies.
Question 11: Which statement best describes the purpose of a stoma cap?
A. To collect liquid effluent for patients with high-output ostomies
B. To provide irrigation capability for descending colostomies
C. To cover a well-formed stoma for patients who practice regular irrigation and have
predictable elimination
D. To protect the stoma during showering only
CORRECT ANSWER: C. To cover a well-formed stoma for patients who practice
regular irrigation and have predictable elimination
Rationale: Stoma caps are small, discreet covers used by patients with colostomies
(typically descending or sigmoid) who perform regular irrigation and have formed,
predictable stool. They are not suitable for ileostomies or urostomies due to continuous
liquid output. Proper patient selection and education are essential for successful use.
Question 12: When assessing a patient with a urostomy, which finding is
considered normal?
A. Cloudy, foul-smelling urine
B. Mucus strands in the urine
C. Bright red blood clots in the pouch
D. Absence of urine output for 6 hours
CORRECT ANSWER: B. Mucus strands in the urine
Rationale: Urostomies (ileal conduits) use a segment of intestine to divert urine, and
this intestinal segment continues to produce mucus. Mucus strands in the urine are
expected and normal. Patients should be taught to irrigate the stoma periodically to
prevent mucus buildup and obstruction. Cloudy, foul-smelling urine or absence of
output may indicate infection or obstruction and require evaluation.
