1. A patient is 2 days post-op from a Brooke Ileostomy. The stoma is dark red,
moist, and slightly edematous. The nurse should:
A) Notify the surgeon immediately for possible necrosis
B) Document as a normal post-operative finding
C) Apply a ice pack to reduce swelling
D) Request a stat surgical consult
A "beefy red" or dark pink stoma that is moist and slightly swollen is expected in
the first 48–72 hours post-op.
2. A patient with a new Jejunostomy is at highest risk for which complication?
A) Constipation
B) Severe dehydration and electrolyte imbalance
C) Formation of hard stool bolus
D) Vitamin B12 deficiency only
Because the jejunum is higher in the GI tract, output is very high (watery) and
nutrient absorption time is minimal, leading to rapid dehydration.
3. During preoperative site selection for a stoma, the nurse should avoid:
A) The apex of the infraumbilical mound
B) Skin folds, scars, and the belt line
C) The rectus muscle
D) The right lower quadrant
Placing a stoma in a skin fold or under a belt line leads to pouch leakage and skin
breakdown.
4. A patient with a Sigmoid Colostomy asks why their stool is formed while their
friend with an Ileostomy has liquid stool. The nurse explains:
A) The friend has an infection
B) The colon's primary job is to absorb water; the further down the tract, the
,more formed the stool
C) It depends on the patient's diet only
D) The sigmoid colostomy is temporary
The ascending colon and small intestine (ileum) produce liquid waste; the
descending/sigmoid colon allows for water reabsorption.
5. Which of the following is an "expected" finding in a patient with an Ileal
Conduit?
A) Clear, amber urine without sediment
B) Urine containing mucus threads
C) Cloudy, foul-smelling urine
D) Bloody urine after 2 weeks post-op
Because a segment of the ileum (which produces mucus) is used to create the
conduit, mucus in the urine is normal and expected.
6. A patient presents with a stoma that has turned dusky, purple-black, and
feels cool to the touch. This indicates:
A) Normal bruising
B) Peristomal skin irritation
C) Stoma necrosis (impaired blood flow)
D) Impending stoma prolapse
Dusky or black coloring suggests ischemia/necrosis, which is a surgical
emergency.
7. When teaching a patient to empty their pouch, the nurse advises emptying it
when it is:
A) Completely full
B) 1/3 to 1/2 full
C) Only once a day
D) Every time they use the bathroom
Emptying at 1/3 to 1/2 full prevents the weight of the pouch from pulling the
wafer off the skin.
8. A patient with an Ileostomy is concerned about "pancaking." The nurse
should explain that pancaking is:
A) Liquid output that leaks under the wafer
B) Stool that sits at the top of the pouch and does not drop down, often seen in
, colostomies
C) A type of skin infection
D) The term for a flat stoma
Pancaking is more common in colostomies with thicker stool, but patients often
confuse terms; it involves stool sticking to the stoma/top of the bag.
9. What is the primary purpose of using "Stoma Powder" on peristomal skin?
A) To make the wafer stick better to dry skin
B) To absorb moisture from denuded/weeping skin (Crusting technique)
C) To prevent fungal infections in all patients
D) To lubricate the stoma
Powder should only be used on moist, denuded skin. It is used in the "crust"
method (powder + skin prep) to create a dry surface for the wafer.
10. A patient with an Indiana Pouch (Continent Urinary Diversion) should be
taught to:
A) Wear a pouch at all times
B) Catheterize the stoma on a regular schedule to empty the internal reservoir
C) Irrigate the stoma with 500mL of water daily
D) Expect urine to leak constantly
Continent diversions like the Indiana Pouch require the patient to perform
intermittent catheterization.
11. Which peristomal skin complication is characterized by a "cobblestone"
appearance and is often seen in Crohn’s disease?
A) Candidiasis
B) Pyoderma Gangrenosum (PG)
C) Irritant Dermatitis
D) Folliculitis
PG presents as painful, ulcerated lesions with violaceous borders; it is an
inflammatory condition often associated with IBD.
12. The "Acid Mantle" of the skin has a pH of approximately:
A) 2.5–3.5
B) 4.5–6.5
C) 7.0–8.0
D) 9.0–10.0
