200 Sample Practice Questions with Rationales
1. A patient is 3 days post-op from an
abdominoperineal resection (APR). Which type of
ostomy would you expect to see?
• A) Temporary loop ileostomy
• B) Permanent end colostomy
• C) Temporary end colostomy
• D) Permanent end ileostomy
Correct ☑VERIFIED ANSWER: B) Permanent end
colostomy
,2
Rationale: An abdominoperineal resection involves
the removal of the rectum, anus, and sphincter
mechanism. As the remaining colon is intact and the
anus is removed, a permanent end colostomy is
formed in the left lower quadrant, making a closure
impossible.
2. A patient with a new ileostomy reports frequent
leakage from the bottom edge of the wafer. On
assessment, the peristomal skin below the stoma
is denuded and painful. What is the most likely
etiology of this skin breakdown?
• A) Suture granulomas
• B) Allergic dermatitis
• C) Peristomal candidiasis
• D) Irritant dermatitis
Correct ☑VERIFIED ANSWER: D) Irritant dermatitis
,3
Rationale: Irritant dermatitis is the most common
peristomal skin complication and is caused by
contact with caustic fecal effluent. The patient's
history of leakage from the bottom edge directly
correlates with the location of the denuded, painful
skin.
3. When performing a stoma site marking prior to
surgery for a patient with rectal adenocarcinoma,
the WOC nurse should consider possible surgical
options. What is the most appropriate approach?
• A) Mark only the right lower quadrant
• B) Mark only the left lower quadrant
• C) Mark both the right and left lower quadrants
• D) Mark a single site based on patient
preference
Correct ☑VERIFIED ANSWER: C) Mark both the
right and left lower quadrants
, 4
Rationale: The location of the tumor will determine
the surgery. If the tumor is low, an APR with a
permanent colostomy in the LLQ will be performed.
If sphincter function can be preserved, a low
anterior resection with a protective loop ileostomy
in the RLQ will be done. Marking both sites is
proactive and prepared for either outcome.
4. A patient with an ileal pouch-anal anastomosis
(IPAA) presents with symptoms of acute pouchitis
for the first time, 3 months after the ileostomy was
closed. What is the first-line treatment you would
recommend?
• A) Infliximab
• B) Amoxicillin/clavulanic acid
• C) Ciprofloxacin
• D) Sulfamethoxazole/trimethoprim
Correct ☑VERIFIED ANSWER: C) Ciprofloxacin
