Introduction
This comprehensive practice examination is designed to assess the foundational and
applied knowledge required for proficient ostomy care. It covers a wide array of
topics, including anatomy, surgical indications, patient education, and the
management of complex clinical scenarios. The questions are structured to evaluate
critical thinking and clinical decision-making skills essential for real-world practice.
A combination of theoretical knowledge and scenario-based questions is utilized to
ensure a holistic assessment. The emphasis is on practical application, from stoma
assessment and skin care to addressing the psychosocial needs of individuals living
with an ostomy. This exam serves as a valuable tool for both learning and self-
evaluation.
SECTION ONE: QUESTIONS 1–50
,1. A nurse is teaching a patient about the anatomy of the digestive system in
preparation for a colostomy. The nurse correctly identifies that the primary
function of the large intestine is which of the following?
A. Absorption of most nutrients
B. Reabsorption of water and electrolytes
C. Mechanical breakdown of food
D. Secretion of digestive enzymes
🟢 Correct Answer: B. Reabsorption of water and electrolytes
🔴 Explanation: The large intestine's main function is to reabsorb water and
electrolytes from the remaining chyme, forming solid stool. The small intestine is
responsible for most nutrient absorption, mechanical breakdown occurs in the
mouth and stomach, and digestive enzymes are secreted by the pancreas and
small intestine.
2. A patient with bladder cancer is scheduled for a cystectomy and ileal
conduit. The nurse explains that this type of urinary diversion is characterized
by:
A. The use of the sigmoid colon to create a neobladder
B. A continent pouch created from the stomach
C. The ureters being implanted into a segment of the ileum that is brought to the
skin surface
D. The creation of a stoma from the appendix
🟢 Correct Answer: C. The ureters being implanted into a segment of the ileum
that is brought to the skin surface
🔴 Explanation: An ileal conduit is the most common type of incontinent urinary
diversion. A segment of the ileum is isolated, with one end closed. The ureters are
,implanted into this segment, and the other end is brought to the abdominal wall
to form a stoma. The urine continuously drains into a pouch.
3. A patient is two days post-operative from a transverse loop colostomy.
Which assessment finding would be the most concerning and should be
reported to the surgeon immediately?
A. A stoma that is edematous and appears deep red to purple
B. A moderate amount of serosanguineous drainage on the dressing
C. The patient reporting a mild burning sensation around the stoma
D. The stoma measuring approximately 3 cm in diameter
🟢 Correct Answer: A. A stoma that is edematous and appears deep red to purple
🔴 Explanation: Post-operative edema is normal, but a stoma that is dark red,
purple, or black indicates compromised blood supply and potential necrosis. This
is a critical finding requiring immediate surgical intervention. Serosanguineous
drainage and mild burning are expected, while a 3 cm diameter is within the
normal range.
4. The nurse is preparing to change an ostomy pouching system. Which of the
following steps is essential to ensure proper adhesion and prevent skin
breakdown?
A. Applying a skin barrier wipe and allowing it to dry completely
B. Using a hairdryer on a hot setting to warm the adhesive
C. Cutting the skin barrier opening exactly 1/8 inch larger than the stoma
D. Applying a thick layer of zinc oxide paste around the stoma
🟢 Correct Answer: A. Applying a skin barrier wipe and allowing it to dry
completely
🔴 Explanation: A skin barrier wipe provides a protective layer between the skin
and the adhesive. Allowing it to dry completely ensures maximum adhesion and
, prevents moisture from compromising the seal. Cutting the opening exactly 1/8
inch larger than the stoma is incorrect, it should be cut no more than 1/8 inch
larger, but ideally as close to the stoma size as possible. Heat should be avoided,
and thick pastes can cause leakage.
5. The nurse is evaluating a patient's understanding of dietary changes
following an ileostomy. Which statement indicates a correct understanding?
A. "I should avoid all high-fiber foods to prevent a blockage."
B. "It is important to drink at least 2 liters of fluids daily to prevent dehydration."
C. "I need to eat large meals at one time to ensure adequate nutrition."
D. "My favorite foods before surgery are what I will continue to eat now."
🟢 Correct Answer: B. "It is important to drink at least 2 liters of fluids daily to
prevent dehydration."
🔴 Explanation: Patients with an ileostomy are at high risk for dehydration due to
fluid loss in the liquid effluent. Drinking at least 2 liters of fluid daily is crucial.
While high-fiber foods should be introduced slowly and chewed well, they are not
entirely avoided. Small, frequent meals are often better tolerated, and dietary
habits may need to be adjusted.
6. A patient with a colostomy reports that the pouching system is leaking
frequently. What is the most important initial assessment the nurse should
perform?
A. Evaluate the patient's dietary intake for gas-producing foods
B. Check the size of the stoma and compare it to the opening on the pouch
C. Assess the patient's emotional state and coping mechanisms
D. Instruct the patient on how to apply a barrier ring
🟢 Correct Answer: B. Check the size of the stoma and compare it to the opening
on the pouch
