SECTION 1: OSTOMY FUNDAMENTALS & ANATOMY (Questions 1-80)
Question 1: Which of the following structures are responsible for the highly
absorptive nature of the small bowel's surface?
A) Villi
B) Rugae
C) Peyer's patches
D) Taeniae coli
Correct Answer: A) Villi
Rationale: Villi are finger-like projections in the small intestine that greatly
increase the surface area for nutrient and fluid absorption. Rugae are folds in the
stomach, Peyer's patches are lymphoid tissue, and taeniae coli are longitudinal
muscle bands in the large intestine .
Question 2: The small intestine plays an important role in maintenance of fluid-
electrolyte balance.
A) True
B) False
Correct Answer: A) True
, Rationale: The small intestine is crucial for fluid and electrolyte balance, absorbing
approximately 5-8 liters of water and electrolytes daily. Disruption of this function
can lead to significant fluid and electrolyte imbalances, especially in patients with
high-output ileostomies .
Question 3: The amount and type of output from a newly created fecal stoma is
related to:
A) The time of day
B) The amount of parenteral fluids
C) The location in the intestinal tract
D) Fluid and electrolyte absorption
Correct Answer: C) The location in the intestinal tract
Rationale: The location of the stoma in the intestinal tract determines the
consistency and volume of output. Ileostomies produce liquid to semi-liquid
output due to minimal water absorption; colostomies produce more formed stool
as water is absorbed in the colon .
Question 4: What is an ostomy?
A) A surgical procedure that creates an artificial opening in the intestines leading
to the body's exterior
B) A procedure that repairs the stomach lining
C) A device used to measure waste output
