SECTION 1: PATIENT HISTORY & PSYCHOSOCIAL ASSESSMENT
QUESTION 1
During the initial I-human interview, Stefon Owens is a 12-year-old male who reluctantly admits he has been
leaking stool into his underwear for the past eight months. His mother reports he was fully toilet-trained by
age four. Which historical finding is most consistent with a primary diagnosis of functional encopresis with
overflow incontinence?
A. Daily passage of well-formed stool into the toilet without any soiling episodes
B. A pattern of stool withholding followed by periodic involuntary leakage of liquid stool
C. Constant dribbling of formed stool since birth without any toilet training success
D. Painful bowel movements with bright red blood coating the stool surface
Correct Answer: B
Rationale: Functional encopresis typically involves stool withholding behavior leading to fecal retention and eventual overflow of
liquid stool around the impacted mass. Daily normal bowel movements would rule out encopresis, while constant dribbling since
birth suggests an anatomic or neurologic cause.
QUESTION 2
The nurse conducting the I-human case review asks Stefon about his school attendance and social
relationships. Stefon becomes withdrawn and admits he avoids school on days when soiling is severe
because classmates have teased him. Which psychosocial consequence of encopresis poses the greatest
long-term risk to adolescent development?
A. Transient sleep disturbances that resolve with dietary fiber supplementation
B. Social isolation, academic decline, and developing low self-esteem
C. Temporary preference for sedentary video games over outdoor sports
D. Increased appetite for high-fiber foods as a compensatory behavior
Correct Answer: B
Rationale: Social isolation, academic decline, and low self-esteem are well-documented serious psychosocial sequelae of
encopresis in adolescents. These consequences can persist beyond resolution of the physical symptoms and significantly impair
developmental trajectory.
, QUESTION 3
Stefon's mother recalls that his symptoms began shortly after the family moved to a new city and he
started at a new middle school. She notes he was reluctant to use unfamiliar school restrooms and began
delaying bowel movements. Which psychosocial trigger most directly initiated Stefon's stool-withholding
behavior?
A. An innate neurological defect in rectal sensation present since birth
B. Environmental stress and toilet avoidance in an unfamiliar school setting
C. A genetic predisposition to inflammatory bowel disease triggered by moving
D. Accidental ingestion of a foreign object causing partial intestinal obstruction
Correct Answer: B
Rationale: Environmental stressors such as school changes and reluctance to use unfamiliar restrooms are common triggers for
stool withholding in children with functional encopresis. This behavioral pattern then leads to constipation and overflow
incontinence.
QUESTION 4
During a focused history, the clinician asks about Stefon's typical daily diet. His mother describes a pattern
of low fiber intake with frequent fast food, minimal fruits or vegetables, and inadequate water consumption.
Which dietary factor most directly contributes to the development of chronic constipation in this patient?
A. Excessive protein intake stimulating excessive gastric acid secretion
B. Insufficient dietary fiber resulting in decreased stool bulk and slower colonic transit
C. High sodium intake causing systemic fluid overload and edema
D. Inadequate fat consumption impairing absorption of fat-soluble vitamins
Correct Answer: B
Rationale: Dietary fiber increases stool bulk and promotes regular colonic motility. Low fiber intake is a major modifiable risk
factor for chronic constipation and encopresis in children. The other dietary factors are not directly linked to constipation
pathophysiology.
QUESTION 5
The pediatrician asks Stefon if he has experienced any painful bowel movements. Stefon nods and states
that passing hard stools has hurt for several months, which made him try to avoid defecating altogether.
Which conditioning mechanism best explains how painful defecation perpetuates the cycle of encopresis?
A. Positive reinforcement where pain motivates more frequent bathroom visits
B. Negative reinforcement where stool withholding avoids the aversive pain stimulus
C. Classical conditioning associating the school restroom with academic failure
D. Operant extinction where bowel movements no longer produce any consequences
Correct Answer: B
Rationale: Negative reinforcement occurs when a behavior (stool withholding) increases because it removes or avoids an
aversive stimulus (painful defecation). This behavioral mechanism is central to the perpetuation of functional fecal retention.
