AANP Family Nurse Practitioner (FNP) Certification ExamAssessmentEasy
A 45-year-old male presents with a 2-month history of intermittent abdominal pain, bloating, and changes in bowel habits, alternating between constipation and diarrhea. His symptoms are relieved after defecation. He denies any weight loss, fever, or blood in his stool. Which diagnostic criteria set should the Family Nurse Practitioner use to confirm Irritable Bowel Syndrome (IBS)?
- AAmerican College of Gastroenterology (ACG) Guidelines
- BManning Criteria
- CRome IV Criteria
- DBristol Stool Chart
Show answer & explanationAnswer & explanation
Correct answer: C. Rome IV Criteria
The Rome IV Criteria are the most current and widely accepted diagnostic criteria for Irritable Bowel Syndrome (IBS). They define IBS based on recurrent abdominal pain associated with defecation or a change in stool frequency or form, occurring for at least 3 months with symptom onset at least 6 months prior.
Why the other options are wrong
- A. ACG Guidelines provide treatment recommendations but are not a set of diagnostic criteria themselves for IBS.
- B. Manning Criteria are older diagnostic criteria for IBS, largely superseded by Rome criteria.
- D. The Bristol Stool Chart is a tool to classify stool form, not a diagnostic criterion for IBS.
IBS Rome IV Diagnostic Criteria
The Rome IV Criteria are the current, symptom-based diagnostic criteria for Irritable Bowel Syndrome (IBS), requiring recurrent abdominal pain at least 1 day/week in the last 3 months, associated with defecation or change in stool frequency/form, with symptom onset at least 6 months prior.
- Focus on abdominal pain associated with bowel movements.
- Requires chronicity: symptoms for at least 3 months, onset 6 months prior.
- Absence of alarm symptoms (e.g., weight loss, blood in stool) is important.
