Review Timby's Introductory Medical-Surgical Nursing Thirteenth, North American Edition - Caring for Clients With Disorders of the Lower Gastrointestinal Tract related questions and content

The instructor is teaching a group of students about intestinal obstruction. The instructor determines that the teaching was effective when the students identify which of the following as a cause of a functional obstruction?

  • A. Volvolus
  • B. Intussusception
  • C. Tumor
  • D. Abdominal surgery
Correct Answer: D

Rationale: In functional obstruction, the intestine can become adynamic from an absence of normal nerve stimulation to intestinal muscle fibers. For example, abdominal surgery can lead to paralytic ileus. Mechanical obstructions result from a narrowing of the bowel lumen with or without a space-occupying mass. A mass may include a tumor, adhesions (fibrous bands that constrict tissue), incarcerated or strangulated hernias, volvulus (kinking of a portion of intestine), intussusception (telescoping of one part of the intestine into an adjacent part), or impacted feces or barium.
