Chapter 46 : Caring for Clients With Disorders of the Lower Gastrointestinal Tract Questions
Question 1 of 5
The nurse is caring for a client with intussusception of the bowel. What does the nurse understand occurs with this disorder?
Correct Answer: B
Rationale: In intussusception of the bowel, one part of the intestine telescopes into another portion of the intestine. When the bowel twists and turns itself and obstructs the intestinal lumen, this is known as a volvulus. A hernia is when the bowel protrudes through a weakened area in the abdominal wall. An adhesion is a loop of intestine that adheres to an area that is healing slowly after surgery.
Question 2 of 5
The nurse is caring for a client who has had diarrhea for 3 days. What major problem(s) associated with severe or prolonged diarrhea should the nurse monitor for when caring for this client? Select all that apply.
Correct Answer: B,C,D
Rationale: Three major problems associated with severe or prolonged diarrhea include dehydration, electrolyte imbalances, and vitamin deficiencies.
Question 3 of 5
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?
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.
Question 4 of 5
A nurse is preparing a presentation for a local community group of older adults about colon cancer. What would the nurse include as the primary characteristic associated with this disorder?
Correct Answer: C
Rationale: Although abdominal distention and blood in the stool (frank or occult) may be present, the chief characteristic of cancer of the colon is a change in bowel habits, such as alternating constipation and diarrhea. Abdominal pain is a late sign.
Question 5 of 5
The nurse is interviewing a client with internal hemorrhoids. What would the nurse expect the client to report?
Correct Answer: A
Rationale: Internal hemorrhoids cause bleeding but are less likely to cause pain, unless they protrude through the anus. External hemorrhoids may cause few symptoms, or they can produce pain, itching, and soreness of the anal area.
