Chapter 46 : Caring for Clients With Disorders of the Lower Gastrointestinal Tract Questions
Question 1 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 2 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 3 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.
Question 4 of 5
The instructor is teaching a group of students about Crohn disease and antidiarrheal agents. The instructor determines that the teaching was effective when the students identify which of the following as an example of an opiate-based antidiarrheal agent?
Correct Answer: A
Rationale: Diphenoxylate with atropine is an example of an opiate-based antidiarrheal agent. Bismuth subsalicylate and kaolin and pectin are examples of absorbent antidiarrheal agents. Bisacodyl is a chemical stimulant laxative.
Question 5 of 5
A client realizes that regular use of laxatives has led to bowel pattern improvement. However, the nurse cautions this client against the prolonged use of laxatives for which reason?
Correct Answer: C
Rationale: It is essential for the nurse to caution the client against the prolonged use of laxatives because it decreases muscle tone in the large intestine. Prolonged use of laxatives may cause the client's natural bowel function to become sluggish. Laxatives do not increase the risk of developing inflammatory bowel disease, arthritis, or arthralgia, nor do they cause a loss in appetite.
