A client is diagnosed with colon cancer, located in the lower third of the rectum. What does the nurse understand will be the surgical treatment option for this client?
- A. Colectomy
- B. Segmental resection
- C. Abdominoperineal resection
- D. A low colectomy
Correct Answer: C
Rationale: A cancerous mass in the lower third of the rectum will result in an abdominoperineal resection with a wide excision of the rectum and the creation of a sigmoid colostomy. An encapsulated colorectal tumor may be removed without taking away surrounding healthy tissue. This type of tumor, however, may call for partial or complete surgical removal of the colon (colectomy). Occasionally, the tumor causes a partial or complete bowel obstruction. If the tumor is in the colon and upper third of the rectum, a segmental resection is performed. In this procedure, the surgeon removes the cancerous portion of the colon and rejoins the remaining portions of the GI tract to restore normal intestinal continuity.

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?
- A. Abdominal distention
- B. Frank blood in the stool
- C. A change in bowel habits
- D. Abdominal pain
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.
A client informs the nurse of having abdominal pain that is relieved when having a bowel movement. The health care provider diagnosed the client with irritable bowel syndrome. What does the nurse recognize as characteristic of this disorder?
- A. Weight loss due to malabsorption
- B. Blood and mucus in the stool
- C. Chronic constipation with sporadic bouts of diarrhea.
- D. Client is awakened from sleep due to abdominal pain.
Correct Answer: C
Rationale: Most clients with irritable bowel syndrome (IBS) describe having chronic constipation with sporadic bouts of diarrhea. Some report the opposite pattern, although less commonly. Most clients experience various degrees of abdominal pain that defecation may relieve. Weight usually remains stable, indicating that when diarrhea occurs, malabsorption of nutrients does not accompany it. Stools may have mucus, but blood is not usually found because the bowel is not locally inflamed. The sleep is not disturbed from abdominal pain.
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.
- A. Oral candidiasis
- B. Dehydration
- C. Electrolyte imbalances
- D. Vitamin deficiencies
- E. Rectal fissures
Correct Answer: B,C,D
Rationale: Three major problems associated with severe or prolonged diarrhea include dehydration, electrolyte imbalances, and vitamin deficiencies.
Which test will best determine whether a client has an abnormality of the muscles surrounding the anal sphincter?
- A. Kidneys, ureters, bladder (KUB)
- B. Colonic transit studies
- C. Defecography
- D. Abdominal radiography
Correct Answer: C
Rationale: In defecography, a thick barium paste is inserted into the rectum. Radiographs are taken as the client expels the barium to determine whether there are any anatomic abnormalities or problems with the muscles surrounding the anal sphincter. A KUB will not determine this. Colonic transit studies are used to determine how long it takes for food to travel through the intestines. Abdominal radiography will show the structure but does not determine the muscle ability surrounding the anal sphincter.
The nurse observes the physician palpating the abdomen of a client that is suspected of having acute appendicitis. When the abdomen is pressed in the left lower quadrant the client complains of pain on the right side. What does the nurse understand this assessment technique is referred to?
- A. Referred pain
- B. Rebound pain
- C. Rovsing sign
- D. Cremasteric reflex
Correct Answer: C
Rationale: When an examiner deeply palpates the left lower abdominal quadrant and the client feels pain in the right lower quadrant, this is referred to as a positive Rovsing sign and suggests acute appendicitis. Referred pain indicates pain in another area but is not necessarily manipulated by the examiner. Rebound pain is indicated when the pain of palpation is worse when the pressure is off the site. The cremasteric reflex is a superficial reflex that is present in male clients.
