(PrepU) Chapter 41: Management of Patients with Intestinal and Rectal Disorders

A community health nurse is performing a home visit to a 53-year-old patient who requires twice-weekly wound care on her foot. The patient mentions that she is currently having hemorrhoids, a problem that she has not previously experienced. What treatment measure should the nurse recommend to this patient?

A high-fiber diet with increased fruit intake Hemorrhoid symptoms and discomfort can be relieved by good personal hygiene and by avoiding excessive straining during defecation. A high-residue diet that contains fruit and bran along with an increased fluid intake may be all the treatment necessary to promote the passage of soft, bulky stools to prevent straining. It is unnecessary to avoid showering, and antibiotics are not an effective treatment.

A client reports constipation. Which nursing measure would be most effective in helping the client reduce constipation?

Assist client to increase dietary fiber. The nurse should assist the client to increase the dietary fiber in food because it helps reduce constipation. Providing an adequate quantity of food is necessary in maintaining sufficient nutrition and in sustaining normal body weight. Obtaining medical, allergy, and food history would provide valuable information, however, it would not help reduce constipation.

A 75-year-old male patient presents at the emergency department with symptoms of a small bowel obstruction. An emergency room nurse is obtaining assessment data from this patient. What assessment finding is characteristic of a small bowel obstruction?

Nausea and vomiting Nausea and vomiting are symptoms of a small bowel obstruction. Decrease in urine production and mucosal edema are not symptoms of a bowel obstruction. The patient may defecate mucus, but this is not accompanied by stool.

A client is admitted to the hospital for diagnostic testing to rule out colorectal cancer. Which intervention should the nurse include on the plan of care?

Test all stools for occult blood. Blood in the stools is one of the warning signs of colorectal cancer. The nurse should plan on checking all stools for both frank and occult blood. The blood in the stool is coming from the colon or rectum; administering an ointment wouldn't help decrease the bleeding. Preparing a client for a gastrostomy tube isn't appropriate when diagnosing colorectal cancer. Colorectal cancer is usually painless; administering opioid pain medication isn't needed

A client tells the nurse, "I am not having normal bowel movements." When differentiating between what are normal and abnormal bowel habits, what indicators are the most important?

The consistency of stool and comfort when passing stool In differentiating normal from abnormal, the consistency of stools and the comfort with which a person passes them are more reliable indicators than is the frequency of bowel elimination. People differ greatly in their bowel habits and normal bowel patterns range from three bowel movements per day to three bowel movements per week. It is important for the stool to be soft to pass without pain. The client may not be able to fully evacuate with a bowel movement; it may take time.

A client reports taking a stimulant laxative in order to be able to have a bowel movement daily. What should the nurse inform the client about taking a stimulant laxative?

They can be habit forming and will require increasing doses to be effective. The nurse should discourage self-treatment with daily or frequent enemas or laxatives. Chronic use of such products causes natural bowel function to be sluggish. In addition, laxatives continuing stimulants can be habit forming, requiring continued use in increasing doses. Although the nurse should encourage the client to have adequate fluid intake, laxative use should not be encouraged. The laxative may interact with other medications the client is taking and may cause a decrease in absorption. A fiber supplement may be taken alone but should not be taken with a stimulant laxative.

The presence of mucus and pus in the stools suggests which condition?

Ulcerative colitis The presence of mucus and pus in the stools suggests ulcerative colitis. Watery stools are characteristic of small-bowel disease. Loose, semisolid stools are associated more often with disorders of the colon. Voluminous, greasy stools suggest intestinal malabsorption.

Diet therapy for clients diagnosed with irritable bowel syndrome (IBS) includes:

high-fiber diet. A high-fiber diet is prescribed to help control constipation. Individuals experiencing diarrhea may be advised to eat a low-fiber diet. Foods that are possible irritants, such as caffeine, spicy foods, lactose, beans, fried foods, corn, wheat, and alcohol, should be avoided. Fluids should not be taken with meals because they cause abdominal distention.

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?

Abdominoperineal resection 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.

The nurse is performing an abdominal assessment for a patient with diarrhea and auscultates a loud rumbling sound in the left lower quadrant. What will the nurse document this sound as on the nurse's notes?

Borborygmus Borborygmus is a rumbling noise caused by the movement of gas through the intestines, often associated with diarrhea.

A patient with IBD would be encouraged to increase fluids, use vitamins and iron supplements, and follow a diet designed to reduce inflammation. Select the meal choice that would be recommended for a low-residue diet.

Broiled chicken with low-fiber pasta A low-residue, high-protein, and high-calorie diet is recommended to reduce the size and number of stools. Foods to avoid include yogurt, fruit, salami, and peanut butter.

A client is diagnosed with Zollinger-Ellison syndrome. The nurse knows to assess the client for which characteristic clinical feature of this syndrome?

Steatorrhea Hyperacidity in the duodenum inactivates pancreatic enzymes causing steatorrhea and ulcer diathesis.

A client realizes that regular use of laxatives has greatly improved bowel patterns. However, the nurse cautions this client against the prolonged use of laxatives for which reason?

The client's natural bowel function may become sluggish. 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.

The nurse caring for an older adult client diagnosed with diarrhea is administering and monitoring the client's medications. Because one of the client's medications is digitalis (digoxin), the nurse monitors the client closely for:

hypokalemia The older client taking digoxin must be aware of how quickly dehydration and hypokalemia can occur with diarrhea. The nurse teaches the client to recognize the symptoms of hypokalemia because low levels of potassium intensify the action of digitalis, leading to digitalis toxicity.

After undergoing a total cystectomy and urinary diversion, a client has a Kock pouch (continent internal reservoir) in place. Which statement by the client indicates a need for further teaching?

"I'll have to wear an external collection pouch for the rest of my life." The client requires additional teaching if he states that he'll have to wear an external collection pouch for the rest of his life. An internal collection pouch, such as the Kock pouch, allows the client to perform self-catheterization for ileal drainage. This pouch is an internal reservoir, eliminating the need for an external collection pouch. A well-balanced diet is essential for healing; the client need not include or exclude particular foods. The client should drink at least eight glasses of fluid daily to prevent calculi formation and urinary tract infection. Intervals between pouch drainings should be increased gradually until the pouch is emptied two to four times daily.

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?

Chronic constipation with sporadic bouts of diarrhea 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.

A patient is suspected to have diverticulosis without symptoms of diverticulitis. What diagnostic test does the nurse anticipate educating the patient about prior to scheduling?

Colonoscopy Diverticulosis is typically diagnosed by colonoscopy, which permits visualization of the extent of diverticular disease and biopsy of tissue to rule out other diseases. In the past, barium enema was the preferred diagnostic test, but it is now used less frequently than colonoscopy. CT with contrast agent is the diagnostic test of choice if the suspected diagnosis is diverticulitis; it can also reveal abscesses.

The nurse is caring for a 77-year-old patient diagnosed with Crohn's disease. What would be especially important to monitor this patient for?

Dehydration Elderly patients can become dehydrated quickly and develop low potassium levels (i.e., hypokalemia) as a result of diarrhea. The nurse observes for clinical manifestations of muscle weakness, dysrhythmias, or decreased peristaltic motility that may lead to paralytic ileus. All options would be important to monitor, but especially important is monitoring for dehydration.

The nurse is teaching a client with an ostomy how to change the pouching system. Which information should the nurse include when teaching a client with no peristomal skin irritation?

Dry skin thoroughly after washing The nurse should teach the client without peristomal skin irritation to dry the skin thoroughly after washing. Barrier powder, triamcinolone acetonide spray, and nystatin powder are used when the client has peristomal skin irritation and/or fungal infection.

A nurse is applying an ostomy appliance to the ileostomy of a client with ulcerative colitis. Which action is appropriate?

Gently washing the area surrounding the stoma using a facecloth and mild soap For a client with an ostomy, maintaining skin integrity is a priority. The nurse should gently wash the area surrounding the stoma using a facecloth and mild soap. Scrubbing the area around the stoma can damage the skin and cause bleeding. The faceplate opening should be no more than 1/8-inch to 1/6-inch larger than the stoma. This size protects the skin from exposure to irritating fecal material. The nurse can create an adequate seal and prevent leakage of fecal material from under the faceplate by applying a thin layer of skin barrier and smoothing out wrinkles in the faceplate. Eliminating wrinkles in the faceplate also protects the skin surrounding the stoma from pressure.

An elderly client diagnosed with diarrhea is taking digoxin. Which electrolyte imbalance should the nurse be alert to?

Hypokalemia The older client taking digitalis must be aware of how quickly dehydration and hypokalemia can occur with diarrhea. The nurse teaches the client to recognize the symptoms of hypokalemia because low levels of potassium intensify the action of digitalis, leading to digitalis toxicity.

A client is recovering from an ileostomy that was performed to treat inflammatory bowel disease. During discharge teaching, what would the nurse stress the importance of?

Increasing fluid intake to prevent dehydration Because stool forms in the large intestine, an ileostomy typically drains liquid waste. To avoid fluid loss through ileostomy drainage, the nurse should instruct the client to increase fluid intake. The nurse should teach the client to wear a collection appliance at all times because ileostomy drainage is incontinent, to avoid high-fiber foods because they may irritate the intestines, and to avoid enteric-coated medications because the body can't absorb them after an ileostomy.

Vomiting results in which of the following acid-base imbalances?

Metabolic alkalosis Vomiting results in loss of hydrochloric acid (HCl) and potassium from the stomach, leading to a reduction of chlorides and potassium in the blood and to metabolic alkalosis.

When preparing a client for surgery to treat appendicitis, the nurse formulates a nursing diagnosis of Risk for infection related to inflammation, perforation, and surgery. What is the rationale for choosing this nursing diagnosis?

Obstruction of the appendix reduces arterial flow, leading to ischemia, inflammation, and rupture of the appendix. A client with appendicitis is at Risk for infection related to inflammation, perforation, and surgery because obstruction of the appendix causes mucus fluid to build up, increasing pressure in the appendix and compressing venous outflow drainage. The pressure continues to rise with venous obstruction; arterial blood flow then decreases, leading to ischemia from lack of perfusion. Inflammation and bacterial growth follow, and swelling continues to raise pressure within the appendix, resulting in gangrene and rupture. Elderly, not middle-aged, clients are especially susceptible to appendix rupture.

The nurse is caring for a client with intussusception of the bowel. What does the nurse understand occurs with this disorder?

One part of the intestine telescopes into another portion of the intestine. 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.

During assessment of a client for a malabsorption disorder, the nurse notes a history of abdominal pain and weight loss, marked steatorrhea, azotorrhea, and frequent glucose intolerance. Based on these clinical features, what diagnosis will the nurse suspect?

Pancreatic insufficiency These symptoms are consistent with a diagnosis of pancreatic insufficiency. Loss of ileal absorbing surface results in ileal dysfunction. A toxic response to gluten is characteristic of celiac disease, and a deficiency of intestinal lactase results in lactose intolerance.

A client with a diagnosis of acute appendicitis is awaiting surgical intervention. The nurse listens to bowel sounds and hears none and observes that the abdomen is rigid and board-like. What complication does the nurse determine may be occurring at this time?

Peritonitis Lack of bowel motility typically accompanies peritonitis. The abdomen feels rigid and board-like as it distends with gas and intestinal contents. Bowel sounds typically are absent. The diagnosis of acute appendicitis correlates with the symptoms of rupture of the appendix and peritonitis. A paralytic ileus and gas alone do not produce these symptoms.

Which of the following is the most common symptom of a polyp?

Rectal bleeding The most common symptom is rectal bleeding. Lower abdominal pain may also occur. Diarrhea and anorexia are clinical manifestations of ulcerative colitis.
