Celiac sprue is an example of which category of malabsorption?

Mucosal disorders causing generalized malabsorption Explanation: In addition to celiac sprue, regional enteritis and radiation enteritis are examples of mucosal disorders. Examples of infectious diseases causing generalized malabsorption include small-bowel bacterial overgrowth, tropical sprue, and Whipple disease. Examples of luminal problems causing malabsorption include bile acid deficiency, Zollinger-Ellison syndrome, and pancreatic insufficiency. Postoperative gastric or intestinal resection can result in development of malabsorption syndromes.

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 boardlike. What complication does the nurse determine may be occurring at this time?

Peritonitis Explanation: Lack of bowel motility typically accompanies peritonitis. The abdomen feels rigid and boardlike 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.

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 Explanation: 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.

Nursing assessment of a client with peritonitis reveals hypotension, tachycardia, and signs and symptoms of dehydration. The nurse also expects to find:

severe abdominal pain with direct palpation or rebound tenderness. Explanation: Peritonitis decreases intestinal motility and causes intestinal distention. A classic sign of peritonitis is a sudden, diffuse, severe abdominal pain that intensifies in the area of the underlying causative disorder (such as appendicitis, diverticulitis, ulcerative colitis, or a strangulated obstruction). The client may also have rebound tenderness. Tenderness and pain in the right upper abdominal quadrant suggest cholecystitis. Jaundice and vomiting are signs of cirrhosis of the liver. Rectal bleeding or a change in bowel habits may indicate colorectal cancer.

A client is readmitted with an exacerbation of celiac disease 2 weeks after discharge. Which statement by the client indicates the need for a dietary consult?

"I didn't eat anything I shouldn't have; I just ate roast beef on rye bread." Explanation: The client stating that he ate roast beef on rye bread indicates the need for a dietary consult because rye bread contains gluten, which must be eliminated from the client's diet. The client stating that he's followed the ordered medication regimen and diet doesn't suggest that the client needs a dietary consult; a treatment regimen consisting of medications to improve symptoms and dietary modification is necessary to treat celiac disease. The client stating that he hasn't traveled outside of the country doesn't suggest that dietary concerns exist. The client saying that he can't have oatmeal shows an understanding of the dietary restrictions necessary with celiac disease.

A patient arrives in the emergency department with complaints of right lower abdominal pain that began 4 hours ago and is getting worse. The nurse assesses rebound tenderness at McBurney's point. What does this assessment data indicate to the nurse?

Appendicitis Explanation: In up to 50% of presenting cases of appendicitis, local tenderness is elicited at McBurney's point when pressure is applied (Black & Martin, 2012) (Fig. 48-3). Rebound tenderness (i.e., production or intensification of pain when pressure is released) may be present.

Which of the following is a term used to describe intestinal rumbling?

Borborygmus Explanation: Borborygmus is intestinal rumbling. Ineffective straining is tenesmus. Malabsorption is the inability of the digestive system to absorb one or more of the major vitamins, minerals, and nutrients. Decreased muscle tone that occur with aging.

In women, which of the following types of cancer exceeds colorectal cancer?

Breast Explanation: In women, only incidences of breast cancer exceed that of colorectal cancer. In men, only incidences of prostate cancer and lung cancer exceed that of colorectal cancer.

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 Explanation: Elderly patients can become dehydrated quickly and develop low potassium levels (ie, 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.

A nurse is preparing a presentation for a local community group of older adults about colon cancer. Which of the following would the nurse include as the primary characteristic associated with this disorder?

A change in bowel habits Explanation: 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.

The nurse is talking with a group of clients who are older than age 50 years about the recognition of colon cancer to access early intervention. What should the nurse inform the clients to report immediately to their primary care provider?

Change in bowel habits Explanation: The chief characteristic of cancer of the colon is a change in bowel habits, such as alternating constipation and diarrhea. Excess gas, daily bowel movements, and abdominal cramping when having a bowel movement are not indicators of colon cancer.

The nurse is irrigating a colostomy when the patient says, "You will have to stop, I am cramping so badly." What is the priority action by the nurse?

Clamp the tubing and give the patient a rest period. Explanation: When irrigating a colostomy, the nurse should allow tepid fluid to enter the colon slowly. If cramping occurs, the nurse should clamp off the tubing and allow the patient to rest before progressing. Water should flow in over a 5- to 10-minute period.

A client is being treated for diverticulosis. Which information should the nurse include in this client's teaching plan?

Drink at least 8 to 10 large glasses of fluid every day Explanation: The nurse should instruct a client with diverticulosis to drink at least 8 to 10 large glasses of fluid every day. The client should include unprocessed bran in the diet because it adds bulk, and should avoid the use of laxatives or enemas except when recommended by the physician. In addition, regular exercise should be encouraged if the client's current lifestyle is somewhat inactive.

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 Explanation: 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 client has been recently diagnosed with an anorectal condition. The nurse is reviewing interventions that will assist the client with managing the therapeutic regimen. What would not be included?

Encourage the client to avoid exercise. Explanation: Activity promotes healing and normal stool patterns. Proper cleansing prevents infection and irritation. Sitz baths promote healing, decrease skin irritation, and relieve rectal spasms. Encouragement promotes compliance with therapeutic regimen and prevents complications.

The nurse is caring for a patient diagnosed with abdominal perforation. Which of the following is a clinical manifestation of this disease process?

Hypotension Explanation: Clinical manifestations include hypotension, increased temperature, tachycardia, and elevated ESR.

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 Explanation: 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.

Which of the following will the nurse observe as symptoms of perforation in a patient with intestinal obstruction?

Sudden, sustained abdominal pain Explanation: Sudden, sustained pain, abdominal distention, and fever are symptoms of perforation in a client with intestinal obstruction. A decrease in blood pressure and decrease in urine output are symptoms of shock. Purulent drainage from the gluteal fold is not a symptom of perforation; it only indicates that the client has developed a condition of anorectal abscess.

The nurse is assessing a client for constipation. Which review should the nurse conduct first to identify the cause of constipation?

Usual pattern of elimination Explanation: Constipation has many possible causes and assessing the client's usual pattern of elimination is the first step in identifying the cause. The nurse should obtain a description of the bowel elimination pattern, asking about the frequency, overall appearance and consistency of stool, blood in the stool, pain, and effort necessary to pass stool. It is also essential for the nurse to review the client's current medications, diet, and activity levels.

The nurse is assigned to care for a patient 2 days after an appendectomy due to a ruptured appendix with resultant peritonitis. The nurse has just assisted the patient with ambulation to the bedside commode when the patient points to the surgical site and informs the nurse that "something gave way." What does the nurse suspect may have occurred?

Wound dehiscence has occurred. Explanation: Any suggestion from the patient that an area of the abdomen is tender or painful or "feels as if something just gave way" must be reported. The sudden occurrence of serosanguineous wound drainage strongly suggests wound dehiscence (see Chapter 19).

A longitudinal tear or ulceration in the lining of the anal canal is termed a(n):

anal fissure. Explanation: Fissures are usually caused by the trauma of passing a large, firm stool or from persistent tightening of the anal canal secondary to stress or anxiety (leading to constipation). An anorectal abscess is an infection in the pararectal spaces. An anal fistula is a tiny, tubular, fibrous tract that extends into the anal canal from an opening located beside the anus. A hemorrhoid is a dilated portion of vein in the anal canal.

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

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

A patient is not having daily bowel movements and has begun taking a laxative for this problem. What should the nurse educate the patient about regarding laxative use?

Laxatives should not be routinely taken due to destruction of nerve endings in the colon. Explanation: Laxative abuse, particularly the anthracene derivatives such as senna and cascara, can lead to destruction of the nerves of the colon that are essential for normal peristalsis (Apau, 2010a).

Diet modifications for patient diagnosed with chronic inflammatory bowel disease include which of the following?

Low residue Explanation: Oral fluids and a low-residue, high-protein, high-calorie diet with supplemental vitamin therapy and iron replacement are prescribed to meet the nutritional needs, reduce inflammation, and control pain and diarrhea.

The nurse is admitting a patient with a diagnosis of diverticulitis and assesses that the patient has a boardlike abdomen, no bowel sounds, and complains of severe abdominal pain. What is the nurse's first action?

Notify the physician. Explanation: Abdominal pain, a rigid boardlike abdomen, loss of bowel sounds, and signs and symptoms of shock occur with peritonitis. Peritonitis is typically a life-threatening emergency that requires prompt surgical intervention, and typically involves postoperative critical care monitoring due to the risk of sepsis, organ failure, and subsequent infections; thus, the nurse should notify the physician.

A nurse is interviewing a client about his past medical history. Which preexisting condition may lead the nurse to suspect that a client has colorectal cancer?

Polyps Explanation: Colorectal polyps are common with colon cancer. Duodenal ulcers and hemorrhoids aren't preexisting conditions of colorectal cancer. Weight loss — not gain — is an indication of colorectal cancer.

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. Explanation: 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 nurse is caring for a client who has experienced an acute exacerbation of Crohn's disease. Which statement best indicates that the disease process is under control?

The client exhibits signs of adequate GI perfusion. Explanation: Adequate GI perfusion can be maintained only if Crohn's disease is controlled. If the client experiences acute, uncontrolled episodes of Crohn's disease, impaired GI perfusion may lead to a bowel infarction. Positive self-image, a manageable level of discomfort, and intact skin integrity are expected client outcomes, but aren't related to control of the disease.

A client with anorexia complains of constipation. Which of the following nursing measures would be most effective in helping the client reduce constipation?

Assist client to increase dietary fiber. Explanation: The nurse should assist the client to increase the dietary fiber in her 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.

The nurse is performing and documenting the findings of an abdominal assessment. When the nurse hears intestinal rumbling and the client then experiences diarrhea, the nurse documents the presence of which condition?

Borborygmus Explanation: Borborygmus is the intestinal rumbling caused by the movement of gas through the intestines that accompanies diarrhea. Tenesmus refers to ineffectual straining at stool. Azotorrhea refers to excess of nitrogenous matter in the feces or urine. Diverticulitis refers to inflammation of a diverticulum from obstruction (by fecal matter) resulting in abscess formation.

Which statement provides accurate information regarding cancer of the colon and rectum?

Colorectal cancer is the third most common site of cancer in the United States. Explanation: Cancer of the colon and rectum is the third most common site of new cancer cases in the United States. Colon cancer affects more than twice as many people as does rectal cancer (94,700 for colon, 34,700 for rectum). The incidence increases with age (the incidence is highest in people older than 85). Colon cancer occurrence is higher in people with a family history of colon cancer.

The nurse is reviewing the laboratory test results of a client with Crohn's disease. Which of the following would the nurse most likely find?

Negative stool cultures Explanation: Stool cultures fail to reveal an etiologic microorganism or parasite, but occult blood and white blood cells (WBCs) often are found in the stool. Results of blood studies indicate anemia from chronic blood loss and nutritional deficiencies. The WBC count and erythrocyte sedimentation rate may be elevated, confirming an inflammatory disorder. Serum protein and albumin levels may be low because of malnutrition.

Post appendectomy, a nurse should assess the patient for abdominal rigidity and tenderness, fever, loss of bowel sounds, and tachycardia, all clinical signs of:

Peritonitis Explanation: Peritonitis is inflammation of the peritoneum, the serous membrane lining the abdominal cavity and covering the viscera. Peritonitis is typically a life-threatening emergency that requires prompt surgical intervention, and typically involves postoperative critical care monitoring due to the risk of sepsis, organ failure, and subsequent infections.

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. Explanation: 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.
