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

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.

Celiac disease (celiac sprue) is an example of which category of malabsorption?

Mucosal disorders causing generalized malabsorption -Celiac disease (celiac sprue, gluten-sensitive enteropathy) results from a toxic response to the gliadin component of gluten by the surface epithelium of the intestine; eventually, the mucosal villi of the small intestine become denuded and cannot function. Crohn's disease (regional enteritis) and radiation enteritis are other examples of mucosal disorders.

The most conclusive diagnostic aid for Crohn's disease has classically been a barium study of the upper GI tract that shows a "string sign" on an x-ray film of the terminal ileum, indicating the constriction of a segment of intestine.

Red, sensitive skin around the stoma site

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

A nurse is teaching an older adult client about good bowel habits. Which statement by the client indicates to the nurse that additional teaching is required?

"I need to use laxatives regularly to prevent constipation."

Which of the following is considered a bulk-forming laxative?

Metamucil

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 -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.

A client has a 10-year history of Crohn disease and is seeing the physician due to increased diarrhea and fatigue. What is the recommended dietary approach to treat Crohn disease?

dietary approach varies

An older adult client in a long-term care facility is concerned about bowel regularity. During a client education session, the nurse reinforces the medically acceptable definition of "regularity." What is the actual measurement of "regular"?

stool consistency and client comfort -Normal bowel patterns range from three bowel movements per day to three bowel movements per week. 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.

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.

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.

The nurse is monitoring a client's postoperative course after an appendectomy. The nurse's assessment reveals that the client has vomited, has abdominal tenderness and rigidity, and has tachycardia. The nurse reports to the physician that the client has signs/symptoms of which complication?

Peritonitis -The nurse should report to the physician that the client has signs/symptoms of peritonitis. Signs/symptoms of a pelvic abscess include anorexia, chills, fever, diaphoresis, and diarrhea. Signs/symptoms of an ileus include absent bowel sounds, nausea, and abdominal distention. Signs/symptoms of hemorrhage include tachycardia, hypotension, anxiety, and bleeding.

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.

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 is reporting problems with constipation. What dietary suggestion can the nurse inform the client may help facilitate the passage of stool?

Increase dietary fiber.

The instructor is teaching a group of students about irritable bowel syndrome (IBS) and antidiarrheal agents, the instructor determines that the teaching was effective when the students identify which of the following as an example of an antidiarrheal agent commonly administered for IBS?

Loperamide -Loperamide is an opiate-related antidiarrheal agent. Lubiprostone is used to treat constipation; it activates chloride channels in the gastrointestinal tract to increase gastrointestinal transit. Dicyclomine, a smooth muscle antispasmodic agent, is used to treat pain accompanying IBS. Peppermint oil may also be taken to ease discomfort.

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.

A surgeon is discussing surgery with a client diagnosed with colon cancer. The client is visibly shaken over the possibility of a colostomy. Based on the client's response, the surgeon should collaborate with which health team member?

Enterostomal nurse

A nurse is assessing a client and obtains the following findings: abdominal discomfort, mild diarrhea, blood pressure of 100/80 mm Hg, pulse rate of 88 beats/minute, respiratory rate of 20 breaths/minute, temperature 100° F (37.8° C). What diagnosis will the nurse suspect for this client?

inflammatory bowel disease (IBD) - IBD is a collective term for several GI inflammatory diseases with unknown causes. The most prominent sign of IBD is mild diarrhea, which sometimes is accompanied by fever and abdominal discomfort. Colorectal cancer is usually diagnosed after the client complains of bloody stools; the client will rarely have abdominal discomfort. A client with diverticulitis commonly states he has chronic constipation with occasional diarrhea, nausea, vomiting, and abdominal distention. Jaundice, coagulopathies, edema, and hepatomegaly are common signs of liver failure.

A resident at a long-term care facility lost the ability to swallow following a stroke 4 years ago. The client receives nutrition via a PEG tube, has adapted well to the tube feedings, and remains physically and socially active. Occasionally, the client develops constipation that requires administration of a laxative to restore regular bowel function. What is the most likely cause of this client's constipation?

lack of free water intake

A nursing assessment of a client with peritonitis reveals hypotension, tachycardia, and signs and symptoms of dehydration. What else would the nurse expect to find?

severe abdominal pain with direct palpation or rebound tenderness -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 (i.e., appendicitis, diverticulitis, ulcerative colitis, 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 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.

The nurse is caring for a patient who has malabsorption syndrome with an undetermined cause. What procedure will the nurse assist with that is the best diagnostic test for this illness?

Endoscopy with mucosal biopsy -Endoscopy with biopsy of the mucosa is the best diagnostic tool for malabsorption syndrome.

The nurse is assessing a client for constipation. To identify the cause of constipation, the nurse should begin by reviewing the client's:

usual pattern of elimination.

Acyclovir (Zovirax) is often given to clients with

viral anorectal infections.

A client presents to the emergency room with a possible diagnosis of appendicitis. The health care provider asks the nurse to assess for tenderness at McBurney's point. The nurse knows to palpate which area?

Between the umbilicus and the anterior superior iliac spine

Which drug is considered a stimulant laxative?

Bisacodyl

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

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

Breast

A nurse is performing focused assessment on her clients. She expects to hear hypoactive bowel sounds in a client with:

paralytic ileus.

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 change in bowel habits - 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.

Which of the following would a nurse expect to assess in a client with peritonitis?

Board-like abdomen -The client with peritonitis would typically exhibit a rigid, board-like abdomen, with absent bowel sounds, elevated pulse rate, and rapid, shallow respirations.

A patient visited a nurse practitioner because he had diarrhea for 2 weeks. He described his stool as large and greasy. The nurse knows that this description is consistent with a diagnosis of:

Intestinal malabsorption.

A client is admitted with a diagnosis of acute appendicitis. When assessing the abdomen, the nurse would expect to find rebound tenderness at which location?

Right lower quadrant -The pain of acute appendicitis localizes in the right lower quadrant (RLQ) at McBurney's point, an area midway between the umbilicus and the right iliac crest. Often, the pain is worse when manual pressure near the region is suddenly released, a condition called rebound tenderness.

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 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.

A client is admitted to the emergency department with reports right lower quadrant pain. Blood specimens are drawn and sent to the laboratory. Which laboratory finding should be reported to the health care provider immediately?

White blood cell (WBC) count 22.8/mm3

Doxycycline (Vibramycin) and penicillin (penicillin G) are drugs of choice for

bacterial infections.

Psyllium hydrophilic mucilloid is a

bulk-forming agent.

Colorectal polyps are common with

colon cancer.

Mineral oil is a

lubricant.

Borborygmus is a

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

Which term refers to a protrusion of the intestine through a weakened area in the abdominal wall?

Hernia -A hernia is a protrusion of intestine through a weakened area in the abdominal muscle or wall. A tumor that extends into the intestinal lumen, or a tumor outside the intestine, causes pressure on the wall of the intestine. Volvulus occurs when the bowel twists and turns on itself. An adhesion occurs when loops of intestine become adherent to areas that heal slowly or scar after abdominal surgery.

A patient diagnosed with IBS is advised to eat a diet that is:

High in fiber. - A high-fiber diet is prescribed to control diarrhea and constipation and is recommended for patients with IBS.

A client with Crohn's disease is losing weight. For which reason will the nurse anticipate the client being prescribed parenteral nutrition?

Impaired ability to absorb food -A client with Crohn's disease will have an impaired ability to ingest or absorb food orally or enterally. Clients with severe burns, malnutrition, short-bowel syndrome, AIDS, sepsis, and cancer would need parenteral nutrition because of insufficient oral intake. Unwillingness to ingest nutrients orally would cause a client with a major psychiatric illness to need parenteral nutrition. Prolonged surgical nutritional needs such as what occurs after extensive bowel surgery or acute pancreatitis would necessitate the need for parenteral nutrition.

The nurse is caring for an older adult patient experiencing fecal incontinence. When planning the care of this patient, what should the nurse designate as a priority goal?

Maintaining skin integrity

The nurse in an extended-care facility reports that a resident has clinical manifestations of fecal incontinence. The health care provider orders a diagnostic study to rule out inflammation. Which study will the nurse prepare the client for?

Flexible sigmoidoscopy

A client has a 3 lumen central line inserted into the subclavian vein for parenteral nutrition. Which approach will the nurse take to maintain patency?

Flush each port with diluted heparin in a 10 mL syringe once a shift.

The nurse is caring for a client with an ileostomy because of inflammatory bowel disease. Which assessment findings indicate to the nurse that the ileostomy is functioning as expected? Select all that apply.

- Stoma is pink and shiny - Continuous liquid flows from the stoma

Medical management of a patient with peritonitis includes fluid, electrolyte, and colloid replacement. The nurse knows to prepare the initial, most appropriate intravenous solution. Which of the following is the correct solution?

0.9% NS -The administration of several liters of an isotonic solution is immediately prescribed. Hypovolemia occurs because massive amounts of fluid and electrolytes move from the intestinal lumen into the peritoneal cavity and deplete the fluid in the vascular space.

The nurse is assisting a client to drain his continent ileostomy (Kock pouch). The nurse should insert the catheter how far through the nipple/valve?

2 in. -The nurse should insert the lubricated catheter about 2 inches (5 cm) through the nipple/valve. Please refer to the section on care of ileostomy.

Which client would be at greatest risk for the development of an anorectal fistula?

A 35-year-old female with Crohn's disease -Clients with Crohn's disease have an increased risk for the development of anorectal abscesses and anorectal fistulae. Diverticulosis, irritable bowel syndrome, and colon polyps are not typically associated with anorectal fistulae.

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 nurse is caring for a client admitted with symptoms of an anorectal infection; cultures indicate that the client has a viral infection. The nurse should anticipate the administration of what drug?

Acyclovir

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 -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 preparing a client for a test that involves inserting a thick barium paste into the rectum with radiographs taken as the client expels the barium. What test will the nurse prepare the client for?

Defecography -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.

Which is one of the primary symptoms of irritable bowel syndrome (IBS)?

Diarrhea - The primary symptoms of IBS include constipation, diarrhea, or a combination of both. Pain, bloating, and abdominal distention often accompany changes in bowel pattern.

A nurse is caring for a client with cardiac disease. The client asks the nurse which medication is best for help with regular bowel movements. What is the best response by the nurse?

Docusate

The nurse is conducting discharge teaching for a client with diverticulosis. Which instruction should the nurse include in the teaching?

Drink 8 to 10 glasses of fluid daily.

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

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.

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.

A client suspected of having colorectal cancer requires which diagnostic study to confirm the diagnosis?

Sigmoidoscopy -Used to visualize the lower GI tract, sigmoidoscopy and proctoscopy aid in the detection of two-thirds of all colorectal cancers. Stool Hematest detects blood, which is a sign of colorectal cancer; however, the test doesn't confirm the diagnosis. CEA may be elevated in colorectal cancer but isn't considered a confirming test. An abdominal CT scan is used to stage the presence of colorectal cancer.

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 who has undergone colostomy surgery is experiencing constipation. Which intervention should a nurse consider for such a client?

Suggest fluid intake of at least 2 L/day - The nurse should suggest a fluid intake of at least 2 L/day to help the client avoid constipation. The nurse should also offer prune or apple juice because they promote elimination. The nurse should encourage the client to eat regular meals. Dieting or fasting can decrease stool volume and slow elimination. The nurse should instruct the client to keep a record of food intake in case of diarrhea, because this helps identify specific foods that irritate the gastrointestinal tract.

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.

Which is a true statement regarding regional enteritis (Crohn's disease)?

The clusters of ulcers take on a cobblestone appearance.

Which is a true statement regarding regional enteritis (Crohn's disease)?

The clusters of ulcers take on a cobblestone appearance. -The clusters of ulcers take on a cobblestone appearance. It is characterized by remissions and exacerbations. The pain is located in the lower right quadrant. The lesions are not in continuous contact with one another and are separated by normal tissue.

A nurse is preparing to provide care for a client whose exacerbation of ulcerative colitis has required hospital admission. During an exacerbation of this health problem, the nurse would anticipate that the client's stools will have what characteristics?

Watery with blood and mucus -The predominant symptoms of ulcerative colitis are diarrhea and abdominal pain. Stools may be bloody and contain mucus. Stools are not hard, dry, tarry, black or fatty in clients who have ulcerative colitis.

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

anal fissure. -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.

Metamucil is a

bulk-forming laxative.

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.

Magnesium hydroxide is a

saline agent.

Milk of Magnesia is classified as a

saline agent.

Bisacodyl is a

stimulant laxative.

The nurse is irrigating a client's colostomy when the client begins to report cramping. What is the appropriate action by the nurse?

Clamp the tubing and allow client to rest.

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.

The nurse is comparing Crohn's disease (regional enteritis) with ulcerative colitis. Which of the following describes Crohn's disease?

Its course is prolonged and variable

After assessing a client with peritonitis, how would the nurse most likely document the client's bowel sounds?

Absent -Since lack of bowel motility typically accompanies peritonitis, bowel sounds are absent. Therefore, the nurse will not observe mild, high-pitched, or hyperactive bowel sounds.

What is the most common cause of small-bowel obstruction?

Adhesions -Adhesions are scar tissue that forms as a result of inflammation and infection. Adhesions are the most common cause of small-bowel obstruction, followed by tumors, Crohn's disease, and hernias. Other causes include intussusception, volvulus, and paralytic ileus.

When preparing a client for a hemorrhoidectomy, the nurse should take which action?

Administer an enema as ordered. -When preparing a client for a hemorrhoidectomy, the nurse should administer an enema, as ordered, and record the results. After surgery, the client may require antibiotics and analgesics.

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

Assist client to increase dietary fiber.

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

Borborygmus -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.

A patient is admitted to the hospital after not having had a bowel movement in several days. The nurse observes the patient is having small liquid stools, a grossly distended abdomen, and abdominal cramping. What complication can this patient develop related to this problem?

Bowel perforation

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.

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. -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 having a diagnostic workup for reports of frequent diarrhea, right lower abdominal pain, and weight loss. The nurse is reviewing the results of the barium study and notes the presence of "string sign." What does the nurse understand that this is significant of?

Crohn's disease -The most conclusive diagnostic aid for Crohn's disease has classically been a barium study of the upper GI tract that shows a "string sign" on an x-ray film of the terminal ileum, indicating the constriction of a segment of intestine.

An older adult client seeks help for chronic constipation. What factor related to aging can cause constipation in elderly clients?

Decreased abdominal strength -Decreased abdominal strength, muscle tone of the intestinal wall, and motility all contribute to chronic constipation in the elderly. A decrease in hydrochloric acid causes a decrease in absorption of iron and vitamin B12, whereas an increase in intestinal bacteria actually causes diarrhea.

The nurse is performing a community screening for colorectal cancer. Which characteristic should the nurse include in the screening?

Familial polyposis

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

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.

A client reports severe pain and bleeding while having a bowel movement. Upon inspection, the health care provider notes a linear tear in the anal canal tissue. The client is diagnosed with a:

fissure

Dulcolax is a

stimulant.

A client underwent a continent ileostomy. Within which time frame should the client expect to empty the reservoir?

Every 4 to 6 hours -The length of time between drainage periods is gradually increased until the reservoir needs to be drained only every 4 to 6 hours and irrigated once each day. This prevents the accumulating effluent from spilling or causing infection.

A client has symptoms suggestive of peritonitis. Nursing management would not include:

limiting analgesics to avoid the formation of paralytic ileus. -Analgesics such as meperidine or IV morphine sulfate are ordered to relieve pain and promote rest. Because hypovolemia can occur from fluids leaking into the peritoneal cavity, input and output are monitored closely to assist in determining fluid replacement. A nasogastric tube is used to relieve abdominal distention by suctioning the accumulated gas and stagnant upper GI fluids. If hypovolemia is present, renal perfusion can become decreased, requiring close monitoring.

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

Polyps
