NSG 330 Ch 50- Management of Biliary Disorders

A patients assessment and diagnostic testing are suggestive of acute pancreatitis. When the nurse is performing the health interview, what assessment questions address likely etiologic factors? Select all that apply.

How many alcoholic drinks do you typically consume in a week? Have you ever been diagnosed with gallstones? Eighty percent of patients with acute pancreatitis have biliary tract disease such as gallstones or a history of long-term alcohol abuse. Diabetes, high-fat consumption, and cystic fibrosis are not noted etiologic factors.

A nurse is preparing a plan of care for a patient with pancreatic cysts that have necessitated drainage through the abdominal wall. What nursing diagnosis should the nurse prioritize?

Impaired Skin Integrity While each of the diagnoses may be applicable to a patient with pancreatic drainage, the priority nursing diagnosis is Impaired Skin Integrity. The drainage is often perfuse and destructive to tissue because of the enzyme contents. Nursing measures must focus on steps to protect the skin near the drainage site from excoriation. The application of ointments or the use of a suction apparatus protects the skin from excoriation.

A patients abdominal ultrasound indicates cholelithiasis. When the nurse is reviewing the patients laboratory studies, what finding is most closely associated with this diagnosis?

Increased bilirubin If the flow of blood is impeded, bilirubin, a pigment derived from the breakdown of red blood cells, does not enter the intestines. As a result, bilirubin levels in the blood increase. Cholesterol, BUN, and alkaline phosphatase levels are not typically affected.

A nurse is caring for a patient with gallstones who has been prescribed ursodeoxycholic acid (UDCA). The patient askshow this medicine is going to help his symptoms. The nurse should be aware of what aspect of this drugs pharmacodynamics?

It inhibits the synthesis and secretion of cholesterol. UDCA acts by inhibiting the synthesis and secretion of cholesterol, thereby desaturating bile. UDCA does not directly inhibit either the synthesis or secretion of bile or amylase.

A nurse is caring for a client who was admitted with pain, tenderness, and rigidity of the upper right abdomen, suggesting a gall bladder issue. The client has also been experiencing nausea and vomiting for the past 3 days. The admitting service is planning for tests to be conducted in the morning. Complete the table of diagnostics by choosing from the list of implications for testing.

Laboratory Assessments- Cholesterol is elevated in biliary obstruction. Ultrasonography- It is used to visualize calculi in the gallbladder. Cholescintigraphy- The radioactive dye allows for visualization of the biliary tract. Explanation: Laboratory assessments such as cholesterol levels are used to identify the high levels of cholesterol that contribute to the cholesterol stones. Acidosis (low pH) is not used to diagnosis gall bladder conditions but to identify acid-base imbalances. Potassium is an electrolyte and is not elevated or decreased with the presence of gallstones. An ultrasound or sonography is a high-frequency sound used to produce images of the soft tissue of the gallbladder. Ultrasound can identify a mass, but it does not provide the information needed to determine whether the mass is benign or malignant. The ultrasound does not require sedation; the client is usually awake during the procedure. Cholescintigraphy has been used successfully to diagnosis acute cholecystitis or blockage of a bile duct. In this procedure, a radioactive agent is administered intravenously and then the biliary tract is scanned and images of the gallbladder and biliary tract are obtained. This procedure is more expensive, takes longer to perform and exposes the client to radiation. This procedure does not involve x-rays or high-frequency sound.

A patient with ongoing back pain, nausea, and abdominal bloating has been diagnosed with cholecystitis secondary to gallstones. The nurse should anticipate that the patient will undergo what intervention?

Laparoscopic cholecystectomy Most of the nonsurgical approaches, including lithotripsy and dissolution of gallstones, provide only temporary solutions to gallstone problems and are infrequently used in the United States. Cholecystectomy is the preferred treatment

A patient with a cholelithiasis has been scheduled for a laparoscopic cholecystectomy. Why is laparoscopic cholecystectomy preferred by surgeons over an open procedure?

Laparoscopic cholecystectomy poses fewer surgical risks than an open procedure. Open surgery has largely been replaced by laparoscopic cholecystectomy (removal of the gallbladder through a small incision through the umbilicus). As a result, surgical risks have decreased, along with the length of hospital stay and the long recovery period required after standard surgical cholecystectomy. Both approaches allow for removal of the entire gallbladder and must be performed under general anesthetic in an operating theater

Clinical manifestations of common bile duct obstruction include all of the following except:

Light-colored urine Explanation: The excretion of the bile pigments by the kidneys gives the urine a very dark color. The feces, no longer colored with bile pigments, are grayish, like putty, or clay-colored. The symptoms may be acute or chronic. Epigastric distress, such as fullness, abdominal distention, and vague pain in the right upper quadrant of the abdomen, may occur. If it goes untreated jaundice and pruritus can occur.

A nurse is providing discharge education to a patient who has undergone a laparoscopic cholecystectomy. During the immediate recovery period, the nurse should recommend what foods?

Low-fat foods high in proteins and carbohydrates The nurse encourages the patient to eat a diet that is low in fats and high in carbohydrates and proteins immediately after surgery. There is no specific need to increase fiber or avoid purines. A low-residue diet is not indicated.

A home health nurse is caring for a patient discharged home after pancreatic surgery. The nurse documents the nursing diagnosis Risk for Imbalanced Nutrition: Less than Body Requirements on the care plan based on the potential complications that may occur after surgery. What are the most likely complications for the patient who has had pancreatic surgery?

Malabsorption and hyperglycemia The nurse arrives at this diagnosis based on the complications of malabsorption and hyperglycemia. These complications often lead to the need for dietary modifications. Pancreatic enzyme replacement, a low-fat diet, and vitamin supplementation often are also required to meet the patients nutritional needs and restrictions. Electrolyte imbalances often accompany pancreatic disorders and surgery, but the electrolyte levels are more often deficient than excessive. Hemorrhage is a complication related to surgery, but not specific to the nutritionally based nursing diagnosis. Weight loss is a common complication, but hypoglycemia is less likely

The nurse is caring for a patient with acute pancreatitis. The patient has an order for an anticholinergic medication. The nurse explains that the patient will be receiving that medication for what reason?

To reduce gastric and pancreatic secretions Explanation: Anticholinergic medications reduce gastric and pancreatic secretion.

A nurse is caring for a client admitted with acute pancreatitis. Which nursing action is most appropriate for a client with this diagnosis?

Withholding all oral intake, as ordered, to decrease pancreatic secretions Explanation: The nurse should withhold all oral intake to suppress pancreatic secretions, which may worsen pancreatitis. Pain relief may require parenteral opioids such as morphine, fentanyl (Sublimaze), or hydromorphone (Dilaudid). No clinical evidence supports the use of meperidine for pain relief in pancreatitis, and, in fact, accumulation of its metabolites can cause CNS irritability and possibly seizures. Pancreatitis places the client at risk for fluid volume deficit from fluid loss caused by increased capillary permeability. Therefore, this client needs fluid resuscitation, not fluid restriction. A client with pancreatitis is most comfortable lying on the side with knees flexed.

The nurse instructs a client on care at home after a laparoscopic cholecystectomy. Which client statement indicates that teaching has been effective?

"I should wash the site with mild soap and water." Explanation: After a laparoscopic cholecystectomy, the client should be instructed about pain management, activity and exercise, wound care, nutrition, and follow-up care. The client should be directed to wash the puncture site with mild soap and water when caring for the wound. When resuming activity, the client should be instructed to drive after 3 or 4 days, take a shower or bath after 1 or 2 days, and begin light exercise such as walking immediately.

A nurse cares for an older adult client and teaches the client about age-related changes of the biliary tract. What statements will the nurse include when discussing age-related changes that occur in the pancreas of the older adult? Select all that apply.

"The pancreas develops fibrous material with age." "The pancreas develops fatty deposits with age." "The pancreas decreases secretion of enzymes with age." "The pancreas decreases bicarbonate secretion with age." Explanation: Age-related changes to the pancreas include: the development of fibrous material and fatty deposits, as well as decreased secretion of both pancreatic enzymes and bicarbonate. The pancreas remains the same size as the client ages and atrophy is not a normal age-related finding.

Pharmacologic therapy frequently is used to dissolve small gallstones. It takes about how many months of medication with UDCA or CDCA for stones to dissolve?

6 to 12 Explanation: Ursodeoxycholic acid (UDCA [URSO, Actigall]) and chenodeoxycholic acid (chenodiol or CDCA [Chenix]) have been used to dissolve small, radiolucent gallstones composed primarily of cholesterol. Six to 12 months of therapy are required in many clients to dissolve stones, and monitoring of the client for recurrence of symptoms or occurrence of side effects (e.g., GI symptoms, pruritus, headache) is required during this time.

This example of cholesterol gallstones (left side of picture) is the result of decreased bile acid synthesis and increased cholesterol synthesis in the liver, which in turn, form stones. Cholesterol stones account for what percentage of cases of gallbladder disease in the United States?

75% Explanation: Cholesterol stones account for approximately 75% of cases of gallbladder disease in the United States.

A nurse who provides care in a walk-in clinic assesses a wide range of individuals. The nurse should identify which of the following patients as having the highest risk for chronic pancreatitis?

A 39-year-old man with chronic alcoholism Excessive and prolonged consumption of alcohol accounts for approximately 70% to 80% of all cases of chronic pancreatitis.

A client is evaluated for severe pain in the right upper abdominal quadrant, which is accompanied by nausea and vomiting. The physician diagnoses acute cholecystitis and cholelithiasis. For this client, which nursing diagnosis takes top priority?

Acute pain related to biliary spasms Explanation: The chief symptom of cholecystitis is abdominal pain or biliary colic. Typically, the pain is so severe that the client is restless and changes positions frequently to find relief. Therefore, the nursing diagnosis of Acute pain related to biliary spasms takes highest priority. Until the acute pain is relieved, the client can't learn about prevention, may continue to experience anxiety, and can't address nutritional concerns.

A nurse is teaching a client and the client's family about chronic pancreatitis. Which are the major causes of chronic pancreatitis?

Alcohol consumption and smoking Explanation: Alcohol consumption in Western societies is a major factor in the development of chronic pancreatitis, as is smoking. Because heavy drinkers usually smoke, it is difficult to separate the effects of the alcohol abuse and smoking. Malnutrition is a major cause of chronic pancreatitis worldwide, but alcohol consumption is more commonly the cause in Western societies. Caffeine consumption is not related to acute pancreatitis. Acute hepatitis does not usually lead to chronic pancreatitis unless complications develop.

A patient has had a laparoscopic cholecystectomy. The patient is now complaining of right shoulder pain. What should the nurse suggest to relieve the pain?

Application of heat 15 to 20 minutes each hour If pain occurs in the right shoulder or scapular area (from migration of the CO2 used to insufflate the abdominal cavity during the procedure), the nurse may recommend use of a heating pad for 15 to 20 minutes hourly, walking, and sitting up when in bed. Aspirin would constitute a risk for bleeding.

A community health nurse is caring for a patient whose multiple health problems include chronic pancreatitis. During the most recent visit, the nurse notes that the patient is experiencing severe abdominal pain and has vomited 3 times in the past several hours. What is the nurses most appropriate action?

Arrange for the patient to be transported to the hospital. Chronic pancreatitis is characterized by recurring attacks of severe upper abdominal and back pain, accompanied by vomiting. The onset of these acute symptoms warrants hospital treatment. Pancreatic enzymes are not indicated and an NG tube would not be inserted in the home setting. Patient education is a later priority that may or may not be relevant.

A nurse is creating a care plan for a patient with acute pancreatitis. The care plan includes reduced activity. What rationale for this intervention should be cited in the care plan?

Bed rest lowers the metabolic rate and reduces enzyme production The acutely ill patient is maintained on bed rest to decrease the metabolic rate and reduce the secretion of pancreatic and gastric enzymes. Staying in bed does not release energy from the body to fight the disease.

A patient returns to the floor after a laparoscopic cholecystectomy. The nurse should assess the patient for signs and symptoms of what serious potential complication of this surgery?

Bile duct injury The most serious complication after laparoscopic cholecystectomy is a bile duct injury. Patients do not face a risk of diabetic coma. A decubitus ulcer is unlikely because immobility is not expected. Evisceration is highly unlikely, due to the laparoscopic approach.

A client who had developed jaundice 2 months earlier is brought to the ED after attending a party and developing excruciating pain that radiated over the abdomen and into the back. Upon assessment, which additional symptom would the nurse expect this client to have?

Bile-stained vomiting Explanation: Nausea and vomiting are common in acute pancreatitis. The emesis is usually gastric in origin but may also be bile stained. Fever, jaundice, mental confusion, and agitation may also occur.

The nurse is caring for a patient who has just returned from the ERCP removal of gallstones. The nurse should monitor the patient for signs of what complications?

Bleeding and perforation Following ERCP removal of gallstones, the patient is observed closely for bleeding, perforation, and the development of pancreatitis or sepsis. Blood sugar alterations, gangrene, peritonitis, and acidosis are less likely complications.

A student nurse is caring for a patient who has a diagnosis of acute pancreatitis and who is receiving parenteral nutrition. The student should prioritize which of the following assessments?

Blood glucose levels In addition to administering enteral or parenteral nutrition, the nurse monitors serum glucose levels every 4 to 6 hours. Output should be monitored but in most cases it is not more important than serum glucose levels. A patient on parenteral nutrition would have no oral intake to monitor. Blood sugar levels are more likely to be unstable than indicators of renal function.

A nurse is reviewing the health care provider orders for a client admitted with acute pancreatitis. The health care provider has ordered intravenous calcium chloride infusions for the client. What does the nurse understand is the reason for this order?

Calcium binds to fatty acids when auto digestion of the pancreas occurs. Explanation: Hypocalcemia is a potential problem with acute pancreatitis because calcium binds to fatty acids when auto digestion of the pancreas occurs.

The nurse is caring for a client with a biliary disorder who has an elevated amylase level. If this elevation correlates to dysfunction, which body process does the nurse recognize may be impaired?

Carbohydrate digestion Explanation: Amylase is a pancreatic enzyme involved in the breakdown and digestion of carbohydrates. Trypsin aids in the digestion of proteins. Lipase aids in the digestion of fats.

A client has a tumor of the head of the pancreas. What clinical manifestations will the nurse assess? Select all that apply.

Clay-colored stools Dark urine Jaundice Explanation: Sixty to eighty percent of pancreatic tumors occur in the head of the pancreas. Tumors in this region obstruct the common bile duct. The obstructed flow of bile produces jaundice, clay-colored stools, and dark urine. Malabsorption of nutrients and fat-soluble vitamins may result if the tumor obstructs the entry of bile to the gastrointestinal tract. Abdominal discomfort or pain and pruritus may be noted, along with anorexia, weight loss, and malaise. If these signs and symptoms are present, cancer of the head of the pancreas is suspected. Persistent hiccups are seen with stomach and bowel diseases.

The nurse is caring for a client recovering from acute pancreatitis. Which menu item should the nurse remove from the client's breakfast tray?

Coffee Explanation: Post-acute management of the client with acute pancreatitis includes the introduction of solid food. Oral feedings that are low in fat and protein are gradually initiated. Caffeine is eliminated from the diet and therefore coffee, which contains caffeine, should be removed from the client's breakfast tray. Even decaffeinated coffee has a small amount of caffeine but could serve as a compromise for chronic coffee drinkers. The other food items are appropriate for the client.

A nurse cares for a client who is post op open cholecystectomy. Upon assessment, the nurse notes the client's abdomen feels firm to palpation. What is the nurse's priority action?

Contact the health care provider Explanation: A client who is post op from open abdominal surgery is at risk for internal bleeding, which may manifest as rigidity of the abdomen. The nurse's priority is to contact the health care provider. Additional interventions will be necessary but contacting the health care provider is priority.

A 70-year-old client is admitted with acute pancreatitis. The nurse understands that the mortality rate associated with acute pancreatitis increases with advanced age and attributes this to which gerontologic consideration associated with the pancreas?

Decreases in the physiologic function of major organs Explanation: Acute pancreatitis affects people of all ages, but the mortality rate associated with acute pancreatitis increases with advancing age. The pattern of complications changes with age. Younger clients tend to develop local complications; the incidence of multiple organ failure increases with age, possibly as a result of progressive decreases in physiologic function of major organs with increasing age.

What is the most appropriate nursing diagnosis for the client with acute pancreatitis?

Deficient fluid volume Explanation: Clients with acute pancreatitis often experience deficient fluid volume, which can lead to hypovolemic shock. Vomiting, hemorrhage (in hemorrhagic pancreatitis), and plasma leaking into the peritoneal cavity may cause the volume deficit. Hypovolemic shock will cause a decrease in cardiac output. Gastrointestinal tissue perfusion will be ineffective if hypovolemic shock occurs, but this wouldn't be the primary nursing diagnosis.

Increased appetite and thirst may indicate that a client with chronic pancreatitis has developed diabetes mellitus. Which of the following explains the cause of this secondary diabetes?

Dysfunction of the pancreatic islet cells Explanation: Diabetes mellitus resulting from dysfunction of the pancreatic islet cells is treated with diet, insulin, or oral antidiabetic agents. The hazard of severe hypoglycemia with alcohol consumption is stressed to the client and family. When secondary diabetes develops in a client with chronic pancreatitis, the client experiences increased appetite, thirst, and urination. A standard treatment with pancreatitis is to make the client NPO. The dysfunction is related to the pancreas, not the liver.

A patient has been treated in the hospital for an episode of acute pancreatitis. The patient has acknowledged the role that his alcohol use played in the development of his health problem, but has not expressed specific plans for lifestyle changes after discharge. What is the nurses most appropriate response?

Encourage the patient to connect with a community-based support group. After the acute attack has subsided, some patients may be inclined to return to their previous drinking habits. The nurse provides specific information about resources and support groups that may be of assistance in avoiding alcohol in the future. Referral to Alcoholics Anonymous as appropriate or other support groups is essential. The patient already has an understanding of the effects of alcohol, and follow-up appointments will not necessarily result in lifestyle changes. Social work and spiritual care may or may not be beneficial.

A patient is receiving care in the intensive care unit for acute pancreatitis. The nurse is aware that pancreatic necrosis is a major cause of morbidity and mortality in patients with acute pancreatitis. Consequently, the nurse should assess for what signs or symptoms of this complication?

Fever, increased heart rate and decreased blood pressure Pancreatic necrosis is a major cause of morbidity and mortality in patients with acute pancreatitis because of resulting hemorrhage, septic shock, and multiple organ dysfunction syndrome (MODS). Signs of shock would include hypotension, tachycardia and fever. Each of the other listed changes in status warrants intervention, but none is clearly suggestive of an onset of pancreatic necrosis.

When the nurse is caring for a patient with acute pancreatitis, what intervention can be provided in order to prevent atelectasis and prevent pooling of respiratory secretions?

Frequent changes of positions Explanation: Frequent changes of position are necessary to prevent atelectasis and pooling of respiratory secretions.

A nurse is assisting with serving dinner trays on the unit. Upon receiving the dinner tray for a patient admitted with acute gallbladder inflammation, the nurse will question which of the following foods on the tray?

Fried chicken The diet immediately after an episode of acute cholecystitis is initially limited to low-fat liquids. Cooked fruits, rice or tapioca, lean meats, mashed potatoes, bread, and coffee or tea may be added as tolerated. The patient should avoid fried foods such as fried chicken, as fatty foods may bring on an episode of cholecystitis.

A patient presents to the emergency department (ED) complaining of severe right upper quadrant pain. The patient states that his family doctor told him he had gallstones. The ED nurse should recognize what possible complication of gallstones?

Gangrene of the gallbladder In calculous cholecystitis, a gallbladder stone obstructs bile outflow. Bile remaining in the gallbladder initiates a chemical reaction; autolysis and edema occur; and the blood vessels in the gallbladder are compressed, compromising its vascular supply. Gangrene of the gallbladder with perforation may result. Pancreatitis, atrophy, and cancer of the gallbladder are not plausible complications.

A patient has a recent diagnosis of chronic pancreatitis and is undergoing diagnostic testing to determine pancreatic islet cell function. The nurse should anticipate what diagnostic test?

Glucose tolerance test A glucose tolerance test evaluates pancreatic islet cell function and provides necessary information for making decisions about surgical resection of the pancreas. This specific clinical information is not provided by ERCP, biopsy, or ultrasound.

A client with suspected biliary obstruction due to gallstones reports changes to the color of his stools. Which stool color does the nurse recognize as common to biliary obstruction?

Gray Explanation: A gray-white stool color is common with a biliary obstruction because the stool is no longer colored with bile pigments.

A patient has been scheduled for an ultrasound of the gallbladder the following morning. What should the nurse do in preparation for this diagnostic study?

Have the patient refrain from food and fluids after midnight. An ultrasound of the gallbladder is most accurate if the patient fasts overnight, so that the gallbladder is distended. Contrast and radioactive agents are not used when performing ultrasonography of the gallbladder, as an ultrasound is based on reflected sound waves.

A patient with gallstones has been prescribed ursodeoxycholic acid (UDCA). The nurse understands that additional teaching is needed regarding this medication when the patient states:

I will take this medication for 2 weeks and then gradually stop taking it. Ursodeoxycholic acid (UDCA) has been used to dissolve small, radiolucent gallstones composed primarily of cholesterol. This drug can reduce the size of existing stones, dissolve small stones, and prevent new stones from forming. Six to 12 months of therapy is required in many patients to dissolve stones, and monitoring of the patient is required during this time. The effective dose of medication depends on body weight.

A patient has been diagnosed with acute pancreatitis. The nurse is addressing the diagnosis of Acute Pain Related to Pancreatitis. What pharmacologic intervention is most likely to be ordered for this patient?

IV hydromorphone (Dilaudid) The pain of acute pancreatitis is often very severe and pain relief may require parenteral opioids such as morphine, fentanyl (Sublimaze), or hydromorphone (Dilaudid). There is no clinical evidence to support the use of meperidine for pain relief in pancreatitis. Opioids are preferred over NSAIDs

Which enzyme aids in the digestion of fats?

Lipase Explanation: Lipase is a pancreatic enzyme that aids in the digestion of fats. Amylase aids in the digestion of carbohydrates. Secretin is responsible for stimulating secretion of pancreatic juice. Trypsin aids in the digestion of protein.

A nurse is planning care for a client with acute pancreatitis. Which client outcome does the nurse assign as the highest priority?

Maintaining normal respiratory function Explanation: Airway and breathing are always the priority assessment. Acute pancreatitis produces retroperitoneal edema, elevation of the diaphragm, pleural effusion, and inadequate lung ventilation. Intra-abdominal infection and labored breathing increase the body's metabolic demands, which further decreases pulmonary reserve and can lead to respiratory failure. Maintenance of adequate respiratory function is the priority goal. The other outcomes would also be appropriate for the patient.

A client with acute pancreatitis has been started on total parenteral nutrition (TPN). Which action should the nurse perform after administration of the TPN?

Measure blood glucose concentration every 4 to 6 hours Explanation: Enteral or parenteral nutrition may be prescribed. In addition to administering enteral or parenteral nutrition, the nurse monitors the serum glucose concentration every 4 to 6 hours.

A patient with chronic pancreatitis had a pancreaticojejunostomy created 3 months ago for relief of pain and to restore drainage of pancreatic secretions. The patient has come to the office for a routine postsurgical appointment. The patient is frustrated that the pain has not decreased. What is the most appropriate initial response by the nurse?

Pain relief occurs by 6 months in most patients who undergo this procedure, but some people experience a recurrence of their pain. Pain relief from a pancreaticojejunostomy often occurs by 6 months in more than 85% of the patients who undergo this procedure, but pain returns in a substantial number of patients as the disease progresses. This patient had surgery 3 months ago; the patient has 3 months before optimal benefits of the procedure may be experienced. There is no obvious indication for gallbladder removal and nonadherence is not the most likely factor underlying the pain.

Because clients with pancreatitis cannot tolerate high-glucose concentrations, total parental nutrition (TPN) should be used cautiously with them. Which of the following interventions has shown great promise in the prognosis of clients with severe acute pancreatitis?

Providing intensive insulin therapy Explanation: Intensive insulin therapy (continuous infusion) in the critically ill client has undergone much study and has shown promise in terms of positive client outcomes when compared with intermittent insulin dosing. Glycemic control with normal or near normal blood glucose levels improves client outcomes. Total parental nutrition (TPN) is used carefully in clients with pancreatitis because some clients cannot tolerate a high-glucose concentration, even with insulin coverage. Clients with pancreatitis should not be given high-fat foods because they are difficult to digest. The current recommendation for pain management in this population is parenteral opioids. The nurse should maintain the client in a semi-Fowler's position to reduce pressure on the diaphragm.

A client with pancreatitis is admitted to the medical intensive care unit. Which nursing intervention is most appropriate?

Reserving a site for a peripherally inserted central catheter (PICC) Explanation: Pancreatitis treatment typically involves resting the GI tract by maintaining nothing-by-mouth status. The nurse should reserve a site for placement of a PICC, which enables the client to receive long-term total parenteral nutrition. Clients in the acute stages of pancreatitis also require large volumes of I.V. fluids to compensate for fluid loss.

A nurse is teaching a client about the cause of acute pancreatitis. The nurse evaluates the teaching as effective when the client correctly identifies which condition as a cause of acute pancreatitis?

Self-digestion of the pancreas by its own proteolytic enzymes Explanation: Self-digestion of the pancreas by its own proteolytic enzymes, principally trypsin, causes acute pancreatitis. Of clients with acute pancreatitis, 80% had undiagnosed chronic pancreatitis. Gallstones enter the common bile duct and lodge at the ampulla of Vater, obstructing the flow of pancreatic juice or causing a reflux of bile from the common bile duct into the pancreatic duct, thus activating the powerful enzymes within the pancreas. Normally, these remain in an inactive form until the pancreatic secretions reach the lumen of the duodenum. Activation of the enzymes can lead to vasodilation, increased vascular permeability, necrosis, erosion, and hemorrhage.

A patient is admitted to the unit with acute cholecystitis. The physician has noted that surgery will be scheduled in 4 days. The patient asks why the surgery is being put off for a week when he has a sick gallbladder. What rationale would underlie the nurses response?

Surgery is delayed until the acute symptoms subside Unless the patients condition deteriorates, surgical intervention is delayed just until the acute symptoms subside (usually within a few days). There is no need to delay surgery pending an improvement in nutritional status, and deciding on a laparoscopic approach is not a lengthy process.

A client with acute pancreatitis reports muscle cramping in the lower extremities. What pathophysiology concept represents the reason the client is reporting this?

Tetany related to hypocalcemia Explanation: A client with acute pancreatitis who reports muscle cramping or pain should be suspected of having hypocalcemia and tetany of the muscles. Hypocalcemia may occur in acute pancreatitis because, when auto digestion of the pancreas occurs, calcium binds to fatty acids and calcium is decreased in the blood. This is a potentially life-threatening complication of pancreatitis and needs to be immediately addressed.

The family of a patient in the ICU diagnosed with acute pancreatitis asks the nurse why the patient has been moved to an air bed. What would be the nurses best response?

The bed automatically moves, so shes less likely to develop pressure sores while shes in bed. It is important to turn the patient every 2 hours; use of specialty beds may be indicated to prevent skin breakdown. The rationale for a specialty bed is not related to repositioning, comfort, or ease of movement.

A patient is admitted to the hospital with possible cholelithiasis. What diagnostic test of choice will the nurse prepare the patient for?

Ultrasonography Explanation: Ultrasonography has replaced cholecystography (discussed later) as the diagnostic procedure of choice because it is rapid and accurate and can be used in patients with liver dysfunction and jaundice. It does not expose patients to ionizing radiation.

The nurse knows that the client with cholelithiasis can have a nutritional deficiency. The obstruction of bile flow due to cholelithiasis can interfere with the absorption of

Vitamin A Explanation: Obstruction of bile flow interferes with absorption of the fat-soluble vitamins A, D, E, and K. Clients may exhibit deficiencies of these vitamins if biliary obstruction has been prolonged. Vitamins B6, B12, and C are not fat soluble.

A client with cholelithiasis has a gallstone lodged in the common bile duct. When assessing this client, the nurse expects to note:

yellow sclerae. Explanation: Yellow sclerae are an early sign of jaundice, which occurs when the common bile duct is obstructed. Urine normally is light amber. Circumoral pallor and black, tarry stools don't occur in common bile duct obstruction; they are signs of hypoxia and GI bleeding, respectively.

A client with calculi in the gallbladder is said to have

Cholelithiasis Explanation: Calculi, or gallstones, usually form in the gallbladder from the solid constituents of bile; they vary greatly in size, shape, and composition. Cholecystitis is acute inflammation of the gallbladder. Choledocholithiasis is a gallstone in the common bile duct. Choledochotomy is an incision into the common bile duct.

A client who is 24 hours post op from laparoscopic cholecystectomy calls the nurse and reports pain in the right shoulder. How should the nurse respond to the client's report of symptoms?

"Apply a heating pad to your shoulder for 15 minutes hourly as needed." Explanation: Pain in the right shoulder may occur after laparoscopic cholecystectomy due to migration of the carbon dioxide used to insufflate the abdominal cavity during the procedure. The nurse should instruct the client to apply a heating pad to the shoulder for 15 to 20 minutes every hour as needed for pain relief. The nurse should not instruct the client to take analgesic medication-this is a medical order performed by the health care provider only. This scenario is not life threatening and the client does not need to go to the emergency department. It is also not necessary for the client to place the shoulder in a sling as this is not an injury-related condition.

The nurse is assessing a client admited with suspected pancreatitis. Which question will the nurse prioritize when assessing this client?

"How much alcohol do you consume in a day?" Explanation: Chronic pancreatitis is an inflammatory disorder characterized by progressive destruction of the pancreas. Alcohol consumption in Western societies is the major cause of chronic pancreatitis. Excessive and prolonged consumption of alcohol accounts for approximately 70% to 80% of all cases of chronic pancreatitis. The incidence of pancreatitis is 50 times greater in people with alcoholism than in those who do not abuse alcohol. The type of food (like fried or heavily processed foods) rather than the number of meals eaten each day may contribute to pancreatitis and subsequent flare-ups of the condition. The prescibed use of acetaminophen is not a typical risk factor in pancreatitis and is rare with cases of overdose. The amount and/or lack of exercise is not directly linked to pancreatitis. Risk factors include obesity.

A nurse is preparing a client for endoscopic retrograde cholangiopancreatography (ERCP). The client asks what this test is used for. Which statements by the nurse explains how ERCP can determine the difference between pancreatitis and other biliary disorders? Select all that apply.

"It can evaluate the presence and location of ductal stones and aid in stone removal." "It can assess the anatomy of the pancreas and the pancreatic and biliary ducts." "It can detect unhealthy tissues in the pancreas and assess for abscesses and pseudocysts." Explanation: ERCP can determine the difference between pancreatitis and other biliary disorders and is generally used in chronic pancreatitis. It is particularly useful in diagnosis and treatment of clients who have symptoms after biliary tract surgery, clients with intact gallbladders, and clients for whom surgery is particularly hazardous. It can be used to assist with the removal of stones. ERCP is a useful tool in providing anatomic details about the pancreas and biliary ducts. It can evaluate the presence and location of ductal stones and detect changes in the anatomy of the client with pancreatitis, such as obstruction in the pancreatic duct and tissue necrosis due to premature release of pancreatic enzymes, and assess for abscesses and pseudocysts and atrophy of the glands in the body. ERCP is rarely used in the diagnostic evaluation of acute pancreatitis because the clients is acutely ill; however, it may be valuable in treating gallstone pancreatitis.

A client has a nasogastric (NG) tube for suction and is NPO after a pancreaticoduodenectomy. Which explanation made by the nurse is the major purpose of this treatment?

"The tube allows the gastrointestinal tract to rest." Explanation: Postoperative management of clients who have undergone a pancreatectomy or a pancreaticoduodenectomy is similar to the management of clients after extensive gastrointestinal or biliary surgery. An NG tube with suction and parenteral nutrition allow the gastrointestinal tract to rest while promoting adequate nutrition.

A client discharged after a laparoscopic cholecystectomy calls the surgeon's office reporting severe right shoulder pain 24 hours after surgery. Which statement is the correct information for the nurse to provide to this client?

"This pain is caused from the gas used to inflate your abdominal area during surgery. Sitting upright in a chair, walking, or using a heating pad may ease the discomfort." Explanation: If pain occurs in the right shoulder or scapular area (from migration of the carbon dioxide used to insufflate the abdominal cavity during the procedure), the nurse may recommend using a heating pad for 15 to 20 minutes hourly, sitting up in a bed or chair, or walking.

A patient is diagnosed with mild acute pancreatitis. What does the nurse understand is characteristic of this disorder?

Edema and inflammation Explanation: Mild acute pancreatitis is characterized by edema and inflammation confined to the pancreas. Minimal organ dysfunction is present, and return to normal function usually occurs within 6 months.

A client admitted with severe epigastric abdominal pain radiating to the back is vomiting and reports difficulty breathing. Upon assessment, the nurse determines that the client is experiencing tachycardia and hypotension. Which actions are priority interventions for this client? Select all that apply.

Administer pain-relieving medication Administer electrolytes Administer plasma Assist the client to a semi-Fowler position Explanation: The nurse promptly reports decreased blood pressure (BP) and reduced urine output, which indicate hypovolemia and shock or renal failure. The treatment goals for acute pancreatitis focus on relieving pain, maintaining circulatory and fluid volume, and decreasing the production of pancreatic enzymes. Intravenous replacement of fluid and electrolytes should begin immediately because of the loss of fluid in the body. If hypotension is evident, plasma should be administered to maintain BP within an acceptable range. Fluids are administered intravenously and may be accompanied by infusion of blood or blood products to maintain blood volume and to prevent or treat hypovolemic shock. Low serum calcium and magnesium concentrations may occur and require prompt treatment. The nurse maintains the client in a semi-Fowler position to decrease pressure on the diaphragm by a distended abdomen and to increase respiratory expansion. A low-fat diet, with small frequent meals, should be initiated after control of symptoms; it is not an immediate priority.

A client with a history of alcohol abuse comes to the emergency department and complains of abdominal pain. Laboratory studies help confirm a diagnosis of acute pancreatitis. The client's vital signs are stable, but the client's pain is worsening and radiating to his back. Which intervention takes priority for this client?

Administering morphine I.V. as ordered Explanation: The nurse should address the client's pain issues first by administering morphine I.V. as ordered. Placing the client in a Semi-Fowler's position, maintaining NPO status, and providing mouth care don't take priority over addressing the client's pain issues.

Which foods should be avoided following acute gallbladder inflammation?

Cheese Explanation: The client should avoid eggs, cream, pork, fried foods, cheese, rich dressings, gas-forming vegetables, and alcohol. It is important to remind the client that fatty foods may induce an episode of cholecystitis. Cooked fruits, rice or tapioca, lean meats, mashed potatoes, non-gas-forming vegetables, bread, coffee, or tea may be consumed as tolerated.

Which term most precisely refers to the incision of the common bile duct for removal of stones?

Choledocholithotomy Explanation: Choledocholithotomy refers to incision of the common bile duct for the removal of stones. Cholecystostomy refers to opening and draining the gallbladder. Choledochotomy refers to opening into the common duct. Choledochoduodenostomy refers to anastomosis of the common duct to the duodenum.

A patient has just been diagnosed with chronic pancreatitis. The patient is underweight and in severe pain and diagnostic testing indicates that over 80% of the patients pancreas has been destroyed. The patient asks the nurse why the diagnosis was not made earlier in the disease process. What would be the nurses best response?

Chronic pancreatitis often goes undetected until a large majority of pancreatic function is lost. By the time symptoms occur in chronic pancreatitis, approximately 90% of normal acinar cell function (exocrine function) has been lost. Late detection is not usually attributable to the vagueness of symptoms. The pancreas contributes continually to homeostasis and other organs are unable to perform its physiologic functions.

A patient has been admitted to the hospital for the treatment of chronic pancreatitis. The patient has been stabilized and the nurse is now planning health promotion and educational interventions. Which of the following should the nurse prioritize?

Educating the patient about postdischarge lifestyle modifications The patients lifestyle (especially regarding alcohol use) is a major determinant of the course of chronic pancreatitis. The disease is not often managed by surgery and blood sugar monitoring is not necessarily indicated for every patient after hospital treatment. Transplantation is not an option

A client is admitted to the healthcare facility suspected of having acute pancreatitis and undergoes laboratory testing. Which of the following would the nurse expect to find?

Elevated urine amylase levels Explanation: Elevated serum and urine amylase, lipase, and liver enzyme levels accompany significant pancreatitis. If the common bile duct is obstructed, the bilirubin level is above normal. Blood glucose levels and white blood cell counts can be elevated. Serum electrolyte levels (calcium, potassium, and magnesium) are low.

The patient admitted with acute pancreatitis has passed the acute stage and is now able to tolerate solid foods. What type of diet will increase caloric intake without stimulating pancreatic enzymes beyond the ability of the pancreas to respond?

High-carbohydrate, low-protein, low-fat diet Explanation: The nurse should provide a high-carbohydrate, low-protein, low-fat diet when tolerated. These foods increase caloric intake without stimulating pancreatic secretions beyond the ability of the pancreas to respond.

A nurse is preparing a client for surgery. During preoperative teaching, the client asks where is bile stored. The nurse knows that bile is stored in the:

Gallbladder Explanation: The gallbladder functions as a storage depot for bile.

A patient with pancreatic cancer has been scheduled for a pancreaticoduodenectomy (Whipple procedure). During health education, the patient should be informed that this procedure will involve the removal of which of the following? Select all that apply.

Gallbladder Part of the stomach Duodenum Part of the common bile duct A pancreaticoduodenectomy (Whipple procedure or resection) is used for potentially resectable cancer of the head of the pancreas (Fig. 50-7). This procedure involves removal of the gallbladder, a portion of the stomach, duodenum, proximal jejunum, head of the pancreas, and distal common bile duct. The rectum is not affected.

A patient has been diagnosed with pancreatic cancer and has been admitted for care. Following initial treatment, the nurse should be aware that the patient is most likely to require which of the following?

Hospice care Pancreatic carcinoma has only a 5% survival rate at 5 years regardless of the stage of disease at diagnosis or treatment. As a result, there is a higher likelihood that the patient will require hospice care than physical therapy and rehabilitation.

Which is a gerontological consideration associated with the pancreas?

Increased amount of fibrous material Explanation: An increase in fibrous material and some fatty deposition occurs in the normal pancreas of people older than 70 years of age. There is a decreased rate of pancreatic secretion and decreased bicarbonate output in older adults. Decreased calcium absorption may also occur

A client is scheduled for a cholecystogram for later in the day. What is the nurse's understanding on the diagnostic use of this exam?

It visualizes the gallbladder and bile duct. Explanation: The cholecystogram is a diagnostic imaging test used to visualize the gallbladder and bile duct. The celiac axis arteriography visualizes the liver and pancreas. Ultrasonography shows the sizes of the abdominal organs and detects any masses. The endoscopic retrograde cholangiopancreatography (ERCP) visualizes the biliary structures and pancreas via endoscopy.

A critical care nurse is caring for a client with acute pancreatitis. One potentially severe complication involves the respiratory system. Which of the following would be an appropriate intervention to prevent complications associated with the respiratory system?

Maintain the client in a semi-Fowler's position. Explanation: The nurse maintains the client in the semi-Fowler's position to decrease pressure on the diaphragm by a distended abdomen and to increase respiratory expansion. Respiratory distress and hypoxia are common, and the client may develop diffuse pulmonary infiltrates, dyspnea, tachypnea, and abnormal blood gas values. The client who has undergone surgery may have multiple drains or an open surgical incision and is at risk for skin breakdown and infection. Oral food or fluid intake is not permitted; therefore, enteral or parenteral feedings may be prescribed.

A patient is being treated on the acute medical unit for acute pancreatitis. The nurse has identified a diagnosis of Ineffective Breathing Pattern Related to Pain. What intervention should the nurse perform in order to best address this diagnosis?

Maintain the patient in a semi-Fowlers position whenever possible. The nurse maintains the patient in a semi-Fowlers position to decrease pressure on the diaphragm by a distended abdomen and to increase respiratory expansion. A supine position will result in increased pressure on the diaphragm and potentially decreased respiratory expansion. Steroids and oral suctioning are not indicated.

An adult patient has been admitted to the medical unit for the treatment of acute pancreatitis. What nursing action should be included in this patients plan of care?

Measure the patients abdominal girth daily Due to the risk of ascites, the nurse should monitor the patients abdominal girth. There is no specific need to avoid the use of opioids or to monitor for dysphagia, and activity is usually limited.

The nurse identifies a potential collaborative problem of electrolyte imbalance for a client with severe acute pancreatitis. Which assessment finding alerts the nurse to an electrolyte imbalance associated with acute pancreatitis?

Muscle twitching and finger numbness Explanation: Muscle twitching and finger numbness indicate hypocalcemia, a potential complication of acute pancreatitis. Calcium may be prescribed to prevent or treat tetany, which may result from calcium losses into retroperitoneal (peripancreatic) exudate. The other data indicate other complications of acute pancreatitis but are not indicators of electrolyte imbalance.

A client diagnosed with acute pancreatitis is being transferred to another facility. The nurse caring for the client completes the transfer summary, which includes information about the client's drinking history and other assessment findings. Which assessment findings confirm the diagnosis of acute pancreatitis?

Pain with abdominal distention and hypotension Explanation: Assessment findings associated with pancreatitis include pain with abdominal distention and hypotension. Blood in stools and recent hypertension aren't associated with pancreatitis; fatty diarrhea and hypotension are usually present. Presence of easy bruising and bradycardia aren't found with pancreatitis; the client typically experiences tachycardia, not bradycardia. Adventitious breath sounds and hypertension aren't associated with pancreatitis.

One difference between cholesterol stones (left) and the stones on the right are that the ones on the right account for only 10% to 25% of cases of stones in the United States. What is the name of the stones on the right?

Pigment Explanation: There are two major types of gallstones: those composed predominantly of pigment and those composed primarily of cholesterol. Pigment stones probably form when unconjugated pigments in the bile precipitate to form stones; these stones account for 10% to 25% of cases in the United States. There are no gallstones with the names of pearl, patterned, or pixelated. Pigment stones are green; others are white/different colors

Which condition is the major cause of morbidity and mortality in clients with acute pancreatitis?

Pancreatic necrosis Explanation: Pancreatic necrosis is a major cause of morbidity and mortality in clients with acute pancreatitis. Shock and multiple organ failure may occur with acute pancreatitis. Tetany is not a major cause of morbidity and mortality in clients with acute pancreatitis.

Which of the following conditions is most likely to involve a nursing diagnosis of fluid volume deficit?

Pancreatitis Explanation: Hypotension is typical and reflects hypovolemia and shock caused by the loss of large amounts of protein-rich fluid into the tissues and peritoneal cavity. The other conditions are less likely to exhibit fluid volume deficit.

The nurse is caring for a client with acute pancreatitis who is admitted to the intensive care unit to monitor for pulmonary complications. What is the nurse's understanding of the pathophysiology of pulmonary complications related to pancreatitis?

Pancreatitis can elevate the diaphragm and alter the breathing pattern. Explanation: Aggressive pulmonary care is required for clients with acute pancreatitis. Pancreatitis can elevate the diaphragm and alter the breathing pattern of clients. Pancreatitis can cause retention of pulmonary secretions but does not thicken the secretions. Acute pancreatitis does not alter the hemoglobin.

When caring for a client with acute pancreatitis, the nurse should use which comfort measure?

Positioning the client on the side with the knees flexed Explanation: The nurse should place the client with acute pancreatitis in a side-lying position with knees flexed; this position promotes comfort by decreasing pressure on the abdominal muscles. The nurse should administer an analgesic, as needed and ordered, before pain becomes severe, rather than once each shift. Because the client needs a quiet, restful environment during the acute disease stage, the nurse should discourage frequent visits from family and friends. Frequent oral feedings are contraindicated during the acute stage to allow the pancreas to rest.

A nurse is assessing a patient who has been diagnosed with cholecystitis, and is experiencing localized abdominal pain. When assessing the characteristics of the patients pain, the nurse should anticipate that it may radiate to what region?

Right shoulder The patient may have biliary colic with excruciating upper right abdominal pain that radiates to the back or right shoulder. Pain from cholecystitis does not typically radiate to the left upper chest, inguinal area, neck, or jaw.

A client with gallstones is diagnosed with acute pancreatitis and is requesting information about the physiology of the gallbladder. Which information will the nurse include about the function of this organ?

Releases bile in response to cholecystokinin Explanation: The gallbladder is a pear-shaped, hollow, saclike organ that lies in a shallow depression on the inferior surface of the liver. When food enters the duodenum, the gallbladder contracts and the sphincter of Oddi relaxes. Relaxation of this sphincter allows the bile to enter the intestine. This response is mediated by secretion of the hormone cholecystokinin (CCK) from the intestinal wall. Gallstones can block the bile duct and digestive juices to the pancreas causing acute pancreatitis. The gallbladder functions as a storage depot for bile. Bile does not digest carbohydrates in the jejunum. The liver controls the flow of trypsin to digest proteins.

A client is admitted to the health care facility with abdominal pain, a low-grade fever, abdominal distention, and weight loss. The physician diagnoses acute pancreatitis. What is the primary goal of nursing care for this client?

Relieving abdominal pain Explanation: The predominant clinical feature of acute pancreatitis is abdominal pain, which usually reaches peak intensity several hours after onset of the illness. Therefore, relieving abdominal pain is the nurse's primary goal. Because acute pancreatitis causes nausea and vomiting, the nurse should try to prevent fluid volume deficit, not overload. The nurse can't help the client achieve adequate nutrition or understand the disease and its treatment until the client is comfortable and no longer in pain.

A client being treated for pancreatitis faces the risk of atelectasis. Which of the following interventions would be important to implement to minimize this risk?

Reposition the client every 2 hours. Explanation: Repositioning the client every 2 hours minimizes the risk of atelectasis in a client who is being treated for pancreatitis. The client should be instructed to cough every 2 hours to reduce atelectasis. Monitoring the pulse oximetry helps show changes in respiratory status and promote early intervention, but it would do little to minimize the risk of atelectasis. Withholding oral feedings limits the reflux of bile and duodenal contents into the pancreatic duct.

A patient who had surgery for gallbladder disease has just returned to the postsurgical unit from postanesthetic recovery. The nurse caring for this patient knows to immediately report what assessment finding to the physician?

Rigidity of the abdomen The location of the subcostal incision will likely cause the patient to take shallow breaths to prevent pain, which may result in decreased breath sounds. The nurse should remind patients to take deep breaths and cough to expand the lungs fully and prevent atelectasis. Acute pain is an expected assessment finding following surgery; analgesics should be administered for pain relief. Abdominal splinting or application of an abdominal binder may assist in reducing the pain. Bile may continue to drain from the drainage tract after surgery, which will require frequent changes of the abdominal dressing. Increased abdominal tenderness and rigidity should be reported immediately to the physician, as it may indicate bleeding from an inadvertent puncture or nicking of a major blood vessel during the surgical procedure

A client comes to the ED with severe abdominal pain, nausea, and vomiting. The physician plans to rule out acute pancreatitis. The nurse would expect the diagnosis to be confirmed by an elevated result on which laboratory test?

Serum amylase Explanation: Serum amylase and lipase concentrations are used to make the diagnosis of acute pancreatitis. Serum amylase and lipase concentrations are elevated within 24 hours of the onset of symptoms. Serum amylase usually returns to normal within 48 to 72 hours, but the serum lipase concentration may remain elevated for a longer period, often days longer than amylase. Urinary amylase concentrations also become elevated and remain elevated longer than serum amylase concentrations

The nursing student has just reviewed material in the course textbook regarding pancreatitis. The student knows that a major symptom of pancreatitis that causes the client to seek medical care is:

Severe abdominal pain Explanation: The pain of acute pancreatitis is often very severe, necessitating the liberal use of analgesics. Jaundice is indicative of a bile duct obstruction. Fever and mental agitation are not indicative of pancreatitis.

A 37-year-old male patient presents at the emergency department (ED) complaining of nausea and vomiting and severe abdominal pain. The patients abdomen is rigid, and there is bruising to the patients flank. The patients wife states that he was on a drinking binge for the past 2 days. The ED nurse should assist in assessing the patient for what health problem?

Severe pancreatitis with possible peritonitis Severe abdominal pain is the major symptom of pancreatitis that causes the patient to seek medical care. Pain in pancreatitis is accompanied by nausea and vomiting that does not relieve the pain or nausea. Abdominal guarding is present and a rigid or board-like abdomen may be a sign of peritonitis. Ecchymosis (bruising) to the flank or around the umbilicus may indicate severe peritonitis. Pain generally occurs 24 to 48 hours after a heavy meal or alcohol ingestion. The link with alcohol intake makes pancreatitis a more likely possibility than appendicitis or cholecystitis

A patient has undergone a laparoscopic cholecystectomy and is being prepared for discharge home. When providing health education, the nurse should prioritize which of the following topics?

Signs and symptoms of intra-abdominal complications Because of the early discharge following laparoscopic cholecystectomy, the patient needs thorough education in the signs and symptoms of complications. Fluid balance is not typically a problem in the recovery period after laparoscopic cholecystectomy. There is no need for blood glucose monitoring or pancreatic enzymes.

A nurse is assessing an elderly patient with gallstones. The nurse is aware that the patient may not exhibit typical symptoms, and that particular symptoms that may be exhibited in the elderly patient may include what?

Signs and symptoms of septic shock The elderly patient may not exhibit the typical symptoms of fever, pain, chills jaundice, and nausea and vomiting. Symptoms of biliary tract disease in the elderly may be accompanied or preceded by those of septic shock, which include oliguria, hypotension, change in mental status, tachycardia, and tachypnea.

A 55-year-old man has been newly diagnosed with acute pancreatitis and admitted to the acute medical unit. How should the nurse most likely explain the pathophysiology of this patients health problem?

The enzymes that your pancreas produces have damaged the pancreas itself. Although the mechanisms causing pancreatitis are unknown, pancreatitis is commonly described as the autodigestion of the pancreas. Less commonly, toxic substances and microorganisms are implicated as the cause of pancreatitis.

A patient with acute pancreatitis puts the call bell on to tell the nurse about an increase in pain. The nurse observes the patient guarding; the abdomen is board-like and no bowel sounds are detected. What is the major concern for this patient?

The patient has developed peritonitis. Explanation: Abdominal guarding is present. A rigid or board-like abdomen may develop and is generally an ominous sign, usually indicating peritonitis (Privette et al., 2011).

A nurse is caring for a patient who has been scheduled for endoscopic retrograde cholangiopancreatography (ERCP) the following day. When providing anticipatory guidance for this patient, the nurse should describe what aspect of this diagnostic procedure?

The use of moderate sedation Moderate sedation, not general anesthesia, is used during ERCP. D50 is not administered and the procedure does not involve the creation of an incision.

The physician has written the following orders for a new client admitted with pancreatitis: bed rest, nothing by mouth (NPO), and administration of total parenteral nutrition (TPN) . Which does the nurse attribute as the reason for NPO status?

To avoid inflammation of the pancreas Explanation: Pancreatic secretion is increased by food and fluid intake and may cause inflammation of the pancreas.

A patient is admitted to the ICU with acute pancreatitis. The patients family asks what causes acute pancreatitis. The critical care nurse knows that a majority of patients with acute pancreatitis have what?

Undiagnosed chronic pancreatitis Eighty percent of patients with acute pancreatitis have biliary tract disease or a history of long-term alcohol abuse. These patients usually have had undiagnosed chronic pancreatitis before their first episode of acute pancreatitis. Diabetes, an impaired immune function, and amylase deficiency are not specific precursors to acute pancreatitis

A client being treated for pancreatitis faces the risk of atelectasis. Which of the following interventions would be important to implement to minimize this risk?

Use incentive spirometry every hour. Explanation: The nurse instructs the client in techniques of coughing and deep breathing and in the use of incentive spirometry to improve respiratory function. The nurse assists the client to perform these activities every hour. Repositioning the client every 2 hours minimizes the risk of atelectasis. The client should be instructed to cough every 2 hours to reduce atelectasis. Monitoring pulse oximetry helps show changes in respiratory status and promotes early intervention, but it would do little to minimize the risk of atelectasis. Withholding analgesics is not an appropriate intervention due to the severe pain associated with pancreatitis.

A client with chronic pancreatitis is treated for uncontrolled pain. Which complication does the nurse recognize is most common in the client with chronic pancreatitis?

Weight loss Explanation: Weight loss is most common in the client with chronic pancreatitis due to decreased dietary intake secondary to anorexia or fear that eating will precipitate another attack. The other answer choices are not the most common complications related to chronic pancreatitis.

A preoperative client scheduled to have an open cholecystectomy says to the nurse, "The doctor said that after surgery, I will have a tube in my nose that goes into my stomach. Why do I need that?" What most common reason for a client having a nasogastric tube in place after abdominal surgery should the nurse include in a response?

decompression Explanation: Negative pressure exerted through a tube inserted in the stomach removes secretions and gaseous substances from the stomach, preventing abdominal distention, nausea, and vomiting. Instillations in a nasogastric tube after surgery are done when necessary to promote patency; this is not the most common purpose of a nasogastric tube after surgery. Gavage is contraindicated after abdominal surgery until peristalsis returns. Lavage after surgery may be done to promote hemostasis in the presence of gastric bleeding, but this is not the most common purpose of a nasogastric tube after surgery.
