MS2 - Ch 50: Mgmt. of Patients with Biliary Disorders

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 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.

A client with calculi in the gallbladder is said to have

Cholelithiasis 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.

Which is a clinical manifestation of cholelithiasis?

Clay-colored stools The client with gallstones has clay-colored stools and excruciating upper right quadrant pain that radiates to the back or right shoulder. The excretion of bile pigments by the kidneys makes urine very dark. The feces, no longer colored with bile pigments, are grayish (like putty) or clay colored. The client develops a fever and may have a palpable abdominal mass.

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 The gallbladder functions as a storage depot for bile.

When reviewing the history of a client with pancreatic cancer, the nurse would identify which of the following as a possible risk factor?

History of pancreatitis Pancreatitis is associated with the development of pancreatic cancer. Other factors that correlate with pancreatic cancer include diabetes mellitus, a high-fat diet, and chronic exposure to carcinogenic substances (i.e., petrochemicals). Although data are inconclusive, a relationship may exist between cigarette smoking and high coffee consumption (especially decaffeinated coffee) and the development of pancreatic carcinoma.

Which enzyme aids in the digestion of fats?

Lipase 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 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. 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.

Which condition is most likely to have a nursing diagnosis of fluid volume deficit?

Pancreatitis Hypovolemic shock from fluid shifts is a major factor in acute pancreatitis. Appendicitis, cholecystitis, and gastric ulcer are less likely to exhibit fluid volume deficit.

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 Anticholinergic medications reduce gastric and pancreatic secretion.

A client with carcinoma of the head of the pancreas is scheduled for surgery. Which of the following should a nurse administer to the client before surgery?

Vitamin K Clients with carcinoma of the head of the pancreas typically require vitamin K before surgery to correct a prothrombin deficiency. Potassium would be given only if the client's serum potassium levels were low. Oral bile acids are not prescribed for a client with carcinoma of the head of the pancreas; they are given to dissolve gallstones. Vitamin B has no implications in the surgery.

A nurse should monitor blood glucose levels for a patient diagnosed with hyperinsulinism. What blood glucose level does the nurse recognize as inadequate to sustain normal brain function?

30 mg/dL Hyperinsulinism is caused by overproduction of insulin by the pancreatic islets. Occasionally, tumors of nonpancreatic origin produce an insulin-like material that can cause severe hypoglycemia and may be responsible for seizures coinciding with blood glucose levels that are too low to sustain normal brain function (i.e., lower than 30 mg/dL [1.6 mmol/L])

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 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.

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 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.

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

Choledocholithotomy 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 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 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 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 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 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. Abdominal guarding is present. A rigid or board-like abdomen may develop and is generally an ominous sign, usually indicating peritonitis

The digestion of carbohydrates is aided by

amylase Amylase is secreted by the exocrine pancreas. Lipase aids in the digestion of fats. Trypsin aids in the digestion of proteins. Secretin is the major stimulus for increased bicarbonate secretion from the pancreas.

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

Pancreatitis 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.

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." 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.

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

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

Upon receiving the dinner tray for a client admitted with acute gallbladder inflammation, the nurse will question which of the following foods on the tray?

Hot roast beef sandwich with gravy 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 client should avoid fried foods such as roast beef because fatty foods may bring on an episode of cholecystitis.

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. 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.

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

Light-colored urine 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 planning care for a client with acute pancreatitis. Which client outcome does the nurse assign as the highest priority?

Maintaining normal respiratory function 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 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 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 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.

A client is treated for gastrointestinal problems related to chronic cholecystitis. What pathophysiological process related to cholecystitis does the nurse understand is the reason behind the client's GI problems?

Reduced or absent bile as a result of obstruction impacts digestion. Digestion is impacted by cholecystitis because an obstruction of the gallbladder results in reduced or absent bile. Contractile spasms and inflammation of the gallbladder leads to pain, not problems with digestion.

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

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 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 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.
