Which of the following would be the least important assessment in a patient diagnosed with ascites? a) Palpation of abdomen for a fluid shift b) Measurement of abdominal girth c) Foul-smelling breath d) Weight

Foul-smelling breath Explanation: Foul-smelling breath would not be considered an important assessment for this patient. Measurement of abdominal girth, weight, and palpation of the abdomen for a fluid shift are all important assessment parameters for the patient diagnosed with ascites.

Medication to treat symptoms of Liver functions

Kanamycin (Kantrex) would be used to treat hepatic encephalopathy to destroy intestinal microorganisms and decrease ammonia production. Lactulose would be used to reduce serum ammonia concentration in a client with hepatic encephalopathy. Cyclosporine (Sandimmune) would be used to prevent graft rejection after a transplant.

The nurse is teaching a patient who was admitted to the hospital with acute hepatic encephalopathy and ascites about an appropriate diet. The nurse determines that the teaching has been effective when the patient chooses which of the following food choices from the menu?

Pancakes with butter and honey and orange juice

Total parental nutrition (TPN) should be used cautiously in clients with pancreatitis because such clients:

Total parental nutrition (TPN) is used carefully in clients with pancreatitis because some clients cannot tolerate a high-glucose concentration even with insulin coverage. **Patients with pancreatitis should not be given high-fat foods because they are difficult to digest. Intake of coffee increases the risk for gallbladder contraction,

Which of the following would be the least important assessment in a patient diagnosed with ascites? a) Palpation of abdomen for a fluid shift b) Measurement of abdominal girth c) Weight d) Foul-smelling breath

Foul-smelling breath Foul-smelling breath would not be considered an important assessment for this patient. Measurement of abdominal girth, weight, and palpation of the abdomen for a fluid shift are all important assessment parameters for the patient diagnosed with ascites.

The nurse is assisting the physician with a procedure to remove ascitic fluid from a client with cirrhosis. What procedure does the nurse ensure the client understands will be performed?

Abdominal paracentesis

A client with cirrhosis has portal hypertension, which is causing esophageal varices. What is the goal of the interventions that the nurse will provide? a) Cure the cirrhosis. b) Treat the esophageal varices. c) Reduce fluid accumulation and venous pressure. d) Promote optimal neurologic function.

c) Reduce fluid accumulation and venous pressure.

The nurse is providing care to a patient with gross ascites who is maintaining a position of comfort in the high semi-Fowler's position. What is the nurse's priority assessment of this patient? a) Urinary output related to increased sodium retention b) Skin assessment related to increase in bile salts c) Peripheral vascular assessment related to immobility d) Respiratory assessment related to increased thoracic pressure

d) Respiratory assessment related to increased thoracic pressure

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

Enlargement of the Liver palpated signs

Tenderness of the liver indicates recent acute enlargement with consequent stretching of the liver capsule. The absence of tenderness may imply that the enlargement is of longstanding duration.

A client with acute liver failure exhibits confusion, a declining level of consciousness, and slowed respirations. The nurse finds him very difficult to arouse. The diagnostic information which best explains the client's behavior is: elevated liver enzymes and low serum protein level. subnormal serum glucose and elevated serum ammonia levels. subnormal clotting factors and platelet count. elevated blood urea nitrogen and creatinine levels and hyperglycemia.

subnormal serum glucose and elevated serum ammonia levels. In acute liver failure, serum ammonia levels increase because the liver can't adequately detoxify the ammonia produced in the GI tract. In addition, serum glucose levels decline because the liver isn't capable of releasing stored glucose. Elevated serum ammonia and subnormal serum glucose levels depress the level of a client's consciousness. Elevated liver enzymes, low serum protein level, subnormal clotting factors and platelet count, elevated blood urea nitrogen and creatine levels, and hyperglycemia aren't as directly related to the client's level of consciousness.

A patient with cirrhosis has a massive hemorrhage from esophageal varices. Balloon tamponade therapy is used temporarily to control hemorrhage and stabilize the patient. In planning care, the nurse gives the highest priority to which of the following goals? a) Relieving the patient's anxiety b) Maintaining fluid volume c) Maintaining the airway d) Controlling bleeding

Maintaining the airway Esophageal varices are almost always caused by portal hypertension, which results from obstruction of the portal circulation within the damaged liver. Maintaining the airway is the highest priority because oxygenation is essential for life. The airway is compromised by possible displacement of the tube and the inflated balloon into the oropharynx, which can cause life-threatening obstruction of the airway and asphyxiation.

A physician orders spironolactone (Aldactone), 50 mg by mouth four times daily, for a client with fluid retention caused by cirrhosis. Which finding indicates that the drug is producing a therapeutic effect? a) Blood pH of 7.25 b) Serum sodium level of 135 mEq/L c) Loss of 2.2 lb (1 kg) in 24 hours d) Serum potassium level of 3.5 mEq/L

Loss of 2.2 lb (1 kg) in 24 hours Daily weight measurement is the most accurate indicator of fluid status; a loss of 2.2 lb (1 kg) indicates loss of 1 L of fluid. Because spironolactone is a diuretic, weight loss is the best indicator of its effectiveness. This client's serum potassium and sodium levels are normal. A blood pH of 7.25 indicates acidosis, an adverse reaction to spironolactone

A client has undergone a liver biopsy. After the procedure, the nurse should place the client in which position?

On the right side Immediately after the biopsy, assist the client to turn on to the right side; place a pillow under the costal margin, and caution the client to remain in this position. In this position, the liver capsule at the site of penetration is compressed against the chest wall, and the escape of blood or bile through the perforation made for the biopsy is impeded. Positioning the client on the left side is not indicated. Positioning the client in the Trendelenburg position may be indicated if the client is in shock, but it is not the position designed for the client after liver biopsy. The high Fowler position is not indicated for the client after liver biopsy.

The nurse is providing care to a patient with gross ascites who is maintaining a position of comfort in the high semi-Fowler's position. What is the nurse's priority assessment of this patient? a) Peripheral vascular assessment related to immobility b) Respiratory assessment related to increased thoracic pressure c) Urinary output related to increased sodium retention d) Skin assessment related to increase in bile salts

Respiratory assessment related to increased thoracic pressure If a patient with ascites from liver dysfunction is hospitalized, nursing measures include assessment and documentation of intake and output (I&O;), abdominal girth, and daily weight to assess fluid status. The nurse also closely monitors the respiratory status because large volumes of ascites can compress the thoracic cavity and inhibit adequate lung expansion. The nurse monitors serum ammonia, creatinine, and electrolyte levels to assess electrolyte balance, response to therapy, and indications of encephalopathy.

When caring for a client with advanced cirrhosis and hepatic encephalopathy, which assessment finding should the nurse report immediately?

Change in the client's handwriting and/or cognitive performance The earliest symptoms of hepatic encephalopathy include mental status changes and motor disturbances. The client will appear confused and unkempt and have altered mood and sleep patterns. Neurologic status should be assessed frequently. Mental status is monitored by the nurse keeping the client's daily record of handwriting and arithmetic performance. The nurse should report any change in mental status immediately. Chronic fatigue, anorexia, dyspepsia, nausea, vomiting, and diarrhea or constipation with accompanying weight loss are regular symptoms of cirrhosis.

What test should the nurse prepare the client for that will locate stones that have collected in the common bile duct? Colonoscopy Abdominal x-ray Cholecystectomy Endoscopic retrograde cholangiopancreatography (ERCP)

ERCP

A client with liver and renal failure has severe ascites. On initial shift rounds, his primary nurse finds his indwelling urinary catheter collection bag too full to store more urine. The nurse empties more than 2,000 ml from the collection bag. One hour later, she finds the collection bag full again. The nurse notifies the physician, who suspects that a bladder rupture is allowing the drainage of peritoneal fluid. The physician orders a urinalysis to be obtained immediately. The presence of which substance is considered abnormal? Creatinine Urobilinogen Chloride Albumin

albumin

A nurse is preparing a presentation for a local community group about hepatitis. Which of the following would the nurse include? a)Infection with hepatitis G is similar to hepatitis A. b)Hepatitis C increases a person's risk for liver cancer. c)Hepatitis A is frequently spread by sexual contact. d)Hepatitis B is transmitted primarily by the oral-fecal route.

Hepatitis C increases a person's risk for liver cancer. Infection with hepatitis C increases the risk of a person developing hepatic (liver) cancer. Hepatitis A is transmitted primarily by the oral-fecal route; hepatitis B is frequently spread by sexual contact and infected blood. Hepatitis E is similar to hepatitis A whereas hepatitis G is similar to hepatitis C.

A client is actively bleeding from esophageal varices. Which of the following medications would the nurse most expect to be administered to this client?

Vasopressin (Pitressin) In an actively bleeding client, medications are administered initially because they can be obtained and administered quicker than other therapies. Vasopressin (Pitressin) may be the initial mode of therapy in urgent situations, because it produces constriction of the splanchnic arterial bed and decreases portal pressure. Propranolol (Inderal) and nadolol (Corgard), beta-blocking agents that decrease portal pressure, are the most common medications used both to prevent a first bleeding episode in clients with known varices and to prevent rebleeding. Beta-blockers should not be used in acute variceal hemorrhage, but they are effective prophylaxis against such an episode.

What test should the nurse prepare the client for that will locate stones that have collected in the common bile duct? a) Colonoscopy b) Endoscopic retrograde cholangiopancreatography (ERCP) c) Cholecystectomy d) Abdominal x-ray

Endoscopic retrograde cholangiopancreatography (ERCP) ERCP locates stones that have collected in the common bile duct. A colonoscopy will not locate gallstones but only allows visualization of the large intestine. Abdominal x-ray is not a reliable locator of gallstones. A cholecystectomy is the surgical removal of the gallbladder.

A student accepted into a nursing program must begin receiving the hepatitis B series of injections. The student asks when the next two injections should be administered. What is the best response by the instructor? a) "You must have the second one in 1 year and the third the following year." b) "You must have the second one in 1 month and the third in 6 months." c) "You must have the second one in 2 weeks and the third in 1 month." d) "You must have the second one in 6 months and the third in 1 year."

b) "You must have the second one in 1 month and the third in 6 months."

The nurse is assisting the physician with a procedure to remove ascitic fluid from a client with cirrhosis. What procedure does the nurse ensure the client understands will be performed? Thoracentesis Abdominal paracentesis Abdominal CT scan Upper endoscopy

abdominal paracentesis

Which of the following medications is used to decrease portal pressure, halting bleeding of esophageal varices? Spironolactone (Aldactone) Vasopressin (Pitressin) Nitroglycerin Cimetidine (Tagamet)

vasopressin

When caring for a client with advanced cirrhosis and hepatic encephalopathy, which assessment finding should the nurse report immediately? a) Anorexia for more than 3 days b) Weight loss of 2 pounds in 3 days c) Constipation for more than 2 days d) Change in the client's handwriting and/or cognitive performance

d) Change in the client's handwriting and/or cognitive performance

Albumin Explanation: Albumin is an abnormal finding in a routine urine specimen. Ascites present in liver failure contain albumin; therefore, if the bladder ruptured, ascites containing albumin would drain from the indwelling urinary catheter because the catheter is no longer contained in the bladder. Creatinine, urobilinogen, and chloride are normally found in urine.

Vitamin and Iron Storage

Vitamins A, B, and D and several of the B-complex vitamins are stored in large amounts in the liver. Certain substances, such as iron and copper, are also stored in the liver.

The single modality of pharmacologic therapy for chronic type B viral hepatitis is:

Alpha-interferon

Cirrhosis

Is a chronic liver disorder characterized by fibrotic changes, the formation of dense connective tissue within the liver, subsequent degenerative changes, and loss of functional liver tissue

Albumin. Albumin is an abnormal finding in a routine urine specimen. Ascites present in liver failure contain albumin; therefore, if the bladder ruptured, ascites containing albumin would drain from the indwelling urinary catheter because the catheter is no longer contained in the bladder. Creatinine, urobilinogen, and chloride are normally found in urine.

When assessing a client with cirrhosis of the liver, which of the following stool characteristics is the client likely to report?

Clay-colored or whitish

Enlarged liver size, Ascites, Hemorrhoids Early in the course of cirrhosis, the liver tends to be large, and the cells are loaded with fat. The liver is firm and has a sharp edge that is noticeable on palpation. Portal obstruction and ascites, late manifestations of cirrhosis, are caused partly by chronic failure of liver function and partly by obstruction of the portal circulation. The obstruction to blood flow through the liver caused by fibrotic changes also results in the formation of collateral blood vessels in the GI system and shunting of blood from the portal vessels into blood vessels with lower pressures. These distended blood vessels form varices or hemorrhoids, depending on their location. Because of inadequate formation, use, and storage of certain vitamins (notably vitamins A, C, and K), signs of deficiency are common, particularly hemorrhagic phenomena associated with vitamin K deficiency. Additional clinical manifestations include deterioration of mental and cognitive function with impending hepatic encephalopathy and hepatic coma, as previously described.

The nurse is caring for a client with cirrhosis. Which assessment findings indicate that the client has deficient vitamin K absorption caused by this hepatic disease?

Purpura and petechiae. A hepatic disorder, such as cirrhosis, may disrupt the liver's normal use of vitamin K to produce prothrombin (a clotting factor). Consequently, the nurse should monitor the client for signs of bleeding, including purpura and petechiae. Dyspnea and fatigue suggest anemia. Ascites and orthopnea are unrelated to vitamin K absorption. Gynecomastia and testicular atrophy result from decreased estrogen metabolism by the diseased liver.

The nurse is caring for a client with cirrhosis. Which assessment findings indicate that the client has deficient vitamin K absorption caused by this hepatic disease? a) Purpura and petechiae b) Dyspnea and fatigue c) Gynecomastia and testicular atrophy d) Ascites and orthopnea

a) Purpura and petechiae

What test should the nurse prepare the client for that will locate stones that have collected in the common bile duct?

Endoscopic retrograde cholangiopancreatography (ERCP)

A client with hepatic cirrhosis questions the nurse about the possible use of an herbal supplement—milk thistle—to help heal the liver. Which is the most appropriate response by the nurse?

"Silymarin from milk thistle has anti-inflammatory and antioxidant properties that may have beneficial effects, especially in hepatitis. However, you should always notify your primary care provider of any herbal remedies being used so drug interactions can be evaluated."

"You must have the second one in 1 month and the third in 6 months."

A client has ascites. Which of the following interventions would the nurse prepare to assist with implementing to help the client control this condition? Select all that apply.

- Instructing the client to remove salty and salted foods from the diet - Administering prescribed spironolactone (Aldactone) - Assisting with placement of a transjugular intrahepatic portosystemic shunt

A client with cirrhosis is at risk for developing esophageal varices. Which of the following instructions should a nurse provide the client to minimize such risk? a) Increase intake of potassium-rich food. b) Avoid intake of sodium-rich food. c) Abstain from drinking alcohol. d) Use aspirin at least once a day.

Abstain from drinking alcohol. Explanation: A soft diet and elimination of alcohol, aspirin, and other locally irritating substances minimize the risk for developing esophageal varices. Intake of sodium- or potassium-rich food has no effect on the formation of varices.

An 87-year-old client is in the ICU where you practice nursing. He was admitted for critical care due to his esophageal varices and his precarious physical condition. Which of the following could result in causing his varices to hemorrhage? a) All options are correct b) Little protective tissue to protect fragile veins c) Chemical irritation d) Rough food

All options are correct Explanation: Esophageal varices overfill as a result of portal hypertension. They are especially vulnerable to bleeding because they lie superficially in the mucosa, contain little protective elastic tissue, and are easily traumatized by rough food or chemical irritation.

When inspecting the abdomen of a client with cirrhosis, the nurse observes that the veins over the abdomen are dilated. The nurse documents this finding as which of the following?

Caput medusae

A client is admitted for suspected GI disease. Assessment data severe abdominal pain that presents several hours after large meal. The nurse suspects the client has:

Hemolytic

Which type of jaundice seen in adults is the result of increased destruction of red blood cells? a)Hemolytic b)Nonobstructive c)Hepatocellular d)Obstructive

Hemolytic Hemolytic jaundice results because, although the liver is functioning normally, it cannot excrete the bilirubin as quickly as it is formed. Obstructive jaundice is the result of liver disease. Nonobstructive jaundice occurs with hepatitis. Hepatocellular jaundice is the result of liver disease.

Which type of jaundice seen in adults is the result of increased destruction of red blood cells? a) Hepatocellular b) Nonobstructive c) Obstructive d) Hemolytic

Hemolytic Explanation: Hemolytic jaundice results because, although the liver is functioning normally, it cannot excrete the bilirubin as quickly as it is formed. Obstructive jaundice is the result of liver disease. Nonobstructive jaundice occurs with hepatitis. Hepatocellular jaundice is the result of liver disease.

A patient has an elevated serum ammonia level and is exhibiting mental status changes. The nurse should suspect which of the following conditions?

Hepatic encephalopathy

Which of the following symptoms would indicate that a client with chronic pancreatitis has developed secondary diabetes?

Increased appetite and thirst

Clients with cirrhosis should watch intake this supplement to their diet, for its increase the risk of hepatic encephalopthy.

Intake of high protein

While conducting a physical examination of a client, which of the following skin findings would alert the nurse to the possibility of liver problems? Select all that apply.

Jaundice Petechiae Ecchymoses

Liver malfunction*

Jaundice occurs when the bilirubin concentration in the blood is abnormally elevated.

A client with cirrhosis has a massive hemorrhage from esophageal varices. Balloon tamponade is used temporarily to control hemorrhage and stabilize the client. In planning care, the nurse gives the highest priority to which goal?

Maintaining the airway

When performing a physical examination on a client with cirrhosis, a nurse notices that the client's abdomen is enlarged. Which of the following interventions should the nurse consider? a) Ask the client about food intake. b) Report the condition to the physician immediately. c) Provide the client with nonprescription laxatives. d) Measure abdominal girth according to a set routine.

Measure abdominal girth according to a set routine. Explanation: If the abdomen appears enlarged, the nurse measures it according to a set routine. The nurse reports any change in mental status or signs of gastrointestinal bleeding immediately. It is not essential for the client to take laxatives unless prescribed. The client's food intake does not affect the size of the abdomen in case of cirrhosis.

Which assessments are important in a client diagnosed with ascites?

Measurement of abdominal girth. Weight, and palpation of the abdomen for a fluid shift are also all important assessment parameters for the client diagnosed with ascites. Foul-smelling breath would not be considered an important assessment for this client.

To reduce risk of injury for a patient with liver disease, what initial measure can the nurse implement?

Pad the side rails on the bed

A nurse is gathering equipment and preparing to assist with a sterile bedside procedure to withdraw fluid from a patient's abdomen. The procedure tray contains the following equipment: trocar, syringe, needles, and drainage tube. The patient is placed in a high Fowler's position and a BP cuff is secured around the arm in preparation for which of the following procedures? a)Abdominal ultrasound b)Paracentesis c)Liver biopsy d)Dialysis

Paracentesis Paracentesis is the removal of fluid (ascites) from the peritoneal cavity through a puncture or a small surgical incision through the abdominal wall under sterile conditions. Paracentesis may be used to withdraw ascitic fluid if the fluid accumulation is causing cardiorespiratory compromise.

A client is admitted for suspected GI disease. Assessment data reveal dull, gnawing epigastric pain that's relieved by eating. The nurse suspects the client has:

Peptic ulcer disease.

Which is the most common cause of esophageal varices?

Portal hypertension

To treat Ascites what medication is administer.

Potassium-sparing diuretics such as spironolactone are used to treat ascites.

The nurse is caring for a client with cirrhosis. Which assessment findings indicate that the client has deficient vitamin K absorption caused by this hepatic disease?

Purpura and petechiae

Which liver function study is used to show the size of the liver and hepatic blood flow and obstruction?

Radioisotope liver scan

The nurse is providing care to a patient with gross ascites who is maintaining a position of comfort in the high semi-Fowler's position. What is the nurse's priority assessment of this patient?

Respiratory assessment related to increased thoracic pressure

In what location would the nurse palpate for the liver?

Scurvy

Which of the following medications would the nurse expect the physician to order for a client with cirrhosis who develops portal hypertension? a) Kanamycin (Kantrex) b) Cyclosporine (Sandimmune) c) Spironolactone (Aldactone) d) Lactulose (Cephulac)

Spironolactone (Aldactone) Explanation: For portal hypertension, a diuretic usually an aldosterone antagonist such as spironolactone (Aldactone) is ordered. Kanamycin (Kantrex) would be used to treat hepatic encephalopathy to destroy intestinal microorganisms and decrease ammonia production. Lactulose would be used to reduce serum ammonia concentration in a client with hepatic encephalopathy. Cyclosporine (Sandimmune) would be used to prevent graft rejection after a transplant.

Why should total parental nutrition (TPN) be used cautiously in clients with pancreatitis?

Such clients cannot tolerate high-glucose concentration.

Drug Metabolism- First Pass Effect

The bioavailability of an oral medication (absorbed from the GI tract) can be decreased if the medication is metabolized to a great extent by the liver before it reaches the systemic circulation; this is known as first-pass effect. Some medications have such a large first-pass effect that their use is essentially limited to the parenteral route, or oral doses must be substantially larger than parenteral doses to achieve the same effect.

Liver Palpated with Viral Hepatitis & Alcoholic

The liver of a patient with viral hepatitis is tender, whereas that of a patient with alcoholic hepatitis is not. Enlargement of the liver is an abnormal finding that requires evaluation

Which of the following liver function studies is used to show the size of abdominal organs and the presence of masses?

Ultrasonography

Which position should be used for a client undergoing a paracentesis?

Upright at the edge of the bed

Which position should be used for a client undergoing a paracentesis?

Upright at the edge of the bed The client should be placed in an upright position on the edge of the bed or in a chair with the feet supported on a stool. The Fowler position should be used for the client confined to bed.

Which of the following is the most effective strategy to prevent hepatitis B infection?

Vaccine

Which of the following is the most effective strategy to prevent hepatitis B infection

Vaccine. The most effective strategy to prevent hepatitis B infection is through vaccination. Recommendations to prevent transmission of hepatitis B include vaccination of sexual contacts of individuals with chronic hepatitis, use of barrier protection during sexual intercourse, avoidance of sharing toothbrushes, razors with others, and covering open sores or skin lesions.

Which medication is used to decrease portal pressure, halting bleeding of esophageal varices?

Vasopressin may be the initial therapy for esophageal varices because it constricts the splanchnic arterial bed and decreases portal hypertension. Nitroglycerin has been used to prevent the side effects of vasopressin.

Which condition indicates an overdose of lactulose?

Watery diarrhea

Which of the following indicates an overdose of lactulose? a) Constipation b) Watery diarrhea c) Hypoactive bowel sounds d) Fecal impaction

What is the best response by the instructor? a) "You must have the second one in 1 year and the third the following year." b) "You must have the second one in 2 weeks and the third in 1 month." c) "You must have the second one in 1 month and the third in 6 months." d) "You must have the second one in 6 months and the third in 1 year."

"You must have the second one in 1 month and the third in 6 months." Both forms of the hepatitis B vaccine are administered intramuscularly in three doses; the second and third doses are given 1 and 6 months, respectively, after the first dose.

A client is suspected of having cirrhosis of the liver. What diagnostic procedure will the nurse prepare the client for in order to obtain a confirmed diagnosis?

A liver biopsy

A client is suspected of having cirrhosis of the liver. What diagnostic procedure will the nurse prepare the client for in order to obtain a confirmed diagnosis? a) A CT scan b) Platelet count c) A liver biopsy d) A prothrombin time

A liver biopsy A liver biopsy, which reveals hepatic fibrosis, is the most conclusive diagnostic procedure. It can be performed in the radiology department with ultrasound or CT to identify appropriate placement of the trocar or biopsy needle. A prothrombin time and platelet count will assist with determining if the client is at increased risk for bleeding.

The nurse is educating a patient with cirrhosis about the importance of maintaining a low-sodium diet. What food item would be permitted on a low-sodium diet?

A pear

The nurse is educating a patient with cirrhosis about the importance of maintaining a low-sodium diet. What food item would be permitted on a low-sodium diet?

A pear. The goal of treatment for the patient with ascites, a complication of cirrhosis, is a negative sodium balance to reduce fluid retention. Table salt, salty foods, salted butter and margarine, and all canned and frozen foods that are not specifically prepared for low-sodium (2-g sodium) diets should be avoided (Dudek, 2010). Peanut butter, a hot dog, and ham are all high in sodium. A pear is not.

Liver function test ALT - if increase means?

ALT levels increase primarily in liver disorders and may be used to monitor the course of hepatitis or cirrhosis or the effects of treatments that may be toxic to the liver.

Liver function test AST - present in tissues means?

AST is present in tissues that have high metabolic activity; therefore, the level may be increased if there is damage to or death of tissues of organs such as the heart, liver, skeletal muscle, and kidney. Although not specific to liver disease, levels of AST may be increased in cirrhosis, hepatitis, and liver cancer

A client with cirrhosis is at risk for developing esophageal varices. Which of the following instructions should a nurse provide the client to minimize such risk?

Abstain from drinking alcohol.

A patient complaining of shortness of breath is admitted with the diagnosis of cirrhosis. A nursing assessment reveals an enlarged abdomen with striae, an umbilical hernia, and 4+ pitting edema of the feet and legs. What is the most important data for the nurse to monitor? a)Bilirubin b)Temperature c)Albumin d)Hemoglobin

Albumin With the movement of albumin from the serum to the peritoneal cavity, the osmotic pressure of the serum decreases. This, combined with increased portal pressure, results in movement of fluid into the peritoneal cavity. The low oncotic pressure caused by hypoalbuminemia is a major pathophysiologic factor in the development of ascites and edema.

Which of the following terms is used to describe a chronic liver disease in which scar tissue surrounds the portal areas?

Alcoholic cirrhosis

Lactulose (Cephulac) is administered to a patient diagnosed with hepatic encephalopathy to reduce which of the following?

Ammonia. Lactulose (Cephulac) is administered to reduce serum ammonia levels. Cephulac does not influence calcium, bicarbonate, or alcohol levels.

A client is admitted for suspected GI disease. Assessment data reveal periumbilical pain that moves to the right lower quadrant and rebound tenderness. The nurse suspects the client has:

Appendicitis

When caring for a client with cirrhosis, which symptom(s) should the nurse report immediately?

Change in mental status

When caring for a client with advanced cirrhosis and hepatic encephalopathy, which assessment finding should the nurse report immediately?

Change in the client's handwriting and/or cognitive performance

A client is admitted for suspected GI disease. Assessment data reveal muscle wasting, a decrease in chest and axillary hair, and increased bleeding tendency. The nurse suspects the client has: a)peptic ulcer disease. b)cirrhosis. c)cholelithiasis. d)appendicitis.

Cirrhosis Muscle wasting, a decrease in chest and axillary hair, and increased bleeding tendencies are all symptoms of cirrhosis. The client may also have mild fever, edema, abdominal pain, and an enlarged liver. Clients with peptic ulcer disease complain of a dull, gnawing epigastric pain that's relieved by eating. Appendicitis is characterized by a periumbilical pain that moves to the right lower quadrant and rebound tenderness. Cholelithiasis is characterized by severe abdominal pain that presents several hours after a large meal.

Which is an age-related change of the hepatobiliary system?

Decreased blood flow

Which of the following the are early manifestations of liver cancer? Select all that apply.

Early manifestations of liver cancer include pain and continuous dull aching in the right upper quadrant epigastrium or back. Weight loss, anorexia, and anemia may occur. Jaundice is present only if the larger bile ducts are occluded by the pressure of malignant nodules in the hilum of the liver. Fever and vomiting are not associated manifestations.

A nursing student is reviewing for an upcoming anatomy and physiology examination. Which of the following would the student correctly identify as a function of the liver? Select all that apply. Glucose metabolism Ammonia conversion Protein metabolism Carbohydrate metabolism Zinc storage

Glucose metabolism Ammonia conversion Protein metabolism

A client has an elevated serum ammonia concentration and is exhibiting changes in mental status. The nurse should suspect which condition?

Hepatic encephalopathy. Hepatic encephalopathy is a central nervous system dysfunction resulting from liver disease. It is frequently associated with an elevated ammonia concentration that produces changes in mental status, altered level of consciousness, and coma. Portal hypertension is an elevated pressure in the portal circulation resulting from obstruction of venous flow into and through the liver. Asterixis is an involuntary flapping movement of the hands associated with metabolic liver dysfunction.

The nurse is administering medications to a patient that has elevated ammonia due to cirrhosis of the liver. What medication will the nurse give to detoxify ammonium and to act as an osmotic agent?

Lactulose (Cephulac)

The nurse is administering medications to a client that has elevated ammonia due to cirrhosis of the liver. What medication will the nurse give to detoxify ammonium and to act as an osmotic agent?

Lactulose. Lactulose is administered to detoxify ammonium and to act as an osmotic agent, drawing water into the bowel, which causes diarrhea in some clients Cholestyramine is a bile acid sequestrant and reduces pruritus. Kanamycin decreases intestinal bacteria and decreases ammonia but does not act as an osmotic agent.

Maintaining the airway Esophageal varices are almost always caused by portal hypertension, which results from obstruction of the portal circulation within the damaged liver. Maintaining the airway is the highest priority because oxygenation is essential for life. The airway can be compromised by possible displacement of the tube and the inflated balloon into the oropharynx, which can cause life-threatening obstruction of the airway and asphyxiation.

When performing a physical examination on a client with cirrhosis, a nurse notices that the client's abdomen is enlarged. Which of the following interventions should the nurse consider?

Measure abdominal girth according to a set routine.

When performing a physical examination on a client with cirrhosis, a nurse notices that the client's abdomen is enlarged. Which of the following interventions should the nurse consider?

Measure abdominal girth according to a set routine. If the abdomen appears enlarged, the nurse measures it according to a set routine. The nurse reports any change in mental status or signs of gastrointestinal bleeding immediately. It is not essential for the client to take laxatives unless prescribed. The client's food intake does not affect the size of the abdomen in case of cirrhosis.

Which assessments are important in a client diagnosed with ascites?

Measurement of abdominal girth

Age effects

Metabolism of medications by the liver decreases in the older adult, but such changes are usually accompanied by changes in intestinal absorption, renal excretion, and altered body distribution of some medications secondary to changes in fat deposition. These alterations necessitate careful medication administration and monitoring; if appropriate, reduced dosages may be needed to prevent medication toxicity

A client is scheduled to have a laparoscopic cholecystectomy as an outpatient. The client asks the nurse when he will be able to resume normal activities. What information should the nurse provide? a)Normal activities may be resumed in 1 month. b)Normal activities may be resumed in 2 weeks. c)Normal activities may be resumed in 1 week. d)Normal activities may be resumed the day after surgery.

Normal activities may be resumed in 1 week. A prolonged recovery period usually is unnecessary. Most clients resume normal activities within 1 week.

A client has a blockage of the passage of bile from a stone in the common bile duct. What type of jaundice does the nurse suspect this client has?

Obstructive jaundice

A patient has undergone a liver biopsy. Which of the following postprocedure positions is appropriate? a) On the right side b) Trendelenburg c) High Fowler's d) On the left side

On the right side Explanation: In this position, the liver capsule at the site of penetration is compressed against the chest wall, and the escape of blood or bile through the perforation made for the biopsy is impeded. Positioning the patient on his left side is not indicated. Positioning the patient in the Trendelenburg position may be indicated if the patient is in shock, but is not the position designed for the patient after liver biopsy. High Fowler's position is not indicated for the patient after liver biopsy.

What initial measure can the nurse implement to reduce risk of injury for a client with liver disease?

Pad the side rails on the bed

The most common cause of esophageal varices includes which of the following? a)Portal hypertension b)Jaundice c)Asterixis d)Ascites

Portal hypertension Esophageal varices are almost always caused by portal hypertension, which results from obstruction of the portal circulation within the damaged liver. Jaundice occurs when the bilirubin concentration in the blood is abnormally elevated. Ascites results from circulatory changes within the diseased liver. Asterixis is an involuntary flapping movement of the hands associated with metabolic liver dysfunction.

The nurse is caring for a client with cirrhosis. Which assessment findings indicate that the client has deficient vitamin K absorption caused by this hepatic disease? a) Gynecomastia and testicular atrophy b) Dyspnea and fatigue c) Ascites and orthopnea d) Purpura and petechiae

Purpura and petechiae A hepatic disorder, such as cirrhosis, may disrupt the liver's normal use of vitamin K to produce prothrombin (a clotting factor). Consequently, the nurse should monitor the client for signs of bleeding, including purpura and petechiae. Dyspnea and fatigue suggest anemia. Ascites and orthopnea are unrelated to vitamin K absorption. Gynecomastia and testicular atrophy result from decreased estrogen metabolism by the diseased liver.

The nurse is providing care to a patient with gross ascites who is maintaining a position of comfort in the high semi-Fowler's position. What is the nurse's priority assessment of this patient?

Silymarin from milk thistle has anti-inflammatory and antioxidant properties that may have beneficial effects, especially in hepatitis.However, you should always notify your primary care provider of any herbal remedies being used so drug interactions can be evaluated.

Spider angiomas (seen on the skin) in liver dysfunction

Spider angioma. This vascular (arterial) spider appears on the skin. Beneath the elevated center and radiating branches, the blood vessels are looped and tortuous.

The nurse is concerned about potassium loss when a diuretic is prescribed for a patient with ascites and edema. What diuretic may be ordered that spares potassium and prevents hypokalemia?

Spironolactone (Aldactone)

Technique for palpating the liver.

Technique for palpating the liver. The examiner places one hand under the right lower rib cage and presses downward during inspiration with light pressure with the other hand.

The client's hepatic function is decreasing

The client's hepatic function is decreasing The decreased level of consciousness caused by an increased serum ammonia level indicates hepatic disfunction.

A nurse is caring for a client with cirrhosis. The nurse assesses the client at noon and discovers that the client is difficult to arouse and has an elevated serum ammonia level. The nurse should suspect which situation? The client's hepatic function is decreasing. The client didn't take his morning dose of lactulose (Cephulac). The client is relaxed and not in pain. The client is avoiding the nurse.

The client's hepatic function is decreasing.

Ammonia, the major etiologic factor in the development of encephalopathy, inhibits neurotransmission. Increased levels of ammonia are damaging to the body. The largest source of ammonia is from:

The digestion of dietary and blood proteins. Circumstances that increase serum ammonia levels tend to aggravate or precipitate hepatic encephalopathy. The largest source of ammonia is the enzymatic and bacterial digestion of dietary and blood proteins in the GI tract. Ammonia from these sources increases as a result of GI bleeding (ie, bleeding esophageal varices, chronic GI bleeding), a high-protein diet, bacterial infection, or uremia.

Palpated Liver of Cirrhosis signs

The liver of a patient with cirrhosis is small and hard in late-stage cirrhosis.

Which symptoms will a nurse observe most commonly in clients with pancreatitis?

The most common symptom in clients with pancreatitis is severe radiating abdominal pain midabdominal to upper abdominal pain, radiating to both sides and straight to the back.

A patient is scheduled for a diagnostic paracentesis, but when coagulation studies were reviewed, the nurse observed they were abnormal. How does the nurse anticipate the physician will proceed with the paracentesis? The physician will use an ultrasound guided paracentesis The physician will not perform the procedure The physician will proceed with the paracentesis at the bedside The physician will have the nurse administer packed RBCs prior to the paracentesis.

The physician will use an ultrasound guided paracentesis

Alcohol, which is toxic to the liver, is a common cause of hepatic disorders. As part of health teaching, the nurse advises a group of women that the amount of daily alcohol use should be limited to the equivalent of: -Two 12 oz bottles of beer. -One 6 oz martini. -Two 6 oz glasses of wine. -One 2 oz glass of a mixed drink (gin and tonic).

Two 6 oz glasses of wine. Intake of 60 g/day for men and 30 g/d for women (10 g of alcohol is equivalent to 1 oz of bourbon, 12 ounces of beer, or 4 ounces of red wine) is sufficient to cause liver injury.

Which of the following liver function studies is used to show the size of abdominal organs and the presence of masses? a) Angiography b) Ultrasonography c) Electroencephalogram d) Magnetic resonance imaging

Ultrasonography Explanation: A ultrasonography will show the size of the abdominal organs and the presence of masses. Magnetic resonance imaging is used to detect hepatic neoplasms. An angiography is used to visualize hepatic circulation and detect the presence and nature of hepatic masses. An electroencephalogram is used to detect abnormalities that occur with hepatic coma.

Which of the following is the most effective strategy to prevent hepatitis B infection? a)Vaccine b)Barrier protection during intercourse c)Avoid sharing toothbrushes d)Covering open sores

Vaccine The most effective strategy to prevent hepatitis B infection is through vaccination. Recommendations to prevent transmission of hepatitis B include vaccination of sexual contacts of individuals with chronic hepatitis, use of barrier protection during sexual intercourse, avoidance of sharing toothbrushes, razors with others, and covering open sores or skin lesions.

Which medication is used to decrease portal pressure, halting bleeding of esophageal varices?

Vasopressin

A client with severe and chronic liver disease is showing manifestations related to inadequate vitamin intake and metabolism. He reports difficulty driving at night because he cannot see well. Which of the following vitamins is most likely deficient for this client? a) Vitamin A b) Thiamine c) Riboflavin d) Vitamin K

Vitamin A Problems common to clients with severe chronic liver dysfunction result from inadequate intake of sufficient vitamins. Vitamin A deficiency results in night blindness and eye and skin changes. Thiamine deficiency can lead to beriberi, polyneuritis, and Wernicke-Korsakoff psychosis. Riboflavin deficiency results in characteristic skin and mucous membrane lesions. Vitamin K deficiency can cause hypoprothrombinemia, characterized by spontaneous bleeding and ecchymoses.

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

What test should the nurse prepare the client for that will locate stones that have collected in the common bile duct? a) Abdominal x-ray b) Cholecystectomy c) Endoscopic retrograde cholangiopancreatography (ERCP) d) Colonoscopy

c) Endoscopic retrograde cholangiopancreatography (ERCP)

Which assessments are important in a client diagnosed with ascites? a) Palpation of abdomen for a fluid shift b) Foul smelling breath c) Measurement of abdominal girth d) Weight

c) Measurement of abdominal girth

A client was admitted for critical care due to esophageal varices and precarious physical condition. What could cause the client's varices to hemorrhage? a) rough food b) chemical irritation c) little protective tissue to protect fragile veins d) All options are correct

d) All options are correct

Hepatotoxins

e.g., industrial chemicals, other toxins, alcohol, iv drug use, medications, dietary supplements, over counter meds, herbal remedies

A physician orders lactulose (Cephulac), 30 ml three times daily, when a client with cirrhosis develops an increased serum ammonia level. To evaluate the effectiveness of lactulose, the nurse should monitor: urine output. abdominal girth. stool frequency. level of consciousness (LOC).

loc

What is the recommended dietary treatment for a client with chronic cholecystitis? low-fat diet high-fiber diet low-residue diet low-protein diet

low fat

What is the recommended dietary treatment for a client with chronic cholecystitis?

low-fat diet The bile secreted from the gallbladder helps the body absorb and break down dietary fats. If the gallbladder is not functioning properly, then it will not secrete enough bile to help digest the dietary fat. This can lead to further complications; therefore, a diet low in fat can be used to prevent complications.

subnormal serum glucose and elevated serum ammonia levels.

Which of the following diagnostic studies definitely confirms the presence of ascites? Ultrasound of liver and abdomen Abdominal x-ray Colonoscopy Computed tomography of abdomen

ultrasound

Which type of positioning should be utilized for a patient undergoing a paracentesis? Upright at the edge of the bed Prone Trendelenburg Supine

upright on the edge of the bed

Which of the following is the most effective strategy to prevent hepatitis B infection? Vaccine Barrier protection during intercourse Covering open sores Avoid sharing toothbrushes

vaccine

A nurse is taking health history data from a client. Use of which of the following medications would especially alert the nurse to an increased risk of hepatic dysfunction and disease in this client? Select all that apply. • Diazepam • Valproic acid • Insulin • Acetaminophen • Ketoconazole

• Acetaminophen • Ketoconazole • Valproic acid

The nurse completing a plan of care for a client with cirrhosis who has ascites and 4+ pitting edema of the feet and legs identifies a nursing diagnosis of risk for impaired skin integrity. Which nursing intervention is appropriate for this problem?

Arrange for a low air loss bed. Initiating the use of an alternating-pressure mattress or low air loss bed decreases the risk for skin breakdown due to prolonged pressure on bony prominences.

When assessing a client with cirrhosis of the liver, which of the following stool characteristics is the client likely to report?

Clay-colored or whitish Many clients report passing clay-colored or whitish stools as a result of no bile in the gastrointestinal tract. The other stool colors would not be absolute indicators of cirrhosis of the liver but may indicate other GI tract disorders.

A physician orders spironolactone (Aldactone), 50 mg by mouth four times daily, for a client with fluid retention caused by cirrhosis. Which finding indicates that the drug is producing a therapeutic effect? Serum potassium level of 3.5 mEq/L Loss of 2.2 lb (1 kg) in 24 hours Serum sodium level of 135 mEq/L Blood pH of 7.25

Daily weight measurement is the most accurate indicator of fluid status; a loss of 2.2 lb (1 kg) indicates loss of 1 L of fluid. Because spironolactone is a diuretic, weight loss is the best indicator of its effectiveness. This client's serum potassium and sodium levels are normal. A blood pH of 7.25 indicates acidosis, an adverse reaction to spironolactone.

Which of the following is an age-related change of the hepatobiliary system?

Decreased blood flow

What test should the nurse prepare the client for that will locate stones that have collected in the common bile duct?

Endoscopic retrograde cholangiopancreatography (ERCP) -------ERCP locates stones that have collected in the common bile duct. A colonoscopy will not locate gallstones but only allows visualization of the large intestine. Abdominal x-ray is not a reliable locator of gallstones. A cholecystectomy is the surgical removal of the gallbladder.

The client's husband says that he has noticed the client has been moody and slightly confused. Which of the following problems is most consistent with the client's clinical manifestations?

Hepatic encephalopathy ———-The earliest symptoms of hepatic encephalopathy include minor mental changes and motor disturbances. The client appears slightly confused and unkempt and has alterations in mood and sleep patterns. The client tends to sleep during the day and have restlessness and insomnia at night. As hepatic encephalopathy progresses, the client may become difficult to awaken and completely disoriented with respect to time and place. With further progression, the client lapses into frank coma and may have seizures. Simple tasks, such as handwriting, become difficult.

A nurse is preparing a presentation for a local community group about hepatitis. Which of the following would the nurse include?

Hepatitis C increases a person's risk for liver cancer.

A client has developed drug-induced hepatitis from a drug reaction to antidepressants. What treatment does the nurse anticipate the client will receive to treat the reaction?

High-dose corticosteroids

Clients diagnosed with esophageal varices are at risk for hemorrhagic shock. Which is a sign of potential hypovolemia?

Hypotension

A client is being prepared to undergo laboratory and diagnostic testing to confirm the diagnosis of cirrhosis. Which test would the nurse expect to be used to provide definitive confirmation of the disorder?

Liver biopsy

Palpitated Liver of Acute Hepatitis

Liver of a patient with acute hepatitis is soft and the hand easily moves the edges.

Loss of 2.2 lb (1 kg) in 24 hours. Daily weight measurement is the most accurate indicator of fluid status; a loss of 2.2 lb (1 kg) indicates loss of 1 L of fluid. Because spironolactone is a diuretic, weight loss is the best indicator of its effectiveness. This client's serum potassium and sodium levels are normal. A blood pH of 7.25 indicates acidosis, an adverse reaction to spironolactone.

A patient who had a recent myocardial infarction was brought to the emergency department with bleeding esophageal varices and is presently receiving fluid resuscitation. What first-line pharmacologic therapy does the nurse anticipate administering to control the bleeding from the varices?

Octreotide (Sandostatin)

The nurse is caring for a client with cirrhosis. Which assessment findings indicate that the client has deficient vitamin K absorption caused by this hepatic disease? a) Dyspnea and fatigue b) Gynecomastia and testicular atrophy c) Purpura and petechiae d) Ascites and orthopnea

Purpura and petechiae Explanation: A hepatic disorder, such as cirrhosis, may disrupt the liver's normal use of vitamin K to produce prothrombin (a clotting factor). Consequently, the nurse should monitor the client for signs of bleeding, including purpura and petechiae. Dyspnea and fatigue suggest anemia. Ascites and orthopnea are unrelated to vitamin K absorption. Gynecomastia and testicular atrophy result from decreased estrogen metabolism by the diseased liver.

A client with cirrhosis has portal hypertension, which is causing esophageal varices. What is the goal of the interventions that the nurse will provide?

Reduce fluid accumulation and venous pressure.

Subnormal serum glucose and elevated serum ammonia levels. In acute liver failure, serum ammonia levels increase because the liver can't adequately detoxify the ammonia produced in the GI tract. In addition, serum glucose levels decline because the liver isn't capable of releasing stored glucose. Elevated serum ammonia and subnormal serum glucose levels depress the level of a client's consciousness.

The client's hepatic function is decreasing.

Which of the following is the most effective strategy to prevent hepatitis B infection? a) Vaccine b) Barrier protection during intercourse c) Avoid sharing toothbrushes d) Covering open sores

Vaccine Explanation: The most effective strategy to prevent hepatitis B infection is through vaccination. Recommendations to prevent transmission of hepatitis B include vaccination of sexual contacts of individuals with chronic hepatitis, use of barrier protection during sexual intercourse, avoidance of sharing toothbrushes, razors with others, and covering open sores or skin lesions.

Which of the following medications is used to decrease portal pressure, halting bleeding of esophageal varices? a)Spironolactone (Aldactone) b)Nitroglycerin c)Vasopressin (Pitressin) d)Cimetidine (Tagamet)

Vasopressin (Pitressin) Vasopressin may be the initial therapy for esophageal varices, because it constricts the splanchnic arterial bed and decreases portal hypertension. Nitroglycerin has been used to prevent the side effects of vasopressin. Aldactone and Tagamet do not decrease portal hypertension.

Vitamin A

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? a) Vitamin K b) Oral bile acids c) Potassium d) Vitamin B

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.

The nurse is administering Cephulac (lactulose) to decrease the ammonia level in a patient who has hepatic encephalopathy. What should the nurse carefully monitor for that may indicate a medication overdose?

Watery diarrhea

Which of the following indicates an overdose of lactulose? a) Watery diarrhea b) Fecal impaction c) Constipation d) Hypoactive bowel sounds

Watery diarrhea The patient receiving lactulose is monitored closely for the development of watery diarrheal stool, which indicates a medication overdose.

The nurse is caring for a patient who has ascites as a result of hepatic dysfunction. What intervention can the nurse provide to determine if the ascites is increasing? Select all that apply. a) Perform daily weights. b) Measure abdominal girth daily. c) Monitor number of bowel movements per day. d) Assess and document vital signs every 4 hours. e) Measure urine output every 8 hours.

a) Perform daily weights. b) Measure abdominal girth daily.

Many Medications are responsible for disease to liver

acetaminophen [Tylenol], ketoconazole [Nizoral], and valproic acid [Depakene]) are responsible for hepatic dysfunction and disease

A client has just been diagnosed with hepatitis A. On assessment, the nurse expects to note: a) anorexia, nausea, and vomiting. b) eructation and constipation. c) abdominal ascites. d) severe abdominal pain radiating to the shoulder.

anorexia, nausea, and vomiting. Early hallmark signs and symptoms of hepatitis A include anorexia, nausea, vomiting, fatigue, and weakness. Abdominal pain may occur but doesn't radiate to the shoulder. Eructation and constipation are common in gallbladder disease, not hepatitis A. Abdominal ascites is a sign of advanced hepatic disease, not an early sign of hepatitis A.

A client with hepatitis C develops liver failure and GI hemorrhage. The blood products that most likely bring about hemostasis in the client are:

cryoprecipitate and fresh frozen plasma.

A nurse educator is providing an in-service to a group of nurses working on a medical floor that specializes in liver disorders. What is an important education topic regarding ingestion of medications? a) medications becoming ineffective in clients with liver disease b) need for increased drug dosages c) need for more frequently divided doses d) metabolism of medications

d) metabolism of medications

A client who was recently diagnosed with carcinoma of the pancreas and is having a procedure in which the head of the pancreas is removed. In addition, the surgeon will remove the duodenum and stomach, redirecting the flow of secretions from the stomach, gallbladder, and pancreas into the middle section of the small intestine. What procedure is this client having performed?

radical pancreatoduodenectomy Radical pancreatoduodenectomy involves removing the head of the pancreas, resecting the duodenum and stomach, and redirecting the flow of secretions from the stomach, gallbladder, and pancreas into the jejunum. Cholecystojejunostomy is a rerouting of the pancreatic and biliary drainage systems, which may be done to relieve obstructive jaundice. This measure is considered palliative only. A pancreatectomy is the surgical removal of the pancreas. A pancreatectomy may be total, in which case the entire organ is removed, usually along with the spleen, gallbladder, common bile duct, and portions of the small intestine and stomach. A distal pancreatectomy is a surgical procedure to remove the bottom half of the pancreas.

A client with acute liver failure exhibits confusion, a declining level of consciousness, and slowed respirations. The nurse finds him very difficult to arouse. The diagnostic information which best explains the client's behavior is: a) elevated blood urea nitrogen and creatinine levels and hyperglycemia. b) subnormal clotting factors and platelet count. c) elevated liver enzymes and low serum protein level. d) subnormal serum glucose and elevated serum ammonia levels.

A nurse in the surgical ICU just received a client from recovery following a Whipple procedure. Which of the following nursing diagnoses should the nurse consider when caring for this acutely ill client? Select all that apply. a) Alterations in respiratory function b) Acute pain and discomfort c) Potential for infection d) Fluid volume excess

• Alterations in respiratory function • Acute pain and discomfort • Potential for infection Monitor for potential for infection related to invasive procedure and poor physical condition. Monitor for pain related to extensive surgical incision. Monitor for alterations in respiratory function related to extensive surgical incisions, immobility, and prolonged anesthesia. Client is at risk for fluid volume deficit related to hemorrhage and loss of fluids.

Patient with metabolic liver dysfunction can have exhibit involuntary flapping movement of the hands, what is this called?

Asterixis

The nurse is caring for a patient with cirrhosis of the liver and observes that the patient is having hand-flapping tremors. What does the nurse document this finding as?

Asterixis

Octreotide (Sandostatin) Octreotide (Sandostatin), a synthetic analogue of the hormone somatostatin, is effective in decreasing bleeding from esophageal varices, and lacks the vasoconstrictive effects of vasopressin. Because of this safety and efficacy profile, octreotide is considered the preferred treatment regimen for immediate control of variceal bleeding.

A client with acute pancreatitis has jaundice with diminished bowel sounds and a tender distended abdomen. Additionally, lab results indicate hypovolemia. What will the physician order to treat the large amount of protein-rich fluid that has been released into the client's tissues and peritoneal cavity? Select all that apply.

diuretics albumin (Diuretics are given if circulating fluid is excessive. IV albumin may be given to pull fluid trapped in the peritoneum back into the circulation.)

Timothy is a client being treated for hepatitis in the infectious disease office where you practice nursing. He has a history of IV drug use. He presents today with jaundice and arthralgias. Timothy most likely has which type of hepatitis? a) Hepatitis A b) Hepatitis E c) Hepatitis B d) Hepatitis C

Hepatitis B Mode of transmission is from infected blood or plasma, needles, syringes, surgical or dental equipment contaminated with infected blood; also sexually transmitted through vaginal secretions and semen of carriers or those actively infected. Mode of transmission is similar to HBV, although less severe and without jaundice. The client's presentation is most similar to hepatitis B. Mode of transmission is the oral route from feces and saliva of infected persons. The client's presentation is most similar to hepatitis B. Mode of transmission is similar to HAV. The client's presentation is most similar to hepatitis B.

The nurse should suspect which situation? a) The client is relaxed and not in pain. b) The client is avoiding the nurse. c) The client's hepatic function is decreasing. d) The client didn't take his morning dose of lactulose (Cephulac).

c) The client's hepatic function is decreasing.

Nurse Assesses the Patient for Physical signs that may occur with Liver Dysfunction - Name them

i.e., pallor often seen with chronic illness and jaundice. The skin, mucosa, and sclerae are inspected for jaundice, and the extremities are assessed for muscle atrophy, edema, and skin excoriation secondary to scratching. The nurse observes the skin for petechiae or ecchymotic areas (bruises), spider angiomas (Fig. 49-3), and palmar erythema. The male patient is assessed for unilateral or bilateral gynecomastia and testicular atrophy due to hormonal changes. The patient's cognitive status (recall, memory, abstract thinking) and neurologic status are assessed. The nurse observes for general tremor, asterixis, weakness, and slurred speech.

A client with viral hepatitis A is being treated in an acute care facility. Because the client requires enteric precautions, the nurse should:

wash her hands after touching the client

A nursing student is reviewing for an upcoming anatomy and physiology examination. Which of the following would the student correctly identify as a function of the liver? Select all that apply.

• Ammonia conversion • Glucose metabolism • Protein metabolism

You must have the second one in 1 month and the third in 6 months." Both forms of the hepatitis B vaccine are administered intramuscularly in three doses; the second and third doses are given 1 and 6 months, respectively, after the first dose.

A client with a lengthy history of alcohol addiction is being seen for jaundice. The appearance of jaundice would most likely indicate: a) liver disorder. b) glucose underproduction. c) bile overproduction. d) gallbladder disease.

a) liver disorder.

Total parental nutrition (TPN) should be used cautiously in clients with pancreatitis because such clients: a) are at risk for hepatic encephalopathy. b) cannot tolerate high-glucose concentration. c) can digest high-fat foods. d) are at risk for gallbladder contraction.

b) cannot tolerate high-glucose concentration.

Total parental nutrition (TPN) should be used cautiously in clients with pancreatitis because such clients:

cannot tolerate high-glucose concentration.

A nurse is caring for a client with cholelithiasis. Which sign indicates obstructive jaundice? Straw-colored urine Reduced hematocrit Clay-colored stools Elevated urobilinogen in the urine

clay colored stools

A client with a lengthy history of alcohol addiction is being seen for jaundice. The appearance of jaundice would most likely indicate:

liver disorder.

The nurse is preparing to interview a client with cirrhosis. Based on an understanding of this disorder, which question would be most important to include?

"How often do you drink alcohol?" The most common type of cirrhosis results from chronic alcohol intake and is frequently associated with poor nutrition. Although it can follow chronic poisoning with chemicals or ingestion of hepatotoxic drugs such as acetaminophen, asking about alcohol intake would be most important. Asking about an infection or exposure to hepatotoxins or industrial chemicals would be important if the client had postnecrotic cirrhosis.

While conducting a physical examination of a client, which of the following skin findings would alert the nurse to the possibility of liver problems? Select all that apply.

- Jaundice - Petechiae - Ecchymoses

A client has received a diagnosis of portal hypertension. What does portal hypertension treatment aim to reduce? Select all that apply.

Functions of the Liver

.Glucose Metabolism, Ammonia Conversion, Protein Metabolism, Fat Metabolism, Vitamin and Iron Storage, Bile Formation, Bilirubin Excretion, Drug Metabolism

A nurse assesses a patient diagnosed with hepatic encephalopathy. She observes a number of clinical signs, including asterixis and fetor hepaticus; the patient's electroencephalogram (EEG) is abnormal. The nurse documents that the patient is exhibiting signs of which stage of hepatic encephalopathy? Stage 1 Stage 2 Stage 3 Stage 4

Acetaminophen Ketoconazole Valproic acid

Albumin

Circulatory changes within a diseased liver can caused this condition?

Ascites results from circulatory changes within the diseased liver.

Hepatic Disorders Assessment

Assess for physical signs of indigestion, reflux, hemorrhoids, gallstones, intolerance to fatty foods, intolerance to alcohol, nausea and vomiting attacks, abdominal bloating, and constipation. • Assess for associated nervous system disorders such as depression and mood changes, especially anger and irritability. • Assess for associated blood sugar problems such as hypoglycemia.

The nurse is caring for a patient with cirrhosis of the liver and observes that the patient is having hand-flapping tremors. What does the nurse document this finding as?

Asterixis. Asterixis, an involuntary flapping of the hands, may be seen in stage II encephalopathy

A nurse is caring for a client with cholelithiasis. Which sign indicates obstructive jaundice?

Clay-colored stools Obstructive jaundice develops when a stone obstructs the flow of bile in the common bile duct. When the flow of bile to the duodenum is blocked, the lack of bile pigments results in a clay-colored stool. In obstructive jaundice, urine tends to be dark amber (not straw-colored) as a result of soluble bilirubin in the urine. Hematocrit levels aren't affected by obstructive jaundice. Because obstructive jaundice prevents bilirubin from reaching the intestine (where it's converted to urobilinogen), the urine contains no urobilinogen.

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.

Which of the following is an age-related change of the hepatobiliary system? a) Decreased prevalence of gallstones b) Decreased blood flow c) Increased drug clearance capability d) Liver enlargement

Decreased blood flow Explanation: Age-related changes of the hepatobiliary system include decreased blood flow, decreased drug clearance capability, increased presence of gall stones, and a steady decrease in size and weight of the liver.

Symptoms That Suggest Liver Disease

Symptoms that may have their origin in liver disease but are not specific to hepatic dysfunction include jaundice, malaise, weakness, fatigue, pruritus, abdominal pain, fever, anorexia, weight gain, edema, increasing abdominal girth, hematemesis, melena, hematochezia (passage of bloody stools), easy bruising, changes in mental acuity, personality changes, sleep disturbances, and decreased libido in men and secondary amenorrhea in women.

A client is given a diagnosis of hepatic cirrhosis. The client asks the nurse what findings led to this determination. Which of the following clinical manifestations would the nurse correctly identify? Select all that apply. -Enlarged liver size -Ascites -Accelerated behaviors and mental processes -Hemorrhoids -Excess storage of vitamin C

Enlarged liver size Ascites Hemorrhoids Early in the course of cirrhosis, the liver tends to be large, and the cells are loaded with fat. The liver is firm and has a sharp edge that is noticeable on palpation. Portal obstruction and ascites, late manifestations of cirrhosis, are caused partly by chronic failure of liver function and partly by obstruction of the portal circulation. The obstruction to blood flow through the liver caused by fibrotic changes also results in the formation of collateral blood vessels in the GI system and shunting of blood from the portal vessels into blood vessels with lower pressures. These distended blood vessels form varices or hemorrhoids, depending on their location. Because of inadequate formation, use, and storage of certain vitamins (notably vitamins A, C, and K), signs of deficiency are common, particularly hemorrhagic phenomena associated with vitamin K deficiency. Additional clinical manifestations include deterioration of mental and cognitive function with impending hepatic encephalopathy and hepatic coma, as previously described.

The mode of transmission of hepatitis A virus (HAV) includes which of the following? a) Fecal-oral b) Blood c) Semen d) Saliva

Fecal-oral Explanation: The mode of transmission of hepatitis A virus (HAV) occurs through fecal-oral route, primarily through person to person contact and/or ingestion of fecal contaminated food or water. Hepatitis B virus (HBV) is transmitted primarily through blood. HBV can be found in blood, saliva, semen, and can be transmitted through mucous membranes and breaks in the skin.

Which type of deficiency results in microcytic anemia? Microcytic anemia is: Red Blood Cells smaller than normal. Look for iron deficiency for cause.

Folic Acid - B Vitamin. foods - beans, asparagus, beets, broccoli, brussels sprouts, spinach, oranges, whole wheat products. Folic acid deficiency results in macrocytic anemia. Vitamin C deficiency results in hemorrhagic lesions of scurvy. Vitamin A deficiency results in night blindness and eye and skin changes. Vitamin K deficiency results in hypoprothrombinemia, which is characterized by spontaneous bleeding and ecchymosis.

The nurse identifies which of the following types of jaundice in an adult experiencing a transfusion reaction? a) Hemolytic b) Nonobstructive c) Hepatocellular d) Obstructive

Hemolytic Hemolytic jaundice occurs because, although the liver is functioning normally, it cannot excrete the bilirubin as quickly as it is formed. This type of jaundice is encountered in patients with hemolytic transfusion reactions and other hemolytic disorders. Obstructive jaundice is the result of liver disease. Nonobstructive jaundice occurs with hepatitis. Hepatocellular jaundice is the result of liver disease.

A client and spouse are visiting the clinic. The client recently experienced a seizure and says she has been having difficulty writing. Before the seizure, the client says that for several weeks she was sleeping late into the day but having restlessness and insomnia at night. The client's husband says that he has noticed the client has been moody and slightly confused. Which of the following problems is most consistent with the client's clinical manifestations?

Hepatic encephalopathy

A patient has an elevated serum ammonia level and is exhibiting mental status changes. The nurse should suspect which of the following conditions? a) Hepatic encephalopathy b) Portal hypertension c) Asterixis d) Cirrhosis

Hepatic encephalopathy Hepatic encephalopathy is a central nervous system dysfunction resulting from liver disease. It is frequently associated with elevated ammonia levels that produce changes in mental status, altered level of consciousness, and coma. Portal hypertension is an elevated pressure in the portal circulation resulting from obstruction of venous flow into and through the liver. Asterixis is an involuntary flapping movement of the hands associated with metabolic liver dysfunction.

A 33-year-old male patient with a history of IV heroin and cocaine use has been admitted to the medical unit for the treatment of endocarditis. The nurse should recognize that this patient is also likely to test positive for which of the following hepatitis viruses?

Hepatitis C. Transmission of hepatitis C occurs primarily through injection of drugs and through transfusion of blood products prior to 1992

Patients diagnosed with esophageal varices are at risk for hemorrhagic shock. Which of the following is a sign of potential hypovolemia?

Hypotension

Patients diagnosed with esophageal varices are at risk for hemorrhagic shock. Which of the following is a sign of potential hypovolemia? a) Bradycardia b) Warm moist skin c) Hypotension d) Polyuria

Hypotension Explanation: Signs of potential hypovolemia include cool, clammy skin, tachycardia, decreased blood pressure, and decreased urine output.

Liver function test - GGT-

Increased GGT levels are associated with cholestasis but can also be due to alcoholic liver disease. Although the kidney has the highest level of the enzyme, the liver is considered the source of normal serum activity. The test determines liver cell dysfunction and is a sensitive indicator of cholestasis. Its main value in liver disease is confirming the hepatic origin of an elevated alkaline phosphatase level.

A nurse is preparing a presentation for a local community group about hepatitis. Which of the following would the nurse include? Hepatitis B is transmitted primarily by the oral-fecal route. Hepatitis A is frequently spread by sexual contact. Hepatitis C increases a person's risk for liver cancer. Infection with hepatitis G is similar to hepatitis A.

While conducting a physical examination of a client, which of the following skin findings would alert the nurse to the possibility of liver problems? Select all that apply. Jaundice Petechiae Ecchymoses Cyanosis of the lips Aphthous stomatitis

Jaundice Petechiae Ecchymoses

While conducting a physical examination of a client, which of the following skin findings would alert the nurse to the possibility of liver problems? Select all that apply.

Jaundice, Petechiae, Ecchymoses The skin, mucosa, and sclerae are inspected for jaundice. The nurse observes the skin for petechiae or ecchymotic areas (bruises), spider angiomas, and palmar erythema. Cyanosis of the lips is indicative of a problem with respiratory or cardiovascular dysfunction. Aphthous stomatitis is a term for mouth ulcers and is a gastrointestinal abnormal finding.

Loss of 2.2 lb (1 kg) in 24 hours

A physician orders spironolactone (Aldactone), 50 mg by mouth four times daily, for a client with fluid retention caused by cirrhosis. Which finding indicates that the drug is producing a therapeutic effect? a) Serum sodium level of 135 mEq/L b) Blood pH of 7.25 c) Serum potassium level of 3.5 mEq/L d) Loss of 2.2 lb (1 kg) in 24 hours

Loss of 2.2 lb (1 kg) in 24 hours Explanation: Daily weight measurement is the most accurate indicator of fluid status; a loss of 2.2 lb (1 kg) indicates loss of 1 L of fluid. Because spironolactone is a diuretic, weight loss is the best indicator of its effectiveness. This client's serum potassium and sodium levels are normal. A blood pH of 7.25 indicates acidosis, an adverse reaction to spironolactone.

Maintaining the airway Esophageal varices are almost always caused by portal hypertension, which results from obstruction of the portal circulation within the damaged liver. Maintaining the airway is the highest priority because oxygenation is essential for life. The airway can be compromised by possible displacement of the tube and the inflated balloon into the oropharynx, which can cause life-threatening obstruction of the airway and asphyxiation.

When performing a physical examination on a client with cirrhosis, a nurse notices that the client's abdomen is enlarged. Which of the following interventions should the nurse consider?

Measure abdominal girth according to a set routine

Which is the most common cause of esophageal varices?

Portal Hypertension. Esophageal varices are almost always caused by portal hypertension, which results from obstruction of the portal circulation within the damaged liver. Jaundice occurs when the bilirubin concentration in the blood is abnormally elevated. Ascites results from circulatory changes within the diseased liver. Asterixis is an involuntary flapping movement of the hands associated with metabolic liver dysfunction.

The nurse is providing care to a patient with gross ascites who is maintaining a position of comfort in the high semi-Fowler's position. What is the nurse's priority assessment of this patient?

Respiratory assessment related to increased thoracic pressure ------If a patient with ascites from liver dysfunction is hospitalized, nursing measures include assessment and documentation of intake and output (I&O;), abdominal girth, and daily weight to assess fluid status. The nurse also closely monitors the respiratory status because large volumes of ascites can compress the thoracic cavity and inhibit adequate lung expansion. The nurse monitors serum ammonia, creatinine, and electrolyte levels to assess electrolyte balance, response to therapy, and indications of encephalopathy.

After undergoing a liver biopsy, a client should be placed in which position?

Right lateral decubitus position

Alcohol intake amounts lead to Cirrhosis

The amount of alcohol required to produce chronic liver disease varies widely, but men who consume 60 to 80 g/day of alcohol (approximately four glasses of beer, wine, or mixed drinks) and women whose alcohol intake is 40 to 60 g/day are considered at high risk for cirrhosis.

A patient with hepatic cirrhosis questions the nurse about the possible use of an herbal supplement—milk thistle—to help heal the liver. Which of the following would be the most appropriate response from the nurse? You should not use herbal supplements in conjunction with medical treatment. Herbal supplements are approved by the FDA, so there should be no problem with their usage if you check with your primary care provider. Silymarin from milk thistle has anti-inflammatory and antioxidant properties that may have beneficial effects, especially in hepatitis.However, you should always notify your primary care provider of any herbal remedies being used so drug interactions can be evaluated. You can use milk thistle instead of the medications you have been prescribed.

Which of the following medications would the nurse expect the physician to order for a client with cirrhosis who develops portal hypertension?

Spironolactone (Aldactone)

Gynecomastia is a common side effect of which of the following diuretics? -Spironolactone (Aldactone) -Furosemide (Lasix) -Vasopressin (Pitressin) -Nitroglycerin (IV

Spironolactone (Aldactone) Gynecomastia is a common side effect caused by spironolactone. Pitressin is used for bleeding esophageal varices and is not a diuretic. Nitroglycerin (IV) may be used with vasopressin to counteract the effects of vasoconstriction from the vasopressin.

The nurse is concerned about potassium loss when a diuretic is prescribed for a patient with ascites and edema. What diuretic may be ordered that spares potassium and prevents hypokalemia? a)Bumetanide (Bumex) b)Furosemide (Lasix) c)Acetazolamide (Diamox) d)Spironolactone (Aldactone)

Spironolactone (Aldactone) Potassium-sparing diuretic agents such as spironolactone or triamterene (Dyrenium) may be indicated to decrease ascites, if present; these diuretics are preferred because they minimize the fluid and electrolyte changes commonly seen with other agents.

A patient with severe chronic liver dysfunction comes to the clinic with bleeding of the gums and blood in the stool. What vitamin deficiency does the nurse suspect the patient may be experiencing?

Vitamin K deficiency

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
