Brunner's Ch 49: Assessment and Management of Patients with Hepatic Disorders Flashcards
A nurse is caring for a patient with liver failure and is performing an assessment in the knowledge of the patients increased risk of bleeding. The nurse recognizes that this risk is related to the patients inability to synthesize prothrombin in the liver. What factor most likely contributes to this loss of function?
A) Alterations in glucose metabolism
B) Retention of bile salts
C) Inadequate production of albumin by hepatocytes
D) Inability of the liver to use vitamin K
D) Inability of the liver to use vitamin K
Decreased production of several clotting factors may be partially due to deficient absorption of vitamin K from the GI tract. This probably is caused by the inability of liver cells to use vitamin K to make prothrombin. This bleeding risk is unrelated to the roles of glucose, bile salts, or albumin.
A nurse is performing an admission assessment of a patient with a diagnosis of cirrhosis. What technique should the nurse use to palpate the patients liver?
A) Place hand under the right lower abdominal quadrant and press down lightly with the other hand.
B) Place the left hand over the abdomen and behind the left side at the 11th rib.
C) Place hand under right lower rib cage and press down lightly with the other hand.
D) Hold hand 90 degrees to right side of the abdomen and push down firmly.
C) Place hand under right lower rib cage and press down lightly with the other hand.
To palpate the liver, the examiner places one hand under the right lower rib cage and presses downward with light pressure with the other hand. The liver is not on the left side or in the right lower abdominal quadrant.
A patient with portal hypertension has been admitted to the medical floor. The nurse should prioritize which of the following assessments related to the manifestations of this health problem?
A) Assessment of blood pressure and assessment for headaches and visual changes
B) Assessments for signs and symptoms of venous thromboembolism
C) Daily weights and abdominal girth measurement
D) Blood glucose monitoring q4h
C) Daily weights and abdominal girth measurement
Obstruction to blood flow through the damaged liver results in increased blood pressure (portal hypertension) throughout the portal venous system. This can result in varices and ascites in the abdominal cavity. Assessments related to ascites are daily weights and abdominal girths. Portal hypertension is not synonymous with cardiovascular hypertension and does not create a risk for unstable blood glucose or VTE.
A nurse educator is teaching a group of recent nursing graduates about their occupational risks for contracting hepatitis B. What preventative measures should the educator promote? Select all that apply. A) Immunization B) Use of standard precautions C) Consumption of a vitamin-rich diet D) Annual vitamin K injections E) Annual vitamin B12 injections
A) Immunization
B) Use of standard precautions
People who are at high risk, including nurses and other health care personnel exposed to blood or blood products, should receive active immunization. The consistent use of standard precautions is also highly beneficial. Vitamin supplementation is unrelated to an individuals risk of HBV.
A nurse is caring for a patient with cancer of the liver whose condition has required the insertion of a percutaneous biliary drainage system. The nurses most recent assessment reveals the presence of dark green fluid in the collection container. What is the nurses best response to this assessment finding?
A) Document the presence of normal bile output.
B) Irrigate the drainage system with normal saline as ordered.
C) Aspirate a sample of the drainage for culture.
D) Promptly report this assessment finding to the primary care provider.
A) Document the presence of normal bile output.
Bile is usually a dark green or brownish-yellow color, so this would constitute an expected assessment finding, with no other action necessary.
A patient who has undergone liver transplantation is ready to be discharged home. Which outcome of health education should the nurse prioritize?
A) The patient will obtain measurement of drainage from the T-tube.
B) The patient will exercise three times a week.
C) The patient will take immunosuppressive agents as required.
D) The patient will monitor for signs of liver dysfunction.
C) The patient will take immunosuppressive agents as required.
The patient is given written and verbal instructions about immunosuppressive agent doses and dosing schedules. The patient is also instructed on steps to follow to ensure that an adequate supply of medication is available so that there is no chance of running out of the medication or skipping a dose. Failure to take medications as instructed may precipitate rejection. The nurse would not teach the patient to measure drainage from a T-tube as the patient wouldnt go home with a T-tube. The nurse may teach the patient about the need to exercise or what the signs of liver dysfunction are, but the nurse would not stress these topics over the immunosuppressive drug regimen.
A triage nurse in the emergency department is assessing a patient who presented with complaints of general malaise. Assessment reveals the presence of jaundice and increased abdominal girth. What assessment question best addresses the possible etiology of this patients presentation?
A) How many alcoholic drinks do you typically consume in a week?
B) To the best of your knowledge, are your immunizations up to date?
C) Have you ever worked in an occupation where you might have been exposed to toxins?
D) Has anyone in your family ever experienced symptoms similar to yours?
A) How many alcoholic drinks do you typically consume in a week?
Signs or symptoms of hepatic dysfunction indicate a need to assess for alcohol use. Immunization status, occupational risks, and family history are also relevant considerations, but alcohol use is a more common etiologic factor in liver disease.
A nurse is participating in the emergency care of a patient who has just developed variceal bleeding. What intervention should the nurse anticipate?
A) Infusion of intravenous heparin
B) IV administration of albumin
C) STAT administration of vitamin K by the intramuscular route
D) IV administration of octreotide (Sandostatin)
D) IV administration of octreotide (Sandostatin)
Octreotide (Sandostatin)a synthetic analog of the hormone somatostatinis 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. Vitamin K and albumin are not administered and heparin would exacerbate, not alleviate, bleeding.
A nurse is caring for a patient with hepatic encephalopathy. While making the initial shift assessment, the nurse notes that the patient has a flapping tremor of the hands. The nurse should document the presence of what sign of liver disease? A) Asterixis B) Constructional apraxia C) Fetor hepaticus D) Palmar erythema
A) Asterixis
The nurse will document that a patient exhibiting a flapping tremor of the hands is demonstrating asterixis. While constructional apraxia is a motor disturbance, it is the inability to reproduce a simple figure. Fetor hepaticus is a sweet, slightly fecal odor to the breath and not associated with a motor disturbance. Skin changes associated with liver dysfunction may include palmar erythema, which is a reddening of the palms, but is not a flapping tremor.
A local public health nurse is informed that a cook in a local restaurant has been diagnosed with hepatitis A. What should the nurse advise individuals to obtain who ate at this restaurant and have never received the hepatitis A vaccine? A) The hepatitis A vaccine B) Albumin infusion C) The hepatitis A and B vaccines D) An immune globulin injection
D) An immune globulin injection
For people who have not been previously vaccinated, hepatitis A can be prevented by the intramuscular administration of immune globulin during the incubation period, if given within 2 weeks of exposure. Administration of the hepatitis A vaccine will not protect the patient exposed to hepatitis A, as protection will take a few weeks to develop after the first dose of the vaccine. The hepatitis B vaccine provides protection again the hepatitis B virus, but plays no role in protection for the patient exposed to hepatitis A. Albumin confers no therapeutic benefit.
A participant in a health fair has asked the nurse about the role of drugs in liver disease. What health promotion teaching has the most potential to prevent drug-induced hepatitis?
A) Finish all prescribed courses of antibiotics, regardless of symptom resolution.
B) Adhere to dosing recommendations of OTC analgesics.
C) Ensure that expired medications are disposed of safely.
D) Ensure that pharmacists regularly review drug regimens for potential interactions.
B) Adhere to dosing recommendations of OTC analgesics.
Although any medication can affect liver function, use of acetaminophen (found in many over-the- counter medications used to treat fever and pain) has been identified as the leading cause of acute liver failure. Finishing prescribed antibiotics and avoiding expired medications are unrelated to this disease. Drug interactions are rarely the cause of drug-induced hepatitis.
Diagnostic testing has revealed that a patients hepatocellular carcinoma (HCC) is limited to one lobe. The nurse should anticipate that this patients plan of care will focus on what intervention? A) Cryosurgery B) Liver transplantation C) Lobectomy D) Laser hyperthermia
C) Lobectomy
Surgical resection is the treatment of choice when HCC is confined to one lobe of the liver and the function of the remaining liver is considered adequate for postoperative recovery. Removal of a lobe of the liver (lobectomy) is the most common surgical procedure for excising a liver tumor. While cryosurgery and liver transplantation are other surgical options for management of liver cancer, these procedures are not performed at the same frequency as a lobectomy. Laser hyperthermia is a nonsurgical treatment for liver cancer.
A patient has been diagnosed with advanced stage breast cancer and will soon begin aggressive treatment. What assessment findings would most strongly suggest that the patient may have developed liver metastases?
A) Persistent fever and cognitive changes
B) Abdominal pain and hepatomegaly
C) Peripheral edema unresponsive to diuresis
D) Spontaneous bleeding and jaundice
B) Abdominal pain and hepatomegaly
The early manifestations of malignancy of the liver include paina continuous dull ache in the right upper quadrant, epigastrium, or back. Weight loss, loss of strength, anorexia, and anemia may also occur. The liver may be enlarged and irregular on palpation. Jaundice is present only if the larger bile ducts are occluded by the pressure of malignant nodules in the hilum of the liver. Fever, cognitive changes, peripheral edema, and bleeding are atypical signs.
A patient is being discharged after a liver transplant and the nurse is performing discharge education. When planning this patients continuing care, the nurse should prioritize which of the following risk diagnoses?
A) Risk for Infection Related to Immunosuppressant Use
B) Risk for Injury Related to Decreased Hemostasis
C) Risk for Unstable Blood Glucose Related to Impaired Gluconeogenesis
D) Risk for Contamination Related to Accumulation of Ammonia
A) Risk for Infection Related to Immunosuppressant Use
Infection is the leading cause of death after liver transplantation. Pulmonary and fungal infections are common; susceptibility to infection is increased by the immunosuppressive therapy that is needed to prevent rejection. This risk exceeds the threats of injury and unstable blood glucose. The diagnosis of Risk for Contamination relates to environmental toxin exposure.
A patient with a liver mass is undergoing a percutaneous liver biopsy. What action should the nurse perform when assisting with this procedure?
A) Position the patient on the right side with a pillow under the costal margin after the procedure.
B) Administer 1 unit of albumin 90 minutes before the procedure as ordered.
C) Administer at least 1 unit of packed red blood cells as ordered the day before the scheduled procedure.
D) Confirm that the patients electrolyte levels have been assessed prior to the procedure.
A) Position the patient on the right side with a pillow under the costal margin after the procedure.
Immediately after a percutaneous liver biopsy, assist the patient to turn onto the right side and place a pillow under the costal margin. Prior administration of albumin or PRBCs is unnecessary. Coagulation tests should be performed, but electrolyte analysis is not necessary.
A nurse is caring for a patient with hepatic encephalopathy. The nurses assessment reveals that the patient exhibits episodes of confusion, is difficult to arouse from sleep and has rigid extremities. Based on these clinical findings, the nurse should document what stage of hepatic encephalopathy? A) Stage 1 B) Stage 2 C) Stage 3 D) Stage 4
C) Stage 3
Patients in the third stage of hepatic encephalopathy exhibit the following symptoms: stuporous, difficult to arouse, sleeps most of the time, exhibits marked confusion, incoherent in speech, asterixis, increased deep tendon reflexes, rigidity of extremities, marked EEG abnormalities. Patients in stages 1 and 2 exhibit clinical symptoms that are not as advanced as found in stage 3, and patients in stage 4 are comatose. In stage 4, there is an absence of asterixis, absence of deep tendon reflexes, flaccidity of extremities, and EEG abnormalities.
