chapter 46 Flashcards
A client contracts hepatitis from contaminated food. During the acute (icteric) phase of the
client’s illness, which of the following serological findings should the nurse expect?
a. Antibody to hepatitis D virus (anti-HDV)
b. Hepatitis B surface antigen (HBsAg)
c. Anti-hepatitis A virus immunoglobulin G (anti-HAV IgG)
d. Anti-hepatitis A virus immunoglobulin M (anti-HAV IgM)
D
Hepatitis A is transmitted through the oral–fecal route, and antibody to HAV IgM appears
during the acute phase of hepatitis A. The client would not have antigen for hepatitis B or
antibody for hepatitis D. Anti-HAV IgG would indicate past infection and lifelong
immunity.
Which of the following findings in a blood specimen indicates that the administration of
hepatitis B vaccine to a client has been effective?
a. HBsAg
b. Anti-HBs
c. Anti-HBc IgG
d. Anti-HBc IgM
B
The presence of surface antibody to HBV (anti-HBs) is a marker of a positive response to
the vaccine. The other laboratory values indicate current infection with HBV.
A client in the outpatient clinic is diagnosed with acute hepatitis C virus (HCV) infection.
Which of the following actions by the nurse is best?
a. Schedule the client for HCV genotype testing.
b. Administer immune globulin and the HCV vaccine.
c. Instruct the client on ribavirin treatment.
d. Teach that the infection will resolve in a few months.
A
Genotyping of HCV has an important role in managing treatment and is done before drug
therapy is initiated. Since most clients with acute HCV infection convert to the chronic
state, the nurse should not teach the client that the HCV will resolve in a few months.
Immune globulin or vaccine is not available for HCV. Ribavirin is used for chronic HCV
infection.
The nurse is caring for a client who is diagnosed with acute hepatitis B. Which of the
following information should the nurse include in the teaching plan?
a. Ways to increase exercise and activity level
b. Self-administration of a-interferon
c. Adverse effects of nucleoside and nucleotide analogs
d. Measures that will be helpful in improving appetite
D
Maintaining adequate nutritional intake is important for regeneration of hepatocytes.
Interferon and antivirals may be used for chronic hepatitis B, but they are not prescribed
for acute hepatitis B infection. Rest is recommended.
The nurse is caring for a client with chronic hepatitis C who is prescribed combination
therapy of a-interferon and ribavirin. Which of the following findings should the nurse
monitor for the presence of hepatitis C in the client?
a. Leukopenia
b. Hypokalemia
c. Polycythemia
d. Hypoglycemia
A
Therapy with ribavirin and a-interferon may cause leukopenia. The other problems are not
associated with this drug therapy.
Which of the following clients should alert the nurse that screening for hepatitis C should
be done?
a. The client eats frequent meals in fast-food restaurants.
b. The client recently travelled to an undeveloped country.
c. The client had a blood transfusion after surgery in 1998.
d. The client reports a one-time use of IV drugs 20 years ago.
D
Any client with a history of IV drug use should be tested for hepatitis C. Blood
transfusions given after 1992, when an antibody test for hepatitis C became available, do
not pose a risk for hepatitis C. Hepatitis C is not spread by the oral–fecal route and
therefore is not caused by contaminated food or by travelling in underdeveloped countries.
The nurse is caring for a client who is admitted with an abrupt onset of jaundice, nausea,
and abnormal liver function studies. Serological testing is negative for viral causes of
hepatitis. Which of the following questions by the nurse is best?
a. “Is there any history of IV drug use?”
b. “Are you taking corticosteroids for any reason?”
c. “Do you use any over-the-counter (OTC) drugs?”
d. “Have you recently travelled to a foreign country?”
C
The client’s symptoms, lack of antibodies for hepatitis, and the abrupt onset of symptoms
suggest toxic hepatitis, which can be caused by commonly used OTC drugs such as
acetaminophen. Travel to a foreign country and a history of IV drug use are risk factors for
viral hepatitis. Corticosteroid use does not cause the symptoms listed.
The nurse is caring for a client with cirrhosis who has 4+ pitting edema of the feet and legs.
Which of the following assessments is priority for the nurse to monitor?
a. Hemoglobin
b. Temperature
c. Activity level
d. Albumin
D
The low oncotic pressure caused by hypoalbuminemia is a major pathophysiological factor
in the development of edema. The other parameters also should be monitored, but they are
not directly associated with the client’s current symptoms.
The nurse is preparing a teaching plan for a young adult client who is diagnosed with early
alcoholic cirrhosis. Which of the following topics is most important to include in client
teaching?
a. Need to abstain from alcohol
b. Use of vitamin B supplements
c. Maintenance of a nutritious diet
d. Treatment with lactulose
A
The disease progression can be stopped or reversed by alcohol abstinence. The other
interventions may be used when cirrhosis becomes more severe to decrease symptoms or
complications, but the priority for this client is to stop the progression of the disease.
The nurse is caring for a client with cirrhosis who has scheduled doses of spironolactone
and furosemide and has a serum potassium level of 3.2 mmol/L. Which of the following
actions should the nurse take?
a. Give both drugs as scheduled.
b. Administer the spironolactone.
c. Administer the furosemide and withhold the spironolactone.
d. Withhold both drugs until talking with the health care provider.
B
Spironolactone is a potassium-sparing diuretic and will help to increase the client’s
potassium level. The nurse does not need to talk with the doctor before giving the
spironolactone, although the health care provider should be notified about the low
potassium value. The furosemide will further decrease the client’s potassium level and
should be held until the nurse talks with the health care provider.
Which of the following actions should the nurse implement to evaluate the effectiveness of
treatment for a client who has hepatic encephalopathy?
a. Request that the client stand on one foot.
b. Ask the client to extend both arms to the front.
c. Instruct the client to perform the Valsalva manoeuvre.
d. Have the client walk a few steps with the eyes closed.
B
Extending the arms allows the nurse to check for asterixis, a classic sign of hepatic
encephalopathy. The other tests also might be done as part of the neurological assessment
but would not be diagnostic for hepatic encephalopathy.
The nurse is caring for a client who has advanced cirrhosis and is receiving lactulose.
Which of the following findings by the nurse indicates that the medication is effective?
a. The client is alert and oriented.
b. The client denies nausea or anorexia.
c. The client’s bilirubin level decreases.
d. The client has at least one stool daily.
A
The purpose for lactulose in the client with cirrhosis is to lower ammonia levels and
prevent encephalopathy. Although lactulose may be used to treat constipation, that is not
the purpose for this client. Lactulose will not decrease nausea and vomiting or lower
bilirubin levels.
Which of the following nursing actions should be included in the plan of care for a client
who is being treated for bleeding esophageal varices with balloon tamponade?
a. Monitor the client for shortness of breath.
b. Encourage the client to cough every 4 hours.
c. Deflate the gastric balloon every 8–12 hours.
d. Verify the position of the balloon every 6 hours.
A
A common complication of balloon tamponade is occlusion of the airway by the balloon
so it is important to monitor the client’s respiratory status. In addition, if the gastric
balloon ruptures, the esophageal balloon may slip upward and occlude the airway.
Coughing increases the pressure on the varices and increases the risk for bleeding. Balloon
position is verified after insertion and does not require further verification. The esophageal
balloon is deflated every 8–12 hours to avoid necrosis, but if the gastric balloon is deflated,
the esophageal balloon may occlude the airway.
The nurse is caring for a client with severe cirrhosis who has an episode of bleeding
esophageal varices. Which of the following laboratory tests should the nurse monitor to
detect possible complications of the bleeding episode?
a. Bilirubin
b. Ammonia
c. Potassium
d. Prothrombin time
B
The blood in the gastrointestinal (GI) tract will be absorbed as protein and may result in an
increase in ammonia level because the liver cannot metabolize protein well. The
prothrombin time, bilirubin, and potassium levels also should be monitored, but these will
not be affected by the bleeding episode.
Which of the following nursing actions should be included in the plan of care for a client
with cirrhosis who has ascites and 4+ edema of the feet and legs?
a. Weekly weight of client
b. Reposition the client every 4 hours
c. Restrict sodium intake.
d. Perform passive range-of-motion QID.
C
To maintain skin integrity, restrict sodium intake as ordered to prevent additional fluid
retention. The client should be weighed daily, not weekly. Repositioning the client every 4
hours will not be adequate to maintain skin integrity; clients should be repositioned at least
every two hours. Passive range of motion will not take pressure off areas like the sacrum
that are vulnerable to breakdown.
