◉ A young adult contracts hepatitis from contaminated food. Which
result would the nurse expect serologic testing to reveal during the
acute (icteric) phase of the patient's illness?
1. Antibody to hepatitis D (anti-HDV)
2. Hepatitis B surface antigen (HBsAg)
3. Anti-hepatitis A virus immunoglobulin G (anti-HAV IgG)
4. Anti-hepatitis A virus immunoglobulin M (anti-HAV IgM). Answer:
4. Anti-hepatitis A virus immunoglobulin M (anti-HAV IgM)
Hepatitis A is transmitted through the oral-fecal route, and antibody
to HAV IgM appears during the acute phase of hepatitis A. The
patient would not have antigen for hepatitis B or antibody for
hepatitis D. Anti-HAV IgG would indicate past infection and lifelong
immunity.
◉ The nurse evaluates that administration of hepatitis B vaccine to a
healthy patient was effective when the patient's later blood
specimen reveals the presence of
1. HBsAg.
,2. anti-HBs.
3. anti-HBc IgG.
4. anti-HBc IgM.. Answer: 2. anti-HBs.
The presence of surface antibody to hepatitis B (anti-HBs) is a
marker of a positive response to the vaccine or previous illness with
hepatitis B. The other laboratory values indicate current infection
with hepatitis B.
◉ A patient in the outpatient clinic is diagnosed with acute hepatitis
C (HCV) infection. Which action would the nurse take?
1. Schedule the patient for HCV genotype testing.
2. Administer the HCV vaccine and immune globulin.
3. Teach the patient about direct-acting antiviral treatment.
4. Explain that the infection will resolve over a few months.. Answer:
1. Schedule the patient for HCV genotype testing.
Genotyping of HCV has an important role in managing treatment and
is done before drug therapy is initiated. Because most patients with
acute HCV infection convert to the chronic state, the nurse should
not teach the patient that the HCV will resolve in a few months.
Immune globulin or vaccine is not available for HCV. Direct-acting
antiviral drugs are used for chronic HCV infection.
, ◉ Which topic would the nurse plan to teach the patient diagnosed
with acute hepatitis B?
1. Administering a-interferon
2. Measures for improving appetite
3. Side effects of nucleotide analogs
4. Ways to increase activity and exercise. Answer: 2. Measures for
improving appetite
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.
◉ Which information from a 70-yr-old patient during a health
history indicates to the nurse that the patient should be screened for
hepatitis C?
1. The patient had a blood transfusion in 2005.
2. The patient used IV drugs about 30 years ago.
3. The patient frequently eats in fast-food restaurants.
4. The patient traveled to a country with poor sanitation.. Answer: 2.
The patient used IV drugs about 30 years ago.
