A 16-year-old has been brought to the emergency department by his parents after falling through the
glass of a door. The fall resulted
... [Show More] in a 6-cm laceration of the right antecubital. The nurse caring for this
patient knows that the site of the injury will have an invasion of what?
Phagocytic cells
A gardener sustained a deep laceration while working and requires sutures. The patient is asked about
the date of his last tetanus shot, which he tells the nurse was more than 10 years ago. Based on this
information, the patient will receive a tetanus immunization. The tetanus injection will allow for the
release of what?
An antibody
Which immunoglobulin assumes a major role in bloodborne and tissue infections?
IgG
Explanation:
IgG assumes a major role in bloodborne and tissue infections. IgA protects against respiratory,
gastrointestinal, and genitourinary infections. IgM appears as the first immunoglobulin produced in
response to bacterial and viral infections. IgD possibly influences B-lymphocyte differentiation.
What specific drug group has both antiviral and anti-proliferative actions?
Interferons
Explanation:
Interferons are chemicals that are secreted by cells that have been invaded by viruses and possibly by
other stimuli. The interferons prevent viral replication and also suppress malignant cell replication and
tumor growth.
The nurse is caring for an older adult patient hospitalized with cellulitis of the right lower extremity. Why
is it imperative that the nurse continually assess the physical and emotional status of this patient?
Older adult patients develop depression and suicidal tendencies when they are faced with
chronic illness.
What types of cells are the primary targets of the healthy immune system? Select all that apply.
infectious cells
foreign cells
cancerous cells
A patient has enlarged lymph nodes in his neck and a sore throat. This inflammatory response is an
example of a cellular immune response whereby:
Lymphocytes migrate to areas of the lymph node
At 39 weeks’ gestation, a pregnant client visits the physician for a scheduled prenatal checkup. The
physician determines that the fetus has developed an infection in utero and sends the client for an
emergency cesarean delivery. The client is very concerned about the health of her unborn child. Based
on knowledge of the immune system, the delivery room nurse explains about which immunoglobulin
that will be increased in the fetus at the time of birth and will be actively fighting the infection?
IgG
Explanation:
IgG composes 75% of total immunoglobulin. It appears in serum and tissues, assumes a major role in
bloodborne and tissue infections, and crosses the placenta.
A woman has been diagnosed with breast cancer and is being treated aggressively with a
chemotherapeutic regimen. As a result of this regimen, she has an inability to fight infection due to the
fact her bone marrow is unable to produce a sufficient amount of what?
Lymphocytes
Explanation:
The white blood cells involved in immunity are produced in the bone marrow. Like other blood cells,
lymphocytes are generated from stem cells, which are undifferentiated cells. Descendants of stem cells
become lymphocytes, the B lymphocytes and the T lymphocytes. B lymphocytes mature in the bone
marrow and then enter the circulation. T lymphocytes move from the bone marrow to the thymus,
where they mature into several kinds of cells with different functions. Cytoblasts are the protoplasm of
the cell outside the nucleus. Capillaries are small blood vessels. Antibodies are protein substances that
respond to the presence of an antigen. Antibodies are found in normal circulation. [Show Less]
