Chapter 35 : Assessment of Immune Function Questions
Question 1 of 5
A patient has undergone treatment for septic shock and received high doses of numerous antibiotics during the course of treatment. When planning the patients subsequent care, the nurse should be aware of what potential effect on the patients immune function?
Correct Answer: A
Rationale: Large doses of antibiotics can precipitate bone marrow suppression, affecting immune function. Antibiotics are not noted to cause apoptosis, thymus atrophy, or lymphoma.
Question 2 of 5
A patients recent diagnostic testing included a total lymphocyte count. The results of this test will allow the care team to gauge what aspect of the patients immunity?
Correct Answer: C
Rationale: A total lymphocyte count is a test used to determine cellular immune function. It is not normally used for testing humoral immune function and the associated antigenantibody.
Question 3 of 5
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 that her bone marrow is unable to produce a sufficient amount of what?
Correct Answer: A
Rationale: The white blood cells involved in immunity (including lymphocytes) are produced in the bone marrow. Cytoblasts are the protoplasm of the cell outside the nucleus. Antibodies are produced by lymphocytes, but not in the bone marrow. Capillaries are small blood vessels.
Question 4 of 5
During a mumps outbreak at a local school, a patient, who is a school teacher, is exposed. She has previously been immunized for mumps. What type of immunity does she possess?
Correct Answer: A
Rationale: Acquired immunity usually develops as a result of prior exposure to an antigen, often through immunization. When the body is attacked by bacteria, viruses, or other pathogens, it has three means of defense. The first line of defense, the phagocytic immune response, involves the WBCs that have the ability to ingest foreign particles. A second protective response is the humoral immune response, which begins when the B lymphocytes transform themselves into plasma cells that manufacture antibodies. The natural immune response system is rapid, nonspecific immunity present at birth.
Question 5 of 5
A gardener sustained a deep laceration while working and requires sutures. The patient is asked about the date of her last tetanus shot, which is over 10 years ago. Based on this information, the patient will receive a tetanus immunization. The tetanus injection will allow for the release of what?
Correct Answer: A
Rationale: Immunizations activate the humoral immune response, culminating in antibody production. Antigens are the substances that induce the production of antibodies. Immunizations do not prompt cytokine or phagocyte production.
