Chapter 35 Questions
Question 1 of 5
A patient is being treated for bacterial pneumonia. In the first stages of illness, the patients dyspnea was accompanied by a high fever. Currently, the patient claims to be feeling better and is afebrile. The patient is most likely in which stage of the immune response?
Correct Answer: D
Rationale: The immune response culminates with the effector stage, during which offending microorganisms are killed by the various actions of the immune system. The patients improvement in health status is likely the result of this final stage in the immune response.
Question 2 of 5
A nursing student is giving a report on the immune system. What function of cytokines should the student describe?
Correct Answer: D
Rationale: Separate subpopulations of helper T cells produce different types of cytokines and determine whether the immune response will be the production of antibodies or a cell-mediated immune response. Cytokines do not determine whether cells are foreign, determine if lymphokines will be activated, or determine the role of memory T cells.
Question 3 of 5
A nurse has administered a childs scheduled vaccination for rubella. This vaccination will cause the child to develop which of the following?
Correct Answer: B
Rationale: Active acquired immunity usually develops as a result of vaccination or contracting a disease. Natural immunity is present at birth and provides a nonspecific response to any foreign invader. Immunizations do not activate the process of cellular immunity. Hypersensitivity is not an expected outcome of immunization.
Question 4 of 5
A patient was recently exposed to infectious microorganisms and many T lymphocytes are now differentiating into killer T cells. This process characterizes what stage of the immune response?
Correct Answer: B
Rationale: In the proliferation stage, T lymphocytes differentiate into cytotoxic (or killer) T cells, whereas B lymphocytes produce and release antibodies. This does not occur in the response, recognition, or effector stages.
Question 5 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.
