Chapter 35 : Assessment of Immune Function Questions
Question 1 of 5
A patients current immune response involves the direct destruction of foreign microorganisms. This aspect of the immune response may be performed by what cells?
Correct Answer: C
Rationale: Cytotoxic T cells (also called CD8 + cells) participate in the destruction of foreign organisms. Memory T cells and suppressor T cells do not perform this role in the immune response. The complement system does not exist as a type of T cell.
Question 2 of 5
A nurse is explaining how the humoral and cellular immune responses should be seen as interacting parts of the broader immune system rather than as independent and unrelated processes. What aspect of immune function best demonstrates this?
Correct Answer: B
Rationale: T cells interact closely with B cells, indicating that humoral and cellular immune responses are not separate, unrelated processes, but rather branches of the immune response that interact. Movement of B cells does not clearly show the presence of a unified immune system. The differentiation between types of T cells and the role of the complement system do not directly suggest a single immune system.
Question 3 of 5
A nurse is caring for a patient who has had a severe antigen/antibody reaction. The nurse knows that the portion of the antigen that is involved in binding with the antibody is called what?
Correct Answer: C
Rationale: The portion of the antigen involved in binding with the antibody is referred to as the antigenic determinant. This portion is not known as an antibody lock, antigenic sequence, or antibody channel.
Question 4 of 5
A patient is being treated for cancer and the nurse has identified the nursing diagnosis of Risk for Infection Due to Protein Losses. Protein losses inhibit immune response in which of the following ways?
Correct Answer: D
Rationale: Depletion of protein reserves results in atrophy of lymphoid tissues, depression of antibody response, reduction in the number of circulating T cells, and impaired phagocytic function. This specific nutritional deficit does not cause T-cell mutation, an increase in the production of interferons, or apoptosis of cytokines.
Question 5 of 5
A patient is vigilant in her efforts to take good care of herself but is frustrated by her recent history of upper respiratory infections and influenza. What aspect of the patients lifestyle may have a negative effect on immune response?
Correct Answer: A
Rationale: Rigorous exercise or competitive exercise usually considered a positive lifestyle factor can be a physiologic stressor and cause negative effects on immune response. The patients habits around diet and sleep do not present obvious threats to immune function.
