Module 5: Adaptive Immunity Exam
Questions With Verified Answers
IgE
Feedback: IgE is instrumental in the defense against parasitic infections. - Answers✔The nurse
suspects that the patient has a parasite. Which laboratory report should the nurse check to help
confirm this diagnosis?
Helper T cells
Feedback: Helper T cells stimulate the proliferation and differentiation of B and T cells, thus
exerting control over both the cell-mediated and humoral immune responses. - Answers✔A
student nurse wants to know which cells stimulate both the cell-mediated and humoral immune
responses. The nurse should identify which cells?
IL-2
Feedback: Differentiation of Tc cells also requires IL-2 produced by Th1 cells. - Answers✔For
proliferation and differentiation of Tc cells to occur, what must be present in the patient's body?
NK cells lack antigen-specificity.
Feedback: Tc cells recognize a specific antigen, whereas NK cells can recognize any infected or
malignant cell because they are not antigen specific. - Answers✔A nurse is teaching the
difference between natural killer (NK) cells and cytotoxic (Tc) cells. Which information should
the nurse include?
IgA.

Feedback: IgA, also known as secretory IgA, is found in the secretions from any mucosal
surface, including the mammary glands. It is the primary antibody found in breast milk and
confers passive acquired immunity to the breastfeeding infant. - Answers✔A new mother is
deciding whether to breast or bottle feed. She asks the nurse about the main antibody that would
be passed to her baby via breast milk. The nurse should identify this as:
IgE.
Feedback: IgE is the predominant antibody in an allergic response. - Answers✔When a person
has a life-threatening hypersensitivity/allergic reaction to bee stings, which laboratory result will
the nurse check?
active acquired immunity.
Feedback: Active acquired immunity is obtained when an individual is exposed to the antigen. -
Answers✔While taking a health history the nurse notes that the patient has resistance to a disease
as the result of natural exposure to the primary antigen. This form of immunity should be
documented as:
Epitope
Feedback: Epitope is another name for the antigenic determinant. - Answers✔When the nurse is
describing the portion of the antigenic molecule that is recognized by the lymphocyte (antigenic
determinant or antigenicity), what term should the nurse use?
cytotoxic T cells.
Feedback: Th1 cells stimulate the proliferation and differentiation of cytotoxic T cells and
macrophages. - Answers✔When a nurse is asked what Th1 cells do, how should she respond?
Th1 cells stimulate the proliferation and differentiation of:
Lymphocytes that can recognize and react to a specific antigen proliferate.
Feedback: The process of clonal selection occurs when an antigen selects those lymphocytes
with compatible receptors and expands their population. Mature lymphocytes can only recognize
one antigen. - Answers✔When explaining "clonal selection" to a group of student nurses, which
statement should the nurse include?
autoimmunity.
