PathoPharm1: Module 5 - Adaptive
Immunity Exam Questions With Verified
Answers
Which information should the nurse include when creating a presentation on body defenses? The
body's first line of defense against microorganisms is comprised of the: - Answers✔skin and
mucous membranes. The skin and mucous membranes (external barriers) are the first barriers
that microorganisms encounter when attempting to enter the body.
Which constitutes a major distinction between immune response and inflammatory response? In
contrast with the inflammatory response, the immune response: - Answers✔recognizes specific
invaders. Immune cells have the capacity to recognize a specific antigen, whereas inflammatory
cells respond in the same manner to any foreign antigen. Mounting an immune response
generally takes longer than inducing an inflammatory response.
A student nurse asks the clinician which cells are most primary in a patient's immunity. What is
the best answer? - Answers✔Lymphocytes. Lymphocytes (B and T cells) are responsible for
generating immune responses.
Humoral immunity is generated through the process of: - Answers✔producing antibodies.
Humoral immunity involves the production of antibodies that attack foreign antigens.
When a nurse uses the term "clonal diversity," what is the nurse describing? - Answers✔The
ability of the population of lymphocytes to recognize almost any antigenic molecule. The
generation of clonal diversity produces a population of lymphocytes that can recognize any
antigenic molecule.
When explaining "clonal selection" to a group of student nurses, which statement should the
nurse include? - Answers✔Lymphocytes that can recognize and react to a specific antigen
proliferate. The process of clonal selection occurs when an antigen selects those lymphocytes
with compatible receptors and expands their population. The immunocompetent B and T
lymphocytes also differentiate into mature B and T cells.
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: - Answers✔active acquired immunity. Active acquired immunity is obtained when an
individual is exposed to the antigen.
