NURS 399 IMMUNITY EXAM QUESTIONS WITH
ANSWERS 100% CORRECT
immunity - ANSWER resistance to disease
Pluripotent to specialized cells - ANSWER E.g. Erythropoietin is a growth factor for
RBCs.
Human Leukocyte Antigen (HLA) - ANSWER unique surface proteins of a cell specific to
an individual
Why are HLA's important? - ANSWER They are capable of triggering an immune
response
Needed components of an optimal immune system - ANSWER -Interaction of immunity
and inflammation working together
-Nonspecific defenses
-Functional lymphatic system
-Efficient innate immune system
-Operational inflammatory response
-Appropriate adaptive immune response
-Microbiome
Microbiome - ANSWER all of the microorganisms that live in a particular environment,
such as a human body (non-pathogenic)
innate immunity - ANSWER Immunity that is present before exposure and effective from
birth. Responds to a broad range of pathogens.
*** Frontline soldiers
, What cells make up innate immunity? - ANSWER - Epithelial skin barriers
-GI and Respiratory tract
-Phagocytic leukocytes (neutrophils and macrophages)
-Natural killer cells (NK)
- Several circulating plasma proteins
adaptive immunity - ANSWER Acquired and can take up to 7-10 days to provide
protection but is specific to the antigen
***sniper
What cells make up the adaptive immunity? - ANSWER Lymphocytes and their products
What are the two types of adaptive immunity? - ANSWER humoral and cell mediated
humoral immunity - ANSWER Mediated by souluble proteins called antibodies produced
by B lymphocytes (B cells)
cell-mediated immunity - ANSWER Involving T lymphocytes (T cells)
innate immunity process - ANSWER 1. Inflammatory responses triggered by histamine
2.Vasoconstriction of nearby arterioles to limit blood loss
3. Vasodilation to dilute toxins and provide essential nutrients, immune cells, and
oxygen
4.Leukocytes line the capillary walls and prepare to migrate into tissues where they will
begin clearing up foreign substances and cell debris
5. WBCs start replacing lost tissue/repair damaged tissue by inducing healthy cells to
divide
6. Fibrinogen converted to fibrin and confines foreign substances to small area
