Patho 1 SPA questions
Which of the following statements is FALSE regarding the immune system: - The immune response displays memory which can allow a faster and stronger future response - Acquired active immunity is not produced by the individual's immune response - B cells are part of the humoral immune response - The immune response displays specificity, and recognizes a specific antigen
Acquired active immunity is not produced by the individual's immune response
Clinical manifestations of inflammation include all of the following EXCEPT: - Redness - Warmth - Swelling - Pain - All of the above are correct characteristics
All of the above are correct characteristics
All of the following occur during the acute inflammatory response EXCEPT: - Capillary vasoconstriction. - Mast cell degranulation releases biochemical mediators in the vasculature - Increased capillary permeability - Exudate and edema is formed.
Capillary vasoconstriction
One systemic manifestation of the acute inflammatory response is fever which is produced by: - Endogenous pyrogens acting directly on the hypothalamus - Direct action of a bacterial endotoxin on the hypothalamus - Antigen-antibody complexes acting directly on the cerebellum - The combination of bacterial endotoxins and antigen-antibody complexes acting directly on the hypothalamus
Endogenous pyrogens acting directly on the hypothalamus
The best definition of phagocytosis is: - Ingestion of bacteria, dead cells, and debris to facilitate death and removal - Mast cell degranulation - The facilitation of rapid vasodilation of capillaries - A cellular process controlled by biochemical mediators
Ingestion of bacteria, dead cells, and debris to facilitate death and removal
Select the best choice to support the statement that the blood group O is called the "universal donor" because: - It carries Rh+ antigens - It carries neither A nor B antigens - It carries both A and B antigens - It carries both anti-A and anti-B antibodies
It carries neither A and B antigens
Suppressor T cells are responsible for: - Direct killing of the antigen - Facilitation of other T cells and B cells to respond - Memory cell production - Regulating the strength of the response
Regulating the strength of the response
Why are the elderly at higher risk for infections? - The humoral line is immunocompromised. - The cell numbers decline as people age. - The cell numbers are about normal, but the function of the cells is not as good. - At about eighty years after birth, the maternal antibodies are finally gone.
The cell numbers are about normal but the function of the cells is not as good
Why is the AB blood group called the universal recipient? - The cells contain both anti-A and anti-B antibodies. - The cells contain both A and B antigens. - The cells contain Rh+ antigens - The cells contain antibodies to type O blood.
The cells contain both A and B antigens
Which of the following statements is FALSE? - The inflammatory response occurs much faster than the immune response - The immune response can be induced by vaccination - The inflammatory response involves several different plasma systems - The inflammatory response involves immunoglobulin (antibody)
The inflammatory response involves immunoglobulin (antibody)`
