PATHO FINAL EXAM 1 2022
LATEST EXAM
1. In a type II hypersensitivity reaction, when soluble antigens from infectious agents enter
circulation, tissue damage is a result of:
(correct answers)neutrophil granules and toxic oxygen products.
2. In which primary immune deficiency is there a partial to complete absence of T-cell immunity?
(correct answers)DiGeorge syndrome
3. Once they have penetrated the first line of defense, which microorganisms do natural killer (NK)
cells actively attack?
(correct answers)Viruses
4. Several bacteria, such as Mycobacterium tuberculosis, are resistant to killing by granulocytes
and can survive inside macrophages.
(correct answers)True
5. Stress has no effect on the development of cancer.
(correct answers)False
6. How are the functions of major histocompatibility molecules and CD1 molecules alike?
(correct answers)They are both antigen-presenting molecules (APCs).
7. Each individual T and B lymphocyte specifically recognizes only one particular antigen.
(correct answers)True
8. A person does not have a stress reaction unless the stress exceeds his or her coping abilities.
(correct answers)True
9. The class of antibody involved in type I hypersensitivity reactions is:
(correct answers)IgE.
10. A major immunologic finding in AIDS is the striking decrease in the number of which cells?
(correct answers)CD4+ Th cells
11. The helper T cell (Th) interacts with immunocompetent B cells causing the production of plasma
cells.
(correct answers)True
12. Which class of immunoglobulins forms isohemagglutinins?
(correct answers)IgM
13. Which statement is true about the differences between stress-induced hormonal alterations of
men and women?
(correct answers)Androgens appear to reduce a greater degree of immune cell apoptosis
following injury, creating greater immunosuppression in injured men than women.
14. The effect epinephrine has on the immune system during stress response is to increase:
(correct answers)NK cells.
