NR 605 Exam 1 Question With
Verified Answers
incidence rate - correct answer-the number of new cases of a disease (in a specific
period: usually a year)
divided by
the number of individuals in a population
prevalence rate - correct answer-proportion of the population affected by a disease in a
given time
-remember if we are good at treating a chronic disease, the prevalence may be higher
cell injury causes - correct answer-Depletion of ATP
decreased oxygen in the cell - correct answer-increased release of free radicals
increased free radicals leads to - correct answer-increased intracellular calcium
increased cell calcium leads to - correct answer-defects in cellular membrane
defects in cell membrane lead to - correct answer-cell death
ABO antigens - correct answer-Individual receives either A antigen, B antigen or neither
(O)
A antigen has - correct answer-B antibodies
B antigen has - correct answer-A antibodies
AB antigen has - correct answer-no antibodies
O antigen - correct answer-A and B antibodies
Universal donor - correct answer-O
Universal recipient - correct answer-AB
immunoglobulins - correct answer-IgG
IgM,
IgA
IgE
, IgD
IgG - correct answer-most abundant antibody
active agains viruses, bacteria and toxins
IgM - correct answer-Largest, 1st antibody produced in response to an antigen
Timing of IgG and IgM - correct answer-refer to photo
IgA - correct answer-found in secretions and mucous membranes
IgE - correct answer-active in allergies and parasitic reactions
Causes release of histamine
IgD - correct answer-activation of B and T cells
Type I Hypersensitivity - correct answer-IgE mediated
Allergic reactions
with exposure to antigen IgE bind with mast cells causing the release of histamine
bronchial constriction, urticaria, increased mucous, edema (capillary perm), increased
blood flow (vasodilation)
allergic reactions, bee sting, shellfish, anaphylaxis
Type II hypersensitivity - correct answer-IgG mediated
IgG binds to cell antigen leading to destruction of the cell
ABO reactions, hemolytic disease of the newborn
Type III Hypersensitivity - correct answer-antigen binds with IgG and IgM to form a
complex
Arthus reaction
SLE, rheumatoid arthritis, autoimmune
Arthus reaction - correct answer-Complexes of IgG, IgM and antibody become trapped
in small vessels leading to inflammation
Type IV Hypersensitivity - correct answer-Cell-mediated, delayed hypersensitivity
