NR 283 PATHOPHYSIOLOGY EXAM QUESTIONS
AND CORRECT ANSWERS PROFESSOR-
VALIDATED.
Etiology - CorreCt Answer- Cause of a particular disease at the microscopic level
Cycle of Infection - CorreCt Answers - Pathogens, Reservoir, Portal of Exit, Mode of
Transmission, Portal of Entry, Host B
B-Cells - CorreCt Answers - Responsible for production of antibodies, can clone
themselves to tag antigens, can become memory B-cells to remember antigen(pathogen)
T-Cells - CorreCt Answers - Born in bone marrow, but mature in the thymus gland;
cell-mediated response
T-Killer Cells - CorreCt Answers - Phagocytosis of human cells that are infected
Helper T-Cells - Correct Answers- Like Nicolas Cage: "Fire! Fire! Fire!", directs adaptive
immune response in what to do
IgG - CorreCt Answers - Most common, in blood, Good God, there's a lot of them!
IgM - CorreCt Answers - first at the scene, IMMediate response
IgA - CorreCt Answers - spread from mother to child in colostrum in breast milk,
saliva, tears
IgE - CorreCt Answers - AllerGIES, allergic response, release of histamine
, IgD - CorreCt Answers - attached to B-cells; no one knows what they do
Active Immunity - CorreCt Answers - activates the immune system.
Active natural immunity - CorreCt Answers - natural exposure to antigen
Active artificial immunity - CorreCt Answers - immunizations
Passive natural immunity - CorreCt Answers - mother to fetus
Passive artificial immunity - CorreCt Answers - adult antibody injected into another
adult: Cystic fibrosis, PKU (phenylketonuria), Tay-Sachs
Cystic fibrosis - CorreCt Answer- autosomal recessive disorder that causes thick
mucous secretions
PKU (phenylketonuria) - CorreCt Answer- autosomal recessive disorder that causes
an inability to metabolize phenylalanine. Can cause intellectual disability. Pt must follow
a strict, very low-protein diet.
Tay-Sachs - CorreCt Answer- autosomal recessive disorder that causes an enzyme to
not be produced, causing fatty proteins to build up, destroying nerve cells in the brain
and spinal cord
Pathogenesis - CorreCt Answer - Story of how disease develops
Atrophy - CorreCt Answer- Decrease in the size of the cells, results in reduced tissue
mass
