Infection (NUR 120) Questions with
100% Correct Answers
infection Correct Answer: the establishment of a pathogen in a susceptible host
that causes damage
pathogen Correct Answer: microorganism that can cause damage
normal flora Correct Answer: - non-disease-causing microorganisms that grow &
live in or on the body (good bacteria)
- 1st line of defense
- ex. bacteria, fungi, viruses & parasites
inflammatory (non-specific) response Correct Answer: - 2nd line of defense
- produces pain, warmth, redness, swelling & fever, chills, malaise & altered
mental status (if becomes systemic)
inflammation Correct Answer: body's initial response to tissue damage or
infection that includes capillary dilation & leukocyte filtration
immune response Correct Answer: - 3rd line of defense
- the body's attempt to protect itself from foreign & harmful substances
- initiated by the recognition of antigens
antigen Correct Answer: any substance that provokes an adaptive immune
response
, innate (non-specific) immunity Correct Answer: provides immediate defense
against foreign antigens by producing chemical medications that fight
infection, remove foreign substances & activate adaptive immune system
passive immunity Correct Answer: - when a person receives an antibody
produced in another body
- provides immediate but short-term protection against antigens
- ex. mother to infant through breastfeeding & immunoglobulins through IVs
from donor
adaptive (specific) immunity Correct Answer: antigen-specific immunity that
provides long term immunity when the body is exposed to a microorganism
(makes antibodies)
humoral immunity Correct Answer: type of adaptive immunity that involves
WBC's that produce antibodies in response to antigens or pathogens circulating
in lymph & blood
cell-mediated immunity Correct Answer: type of adaptive immunity where
specific WBC's fight microorganisms & attack anything that they identify as non-
self (foreign)
hypersensitivity Correct Answer: - an exaggerated response by the immune
system to a particular substance
- ex. allergies
- autoimmune disorders (when your immune system identifies cells in your own
body as foreign & attacks them)
- impaired immune response (decreases the ability of the immune system to
respond to infection --> ex. AIDS & immunocompromised pts)
