Definitions Flashcards
Multidrug-resistant organisms (MDROs)
Organisms resistant to antibiotics; requires a harsher course of action
Normal flora
Microorganisms that live on skin, throat, GI tract, and on all other surfaces
Interferon
Nonspecific chemical inhibitor secreted by the body from a viral infection response
Granulocytes
Contains granules of digestive enzymes
Agranulocytes
Lack digestive enzymes
Antigens
Foreign particles
What are Antibodies?
Specific resistance to bacteria/viral infections
HAIs (healthcare associated infections)
MDROs produced from unsuccessful sterile techniques in the healthcare environment
Opportunistic organisms
Organisms in the right place at the right time, that do not usually cause infection.
Colonization
Organisms that grow and multiply on a surface without invading
Nosocomial infection
Hospital acquired infection
SIRS (systemic inflammatory response syndrome)
Earliest presenting symptoms of sepsis:
Fever
HR >90
RR > 20
PaCO2 < 32 mmHg
WBCs >12,000, <4,000
Sepsis
Severe systemic inflammatory response due to infection
Communicable period
Time period which disease is passed person-to-person
Communicable disease
Causative agent transmitted person-to-person
Leukocytosis
Rise in circulating WBCs above 5,000-10,000 cells/mm3
Shift to the left
Increase in # of immature cells
MIC (minimum inhibitory concentration)
Minimal amount of drug necessary to inhibit microbial growth in the lab
Superinfection
Secondary infection occurring when normal flora is destroyed
Incision
Type of acute intentional wound as part of a surgical treatment
Epidermis
Skins outer layer
Desquamation
Continuous shedding
