review physical assessment findings and the patients medical conditions to determine the status of normal defense mechanism against infection
status of defense mechanism
aseptic technique refers to
practices/procedures that help reduce the risk for infection
is the absence of pathogenic (disease producing) microorganisms
systemic infections sometimes develop after the treatment of
localized infection has failed
______ infections cause more generalized symptoms than local infections
some medications can increase susceptibility to infection true or false
Difference between exogenous and endogenous infections
- exogenous comes from microorganisms found outside the individuals. they do not exist as normal floras
- endogenous occurs when part of the patients flora becomes altered and an overgrowth occurs
__________ infections are a type of HAI from a diagnostic or therapeutic procedure
granulation tissue is not as strong as tissue collagen and assumes the form of
_____ may be serous (clear like plasma) sanguineous (containing rbcs), or purulent (containing wbcs and bacteria)
Normal wbc count
5 to 10 thousand
through the process of phagocytosis specialized wbcs called _____ and _____
ingest and destroy microorganisms and other small particles?
neutrophils and monocytes
Phagocytosis is a process that involves
the destruction and absorption of bacteria
the cellular response of inflammation involves
wbc arriving on site
(Inflammation)rapid vasodilation occurs
allowing more blood near the location of the injury
the inflammatory response includes the following:
- 1. vascular and cellular response
- 2. formation of inflammatory exudes( fluid and cells that are discharged from cells or blood vessels)
- 3. tissue repair
We are constantly exposed to billions of microorganisms every day why aren't we constantly sick?
Bc an infection does not develop until an individual becomes susceptible to the strength and numbers of the microorganisms.
susceptibility to an infectious agent depends on the individuals degree of
resistance to the pathogen
- an infectious agent or pathogen
- a reservoir or source for pathogen growth
- a port of exit for the reservoir
- a mode of transmission
- a port of entry to a host
- a susceptible host
What is the difference between infection and colonization?
- Colonization is the presence and growth of microorganisms within a host but w o tissue invasion or damage. disease or infection results only if pathogens multiply and alter normal tissue function
- infectious diseases have a low or no risk for transmission.
