Foundations

  1. review physical assessment findings and the patients medical conditions to determine the status of normal defense mechanism against infection
    status of defense mechanism
  2. aseptic technique refers to
    practices/procedures that help reduce the risk for infection
  3. define asepsis
    is the absence of pathogenic (disease producing) microorganisms
  4. systemic infections sometimes develop after the treatment of
    localized infection has failed
  5. ______ infections cause more generalized symptoms than local infections
    systemic
  6. some medications can increase susceptibility to infection true or false
    true
  7. 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
  8. __________ infections are a type of HAI from a diagnostic or therapeutic procedure
    iatrogenic
  9. granulation tissue is not as strong as tissue collagen and assumes  the form of
    scar tissue
  10. _____ may be serous (clear like plasma) sanguineous (containing rbcs), or purulent (containing wbcs and bacteria)
    exudate
  11. Normal wbc count
    5 to 10 thousand
  12. through the process of phagocytosis specialized wbcs called _____ and _____
    ingest and destroy microorganisms and other small particles?
    neutrophils and monocytes
  13. Phagocytosis is a process that involves
    the destruction and absorption of bacteria
  14. the cellular response of inflammation involves
    wbc arriving on site
  15. (Inflammation)rapid vasodilation occurs
    allowing more blood near the location of the injury
  16. 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
  17. 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.
  18. susceptibility to an infectious agent depends on the individuals degree of
    resistance to the pathogen
  19. infection cycle
    • 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
  20. 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.
