Chapter 31 Asepsis

  1. - the freedom from
    disease-causing microorganisms. Clean vs. dirty
  2. state of infection and can
    take many forms, including septic shock.
  3. -localized swelling
    -localized redness, hyperemia (heat)
    -pain or tenderness
    -loss of function of body part
    signs of localized infection
  4. fever
    increase pulse, respiratory rate, if high fever
    malaise, loss of energy
    enlargement of lymph nodes
    signs of systemic infection
  5. normal wbc count is:
  6. nosocomial infection during diagnostic/ therapeutic procedures
    latrogenic infection
  7. antibodies are already present in the body, duration lifelong
    natural active immunity
  8. vaccination
    artificial active immunity
  9. host receives natural or artificial antibodies produced from another source
    passive immunity
  10. mothers immunity passed to baby through placenta
    natural passive immunity
  11. immunity after being exposed
    artificial passsive immunity
  12. chain of infection
    • etiologic agent (microorganism)
    • reservoir
    • portal of exit
    • method of transmission
    • portal of entry
    • susceptible host
  13. inhibits growth of some microorganisms
  14. destroy pathogens other than spores
  15. chemical used on skin
  16. toxic to tissue
  17. most inexpensive way to sterilize, but does not destroy all spores and virus
    boiling water for 15 minutes
  18. which type of precaution is used for C Diff?
    or contact
    contact precatuion
  19. order of putting on PPE
    • 1. gown
    • 2. mask
    • 3. eyewear
    • 4. gloves
  20. order of removing PPEs
    • 1. remove gloves
    • 2. eyewear
    • 3. gown
    • 4. mask
  21. Principles of surgical asepsis
    • 1. all objects used in a sterile field must be sterile
    • 2. objects become unsterile when touched by unsterile
    • 3. sterile items out of vision or below the waist or table level are considered unsterile
    • 4. sterile objects become unsterile by prolonged exposure to airborne microorganisms
    • 5. fluids flow in the direction of gravity
    • 6. skin cannot be sterilized and is unsterile
  22. exposure to bloodborn pathogens
    • 1. complete incident report
    • 2. get tested
    • 3.
  23. C diff requires what type of isolation:
  24. requires what type of isolation?
    droplet isolation
  25. tuberculosis requires what type of isolation?
    airborne isolation
  26. steps to bloodborne pathogen exposure
    • report incident immediately
    • complete injury report
    • seek evaluation: tesing of source of hepa B, C or hiv
    • for a puncture, encourage bleeding
  27. exposure to hiv requires
    treatment asap, preferably within hours of exposure
  28. droplet precaution
    if private room is unavailable, place client with the same infection in same room.

    place surgical mask on client during transport
