Phleb. Chapt. 4

  1. chain of infection:
    continuous link among the infection source, the means of transmission and the susceptible host

    *infectious agent--reservoir--portal of exit from reservior--method of transmission--portal of entry to host--susceptible host--
  2. airborne infection isolation precautions:
    precautions used with patients known/suspected to have serious illnesses--airborne droplet nuclei
  3. airborne transmission:
    spread of infection either by ariborne droplet nuclei or by dust particles that contain microorganisms
  4. bloodborne pathogens (BBPs):
    infectious agents carried in the blood
  5. common vehicle transmission:
    transmission by means of contaminated items: food, water, meds, devices and equipment
  6. contact precautions:
    used for patients known/suspected to have serious illnesses easliy transmitted by contact or contact with patient environment
  7. contact transmission:
    transfer of microorganisms from an infected person to susceptible host by body surface-to-body surface contact or through contact with contaminated objects
  8. droplet nuclei:
    particals smaller than 5um that remain suspended in air for long periods of time
  9. droplet precautions:
    used for patients known/suspected to have serious illnesses transmitted by large partical droplets
  10. droplet transmission:
    spread of infection through airborne droplets
  11. expanded precautions (EPs):
    targeted at patients known/suspected to be infected with a highly transmissible pathogen
  12. exposure control plan:
    comprehensive document outlining all procedures and policies for preventing the spread of infection
  13. fomite:
    contaminated object
  14. healthcare associated infections:
    infections contracted by a patient during a hospital stay
  15. high-efficiency particulate air (HEPA):
    type of air filter
  16. infection:
    invasion by and growth of a microorganism in the human body that causes disease
  17. isolation:
    seperation of an infection source from susceptible hosts, thereby breaking the chain of infection
  18. nosocomial infection:
    infection acquired during a hospital stay (same as healthcare ass. infections)
  19. pathogens:
    a bacterium, virus, or other microorganism that can cause disease
  20. personal protective equipment (PPE):
    fuild resistant gowns, masks, repirators, face shields, shoe covers and gloves
  21. protective equipment (PE):
    isolation of immunocompromised patients to prevent exposing them to infection
  22. reservoir:
    person carrying an infectious agent without being sick
  23. sepsis:
    bacterial infection
  24. standard precautions
    infection control method that uses barrier protection and work control practices to prevent direct skin contact with blood, body fluids and tissues from all persons
  25. vectors:
    carriers of disease (ex: fleas, ticks, mosquitoes, etc.)
  26. BBPs:
    bloodborne pathogens
  27. CDC:
    centers for disease control and prevention
  28. EPs:
    expanded precautions
  29. HEPA:
    high-efficiency particulate air
  30. MRSA:
    methicillin-resistant staphylococcus aureus
  31. NIOSH:
    National Institute for Occupational Safety and Health
  32. OSHA:
    Occupational Safety and Health Administration
  33. PE:
    protective equipment
  34. PPE:
    personal protective equipment
  35. SARS:
    severe acute respiratory syndrome
  36. VRE:
    vancomycin-resistant enterococcus
  37. what is a vector?
    infectious agents carried by arthropods. symbiosis

    ex- ticks, fleas, flies, mosquitoes, bugs
  38. what is a common vehicle?
    fomites (contaminated objects)

    ex- food, water, pills, equipment, computer keyboard, door knobs, pens/pencils, stethoscopes, etc.
  39. droplet
    sneezing, wheezing, coughing, spitting

    travels 3ft and lands on mucous membranes. PPE. shares same airflow.
  40. airborne
    sneezing, etc. + dust particles

    travels on air currents--inhaled. PPE + expanded precaution= HEPA filter, N95 mask and negative airflow isolation room. Seperate airflow. Ex- TB
  41. OPIM
    other potentionally infectious material
  42. microbiology
    • 1. virology - viruses
    • 2. bacteriology - bacteria
    • 3. mycology - fungi
    • 4. parasitology - parasites, protists
  43. if you're on antibiotics you should take/eat a...
