Pearson Chpt 7 NCLEX PN Preventing and Controlling Infection

  1. Comprised of:  etiologic agent, reservoir, portal of exit, method of transmission, portal of entry, susceptible host
    Chain of infection
  2. any pathogen capable of causing infection; causative agents include bacteria, virus, fungi, protozoa, ricettsiae, and helminths
    Etiologic agent
  3. faborable environment in which infectous organism grows and reproduces; it may be animate (human, animal, insect) or inanimate (food, water, soil, equipment); blood and respiratory, gastrointestinal (GI), reporductive, and urinary tracts serve as this in humans
  4. route by which microorganism leaves reservoir; it can be breaks in skin, the blood, and respiratory, GI, reproductieve, and urinary tracts in humans
    Portal of exit from reservoir
  5. mode by which microorganism is transferred from reservoir to host; transfer occurs by three mechanisms: direct and indirect
    Method of transmission
  6. involves physical transfer of causative agent from person to person; this inculdes touching, kissing, biting, and sexual intercourse. It can also ocur through droplets when a person talks, coughs, sneezes or spits within 3 feet of susceptible host
    direct contact
  7. involves transfer from reservoir to susceptible host via either a vehicle or a vector
    indirect contact
  8. this transmission require inanimate object to serve as a mode of transmission
    vehicle-borne transmission
  9. intermediary agent such as an animal or insect is required in this route of transmission
    vector-borne tranmission
  10. involves transport of droplet nuclei or dust bearing infectious agent by air currents
    airborne transmission
  11. these precautions represents first tier of CDC guidelines for isolation precautions
    Standard precautions
  12. what is the correct order for putting on PPE (personal protective equipment)
    gown, mask, eye protection and gloves
  13. what is the correct order for taking off PPE (personal protective equipment)
    gloves,mask, gown, and eye protection
  14. involves practices such as hand hygiene and use of PPE, to reduce the number and limit the spread of microorganisms
    Medical asepsis
  15. is also know as clean technique
    medical asepsis
  16. place specimen in a leak proof container with a biohazard label, then place contaienr in a sealed plastic bag
    lab specimen
  17. involves practices to maintain objects and areas free of microorganisms.  It is also know as steril technique
    Surgical asepsis
  18. involves the spread of infection through airborne droplet nuclei smaller than 5 microns, evaporated droplets that remain suspended in air for long periods of time, or dust particles containing infectious agents.  Example measles, chicken pox and TB
    Airborne precautions
  19. involves spread of infection by particle droplets larger than 5 microns that can be generated when clinet coughs, sneezes, talks, laughz, and so on.  Example diphtheria (pharyngeal), rubella, pertussis, mumps, pneumonia, and scarlet fever
    droplet precautions
  20. involves spread of infection by contact with client or contact with items in clients environment.  Example scabies, pediculosis, hermes simplex or zoster, hepatitis A, MRSA and VRE
    contact precautions
