Principles and Practice of surgical technology
Show Answers:

  1. What is Asepsis?
    Absence of pathogenic microorganisms
  2. What is Aseptic principles?
    Principles applied though use of sterile techniques to prevent microbial contamination of the surgical environment.
  3. What is Bactericidal?
    Substance that destroys/kills bacteria
  4. What is Bacteriostatic?
    Substance that inhibits the growth and reproduction of bacteria.
  5. What is Bioburden?
    The number of microbes or amount of organic debris on an object at any given time.
  6. What is contamination?
    The presence of pathogenic materials.
  7. What is Cross-contamination?
    The contamination of a person or object by another.
  8. What is Decontamination?
    To reduce to an irreducible Minimim the presence of pathogenic material.
  9. Define disinfection.
    • Process in which most but not all the microorganisms located on inanimate surfaces are destroyed.
    • (decontamination is a category of disinfection.)
  10. Define antisepsis.
    Process in which most but not all microorganisms located on animate surfaces, such as the skin are destroyed.
  11. What is Antiseptic?
    Name used to describe the solutions that are used by the sterile surgical team member to perform the surgical scrub and are used on the patient for skin preparation of the surgical site.
  12. What is Sterilization?
    Destruction of all microorganisms, including spores on inanimate surfaces. Anything used in the surgical procedure needs to be sterile.
  13. Define Disinfectant.
    Chemical agent that kills most microbes, but usually not spores, usually used on inanimate objects because these compounds are too strong to be used on living tissues.
  14. Define Event-releted sterility.
    Sterility determined by how a package is handled rather that time elapsed; a package is considered sterile until opened or the integrity of packaging material is damaged.
  15. Define Fomite.
    Inanimate object that harbors microorganisms.
  16. Define Fungicide.
    Agent that destroys fungus.
  17. Define Infection.
    Invasion of the human body or tissue by pathogenic microorganisms that reproduce and multiply, causing disease.
  18. Define Nosocomial.
    Infection acquired within a health care facility
  19. Define pathogen.
    Any microbe capable of causing disease
  20. Define Resident flora.
    Microbes that normally reside below the skin surface or within the body.
  21. Define Sepsis.
    Infection, usually accompanied by fever, that results from the presence of pathogenic microorganisms.
  22. Define Spore.
    A resistant form of certain types of bacteria that are able to survive in adverse conditions.
  23. Define Sporicide.
    Substance that kills/destroys bacteria in the spore stage.
  24. Define sterile.
    Having been rendered free of all living microorganisms, including spores.
  25. Define Sterile technique.
    Techniques of creating a sterile field and performing within the sterile field to keep microbes at an irreducible minimum
  26. Define Strike-through contamination.
    Contamination of a sterile field that occurs through the passage of fluid through, or a puncture in, a microbial barrier.
  27. Define Surgically clean.
    Mechanically cleaned and chemically disinfected but not sterile.
  28. Define Terminal disinfection.
    To render items safe to handle by high-level disinfection
  29. Define Terminal sterilization.
    To render items safe to handle by sterilization
  30. Define Transient flora.
    Microbes that reside on the skin surface and are easily removed.
  31. Define Vector.
    Living Carrier that transmits disease.
  32. Define Virucide.
    Agent that destroys viruses.
  33. What are the 3 classification of patient care items?
    • Critical
    • (Invasive procedures)

    • Semi-Critical
    • (non-intact skin)

    • Non-Critical 
    • (intact skin)
  34. What are the 3 levels of disinfection?
    • Cleaning, physical removal of bioburden
    • Disinfection, 3 levels
    • Sterilization
  35. What are the factors influencing the efficiency of disinfectants?
    • - concentration level of the disinfectant solution
    • - bioburden
    • - contact time 
    • - physucak factors of the solution, including temperate of the solution, water hardness and pH level, and exposure time
  36. Who is cleaning accomplished?
    use of a detergent mixed with water and mechanical action.
  37. What does MSDS stand for?
    Material Safety Data Sheet
  38. What are 2 High-leverl disinfectant compounds?
    • Glutaraldehyde 
    • (Cidex)

    • Sodium Hypochlorite
    • (Household bleach)
  39. List most common Intermediate-Level disinfectant compounds.
    • Phenol
    • (carbolic acid)

    • Quaternary Ammonium Compounds
    • (quats)

  40. What needs to be done for the first surgical procedure?
    OR furniture, equipment, surfaces, and lights must be "damp-dusted"
  41. Decontamination practices in the OR intraoperative decontamination comes secondary to paying c lose attention to the surgical procedure and working with the surgeon one-on-one.

    T or F
  42. Who is responsible for the "turn over" of the OR in-between each procedure?
    Surg-Tech and environmental services personnel.
  43. What does CSPD stand for?
    central sterile processing department
  44. The elevator used to transport the cart to the CSPD is called what?
  45. Who is responsible for loading the cart after the surgical procedure is down?
    Surgical technologist
  46. Transferring the car to the CSPD, decontamination process, storing the instruments. And pulling a surgeon's preference card for a particular procedure and placing it on the clean and sterile cart is the responsibility of whom?
    CSPD personnel
  47. What is a Bowie-Dick test?
    The test is used in the pre vacuum sterilization cycle to check for air removal and entrapment and its conducted daily. The test is performed at the first run of the day before any loads are sterilized or after the sterilizer bad undergone repairs.
