    chlorine
  4. what halogen is intermediate level and includes water, sewage, wastewater, and inanimate objects
    chlorine
  5. what halogens are iodophors the interfere with disulfide bonds of proteins
    iodine
  6. what halogen is intermediate level include milder medical and dental degermine agaents, disinfectants, and ointements
    iodine
  7. what germicidal category disrupt cell walls and membranes and precipitate proteins
    phenolics
  8. what germicidal category is low to intermediate level include bactericidal, fungicidal, virucidal, not sporicidal
    phenolics
  9. what germicidal category includes lysol and triclosan-antibacterial additive to soaps
    phenolics
  10. what germicidal category is a surfactant and protein denaturant with broad microbicidal properties
    chlorhexidine
  11. what germicidal category are low to intermediate levels, include hibiclens and hibitane
    chlorhexidine
  12. what germicidal category are used as skin degeming agents for preoperative scrubs, skin cleaning, and burns
    chlorhexidine
  13. what germicidal category acts as surfactants dissolving membrane lipids and coagulating proteins of vegetative bacterial cells and fungi
    alcohols
  14. what germicidal category are intermediate level include, ethyl and isopropyl in solutions of 50-95%
    alcohols
  15. what germicidal category gram-alcohols=drinking and isopropanol=rubbing alcoho; primary not pure 70%alcohol and 30% water= best
    alcohols
  16. what germicidal category produce highly reactive hydroxyl-free radicals that damage protein and DNA while also decomposing to O2 gas- toxic to anaerobes
    hydrogen peroxide
  17. what germicidal category antiseptic at low concentrations; strong solutions are sporicidal
    hydrogen peroxide
  18. what germicidal category can be toxic to anerobic bacteria 3%=use on skin 30%=eat skin away OH- very reactive
    hydrogen peroxide
  19. what germicidal category kill by alkylating proteins and DNA (alkylating=aldehyde reacts with certain molecules to change structure)
    aldehydes
  20. what aldehydes is in 2% solution (cidex) used as sterilant for heat sensitive instruments HIGH LEVEL
    gluteraldehye

    formaldehyde
  22. what germicidal category are strong alkylating agents, chemicals are explosive hense why contained in chambers
    gases and aerosols
  23. what germicidal category are high level and include ethylene oxide and propylene oxide
    gases and aersolos
  24. what germicidal category sterilize and disinfect plastics and prepackaged devices, food
    gases and aerosols
  25. what germicidal category has quaternary ammonia compounds that act as surfactants that alter membrane permeability of some bacteria and fungi
    detergents and soaps
  26. what germicidal category are very low level and molecule is amphipathic which can disrupt membrane
    detergents and soaps
  27. what germicidal category mechanically remove soil and grease containing microbes
    soaps
  28. what germicidal category are solutions of silver and mercury kill vegetative cells in low concentrations by inactivating proteins
    heavy metals
  29. what germicidal category are low level include merthiolate, silver nitrate, silver
    heavy metals
  30. what germicidal category have oligodynamic action (small concentration of + ions on living things) can be toxics, some microorganisms can develope resistance
    heavy metals
  31. what germicidal category are very active against gram-positive species of bacteria and various fungi
    dyes as antimicrobial agents
  32. what germicidal category are low level, narrow spectrum of activity; sometimes used for antisepsis and wound treatment
