True. It is binary
True or False: If you touch a sterile object with gloves you got from this box, it is no longer sterile.
True. If something is sterile and it has been touched by a contaminated object, it is no longer sterile. Those gloves are not sterile.
True or False: The only way for a sterile object to become no longer sterile is if a contaminated object touches it.
False: Anything that has become unintentionally wet or damp is not longer sterile
term. Surgical Asepsis
def. the COMPLETE removal of ALL microorganisms and their spores
True or False: There are degrees of sterility
False: An item is either sterile or it is not
When is surgical asepsis necessary?
For any procedure that penetrates the skin, including catheterization
term. sterile field
def. an area that has been prepared to receive the sterile equipment and instruments
What is the best thing to do if you are observing in a sterile field?
Keep your hands to yourself
Location where sterilization of equipment happens in hopsitals?
Central Supply aka Central Service Department

Sterile = Steam under pressure aka Autoclave
Dry heat
Gloves = Gas
ETOX + CO2
Gas Plasma
Required In= Radiation, Ionizing
Cobalt 60
Cesium 137
Clean = Chemicals
Bedrooms = Boiling
What sterilization method(s) is/are the quickest?
Steam under pressure (Autoclave)
What sterilization method(s) is/are the most convenient?
Steam under pressure (Autoclave)
What sterilization method(s) is/are the most commonly used?
Steam under pressure (Autoclave)
Gas
What sterilization method(s) is/ are used for items that cannot tolerate heat or moisture?
Gas
What sterilization technique takes longer?
a. steam under pressure (autoclave)
b. gas
c. both take equally as long
g. gas
What sterilization method(s) is/ are used for sterilizing blood products?
ionizing radiation
What sterilization method(s) is/ are used for sterilizing food products for immunocompromised patients?
ionizing radiation
What sterilization method(s) is/ are the oldest?
Boiling
What sterilization method(s) is/ are better suited for disinfecting rather than sterilzing?
Chemicals
boiling
What is dry heat sterilization method used for?
needles
items sensitive to moisture
Why is dry heat not used very much
It takes a lot longer
most items it is useful for are now disposable
What is incineration used for?
destruction of hazardous waste NOT sterilization
What type of gasses are used?
ETOX (ethylene oxide) + CO2
Gas plasma
What is gas plasma?
a more recent alternative
gas in a highly charged vacuum state, the gas creates free radicals that destroy microbes
True or False: Ionizing Radiation is commonly used in hospitals to sterilize equipment.
False
What is Ionizing Radiation used for?
Sterilizing blood produces
food sterilization for immunocompromised patients
What isotopes are used to for sterilization techniques with ionizing radiation?
Cobalt 60
Cesium 137
True or False: Though not commonly used in hospital equipment, chemicals are great at sterilizing.
False: they are better for disinfecting
Why are chemicals not as good for sterilizing?
Chemicals can become easily contaminated & most don’t truly sanitize
At what temperature must you boil an item to sterilize it?
212 F (100C)
For how long must an object be boiled to sterilize it?
30 min
Why is boiling not as good for sterilzing?
It does not destroy all the spores
