urine scolding is common along with this
prevented through moving pt
decubital ulcer aka
3 things that can be done to eliminate or control a source of dz
what factors effect a pts susceptibility to dz?
- therapeutic agents
3 things that should be done to prevent transmission of microbes
- wash hands
- physical control
- chemical control
3 physical control methods?
the use of a filter to separate particulate matter from liquids or gases
commonly used on pharmaceuticals
this is primarily used during production and packaging of certain sx products like gloves and suture material
what are the 3 types of radiation?
this type of radiation has a drying effect that causes mutations of nucleic acid in MOs
used on surfaces and air
type of radiation that is rapid and continuous
this radiation is used to prepackage suture, gloves, and rubber tubing
the most common method of sterilization
what are the 2 types of heat?
this type of heat sterilization is done by either boiling or steam under pressure
kills microbes by coagulating critical cellular proteins
type of heat sterilization that is difficult to control
longer sterilization pd, kills microbes by protein oxidation
type of moist heat
only sanitizes at 60C or 140F & higher
sanitizin can be increased with scrubbing and detergent
ex: auto dishwashers/ clothes washers
type of moist heat (2)
rarely used because spores and viruses are not killed @ this temp for long pds of time
max temp 212F 100C
- free flowing steam
what method of sterilizing do autoclaves use?
steam under pressure
kills all forms of microbial life including spores and cyts
an autoclave is run for ___ mins, at ____ temp and ____ psi
why is tap water not used with the autoclave?
tap water has minerals that will deposit and clog over time
ideally we should use ____ water in the autoclave
the autoclave (at school) automatically opens when the temp reaches ___, but it should sit b.c of ____
what is the procedure for flash sterilization?
3-4 mins unwrapped @ 270-272F 15psi
what 3 things allow for proper sterilization in the autoclave?
- operation of autoC
- pack prep
- chamber loading
drying uses _____ free from _____
drying kills MOs through ____
what is the one major benefit of dry heat?
doesnt corrode/dull instruments/needles
what is important to remember about using dry heat and the evaporation process?
- this basically aersolizes whatever was on those tools.
- this will increase dispersal of MOs
this method of dry sterilization gives complete destruction of materials that are non-reusable and have no value
ex: paper drapes
w/ incineration, the material must b completely reduced to ash because if there are clumps ____ may still be present/protected
a hot air oven needs a temp of ____-____C or ____F for ____ hours.
this method of dry sterilization doesnt dull/corrode metals/sharps
takes longer/requires higher temp
paper, cloth, plastic and rubber should not be sterilized this way
hot air ovens
