packaging used for gas plasma - ANSWER ✓ must be able to tolerate deep
vacuum draw, with out absorbing the sterilant.
rigid container system - ANSWER ✓ instrument containers that hold medical
devices during sterilization and also protect devices from contamination during
storage and transport
wet-pack - ANSWER ✓ containers with moisture, after the sterilization process is
completed.
kraft-type papers - ANSWER ✓ a medical grade paper packaging material used
for numerous sterilization applications.
SMS spunbond-meltblown-spunbond - ANSWER ✓ non woven packaging
material which is the most popular flat wrap.
papers/pouches that contain cellulose; - ANSWER ✓ cannot be used in gas plasma
sterilizers because cellulose absorbs the sterilant and reduces penetration of
sterilant.
paper plastic pouches/SMS wraps - ANSWER ✓ acceptable for use with steam
and EtO sterilization processes.
, spunbond polyolefin-plastic/SMS wraps - ANSWER ✓ used for gas plasma
sterilization. Referred to as tyvek pouches, contains no cellulosic materials
therefore compatible with gasplasma/Hydrogen peroxide.
basin sets should not exceed - ANSWER ✓ 7 lbs
wicking material - ANSWER ✓ an approved absorbent material that allows for air
removal, steam penetration and facilitates drying.
package labeling should include - ANSWER ✓ description of contents.
initials of assembler.
lot control number.
sterilizer ID and cycle.
Date/Time.
packaging materials should be held; - ANSWER ✓ at room temperature 64°F-
72°F, humidity ranging from 35% - 70% for a minimum of two hours before
sterilization.
wrapped pans of instruments should not exceed. - ANSWER ✓ 16 lbs
containerized instrument sets should not exceed - ANSWER ✓ 25 lbs
sterility time related - ANSWER ✓ specific expiration date is reaached
sterility event related - ANSWER ✓ considered sterile unless the integrity of the
packaging is compromised or suspected of being compromised by an event
regardless of expiration date.
FIFO - ANSWER ✓ first in first out.
point of use processing - ANSWER ✓ occurs when a medical device is processed
immediately before use, and/or close to the patient care area
flash sterilization / IUSS - ANSWER ✓ process by which unwrapped instruments
are sterilized for immediate use when an emergency situation arises.
, 3 agencies that have established standards, guidelines, and recommendations for
IUSS - ANSWER ✓ AAMI.
AORN.
Joint commission.
Flash/IUSS cycles - ANSWER ✓ gravity.
pre-vacuum.
express.
commun IUSS exposure times - ANSWER ✓ 3.

IUSS gravity cycle.
single instrument comprised of metal and without lumens. - ANSWER ✓ 3
minutes @ 270°F
IUSS gravity cycle.
complex or lumened instruments, mixed load - ANSWER ✓ 10 minutes @ 270°F
preset express cycle - ANSWER ✓ 4 minutes @ 270°F with 3 minutes drying
time, total cycle time of 12 minutes.
pre-vacuum load of mixed materials, or items with lumens - ANSWER ✓ 4
minutes @ 270°F
to properly decontaminate dirty instruments, they must be opened and
disassembled to the smallest part - ANSWER ✓ then soil and debris can be washed
away from the jaws, box locks, crevices, and other challenging areas.
if trays are used for flash sterilization, they should be - ANSWER ✓ perforated or
mesh-bottomed to ensure good circulation of the steam in the sterilizers chamber.
if rigid containers are used they should be specifically designed for flash
sterilization.
pre cleaning is the most important part of the decontamination process -
ANSWER ✓ up to 99% of microorganisms on an instrument can be removed with
thorough cleaning.
, class 5 integrators - ANSWER ✓ integrating indicators designed to react to all
critical parameters over a specified range of sterilization cycles. they are correlated
to the biological kill of Geobacillus stearothermophilus, used to monitor steam
sterilization cycle efficacy.
biological indicator - ANSWER ✓ sterilization process monitoring device
consisting of a standardized viable population of microorganisms "spores" known
to be resistant to the mode of sterilization being monitored
incubation temperature for geobacillus stearothermophilus is - ANSWER ✓ 122°F
- 140°F
Control BI - ANSWER ✓ unsterilized or processed BI that is incubated to confirm
spores in a batch of BI's are viable. Control BI's should always be positive.
residual air removal test - bowie dick test
Class 2 - ANSWER ✓ test for sterilizers with a pre vacuum cycle, checks the
efficiency of the sterilizers air removal system during the pre vacuum cycle to
detect inadequate air removal or air leaks in the chamber.
steam pressure on the chamber and jacket gauges must be equal during the
exposure phase of the cycle both should be at least: - ANSWER ✓ 27psi @ 270°F.
31psi @ 275°F
documentation for each flash cycle should include - ANSWER ✓ patients name.
contents.
cycle used.
reason.
signature of staff person responsible.
critical devices - ANSWER ✓ introduced directly into the bloodstream or other
normally sterile areas of the body.
should undergo a sterilization process.
semi-critical devices - ANSWER ✓ come in contact with non-intact skin or
mucous membranes where risk of infection is less.
should receive a minimum of high-level disinfection
