Decontamination Area Soiled equipment is received, disassembled to their smallest components, and
decontaminated.
Assembly Area Inspected, tested, reassembled, packaged.
Storage & Distribution Sterilized item storage prior to transportation.
What pressure is the decontamination area under? Negative, to contain contaminants.
Which area are items inspected and identified for repair? Assembly area.
At what point can sterilized items become contaminated? Any time during handling, transport, or storage.
What are the two types of organizational structures? Vertical (upper management down) and Team-Based (more of an open structure
with communal input).
Policies and procedures in the MDRD are guided by what CSA and the PIDAC (Ministry of Ontario Best Practices) document.
two governing bodies?
What does PIDAC stand for? Provincial Infectious Diseases Advisory Committee.
6 external quality control bodies? CSA, Accreditation Canada, and PIDAC, Association for the Advancement of
Medical Instrumentation (AAMI), and two bodies about Operating Room Nurses.
Who is the regulatory body for Workplace Hazardous WSIB (Workplace Safety Insurance Board)
Materials Information Systems (WHMIS)?
Study WHMIS pictograms. OK.
Do all Hazard Classes and Categories require a No
Pictogram from WHMIS?
How often do Safety Data Sheet (MSDS and SDS) need
to be updated? Not every 3 years.
Where should SOPs be kept? In a central location. Electronic and physical.
What does QMS stand for? Quality management systems.
Suffix Means "after"
Microorganisms: Unicellular, most aren't harmful.
Spore Coat Bacterial cells will produce a spore coat to resist heat, drying, and chemicals.
, Characteristics of Proteins Insoluble in water, will coagulate with heat, drying, and specific chemicals.
Coagulated proteins can trap pathogens. This is why the removal of protein
before disinfection or sterilization is the prime objective of cleaning in MDRD.
Three types of bacteria: Aerobic, anaerobic, and facultative anaerobe.
What are bacteria? Single-celled organisms, less than 1% cause disease.
Two types of bacterial cell walls: Thicker (gram positive), and thinner (gram negative). The "gram" term comes from
the gram stain test to determine successful sterilization.
What are viruses? Smaller than bacteria, non-living. Parasitic and uses other cells to reproduce.
What are fungi? Mold, yeast.
What are MDRO? Multiple drug resistant organisms.
What are prions? Infectious organic proteins. Can remain infectious for years in a dried state, resists
routine sterilization and disinfection.
What are the components of bacterial microorganisms? Nucleic material, cytoplasm, membrane, cell wall, flagella, fimbriae.
How prevalent are HAIs? Healthcare associated infections are the 4th leading cause of death.
What are the 5 modes of infection transmission? Contact (direct or indirect) - Droplet - Airborne - Vehicle - Vector
What is the single most important way to break the chain Cleaning your hands.
of infection?
Direct contact: Physical contact.
Indirect contact: Sneezing, coughing, fomites. A dirty scope is a fomite.
What are 5 routine practices that could prevent infection? Hand hygiene, PPE, administrative controls, risk assessment, and environmental
controls.
What is the most common mode of transmission in the Indirect contact.
MDRD?
How often should the MDRD be cleaned? Counters and floors daily. Walls every 6 months.
Spaulding's Classifications: Non-critical: touches intact skin (cleaning then low-level disinfection or mid-level).
Semi-critical: touches mucous membranes (cleaning then HLD or sterilization).
Critical: enters a sterile space, vascular system, or body space. Cleaning then
sterilization.
What devices are recommended to be single-use Needles, tubing and suction tips, glassware.
