MDRAO Exam Prep – Questions With Verified
Solutions
Decontamination Area Correct Answer - Soiled equipment is
received, disassembled to their smallest components, and
decontaminated.
Assembly Area Correct Answer - Inspected, tested,
reassembled, packaged.
Storage & Distribution Correct Answer - Sterilized item
storage prior to transportation.
What pressure is the decontamination area under? Correct
Answer - Negative, to contain contaminants.
Which area are items inspected and identified for repair? Correct
Answer - Assembly area.
At what point can sterilized items become contaminated? Correct
Answer - Any time during handling, transport, or storage.
What are the two types of organizational structures? Correct
Answer - 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 two
governing bodies? Correct Answer - CSA and the PIDAC
(Ministry of Ontario Best Practices) document.
What does PIDAC stand for? Correct Answer - Provincial
Infectious Diseases Advisory Committee.
,6 external quality control bodies? Correct Answer - 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 Materials
Information Systems (WHMIS)? Correct Answer - WSIB
(Workplace Safety Insurance Board)
Study WHMIS pictograms. Correct Answer - OK.
Do all Hazard Classes and Categories require a Pictogram from
WHMIS? Correct Answer - No
How often do Safety Data Sheet (MSDS and SDS) need to be
updated? Not every 3 years. Correct Answer -
Where should SOPs be kept? Correct Answer - In a central
location. Electronic and physical.
What does QMS stand for? Correct Answer - Quality
maintenance systems.
Suffix Correct Answer - Means "after"
Microorganisms: Correct Answer - Unicellular, most aren't
harmful.
Spore Coat Correct Answer - Bacterial cells will produce a
spore coat to resist heat, drying, and chemicals.
Characteristics of Proteins Correct Answer - 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: Correct Answer - Aerobic, anaerobic,
and facultative anaerobe.
What are bacteria? Correct Answer - Single-celled organisms,
less than 1% cause disease.
Two types of bacterial cell walls: Correct Answer - Thicker
(gram positive), and thinner (gram negative). The "gram" term
comes from the gram stain test to determine successful sterilization.
What are viruses? Correct Answer - Smaller than bacteria,
non-living. Parasitic and uses other cells to reproduce.
What are fungi? Correct Answer - Mold, yeast.
What are MDRO? Correct Answer - Multiple drug resistant
organisms.
What are prions? Correct Answer - Infectious organic proteins.
Can remain infectious for years in a dried state, resists routine
sterilization and disinfection.
What are the components of bacterial microorganisms? Correct
Answer - Nucleic material, cytoplasm, membrane, cell wall,
flagella, fimbriae.
How prevalent are HAIs? Correct Answer - Healthcare
associated infections are the 4th leading cause of death.
What are the 5 modes of infection transmission? Correct Answer -
Contact (direct or indirect) - Droplet - Airborne - Vehicle - Vector
