MDRAO Exam Prep, Medical Radiation Technologist
Certification, Comprehensive Study Guide
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
