DANB ICE Test Review (Study Guide For
ICE Exam)Questions With Correct Answers
Low-Level Disinfectant: kills most vegetative bacteria, some fungi & some viruses, NOT
tuberculosis
Virucidal: kills some virsues
Suffix-cidal: to kill
Bactericidal: kills some bacteria
Fungicidal: kills some fungi
Tuberculocidal: kills tuberculosis bacterium
Sporcidal: kills high level bacterial endospores, (for non-heat resistant items)
Hospital Disinfectant: kills 3 main bacteria
,Chlorine Compounds: bleach=sodium hypochlorite, Intermediate level disinfectant at 1:10
to 1:100 dilution, mix fresh daily
Iodophors: iodine based, most are intermediate level disinfectant, prepare daily, NOT used
anymore
Alcohols: Isopropyl/ethyl- antiseptic and disinfect, rapid evaporation, poor cleaners, NOT
used as a surface disinfectant, used as a component in disinfectants
Phenols: aka- carbolic acid, first widely used disinfectant, intermediate level disinfectant,
detergent added to aid w/cleaning, dilute & mix fresh daily
Sterilization: process intended to kill all microorganisms and is the highest level of
microbial kill that can be achieved
Disinfection: less lethal, kills disease-producing microorganisms but NOT bacterial
endospores
Types of Sterilization: (3) heat, gas, liquid chemical
Categories of Pt Care Items: (3) critical, semi-critical, non-critical
Critical: penetrates soft tissue, contacts bone, enters into blood stream, ex. surgical
instruments, scalers, scalpels- MUST be cleaned and sterilized by heat
, Semi-critical: contacts mucous membranes, does not penetrate, ex. mouth mirror,
impression trays, amalgam condensor- heat resistant items must be cleaned & treated w/ high-
level disinfectants
Non-critical: contacts the skin, ex. blood pressure cuff, stethoscope- items are cleaned and
treated with a low-level disinfectant, intermediate-level disinfectant if visible blood
Universal Sterilization: all reusable instruments and handpieces are sterilized, NOT
disinfected, between use on patients
Steps of Sterilization: (7) transport, cleaning, packaging, sterilization, storage, delivery,
quality
Monitoring: (3) biological, chemical, mechanical
Biological Monitoring: aka- spore testing, place spore strip into sterilizers, if spores are
killed sterilizers are working
Biological spores: (2) geobacillus stearothermophilus, bacillus atropheus
CDC, ADA Recommend that Testing be Done: weekly
