Who is responsible for receiving all reports concerning infectious and communicable exposure, and initiating precautions for the type of organism present?
Infection Control Practitioner
What are the two types of aseptic technique?
Medical asepsis and Surgical Asepsis
What aseptic technique is known as the clean technique/
What type of contact occurs person to person or physical contact between sources and susceptible host (e.g. fecal, oral)?
What type of contact involves contact with contaminated inanimate objects (e.g. needles, utensils, hospital equipment)?
What patients are at risk for HAIs?
Pt's with surgical incisions, artificial airways, urinary catheters, and IV lines
What is the main reason why Patients get HAIs?
medical personal did not perform proper hand washing or did not wash between patients
What are some examples of droplet transmission?
projections from nasal mucosa, mouth, or conjunctiva
What are examples of airborne transmissions?
coughing and sneezing
In regards to the chain of infection, what are some ways infections are transmitted?
Touch/contact, vector, droplet, airborne
What is the most effective barrier to infection?
What are some conditions that make someone a susceptible host?
age, weak state of health, broken skin
What actions should be taken if exposed to a possible communicable disease?
Notify immediate supervisor
Seek proper Medical evaluation
Notify immediate supervisor and public health of any duty restrictions or limitations
What are the four rules of surgical asepsis?
Know what is sterile
Know what is not sterile
Separate sterile from unsterile
Remedy contamination immediately
a ____ inch margin around the the edge of a sterile field is considered contaminated
How long are paper wrapped sterile packs good for?
Can sterility be indefinite if sealed in a plastic outer wrapper?
yes, follow local policy
What do thermal/chemical indicators actually indicate?
only that the instruments were exposed to the sterilizing process, does not indicate that they are stills sterile
What is the most common type of chemical indicator for sterility?
What is the only true indicator of sterility?
What are the four most common methods of sterilization?
Ethylene Oxide (ETO)
Hydrogen Peroxide Plasma
What type of sterilization involves steam and an autoclave?
What type of sterilization destroys microorganisms and spores, is used for heat sensitive items where good penetration is essential and the gas is toxic so aeration is needed?
What type of sterilization uses oxidizing properties allow for the destruction of a wide range of pathogens and is used on heat sensitive items?
Hydrogen peroxide Plasma
What type of sterilization is done either by exposure to a toxic gas or prolonged immersion in a chemical disinfectant?
When cleaning instruments prior to sterilization what are some common methods?
1:10 chlorine bleach
What type of bag need to be used to dispose of biohazardous waste?
impermeable red, plastic bag labeled with the date and the word "biohazard" or "medical waste"
When washing hands, what are the two cleansing agents?
Soap/detergent - aids in the removal of organisms
Antibacterial - kills or suppresses the growth of microorganisms
What are the steps when sterilizing equipment?
Decontaminate instruments manually
Disinfect instruments after cleaning
Prepare for Sterilization after cleaning
Dispose of Contaminated materials
Why is it important to decontaminate instruments manually before sterilizing?
Organic material can be backed on which would destroy the instrument
When decontaminating instruments how should they be sorted?
by type and weight
After cleaning instruments, how do you prepare them for sterilization?
Lay open on absorbent pad, allow to dry, place in bin designated for central sterile supply and complete paperwork
When washing hands, what do you use to clean fingernails?
What term describes direct contact with another persons's body fluid or any item contaminated with another person's body fluids?
