infection control practices Flashcards
why is infection control important
DHCP and pt are exposed to a wide variety of disease cause organisms aka pathogens
guidelines based on treating all human blood & body fluids (including saliva) as potentially infectious
universal precautions
t/f; the same minimal infection prevention and control protocols must be used for all patients regardless of known or suspected infectious status
true
health Canada uses what term to describe the basic standard of IPC,
routine practices
standard precautions apply to contact with the following
blood, all body fluids, secretions, sweat, non-intact skin , mucous membranes
based on the concept that all pts are potentially infectious even when asymptomatic and that the same safety standards of practice should routinely apply to contact with blood, body fluids, and secretions
routine practices
4 principles of routine practices
risk assessment, hand hygiene, PPE, safe handling & disposal or shapes & contaminated waste
risk assessment
health status of pt, physical environment/working area
hand hygiene
use of plain antimicrobial soap w/ water, use of alcohol-based hand rub
personal protective equipment
use of PPE for both DHCP and pt
how to wash your hands
with antimicrobial soap and cool water. Use 70-90% alcohol based hand rub. Both methods are equally effective unless hands are visibly soiled or contaminated , in which hands should be washed with soap and water.
when hands should be washed
beginning of the day, after eating, after the bathroom, and if hands are contaminated, also before putting on gloves
alcohol-based hand rubs diff kinds
gels, foams, or rinses, more effective at reducing microbial flora than plain soap
when you can also use alcohol-based hand rubs
in between PPE removal such as masks, goggles, shield, gloves. Between pt , prior to tx
imortant considerations for hand hygiene
rings, long fingernails, fake nails should not be worn .
Fingernails
a common area of blood impaction contamination must be kept short less than 3-4mm
jewelry
No jewelry permitted in the workplace
PPE
Personal protective equipment protects the exposed tissue of DHCP from exposure to potential infectious material
protective clothing
to protect the skin and underclothing from exposure to saliva, blood, aerosol
when not to wear protective clothing
not be worn in staff longue areas or when workers are eating or consuming beverages
protective eyewear
worn to protect against damage from aerosolized pathogens, debris, splattered solutions. Should have both front and side protected.
Types of gloves in dentistry
examination gloves, utlity gloves, sterile gloves
procedure for re-gloving
excuse yourself, remove gloves, wash hands, add new gloves
t/f; if you leave operatory room for any reason during the treatment all PPE should be removed
true
when are utility gloves worn
the treatment room is cleaned and disinfected between patients, may be washed, disinfected, sterilized.
when are sterile surgical gloves worn
invasive procedures involving the cutting of bone or when gingival, mucosal, or dermal flaps are raised
when are over gloves used
may be worn over contaminated tx gloves to prevent contamination of clean objects handled during tx
irritant dermatitis
non-immunologic produces chemical irritation, becomes red, dry irritated. Sever case could result in cracked skin
type 1
most serious, life-threatening, coughing, wheezing, reaction to proteins
type 4
most common, delayed contact, red,itchy,rash ,bumps, chemical causes irritation
treatment for latex
no cure for latex should see their doctor.
standard of care designed to protect healthcare providers from pathogens that can be spread by blood or any other body fluid
standard precautions
type 1 latex allergy can cause
anaphylactic shock
