Card Set Information
Asepsis Infection Prevention
Promoting Asepsis, Preventing Infection
Lines of Defense against nfxn.
: Skin. Keep moisturized. Intact. GI flora, tears.
: Immunity and symptoms of immune response.
: Antibodies, B-Cells, etc.
Factors that Increase Infection Risk
: Age, exposure, immunocompromised, environment, fatigue, nutrition, stress, artificial portal of entry.
6 Links in Chain of nfxn
All have to be present for nfxn to occure. Nurse's job is to break the chain.
What is a fomite?
Inanimate object that carries pathogens to the next host/carrier.
: Local Infection. What does it look like? Erythema, localized
: Exudate appears, sanginous (bloody), purulent (yellow, pus), serous (straw/white)
: Tissue replacement. Keloids.
Stages of nfxn
: Are you infectious before you have symptoms? Yup. Pathogens replicating but not enough to cause symptoms.
: “ I don’t feel so good.” Immune response has started.
: “ Please stay away from me.” Gloves off, knock down drag out fight pathogen vs immune response.
: Not too fast now. Relax. Take it easy. Let body repair.
: “Oh, if we only knew how long it would take.” Can take a really long time.
Identifications of Classifications
: through blood or lymph.
Local or systemic?
Pain or tenderness (L)
Warmth of the area on palpation (L)
Increased pulse and respiratory rate (S)
Healthcare Associated nfxn (HAIs)
Acquired in the hospital
$$$$$ because insurance will not pay hospital for treatment of pt who acquires nocicomial nfxn. Hospital cannot charge pt either. On the hook for their own bill.
Exogenous nosocomial infection – yuk!
Pathogen acquired from healthcare environment
Endogenous nosocomial infection – we all have it! Normal flora multiply and cause infection as a result of treatment
: usually due to physician or some type of therapy where sterile technique was not complete. Transfered from inanimate object.
What can you do to prevent HAI’s?
NPSG’s (National Patient Safety Goals)
: Use of appropriate hand hygiene
Prevention of multi-drug resistant organism infection
Prevention of central line associated blood stream infection
Prevention of surgical site infection
Drug Resistant Pathogens
MDRO’s (Mutli Drug Resistant Organism):
: Spore forming, sanitizing gels won't work.
Take home message:
WASH YOUR FREAKING HANDS ALL THE TIME!!!
Nursing interventions to promote asepsis
REDUCES the number of organisms
REDUCES the growth and spread of microorganisms
Objects are considered CLEAN
Preservation of STERILE field.
It's either sterile or it's not. No organisms = sterile.
Need at least 15 seconds with all of the above. Combined action --> reduction of microbes.
Implementing CDC guidlines for hygiene.
Protects healthcare workers from exposure
Decreases transmission of pathogens
Protects clients from pathogens carried by healthcare workers
Types of Tier I standards of precautions.
Mask and eye protection
Disposal of sharps
never thrown in trash, never recapped
Tier II precautions
: direct or indirect contact.
: Gloves, gown, mask. Mask can also be worn by you to prevent nfxn to pt.
: Gloves, gown, better (N95) mask (ie for pt with TB).
Basic principles of Isolation cases and hygiene
Wash hands before entering or leaving an isolation room
Dispose of contaminated supplies in a manner that will prevent the spread of microorganisms
Apply knowledge of disease process and mode of transmission when protective barriers are used
Protection of all persons during transport.
Pt. will typically be in negative pressure room. TB can be exposure, nfxn, and active. Can also be latent.
Other Isolation precaustions
EBSL (another resistant organsim)
Personal protective equipment (PPEs)
KNOW THE CDC GUIDELINES FOR PUTTING ON AND REMOVING PPEs.
