Infection Prevention & Control Flashcards
(45 cards)
What are the 4 moments of hand hygiene?
- Before initial patient/patient environment contact
- Before aseptic procedure
- After body fluid exposure risk
- After patient/patient environment contact
How long should hands be washed for?
20 seconds
What are some examples of natural resistance/immunity?
-skin( not effective if cut)
-Mucous membranes ( trap foreign particles)
-chemicals like lysosomes (tears, acids)
-inflammatory response(blood flow=white blood cells=phagocytosis)
White blood cells try to destroy bacteria at cite of cut
Phagocytosis
Immunity by having been exposed
Ex. Chicken pox
Acquired immunity
Immunity by vaccination (long term immunity)
Active immunity
Transfer of antibodies or lymphocytes from an immune donor (can weaken over time and be short term)
Ex. Mother to child - placenta, breast milk…
Passive immunity
Protein substances formed in response to specific antigens
Antibodies
Produced by specific white blood cells - B cell
Any infection caused by recently recognized or feisty bugs
Ex. Ebola, influenza, west Nile, SARS, Covid
Emerging
Infections originating or taking place in a hospital, acquired in hospital
Appear 48 hours or more after hospital admission or within 30 days after discharge
Ex. Cdiff, MRSA, COVID
Nosocomial
Health care associated infections
Spread by contamination by blood
Ex. HIV hepatitis B/C, viral hemorrhagic fevers
Bloodborne
Infection control system to reduce the risk of transmission of infections from blood borne diseases, recognized sources of infections and other pathogens in the health care institutions
Standard precautions
Apply to: blood, bodily fluids, non intact skin, mucous membrane, contaminated equipment …

All the time, even when patient is not in room, 1 hour after discharge
What type of mask does a patient on airborne precaution wear?
Normal mask
Not n95
Infection resistance to a specific organism that occurs after an individual has been infected with the organism or that is confirmed from a vaccine
Acquired immunity
