Infection control Flashcards
What does universal precaution mean?
assume all blood or bodily fluids are infected
How far should you be from sterile field?
Minimum, 12 in
Recommended, 18 in according to nurses guideline
What is a fomite?
Inanimate object that can carry and transmit infectious agents
What is a blood-borne pathogen?
Virus carried in the blood and transmitted by bodily fluids
Critical items
instruments, equipment, or devices that enter tissue or vascular spaces, or that blood flows through
*high risk of infection/contamination
require sterilization
eg: subdermal needles, surgical equipments, implants, catheters
Semicritical items
Instruments, equipment, or devices that have contact with mucous membranes or nonintact skin
require high or intermediate level disinfection (spores can stay)
eg: surface electrodes/respiratory therapy/anesth items, endoscopes/thermometers
Noncritical items
Instruments, equipment, or devices that have contact with intact skin
intermediate-low level disinfection
eg: surface electrodes, stethoscopes, bedpans, blood pressure cuffs, bed rails, toys, patient furniture
High level disinfection
Process that results in elimination of all viruses and vegetative microorganisms, tuberculosis, but not all bacterial spores
Can be achieved using germicides registered as EPA sporicides and tuberculocides, pasteurization, sodium hypochlorite, demand-release chlorine dioxide, and hydrogen peroxide
Intermediate level disinfection
process that results in the elimination of all vegetative disease producing bacteria, mycobacterium tuberculosis, most viruses and fungi, but not all bacterial spores
can be achieved using germicides with EPA registration as hospital disinfectants and tuberculocides, sodium hypochlorite, and with ethanol or isopropyl alcohol
Define nosocomial infection
infection originating within the hospital or patient care environment
*TB most common
Creutzfeldt-jakob disease (CJD)
transmissible spongiform encephalopathy known as a prion-based disease
passed by contact with tissue from certain organs or CSF and NOT blood
