MDA 130

Disease definite pathologic process having a distinctive set of symptoms & course of progression.
Medical Asepsis Removal or destruction of microorganisms.
1-to understand & practice medical asepsis at all times using specific practices & procedures to prevent disease transmission. 2-teach pts& their families about tech. to use at home preventing trans. of diseases. What are the 2 goals for MA's in med office?
Microorganisms microscopic living organisms.
Normal flora microorganisms normally found in the body; aka Resident flora
Infection invasion by disease- producing microorganisms.
Pathogen disease- causing microorganism.
Disease2 Producing microorganisms are referred to as pathogens & are classified as bacteria, viruses , fungi, or protozoa.
Bactericidal Substance that kills or destroys bacteria.
Transient Flora (travels) microorganisms that do not normally reside in a given area; transient flora may or may not produce disease.
Resistance (defense) body's immune response to prevent infections by invading pathogenic microorganisms.
Virulent (Violent) highly pathogenic & disease producing; describes a microorganism.
Spores Bacterial life from that resists destruction by heat, drying, or chemicals. Spore-producing bacteria include botulism & tetanus.
Aerobes microorganism that requires oxygen to live & reproduce.
Anaerobes bacteria that require the absence of oxygen for growth & reproduction.
Carriers person infected w/ a microorganism but w/o signs of disease.
What are the 5 infection cycles?
Direct Contact between the infected reservoir host & the susceptible host produces direct transmission .
Indirect Contact may occur through contact w/ a vehicle known as a Vector.
Vector (biologic ) a living, nonhuman carrier of disease, usually an anthropod;;.(mechanical) a carrier of disease that does not support growth ; ex: contaminated inanimate objects.
Anthropod an invertebrate animal of the large phylum Arthropoda, such as an insect, spider, or crustacean.
Viable Capable of growing & living .
Asymptomatic W/o any symptoms.
OSHA-Occupational Safety & Heath Administration- federal agency that oversees working conditions, w/ that mission to protect employees from work-related hazards.
CDC-Centers fro Disease Control & Prevention- U.S. Federal agency under the Dept. of Health & Human Services that works to Protect Public Health & Safety.
"Clean Technique " maintain pathogen-free conditions to prevent transmission between people or objects & people.
Handwashing What is the most important med Aseptic tech. to prevent transmission of pathogens??
Diff between med asepsis & surgical asepsis??
Sterilization, Disinfectants(Germicides), Sanitation. What are the Levels of Infection Control??
Sterilization Highest level- process, act or tech. for destroying microorganisms using heat, water, chemicals, or gases.
Disinfection Med Level- killing or rendering inert most but not all pathogenic microorganisms.
Sanitation Process used to lower the # of microorganism on a surface by cleansing w/ soap or detergent, water, & manual friction.
Germicide Chemical that kills most pathogenic microorganisms; disinfectant.
Exposure Risk Factors conditions that tend to put employees at risk for contact w/ bio hazardous agents such as blood borne pathogens.
PPE (Personal Protective Equipment) equipment used to protect a person from exposure to blood or other body fluids.
Immunization actor process of rendering an individual immune to specific disease.
Exposure Control Plan written plan required by the OSHA that out lines an employers system for preventing infection.
Biohazardous describing a substance that is a risk to the health of living organisms.
Postexposure testing lab tests that may be performed after a person comes in to contact w/ a biohazard.
Standard Precautions usual steps (set by CDC) to prevent injury or disease .
Hep B. it can live on surfaces longer (more than a wk) What is more viable Hep B or HIV??
w/ dilute bleach solution. How to kill HBV??
via blood & body fluids. How is HBV & HIV transmitted??
Prophylaxis means preventive
Antibody means defense mechanism
Titers blood tests for your immunity
Propholative means you take just in case
