PART 3 Flashcards
4 MAIN ROUTES OF TRANSMISSION
- CONTACT TRANSMISSION
- VEHICLE TRANSMISSION
- AIRBORNE TRANSMISSION
- VECTOR-BORNE TRANSMISSION
Direct physical transfer between an infected or colonized person and a susceptible host
DIRECT CONTACT TRANSMISSION
Has a strain of bacteria that have become a part of the person’s normal flora or bacteria
COLONIZED OR INFECTED PERSON
A person lacking immunity or resistance, and thus increasing the risk of infection
SUSCEPTIBLE PERSON
A susceptible host comes in contact with a contaminated object
INDIRECT CONTACT TRANSMISSION
• Droplets are usually sprayed no further than 90cm (3 feet)
• One is in close contact if one is within 90cm of another person
DROPLET CONTACT TRANSMISSION
• Serves as an intermediate means to transport and introduce an infectious agent into a susceptible host
e.g. handkerchief, toys, soiled clothing, utensils and surgical instruments
VEHICLE TRANSMISSION
Occurs by dissemination of droplet nuclei or dust particles that contain microorganisms and remain in the air
AIRBORNE TRANSMISSION
An animal, flying or crawling insects that serves as an intermediate means of transporting the infectious agent
VECTOR-BORNE TRANSMISSION
Protect your clothing and skin from contamination by a patient’s body substances
GOWNS
Used to protect the mucous membranes of the mouth, nose, and eyes from splashing of blood or body substances
MASKS, GOGGLES, & FACE SHIELDS
Most blood borne pathogen exposures are caused by accidental puncture with a contaminated needle or lancet
Strict adherence to all safety precautions is essential
SHARPS HAZARDS
May be required when collecting blood from patients who have airborne diseases, such as tuberculosis
RESPIRATORS
Freedom from disease-causing microorganisms
To decrease the possibility of transferring microorganisms from one place to another, asepsis is used
ASEPSIS
• “Clean Asepsis”
• Includes all the practices intended to limiting the number, growth and transmission of microorganisms
MEDICAL ASEPSIS
• Free of all microorganisms
• Practices that destroy all microorganisms and spores
SURGICAL ASEPSIS /STERILE TECHNIQUE
• I.V. administration of an undiluted drug directly into the systemic circulation
• Used when a medication cannot be diluted or in anemergency.
• Introduced directly into a vein by venipuncture or into an existing I.V. line
DIRECT IV PUSH
• Allow medications to be administered intravenously without requiring repeated needle sticks or a Continuous I.V. infusion.
• Needleless are preferred as they reduce the risk of needle stick injuries among health care workers.
