Asepsis Flashcards
What are the two types of Asepsis?
Medical Asepsis and Surgical Asepsis
Which type of Asepsis has a sterile technique?
Surgical Asepsis
Which type of Asepsis has a clean technique?
Medical Asepsis
What are the three organisms that cause infection?
Bacteria, Virus and Fungi
The ability for an organism to cause infection depends on these five things
Number of organisms Virulence Function of the immune system Duration of contact Type of contact
What are the different ways a disease can be transmitted?
Direct
Indirect
Airborne
Droplet
What is the difference between a vector and a vehicle?
the difference between a vehicle and a vector is that a vehicle an inanimate object and a vector is a non human living animal.
What are the four stages of infection?
Incubation period
Prodromal Stage
Full stage of illness
Convalescent period
The incubation period is when
organisms are growing, colonization occurs here
What is colonization
where the organisms are building up in our body but we do not yet have the signs and symptoms
The stage where the individual may not know they are infectious is known as the
Prodromal stage
When you have signs and symptoms of the infection you are in what stage of illness?
The full stage of illness
The convalescent period is when
The individual is in recovery time. The individual has gone through treatment and the signs and symptoms are fading and returning back to normal state.
What are some of the factors affecting risk of infection?
Integrity of the skin/mucosal membranes pH level WBC count Immunizations Overall health Stress/anxiety Individual factors Invasive medical procedures- the more invasive the increased risk of infection
Define Iatrogenic Infection
Iatrogenic infection results from not using proper technique with a diagnostic procedure/medical treatment
Nosocomial Infection (HAI)
This is when a patient is admitted to the medical facility without an infection and develops one while under medical care.
Patient develops some sort of infection they did not have when they were admitted.
What are the two types of HAI’s?
Exogenous and Endogenous
Define an Exogenous Nosocomial Infection
When someone gets an infection from another person
Define and Endogenous Nosocomial Infection
When someone develops some sort of infection from themselves.
What does Medical Asepsis prevent?
Spread of microorganisms from person to person and prevents someone from becoming re-infected.
What does Medical Asepsis reduce?
Medical Asepsis reduces the number, growth or spread of microorganisms
What are the two precautions of Medical Asepsis? Why are they in place?
Standard precautions and Transmission based precautions. They are in place to help prevent/minimize the spread of pathogens.
Define standard precautions
These are precautions that everyone follows and are used with all patient care interactions.
Define Transmission based precaustions
These depend on the pathogenic agent and how it travels and is transmitted. i.e. contact, droplet, airborne
