Week 3 Flashcards
It is caused by microscopic organism that penetrate the body natural barriers and multiply to create symptoms that can range from mild to deadly
INFECTIOUS DISEASES
Give three examples of infections
Measles
Tuberculosis
Common cold
Human resevoirs include:
Patients, Healthcare personnel, Household members, Visitors
It is someone who is not vaccinated or otherwise immune, or a person with a weakened immune system who has a way for the germs to enter the body.
Susceptible person
Devices like _____________ and __________________ can provide an entryway, whereas a healthy immune system helps fight infection
IV catheters and surgical incisions
The most common mode of transmission
Contact Transmission
Contact Transmission is divided into two subgroups:
Direct and Indirect
Occurs when microorganisms are transferred from one infected person to another person without a contaminated intermediate object or person
Direct Transmission
Involves the transfer of an infectious agent through a contaminated intermediate object or person. In the absence of a point-source outbreak, it is difficult to determine how it occurs
Indirect Transmission
are intended to be applied to the care of all patients in all healthcare settings, regardless of the suspected or confirmed presence of an infectious agent.
Standard Precaution
LIST OF PPE
Lab Gown
Mask
Goggles
Gloves
Hair Cap
is the practice of grouping together patients who are colonized or infected with the same organism to confine their care to one area and prevent contact with other patients
Cohorting
How many meter is need in social distancing?
one meter
the patient placement concerns focus on protecting other in the home from exposure to an infectious household member
HOME CARE
Use _______________ for patients with known or suspected infections that represent an increased risk for contact transmission
Contact Precaution
are intended to prevent transmission of pathogens spread through close respiratory or mucous membrane contact with respiratory secretions.
Droplet Precaution
prevent transmission of infectious agents that remain infectious over long distances when suspended in the air
Airborne Precaution
introduced the concept of aseptic surgery using carbolic acid, now called phenol
Joseph Lister
oldest disinfectant
Phenol
refers to the destruction of all forms of life, including bacterial spores. it is an all or nothing process
Sterilization
refers to a process that eliminates a defined scope of microorganisms, including some spores
Disinfection
A substance applied to the skin for the purpose of eliminating or reducing the number of bacteria present is reffered to as:
Antiseptic
The organisms known today to be the most resistant to the actions of heat, cehmicals, and radiation are:
prions
How many mins is the contact time for disinfection?
20 mins
