Resevior
-
6 Things required for an organism to survive.
- Food
- Oxygen
- Water
- Temp
- pH
- Light
-
6 Types of Portals of Exit
- Skin
- Respiratory tract
- Urinatry tract
- GI tract
- Reproductive tract
- Blood
-
Three types of defnce against infection.
- Normal flora
- Body systems defence
- Inflammatory response
-
This occurs when broad-spectrum anitbiotics eliminate normal flore, not just those causing infection, reducing the body's defenses.
Suprainfection
-
3 things that can trigger an inflammatory response
- Physical
- Chemical
- Microorganisms
-
3 Steps to the inflammatory response
- Cellular response
- Formation of exudates
- Tissue repair
-
These WBC are the first line of defence from microorganisms
Neutrophils
-
Process that involves destruction and absorption of bacteria
Phagocytosis
-
These are the 2 WBC that are specialized in phagocytosis
-
The process in which the body increases the number of circulating WBC in response to WBC leaving the blood vessels.
Leukocytosis
-
An HAI acuired from a diagnostic procedure
Iatrogenic infection
-
An HAI acquired from surgery
Exogenous Infection
-
An HAI acquired when part of the clients normal flora becomes altered and an overgrowth results.
Endogenous Infection
-
Range for a normal WBC count
5000-10000/mm3
-
Percent of WBC that are Neutrophils
55-70%
-
Percent of WBC that are Lymphocytes
