Asepsis and Infection Control Flashcards
are directly involved in providing a biologically safe environment
Nurses
freedom from disease-causing microorganisms
Asepsis
Two Types of Asepsis:
- Medical Asepsis/clean technique
- Surgical asepsis/aseptic technique
all practices intended to confine a specific microorganism to an area.
Medical Asepsis/clean technique
practices that keep an area or object free from all microorganism
Surgical asepsis/aseptic technique
state of infection and can take many forms, including
septic shock.
Sepsis
Types of microorganisms that cause infections: FOUR CATEGORIES:
- Bacteria
- Viruses
- Fungi
- Parasites
The most-common infection-causing microorganism
BACTERIA
Can be transported through air, water, food, soil, body tissues and fluids, and inanimate objects.
BACTERIA
- Consist primarily of nucleic acid
- Must enter living cells in order to reproduce
VIruses
Common examples of Viruses:
- Rhinovirus (colds)
- Hepatitis
- Herpes
- HIV
- SARS-CoV-2
virus that causes colds
Rhinovirus
Yeasts and molds
FUNGI
yeast considered to be normal flora in the human vagina
Candida albicans
- Live on other living organisms.
- Protozoas
PARASITES
Examples of Parasites:
- Malaria
- Helminths (worms)
- Anthropods (mites, fleas, ticks)
microorganisms invades body part where the host’s defense
mechanisms are ineffective; pathogens causes tissue damage
INFECTION
Types of Infection
- Local
- Systemic
- Acute
- Chronic
Limited to a specific part of the body
Local
The microorganism spread and damage different body parts
Systemic
- sudden
- Last a short time
Acute
- Slowly
- May last months or years
Chronic
blood culture is (+) of microorganisms
Bacteremia
bacteremia resulting in systemic infection
Septicemia
Associated with the deliver of health care services in a health care facility
NOSOCOMIAL INFECTIONS
types of NOSOCOMIAL INFECTIONS
Endogenous or exogenous
Common microorganisms in NOSOCOMIAL INFECTIONS:
- Escherichia coli
- Staphylococcus aureus
- enterococci
