Asepsis and Infection Flashcards
Communicable/contagious/community acquired disease
diseases that can be transferred to others
Aerobic bacteria
needs O2 to survive
Anaerobic bacteria
does not need O2 to survive
What are bacterias treated with?
Antibiotics
What are the 3 types of mycotic fungi?
Superficial, Intermediate, and systematic.
Systematic Fungi appears on…
inside the body, and on skin
Candidiasis
Vaginal yeast
Tinea Corpus
Ringworm
Tinea Pedis
Athletes foot
What do you treat Candidiasis with?
Diflucan, monistat cream
Systematic Fungi
infects deep tissue and organs, or in the bloodstream
Helminths
Worms- some ender the body in an egg state, and mate and reproduce after they invade a species.
What do prions lack?
DNA/RNA
Spores
type of bacteria that is very difficult to get rid of, such as MRSA and VRA.
What causes antibiotics to no longer work?
Not taking all of the amount prescribed, administering to livestock, using as treatment of minor viruses such as a common cold.
What are the links in the chain of infection? (1-3)
- Infectious agent
- reservoir for growth and reproduction
- exit route from the reservoir
what are the links of the chain of infection? (4-6)
- mode of transmission
- port of entry
- susceptible host
Direct contact
physical touch, sexual intercourse
What is the distance of a droplet?
Less than 3 ft.
What is the distance of airborn movement?
More than 3 ft.
Droplet
Moist particles
Vehicle transmission
transfer of microorganisms present in water, food, medication, or equipment (inanimate)
Vector
Transfer of microorganisms from an infected animal or bug (living organism)
4 common routes for the portal on entry
respiratory, GI tract, urinary, reproductive, breaks in skin.
How to interrupt chain of infection
- pathogen identification
- asepsis and hygiene
- control of portals of exit
Nosocomial infections
infection acquired when in the hospital
Common sites of a nosocomial infection
- urinary tract due to catheters
- lower respiratory tract
- surgical wound infections
What is an infection acquired while in the hospital called?
Nosocomial infection
how to prevent a UTI
avoid catheters
How to prevent a lower respiratory tract infection
prevent aspiration, respiratory therapy, sterile field when suctioning
how to prevent a surgical wound infections
antibiotic treatment post-op, sterile dressing changes
