Q

Five principles of asepsis

A
  1. Know what is dirty
  2. Know what is clean
  3. Know what is sterile.
    4 keep the 3 conditions separate
  4. Remedy contamination immediately

A

Negative (lesser) pressure

19

A

Positive pressure

20

Inanimate object that can transmit bacteria

21

T- 60-65°f (16-180c)
Humidity- 30-60%
Air exchange- 10

22
Q

General work area requirements

A

T- 68-73°f (20-23°)
Humidity -30-60%
Air exchange- 10

23

25
Q

Causative agent

A

Chain of infection
Micro. That causes infectious disease

Bacteria, vines, fungus, Protozoa or prion

26
Q

Reservoir

A

Chain of infection
Place where micro. Can survive.

Carrier. Organism infected but no symptoms displayed can still transmit tocthers

27
Q

Portal of exit

A

Chain of infection
Path which infectious agent leaves resovior

Coughing, sneezing, urine vaginal secretions, semen, vomit, stool, mucusmemb, wound, blood, transplacental

28
Q

Mode of transmission

A

Chain of infection
Meth of transfer of infectious agent from resavior to susceptible host

Direct, indirect ( through object), droplets, airborne nvectorborre, pathogenic transmission→ interrupted with proper hygiene and PPE, etc.

29
Q

Portal of entry

A

Chain of infection
Path used by infect. Agent to enter most

Rest, genitourinary, gi, skin and mmb, transplacental
Parenteral= something put inside body but not swallowed (ex. injection)

30
Q

Susceptible host

A

Chain of infection
Person or animal that lacks ability to resist infection by agent

Colonization= when micro. Live on or in host and do not harm or damage

31
Q

Chain of infection

A

Causative agents → reservoir→ portal of exit → mode of transmission → portal of entry → susceptible most

32
Q

Characteristics that make micro. Capable of causing disease

A
  • Invasiveness: ability to invade and cause damage
  • Pathogenicity: to gain entry and cause dz.
  • Virulence: degree of pathogenicity
  • infectious dose: quant ay of micro. Required
  • Viability in a free state: a bitty to survive outside host
  • ability to develop resistance to antimicrobial agents
33
Q

Interrupting chain

A

Use aseptic technique to avoid cross contamination, physically removing contaminated substances, use effective disinfection and sterilization

34
Q

Susceptible host factors

A
  • age
  • dz. History
  • meds and tx→ compromise immune system
  • Trauma
