Lab 4 Flashcards
Medical asepsis
Measures for reducing and preventing the spread of microorganisms
Examples of routine precautions
Hand hygiene
Point of care risk assessment
Respiratory hygiene
Risk reduction strategies
Education of staff, clients, visitors
Point of care risk assessment
Determine potential for exposure to pathogens
Assess infectious risk
Determine need for PPE
Contact precautions vs contact plus precautions
Plus requires full handwashing, while regular contact gel is ok
Contact precautions
Due to wound or infection
- requires gown and gloves
Droplet precautions
For coughs (COVID/flu)
- requires mask with shield
- recommended use of gown and gloves
Droplet AND contact precautions
- cough + wound
- requires mask width shield, gown and gloves
Airborne precautions
For airborne illnesses (TB/chicken pox)
- requires N95 respirator

Infection stages (5)
Incubation period
Prodromal stage
Illness stage
Decline
Convalescence
Infection stage: incubation period
Time from exposure to onset
- no symptoms yet
- not infectious
Infection stage: prodromal stage
Stage where the infection is replicating
- now infectious
- mild, non specific symptoms start (low grade level, fatigue)
Infection stage: illness stage
Time when a person shows apparent symptoms of an infectious disease
- infectious
Infection stage: decline
decline of symptoms, immune system is successful in defence
- still infectious
- slow return to normal
- increased risk of developing new infection in this stage due to weakened immune system
Infection stage: convalescence
Final stage of infection
- symptoms resolve - normal
- no longer infectious
