Module 3 Flashcards
Things you were thought about infection control
- Wash hands
- Don’t share food or drink
- Stay home if I’ll
- Cover cough/sneeze
Four major groups of microorganisms known to produce disease
- Bacteria
- Viruses
- Fungi
- Parasites
Bacteria
Minute one-cell organism, classified according to shape or how they group together
Indigenous micro flora are bacteria that normally live in the body
Many disease caused by bacteria are treated with antibiotics
We worry about drug resistance like MRSA
Viruses
Smaller than bacteria
Need a living host to live
Flu, aids, hepatitis are viruseS
Treated with antiviral drugs , antibiotics don’t work
Fungi
Yeasts and moldS
Require dark moist areas to grow
Candida causes thrush and vaginal infx
Moods cause ring worm and athletes foot
Treated with anti fungal drugs
Parasites
Are Protozoa
Malaria is caused by Protozoa
Lice is a parasite
Treated with anti protozoan drugs
How are organisms transmitted from one place to another?
1. Contact Direct: patient, person, animal Indirect: touching Droplets: direct- shaking hands Indirect- sneezing
- Vehicle
Via water, food or body fluids - Vector
Insects/animals
Health Canada identifies 5 routes of transmission
Contact Driplet Air borne Vehicle Vector
First like of defence
- Skin/mucous membranes
- Celia in nostril/resp
- Acidic conditions in GI tract
Second line of defence (specific)
- Inflammatory response- increase blood supply
2. Fever-increase WBC, phagocytosis response
Third line of response (specific)
- Antigens (cause disease)
2. Antibodies (cure disease)
What makes RT patient susceptible
- Age- elderly/very young have decrease immunity
- Nutritionally compromised- decreased appetite
- Treatment chemo/RT- decrease immunity
- Comorbidities
- Invasive procedures
3 signs/symptoms of an infection
- Fever
>38 over 4 hours - Lymph node swelling
- Inflammation
Nosocomial infx
Is one which a patient acquires during his stay in hospital
Hospital microorganisms: over crowding
Transmission: environmental factors like air flow
Compromised patients: poor immune systems
Patient has TB with designing lesions
Wash hands
Glove up (not it air borne)
Gown up
Mask for patient and staff
