Prevention / Control Flashcards
Bioterrorism agent
Category B
Moderately easy to disseminate
Moderate to low morbidity rates
require CDC’s diagnostic capacity and disease surveillance
Examples water safety food safety Q fever typhus fever Ricin toxin
Bioterrism agent
Classification A
High priority agents pose a risk to national security
Easily transmitted person to person
High mortality rates
Major public health impact special action for public health preparedness
Examples anthrax botulism plague smallpox tularemia
Bioterrorism agent
Category C
Emerging pathogens that could be engineered for mass dissemination in the future because of availability is a production potential for high morbidity and mortality
Anthrax
Not transmitted from person to person
must follow standard precautions
treat with antibiotics for six weeks
What is Brucella
Transmitted from person to person by contact with draining lesions tissue transplantation and sexual contact
standard precautions
use PPE when caring for patients that have lesions
What is botulism
Not transmitted person-to-person follow
standard precautions
What is Cholora
Transmitted by drinking water or food that has been contaminated with feces
standard precautions
What is Glanders
Spread person a person through skin abrasions nasal and oral Makossa services or by inhalation
Standard precautions
What is plague
Pneumonic plague transmitted person-to-person by a respiratory droplets standard precautions plus droplet for 72 hrs
Mask within 3 feet of patient
private room
What is Q fever
Standard precautions
person-to-person transmission is very rare
What is ricin
Not transmitted person-to-person
standard precautions
What is smallpox
Airborne and contact with negative pressure room transmitted
person a person by respiratory or aerosolization
patient is infectious until all scabs have separated
What is Tularemia
NOT transmitted person to person
Standard precautions
Lamaur Christmas where I protection surgical gloves protective down shoe covering when working with pure bacterial cultures
Seven factors of sterilization
Duration of exposure
Number and location of micro organisms
resistance of micro organisms concentration
potency of disinfectants
physical & chemical factors organic and inorganic matter
Biofilm
Categories of micro organisms that are resistant to germicidal sterilization processes
GROUP A
Group a comprises a vegetative bacterial cells, fungi, lipophillic viruses which are the easiest to kill
Categories of micro organisms resistant to germicides and sterilization
GROUP B
Group B includes tubercle bacilli and hydrophilic viruses which are more difficult to kill
Categories of micro organisms that are resistant to germicides and sterilization processes
GROUP C
Group C includes bacterial spores such as bacillus & Clostridum.
The destruction of sports require high concentrations and long contacts on for most sporadical disinfectants
Parameters of steam sterilization
Pressure
Temperature- 250 F (121C) or 272 F (133C)
Time
Moisture- 100% humidity
Gravity sterilizes in CSP at PMH
High speed vacuum sterilizes
Vacuum pump removes the air fri the chamber before the stream is admitted, reducing the penetration time and total cycle time
VAP prevention
Elevate HOB 30-45 degrees Daily sedative interruption and assessment of readiness to extubate Peptic ulcer disease prophylaxis Daily oral care with CHG DVT prophylaxis
