Q

How is bacteria removed with hand washing?

Study These Flashcards
A

Bacteria is removed as a result of mechanical action of friction when rubbing and scrubbing

23
Q

When is hand washing frequently required?

Study These Flashcards
A

Before entering the ICU or operating suite

24
Q

What makes an antiseptic?

Study These Flashcards
A

Adding an antimicrobial or germicidal agent (ex: chlorohexidine gluconate)

25
What should you do after treating a patient with C.diff?
Wash your hands! Its a better means of decontamination than hand rubbing
26
What are potential contaminants during handwashing?
- Bar soap - Sink rims - Waterspout - Basin - Towel - Dispenser - Faucet handle - Etc.
27
Isolation precautions are linked to what?
The method by which pathogens are transmitted
28
Where are isolation precautions indicated?
In the medical record
29
When entering the patients environment the caregiver must adhear to specific actions such as...
- Contact (direct or indirect) - Droplet (direct or indirect - respiratory droplets) - Airborne
30
Where can you find PPE, biohazard bags, and other necessary materials and supplies?
The cart outside the room
31
Where can you find directions for your isolation precautions?
Just outside the room, just inside the room, or in an anteroom
32
What was sterile field designed for?
maintain sterility of objects within the field (dressing, bandages, instruments)
33
What are the four rules of asepsis?
1. Know which items are sterile 2. Know which items are not sterile 3. Separate sterile items from non-sterile items 4. If a sterile item becomes contaminated, remedy the situation immediately (discard the item and re-establish the sterile field)
34
What are examples of PPE?
- Gloves - Gown - Mask or respirator - Protective eyewear (shield, safety glasses)
35
T/F - You should take your PPE off outside of your patients room.
False. Do not wear PPE outside of a patients room.
36
What are the two methods to clean an item?
- Disinfection - Decontamination
37
Disinfection has three categories (high, intermediate, low). What falls under each category?
- High: everything except high numbers of bacterial spores - Intermediate: most viruses, fungi, vegetative bacteria, TB - Low: most bacteria, some viruses, some fungi
38
What does it mean to decontaminate something?
To remove, inactivate, or destroy blood-borne pathogens on a surface or items to the point where they are no longer capable of transmitting infectious particles
39
What are contact precautions recommend for?
Transmission of infectious agents which are spread through direct or indirect contact with patients or the environment a patient is in (ex: C. diff)
40
What PPE do contact precautions require?
- Gown - Gloves - Hand washing - Don PPE Before entering and Doff before exiting
41
What are droplet precautions recommended for?
Transmission of pathogens spread through close respiratory or mucous membrane contact with respiratory secretions (ex: flu)
42
What PPE do droplet precautions require?
Donning a surgical mask before entering the room
43
What are airborne precautions recommended for?
Infectious agents that remain infectious over long distances suspended in the air (Ex: TB and chickenpox)
44
What PPE do airborne precautions require?
- N-95 fitted mask - Specifically ventilated room - Closed door
45
What responsibilities does the healthcare facility have?
- Educate employees on methods of transmission and prevention - Provide safe and adequate PPE - Educate on standard precautions - Provide proper disposal containers - Offer HBV vaccine - Provide follow-up care to employees exposed to communicable diseases
46
What are OSHA guidelines?
- Use PPE provided by facility - Dispose of wastes in proper containers - Dispose of sharps in proper containers - Keep work and patient care areas clean - Wash hands before and immediately following removal of gloves - Immediately report any exposures or personal illnesses
47
What is MRSA?
Methicillin-Resistant Staphylococus Aureus - a staph infection that is difficult to treat because it is resistant to some antibodies - Spreads easily in hospitals - Many healthcare providers are carriers - Can cause sepsis and death if left untreated
48
What kind of precautions does MRSA require?
Contact
49
What is VRE?
Vancomycin-Resistant Enterococci - antibiotic resistance to vancomycin of enterococci bacteria
50
How do patients get VRE?
- Usually happens with long term antibiotic use - Often in those hospitalized or with weakened immune systems - Spreads through contact with contaminated surfaces
51
What is C-diff?
Clostridioides difficile infection - a bacteria that causes severe and/or life threatening diarrhea - side effect of taking antibiotics
52
What are symptoms of C-diff and how does it spread?
- Symptoms include diarrhea, fever, stomach pain, loss of appetite and nausea - Spreads through person to person contact
53
What are examples of ancillary staff?
- Diagnostic: laboratory tests, radiology, genetic testing, diagnostic imagine - Therapeutic: PT, PTA, OT, COTA, SLP, RT, rehab psychology, dietician, massage, rehab aides - Custodial: environmental services, food services
54
How can you communicate with ancillary staff?
- Verbal: tone, volume, inflection - Nonverbal: body position, facial expression, active listening - Written: lay language, typed, handwritten
