Infection Control Flashcards
Patient, visitor and staff are examples of the _ of infection
source
Routine practices are determined by the _ with the patient not by the patient’s _
interaction ; diagnosis
In what circumstances would you use additional precautions along with routine practices
- droplet and airborne
- bacteria that is resist to multiple antibiotics
- organisms/ infections of significance
What is on the top of the health and safety hierarchy of controls?
elimination
What is the last resort on the health and safety hierarchy of controls?
PPE
What are engineering controls?
strategies such as placing a barrier between worker and customer
What are the 4 moments for hand hygiene?
- before initial patient contact
- before aseptic procedure
- after body fluid exposure risk
- after patient contact, when leaving the environment
_: should be used when in direct contact with any body fluids or moist substances/ exudate from wounds
gloves
_: should be used to protect the mucous membranes of the eyes, nose and mouth during procedures and patient care activities likely to generate splashes of sprays of blood, body fluids, secretions or excretions.
routine practices (mask, eye protection, face shield)
_- single room not required unless patient visibly soils environment
accomodation
_- all reusable equipment to be cleaned between patients
patient care equipment
_ - establish routine care, cleaning of surfaces and furniture, using hospital approved disinfectant.
environmental control
Risk of developing _ is between 6-36% if not vaccinated
Hep B
Risk of developing _ is about 1.8% after a cut or needle stick
Hep C
T/F: before depositing needles in SHARPS container you must recap
NO; DO NOT RECAP
T/F: in case of a patient with airborne precautionary measures their room door may remain open because other people only at risk when inside
False, door remain closed
T/F: door can remain open for patient with contact precautions
True
What is the sequence for putting on PPE?
- hand hygiene
- put on gown
- put on mask
- put on eye protection
- put on gloves
What is the sequence for removing PPE?
- remove gloves
- remove gown
- perform hand hygiene
- remove eye protection
- remove mask
- hand hygiene
What is a clean (class 1) surgical wound classification?
Clean aseptic surgical procedure in the OR where all precautions have been met
An example of a clean contaminated (class II) surgical wound classification?
Normal flora is interrupted
Example of contaminated (class III) wound?
gunshot
Example of dirty (class IV) surgical wound?
wounds that have resulted say from severe trauma like car accident or shark bite
_ are the most common bacteria associated with surgical site infections
staphylococci
_ items: will enter sterile body cavity or come in contact with sterile tissue or vascular system or blood will flow through them, ex. surgical instruments
critical items
_ : only come in contact with mucus membranes or non intact skin
semi-critical medical devices
_: items that come in contact with the intact skin and only require sanitization
non-critical medical devices
_: destroys all microorganisms and all bacterial spores
sterilization
_: destroys all microorganisms but not bacterial spores
high level disinfectant
_: reduce number of microorganisms, by mechanical means using thermal disinfection
pasteurization
