Safety in Phlebotomy I and II Flashcards
a patient get infected in 48 hours or more after admission or within 30 days after discharge
nosocomial infection
nosocomial infection is also known as
healthcare-associated infection/hospital acquired infection
it is restricted to one area of the body only
local infection
it affects the entire body
systemic infection
types of infection
nosocomial, local, and systemic
results when a microorganism (microbe) is able to invade body, multiply, and cause injury
infection
infection that can spread from person-to-person
communicable disease
six components of chain of infection
reservoir, susceptible host, means of transmission, portal of exit, portal of entrance, infectious agent
it is the causative agent that causes infection
infectious agent
it is the source of an infectious agent and where microbe survives
reservoir
used by an infectious agent to leave a reservoir
portal of exit/exit pathway
it is the method an infectious agent uses to travel from a reservoir to a susceptible host
means of transmission
five means of transmission
airborne, contact, droplets, vehicle, vector
contact transmission have two types:
indirect and direct contact
it is a type of contact transmission that is transferred via objects
indirect
it is a type of contact transmission that is transferred from source to susceptible host
direct contact
it is a mean of transmission that infects when you’re in contact with a mucous membrane and only travels by no more than 1 meter
droplet transmission
droplet transmission can be transferred via
sneezing, coughing, or talking
a mean of transmission through contaminated food/water/drugs
vehicle transmission
contaminated water causes
parasitic/cholera infection
contaminated food causes
food poisoning
blood and body fluid contact can cause
HIV/AIDs or Hepatitis
common cause of infection for phlebotomist while doing their job
accidental needlestick
transmission through insects
vector transmission
two types of vector tranmission
biological, mechanical
it is a vector transmission through biting
biological vector transmission
a vector transmission by landing on food as an example
mechanical vector transmission
it is a mean of transmission that spreads droplets by coughing, sneezing, or talking and inhalation of droplets
airborne transmission
it is the entry into a susceptible host
entry pathway/portal of entry
portal of entry can be exposed by:
catheterization, venipuncture, fingerstick, and heel puncture
entry pathway of healthcare workers can be exposed via
splash and spill of infectious specimen or by needlestick (most common)
someone with decreased ability to resist infection
susceptible host
factors that affect susceptibility
age, disease, medication, and immune status
it is an infection that can come from the source’s own flora
autogenous infections
it was developed in 1985 by Centers of Disease Control and Prevention as a response to the increase blood-borne diseases (AIDS and Hepatitis B)
Universal Precautions
Universal precautions was the basis of what
Standard precautions
States that any patient has the potential to be infected with pathogens
Universal Precautions
Universal precautions evolved into
Body Substance Isolation (BSI)
states that gloves are to be worn when in contact with any body substance
BSI
combination of BSI and Universal Precautions
Standard Precautions
It states that PPEs and barrier controls are to be maintained
standard precautions
goal of standard precautions
to reduce the risk of transmission of microorganism from both recognized and unrecognized sources of infection
To reduce exposure risk, these are the list of available preventions
engineering controls, work practices, housekeeping, HBV vaccination, private rooms, ppe
these are physical and mechanical devices available to reduce/eliminate potential transfer of infectious diseases
engineering controls
this engineering control steam-sterilize contaminated materials
autoclaves
It is an engineering control that has HEPA filter that intakes and exhaust air and recirculate filtered air into laboratory and ensure sterility
Biological Safety Cabinet
an engineering control that has no filter and exhaust chemical fumes outside laboratory; suitable for chemicals and non-sterile work; never used for infectious agents
fume hoods
an engineering control device that serves as storage for flammable and corrosives; limited to small quantity as possible
chemical storage cabinets
an engineering control device that is used when eyes are exposed to chemicals
eyewash station
an engineering control device that is used when chemicals are spilled into skin/clothing and should be installed wherever corrosive chemicals are used
safety showers
practices that are incorporated to all healthcare associates
work practice controls
the most important way to prevent spreading of infection
Handwashing
used to clean skin surface in place of hand washing
alcohol-based hand cleaners
it is the responsibility of all healthcare associates. Involves cleaning up spills and decontaminating soiled areas immediately with disnfectant
housekeeping
it should not be picked up with hands
broken glass
reduces the possibility of transmission by separation
private rooms
anyone who can enter/leave can wash hands and change into ppe
anteroom
used to protect from infectious material and must be provided by employer free of charge
personal protective equipment
ppe equipments
gloves, mask, face shield, protective eyewear, lab gown, safety showers, appropriate footwear, eyewash stations
ppe equipment that should be worn first
gloves
used to prevent transmission of infectious agents through air
face masks
necessary when soiling of clothes is possible while taking care of patients and should be fluid resistant
laboratory gowns
removal of lab gowns should be
inside out
sequence of donning ppe
gown first, mask, goggles, hand-wash, gloves
sequence for doffing ppe
gloves, hand-wash, face-shield, gown, mask
it limits the amount of time a patient has to spread an infection
isolation techniques
In the 1970’s, the CDC recommended the hospitals used one of seven isolation categories, this is a practice called?
category-specific isolation
this isolation technique would occur after many are exposed
category-specific isolation
this category-specific isolation subsection are for patients with a contagious disease like diptheria, chickenpox, and pneumonia
strict isolation
this category-specific isolation subsection are or patients with a disease that can be transmitted through direct contact like scabies (caused by mites or Sarcoptes Scabies)
contact isolation
a category-specific isolation subsection which are for patients with a disease that can be transmitted through air like mumps, pertussis, and rubella
respiratory isolation
this category-specific isolation subsection is also called ACID-FAST BACILLUS (AFB)
Tuberculosis Isolation
this categorical-specific isolation subsection is sometimes called wound and skin precaution and is for patients with open wounds
drainage/secretion precautions
a category-specific isolation subsection that are for patients with severe diarrhea due to contagious bacteria such as Salmonella, Shigella, Vibrio Cholerae and are transmitted by feces
enteric precautions
in this category-specific isolation subsection, patients are protected from healthcare workers
protective/reverse isolation
Established in 1983 to overcome the short-comings of category-specific isolation and based on the modes of transmission of common diseases
disease-specific isolation
new category that was added in disease-specific isolation
blood and body fluid precaution
this category-specific isolation subsection was eliminated in disease-specific isolation because of its inefficiency
protective/reverse isolation
in disease-specific isolation, this subsection of category-specific isolation was updated and recommended to use private rooms and air pressure with the use of HEPA filter respirators instead of face mask
tuberculosis isolation
isolations were revised again in 1996 and are intended for patients diagnosed with/or specific transmissible diseases
transmission-based precautions
three categories of transmission-based precautions
airborne, droplets, contact transmission
OSHA stands for
Occupational Safety and Health Administration Standards
it investigates the possibility of unsafe practices in the work environment and is the result of Occupational Safety and Health Act of 1970
OSHA Standards
includes non-intact skin (dermatitis, hangnails, cuts, abrasions, chafing, acne)
