Aubf Safety Flashcards
The clinical laboratory contains a
variety of safety hazards, many of
which are capable of producing
serious injury or life threatening
disease.
Laboratory safety
To work safely:
– learn what hazards exist
– the basic safety precautions
– apply the basic rules of common
sense
Safety procedure manuals
– available in the laboratory
– describe the safety policies
– updated and reviewed annually by the laboratory director.
Safety procedure manuals mandated by the
Centers for Disease Control and Prevention (CDC) and the Occupational
Safety and Health Administration (OSHA)
Hazard that indicates Proper hand hygiene, correct
disposal of contaminated materials,
and wearing personal protective
equipment (PPE) are of major
importance in the laboratory.
Biological hazard
major importance in the laboratory according to Biologic Hazards
Proper hand hygiene
correct disposal of contaminated materials
wearing personal protective equipment (PPE)
It states that all patients are considered
to be possible carriers of bloodborne
pathogens.
Universal precautions
The guideline recommends UP
Wearing gloves
Wearing face shield
Excluded urine and body fluids
Standard Precautions are as follows
- Hand hygiene
- Gloves
- Mouth, nose and eye protection
- Gown
- Patient care equipment
- Environmental control
- Linen
- Occupational health and blood-borne
pathogens - Patient placement
- Respiratory hygiene/cough etiquette
used in the laboratory includes
gloves, fluid-resistant gowns, eye and face
shields, and Plexiglas countertop shields.
Personal protective equipment
should be worn when in contact
with patients, specimens, and laboratory
equipment or fixtures.
Gloves
is not a substitute for
hand hygiene, and hands must be
sanitized after gloves are removed.
Wearing gloves
includes both
hand washing and using
alcohol based antiseptic
cleansers.
Hand hygiene
has
developed hand
washing guidelines to
be followed for correct
hand washing.
Center for disease control and prevention
All biologic waste, except _________, must be
placed in appropriate containers labeled with
the biohazard symbol.
urine
may be discarded by pouring it into a
laboratory sink under a Plexiglas countertop
shield.
Urine
_______ must be taken to avoid splashing, and
the sink should be flushed with water after
specimens are discarded.
Care
Disinfection of the sink using a______ or _______
dilution of sodium hypochlorite should be
performed daily.
1:5 or 1:10 of sodium hypochlorite
Empty urine containers can be discarded as
____________________.
non-biologically hazardous waste
Hazard that All sharp objects must be
disposed in puncture-
resistant, leak-proof container
with the biohazard symbol.
Sharp hazard
Sharp Hazard that All sharp objects must be
disposed in ___________,______________,_____________
puncture-
resistant, leak-proof container
with the biohazard symbol.
Hazardous chemicals should be labeled
with a description of their particular
hazard, such as _______,_______,________,_______,_________,________
poisonous, corrosive,
flammable, explosive, teratogenic, or
carcinogenic.
When skin contact occurs, the best first aid
is to flush the area with large amounts of
water for at least ___________, then seek
medical attention.
15 minutes
Information contained in an MSDS includes the
following:
- Physical and chemical characteristics
- Fire and explosion potential
- Reactivity potential
- Health hazards and emergency first aid
procedures - Methods for safe handling and disposal
- Primary routes of entry
- Exposure limits and carcinogenic potential
It refers to the overall process of quality patient care and is regulated
throughout the total testing system.
Quality assessment
refers to all of the laboratory’s policies, processes,
procedures, and resources needed to achieve quality testing.
Quality system
In a clinical laboratory, a quality assessment program includes not only
testing controls, referred to as
Quality control
Under of Preexamination variables
specimen collection, handling, and storage
Under Examination variables
reagent and test performance, instrument
calibration and maintenance, personnel requirements, and technical
competence
Under Postexamination variables
reporting of results and interpretation
Quality Assessment Program:
• Procedure manuals
• Internal quality control
• External quality control
• Electronic quality control
• Calibration or calibration
verification
• Standardization
• Proficiency testing or External
quality assessment (EQA),
• Record keeping
• Equipment maintenance and
safety programs
• Training, education and
competency assessment of
personnel
• Scheduled and documented
review process.
A procedure manual containing all
the procedures performed in the
urinalysis section must be available
for reference in the working area
and must comply with the CLSI
guidelines.
Urinalysis produce manual
refers to the materials, procedures, and techniques
that monitor the accuracy, precision, and reliability of a
laboratory test.
Quality control
to ensure that acceptable standards are met during the process
of patient testing
Quality control
Quality control refers to the materials, procedures, and techniques
that monitor the ________,___________,__________of a
laboratory test
accuracy, precision, and reliability
to verify the accuracy and precision of a test and are exposed to the same conditions as
the patient samples.
External Quality Control
is the ability to maintain both precision and accuracy.
Reliability
consists of internal monitoring systems built in to the test system and are called internal or procedural
controls.
Internal quality control
Internal controls monitor the sufficient addition of a patient specimen or reagent, the
instruments/reagents interaction, and, for lateral flow test methods, whether the sample migrated
through the test strip properly.
Internal quality control
External quality control (EQC) uses a mechanical or electrical device in place of a liquid QC
specimen.
Electronic control
verifies the functional ability of a testing device
EQC
is the testing of unknown samples received from an outside agency, and
provides unbiased validation of the quality of patient test results.
Proficiency testing
mandates comparison
testing for laboratory accreditation.
Clinical laboratory improvement amendment
processes that affect the reporting of results and correct
interpretation of data.
Post examination variable
- Standardized reporting formats
- A written procedure for reporting, reviewing, and correcting errors must be
present. - Electronic transmission
Reporting result
Errors may be discovered in the laboratory through a QA procedure known as the
Delta checking
provides the guidelines for writing these procedures and policies.
