A possible physical hazard in the hospital is:
Running to answer the telephone
Quality assessment refers to:
Quality of specimens and patient care
During laboratory accreditation inspections, procedure manuals are examined for the presence of:
Critical values
Procedure references
Procedures for specimen preservation
All of the above
All of the above
As supervisor of the urinalysis laboratory, you have just adopted a new procedure. You should:
Put a complete, referenced procedure in the manual
Indicate whether each of the following would be considered at what phase:
Reagent expiration date
Rejecting a contaminated specimen
Constructing a Levy-Jennings chart
Telephoning a positive Clinitest result on a
newborn
Calibrating the centrifuge
Collecting a timed urine specimen
Examination
Pre-examination
Examination
Post-examination
Examination
Pre-examination
The testing of sample from an outside agency and the comparison of results with participating laboratories is called?
Proficiency testing
A color change that indicates that a sufficient amount of
patient’s specimen or reagent is added correctly to the test system would be an example of:
Internal QC
What steps are taken when the results of reagent strip
QC are outside of the stated confidence limits?
Check the expiration date of the reagent strip
Run a new control
Open a new reagent strips container
All of the above
All of the above
When a new bottle of QC material is opened, what
information is placed on the label?
The date and the laboratory worker’s initials
When a control is run, what information is documented?
The lot number
Expiration date of the control
The test results
All of the above
All of the above
State a possible reason for an accreditation team to
report a deficiency in the following situations:
The urine microscopic reporting procedure has
been recently revised
Review of the procedure by a designated authority
has not been documented
State a possible reason for an accreditation team to
report a deficiency in the following situations:
An unusually high number of urine specimens are
being rejected because of improper collection
Instructions and training are not being provided to
personnel performing collections
State a possible reason for an accreditation team to
report a deficiency in the following situations:
A key statement is missing from the Clinitest
procedure
A safety statement about the heat produced by the
reaction is not in the procedure manual
State a possible reason for an accreditation team to
report a deficiency in the following situations:
Open control bottles in the refrigerator are examined
The bottles have not been dated and initialled
Explain whether you would accept them or take corrective action:
You are told that the supervisor always performs
the CAP proficiency survey
Correct; proficiency survey tests should be rotated
among personnel performing the tests
Explain whether you would accept them or take corrective action:
QC is not performed daily on the reagent strips
Accept; QC on the Clinitest tablets must only be
performed when they are used to perform a test
Explain whether you would accept them or take corrective action:
The urinalysis section is primarily staffed by
personnel assigned to other departments for whom
you have no personnel data
Correct; documentation of technical competency
should be performed on all personnel working in the
section and educational qualifications assessed
An outpatient urine specimen was delivered to the laboratory at 0800 and placed on the counter in the
Urinalysis department. The medical laboratory scientist
performed urinalysis on the specimen at 1130. The
following results were abnormal:
Clarity: Cloudy
pH: 9.0
Nitrite: Positive
The patient was a known diabetic; however, the
glucose result was negative
What could be a possible cause for the abnormal
results?
Delay in testing the specimen
42 (a)
Where would the information concerning what
should have been done with this specimen be
found and the criteria for rejection?
Incident report
42 (b)
What QA procedure may have detected this error?
Delta check
42 (c)
How might this affect this patient’s care?
Treatment of the patient will be delayed because the
specimen will need to be recollected and tested. Extra
expense incurred
42 (d)
How will the corrected results be documented?
Errors should be corrected as soon as possible following the institution’s policy. The original result must
not be erased
