been recently revised

A

Review of the procedure by a designated authority
has not been documented

36
Q

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

A

Instructions and training are not being provided to
personnel performing collections

37
Q

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

A safety statement about the heat produced by the
reaction is not in the procedure manual

38
Q

State a possible reason for an accreditation team to
report a deficiency in the following situations:

Open control bottles in the refrigerator are examined

A

The bottles have not been dated and initialled

39
Q

Explain whether you would accept them or take corrective action:

You are told that the supervisor always performs
the CAP proficiency survey

A

Correct; proficiency survey tests should be rotated
among personnel performing the tests

40
Q

Explain whether you would accept them or take corrective action:

QC is not performed daily on the reagent strips

A

Accept; QC on the Clinitest tablets must only be
performed when they are used to perform a test

41
Q

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

A

Correct; documentation of technical competency
should be performed on all personnel working in the
section and educational qualifications assessed

42
Q

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?

A

Delay in testing the specimen

43
Q

42 (a)

Where would the information concerning what
should have been done with this specimen be
found and the criteria for rejection?

A

Incident report

44
Q

42 (b)

What QA procedure may have detected this error?

A

Delta check

45
Q

42 (c)

How might this affect this patient’s care?

A

Treatment of the patient will be delayed because the
specimen will need to be recollected and tested. Extra
expense incurred

Q

42 (d)

How will the corrected results be documented?

A

Errors should be corrected as soon as possible following the institution’s policy. The original result must
