Already Graded A+
Pre-analytical variables in laboratory testing include - 🧠ANSWER
✔✔Specimen acceptability
Which of the following is not a potential source of post analytical errors
1) Excessive delay in reporting or retrieving a test result
2) Interpretation of results
3) Verbal notification of test results
4) Labeling the specimen at the nurses station - 🧠ANSWER ✔✔Labeling
the specimen at the nurses station
A pre-analytical error could be introduced by - 🧠ANSWER ✔✔Vigorously
shaking of blood tube to prevent clotting
,The most important diagnosis and therapeutic management decision tool
used to interpret test results is - 🧠ANSWER ✔✔Reference intervals
A clean catch urine is submitted to the laboratory for routine urinalysis and
culture. The routine urinalysis is done first, and three hours later, the
specimen is sent to the microbiology department for culture. The specimen
should - 🧠ANSWER ✔✔Be rejected due to the time delay
Urine sample should be examined within one hour avoiding because -
🧠ANSWER ✔✔Bacterial contamination will cause alkalinization of the urine
A urine specimen comes to laboratory seven hours after it is obtained. It is
acceptable for culture only if the specimen has been stored - 🧠ANSWER
✔✔At 4-7°C
Pre-analytical errors are major contributors to total laboratory errors.
Examples of obvious pre-analytical errors are - 🧠ANSWER ✔✔Specimen
collected in the wrong container
Unlabeled specimen
QNS, hemolyzed or lipemic specimens
,True or false analytical errors are not obvious to providers - 🧠ANSWER
✔✔True
Laboratory should monitor and track pre-analytical indicators of quality to
develop strategies to identify root causes of air and develop counter
measures. Examples of pre-analytical quality indicators include -
🧠ANSWER ✔✔Rate of an accurate test order entry into laboratory
information system
The first procedure to be followed if the blood gas instrument is out of
control for all parameters is - 🧠ANSWER ✔✔Recalibrate, then repeat
control
Upon completion of a run of cholesterol test, the technician recognizes that
the controls are not within the two standard deviations confidence range.
What is the appropriate course of action - 🧠ANSWER ✔✔Run a new set of
controls and repeat specimens
The following data were calculated on a series of 30 determinations of
serum uric acid control: mean = 5.8 mg/dL, 1 standard deviation = 0.15
mg/dL. If confidence limits are set at +/- 2 Standard deviations, which of the

, following represents the allowable limits for the control - 🧠ANSWER
✔✔5.50 to 6.10 mg/dL
What are the three steps of an individualized quality control plan (IQCP) -
🧠ANSWER ✔✔Risk assessment, quality control plan, quality assessment
A delta check is a method that - 🧠ANSWER ✔✔Monitors patient samples
day today
On Monday a patient's hemoglobin determination was 11.3 g/dL (113 g/L),
and on Tuesday it measured 11.8 g/dL (118 g/L). The standard deviation of
the method used is +/- 2 g/dL (2 g/L). Which of the following can be
concluded about the hemoglobin values given - 🧠ANSWER ✔✔There is no
significant change in the patient's hemoglobin concentration
A benefit of micro essays, such as point of care methods, include -
🧠ANSWER ✔✔Reduced sample volume
The use of security system such as firewalls and data encryption for
electronica transmission of patient data from a laboratory information
system to a remote location or required for - 🧠ANSWER ✔✔HIPAA
