1. Which action by the phleobotomist will comply with the CAP Safety Goal "To improve
patient and sample identification at the time of specimen collection" and the Joint Commission
Patient Safety Goal "To imrprove the accuracy
of patient identification"?: match the name and medical record number on the patients ID bracelet
to the name and medical record number on the preprinted collection label
2. A swab and requisition are received in the microbiology laboratory. The laboratory receiving
clerk notes a discrepancy between the patient identifiers on the requisition and the specimen
label, and questions the emergency department nurse MB. This is the 4th specimen this week that
has had a spec- imen discrepancy. What action is the most appropriate to prevent this type of
error in the future?: document error and communicate to laboratory supervisor so that the risk
manager conducts a root cause analysis
3. Preanalytical variables in laboratory testing include?: specimen acceptability
4. The first procedure to be followed if the blood gas instrument is out of control for all
parameters is?: recalibrate, the repeat control
5. Shown above is a Levy-Jennings quality control chart, which represent control values for 13
consecutive analyses for a particular serum constituent. If the 14th value is below the -2SD limit,
which of the following should be done?: analysis system should be checked for deteriorating
component
6. The mean value of a series of hemoglobin controls was found to be 15.2g/dL, and the standard
, MLT Laboratory Operations BOC
deviation was calculated at 0.20. Acceptable control range for the laboratory is + or - 2 standard
deviations. Which of the following represents the allowable limits for the control?: 14.8-15.6g/dL
7. Upon completion of a run of cholesterol tests, the technician recognizes that the controls are
not within the 2 standard deviations confidence range. What is the appropriate course of
action?: run a new set of controls and repeat specimens
8. The following data were calculated on a series of 30 determinations of serum uric acid control:
mean = 5.8mg/dL, 1 standard deviation = 0.15mg/dL. If confidence limits are set at + or - 2
standard deviations, which if the following represents the allowable limits for the control?: 5.50-
6.10mg/dL
9. An index of precision is statistically known as the?: coefficient of variation
10. The term used to describe reproductability is?: precision
11. The ability of a procedure to measure only the component(s) it claims to measure is called?:
specificity
12.The extent to which measurements agree with the true value of the quantity being measured is
known as?: accuracy
, MLT Laboratory Operations BOC
13. Diagnostic specificity is defined as the percentage of individuals?: without a given disease who
have a negative result by a given test
14. Employees are guaranteed the right to engage in self-organization and collective bargaining
through representatives of their choice or to refrain from these activities by which of the
following?: National Labor Relations Act
15. Which of the following organizations was formed to encourage the volun- tary attainment of
uniformly high standards in institutional medical care?: The Joint Commission(JCAHO)
16. The process by which an agency or organization uses predetermined standards to evaluate
and recognize a program of study in an institution is called?: accreditation
17. CLIA was established to provide oversight to?: any lab performing patient testing
18. CAP requires refrigerator temperatures to be recorded?: daily
19. A paper or electronic report of lab results must contain?: the name and address of the
testing laboratory
20. HIPAA is a federal law that requires?: confidentiality of patients health care information
between 2 organizations
21. Your friend calls and asks you to access his test results. Which of the following does this
violate?: HIPAA
22. A technician is asked to clean out the chemical reagent storeroom and discard and reagents
no used in the past 5 years. How should the technician proceed?: consult MSDS sheets for proper
