      4. the patient
    2. Which of the following information concerning a specific patient is entered into the LIS?
      1. specific test request
      2. specimen collection time
      3. patient demographics
      4. laboratory data.
    3. Which of the following describes the function(s) of the LIS?
      1. collection of patient information
      2. generation of specimen test results
      3. assembling of data output
      4. producing ancillary reports
    4. The term “interfacing” refers to which of the following?
      1. the display of computer-generated information.
      2. the degree of effort that the system makes to be accurate.
      3. the information of a video screen device.
      4. the exchange of information between the computer and operator.
    5. The technologist usually interfaces with the LIS to accomplish the following:
      1. obtain billing information
      2. enter patient test data
      3. obtain inventory data
      4. verify patient data
    6. The software of the LIS is usually:
      1. easily changed
      2. purchased from a commercial supplier
      3. available from help
      4. a complex series of instructions
    7. Patient identification in a LIS may be accomplished in the following way(s):
      1. hospital patient number
      2. social security number
      3. encounter number
      4. billing number
    8. What function(s) is (are) provided by an laboratory information system?
      1. Results reporting
      2. Specimen tracking
      3. Phlebotomy labels
      4. Management reports
    9. Which of the following would not make a satisfactory LIS specimen number?
      1. The patient medical record number (e.g., 123456 where 123456 is the patient’s medical record number).
      2. A number generated by the LIS starting from 1 and incrementing by 1 for each new specimen (e.g., 1, 2, 3 and so on).
      3. A number consisting of the year followed by the number of days past January 1st followed by the number of specimens received since midnight by the system (e.g., 20011801234 is the 1234th specimen received on the 180th day past January 1st in year 2001).
      4. A number started by an unique letter for the each day of the week followed by a serial number generated by the LIS (e.g., specimens on Monday start with M1, M2, M3, and so on).
      5. A number starting at 99999999 and decremented by 1 for each specimen received.
    10. What is the order of events occur between an LIS and a multichannel chemistry analyzer in a two-way instrument interface?
      1. Instrument transmits specimen number to LIS
      2. Instrument transmits analytical results to LIS
      3. LIS transmits test requests to instrument
      4. Bar code containing the specimen number is read by instrument
      5. Tech reviews results

      2. A totally robotic laboratory operating without humans.
      3. A laboratory travelling on wheels.
      4. Automation which eliminates much of the manual tasks associated with centrifugation, making aliquots, racking, pipetting, specimen storage, etc. and integrates different instruments.
      5. A computer controlled laboratory.
    13. If a laboratory has a situation where a patient’s privacy has violated, it most likely results from:
      1. A computer hacker coming through the Internet.
      2. An employee who does not understand the meaning of patient privacy.
      3. A newspaper reporter looking through trash.
