    Use the following Key to answer Questions 1 - 3:

    1. 1, 2, and 3 are correct
    2. 1 and 3 are correct
    3. 2 and 4 are correct
    4. only 4 is correct
    5. all are correct
    1. Which of the following is a/are general characteristic(s) of discrete multichannel analyzers?
      1. each specimen is added into a separate compartment along with the reagents
      2. the absorbance of the reaction mixture is read at a steady-state plateau
      3. carryover between samples is minimized
      4. all of the tests done by the analyzer are performed on each specimen
    2. For random access analyzers, it is true that:
      1. all of the available tests done by the analyzer are performed on each specimen
      2. reagent and sample volumes are dependent upon the inner diameter of pump tubing
      3. the integrity of individual samples is maintained through the segmentation of the sample stream with air bubbles
      4. the analyses that are performed for a sample are only the ones that were ordered
    3. The dry—chemical reagent technique has the following features:
      1. the dry reagent is impregnated on a solid phase
      2. can be prepared by most laboratories using common reagents
      3. the measuring reaction begins when sample comes in contact with reagent
      4. usually cheaper than techniques
      5. using bulk reagents
    4. An instrument has 17 reagents available for analysis and can perform 3 tests at a time. The immediate test repertoire of this instrument is:
      1. 3
      2. 14
      3. 17
      4. 20
      5. 51
    5. Stat. Instruments should have high test throughput:
      1. true
      2. false
    6. An instrument can process 40 samples an hour and perform 6 tests on each sample simultaneously. The test throughput of this analyzer is:
      1. 6
      2. 40
      3. 46
      4. 240
      5. 280
    7. Which of the following is not usually considered to be a function of an automated analyzer?
      1. computation
      2. proportioning of reagent
      3. auto-verification
      4. incubation
      5. mixing

    Use the following Key to answer Questions 8 through 11:

    1. 1, 2, and 3 are correct
    2. 1 and 3 are correct
    3. 2 and 4 are correct
    4. only 4 is correct
    5. all are correct
    1. Automated Front-End specimen processing includes:
      1. specimen identification
      2. specimen sorting
      3. specimen decapping
      4. specimen aliquoting
    2. The goals of laboratory automation are:
      1. to reduce cost
      2. to decrease laboratory testing
      3. to reduce laboratory errors
      4. to increase workstations
    3. The major drawbacks of Total Laboratory Automation are:
      1. Substantial financial investment
      2. Inability to sort and decap specimens
      3. Limited availability of laboratory space
      4. Lack of clot and aliquot capabilities
    4. In some laboratories, manual Front-End Specimen Processing accounts for:
      1. Is needed for workstation consolidation
      2. 60% of the testing cost
      3. Is required for archiving of specimens
      4. Is responsible for most of the lost specimens
    5. Autoverification of laboratory results is the automated reporting of selected test results without verification by the technologist or laboratory supervisor.
      1. True
      2. False
    6. Archiving and retrieval of specimens is a time consuming process that can be automated using stand-alone systems.
      1. True
      2. False
