    Good fingerstick technique includes all except:

    • Obtaining a free flowing drop of blood

    • Wiping the first drop of blood off the finger

    • Cleaning the finger well with alcohol

    • Allowing air bubbles into the capillary tube

    Correct Answer
    A. Allowing air bubbles into the capillary tube
    Explanation
    Good fingerstick technique involves obtaining a free flowing drop of blood, wiping the first drop of blood off the finger, and cleaning the finger well with alcohol. Allowing air bubbles into the capillary tube is not a part of good fingerstick technique as it can interfere with the accuracy of the blood sample and may cause inaccurate results. Air bubbles can affect the volume of blood in the capillary tube, leading to incorrect measurements. Therefore, it is important to avoid introducing air bubbles into the capillary tube during the fingerstick procedure.

    After the blood has been dispensed into the sample well of the cassette, place the cassette in the drawer and press RUN:

    • Fter 5 minutes

    • Immediately

    • After 1 minute

    • Any time

    Correct Answer
    A. Immediately
    Explanation
    The correct answer is "Immediately" because the sentence states that after the blood has been dispensed into the sample well of the cassette, the next step is to place the cassette in the drawer and press RUN. Therefore, there is no waiting time mentioned in the sentence, indicating that the action should be done without delay.

    Quality Control should be run to:

    • Use cassettes

    • Check the pipette function

    • Comply with state requirements

    • Verify that the system is functioning properly

    Correct Answer
    A. Verify that the system is functioning properly
    Explanation
    Quality control is a process that ensures the system or product meets the required standards. In this case, running quality control helps to verify that the system is functioning properly. It ensures that all components and functions of the system are working as intended, identifying any potential issues or errors. By conducting quality control, any problems can be addressed and resolved, ensuring the system's reliability and accuracy. The other options mentioned, such as using cassettes, checking pipette function, and complying with state requirements, may be part of the quality control process, but ultimately the main purpose is to verify the system's proper functioning.

    The DATA button:

    • Opens the cassette drawer

    • Allows the user to view the last reported results

    • Closes the cassette drawer at the end of a test

    • Allows you to enter the configuration menu

    Correct Answer
    A. Allows the user to view the last reported results
    Explanation
    The DATA button allows the user to view the last reported results. This means that when the user presses the DATA button, they will be able to access and review the most recent test results. It provides a convenient way for the user to retrieve and analyze the data from previous tests.

     Before testing, the cassette should warm up, unopened, at room temperature for:

    • 5 minutes

    • 10 minutes

    • 15 minutes

    • 20 minutes

    Correct Answer
    A. 10 minutes
    Explanation
    Before testing, the cassette should warm up, unopened, at room temperature for 10 minutes. This is because allowing the cassette to warm up helps to ensure accurate and reliable test results. The warming up process allows the cassette to reach the same temperature as the testing environment, reducing the potential for temperature variations to affect the test outcome. Waiting for 10 minutes provides enough time for the cassette to equilibrate with the room temperature, ensuring optimal testing conditions.

    Before removing the replaceable ROM pack:

    • Disconnect the analyzer from the power source

    • Push the RUN button

    • Run the optics check cassette

    • Remove the metal clip

    Correct Answer
    A. Disconnect the analyzer from the power source
    Explanation
    It is important to disconnect the analyzer from the power source before removing the replaceable ROM pack to ensure safety and prevent any damage to the equipment. Removing the power source reduces the risk of electrical shock and allows for a safe removal of the ROM pack.

    To place the quality control sample into the cassette:

    • Use a capillary tube and plunger

    • Draw the control sample into a syringe

    • Use a Cholestech Mini-Pet™ and pipette tips

    • Drop an eyedropper of sample onto the cassette

    Correct Answer
    A. Use a Cholestech Mini-Pet™ and pipette tips
    Explanation
    The correct answer suggests using a Cholestech Mini-Pet™ and pipette tips to place the quality control sample into the cassette. This implies that the Cholestech Mini-Pet™ and pipette tips are the appropriate tools for accurately and precisely transferring the control sample into the cassette.

    Sample type "Whole B." should be used for all the following except:

    • Fingerstick samples

    • Quality control samples

    • Venous whole blood samples

    • Serum samples

    Correct Answer
    A. Serum samples
    Explanation
    Serum samples should not be tested using the "Whole B." type. The "Whole B." type is typically used for fingerstick samples, quality control samples, and venous whole blood samples. Serum samples are obtained by allowing the blood to clot and then removing the clot and the blood cells, leaving only the liquid portion (serum). This liquid portion is then used for testing. Therefore, serum samples should be tested using a different type of sample, not the "Whole B." type.

    If an optics check reading is outside the range:

    • The analyzer will not function

    • It is OK to run patient samples

    • Do not record the results on the optics check log

    • Run the quality control material

    Correct Answer
    A. The analyzer will not function
    Explanation
    If an optics check reading is outside the range, it indicates that there is an issue with the analyzer. This means that the analyzer will not function properly and may not provide accurate results. Therefore, it is not advisable to run patient samples or record the results on the optics check log. Instead, it is recommended to run the quality control material to ensure the accuracy and reliability of the analyzer.

    The sample in the capillary tube should be dispensed into the cassette in:

    • Less than 5 minutes

    • Less than 3 minutes

    • Immediately

    • Less than 10 minutes

    Correct Answer
    A. Less than 5 minutes
    Explanation
    The sample in the capillary tube should be dispensed into the cassette in less than 5 minutes because after a certain amount of time, the sample may start to degrade or undergo changes that could affect the accuracy of the test results. It is important to transfer the sample as quickly as possible to ensure the most reliable and accurate results.

    To perform a CHD Risk assessment, do all except:

    • Select Risk = CHD Risk in the configuration menu

    • Run a cassette with total cholesterol and HDL cholesterol

    • Push the DATA button twice after the results appear on the screen

    • Run a TC•GLU cassette

    Correct Answer
    A. Select Risk = CHD Risk in the configuration menu
    Explanation
    To perform a CHD Risk assessment, one should select "Risk = CHD Risk" in the configuration menu. This step is necessary to set up the device for assessing the risk. Running a cassette with total cholesterol and HDL cholesterol is also required as it provides the necessary data for the assessment. Pushing the DATA button twice after the results appear on the screen is not mentioned as a step in the process. Running a TC•GLU cassette is not mentioned as a step either, so it is not necessary for the CHD Risk assessment.
