    Why is the equipment used to take a blood sample sterile?

    • So that no blood gets on to the equipment

    • So that the nurse is protected against illnesses

    • So that no pathogens/bacteria are introduced into the body

    • So that no pathogens/bacteria gets onto the equipment

    Correct Answer
    A. So that no pathogens/bacteria are introduced into the body
    Explanation
    The equipment used to take a blood sample needs to be sterile to prevent the introduction of any pathogens or bacteria into the body. If the equipment is not sterile, it can contaminate the blood sample and potentially introduce harmful microorganisms into the patient's bloodstream. This can lead to infections or other complications. Therefore, ensuring the sterility of the equipment is crucial in maintaining the safety and health of the patient.

    Why must the blood film be very thin?

    • So that the glass slide can fit on top easily

    • So that the red blood cells can be distinguished from each other when under a miscroscope

    • So that the red blood cells don't hit each other and burst

    • So that no excess blood escapes from the glass slide

    Correct Answer
    A. So that the red blood cells can be distinguished from each other when under a miscroscope
    Explanation
    The blood film must be very thin so that the red blood cells can be easily distinguished from each other when viewed under a microscope. If the blood film is too thick, the red blood cells may overlap or cluster together, making it difficult to accurately observe and analyze them. A thin blood film allows for better visualization and identification of individual red blood cells, which is crucial for diagnosing and monitoring various blood disorders and conditions.

    Why is a stain used?

    • So that the blood cells don't burst

    • So that the blood cells stay on the slide and do not slip

    • So that the blood cells become large enough to see

    • So that the blood cells become more visible

    Correct Answer
    A. So that the blood cells become more visible
    Explanation
    A stain is used to make blood cells more visible because they are typically transparent and difficult to see under a microscope. Staining involves adding a dye or chemical to the blood sample, which attaches to specific components of the cells and enhances their contrast. This allows for easier identification and examination of the blood cells under a microscope. Staining can also help differentiate between different types of blood cells and identify any abnormalities or diseases present.

    What substance do we use to fix the blood to the slide?

    Correct Answer
    alcohol
    methanol
    Explanation
    Alcohol and methanol are both commonly used substances to fix blood to a slide. These substances help preserve the blood sample and prevent degradation. They also aid in the staining process, allowing for better visualization of the blood cells under a microscope. Both alcohol and methanol have similar properties and can be used interchangeably in this context.

    Why must the slide be very clean and grease-free?

    • So that the blood cells can stick to the slide

    • So we can see the blood cells when looking under a microscope

    • So that the blood cells do not burst

    Correct Answer
    A. So that the blood cells can stick to the slide
    Explanation
    The slide must be very clean and grease-free so that the blood cells can stick to it. This is important because if the slide is dirty or greasy, the blood cells may not adhere properly, leading to inaccurate observations under the microscope. Having a clean and grease-free slide ensures that the blood cells are properly immobilized and can be easily observed and studied.

    Why is blood taken from a vein and not an artery? (4 answers)

    • Veins are thinner

    • Veins are wider

    • Veins are nearer the surface

    • Arteries have thinner walls, so it is harder to insert a needle

    • Veins have thinner walls, so it is easier to insert a needle

    • The blood from an artery has too high a blood pressure

    Correct Answer(s)
    A. Veins are wider
    A. Veins are nearer the surface
    A. Veins have thinner walls, so it is easier to insert a needle
    A. The blood from an artery has too high a blood pressure
    Explanation
    Blood is taken from a vein and not an artery because veins are wider, nearer the surface, and have thinner walls, making it easier to insert a needle. Additionally, the blood from an artery has too high a blood pressure, which can make it more difficult to collect a sample.
