    The endoscope that provides a view of the middle of the thorax, between the two pleural sacs is

    • Bronchoscope

    • Laryngoscope

    • Thoracoscope

    • Mediastinoscope

    Correct Answer
    A. Mediastinoscope
    Explanation
    A mediastinoscope is an endoscope that is specifically designed to provide a view of the middle of the thorax, between the two pleural sacs. It is used to examine the mediastinum, which is the space between the lungs that contains the heart, esophagus, and other important structures. This procedure, known as mediastinoscopy, is often performed to diagnose and stage lung cancer, as well as to evaluate other conditions affecting the mediastinum. The other options, bronchoscope, laryngoscope, and thoracoscope, are also types of endoscopes, but they are not specifically designed for viewing the middle of the thorax.

    Which procedure is inappropriate when caring for optic lenses?

    • Blood, water, and irrigating solutions are removed with cotton tipped applicators and distilled water

    • Lens is always cleaned in a circular motion, beginning at the center

    • Oil or fingerprints are removed by soaking in solvent for 10 minutes adn drying with a cotton ball

    • Lint or dust are removed with a lens brush or rubber bulb syringe

    Correct Answer
    A. Oil or fingerprints are removed by soaking in solvent for 10 minutes adn drying with a cotton ball
    Explanation
    The procedure described in the answer is inappropriate because soaking the lens in solvent for 10 minutes can damage the lens and the use of a cotton ball for drying can leave lint or fibers on the lens surface. It is important to avoid using solvents on optic lenses as they can cause damage. Instead, a specialized lens cleaning solution should be used to clean oil or fingerprints, followed by gentle drying with a lens cleaning cloth or tissue specifically designed for lens cleaning.

    Which factor is not accomplished by chest drainage?

    • Drains fluid and air from pleural cavity

    • Provides water seal for gravity drainage

    • Suction controlled by level of water

    • Positive pressure re-establishment

    Correct Answer
    A. Positive pressure re-establishment
    Explanation
    Chest drainage accomplishes several factors, such as draining fluid and air from the pleural cavity, providing a water seal for gravity drainage, and controlling suction through the level of water. However, it does not involve the re-establishment of positive pressure.

    Chest rolls (bolsters)

    • Secure position

    • Minimize pressure on abdominal organs

    • Facilitate respiration

    • Minimize pressure on bony prominences

    Correct Answer
    A. Facilitate respiration
    Explanation
    Chest rolls or bolsters are used to facilitate respiration. By positioning the chest rolls correctly, it helps to open up the chest and allows for better expansion of the lungs during breathing. This can be particularly beneficial for individuals who have limited lung capacity or difficulty breathing. By providing support and allowing for easier breathing, chest rolls can help improve respiratory function and overall comfort during activities such as lying down or sitting.

    The following statements regarding lasers are true EXCEPT

    • Laser unit is protected from bumping against walls during movement

    • Flammable materials should not be used near laser impact site

    • Water or other solutions should not be placed on laser unit

    • Laser unit is in "on" position during entire case

    Correct Answer
    A. Laser unit is in "on" position during entire case
    Explanation
    The given answer states that the laser unit is in the "on" position during the entire case. However, this statement is not true because it is important to turn off the laser unit when it is not in use or when it is being transported to prevent any accidental exposure or damage.

    Which case would require the use of cottonoid strips?

    • Laminectomy

    • Tonsillectomy

    • Thorocotomy

    • Aortic aneurysmectomy

    Correct Answer
    A. Laminectomy
    Explanation
    Cottonoid strips are small pieces of absorbent material that are used in surgical procedures to control bleeding and protect delicate tissues. In a laminectomy, which is a surgical procedure to remove a portion of the vertebral bone, cottonoid strips may be used to absorb any blood or fluids that may accumulate during the surgery. They can also be used to provide a barrier between the surgical site and surrounding tissues, preventing any damage or contamination. Therefore, a laminectomy would require the use of cottonoid strips.

    Care of the microscope would include all of the following EXCEPT

    • Damp dust external surfaces with detergent-disinfectant before use

    • Damp dust lenses with detergent-disinfectant before use

    • Enclose in an antistatic plastic cover when not in use

    • Clean caster before each use

    Correct Answer
    A. Damp dust lenses with detergent-disinfectant before use
    Explanation
    The correct answer is "damp dust lenses with detergent-disinfectant before use." This is because using a detergent-disinfectant on the lenses of a microscope can damage them and affect their performance. Instead, lenses should be cleaned using a specialized lens cleaning solution or lens tissue to avoid any potential damage.

    The binocular microscope provieds stereoscopic vision. This refers to

    • The view afforded double eyepieces

    • The color projected on the field

    • The magnification capability

    • The illumination process

    Correct Answer
    A. The view afforded double eyepieces
    Explanation
    The binocular microscope provides stereoscopic vision because it has double eyepieces, allowing the viewer to see the specimen from two slightly different angles. This creates a three-dimensional image, giving a sense of depth and allowing for better perception of the specimen's structure and details. The other options, such as color projection, magnification capability, and illumination process, are not directly related to the concept of stereoscopic vision.
