  • 2. 

    Collimate on four sides to area of lung fields border of illuminated fields should be to level of vertebra prominens  and lateral border to outer skin margins. describes which of the following?

    • Patient position

    • Part position

    • Central ray

    • Collimation

    • Respiration

    Correct Answer
    A. Collimation
    Explanation
    The given statement describes collimation. It explains that the collimation should be done on all four sides to the area of lung fields. The border of the illuminated fields should be at the level of the vertebra prominens and the lateral border should be to the outer skin margins. This indicates the proper technique for adjusting the collimation in order to capture the desired area of the lung fields in the radiographic image.

    What is the correct IR size for this position?

    • 8"x10"

    • 10"x12"

    • 11"x14"

    • 14"x17"

    Correct Answer
    A. 14"x17"
    Explanation
    The correct IR size for this position is 14"x17". This size is commonly used in medical imaging, such as X-rays, as it provides a larger surface area to capture detailed images of the body. The larger size allows for better visualization and analysis of the images, which is especially important in diagnosing and treating medical conditions accurately.

    • cr prependicular to IR and centered to midsagittal plane at leve T7
    • IR centered to CR
    • SID of 72 inches
    describes which of the following?

    • Patient position

    • Part position

    • Central ray

    • Collimation

    • Respiration

    Correct Answer
    A. Central ray
    Explanation
    The given information describes the central ray. It states that the central ray is perpendicular to the image receptor (IR) and centered to the midsagittal plane at the level of T7. It also mentions that the IR is centered to the central ray. Additionally, it provides the source-to-image distance (SID) of 72 inches, which is relevant to the central ray.

    • patient errect, feet spread slightly  wieght equally distributed on both feet
    • chin raised and resting against IR
    • hands lower hips palm out elbows partially flexed
    • shoulders rotated fowrad against ir to allow scapula to move clear of lung fields
    describes which of the following?

    • Patient position

    • Part position

    • Central ray

    • Collimation

    • Respiration

    Correct Answer
    A. Patient position
    Explanation
    The given description describes the patient position. It provides details about how the patient should be positioned, including the posture of the body, the position of the chin, hands, and shoulders. This information is important for ensuring that the patient is in the correct position for the procedure.

  • 6. 

    In both stretcher and erect there can be no rotation of the thorax

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Both stretcher and erect positions refer to the body being in a straight and upright position. In both cases, the thorax, which is the chest area, remains fixed and does not rotate. Therefore, the statement is true.

    Rate this question:

  • 7. 

    When a patient is Hypersthenic what position should the IR be placed

    Correct Answer
    crosswise
    Explanation
    When a patient is hypersthenic, the IR (image receptor) should be placed crosswise. This means that the IR should be positioned perpendicular to the long axis of the patient's body. This positioning allows for better visualization and imaging of the patient's anatomy, ensuring that the images captured are accurate and clear.

    Shielding for patients shouldn't  be around the waist for this position

    • True

  • 9. 

    Should the radiograph appear similar to an ambulatory PA chest ?

    • Yes

    • No

    Correct Answer
    A. Yes
    Explanation
    The radiograph should appear similar to an ambulatory PA chest because an ambulatory PA chest radiograph is a standard imaging technique used to visualize the lungs and other structures in the chest. It is taken while the patient is standing upright and provides a clear view of the lungs, heart, and other structures. Therefore, if the radiograph appears similar to an ambulatory PA chest, it indicates that the imaging technique was performed correctly and the structures in the chest are visualized accurately.

    What is the standard mAs for this position?

    Correct Answer
    3
    Explanation
    The standard mAs for this position is 3.

    Should a seated PT have thier arms around a cassette unless a chest ir device is used ?

    • Yes

    • No

    • Sometimes

    Correct Answer
    A. Yes
    Explanation
    A seated PT (patient) should have their arms around a cassette unless a chest X-ray device is used. This is because when a patient is seated, their arms provide support and stability, which helps to minimize any movement during the X-ray procedure. However, if a chest X-ray is being performed, the patient's arms should be positioned away from the cassette to ensure a clear and accurate image of the chest area.

    describes which of the following?

    • Patient position

    • Part position

    • Central ray

    • Collimation

    • Respiration

    Correct Answer
    A. Part position
    Explanation
    The given instructions describe the part position. It states to align the midsagittal plane with the central ray and the midline of the image receptor, with equal margins between the lateral thorax and the sides of the image receptor. It also mentions ensuring no rotation of the thorax and raising or lowering the central ray and image receptor as needed to the level of T7 or the average patient. These instructions specifically pertain to positioning the part (thorax) correctly for the radiographic examination.
