    The primary controlling factor of radiography contrast is:

    • MA

    • Time

    • KVp

    • SID

    Correct Answer
    A. KVp
    Explanation
    kVp, or kilovoltage peak, is the primary controlling factor of radiography contrast. It determines the energy level of the X-ray beam, which directly affects the penetration power and the ability to differentiate between different tissues. By adjusting the kVp, the radiographer can control the level of contrast in the image. Higher kVp values result in lower contrast images with a wider range of gray tones, while lower kVp values produce higher contrast images with a greater distinction between tissues. Therefore, kVp plays a crucial role in determining the overall contrast and quality of the radiographic image.

    "Oblique" positions are always named according to the side of the patient that is:

    • Closest to the x-ray tube

    • The source of pathology

    • Closest to the IR

    • Farthest from the IR

    Correct Answer
    A. Closest to the IR
    Explanation
    In radiology, "oblique" positions refer to the positioning of the patient's body in a tilted or angled manner. In this case, the correct answer is "closest to the IR." This means that the oblique position is named based on the side of the patient's body that is closest to the image receptor (IR), which is the device that captures the x-ray image. This naming convention helps to accurately describe the positioning of the patient and the direction of the x-ray beam in relation to the IR.

    Rate this question:

  • 18. 

    Why is it desirable to collimate to the area of interest?

    • Lengthens the scale of contrast

    • Reduces the required milliamperage

    • Reduces the amount of scatter radiation produced

    • Compensates for an increase in object-to-image receptor distance (OID)

    Correct Answer
    A. Reduces the amount of scatter radiation produced
    Explanation
    Collimating to the area of interest reduces the amount of scatter radiation produced. Scatter radiation is produced when the primary x-ray beam interacts with the patient's body and changes direction, leading to a decrease in image quality and an increase in radiation dose to the patient. By collimating to the area of interest, the x-ray beam is restricted to only pass through the specific region being imaged, minimizing the amount of scatter radiation that is generated. This helps to improve image quality and reduce radiation exposure for the patient.

    Where should the radiographer wear a TLD during fluoroscopic procedures?

    • Under the lead apron, at the level of the waist

    • Under the lead apron, at the level of the collar

    • Outside the lead apron, at the level of the waist

    • Outside the lead apron, at the level of the collar

    Correct Answer
    A. Outside the lead apron, at the level of the collar
    Explanation
    The radiographer should wear a TLD (thermoluminescent dosimeter) outside the lead apron, at the level of the collar. This is because the TLD is used to measure the radiation dose received by the radiographer, and wearing it outside the lead apron ensures that it accurately reflects the radiation exposure to the head and neck area, which is more critical than the waist area. Wearing it at the level of the collar allows for the most accurate measurement of radiation dose to these sensitive areas. Wearing it under the lead apron or at the level of the waist would not provide an accurate measurement.

    In which quadrant of the abdomen is the appendix located?

    • Right upper quadrant

    • Right lower quadrant

    • Left upper quadrant

    • Left lower quadrant

    Correct Answer
    A. Right lower quadrant
    Explanation
    The appendix is located in the right lower quadrant of the abdomen. This is a specific area in the lower right side of the abdomen, below the right ribcage and above the pelvis. The appendix is a small, finger-shaped pouch that is attached to the large intestine. It is important to know the location of the appendix as it is a common site for inflammation and infection, known as appendicitis.

    Which changed in exposure factors should be used to control voluntary motion that is a result of the patient's age or mental illness?

    • Increase the milliamperage

    • Decrease the milliamperage

    • Increase the exposure time

    • Decrease the exposure time

    Correct Answer
    A. Decrease the exposure time
    Explanation
    To control voluntary motion caused by the patient's age or mental illness, decreasing the exposure time should be used. By reducing the exposure time, the patient has less time to move, resulting in a clearer and sharper image. This adjustment compensates for the patient's inability to remain still during the procedure, ensuring a higher quality diagnostic image. Increasing the milliamperage would only increase the amount of radiation delivered, which is not necessary in this case.

    During fluoroscopy, the personnel monitor (radiation badge) should be worn:

    • Outside the apron - at the collar

    • Inside the apron - at the collar

    • Outside the apron - at the waist

    • Inside the apron - at the waist

    Correct Answer
    A. Outside the apron - at the collar
    Explanation
    The personnel monitor (radiation badge) should be worn outside the apron at the collar during fluoroscopy. This is because the collar area is closest to the radiation source and is therefore the most likely area to receive the highest dose of radiation. Wearing the badge outside the apron ensures that it accurately measures the radiation exposure to the personnel's body. Wearing it inside the apron or at the waist would not provide an accurate measurement of radiation exposure.

    Radiographers receive approximately how much radiation per year?

    • 50 mrad

    • 60 mrad

    • 50 rad

    • 70 rad

    Correct Answer
    A. 50 mrad
    Explanation
    Radiographers receive approximately 50 mrad of radiation per year. This is a relatively low dose of radiation that they are exposed to. It is important for radiographers to be aware of their radiation exposure and take necessary precautions to minimize any potential health risks. Regular monitoring and safety measures are implemented to ensure the safety of radiographers and patients during medical imaging procedures.

    When a pregnant patient must be examined, the examination should be done using which of the following?  1) precisely collimated beams 2) carefully positioned protective shields 3) use of a high kVp technique

    • 1 and 2

    • 1 and 3

    • 2 and 3

    • 1, 2, and 3

    Correct Answer
    A. 1, 2, and 3
    Explanation
    During pregnancy, it is important to minimize radiation exposure to the fetus. Precisely collimated beams help to focus the radiation only on the area of interest, reducing scatter radiation to the abdomen. Carefully positioned protective shields can be used to further shield the fetus from unnecessary radiation. Using a high kVp technique allows for better penetration of the x-rays, reducing the need for higher doses and therefore minimizing the radiation exposure to the fetus. Therefore, using all three options - precisely collimated beams, carefully positioned protective shields, and a high kVp technique - is recommended when examining a pregnant patient.

    Which of the following positioning terms indicates that the patient is "lying down" and the "central ray is horizontal" ?

    • Lateral

    • Decubitus

    • Recumbent

    • Mediolateral

    Correct Answer
    A. Decubitus
    Explanation
    The term "decubitus" refers to the position where the patient is lying down, typically on their side, with the central ray of the X-ray machine being horizontal. This position is commonly used in medical imaging to capture specific views of the body, such as the lungs or abdomen. The other options, lateral, recumbent, and mediolateral, do not specifically indicate the patient lying down or the horizontal central ray.
