1. Topographic landmarks used to position for chest radiography include the:
    1) Iliac crest
    2)Jugular notch
    3)Vertebra prominens
    2 & 3
  2. Which consideration must be met for any decubitus chest projections?
    The CR must be horizontal and parallel to the floor.
  3. What is the optimal amount of time a patient should lie on their side prior to a left lateral decubitus projection for the abdomen?
    10 to 20 minutes
  4. An abnormal accumulation of fluid in the pleural cavity is termed:
    Pleural effusion
  5. Which projection is performed to demonstrate free air or gas in the abdominal cavity when the patient is unable to stand?
    Left lateral decubitus
  6. Supine abdomen projections should be exposed on:
  7. Where is the CR directed for a supine AP projection of the abdomen?
    Iliac crest
  8. Voluntary motion can
    1. result from patient breathing.
    2. be controlled by using a short exposure time
    3. result from peristaltic activity.4. be identified as sharp bony cortices and blurry gastric and intestinal gases.

  9. On inhalation the lungs expand:
    1. vertically.
    2. transversely.
    3. anteroposteriorly.

  10. For a PA chest projection with accurate positioning, the 
    1. SID is set at 72 inches (183 cm).
    2. shoulders are positioned at equal distances from the IR.
    3. upper midcoronal plane is tilted slightly toward the IR.4. elbows and shoulders are rotated posteriorly
    1 and 2 only
  11. For an upright AP abdomen projection, the
    1. CR is 2 inches above iliac crest
    2. patient remains in an upright position at least 5 to preferably 20 minutes before the image is obtained.
    3. symphysis pubis should be included.
    4. patient is instructed to take a deep inspiration before the image is obtained.

  12. What is the reason this lateral chest radiograph is unacceptable?Image Upload 1
    The patient's right side was rotated posteriorly.
  13. Accumulation of air in the pleura cavity is known as:
  14. Characteristics of a properly positioned PA projection of the chest include:Chin above the chestClavicles above the apicesSternal ends of the clavicles equidistant from midline
    1 and 3 only
  15. This PA Chest is a repeatable error because the patient wasImage Upload 2
    Leaning away from the IR
  16. In what position is this patient?Image Upload 3
    Trendelenburg position
  17. The CR and IR are lowered at least 1 inch from the PA for the lateral to prevent cutoff of costophrenic angles because of
    divergence of the beam
  18. This PA chest projection radiograph reveals that the sternoclavicular joints (clavicle heads) are not equal distance from the spine. What specific positioning correction is required?Image Upload 4
    Have patient rotate left shoulder closer to the IR
  19. The structures within the lung where oxygen and carbon dioxide gas exchange occurs are called:
  20. What is indicated by the arrows?Image Upload 5
    psoas muscles
  21. What is the minimum amount of time a patient must remain in the decubitus position for a chest x-ray prior to exposure?AnswerSelected Answer:
  22. Why is it important to perform the PA projection rather than the AP for a routine chest study?
    PA position will reduce heart magnification.
  23. What is the primary imaging correction needed?Image Upload 6
    Left side of patient needs to be moved (rotated) anteriorly.
  24. Which one of the following positioning considerations is most important in demonstrating air/fluid levels in the thorax during chest radiography?
    Patient in upright position
  25. Which one of the following positioning considerations is most important in removing the scapula from the field of view?
    Shoulders rolled forward
  26. Why is it important to perform an erect left lateral rather than the erect right lateral position as part of the routine chest study?
    Reduces magnification of the heart
  27. What is the recommended kV range for an abdomen projection?
    70 to 80 kV
