pulmonary pleura

hilar pleura

13

The condition in which blood fills the potential space between the layers of pleura is called:

16

A narrow thorax that is shallow from the front to back but very long in the vertical dimension is characteristic of what body habitus

18

What is the name of the special immobilization device used for pediatric chest studies

Pigg-O-Stat

19

What exposure is recommended for a chest study of a young pediatric patient

70-85 kV, short exposure time

20

Which of the following is NOT a valid reason to perform chest projections with the patient in the erect position:

To reduce patient dose

To demonstrate the air and fluid levels

To allow the diaphragm to move down farther

To prevent hyperemia of pulmonary vessels

To reduce patient dose

21

Why are the shoulders rolled forward or a PA projection of the chest

to remove scapulae from the lung fields

22

Where is the CR placed for an AP supine projection of the chest

3-4 inches below jugular notch

23

What term is defined as "shortness of breath"

dyspnea

24

A condition in which all or part of the lung is collapsed

atelectasis

25

A condition in which fluid builds in the lungs as a result of obstruction of the pulmonary circulation is termed

Which of the following is NOT a form of occupational lung disease

asbestosis

silicosis

anthracosis

tuberculosis

tuberculosis

28

manual exposure factors for a patient with a large pneumothorax should

be reduced

29

A PA chest radiograph reveals that the left sternoclavicular joint is superimposed over the spine (in comparison with the right joint) What specific positioning error is involved

rotation into the left anterior oblique (LAO) position

30

A PA chest radiograph demonstrates 10 posterior ribs above the diaphragm is this an acceptable degree of inspiration?

yes

31

A PA and lateral chest radiograph study is completed. The PA projection reveals the right costophrenic angle was collimated off, but both angles are included on the lateral projection. Would you repeat the PA projection?

yes

32

A lateral chest radiograph demonstrates the soft tissue of the upper limbs is superimposed over the apices of the lungs. How can this situation be prevented?

Raise upper limbs higher

33

A lateral chest radiograph reveals that the posterior ribs and costophrenic angles are separated by approximately 1/2 inch (slightly less than1 cm). Should the technologist repeat this projection.

No

34

A radiograph of an AP lordotic projection reveals the clavicles are projected within the apices. The clinical coordinator informs the student technologist that the study is unacceptable, but during the repeat exposure the patient complains of being too unsteady to lean backward for another projection. what other options are available if the student wants to complete the study?

perform an AP semiaxial projection

35

An ambulatory patient with a clinical history of advanced emphysema enters the emergency room. the patient is having difficulty breathing and is receiving oxygen. The physician has ordered a PA and lateral chest study. Should the technologist alter the typical exposure factors for this patient?

Yes, decrease exposure factors

36

A patient enters the ER with an injury to the chest. The ER physician suspects a pneumothorax may be present in the right lung. The patient is unable to stand or sit erect. Which specific position/projection can be performed to confirm the presence of pneumothorax?

left lateral decubitus

37

A PA and lateral chest study reveals a suspicious mass located near the heart in the right lung. The radiologist would like a radiograph of the patient in an anterior oblique position to delineate the mass from the heart. which position or projection should the technologist use to accomplish this objective?

60 degree LAO

38

A patient with a history of pulmonary edema comes to the radiology department and is unable to stand. The physician suspects fluid in the left lung. Which specific projection should be used to confirm this diagnosis?

left lateral decubitus
