A

T7

27

When performing a routine chest radiograph, why should the shoulders be rolled anteriorly?

A

To remove the scapular shadows from the lung field.

28

What body habitus would be a massive build with organs that are high, broad, and typically away from the mid-line?

A

Hypersthenic

Smell a flower-sniff in

31
Q

A

Mediastinum

32
Q

What anatomic structures are used to determine rotation of the PA or AP chest radiograph?

A

SC joints equidistant from vertebral column

33
Q

What anatomic structures are used to determine rotation of the lateral chest radiograph?

A

superimposition of the ribs posterior to the vertebral column

34
Q

If a filter was to be used on any Lateral Decubitus chest exam, where would the think end of the filter be placed and why?

A

This end is used on upper lung (air filled lung); evens out densities. It is easier to penetrate than fluid on side down.

35
Q

When the esophagus is filled with barium, how much should the patient be obliqued in order to demonstrate the great vessels?

A

55-60 degree

36
Q

AP or PA projection ( Rt or Lt Decub position)- A small amount of ____ in the pleural cavity is usually best shown with pt lying on affected side ( mediastinal shadows and fluid won’t overlap).

A

Fluid (looking for fluid)

37
Q

AP or PA projection (Rt or LF Decub position)- A small amount of free ____ in the pleural cavity is generally best demonstrates with the pt lying on the unaffected side.

A

Air (looking for air)

38
Q

AP or PA projection (Rt or Ft Decub position)- Allow pt to remain in position on their side for 1 minutes prior to exposure (best allows 2 to settle and free 3 to rise).

A

1) 5 minutes
2) water
3) air

39
Q

AP or PA projection (RT or LF Decub position)- Adjust IR 1 beyond shoulders. CR is 2 and 3 to center of IR and at 4 for AP or at 5 for PA. No Rotation (6).
7 side in its entirety; apices.

A

1) 1 1/2-2”
2) perpendicular
3) horizontal
4) a level 3” below the jugular notch (mid-sternum)
5) T7
6) clavicles equidistant from the spine
7) affected side

40
Q

Fluid is 1 on radiograph and air is 2.

A

1) white

2) black

41
Q

Lateral projection (Ventral or Dorsal Decub position)- Place IR to level of the 1 and CR should enter the 2 3-4” below 3 for dorsal decub and 4 for ventral decub.

2) kVp
3) sternum
4) cervical spine

Anterior Neck- Occupies region between skull and 1. The act of swallowing is called 2. Enlarged adenoids (aka 3 tonsils).

A

1) Thorax
2) deglutition
3) pharyngeal

45
Q

Pharynx/Larynx- 1 Projection is standard. Center IR and CR at level of or slightly below 2. Instiratory phase of quiet nasal breathing to ensure that nose and throat passages are 3 filled (breathe in through nose).

A

1) AP projection
2) Laryngeal Prominence (aka thyroid cartilage, adam’s apple, C4-C5)
3) air

46
Q

Lateral Projection (Rt or Lt)- 1 centered to midline of IR. CR can
a. Center IR 1” below the 2. (dem. nasopharynx and cleft palate studies).
b. Center IR at the level of 3 angles. (dem. orotharynx)
