Q

In order to properly position an AP humerus what action is performed with the hand?

A

Supination

17
Q

List the 2 breathing options for a transthoracic lateral humerus and why each is performed.

A
  1. Full inspiration to improve the contrast and decrease exposure necessary for penetration. (blacks out lungs)
  2. If sufficiently immobilized to prevent patient movement, a breathing technique may be used; slow, deep breathing with a minimum exposure time of 3-5 sec (4-5 desirable); give excellent results when a low MA is used. (using motion to blur out ribs, lungs, and adjacent structures to show the proximal humerus)
18
Q

What is being demonstrated (and on what surface) when performing a lateral humerus? (referring to the proximal end of the humerus)

A

Lesser tubercle on the medial surface.

19
Q

What must be on the finished radiograph of a humerus in order to be sure that all anatomy is present?

A

Structures of the shoulder joint to the complete elbow joint.

20
Q

When performing any bony extremity on an injured patient who may or may not be able to achieve the required positions, it is important to always get a minimum of 2 views that are –1– degrees different from one another.

A

90 degrees

21
Q

The correct centering for an upright abdomen exam is…

A

2 inches above umbilicus

22
Q

Name 3 reasons to perform a chest exam in the upright position.

A
  1. Diaphragm in its lowest position
  2. Prevent engorgement of pulmonary vessels
  3. You see the full/entire lung field
23
Q

Most bone work tends to be –1– scale and –2– contrast.

A
  1. short

2. high

24
Q

The largest carpal bone is the –1– which is located in the –2– row of carpal bones.

A
  1. Capitate, Os Magnum

2. Distal

25
What could be done to eliminate variations in density on the humerus radiograph if using conventional filming?
Use a filter
26
What is the structure that is located between the greater and lesser tubercles on the humeral head?
Bicipital groove
27
When is the transthoracic lateral exam utilized?
When the patient can't fully internally rotate their arm.
