Answer 1

a. Remote

Question 2

Referring to previous question, what should be done with this arm when performing the transthoracic lateral humerus.

Answer 2

c. Elevate it above the head

Question 3

When performing the AP position/projection of the humerus, the –1– is being demonstrated at the proximal end of the humerus.

Answer 3

c. Greater tubercle on lateral surface

Question 4

When positioning a lateral humerus, the CR should be directed to the –1–.

Answer 4

c. Humeral shaft

Question 5

When the humerus is in flexion, the –1– process is in the –2– fossa.

Answer 5

c. 1 Coronoid 2 Coronoid

Question 6

The –1– of the humerus hinges with the radial head.

Answer 6

d. Capitulum

Question 7

The humeral head articulates with the –1– of the –2– to form the shoulder joint.

Answer 7

d. 1 Glenoid fossa 2 Scapula

Question 8

If the patient can’t adequately drop the affected shoulder/humerus down when performing the transthoracic lateral, the CR may be angled –1– degrees –2– in order to separate the shoulders from one another.

Answer 8

c. 1 10-15 2 Cephalic

Question 9

When performing the routine humerus positions, the respirations should be –1–.

Answer 9

c. Suspended

Question 10

Explain why the upright humerus may be the method of choice for this exam .

Answer 10

It is less painful for the patient.

Question 11

What is the method name for the transthoracic lateral humerus.

Answer 11

Lawerence Method

Question 12

When would you perform the x-table lateral for the distal humerus?

Answer 12

When you can’t fully internally rotate the humerus.

Question 13

In the AP position/projection of the humerus, a line drawn through the epicondyles should be –1– to the IR if the patient was properly positioned.

Answer 13

Parallel

Question 14

The IR/ cassette should be placed –1– inches –2– the affected shoulder when performing the transthoracic lateral.

Answer 14

1. 1 1/2 inches

2. above

Question 15

If performing the recumbent lateral humerus , what surface of the hand is placed against or alongside the patient?

Answer 15

Posterior

Question 16

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

Answer 16

Supination

Question 17

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

Answer 17

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)

Question 18

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

Answer 18

Lesser tubercle on the medial surface.

Question 19

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

Answer 19

Structures of the shoulder joint to the complete elbow joint.

Question 20

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.

Answer 20

90 degrees

Question 21

The correct centering for an upright abdomen exam is…

Answer 21

2 inches above umbilicus

Question 22

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

Answer 22

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

Question 23

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

Answer 23

1. short

2. high

Question 24

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

Answer 24

1. Capitate, Os Magnum

2. Distal

Question 25

What could be done to eliminate variations in density on the humerus radiograph if using conventional filming?

Answer 25

Use a filter

Question 26

What is the structure that is located between the greater and lesser tubercles on the humeral head?

Answer 26

Bicipital groove

Question 27

When is the transthoracic lateral exam utilized?

Answer 27

When the patient can’t fully internally rotate their arm.
