AP shoulder and recumbent AP scapular Y projection

21

part 7 refers to (picture)

22

a rodiograph of a transthoracic lateral projection reveals that it is difficult to visualize the proximal humerus due to ribs and lung markings. the following exposure factors were used: 75 kv, 30 mAs,40-inch sid,grid,suspended respiration. which of the following changes will improve the quality of the image?

use a breathing technique

23

shoulder radiography produces significant dose to the breast and thyroid gland.

24

which term describes the medial end of the clavicle?

25

situation: a patient comes to the ED with a possible right AC joint separation. right clavicle and AC joint exams are ordered. the clavicle is taken first, a small linear fracture of the midshaft of the clavicle is discovered. what should the technologist do?

consult with the ED physician before continuing with the AC joint study

26

situation: a patient enters the ED with a possible AC joint separation. the patient is paraplegic, therefore the study cant be done erect. which of the following routines would be performed to diagnose this condition?

non-weight nearing and weight-bearing type projections performed with the patient recumbent by pulling down on the shoulders

27

a radiograph of an AP clavicle reveals that the sternal extremity is partially collimated off. what should the technologist do?

repeat the AP projection and correct collimation

28

which rotation of the humerus will result in a lateral position of the proximal humerus?

internal rotation(epicondyles perpendicular to the image receptor)

29

a radiograph for an AP projection with external rotation of the proximal humerus reveals that the greater tubercle is profiled laterally. What should be changed to improve this image for a repeat exposure?

positioning is acceptable; dont repeat it.
