RTBC EXAMS 2 ALL ANSWERS AND QUESTIONS SET
A+
✔✔Identify the structure that is represented by the letter (D) in the following image: -
✔✔Coracoid process
✔✔1. Where should the central ray be directed for an anteroposterior (AP) projection of
the scapula? - ✔✔2 inches (5 cm) inferior to the coracoid
✔✔Which of the following represents the correct breathing instructions for an
anteroposterior (AP) scapula projection? - ✔✔Slow respiration
✔✔Which two of the following are appropriate evaluation criteria for a lateral projection
of the scapula? (Select two) - ✔✔- Scapular body free of rib superimposition
- Humerus does not superimpose area of interest
✔✔How should the patient's affected arm be positioned when performing an
anteroposterior (AP) projection of the scapula? - ✔✔Abducted 90 degrees with the
elbow flexed and the hand supinated
✔✔Why must a patient's arm be abducted 90 degrees for a routine anteroposterior (AP)
projection of the scapula? - ✔✔Abducting the arm moves the scapula laterally for
minimal superimposition by the ribs
✔✔Mr. Garcia is a 40-year-old patient with an order for a routine scapula series due to
pain in the area for the past two weeks. He has had no prior injury and is able to move
and cooperate for the radiographic examination. How could the positioning error
demonstrated in the anteroposterior (AP) projection from the scapula series in the
following image be corrected? - ✔✔Abduct the patient's arm 90 degrees from the body
so the scapula is less
superimposed by the thoracic structures
, ✔✔Which of the following best identifies the projection demonstrated in the following
radiograph? - ✔✔Lateral scapula
✔✔Which two of the following are acceptable patient positions when performing an
anteroposterior (AP) scapula radiograph?
(Select two) - ✔✔- Standing at the upright bucky
- Lying supine on the radiographic table
✔✔For a lateral scapula radiograph, what is the correct patient position and source-to-
image distance (SID)? - ✔✔Patient standing at the upright bucky or lying prone, 40-inch
(102 cm) SID
✔✔What is the recommended central ray entrance point for a lateral scapula
radiograph? - ✔✔At the medial aspect of the scapula
✔✔Which of the following is the correct central ray entrance point for an anteroposterior
(AP) projection of the clavicle? - ✔✔At the mid-clavicle
✔✔A hypersthenic patient is scheduled to have routine clavicle images. The images are
obtained with the patient in the supine position. Which of the following demonstrates the
appropriate amount of tube angulation to obtain the images? - ✔✔15-degree cephalic
✔✔Which of the following are the correct breathing instructions for an anteroposterior
(AP) axial projection of the clavicle? - ✔✔Suspended inspiration
✔✔Which of the following represents a correct evaluation criterion for an
anteroposterior
(AP) axial projection of the clavicle? - ✔✔Acromioclavicular (AC) joint and
sternoclavicular (SC) joint are included on the image
✔✔Identify the structure that is represented by the letter (A) in the following image: -
✔✔Sternoclavicular (SC) joint
✔✔The image demonstrated is best described as an anteroposterior (AP) projection of
the: - ✔✔Left clavicle
✔✔Identify the structure that is represented by the letter (C) in the following image: -
✔✔Acromioclavicular (AC) joint
✔✔Which of the following describes the appropriate central ray angle for an
anteroposterior (AP) axial projection of the clavicle? - ✔✔Angled 15 - 30 degrees
cephalad
