Question 2  1 / 1 point Which of the following objects would be needed to perform a PA oblique projection of a finger? (1) 2-inch block (2) lead shield (3) 45-degree foam wedge   1 and 2   1 and 3    2 and 3   1, 2, & 3

 

Question 3  1 / 1 point For a PA oblique projection of the first digit (thumb) the hand is placed in the:   Supine    Prone   medial rotation position   lateral rotation position

 

Question 4  1 / 1 point For a PA projection of the hand, the central ray is directed to the:   Second MCP joint   Second PIP joint    Third MCP joint   Third PIP joint

 

Question 6  1 / 1 point Which of the following projections will demonstrate the radial head and neck free of superimposition?    AP Oblique with lateral rotation   AP Oblique with medial rotation   AP projection, partial flexion   AP projection, acute flexion

 

 

Question 8  1 / 1 point Which of the following projections clearly demonstrates the scaphoid?     PA in ulnar deviation/flexion   PA oblique in medial rotation   AP Oblique   Lateral

 

Question 9  1 / 1 point For the AP projection of the forearm, the hand is:    Supinated   Pronated   Placed in a lateral position   Placed in a 45 degree oblique

 

Question 10  1 / 1 point For the AP projection of the elbow, the humeral epicondyles are:   Perpendicular to the IR    Parallel to the IR   Superimposed over each other   Not demonstrated

 

Question 11  1 / 1 point Which positioning characteristic best indicates that the humerus is properly positioned for the AP projection of the humerus?   The hand is pronated.   There is uniform contact with the IR for the entire posterior surface of the humerus.    The plane of the humeral epicondyles is parallel with the IR   The plane of the humeral epicondyles is perpendicular with the IR

 

Question 13  1 / 1 point How many degrees should the elbow be angled for an AP oblique projection in lateral rotation?   25 degrees   30    45   60

 

Question 14  1 / 1 point If a patient is unable to extend the forearm for an AP projection of the elbow, how many projections are necessary to avoid distortion of the joint?    2   3   4   5

 

Question 15  1 / 1 point Rotating the arm medially for a lateral projection of the humerus will place the epicondyles:   At a 30 degree angle with the IR   At a 45 degree angle with the IR   Parallel with the IR    Perpendicular to the IR

 

Question 16  1 / 1 point Which fat pad lies parallel with the anterior aspect of the proximal radius?   Anterior    Supinator   Transverse   Posterior

 

Question 18  1 / 1 point The central-ray angulation for both of the axiolateral projections (Coyle method) of the elbow is:   30 degrees   35 degrees   40 degrees    45 degrees

 

Question 19  1 / 1 point Which description best explains how radial crossover occurs when the forearm is demonstrated?    During the AP projection the hand is pronated.   During the AP projection, the hand is supinated.   During the lateral projection, the arm is fully extended with the hand flexed.   During the lateral projection, the radial and ulnar styloid processes are superimposed with each other.
