ARRT extremities practice questions
WITH Correct Answers 100% Pass
When performing the lateral humerus with the mediolateral projection,
which of the following does not apply?
1. position patient with back toward IR
2. oblique the patient 20 to 30 degree, to bring the humerus in contact
with IR
3. center the CR midpoint of humerus
4. flex elbow to position epicondyles perpendicular to IR. -
[ANSWER]: position the patient with back toward the IR.
(they will be facing the IR and obliqued 20 to 30 degrees from PA)
QUESTION: Proper positioning for the lateral calcaneus will result in:
1) Open joint space between calcaneus and cuboid
,2) Superimposed talar domes
3) Lateral malleolus free of superimposition -
[ANSWER]: 1 and 2 only
(it will result in open joint spaces between the calcaneus and cuboid, the
talus and calcaneus, and the talus and the navicular. the lateral malleolus
will partially superimpose the distal tibia and talus.)
QUESTION: The greater tubercle should be visualized in profile in
which of the following?
1. AP shoulder, external rotation
2. AP shoulder, internal rotation
3. AP elbow
4. lateral elbow -
[ANSWER]: AP shoulder, external rotation
,QUESTION: The lesser tubercle should be visualized with what
projection of the shoulder? -
[ANSWER]: AP shoulder, internal view (this places the humerus in a
true lateral position.)
QUESTION: How can OID be reduced for a PA projection of the
wrist? -
[ANSWER]: flex the metacarpophalangeal joints
QUESTION: How is a hand positioned for a PA projection of the
wrist? -
[ANSWER]: hand is pronated and the fingers extended, but you need to
reduce the OID by flexing the MCP joints
QUESTION: What is radial deviation? -
[ANSWER]: it is flexing the that brings the thumb closer to the radial
bone of the forearm
, QUESTION: What is ulnar deviation? -
[ANSWER]: it is flexing the pinky finger closer to the ulnar bone or
outside of the forearm.
QUESTION: Why would you not use the radial deviation position for
looking at the scaphoid? -
[ANSWER]: it foreshortens it
radial deviation is better for medial carpals
QUESTION: Which of the following articulate(s) with the bases of the
metatarsals?
1. The heads of the first row of phalanges
2. The cuboid
3. The cuneiforms -
