Lateral Sternum
PA Oblique Ribs
AP Oblique Ribs
What is the recommended SID for the RAO sternum position?
40 inches
44 inches

A patient has an injury to their left anterior upper ribs. Which would best demonstrate that area?
PA and RAO
AP and LAO
AP and RPO
PA and LPO
Which of the following is the correct breathing instruction for AP Oblique Upper Ribs?
Full inspiration
Full expiration
No breathing instructions required
Shallow breathing
Which of the following positions will best demonstrate the axillary portion of the left ribs?
LAO
RPO
LPO
PA
Which of the following would be incorrect when obtaining a lateral sternum x-ray.
Have the patient suspend deep inspiration
Rotate the shoulders back and have the patient lock hands behind back
Have the patient take slow, shallow breaths
Adjust the patient in a true lateral position
Which would best demonstrate an injury to the left posterior lower ribs?
AP and RAO
PA and LPO
AP and LPO
PA and RPO
On an RAO sternum image the receptor exposure was optimal, but lung markings obscured the anatomy of interest. The following exposure factors were used: 1s, 35 mA, 75 kVp. How could the breathing technique be improved?
Increase the time, decrease the mA.
Decrease the kVp, increase the mA
Increase the kVp, decrease the time.
Do not alter the technique, this is a positioning error.
A radiograph of an RAO sternum reveals that it is free of superimposition with the spine. What must be done to eliminate this problem?
No change necessary.
Increase rotation.
Decrease rotation.
Perform an LPO instead.
A lateral sternum image shows that the ribs are superimposed over the anatomy of interest. How can this be corrected?
Ensure the patient is in a true lateral position.
Angle the CR 10 degrees caudad.
Increase the kVp.
Increase the SID.
Which two projections must be taken for an injury to the left posterior lower ribs?
AP and LPO
AP and RAO
PA and LPO
PA and RAO
A PA image of the SC joints demonstrates that the left SC joint is farther from the sternum than the right. What specific positioning error is present?
slight right rotation
tilt of the upper thorax
slight left rotation
excessive angulation of the CR
An image of an LAO projection of the ribs demonstrates the right axillary ribs are foreshortened and the left are elongated. Which of the following is the most likely reason?
CR angulation was incorrect
the technologist should have performed a PA projection not an RAO
an RAO was performed rather than the LAO
the patient requires more rotation to the left
