Which positioning maneuver should be applied to the lateral lumbar spine to promote opening of the intervertebral disk spaces?
 
 provide support under the patient's knees
  have patient fully extend legs
  provide a wedge of support under the waist
  have the patient pull knees all the way towards the chest

Question 2

Selection of an anatomical part on the control panel which then registers the preprogrammed exposure factors defines which system:
 
 CR
  anatomic programmed radiography
  DR
  automatic exposure control

Answer to Question 1

provide a wedge of support under the waist

Rationale: In order to image the intervertebral disk spaces open, the lumbar spine must be positioned parallel to the image receptor to allow the divergent beam to pass through the disk spaces.

Answer to Question 2

anatomic programmed radiography

Rationale: APR systems are programmed to have exposure factors configured for the anatomic parts and the specific projection selected.
