Radiography units with APR, when activated, will do all of the following except:
 
 determine AEC detector(s)
  determine kVp
  determine mAs
  set the necessary tube SID

Question 2

Which criteria justifies that MML was aligned perpendicular to the image receptor for the Water's method?
 
 the petrous pyramids fill the lower one third of the maxillary sinuses
  the petrous pyramids fall below the maxillary sinuses
  the petrous pyramids fill the lower one third of the orbits
  the petrous pyramids fill the orbits

Answer to Question 1

set the necessary tube SID

Rationale: A radiographic system with APR displays preconfigured exposure factors when the technologist selects an anatomic area. Factors such as kVp and mAs for the particular area are automatically displayed. AEC cells may also be predetermined by the APR.

Answer to Question 2

the petrous pyramids fall below the maxillary sinuses

Rationale: A properly positioned Water's method raises the chin until the MML is perpendicular to the IR. If the MML is truly perpendicular, the petrous pyramids will drop below the level of maxillary sinuses.
