Which anatomy will indicate rotation on a lateral skull?
 
 greater wings of the sphenoid
  auricles
  c-spine
  superior orbital margins

Question 2

Which factor should be considered when trying to reduce the possibility of patient motion?
 
 decrease SID
  decrease mAs
  decrease time
  decrease kVp

Answer to Question 1

greater wings of the sphenoid

Rationale: Rotation is evidenced on a radiograph when the anatomy is shifted anterior to posterior to one another. The mandibular rami or greater wings of the sphenoid will indicate rotation.

Answer to Question 2

decrease time

Rationale: A reduction in time should be applied in instances where patient motion is of concern. If a faster time is needed to avoid motion, mA may be increased accordingly.
