A patient is lying on his left lateral surface and the image receptor is placed along the anterior surface with the beam directed horizontally. What is the projection of the part?
 
 PA
  left lateral decubitus
  right lateral decubitus
  AP

Question 2

An exposure index reading that falls below the specified range indicates:
 
 will be optimal with post processing
  underexposure
  overexposure
  high SNR

Answer to Question 1

PA

Rationale: A patient lying on their left side with the IR along the anterior surface and a horizontal beam describes a left lateral decubitus position. Projection describes how the beam passes through the part. The projection will pass through the part PA.

Answer to Question 2

underexposure

Rationale: An exposure reading below the range of acceptable exposure range indicates that the image has been underexposed. Depending on how low the exposure is, it maybe noisy. Post processing will not be able to correct the image sufficiently.
