Which of the following describes the best method of R/L marker placement on the PA chest?
The Right or Left marker should be placed low on the image receptor.
Any of these marking locations is sufficient.
The Right or Left marker should be placed directly beside the rib cage.
The Right or Left marker should be placed above the shoulder.
The Right or Left marker should be placed above the shoulder.
Rationale: The best placement of the Right or Left marker on the PA chest would be above the shoulders.

Placing the marker beside the patient could result in obscuring the lateral lung.
