Question 2

Which of the following would be the most effective means to reduce dose to the patient?
 
 reduce or eliminate the need for repeat projections
  use the protective barrier whenever possible
  use AEC
  use a higher mA and less time

[Sophiapenny]

Answer to Question 1

high contrast

Rationale: High scale or short contrast is a scale of contrast with greater differences between the shades, making the contrast scale more black and white.

Answer to Question 2

reduce or eliminate the need for repeat projections

Rationale: The best means to reduce exposure would be to reduce the number of repeat radiographs on a patient. In addition, good communication and technical considerations such as technique paired with image receptors.
