 75 kVp at 400 mAs, and 1 second
  75 kVp, 100 mA, and 3 seconds
  75 kVp, 200 mA, and 4 seconds
  75 kVp at 200 mAs and 1 second

Question 2

Which projection of the foot will demonstrate the metatarsals superimposed?
 
 mediolateral
  AP
  PA oblique
  AP oblique

[samiel-sayed]

Answer to Question 1

75 kVp, 100 mA, and 3 seconds

Rationale: Breathing technique requires that the mA and time be set independently. For a breathing technique to be effective, a time of 3-4 seconds must be established. The lower mA station applied with the time will help reduce the patient dose.

Answer to Question 2

mediolateral

Rationale: The mediolateral will superimpose the metatarsals if properly positioned. The foot should be dorsiflexed and arranged so the plantar surface of the foot is perpendicular to the image receptor.
