Answer to Question 1

increased dose

Rationale: Increased collimation refers to increasing the collimation to reduce the field size of exposure on the patient. This will result in a decreased dose to the patient and potential higher contrast.

Answer to Question 2

base of the 5th metatarsal

Rationale: The base of the 5th metatarsal is important to include on all ankle projections as the base of the 5th metatarsal is a common fracture location. Evaluating for secondary injury is critical.
