Answer to Question 1

cross-table lateral ankle

Rationale: Use of a horizontal beam will demonstrate air-fluid level when a patient's condition prevents upright positioning.

Answer to Question 2

speed is increased as phosphor size increases

Rationale: Phosphor size and speed are directly related. As the phosphor size increases so does the screen speed.
