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.

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
