Answer to Question 1

using a higher ratio grid

Rationale: Higher ratio grids are more efficient at absorbing scatter. Grid ratios can be 5:1 . 6:1, 8:1, 10:1, 12:1, or 16:1.

Answer to Question 2

C1-C2

Rationale: C1 and 2 will not be visible on the AP axial c-spine due to the mandible and base of the skull. The AP axial will demonstrate the vertebral bodies of C3-7.
