  2. Decrease MAS
  3. Decrease KVP
  4. Decrease MA only
Explanation
Answer: A - Increasing the MAS is the correct procedure for determining the change required when switching from a non-grid to a grid technique. Switching techniques requires an increase in mASs or kVp because the grid will absorb the primary radiation that would have otherwise reached film.
