How should the technique be adjusted from the routine for an AP abdomen projection (lateral decubitus position) in a patient with ascites or a bowel obstruction?
1. Increase the mAs 30 to 50.
2. Decrease the mAs 30 to 50.
3. Increase the kVp 5 to 8.
4. Decrease the kVp 5 to 8.

b. 1 and 4 only
c. 2 and 3 only
