Limit time allotted for meals. 2. Identify maladaptive eating behaviors. 3. Discuss feelings associated with eating behaviors. 4. Focus on regaining control

C. This is correct. The best for scheduling group therapy immediately after meals is to address the emotional issues related to eating behavior, as it enables the nurse to observe clients following meals.

Limiting time allotted for meals minimizes clients' attention on food and eating
