Final answer:
Option A), B) and C). In the plan of care for a client with anorexia nervosa, the nurse should include interventions such as weighing the client weekly, staying with the client after meals, and allowing the client to schedule mealtimes.
Step-by-step explanation:
The nurse should include the following interventions in the plan of care for a client with anorexia nervosa:
- Weigh the client once weekly at the same time of the day: Regular weighing helps monitor the client's progress and ensures they are gaining weight appropriately.
- Stay with the client for 30 minutes after meals: This helps prevent purging behaviors and provides support during the post-meal period.
- Allow the client to schedule mealtimes: This empowers the client to have control over their eating, which can improve compliance with the plan of care.
