Final answer:
Appropriate interventions for a client with bulimia nervosa include identifying trigger foods and limiting meal times to about 30 minutes to prevent excessive focus on eating, rather than including liquid supplements or weighing the client at bedtime.
Step-by-step explanation:
When updating the plan of care for a client with bulimia nervosa, a nurse should include interventions that directly address the client's eating disorder behaviors and contribute to recovery. It is not appropriate to include a liquid supplement with meals for a client who is above their ideal body weight as they may not need additional nutrition to gain weight. Instead, one appropriate intervention would be to identify the client's trigger foods. This involves helping the client to recognize specific foods that may prompt binge eating episodes and understanding their associated thoughts and behaviors. Weighing the client should be done consistently in the morning after voiding and before eating or drinking to avoid any fluctuations due to meals and fluid intake, rather than at bedtime. Limiting meal times to approximately 30 minutes helps to prevent excessive focus on food, rather than allowing extensive periods for eating.
