RATIONALE: Because the client with anorexia nervosa may discard food or induce vomiting in the bathroom, the nurse should provide one-on-one supervision during meals and for 1 hour afterward. Option 2 wouldn't be therapeutic because other clients may urge the client to eat and give attention for not eating. Option 3 would reinforce control issues, which are central to this client's underlying psychological problem. Instead of giving the client unlimited time to eat, as in option 4, the nurse should set limits and let the client know what is expected.NURSING PROCESS STEP: ImplementationCLIENT NEEDS CATEGORY: Psychosocial integrityCLIENT NEEDS SUBCATEGORY: NoneCOGNITIVE LEVEL: Knowledge
