RATIONALE: Confronting the client with the consequences of substance abuse helps to break through denial. Making threats (option 1) isn't an effective way to promote self-disclosure or establish a rapport with the client. Although the nurse should encourage the client to discuss feelings, the discussion should focus on how the client felt before, not during, an episode of substance abuse (option 3). Encouraging elaboration about his experience while getting high may reinforce the abusive behavior. The client undoubtedly is aware that drug use is illegal; a reminder to this effect (option 4) is unlikely to alter behavior.NURSING PROCESS STEP: ImplementationCLIENT NEEDS CATEGORY: Psychosocial integrityCLIENT NEEDS SUBCATEGORY: NoneCOGNITIVE LEVEL: Comprehension
