The PMHNP is evaluating a new 17-year-old client with a history of delinquent behavior, including a recent arrest for vandalism. The nurse practitioner suspects conduct disorder based on the client's history and current presentation. According to Erikson, such behavior is a result of the failure to resolve which psychosocial developmental stage?

Choice A reason: Industry vs. inferiority occurs in school-aged children and relates to competence; failure here may affect self-esteem but not typically adolescent delinquency. Choice B reason: Intimacy vs. isolation occurs in young adulthood and is concerned with forming intimate relationships, not adolescent behavior. Choice C reason: Identity vs. Role Confusion occurs during adolescence. Failure to establish a coherent sense of self may manifest as conduct problems, delinquent behavior, and role confusion, consistent with this client. Choice D reason: Initiative vs. Guilt occurs in early childhood and relates to asserting power and independence; it is not the stage directly tied to adolescent conduct disorder.
