A nurse is caring for an adolescent who states, "I joined the track and field team, so I won't argue with my brothers anymore." The nurse should identify that the client is using which of the following defense mechanisms?

A. Denial is incorrect. Denial involves refusing to acknowledge reality or a distressing situation, which is not evident in this scenario. The adolescent is aware of the conflict and has chosen a constructive way to address it. B. Sublimation is correct. Sublimation is the process of channeling unacceptable impulses (such as frustration or aggression) into socially acceptable activities (such as sports or creative pursuits). By joining the track and field team instead of arguing with his brothers, the adolescent is redirecting energy into a positive outlet. C. Regression is incorrect. Regression occurs when an individual reverts to an earlier stage of development in response to stress. Examples include an older child suddenly sucking their thumb or having temper tantrums. The adolescent in this scenario is demonstrating maturity, not regression. D. Repression is incorrect. Repression involves unconsciously blocking distressing thoughts or emotions from awareness. The adolescent is not avoiding or forgetting about the conflict but is instead managing it through physical activity.
