A nurse is planning care for an adolescent who is withdrawn and avoids social group activities. Which of the following interventions should the nurse plan to include?

A. Encouraging the adolescent to spend more time alone may reinforce their withdrawal and does not promote social interaction or engagement. B. Assigning the adolescent as a leader may increase anxiety and exacerbate their withdrawal rather than encourage socialization. C. One-on-one counseling can provide a safe space for the adolescent to express feelings and explore the reasons for their withdrawal, which is a supportive and therapeutic intervention. D. Focusing solely on academic achievements may lead to further isolation and does not address the need for social skills development and peer interaction.
