A nurse is talking with a 13-year-old female client who is having her annual health-screening visit. Which of the following comments by the client should concern the nurse?

A. "My parents treat me like a baby sometimes." This statement reflects a common adolescent feeling of striving for independence and experiencing frustration when treated as a child. It is a normal part of adolescent development and not a cause for immediate concern. B. "There's a pimple on my face, and I worry that everyone will notice it." Concern about appearance is typical for adolescents due to the increased focus on body image and peer perception. This statement is a normal expression of adolescent self-consciousness. C. ``I start taking ibuprofen a few days before my period starts." Using ibuprofen preemptively for menstrual cramps is a reasonable self-care practice for adolescents experiencing menstrual discomfort. This statement does not indicate any immediate health concern. D. "None of the kids at my school like me, and I don't like them either." This statement indicates social isolation and potential issues with peer relationships, which can be a red flag for emotional distress or depression. It may suggest that the adolescent is experiencing significant difficulties in their social life that could lead to more serious mental health concerns.
