Answer to Question 2

Rationale:
1. The adolescent probably will want friends present at times, instead of a parent at all times.
2. Concern with body image and development of independence are both significant concerns in the adolescent age group.
3. The 14-year-old typically will not want a parent or nurse to do all the care for her. She is interested in her body, and wants to start caring for herself.
4. Missing school is not a positive aspect for this age, as frequent contact with peer groups is so important.
