The correct answer is option 4. Attempting to establish a trusting relationship with the adolescent
Step-by-step explanation:
The most important initial nursing intervention for an adolescent with anorexia nervosa is attempting to establish a trusting relationship with the adolescent.
This is crucial because individuals with anorexia nervosa often have a distorted body image and are excessively concerned about their weight.
By establishing trust, the nurse can create a supportive environment where the adolescent feels comfortable discussing their concerns and challenges related to eating.
Through a trusting relationship, the nurse can then address the underlying issues and work towards a comprehensive treatment plan.
