Final answer:
The most appropriate nursing diagnosis for the student is Risk for Complicated Grieving due to the loss of both parents in a car accident after relocating to a new city.
Step-by-step explanation:
The most appropriate nursing diagnosis for a 19-year-old only child who just lost both parents in a car accident after relocating to a new city is Risk for Complicated Grieving.
Grief is a natural response to loss, and in this case, the student is experiencing the loss of both parents, which puts them at risk for complications in their grieving process. The suddenness of the accident, combined with the recent relocation, can compound the emotional distress they are feeling.
Some potential manifestations of complicated grieving may include difficulty sleeping, intense feelings of sadness, changes in appetite, difficulty concentrating, and social withdrawal. It is important for the nursing team to provide support and monitor the student's emotional and mental well-being as they navigate this difficult time.
