Final answer:
1) private office
The nurse should opt for a private office to conduct the assessment with a client who has a history of sexual abuse, as it ensures privacy, security, and a comfortable environment to encourage open communication.
Step-by-step explanation:
Considering the client's history of sexual abuse in early adolescence, it is of utmost importance for the nurse to choose a setting for the assessment that provides a sense of security and privacy. The best option among those provided would be a private office. This setting ensures that the client feels safe to openly communicate without the fear of being overheard or disturbed, allowing for a more accurate assessment. This choice respects the client's traumatic history and supports the need for a secure environment that facilitates trust, comfort, and the delicate nature of revealing personal and potentially distressing information.
