Final answer:
The nurse's opportunity when taking a sexual history from an adolescent is to provide anticipatory guidance related to sexual health, address STI prevention, and maintain a balance between patient privacy and health needs.
Step-by-step explanation:
When the nurse takes a sexual history from an adolescent, it presents an opportunity to provide anticipatory guidance related to sexual health. This guidance includes discussing safe sex practices, the importance of consent, and how to prevent sexually transmitted infections (STIs).
The nurse must balance the need for confidentiality with the adolescent's health needs. Parents' desires to know about their child's health must be considered against the adolescent's rights to privacy. Contacting sexual partners can be essential for treating and preventing the spread of STIs, but it must be handled with sensitivity to respect patient confidentiality.
