Final answer:
Having multiple sexual partners, engaging in unprotected sex, having a history of STIs, using intravenous drugs, and being sexually active at a young age are all risk factors that may indicate the need for sexually transmitted infection (STI) screening.
Step-by-step explanation:
If a person has a personal health history that indicates risk factors for sexually transmitted infections (STIs), it may be necessary for them to undergo STI screening. Risk factors that may indicate the need for screening include:
- Having multiple sexual partners
- Engaging in unprotected sex
- Having a history of STIs
- Using intravenous drugs
- Being sexually active at a young age
If Nadia has engaged in any of these risky behaviors or if her doctor suspects that she may have been exposed to an STI based on her symptoms, then STI screening would be appropriate.
