What advice should you give Zahra? Check all that apply.

Isaac should be evaluated and cleared by a doctor before they have further sexual contact, and Zahra should get tested because she may have been exposed to an STI. STIs can spread through oral sex, so using a condom can reduce the risk. Not having had intercourse does not rule out exposure, and some STIs cause no symptoms, so choices C and E are not good advice.
