Which scenario indicates starting PEP?

Explanation:
Post-exposure prophylaxis (PEP) is started after a potential exposure to HIV to reduce the chance of infection by stopping the virus early. A broken condom during sex creates a real exposure risk because HIV can be transmitted through sexual fluids, and starting PEP promptly—ideally within hours and no later than about 72 hours after exposure—significantly lowers the likelihood of acquiring HIV. The usual course is a 28-day regimen of antiretroviral medications begun under medical supervision, with HIV testing and follow-up. The other scenarios don’t reflect a post-exposure situation: regular condom use reduces risk and doesn’t indicate exposure needing PEP; vaccination isn’t a treatment for HIV; a routine checkup is unrelated to a potential exposure event.
