They'd prob. give you Ciprofloxacin or Levofloxacin IF it's a UTI. For an STD, it's different. I am not sure why she treated you for Gonorrhea if you've not been diagnosed with it yet. I assume she injected you with Ceftriaxone. Doxycycline is for Chlamydia, but can also be used for Gonorrhea; just it's not a shot. There is no cure for HSV or HPV as they are viruses.
If she's a registered nurse, then I am sure her intentions were good. However, how does she treat a patient without results? They didn't test there with the urine? A rapid result is within 20 minutes. Wonder if you saw a nursing student, not actual nurse. That means she's under the guidance of registered nurse, PA or doctor.
Follow the nurses directions, as she's the one who treated you. However, I'd call in the morning to see if they have the results and then question them if they do not have the results, why were you given antibiotics? In the end, you will be fine, but the practice of giving antibiotics prior to results is why we have antibiotic resistance to many common infections and bacteria.
