not sure, but I think maybe 1. 2 is bad because it's internet, and the professional will more likely to give the best advice. 3 maybe, but the problem is asking that she is not sure about the treatment, and needs to understand clearly instead of letting someone decide. 4 why would someone discuss it after the appointment, and why would the nurse discuss it. 1 is hella sketchy but I think it's the best out all of them, if not it's probably 3. Hope that helps!
