A 23-year-old woman presents to your office complaining of a two day history of dysuria and urinary frequency. She may have had fever but denies any chills, rigors, back pain, nausea or vomiting. She has never had a urinary tract or vaginal infection previously, and is otherwise in excellent health. She takes no medications and is not allergic to any. Her physical exam including external genitalia and speculum examination is unremarkable.
