Review Question - QID 210844

A 26-year-old African American woman presents to the clinic with burning upon urination. The patient describes increased frequency, urgency, and a painful sensation at the urethra when urinating for the past 3 days. She also reports increased vaginal discharge and abnormal odor during the same time. The patient denies fever, flank pain, or hematuria (though the patient does report a dark brown color of the urine). Her past medical history is significant for Crohn disease which is controlled with sulfasalazine. Her temperature is 98.6°F (37°C), blood pressure is 118/71 mmHg, pulse is 78/min, respirations are 13/min, and oxygen saturation is 98% on room air. What is the definitive treatment for the described condition?
