Q. A 24-year-old female presents to the clinic with a 4-day history of painful urination, increased frequency of urination, and a constant urge to void. She also reports waking up multiple times at night to urinate. The patient complains of mild discomfort in the lower abdominal region but denies any fever, chills, flank pain, or vaginal discharge. She admits to being sexually active with one partner and sometimes forgoes using barrier protection. On examination, her vitals are stable, and the suprapubic region is tender to palpation. No costovertebral angle tenderness is noted. A urine dipstick test reveals moderate leukocytes, positive nitrites, and a few red blood cells, and is negative for ketones and protein. What is the most appropriate next step of management for this patient?
