Review Question - QID 214314

A 25-year-old woman presents to the emergency department with complaints of abdominal pain. She reports abdominal pain that initially began around her belly button 1 day prior. The pain progressively worsened to 8/10 and is now concentrated across the lower abdomen. It is described as intermittent and sharp. She denies any fever, chills, diaphoresis, trauma, or lightheadedness but endorses urinary urgency over the past 2 days. Past medical and family histories are unremarkable. The patient drinks socially and denies any drug use. She is sexually active with her boyfriend and uses an etonogestrel/ethinyl estradiol vaginal ring as contraception. Her last menstrual period was 5 weeks ago, but she reports some spotting that began yesterday. Her temperature is 98.1°F (36.7°C), blood pressure is 146/75 mmHg, pulse is 98/min, and respirations are 13/min. A physical examination is significant for tenderness at the lower abdomen with moderate guarding. Laboratory workup is largely unremarkable. In addition to symptomatic management, what is the best next step in this patient?
