1. You are dispatched to a local college campus for a 21-year-old woman with abdominal pain. The dispatcher tells you that the patient has lower abdominal pain, fever, nausea, and vomiting. When you arrive on the campus, you are directed by campus police to the health center. There you find your patient lying supine on a bed. The patient tells you that she has had lower abdominal pain and a fever for the past 24 hours. She describes the pain as "achy" and says it gets worse with walking. She believes she has a "stomach virus" due to the fever and vomiting. Your partner obtains vital signs as you continue with your assessment. After finishing your SAMPLE history, you casually ask if she has had any other recent illnesses or if she has any other complaints. The patient says, "Well, since you mentioned it, I've been having some rather foul vaginal discharge lately. But I just thought it would go away." The patient denies pregnancy because she just finishe her menstrual period last week. What is the likely cause of this patient's condition, and how is it treated?
