A patient presents with abdominal pain, fever, dysuria, and pain while walking; nonemergency transport is recommended. Which condition best fits this presentation?

• A. Urinary tract infection
• B. Kidney stones
• C. Pelvic inflammatory disease
• D. Gastroenteritis

Answer: (C)

Pelvic inflammatory disease fits this presentation because an ascending infection of the upper female reproductive tract causes pelvic or lower abdominal pain with fever, and may be accompanied by urinary symptoms like dysuria. The pain that worsens with movement or walking reflects tenderness from inflamed pelvic structures, which is a hallmark of PID. When a patient is stable enough for nonemergency transport, outpatient management with antibiotics targeting the common sexually transmitted pathogens (such as gonorrhea and chlamydia) is appropriate, along with STI testing and partner notification.

In contrast, a urinary tract infection can cause dysuria and sometimes fever, but it usually lacks the characteristic pelvic pain that worsens with movement. Kidney stones produce severe, sharp flank or groin pain that is often colicky and tends not to present with dysuria and mild fever in the same pattern. Gastroenteritis presents with abdominal pain plus prominent GI symptoms like vomiting or diarrhea and does not typically feature dysuria or pelvic tenderness.
