Open wounds or sores within the digestive tract, usually in the stomach or the beginning of the small intestine?

• A. Hernia
• B. Ulcers
• C. Gastroenteritis
• D. Peritonitis

Answer: (B)

Ulcers are breaks or erosions in the mucosal lining of the digestive tract, most commonly in the stomach or the first part of the small intestine (the duodenum). This description fits because an ulcer is an open sore where tissue has been worn away by acid and digestive enzymes, sometimes due to infection with Helicobacter pylori or NSAID use. The erosion can bleed and, if severe, may perforate the wall, causing internal bleeding or an acute abdomen. This is why ulcers are the best match for “open wounds or sores within the digestive tract, usually in the stomach or the beginning of the small intestine.”

A hernia is tissue protruding through an opening, not an ulcer. Gastroenteritis is inflammation of the GI tract causing vomiting and diarrhea, not a localized mucosal sore. Peritonitis is inflammation of the peritoneum, usually from infection or organ rupture, not a superficial mucosal ulcer. In EMS, look for signs of GI bleeding such as vomiting blood or black stools, monitor vitals, and prepare for transport with IV access and pain management as needed.
