A sign of an internal abdominal injury is?

A swollen or rigid abdomen is a key sign of an internal abdominal injury because it indicates that there may be bleeding or fluid accumulation within the abdominal cavity. When injuries occur, such as a rupture of organs, the body often responds by tightening the abdominal muscles in an attempt to protect the affected area. This rigidity can be felt during a physical examination.

Furthermore, a swollen abdomen may suggest the presence of internal bleeding, which is a critical situation requiring immediate medical attention. The body’s inflammatory response to injury can also lead to swelling, causing the abdomen to appear distended. Recognizing this symptom is crucial for effective assessment and intervention in emergency situations.

While sweating and seizures might be symptoms present in various medical emergencies, they are not as directly indicative of internal abdominal injuries as rigidity and swelling of the abdomen.
