Which condition is suggested by vomiting blood, coffee-ground emesis, bloody stool, dark tarry stool, severe back or flank pain, and a pulsating abdominal mass?

• A. Respiratory condition
• B. GI Disorders
• C. Neurologic disorder
• D. Cardiovascular disease

Answer: (B)

Vomiting blood, coffee-ground emesis, bloody stool, and dark tarry stool are classic signs of bleeding somewhere in the gastrointestinal tract. The blood’s appearance changes depending on how long it has been in the GI system: fresh blood from an upper GI source can cause vomiting of bright red blood, blood that has had time to interact with stomach acid becomes coffee-ground emesis, and digested blood moving through the intestines turns stool dark and tarry (melena). When these signs appear together, they point to a GI source of bleeding and a GI-based emergency.

The severe back or flank pain and a pulsating abdominal mass raise important red flags for other serious conditions (such as a vascular issue like an abdominal aortic aneurysm), but the primary clues here—the bleeding manifestations—are most directly categorized under GI disorders. Respiratory or neurologic conditions wouldn’t typically present with this pattern of GI bleeding, and while cardiovascular emergencies can accompany GI bleeding, the main clinical theme suggested by the symptoms is GI tract pathology.
