Hematemesis describes vomiting blood. Which option is correct?

• A. Emesis
• B. Hematochezia
• C. Hematemesis
• D. GI cocktail

Answer: (C)

The main term tested is the specific name for a symptom: vomiting blood. Vomiting blood is described as hematemesis, which directly identifies the act of vomiting blood and points to an upper GI source. Emesis is the general term for vomiting itself, not specifically blood. Hematochezia refers to blood in the stool, typically seen as red or maroon stools, indicating a lower GI bleed (or a very brisk upper GI bleed in rare cases). A GI cocktail is simply a mixture of medications used for symptom relief in some GI complaints, not a term for a symptom. So the best match for the described scenario is hematemesis, since it names the exact symptom of vomiting blood and signals a possible upper GI source that needs prompt evaluation.
