Which findings in a trauma patient suggest ongoing intra-abdominal bleeding?

• A. Tachycardia with hypotension unresponsive to fluids, abdominal distension, decreasing hematocrit, rising lactate, and positive FAST
• B. Normal vitals and stable hematocrit
• C. Hyperkalemia and widened pulse pressure
• D. Low lactate and normal hematocrit

Answer: (A)

The main concept here is recognizing signs that indicate ongoing intra-abdominal hemorrhage after trauma. When bleeding continues, the body underperforms in perfusing tissues, and you’ll see a cascade of clues. Tachycardia with hypotension that doesn’t respond to fluids shows the heart trying to compensate for persistent blood loss, and a lack of adequate return to the circulation suggests the bleed isn’t controlled. Abdominal distension points to blood accumulating in the abdominal cavity (hemoperitoneum). A decreasing hematocrit confirms that red blood cells are being lost faster than they’re being replaced. Rising lactate signals tissue hypoperfusion and anaerobic metabolism, which worsens as shock progresses. A positive FAST test adds direct evidence of free intraperitoneal fluid, most likely blood, in the trauma setting. Together, these findings build a clear picture of ongoing intra-abdominal bleeding demanding urgent intervention. In contrast, normal vital signs with stable hematocrit imply there isn’t active bleed or perfusion failure at that moment. Hyperkalemia with a widened pulse pressure isn’t specific to intra-abdominal bleeding, and a combination of low lactate with normal hematocrit suggests adequate perfusion and no active hemorrhage.
