During abdominal trauma management, which finding is part of ongoing monitoring?

• A. Urine output
• B. Hair color
• C. Shoe size
• D. Eye movement

Answer: (A)

In abdominal trauma management, ongoing monitoring focuses on perfusion and organ function to catch deterioration early. Urine output is a direct indicator of kidney perfusion and overall circulating volume; a decrease suggests hypovolemia or ongoing bleeding and helps guide fluid or blood resuscitation decisions. This makes urine output the best choice for continuous assessment during care. Hair color, shoe size, and eye movement don’t provide reliable or actionable information about current physiologic status in this context, so they aren’t used for ongoing monitoring in acute abdominal trauma.
