For pelvic fractures NEVER

• A. Use a pelvic binder
• B. Forceful manual compression and pelvic rock of the pelvis to determine instability
• C. Monitor vitals
• D. Obtain imaging as needed

Answer: (B)

Testing instability of a suspected pelvic fracture with forceful manual compression or pelvic rocking is not performed. Manual manipulation can disrupt clots, worsen hemorrhage, and cause additional tissue or vascular injury, making bleeding harder to control. The appropriate approach is to stabilize the pelvis with a binder, monitor vital signs for signs of ongoing bleeding or shock, and obtain imaging as needed (pelvic X-ray or CT) to define the fracture pattern and help guide definitive management. The other actions—early pelvic stabilization, continuous monitoring, and imaging when indicated—are key parts of ATCN care, while forceful manipulation to assess instability is avoided because it can cause harm.
