- An amateur boxer sustained a powerful punch to the upper abdomen. 36 hours after the event, which of the following findings suggests pancreatic injury? Bowel sounds in the chest Serum lipase elevation Left shoulder pain Blood in the urine - answer-Serum lipase elevation
- The goals of damage control surgery in the trauma patient include each of the following EXCEPT restoration of normal physiology. repair of all traumatic injuries. early blood product transfusion. active hemorrhage control. - answer-repair of all traumatic injuries.
