Ans- hemo-static agents What is a preventable cause of secondary brain injury? Ans- systemic hypoxia You're called to treat a patient who was knocked unconscious when he slipped and fell on a wet floor striking his head. It is now several hours later and he is awake but confused, does not recall the incident, and is vomiting with a headache. What injury is he most likely to have suffered? Ans- concussion What findings would indicate the need for immobilization when using a selective spinal immobilization protocol? Ans- pain or tenderness along the spine What patient should be treated first in a blast-related situation involving multiple patients? Ans- a 30- year-old female with altered level of consciousness and decreased capillary refill Excessive fluid resuscitation of the trauma patient can result in, what? Ans- increased blood loss When should the secondary survey be accomplished?
