Quiz :what are the signs/symptoms of spinal injury? - √Answer :neurologic
function above the injury is intact and function below the injury is absent or

Quiz :what are the (3) types of blast injuries? - √Answer :Primary injuries are

structural collapse; and
quaternary injuries, by all other forces
Quiz :what 3 collisions are involved with an MVA? - √Answer :1. vehicle collides

Quiz :what is the munro-kellie doctrine? - √Answer :1. The total intracranial
volume if fixed because of the inelastic nature of the skull
2. Inside the skull is the brain, blood & CSF
3. If ICP is increased (via haematoma, swelling or tumour) the skull cannot
expand to accommodate this
4. As a result some other structure must be forced out
5. First the CSF & Blood are forced out
6. The only way out is through the foramen magnum
7. Once the ability to force out CSF & blood has been exhausted, the ICP rises
rapidly & the next structure to be forced out of the vault is the brain
8. One of the first parts of the brain to be forced out is the medulla oblongata
causing an alteration in respirations
Quiz :what is major trauma? - √Answer :any trauma that requires p1 transport
