The patient was riding in a car that hit a tree. The head hit the windshield (coup) and then the brain rebounded within the skull toward the opposite side (contrecoup). For which type of traumatic brain injury should the nurse plan care for this patient?
1. acceleration–deceleration
2. rotational
3. contact
4. stationary
Correct Answer: 1
Acceleration–deceleration injury (linear injury) occurs when the head hits an object and the brain rebounds within the skull. Rotational injury occurs when the brain rotates within the skull and hits bony buttresses in the cranial vault. Contact phenomenon injury occurs when the head is hit by a moving object, such as a swinging bat. Stationary is not a type of injury.
