Study Notes
Nervous System Overview
- Coordination of balance and body movement is managed by the cerebellum.
- The peripheral nervous system includes 31 pairs of spinal nerves and 12 pairs of cranial nerves.
- The autonomic nervous system regulates involuntary body functions.
Cranium and Brain Facts
- Eighty percent of the cranium is occupied by brain tissue.
- Seven vertebrae make up the cervical spine.
Scalp Injuries and Fractures
- Lacerations to the scalp may indicate deeper, more serious injuries.
- Linear skull fractures are least likely to show outward deformities or signs.
Amnesia and Consciousness
- Retrograde amnesia occurs when a patient cannot recall events preceding a head injury.
- Monitoring the level of consciousness is crucial in head injury care.
Patient Assessment and Management
- When assessing for spinal injuries, determine if strength in all extremities is equal.
- A GCS score of 14 is given to a patient who opens her eyes spontaneously, is confused, and obeys commands.
- Establishing an adequate airway is the most critical immediate treatment for head injury patients.
Managing Bleeding and Immobility
- To control bleeding from scalp lacerations with a suspected skull fracture, avoid excessive pressure when applying a bandage.
- The EMT at the head is responsible for all patient movements when placing onto a long backboard.
Cervical Collar Application
- A cervical collar must be used in addition to manual immobilization, not as a replacement.
