Study Notes
Head Injury: Etiology and Pathophysiology
- Head trauma primarily refers to craniocerebral trauma, marked by altered consciousness, including brief changes.
- It ranks as the second most common cause of neurologic injuries, being the leading cause of death for individuals aged 1 to 35.
- Historical causes include motor vehicle collisions and falls, but firearm-related deaths from head injuries have increased.
- Traumatic brain injury (TBI) is widespread and the leading cause of trauma-related fatalities in individuals under 45 years.
- Highest TBI incidences are in children under 4 and individuals aged 15 to 19; timely treatment influences survival.
Craniocerebral Trauma
- Can involve injuries to the scalp, skull, and brain tissues, ranging from minor wounds to severe concussions and fractures.
- Seriousness of head injury does not always correlate with visible damage; severe injuries can result in cerebral edema, sensory/motor deficits, and increased intracranial pressure (ICP).
- Injuries may result from direct trauma (impact to head) or indirect trauma (tension strains).
- Acceleration-deceleration injuries lead to bruising or contusions in key brain areas like the occipital and frontal lobes.
Clinical Manifestations of Head Injuries
- Head injuries can be open (due to skull fractures) or closed (concussions, contusions, lacerations).
- Open head injuries’ severity depends on the impact’s velocity, mass, shape, and direction.
- Closed head injuries may result in significant bleeding, especially with scalp lacerations.
- Hemorrhages can occur in various areas, such as scalp, epidural, subdural, intracerebral, and intraventricular locations.
- Epidural hematomas from arterial bleeding require immediate attention if lethargy or unconsciousness develops after regaining consciousness.
- Subdural hematomas form more slowly and can develop in patients who were previously alert.
Assessment of Head Injuries
- Subjective data: patient’s understanding of the injury, headaches, nausea, loss of consciousness, and bleeding history.
- Objective data: level of consciousness, respiratory status, pupil size/reaction, orientation, and vital signs monitoring.
- Presence of Battle’s sign indicates a possible skull fracture.
Diagnostic Tests and Medical Management
- Key diagnostic tools: CT, MRI, and PET scans for soft tissue evaluation.
- Immediate care focuses on life-support measures and maintaining normal body functions.
- Important interventions include maintaining a patent airway, ensuring oxygenation, and handling cervical spine injuries.
- Medications include mannitol and dexamethasone for managing cerebral edema and ICP, alongside anticonvulsants if necessary.
Nursing Interventions
- Monitor for signs of cerebrospinal fluid (CSF) leakage from ears/nose; do not attempt to clean or blow the nose if drainage occurs.
- Educate patients about complications to watch for post-injury like increased drowsiness or behavioral changes.
- Memory aids can facilitate patient orientation during recovery.
Prognosis for Head Injuries
- Outcomes can be unpredictable; damage extent does not always correlate with surgical or CT findings.
- Minor injuries may lead to lasting issues, including personality changes and increased susceptibility to further injury.
Spinal Cord Trauma: Etiology and Pathophysiology
- Spinal cord injuries, commonly from accidents, lead to serious disabilities or death.
- The vertebral column protects the spinal cord; injuries can involve fractures, compression, or dislocation.
- Complete cord injuries result in total loss of movement below the injury site; incomplete injuries vary in symptoms.
- Tetraplegia affects cervical segments, while paraplegia is confined to thoracic, lumbar, or sacral areas.
Clinical Manifestations of Spinal Cord Injuries
- Initial flaccid paralysis and loss of reflexes below the injury level occur; systemic functions may also be impaired.
- Complications, like autonomic dysreflexia, manifest in patients with injuries at the sixth thoracic vertebra or higher, characterized by high blood pressure and other symptoms.
- Dyspnea, unusual sensations, pain, and loss of consciousness should be assessed.
Diagnostic Tests and Medical Management for Spinal Cord Injuries
- Radiographs detect vertebral fractures; spinal taps or myelograms assess cord integrity.
- Immediate care focuses on realigning the vertebral column, potentially using immobilization, traction, or surgical decompression.
- High-dose methylprednisolone may be administered within 8 hours of the injury.
Nursing Interventions for Spinal Cord Injuries
- Care aims to restore structural integrity and prevent complications, including skin issues and contractures.
- It is crucial to maintain skin integrity, mobilize patients early, and implement bladder/bowel training to minimize infection risk.
- Monitor and educate patients about autonomic dysreflexia and sexual health post-injury.
Prognosis for Spinal Cord Injuries
- Complete spinal cord injuries lead to minimal chances of functional recovery, while incomplete injuries may allow for adaptations enabling satisfying lives despite limitations.### Assessment and Evaluation in Nervous System Disorders
- Disorders of the nervous system can lead to physical and cognitive challenges requiring tailored care.
- Continuous assessment of the patient’s learning readiness is crucial in providing effective care.
Evaluation Process
- Success of interventions should be evaluated both during and after care to adapt to the patient's changing condition.
- Care plans must be flexible; modifications are necessary when new symptoms, like confusion, arise post-operation.
- Ongoing evaluation aims to determine if specific outcomes have been achieved, aligned with pre-established goals.
Evaluation Goals and Measures
-
Goal 1: Infection-Free Status
- Evaluative Measures: Monitor for increased temperature, urinary frequency, erythema at incision sites, elevated white blood cell counts, or confusion.
-
Goal 2: Alertness and Orientation
- Evaluative Measures: Engage the patient with orientation questions and observe their participation in conversations and care tasks.
NCLEX Type Questions and Answers
-
A safety scenario involving a young man with a head injury emphasizes redirection as the first action to manage potential aggressive behavior. Medication is secondary and less preferred initially.
-
In another case with a spinal cord injury patient presenting with high blood pressure and associated symptoms, placing the patient in a sitting position is prioritized to lower blood pressure.
-
For rehabilitation potential in spinal cord injury patients, identifying the level of injury is important. The patient with a level of injury at L4 has the greatest chance for independent ambulation with aids.
-
Ambulation with long leg braces during rehab is linked to injuries at levels L1-2, indicating a moderate recovery potential.
Case Scenarios for Nursing Action
-
A calm redirection can effectively manage agitation in a resident with a history of poor judgment resulting from a head injury, rather than immediate medication or increased observation.
-
Properly addressing hypotension in spinal cord injury patients involves quick assessment for bladder distention or impaction and appropriate positioning. Following emergency protocols is critical for unstable cases.
