Hinkle Chapter 68: Management of Patients With Neurologic Trauma
The nurse in the neurologic ICU is caring for a client who sustained a severe brain injury. What cerebral perfusion pressure should the nurse maintain?
50 to 70 mm Hg to help control increased ICP
The earliest sign of serious impairment of brain circulation related to increased ICP is:
A change in LOC
What finding should the nurse expect in a patient with spinal shock?
Absence of reflexes along with flaccid extremities
This is an acute emergency and is seen in clients with a cervical or high thoracic spinal cord injury after the spinal shock subsides.
Autonomic dysreflexia
What are possible long-term complications of spinal cord injury?
Autonomic dysreflexia Respiratory infection
What are the components of the Cushing's Triad?
Bradycardia, hypertension, and Respiratory irregularities
When the nurse observes that the patient has extension and external rotation of the arms and wrists, and extension, plantar flexion, and internal rotation of the feet, she records the patient's posturing as:
Decerebrate
LOC can be assessed based on the criteria in the GCS, which include:
Eye opening, verbal response, and motor response
________ in the client with a TBI can be the result of damage to the hypothalamus, cerebral irritation from hemorrhage, or infection
Fever
What nursing diagnoses are appropriate for a client who has suffered a head injury
Ineffective airway clearance: Apply suction as indicated Disturbed sleep pattern: Provide back rubs to the client Interrupted family process: Encourage the family to join a support group
A GCS score of 13 to 15 is classified as:
Mild TBI
A GCS score of 9 to 12 is classified as:
Moderate TBI
What is an appropriate nursing intervention to monitor for early signs of diabetes insipidus?
Monitor I&O and take daily weights
This is the most common cause of SCI is
Motor vehicle crashes
What condition occurs when blood collects between the dura mater and arachnoid membrane?
Subdural hematoma
A client with spinal trauma tells the nurse she cannot cough. What nursing intervention should the nurse perform when a client with spinal trauma may not be able to cough?
Suction the Airway
The Monro-Kellie hypothesis refers to:
The dynamic equilibrium of cranial contents
What is a key component in planning care of a patient with an epidural hematoma?
The understanding that rapid neurologic deterioration occurs
What needs to reported for a patient who experienced a concussion?
Vomiting - indicates increasing ICP
What finding indicates increasing intracranial pressure (ICP) in the client who has sustained a head injury?
Widening Pulse Pressure
What are the risk factors for spinal cord injury (SCI)?
Young Age Alcohol and/or drug use Male Gender
To help prevent adverse effects of high doses methylprednisolone the nurse expects the physician to order:
famotidine
What should the nurse most encourage the caregiver of a tetraplegic to do to help maintain skin integrity?
regularly relieve pressure Protect from injury Keep clean and dry Avoid wrinkles in the bed Maintain a diet high in protein, vitamins, and calories to ensure minimal wasting of muscles and healthy skin
Symptoms progressively worsen in a client with an ______ subdural hematoma within the first 24 hours of the head injury
Acute
A type of neurogenic pain whereby clients experience pain in response to a normally painless stimulus
Allodynia
A "Battle sign" may indicate a basilar skull fracture in a patient who has sustained a head injury. What is a "battle sign"?
An area of bruising over the mastoid bone
Fluid leaking from the patient's ears is a probable sign of which type of skull fracture?
Basilar
For a patient with an SCI, why is it beneficial to administer oxygen to maintain a high partial pressure of oxygen (PaO2)?
Because hypoxemia can create or worsen a neurologic deficit of the spinal cord
A client with a spinal cord injury has full head and neck control when the injury is at which level?
C5
Results from a blow to the head that jars the brain
Concussion
Dual bruising can result if the force is strong enough to send the brain ricocheting to the opposite side of the skull, which is called a:
Contrecoup injury
This results in bruising, and sometimes, hemorrhage of superficial cerebral tissue
Contusions are
To assist in controlling ICP in clients with severe brain injury, the following are recommended:
Elevate the head of the bed as prescribed (gravity helps drain fluid) Maintain head/neck in neutral alignment (no twisting or flexing) Give sedation as ordered to prevent agitation Avoid noxious stimuli (scatter procedures so that client does not become overtired)
Bleeding between the inner skull and the dura, compressing the brain underneath
Epidural hematoma or extradural hematoma
This type of spinal nerve root compression involves the tissues surrounding the spinal cord
Extramedullary
To detect any CSF drainage, the nurse looks for a ________ sign, which is a blood stain surrounded by a clear or yellowish stain
Halo
What are characteristics of autonomic dysreflexia?
Hypertension Tachycardia Bradycardia Severe, pounding headache Flushed skin/Diaphoresis Nausea Nasal congestion
Posttraumatic seizures are classified as ______ (within 24 hours after injury), ______ (within 1 to 7 days after injury), or ______ (more than 7 days after injury)
Immediate, Early, Late
A client has sustained a traumatic brain injury. What is the priority nursing diagnosis for this client?
Ineffective Airway Clearance
A client is admitted with a cervical spine injury sustained during a diving accident. What is the priority nursing diagnosis?
Ineffective breathing pattern
bleeding in the brain or the cerebral tissue with displacement of surrounding structures
Intracerebral hemorrhage
This type of spinal nerve root compression involves the spinal cord
Intramedullary
What is the benefit of the halo device usage in a patient who has sustained a SCI?
It allows for stabilization of the cervical spine along with early ambulation.
An epidural hematoma is considered an extreme emergency; marked neurologic deficit or even respiratory arrest can occur within minutes. Treatment consists of:
Making openings through the skull (burr holes) to decrease intracranial pressure emergently, remove the clot, and control the bleeding.
A patient with a C7 spinal cord fracture informs the nurse, "My head is killing me!" The nurse assesses a blood pressure of 210/140 mm Hg, heart rate of 48 and observes diaphoresis on the face. What is the first action by the nurse?
Place the patient in a sitting position
This term refers to muscular hypertonicity in a weak muscle, with increased resistance to stretch
Spasticity
This is an acute complication of SCI
Spinal Shock
The nurse is caring for a client experiencing autonomic dysreflexia. Which of the following does the nurse recognize as the source of symptoms?
Sympathetic Nervous System
When the head is struck directly, the injury to the brain is called a:
Coup injury
When caring for a client who is post-intracranial surgery what is the most important parameter to monitor?
It is important to monitor the client's body temperature closely because hyperthermia increases brain metabolism, increasing the potential for brain damage
___________ injury results from the initial damage from the traumatic event.
Primary
What is the priority nursing diagnosis for client who is disoriented and restless after sustaining a concussion during a car accident?
Risk for injury
___________ injury results from inadequate delivery of nutrients and oxygen to the cells, usually due to cerebral edema and increased intracranial pressure.
Secondary
