MSII Prep U Ch. 68 Management of Patients With Neurologic Trauma

Which type of hematoma results from a skull fracture that causes a rupture or laceration of the middle meningeal artery?

Epidural An epidural hematoma can result from a skull fracture that causes a rupture or laceration of the middle meningeal artery. A subdural hematoma is a collection of blood between the dura and the brain. An intracerebral hemorrhage is bleeding into the substance of the brain. A DAI involves widespread damage to axons in the cerebral hemispheres, corpus callosum and brain stem.

Neurological level of spinal cord injury refers to which of the following?

The lowest level at which sensory and motor function is normal "Neurologic level" refers to the lowest level at which sensory and motor functions are normal. It is not the level of spinal cord transection, the best possible level of recovery, or the highest level at which sensory and motor function is normal

The nurse is caring for a patient in the emergency department with a diagnosed epidural hematoma. What procedure will the nurse prepare the patient for?

Burr holes 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.

After a motor vehicle crash, a client is admitted to the medical-surgical unit with a cervical collar in place. The cervical spinal X-rays haven't been read, so the nurse doesn't know whether the client has a cervical spinal injury. Until such an injury is ruled out, the nurse should restrict this client to which position? Flat Supine, with the head of the bed elevated 30 degrees Flat, except for logrolling as needed A head elevation of 90 degrees to prevent cerebral swelling

Flat, except for logrolling as needed When caring for the client with a possible cervical spinal injury who's wearing a cervical collar, the nurse must keep the client flat to decrease mobilization and prevent further injury to the spinal column. The client can be logrolled, if necessary, with the cervical collar on.

A client with quadriplegia is in spinal shock. What finding should the nurse expect?

Absence of reflexes along with flaccid extremities During the period immediately following a spinal cord injury, spinal shock occurs. In spinal shock, all reflexes are absent and the extremities are flaccid. When spinal shock subsides, the client will demonstrate positive Babinski's reflex, hyperreflexia, and spasticity of all four extremities.

At which level of cord injury does a patient have full head and neck control?

C5 At level C5, there is full head and neck control. At C1 there is little or no sensation or control of the head and neck. At C2 to C3 there is head and neck sensation and some neck control. At C4 there is good head and neck sensation and motor control.

A nurse is reviewing a CT scan of the brain, which states that the client has arterial bleeding with blood accumulation above the dura. Which of the following facts of the disease progression is essential to guide the nursing management of client care?

Monitoring is needed as rapid neurologic deterioration may occur. The nurse identifies that the CT scan suggests an epidural hematoma. A key component in planning care is the understanding that rapid neurologic deterioration occurs. Symptoms evolve quickly. A crash cart may be kept nearby, but this is not the key information. An intracerebral hematoma is bleeding within the brain, which is a different area of bleeding.

A client has sustained a traumatic brain injury, with involvement of the hypothalamus. The healthcare team is concerned about the complication of diabetes insipidus. Which of the following would be an appropriate nursing intervention to monitor for early signs of diabetes insipidus?

Record intake and output. A record of intake and output is maintained for the client with a traumatic brain injury, especially if the client has hypothalamic involvement and is at risk for the development of diabetes insipidus. Excessive output will alert the nurse to possible fluid imbalance early in the process.

A client who is disoriented and restless after sustaining a concussion during a car accident is admitted to the hospital. Which nursing diagnosis takes the highest priority in this client's care plan?

Risk for injury Because the client is disoriented and restless, the most important nursing diagnosis is Risk for injury. Although Disturbed sensory perception (visual), Dressing or grooming self-care deficit, and Impaired verbal communication may all be appropriate, they're secondary because they don't immediately affect the client's health or safety.

A nurse completes the Glasgow Coma Scale on a patient with traumatic brain injury (TBI). Her assessment results in a score of 6, which is interpreted as:

Severe TBI. A score of 13 to 15 is classified as mild TBI, 9 to 12 is moderate TBI, and 3 to 8 is severe TBI. A score of 3 indicates severe impairment of neurologic function, deep coma, brain death, or pharmacologic inhibition of the neurologic response; a score of 8 or less typically indicates an unconscious patient; a score of 15 indicates a fully alert and oriented patient.

Which of the following terms refers to muscular hypertonicity with increased resistance to stretch?

Spasticity Spasticity is often associated with weakness, increased deep tendon reflexes, and diminished superficial reflexes. Akathisia refers to a restless, an urgent need to move around, and agitation. Ataxia refers to impaired ability to coordinate movement. Myoclonus refers to spasm of a single muscle or group of muscles.

The nurse is caring for a patient immediately following a spinal cord injury (SCI). Which of the following is an acute complication of spinal cord injury?

Spinal shock Acute complications of SCI include spinal and neurogenic shock and deep-vein thrombosis (DVT). The spinal shock associated with SCI reflects a sudden depression of reflex activity in the spinal cord (areflexia) below the level of injury. Cardiogenic shock is not associated with SCI. Tetraplegia is paralysis of all extremities after a high cervical spine injury. Paraplegia occurs with injuries at the thoracic level. Autonomic dysreflexia is a long-term complication of spinal cord injury.

Which of the following conditions occurs when bleeding occurs between the dura mater and arachnoid membrane?

Subdural hematoma A subdural hematoma is bleeding between the dura mater and arachnoid membrane. Intracerebral hemorrhage is bleeding in the brain or the cerebral tissue with displacement of surrounding structures. An epidural hematoma is bleeding between the inner skull and the dura, compressing the brain underneath. An extradural hematoma is another name for an epidural hematoma.

Autonomic dysreflexia can occur with spinal cord injuries above which of the following levels?

T6 Any patient with a lesion above T6 segment is informed that autonomic dysreflexia can occur and that it may occur even years after the initial injury.

Which of the following is not a manifestation of Cushing's Triad?

Tachycardia Cushing's triad is manifested by bradycardia, hypertension, and bradypnea. Tachycardia is not a component of the triad.

A client with a spinal cord injury is to receive Lovenox (enoxaparin) 50 mg subcutaneously twice a day. The medication is supplied in vials containing 80 mg per 0.8 mL. How many mL will constitute the correct dose? Enter the correct number ONLY.

0.5 ml 50 mg/80 mg) X 0.8 mL = 0.5 mL.

A client with a spinal cord injury is to receive methylprednisolone sodium succinate 100 mg intravenously twice a day. The medication is supplied in vials containing 125 mg per 2 mL. How many mL will constitute the correct dose? Enter the correct number ONLY

1.6 ml (100 mg/125 mg) x 2 mL = 1.6 mL.

You are a neuro trauma nurse working in a neuro ICU. What would you know 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 Autonomic dysreflexia is an acute emergency and is seen in clients with a cervical or high thoracic spinal cord injury, usually after the spinal shock subsides. Tetraplegia results in the paralysis of all extremities when there is a high cervical spine injury. Paraplegia occurs with injuries at the thoracic level. Areflexia is a loss of sympathetic reflex activity below the level of injury within 30 to 60 minutes of a spinal injury.

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 Oxygen is administered to maintain a high partial pressure of arterial oxygen (PaO2) because hypoxemia can create or worsen a neurologic deficit of the spinal cord.

Which of the following is the earliest sign of increasing intracranial pressure (ICP)?

Change in level of consciousness (LOC) The earliest sign of increasing ICP is a change in LOC. Any changes in LOC should be reported immediately. Seizures, restlessness, and pupil changes may occur, but these are not the earliest signs.

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 which of the following?

Decerebrate Decerebrate posturing is the result of lesions at the midbrain and is more ominous than decorticate posturing. The described posturing results from cerebral trauma and is not normal. The patient has no motor function, is limp, and lacks motor tone with flaccid posturing. In decorticate posturing, the patient has flexion and internal rotation of the arms and wrists and extension, internal rotation, and plantar flexion of the feet.

A client has sustained a traumatic brain injury. Which of the following is the priority nursing diagnosis for this client?

Ineffective airway clearance related to brain injury Maintaining an airway is always the priority. All the other choices are appropriate nursing diagnoses for this client, but the priority is maintinence of the airway.

A patient comes to the emergency department with a large scalp laceration after being struck in the head with a glass bottle. After assessment of the patient, what does the nurse do before the physician sutures the wound?

Irrigates the wound to remove debris Scalp wounds are potential portals of entry for organisms that cause intracranial infections. Therefore, the area is irrigated before the laceration is sutured to remove foreign material and to reduce the risk for infection.

Which are characteristics of autonomic dysreflexia?

severe hypertension, slow heart rate, pounding headache, sweating Autonomic dysreflexia is an exaggerated sympathetic nervous system response. Hypertension, tachycardia, bradycardia, and flushed skin would occur.

A 24-year-old female rock climber is brought to the Emergency Department after a fall from the face of a rock. The young lady is admitted for observation after being diagnosed with a contusion to the brain. The client asks the nurse what having a contusion means. How should the nurse respond?

Contusions are bruising, and sometimes, hemorrhage of superficial cerebral tissue. Contusions result in bruising, and sometimes, hemorrhage of superficial cerebral tissue. When the head is struck directly, the injury to the brain is called a coup injury. 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. Edema develops at the site of or in areas opposite to the injury. A skull fracture can accompany a contusion. Therefore options B, C, and D are incorrect.

A client has sustained a traumatic brain injury with involvement of the hypothalamus. The nurse is concerned about the development of diabetes insipidus. Which of the following would be an appropriate nursing intervention to monitor for early signs of diabetes insipidus?

Take daily weights. A record of daily weights is maintained for the client with a traumatic brain injury, especially if the client has hypothalamic involvement and is at risk for the development of diabetes insipidus. A weight loss will alert the nurse to possible fluid imbalance early in the process.

The nurse working on the neurological unit is caring for a client with a basilar skull fracture. During assessment, the nurse expects to observe Battle's sign, which is a sign of basilar skill fracture. Which of the following correctly decribes Battle's sign?

Ecchymosis over the mastoid With fractures of the base of the skull, an area of ecchymosis (bruising) may be seen over the mastoid and is called Battle's sign. Basilar skull fractures are suspected when cerebrospinal fluid escapes from the ears or the nose.

The nurse reviews the physician's emergency department progress notes for the patient who has sustained a head injury and sees that the physician observed Battle's sign. The nurse knows that the physician observed which clinical manifestation?

An area of bruising over the mastoid bone Battle's sign may indicate a skull fracture. A bloodstain surrounded by a yellowish stain on the head dressing is referred to as a halo sign and is highly suggestive of a cerebrospinal fluid leak. Escape of CSF from the patient's ear is termed otorrhea. Escape of CSF from the patient's nose is termed rhinorrhea.

A patient sustained a head trauma in a diving accident and has a cerebral hemorrhage located within the brain. What type of hematoma is this classified as?

An intracerebral hematoma Intracerebral hemorrhage (hematoma) is bleeding within the brain, into the parenchyma of the brain. It is commonly seen in head injuries when force is exerted to the head over a small area (e.g., missile injuries, bullet wounds, stab injuries). A subdural hematoma (SDH) is a collection of blood between the dura and the brain, a space normally occupied by a thin cushion of cerebrospinal fluid. After a head injury, blood may collect in the epidural (extradural) space between the skull and the dura.

The nurse working on a neurological unit is mentoring a nursing student who asks about a client who has sustained primary and secondary brain injuries. The nurse correctly tells the student which of the following, related to the secondary injury?

It results from inadequate delivery of nutrients and oxygen to the cells. Secondary injury results from inadequate delivery of nutrients and oxygen to the cells, usually as a result of cerebral edema and increased intracranial pressure. Primary injury results from initial damage related to the traumatic event.

A patient with a concussion is discharged after the assessment. Which of the following instructions should the nurse give the patient's family?

Look for signs of increased intracranial pressure The nurse informs the family to monitor the patient closely for signs of IICP if findings are normal and the patient does not require hospitalization. The nurse looks for a halo sign to detect any CSF drainage.

The most important nursing priority of treatment for a patient with an altered LOC is to:

Maintain a clear airway to ensure adequate ventilation. The first priority of treatment for the patient with altered LOC is to obtain and maintain a patent airway. The patient may be orally or nasally intubated (unless basilar skull fracture or facial trauma is suspected), or a tracheostomy may be performed. Until the ability of the patient to breathe on his or her own is determined, a mechanical ventilator is used to maintain adequate oxygenation and ventilation.

The nurse is caring for a client who was discovered unconscious after falling off a ladder. The client is diagnosed with a concussion. All testing is normal, and discharge instructions are compiled. Which instructions have been compiled for the spouse?

Observe for any signs of behavioral changes. All of the options are typical for a client being discharged with a concussion. The instruction that is emphasized is to observe for any signs of behavior changes, which may indicate an increase in the client's intracranial pressure. A concussion results in diffuse or microscopic injury to the brain with symptoms that may evolve.

A client presents to the emergency department stating numbness and tingling occurring down the left leg into the left foot. When documenting the experience, which medical terminology would the nurse be most correct to report?

Paresthesia When a client reports numbness and tingling in an area, he is reporting a paresthesia. The nurse would document the experience as such or place the client's words in parentheses. The nurse would not make a medical diagnosis of sciatic nerve pain or herniation. The symptoms are not consistent with paralysis.

A client who has been severely beaten is admitted to the emergency department. The nurse suspects a basilar skull fracture after assessing:

raccoon's eyes and Battle sign. A basilar skull fracture commonly causes only periorbital ecchymosis (raccoon's eyes) and postmastoid ecchymosis (Battle sign); however, it sometimes also causes otorrhea, rhinorrhea, and loss of cranial nerve I (olfactory nerve) function. Nuchal rigidity and Kernig's sign are associated with meningitis. Motor loss in the legs that exceeds that in the arms suggests central cord syndrome. Pupillary changes are common in skull fractures with associated meningeal artery bleeding and uncal herniation.

A client in the intensive care unit (ICU) has a traumatic brain injury. The nurse must implement interventions to help control intracranial pressure (ICP). Which of the following are appropriate interventions to help control ICP?

Keep the client's neck in a neutral position (no flexing). 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, and avoid noxious stimuli (scatter procedures so that client does not become overtired).

Which of the following conditions occurs when there is bleeding between the dura mater and arachnoid membrane?

Subdural hematoma A subdural hematoma is bleeding between the dura mater and arachnoid membrane. Intracerebral hemorrhage is bleeding in the brain or the cerebral tissue with displacement of surrounding structures. An epidural hematoma is bleeding between the inner skull and the dura, compressing the brain underneath. An extradural hematoma is another name for an epidural hematoma.

The nurse working on a neurological unit is mentoring a nursing student who asks about a client who has sustained primary and secondary brain injuries. The nurse correctly tells the student which of the following, related to the secondary injury? It results from inadequate delivery of nutrients and oxygen to the cells. It results from initial damage to the brain from the traumatic event. It refers to the permanent deficits seen after the rehabilitation process. It refers to the difficulties suffered by the client and family related to the changes in the client.

It results from inadequate delivery of nutrients and oxygen to the cells. Secondary injury results from inadequate delivery of nutrients and oxygen to the cells, usually as a result of cerebral edema and increased intracranial pressure. Primary injury results from initial damage related to the traumatic event.

A patient was admitted to a rehabilitation unit for treatment of a spinal cord injury. The admitting diagnosis is central cord syndrome. During an admissions physical, the nurse expects to find:

Loss of motor power and sensation in the upper extremities. Characteristics of a central cord injury include motor deficits (in the upper extremities compared to the lower extremities; sensory loss varies but is more pronounced in the upper extremities); bowel/bladder dysfunction is variable, or function may be completely preserved.

The nurse in the emergency department is caring for a patient brought in by the rescue squad after falling from a second-story window. The nurse assesses ecchymosis over the mastoid and clear fluid from the ears. What type of skull fracture is this indicative of?

Basilar skull fracture A fracture of the base of the skull is referred to as a basilar skull fracture. Fractures of the base of the skull tend to traverse the paranasal sinus of the frontal bone or the middle ear located in the temporal bone. Therefore, they frequently produce hemorrhage from the nose, pharynx, or ears, and blood may appear under the conjunctiva. An area of ecchymosis (bruising) may be seen over the mastoid (Battle's sign). Basilar skull fractures are suspected when CSF escapes from the ears (CSF otorrhea) and the nose (CSF rhinorrhea).

A nurse is assisting with the clinical examination for determination of brain death for a client, related to potential organ donation. All 50 states in the United States recognize uniform criteria for brain death. The nurse is aware that the three cardinal signs of brain death on clinical examination are all of the following except:

Glasgow Coma Scale of 6 The three cardinal signs of brain death on clinical examination are coma, absence of brain stem reflexes, and apnea. The Glasgow Coma Scale is a tool for determining the client's level of consciousness. A score of 3 indicates a deep coma, and a score of 15 is normal.

A client in the surgical intensive care unit has skeletal tongs in place to stabilize a cervical fracture. Protocol dictates that pin care should be performed each shift. When providing pin care for the client, which finding should the nurse report to the physician?

A small amount of yellow drainage at the left pin insertion site The nurse should report the presence of yellow drainage, which indicates the presence of infection, at the left pin insertion site. Crust formation around the pin site is a natural response to the trauma caused by the pin insertion. Redness at the insertion site may be an early sign of infection; the nurse should continue to monitor the area, but this finding doesn't need to be reported to the physician. The client may experience pain at the pin insertion sites; therefore, the nurse should administer pain medications as ordered. It's necessary to notify the physician only if the pain medication is ineffective.

The ED nurse is receiving a patient-handoff report at the beginning of the nursing shift. The departing nurse notes a patient with a head injury has Battle's sign. The nurse will expect which of the following clinical manifestation?

An area of bruising over the mastoid bone Fractures of the base of the skull tend to traverse the paranasal sinus of the frontal bone or the middle ear located in the temporal bone Therefore, they frequently produce hemorrhage from the nose, pharynx, or ears, and blood may appear under the conjunctiva. An area of ecchymosis (bruising) may be seen over the mastoid (Battle's sign). Basilar skull fractures are suspected when CSF escapes from the ears (CSF otorrhea) and the nose (CSF rhinorrhea). Drainage of CSF is a serious problem, because meningeal infection can occur if organisms gain access to the cranial contents via the nose, ear, or sinus through a tear in the dura. A blood stain surrounded by a yellowish stain on the head dressing is referred to as a halo sign and is highly suggestive of a CSF leak.

A patient is admitted to the emergency room with a fractured skull sustained in a motorcycle accident. The nurse notes fluid leaking from the patient's ears. The nurse knows this is a probable sign of which type of skull fracture?

Basilar Basilar skull fractures are suspected when cerebrospinal fluid (CSF) escapes from the ears (CSF otorrhea) and/or the nose (CSF rhinorrhea).

When caring for a client who is post-intracranial surgery what is the most important parameter to monitor?

Body temperature It is important to monitor the client's body temperature closely because hyperthermia increases brain metabolism, increasing the potential for brain damage. Therefore, elevated temperature must be relieved with an antipyretic and other measures. Options A, B, and C are not the most important parameters to monitor.

At a certain point, the brain's ability to autoregulate becomes ineffective and decompensation (ischemia and infarction) begins. Which of the following are associated with Cushing's triad? Select all that apply.

Bradycardia Hypertension Bradypnea The bradycardia, hypertension, and bradypnea associated with this deterioration are known as Cushing's triad, a grave sign. At this point, herniation of the brainstem and occlusion of the cerebral blood flow occur if therapeutic intervention is not initiated immediately.

While riding a bicycle in a race, a patient fell into a ditch and sustained a head injury. Another cyclist found the patient lying unconscious in the ditch and called 911. What type of concussion does the patient most likely have?

Grade 3 concussion There are three grades of concussion or mild traumatic brain injury defined by the American Academy of Neurology when the injury is sports related (Ruff, Iverson, Barth, et al., 2009). A grade 1 concussion has symptoms of transient confusion, no loss of consciousness, and duration of mental status abnormalities on examination that resolve in less than 15 minutes. A grade 2 concussion also has symptoms of transient confusion and no loss of consciousness, but the concussion symptoms or mental status abnormalities on examination last more than 15 minutes. In a grade 3 concussion, there is any loss of consciousness lasting from seconds to minutes (Ruff et al., 2009).

The nurse working on a neurological unit is mentoring a nursing student. The student asks about a client who has sustained a primary and and secondary brain injury. The nurse correctly tells the student which of the following, related to the primary injury?

It results from initial damage to the brain from the traumatic event. The primary injury results from the initial damage from the traumatic event. The secondary injury results from inadequate delivery of nutrients and oxygen to the cells, usually due to cerebral edema and increased intracranial pressure.

A client with tetraplegia cannot do his own skin care. The nurse is teaching the caregiver about the importance of maintaining skin integrity. Which of the following will the nurse most encourage the caregiver to do?

Maintain a diet for the client that is high in protein, vitamins, and calories. To maintain healthy skin, the following interventions are necessary: regularly relieve pressure, protect from injury, keep clean and dry, avoid wrinkles in the bed, and maintain a diet high in protein, vitamins, and calories to ensure minimal wasting of muscles and healthy skin.

The nurse is caring for a patient with TBI (traumatic brain injury). The nurse notes the following clinical findings during the reassessment of the patient. Which of the following will cause the nurse the most concern?

Temperature increase from 98.0°F to 99.6°F Fever in the patient with a TBI can be the result of damage to the hypothalamus, cerebral irritation from hemorrhage, or infection. The nurse monitors the patient's temperature every 2 to 4 hours. If the temperature increases, efforts are made to identify the cause and to control it using acetaminophen and cooling blankets to maintain normothermia. The remaining clinical findings are within normal limits.

The nurse is admitting a client from the emergency department with a reported spinal cord injury. What device would the nurse expect to be used to provide correct vertebral alignment and to increase the space between the vertebrae in a client with spinal cord injury? Cervical collar Cast Traction with weights and pulleys Turning frame

Traction with weights and pulleys Traction with weights and pulleys is applied to provide correct vertebral alignment and to increase the space between the vertebrae. A cast and a cervical collar are used to immobilize the injured portion of the spine. A turning frame is used to change the client's position without altering the alignment of the spine.

While snowboarding, a fell and sustained a blow to the head, resulting in a loss of consciousness. The client regained consciousness within an hour after arrival at the ED, was admitted for 24-hour observation, and was discharged without neurologic impairment. What would the nurse expect this client's diagnosis to be?

concussion A concussion results from a blow to the head that jars the brain. It usually is a consequence of falling, striking the head against a hard surface such as a windshield, colliding with another person (e.g., between athletes), battering during boxing, or being a victim of violence. The force of the blow causes temporary neurologic impairment but no serious damage to cerebral tissue. There is generally complete recovery within a short time.

When planning care for a client with a head injury, which position should the nurse include in the care plan to enhance client outcomes?

30-degree head elevation For clients with increased intracranial pressure (ICP), the head of the bed should be elevated to 30 degrees to promote venous outflow. Trendelenburg's position is contraindicated because it can raise ICP. Flat or neutral positioning is indicated when elevating the head of the bed would increase the risk of neck injury or airway obstruction. A side-lying position isn't specifically a therapeutic treatment for increased ICP.

Which Glasgow Coma Scale score is indicative of a severe head injury?

7 A score of 8 or less is generally accepted as indicating a severe head injury.

The nurse is caring for a patient diagnosed with an acute subdural hematoma following a craniotomy. The nurse is preparing to administer an IV dose of dexamethasone (Decadron). The medication is available in a 20-mL IV bag and ordered to be infused over 15 minutes. At what rate (mL/hr) will the nurse set the infusion pump?

80 20/15 × 60 = 80 mL/hr

The earliest sign of serious impairment of brain circulation related to increased ICP is:

A change in consciousness. The earliest sign of increasing ICP is a change in the LOC. Any changes in LOC should be reported immediately.

The nurse is caring for a patient following an SCI who has a halo device in place. The patient is preparing for discharge. Which of the following statements made by the patient indicates the need for further instruction?

"I can apply powder under the liner to help with sweating." The areas around the four pin sites of a halo device are cleaned daily and observed for redness, drainage, and pain. The pins are observed for loosening, which may contribute to infection. If one of the pins becomes detached, the head is stabilized in a neutral position by one person while another notifies the neurosurgeon. The skin under the halo vest is inspected for excessive perspiration, redness, and skin blistering, especially on the bony prominences. The vest is opened at the sides to allow the torso to be washed. The liner of the vest should not become wet because dampness causes skin excoriation. The liner should be changed periodically to promote hygiene and good skin care. Powder is not used inside the vest because it may contribute to the development of pressure ulcers.

The nurse is caring for a patient with a head injury. The patient is experiencing CSF rhinorrhea. Which of the following orders should the nurse question?

Insertion of a nasogastric (NG) tube Patients with brain injury are assumed to be catabolic and nutritional support consultation should be considered as soon as the patient is admitted. Parenteral nutrition via a central line or enteral feedings administered via an NG or nasojejunal (NJ) feeding tube should be considered. If CSF rhinorrhea occurs, an oral feeding tube should be inserted instead of a nasal tube. Serial studies of blood and urine electrolytes and osmolality are done because head injuries may be accompanied by disorders of sodium regulation. Urine is tested regularly for acetone. An intervention to maintain skin integrity is getting the patient out of bed to a chair three times daily.

The nurse is caring for a patient in the neurologic ICU who sustained a severe brain injury. Which of the following nursing measures will the nurse implement to aid in controlling ICP?

Maintaining cerebral perfusion pressure from 50 to 70 mm Hg The nurse should maintain cerebral perfusion pressure from 50 to 70 mm Hg to aid in controlling increased ICP. Other measures include elevating the head of the bed as prescribed, maintaining the patient's head and neck in neutral alignment (no twisting or flexing the neck), initiating measures to prevent the Valsalva maneuver (e.g., stool softeners), maintaining body temperature within normal limits, administering O2 to maintain PaO2 greater than 90 mm Hg, maintaining fluid balance with normal saline solution, avoiding noxious stimuli (e.g., excessive suctioning, painful procedures), and administering sedation to reduce agitation. Maintain cerebral perfusion pressure from 50 to70 mm Hg. Alternative measures to restraints should be implemented, and stool softeners verses enemas should be used to avoid increasing ICP.

The nurse received the report from a previous shift. One of her clients was reported to have a history of basilar skull fracture with otorrhea. What assessment finding does the nurse anticipate?

The client has cerebral spinal fluid (CSF) leaking from the ear. Otorrhea means leakage of CSF from the ear. The client with a basilar skull fracture can create a pathway from the brain to the middle ear due to a tear in the dura. As a result, the client can have cerebral spinal fluid leak from the ear. The nurse may assess clear fluid in the ear canal. Ecchymosis and periorbital edema can be present as a manifestation of bruising from the head injury. An elevated temperature may occur from the head injury and is monitored closely. The client may have serous drainage from the nose especially immediately following the injury.
