The nurse is caring for a client following a spinal cord injury who has a halo device in place. The client is preparing for discharge. Which statement by the client indicates the need for further instruction? "I will change the vest liner periodically." "If a pin becomes detached, I'll notify the surgeon." "I can apply powder under the liner to help with sweating." "I'll check under the liner for blisters and redness."

"I can apply powder under the liner to help with sweating." Explanation: Powder is not used inside the vest because it may contribute to the development of pressure ulcers. 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 can cause skin excoriation. The liner should be changed periodically to promote hygiene and good skin care.

When planning care for a client with a head injury, which position should the nurse include in the care plan to enhance client outcomes? Trendelenburg's 30-degree head elevation Flat Side-lying

30-degree head elevation Explanation: 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.

The earliest sign of serious impairment of brain circulation related to increased ICP is: A bounding pulse. Bradycardia. Hypertension. A change in consciousness.

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

A client with quadriplegia is in spinal shock. What finding should the nurse expect? Absence of reflexes along with flaccid extremities Positive Babinski's reflex along with spastic extremities Hyperreflexia along with spastic extremities Spasticity of all four extremities

Absence of reflexes along with flaccid extremities Explanation: 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.

A client is admitted to the hospital after sustaining a closed head injury in a skiing accident. The physician ordered neurologic assessments to be performed every 2 hours. The client's neurologic assessments have been unchanged since admission, and the client is complaining of a headache. Which intervention by the nurse is best? Administer codeine 30 mg by mouth as ordered and continue neurologic assessments as ordered. Assess the client's neurologic status for subtle changes, administer acetaminophen, and then reassess the client in 30 minutes. Reassure the client that a headache is expected and will go away without treatment. Notify the physician; a headache is an early sign of worsening neurologic status.

Assess the client's neurologic status for subtle changes, administer acetaminophen, and then reassess the client in 30 minutes. Explanation: Headache is common after a head injury. Therefore, the nurse should administer acetaminophen to try to manage the client's pain without causing sedation. The nurse should then reassess the client in 30 minutes to note the effectiveness of the pain medication. Administering codeine, an opioid, could cause sedation that may mask changes in the client's neurologic status. Although a headache is expected, the client should receive treatment to alleviate pain. The nurse should notify the physician if the client's neurologic status changes or if treatment doesn't relieve the headache.

A client with a T4 level spinal cord injury (SCI) is complaining of a severe headache. The nurse notes profuse diaphoresis of the client's forehead and scalp. Which of the following does the nurse suspect? Autonomic dysreflexia Thrombophlebitis Orthostatic hypotension Spinal shock

Autonomic dysreflexia Explanation: Autonomic dysreflexia occurs only after spinal shock has resolved. It is characterized by a severe, pounding headache, marked hypertension, diaphoresis, nausea, nasal congestion, and bradycardia. It occurs only with SCIs above T6 and is a hypertensive emergency. It is not related to thrombophlebitis.

The client has been brought to the emergency department by their caregiver. The caregiver says that she found the client diaphoretic, nauseated, flushed and complaining of a pounding headache when she came on shift. What are these symptoms indicative of? Concussion Autonomic dysreflexia Spinal shock Contusion

Autonomic dysreflexia Explanation: Characteristics of this acute emergency are as follows: Severe hypertension; Slow heart rate; Pounding headache; Nausea; Blurred vision; Flushed skin; Sweating; Goosebumps (erection of pilomotor muscles in the skin); Nasal stuffiness; and Anxiety. The symptoms in the scenario are not symptoms or concussion, spinal shock, or contusion.

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? Simple Comminuted Depressed Basilar

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

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? Occipital skull fracture Temporal skull fracture Frontal skull fracture Basilar skull fracture

Basilar skull fracture Explanation: 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).

For a patient with an SCI, why is it beneficial to administer oxygen to maintain a high partial pressure of oxygen (PaO2)? So that the patient will not have a respiratory arrest Because hypoxemia can create or worsen a neurologic deficit of the spinal cord To increase cerebral perfusion pressure To prevent secondary brain injury

Because hypoxemia can create or worsen a neurologic deficit of the spinal cord Explanation: 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.

When caring for a client who is post-intracranial surgery what is the most important parameter to monitor? Extreme thirst Intake and output Nutritional status Body temperature

Body temperature Explanation: 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. Extreme thirst, intake and output, and nutritional status 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 Hypotension Tachycardia

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.

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? Hypophysectomy Application of Halo traction Burr holes Insertion of Crutchfield tongs

Burr holes Explanation: 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 client with a spinal cord injury has full head and neck control when the injury is at which level? C1 C2 to C3 C4 C5

C5 Explanation: At level C5, the client retains full head and neck control. At C1 the client has little or no sensation or control of the head and neck. At C2 to C3 the client feels head and neck sensation and has some neck control. At C4 the client has good head and neck sensation and motor control.

At which of the following spinal cord injury levels does the patient have full head and neck control? C5 C4 C3 C2

C5 Explanation: At the level of C5, the patient should have full head and neck control, shoulder strength, and elbow flexion. At C4 injury, the patient will have good head and neck sensation and motor control, some shoulder elevation, and diaphragm movement. At C2 to C3, the patient will have head and neck sensation, some neck control, and can be independent of mechanical ventilation for short periods of time.

Which type of brain injury is characterized by a loss of consciousness associated with stupor and confusion? Concussion Contusion Diffuse axonal injury Intracranial hemorrhage

Contusion Explanation: Other characteristics can include tissue alteration and neurologic deficit without hematoma formation, alteration in consciousness without localizing signs, and hemorrhage into the tissue that varies in size and is surrounded by edema. The effects of injury (hemorrhage and edema) peak after about 18 to 36 hours. A concussion is a temporary loss of neurologic function with no apparent structural damage. A diffuse axonal injury involves widespread damage to the axons in the cerebral hemispheres, corpus callosum, and brainstem. An intracranial hemorrhage is a collection of blood that develops within the cranial vault.

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 are deep brain injuries. Contusions are microscopic brain injuries. Contusions occur when the brain is jarred and bounces off the skull on the opposite side from the blow.

Contusions are bruising, and sometimes, hemorrhage of superficial cerebral tissue. Explanation: 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 the other options are incorrect.

Insertion of a nasogastric (NG) tube Explanation: Clients with brain injury are assumed to be catabolic, and nutritional support consultation should be considered as soon as the client is admitted. Parenteral nutrition via a central line or enteral feedings administered via an NG or nasojejunal feeding tube should be considered. If cerebrospinal fluid 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 client out of bed to a chair three times daily. Reference:

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 Normal Flaccid Decorticate

Decerebrate Explanation: 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.

The nurse working on the neurological unit is caring for a client with a basilar skull fracture. During the assessment, the nurse expects to observe Battle's sign, which is a sign of basilar skull fracture. Which of the following correctly describes Battle's sign? Ecchymosis over the mastoid Bruising under the eyes Drainage of cerebrospinal fluid from the nose Drainage of cerebrospinal fluid from the ears

Ecchymosis over the mastoid Explanation: 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.

Level of consciousness (LOC) can be assessed based on criteria in the Glasgow Coma Scale (GCS). Which of the following indicators are assessed in the GCS? Select all that apply. Eye opening Verbal response Motor response Intelligence Muscle strength

Eye opening Verbal response Motor response LOC can be assessed based on the criteria in the GCS, which include eye opening, verbal response, and motor response. The patient's responses are rated on a scale from 3 to 15. Intelligence and muscle strength are not measured in the GCS.

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: Coma Absence of brain stem reflexes Apnea Glasgow Coma Scale of 6

Glasgow Coma Scale of 6 Explanation: 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.

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 1 concussion Grade 2 concussion Grade 3 concussion Grade 4 concussion

Grade 3 concussion Explanation: 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).

A client has sustained a traumatic brain injury. Which of the following is the priority nursing diagnosis for this client? Deficient fluid balance related to decreased level of consciousness and hormonal dysfunction Ineffective cerebral tissue perfusion related to increased intracranial pressure Disturbed thought processes related to brain injury Ineffective airway clearance related to brain injury

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

A client is admitted with a cervical spine injury sustained during a diving accident. When planning this client's care, the nurse should assign highest priority to which nursing diagnosis? Impaired physical mobility Ineffective breathing pattern Disturbed sensory perception (tactile) Dressing or grooming self-care deficit

Ineffective breathing pattern Explanation: Because a cervical spine injury can cause respiratory distress, the nurse should take immediate action to maintain a patent airway and provide adequate oxygenation. Impaired physical mobility, Disturbed sensory perception (tactile), and Dressing or grooming self-care deficit may be appropriate for a client with a spinal cord injury — particularly during the course of recovery — but they don't take precedence over a diagnosis of Ineffective breathing pattern.

The nurse is caring for a client with a head injury. The client is experiencing CSF rhinorrhea. Which order should the nurse question? Insertion of a nasogastric (NG) tube Urine testing for acetone Serum sodium concentration testing Out of bed to the chair three times a day

A patient was body surfing in the ocean and sustained a cervical spinal cord fracture. A halo traction device was applied. How does the patient benefit from the application of the halo device? It is the only device that can be applied for stabilization of a spinal fracture. It allows for stabilization of the cervical spine along with early ambulation. It is less bulky and traumatizing for the patient to use. The patient can remove it as needed.

It allows for stabilization of the cervical spine along with early ambulation. Explanation: Halo devices provide immobilization of the cervical spine while allowing early ambulation.

A client with a concussion is discharged after the assessment. Which instruction should the nurse give the client's family? Have the client avoid physical exertion Emphasize complete bed rest Look for signs of increased intracranial pressure Look for a halo sign

Look for signs of increased intracranial pressure Explanation: The nurse informs the family to monitor the client closely for signs of increased intracranial pressure if findings are normal and the client does not require hospitalization. Signs of increased intracranial pressure include headache, blurred vision, vomiting, and lack of energy or sleepiness. The nurse looks for a halo sign to detect any cerebrospinal fluid drainage.

A client with weakness and tingling in both legs is admitted to the medical-surgical unit with a tentative diagnosis of Guillain-Barré syndrome. On admission, which assessment is most important for this client? Lung auscultation and measurement of vital capacity and tidal volume Evaluation for signs and symptoms of increased intracranial pressure (ICP) Evaluation of pain and discomfort Evaluation of nutritional status and metabolic state

Lung auscultation and measurement of vital capacity and tidal volume Explanation: In Guillain-Barré syndrome, polyneuritis commonly causes weakness and paralysis, which may ascend to the trunk and involve the respiratory muscles. Lung auscultation and measurement of vital capacity, tidal volume, and negative inspiratory force are crucial in detecting and preventing respiratory failure — the most serious complication of polyneuritis. A peripheral nerve disorder, polyneuritis doesn't cause increased ICP. Although the nurse must evaluate the client for pain and discomfort and must assess the nutritional status and metabolic state, these aren't priorities.

The most important nursing priority of treatment for a patient with an altered LOC is to: Stabilize the blood pressure and heart rate to ensure adequate perfusion of the brain. Prevent dehydration and renal failure by inserting an IV line for fluids and medications. Maintain a clear airway to ensure adequate ventilation. Position the patient to prevent injury and ensure dignity.

Maintain a clear airway to ensure adequate ventilation. Explanation: 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 in the neurologic ICU is caring for a client who sustained a severe brain injury. Which nursing measures will the nurse implement to help control intracranial pressure (ICP)? Position the client in the supine position Maintain cerebral perfusion pressure from 50 to 70 mm Hg Restrain the client, as indicated Administer enemas, as needed

Maintain cerebral perfusion pressure from 50 to 70 mm Hg Explanation: The nurse should maintain cerebral perfusion pressure from 50 to 70 mm Hg to help control increased ICP. Other measures include elevating the head of the bed as prescribed, maintaining the client'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.

Pressure ulcers may begin within hours of an acute spinal cord injury (SCI) and may cause delay of rehabilitation, adding to the cost of hospitalization. The most effective approach is prevention. Which of the following nursing interventions will most protect the client against pressure ulcers? Continuous use of an indwelling catheter Meticulous cleanliness Avoidance of all lotions and lubricants Allowing the client to choose the position of comfort

Meticulous cleanliness Explanation: Meticulous cleanliness is the best choice for preventing pressure ulcers. A continuous indwelling catheter is not conducive to preventing pressure ulcers. Pressure-sensitive areas should be kept well lubricated with lotion. The client does not know the best positioning techniques for prevention of skin breakdown. The nurse and client together should decide how to best position the body.

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? Symptoms will evolve over a period of 1 week. Monitoring is needed as rapid neurologic deterioration may occur. The crash cart with defibrillator is kept nearby. Bleeding continues into the intracerebral area.

Monitoring is needed as rapid neurologic deterioration may occur. Explanation: 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.

Which nursing intervention can prevent a client from experiencing autonomic dysreflexia? Administering zolpidem tartrate (Ambien) Assessing laboratory test results as ordered Placing the client in Trendelenburg's position Monitoring the patency of an indwelling urinary catheter

Monitoring the patency of an indwelling urinary catheter Explanation: A full bladder can precipitate autonomic dysreflexia, the nurse should monitor the patency of an indwelling urinary catheter to prevent its occlusion, which could result in a full bladder. Administering zolpidem tartrate, assessing laboratory values, and placing the client in Trendelenburg's position can't prevent autonomic dysreflexia.

The nurse is discussing spinal cord injury (SCI) at a health fair at a local high school. The nurse relays that the most common cause of SCI is Falls Sports-related injuries Motor vehicle crashes Acts of violence

Motor vehicle crashes Explanation: The most common causes of SCIs are motor vehicle crashes (46%), falls (22%), violence (16%), and sports (12%). Males account for 80% of clients with SCI. An estimated 50% to 70% of SCIs occur in those aged 15 to 35 years.

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? Sciatic nerve pain Herniation Paresthesia Paralysis

Paresthesia Explanation: When a client reports numbness and tingling in an area, the client 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 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. Call the physician. Assess the patient for a full bladder. Assess the patient for a fecal impaction.

Place the patient in a sitting position. Explanation: Autonomic dysreflexia, also known as autonomic hyperreflexia, is an acute life-threatening emergency that occurs as a result of exaggerated autonomic responses to stimuli that are harmless in normal people. It occurs only after spinal shock has resolved. This syndrome is characterized by a severe, pounding headache with paroxysmal hypertension, profuse diaphoresis (most often of the forehead), nausea, nasal congestion, and bradycardia. It occurs among patients with cord lesions above T6 (the sympathetic visceral outflow level) after spinal shock has subsided (Bader & Littlejohns, 2010). The patient is placed immediately in a sitting position to lower blood pressure.

Autonomic dysreflexia is an acute emergency that occurs with spinal cord injury as a result of exaggerated autonomic responses to stimuli. Which of the following is the initial nursing intervention to treat this condition? Examine the skin for any area of pressure or irritation. Examine the rectum for a fecal mass. Empty the bladder immediately. Raise the head of the bed and place the patient in a sitting position.

Raise the head of the bed and place the patient in a sitting position. Explanation: The head of the bed is raised and the patient is placed immediately in a sitting position to lower blood pressure. Assessment of body systems is done after the emergency has been addressed.

Elevated ICP is most commonly associated with head injury. Which of the following are clinical signs of increased ICP that a nurse should evaluate? Select all that apply. Lowered systolic blood pressure Respiratory irregularities Slow bounding pulse Increased cerebral perfusion Widened pulse pressure

Respiratory irregularities Slow bounding pulse Widened pulse pressure In the early stages of cerebral ischemia, the vasomotor centers are stimulated and the systemic pressure rises to maintain cerebral blood flow. This is typically accompanied by a slow, bounding pulse and respiratory irregularities. These changes in blood pressure, pulse, and respiration are important clinically because they suggest increased ICP. A sympathetically mediated response causes an increase in the systolic blood pressure, with a widening of the pulse pressure and cardiac slowing

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? Disturbed sensory perception (visual) Dressing or grooming self-care deficit Impaired verbal communication Risk for injury

Risk for injury Explanation: 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: Mild TBI. Moderate TBI. Severe TBI. Brain death.

Severe TBI. Explanation: 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 term refers to muscular hypertonicity in a weak muscle, with increased resistance to stretch? Akathisia Spasticity Ataxia Myoclonus

Spasticity Explanation: Spasticity is often associated with weakness, increased deep tendon reflexes, and diminished superficial reflexes. Akathisia refers to restlessness, 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 client immediately following a spinal cord injury (SCI). Which is an acute complication of SCI? Cardiogenic shock Tetraplegia Spinal shock Paraplegia

Spinal shock Explanation: 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 SCI.

Which condition occurs when blood collects between the dura mater and arachnoid membrane? Intracerebral hemorrhage Epidural hematoma Extradural hematoma Subdural hematoma

Subdural hematoma Explanation: A subdural hematoma is a collection of blood between the dura mater and the brain, a space normally occupied by a thin cushion of fluid. 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.

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? Administer oxygen as prescribed. Use mechanical ventilation. Let the airway stay as it currently is. Suction the airway.

Suction the airway. Explanation: Suctioning the airway helps remove secretions. An artificial airway increases the production of respiratory secretions. To prevent hypoxemia, the client may need more oxygen than is available in the room air. An endotracheal tube provides an airway from the nose or mouth to an area above the mainstem bronchi. Mechanical ventilation provides a means to regulate the respiratory rate, volume of air, and percentage of oxygen when a client fails to breathe independently.

Autonomic dysreflexia can occur with spinal cord injuries above which of the following levels? T6 S2 L4 T10

T6 Explanation: 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.

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. Reposition the client frequently. Assess for pupillary response frequently. Assess vital signs frequently.

Take daily weights. Explanation: 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 is caring for a client with traumatic brain injury (TBI). Which clinical finding, observed during the reassessment of the client, causes the nurse the most concern? Temperature increase from 98.0°F to 99.6°F Urinary output increase from 40 to 55 mL/hr Heart rate decrease from 100 to 90 bpm Pulse oximetry decrease from 99% to 97% room air

Temperature increase from 98.0°F to 99.6°F Explanation: Fever in the client with a TBI can be the result of damage to the hypothalamus, cerebral irritation from hemorrhage, or infection. The nurse monitors the client'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 other clinical findings are within normal limits.

The nurse learns a client 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. The client has ecchymosis in the periorbital region. The client has an elevated temperature. The client has serous drainage from the nose.

The client has cerebral spinal fluid (CSF) leaking from the ear. Explanation: 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.

The nurse is planning to provide education about prevention in the community YMCA due to the increase in numbers of spinal cord injuries (SCIs). What predominant risk factors does the nurse understand will have to be addressed? Select all that apply. Young age Male gender Older adult Substance abuse Low-income community

The predominant risk factors for SCI include young age, male gender, and alcohol and drug use.

predominant risk factors for spinal cord injury/SCI include

The predominant risk factors for SCI include young age, male gender, and alcohol and drug use. The frequency with which these risk factors are associated with SCI emphasizes the importance of primary prevention.

Which signs are considered cardinal signs of brain death? Select all that apply. Absence of brainstem reflexes No brain waves Apnea Coma

The three cardinal signs of brain death on clinical examination are coma, the absence of brainstem reflexes, and apnea. Adjunctive tests, such as cerebral blood flow studies, electroencephalography, transcranial Doppler, and brainstem auditory-evoked potential, are often used to confirm brain death.

Which finding indicates increasing intracranial pressure (ICP) in the client who has sustained a head injury? Increased pulse Increased respirations Widened pulse pressure Decreased body temperature

Widened pulse pressure Explanation: Signs of increasing ICP include slowing of the heart rate (bradycardia), increasing systolic blood pressure, and widening pulse pressure (Cushing reflex). As brain compression increases, respirations decrease or become erratic, blood pressure may decrease, and the pulse slows further. This is an ominous development, as is a rapid fluctuation of vital signs. Temperature is maintained at less than 38°C (100.4°F). Tachycardia and arterial hypotension may indicate that bleeding is occurring elsewhere in the body.

Which finding indicates increasing intracranial pressure (ICP) in the client who has sustained a head injury? Increased pulse Increased respirations Widened pulse pressure Decreased body temperature

The office nurse is reviewing an 80-year-old female client's reports related to the onset of a severe headache, rated at 9 out of 10 on the pain scale, with recent onset. The client denies any visual changes. During a prior visit to the office a few months ago, the client had reported a ground-level fall as a result of falling off a chair and hitting the back of their head. The client had been taken to the emergency department, where imaging was performed with negative results. Complete the following sentence by choosing from the lists of options. The nurse anticipates that the client has developed Select...chronic subdural hematomaacute subdural hematomastrokeSelect... and that Select...computed tomography (CT) imaging of the brainelectrocardiogram (ECG)coagulation profileSelect...will be ordered.

chronic subdural hematoma and that computed tomography (CT) imaging of the brain will be ordered. This client has had a prior head trauma with a negative imaging scan. Prior head trauma can lead to the development of a chronic subdural hematoma, which presents with symptoms such as severe headache, mental deterioration, focal neurologic changes, personality changes, and/or symptoms that the client is having a stroke. There is no indication that the client had follow-up imaging based on the prior head trauma, which should be included in protocol management of head injuries. Prior head trauma can lead to the development of a chronic subdural hematoma. Based on the clinical presentation of a severe headache, this is the most likely clinical diagnosis. Based on the clinical presentation, follow-up imaging is indicated to confirm the presence of a chronic subdural hematoma, which can occur following a recent head trauma. Because the head trauma occurred a few months ago, an acute finding would have presented earlier, at the time of injury. The differential diagnosis of chronic subdural hematoma includes a stroke but there is insufficient clinical evidence to support this finding. An electrocardiogram (ECG) is not indicated at this time because there is no provided clinical evidence of any cardiac abnormalities. Coagulation studies are not indicated at this time because the priority is to obtain an imaging study.

The nurse has documented a client diagnosed with a head injury as having a Glasgow Coma Scale (GCS) score of 7. This score is generally interpreted as coma. minimally responsive. least responsive. most responsive.

coma. Explanation: The GCS is a tool for assessing a client's response to stimuli. A score of 7 or less is generally interpreted as a coma. The lowest score is 3 (least responsive/deep coma); the highest is 15 (most responsive). A GCS between 3 and 8 is generally accepted as indicating a severe head injury. No category is termed "least" responsive.

Which are characteristics of autonomic dysreflexia? severe hypertension, slow heart rate, pounding headache, sweating severe hypotension, tachycardia, nausea, flushed skin severe hypertension, tachycardia, blurred vision, dry skin severe hypotension, slow heart rate, anxiety, dry skin

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

A nurse is caring for a 16-year-old adolescent with a head injury resulting from a fight after a high school football game. A physician has intubated the client and written orders to wean him from sedation therapy. A nurse needs further assessment data to determine whether: she'll have to apply restraints to prevent the client from dislodging the endotracheal (ET) tube. nutritional protocol will be effective after the client sedation therapy is tapered. to continue IV administration of other scheduled medications. payment status will change if the client isn't sedated.

she'll have to apply restraints to prevent the client from dislodging the endotracheal (ET) tube. Explanation: When the client isn't sedated, he may make attempts to remove the ET tube without realizing what he's doing. The nurse needs to obtain information to determine whether it's necessary to request an order for restraints. The nurse doesn't need to obtain additional data to determine if the nutritional protocol will continue to reflect the client's needs because this aspect of care won't change. The client doesn't require additional assessments to continue I.V. administration of medications. I.V. medication clearly needs to continue because the client is intubated. The staff nurse doesn't need to monitor payment status because client sedation shouldn't affect payment status.

A client has been diagnosed with a concussion and is to be released from the emergency department. The nurse teaches the family or friends who will be caring for the client to contact the physician or return to the ED if the client reports a headache. reports generalized weakness. sleeps for short periods of time. vomits.

vomits. Explanation: Vomiting is a sign of increasing intracranial pressure and should be reported immediately. In general, the finding of headache in a client with a concussion is an expected abnormal observation. However, a severe headache, weakness of one side of the body, and difficulty in waking the client should be reported or treated immediately.
