Chapter 68

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)?

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.

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. 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.

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. Explanation: 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 Explanation: 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.

Which of the following types of hematoma results from venous bleeding with blood gradually accumulating in the space below the dura?

Subdural Explanation: A subdural hematoma results from venous bleeding, with blood gradually accumulating in the space below the dura. An epidural hematoma stems from arterial bleeding, usually from the middle meningeal artery, and blood accumulation above the dura. An intracerebral hematoma is bleeding within the brain that results from an open or closed head injury or from a cerebrovascular condition such as a ruptured cerebral aneurysm. A cerebral hematoma is bleeding within the skull.

While stopped at a stop sign, a patient's car was struck from behind by another vehicle. The patient sustained a cerebral contusion and was admitted to the hospital. During what time period after the injury will the effects of injury peak?

18 to 36 hours Explanation: Contusions are characterized by loss of consciousness associated with stupor and confusion. 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.

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

7 Explanation: A score between 3 and 8 is generally accepted as indicating a severe head injury.

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

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.

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 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).

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 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.

When assessing a client who has experienced a spinal injury, the nurse notes diaphragmatic breathing and loss of upper limb use and sensation. At what level does the nurse anticipate the injury has occurred?

C5 Explanation: The nurse should anticipate that the injury has occurred at level C5. Injuries above C3 result in the loss of spontaneous respiratory function. Clients with injuries at T6 and L1 retain some degree of upper limb use and sensation.

The nurse is offering suggestions regarding reproductive options to a husband and paraplegic wife. Which option is most helpful?

Conception is not impaired; the birth process is determined with the physician. Explanation: The nurse's role is to provide facts without inserting personal opinions. The fact is that the woman can conceive and bear children. Suggesting adoption, a surrogate, and sterilization is not appropriate. Providing information on that suggestion is appropriate.

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. 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 options B, C, and D are incorrect.

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 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 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 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.

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

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. Explanation: 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 client with a concussion is discharged after the assessment. Which instruction should the nurse give the client's family?

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. The nurse looks for a halo sign to detect any cerebrospinal fluid drainage.

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 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:

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.

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

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.

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 Explanation: 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 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?

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

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.

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. Explanation: 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 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. 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.

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 Explanation: 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.

The ED nurse is receiving a client handoff report at the beginning of the nursing shift. The departing nurse notes that the client with a head injury shows Battle sign. The incoming nurse expects which to observe clinical manifestation?

An area of bruising over the mastoid bone Explanation: 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 sign). Basilar skull fractures are suspected when cerebrospinal fluis (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 bloodstain 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 client has been admitted for observation after a closed head injury. There is clear fluid leaking from the client's nose. How would the nurse assess if this drainage is CSF?

Assess for a halo sign Explanation: Most clients are hospitalized for at least 24 hours after a significant head injury. The nurse examines the client to identify signs of head trauma and tests drainage from the nose or ear. To detect any CSF drainage, the nurse looks for a halo sign, which is a blood stain surrounded by a clear or yellowish stain. If drainage is present, the nurse allows it to flow freely onto porous gauze and avoids tightly plugging the orifice.

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

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.

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 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.

A client was hit in the head with a ball and knocked unconscious. Upon arrival at the emergency department and subsequent diagnostic tests, it was determined that the client suffered a subdural hematoma. The client is becoming increasingly symptomatic. How would the nurse expect this subdural hematoma to be classified?

acute Explanation: Subdural hematomas are classified as acute, subacute, and chronic according to the rate of neurologic changes. Symptoms progressively worsen in a client with an acute subdural hematoma within the first 24 hours of the head injury.

Which are possible long-term complications of spinal cord injury? Select all that apply.

autonomic dysreflexia respiratory infection Explanation: Autonomic dysreflexia and respiratory infection are long-term complications of spinal cord injury. Respiratory arrest and spinal shock (areflexia) are immediate complications of spinal cord injury.

Which condition occurs when blood collects between the dura mater and arachnoid membrane?

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.

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

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

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. 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.

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

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.
