Med Surge PrepU- Neurologic Dysfunction

Which medication classification is used preoperatively to decrease the risk of postoperative seizures?

Anticonvulsants Anticonvulsants are used to decrease the risk of postoperative seizures following cranial surgery. Diuretics, corticosteroids, and antianxiety medications may be used for the client with increased intracranial pressure.+

A client with increased intracranial pressure has a cerebral perfusion pressure (CPP) of 40 mm Hg. This CPP reading is considered

Low Normal cerebral perfusion pressure (CPP) is 70 to 100 mm Hg. A CPP of 40 mm Hg is low.

After a seizure, the nurse should place the patient in which of the following positions to prevent complications?

Side-lying, to facilitate drainage of oral secretions To prevent complications, the patient is placed in the side-lying position to facilitate drainage of oral secretions, and suctioning is performed, if needed, to maintain a patent airway and prevent aspiration.

Cerebral edema peaks at which time point after intracranial surgery?

24 hours Cerebral edema tends to peak 24 to 36 hours after surgery

A nurse assesses the patient's level of consciousness using the Glasgow Coma Scale. What score indicates severe impairment of neurologic function?

3 Each criterion in the Glasgow Coma Scale (eye opening, verbal response, and motor response) is rated on a scale from 3 to 15. A total score of 3 indicates severe impairment of neurologic function, brain death, or pharmacologic inhibition of the neurologic response. A score of 15 indicates that the patient is fully responsive.

Which phase of a migraine headache usually lasts less than an hour?

Aura The aura phase occurs in about 20% of clients who have migraines and may be characterized by focal neurological symptoms. The premonitory phase occurs hours to days before a migraine headache. The headache phase lasts from 4 to 72 hours. During the postdrome phase, clients may sleep for extended periods.

The nurse is educating a patient with a seizure disorder. What nutritional approach for seizure management would be beneficial for this patient?

High in protein and low in carbohydrate A dietary intervention, referred to as the ketogenic diet, may be helpful for control of seizures in some patients. This high-protein, low-carbohydrate, high-fat diet is most effective in children whose seizures have not been controlled with two antiseizure medications, but it is sometimes used for adults who have had poor seizure control (Mosek, Natour, Neufeld, et al., 2009).

Which method is used to help reduce intracranial pressure?

Using a cervical collar Use of a cervical collar promotes venous drainage and prevents jugular vein distortion, which can increase ICP. Slight elevation of the head is maintained to aid in venous drainage unless otherwise prescribed. Extreme rotation of the neck is avoided because compression or distortion of the jugular veins increases ICP. Extreme hip flexion is avoided because this position causes an increase in intra-abdominal pressure and intrathoracic pressure, which can produce a rise in ICP.

Which signs are manifestations of the Cushing triad?

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

The nurse is caring for a client with mid-to-late stage of an inoperable brain tumor. What teaching is important for the nurse to do with this client?

Explaining hospice care and services The nurse explains hospice care and services to clients with brain tumors that no longer are at a stage where they can be cured. Managing muscle weakness and offering family support groups are important, but explaining hospice is the best answer. Optimizing nutrition at this point is not a priority.

A nurse is preparing to administer an antiseizure medication to a client. Which of the following is an appropriate antiseizure medication?

Lamictal Lamictal is an antiseizure medication. Its packaging was recently changed in an attempt to reduce medication errors, because this medication has been confused with Lamisil (an antifungal), labetalol (an antihypertensive), and Lomotil (an antidiarrheal).

The nurse is caring for a patient with increased ICP. As the pressure rises, what osmotic diuretic does the nurse prepare to administer?

Mannitol If signs and symptoms of increased ICP occur, efforts to decrease the ICP are initiated: alignment of the head in a neutral position without flexion to promote venous drainage, elevation of the head of the bed to 30 degrees (when prescribed), administration of mannitol (an osmotic diuretic), and possible administration of pharmacologic paralyzing agents.

When educating a patient about the use of antiseizure medication, what should the nurse inform the patient is a result of long-term use of the medication in women?

Osteoporosis Because of bone loss associated with the long-term use of antiseizure medications, patients receiving antiseizure agents should be assessed for low bone mass and osteoporosis. They should be instructed about strategies to reduce their risks of osteoporosis (AANN, 2009).

What is one of the earliest signs of increased ICP?

decreased level of consciousness (LOC) Headache is a symptom of increased ICP, but decreasing LOC is one of the earliest signs of increased ICP. Cushing's triad occurs late in increased ICP. If untreated, increasing ICP will lead to coma.

A client weighing 132 lb is brought to the emergency department in status epilepticus. The physician asks the nurse to prepare diazepam 0.25 mg/kg. How many milligrams will be given to this client?

15 Step 1: 2.2 lb / 1 kg = 132 lb / X kg 132 lb = 2.2 X 60 kg = X Step 2: 1 kg / 0.25 mg = 60 kg / X mg 15 mg = X

The critical care nurse is caring for a client with bacterial meningitis. The client has developed cerebral vasculitis and increased ICP. What neurologic sequelae might this client develop?

Damage to the optic nerve Neurologic sequelae in survivors include damage to the cranial nerves that facilitate vision and hearing. Sequelae to meningitis do not include damage to the vagal nerve, the olfactory nerve or the facial nerve.

A nurse is caring for a female client following a motor vehicle accident resulting in paraplegia. The client is ready for discharge to home with her husband, who states, "I'm scared to carry her because I'm afraid I'll either hurt my back or drop her." A nurse identifies a need for discharge teaching of the husband in regard to:

ergonomic principles and body mechanics. The husband's statement indicates a need for teaching in regard to client mobility and transfer techniques. Although urinary elimination, nutrition, and pain are components of care for clients with paraplegia, education about ergonomic principles and body mechanics is most appropriate at this time based on the husband's statement.

The spouse of a client with terminal brain cancer asks the nurse about hospice. Which statement by the nurse best describes hospice care?

"Clients and families are the focus of hospice care." The most important component of hospice care is the focus that is placed on the care of the client as well as the family. Hospice does take a team approach and coordinates care through the hospice physician, but these are not the focus. Not all hospice clients wish to die at home.

The nurse is taking care of a client with a history of headaches. The nurse takes measures to reduce headaches and administer medications. Which appropriate nursing interventions may be provided by the nurse to such a client?

Apply warm or cool cloths to the forehead or back of the neck Applying warm or cool cloths to the forehead or back of the neck and massaging the back relaxes muscles and provides warmth to promote vasodilation. These measures are aimed at reducing the occurrence of headaches in the client.

Which is the earliest sign of increasing intracranial pressure?

Change in level of consciousness The earliest sign of increasing intracranial pressure (ICP) is a change in level of consciousness. Other manifestations of increasing ICP are vomiting, headache, and posturing.

The nurse is caring for a client with Guillain-Barré syndrome. Which assessment finding would indicate the need for oral suctioning?

Increased pulse rate, adventitious breath sounds An increased pulse rate above baseline with adventitious breath sounds indicate compromised respirations and signal a need for airway clearance. A decrease in pulse rate is not indicative of airway obstruction. An increase of pulse rate with slight elevation of respirations (16 breaths/minute) is not significant for suctioning unless findings suggest otherwise.

A client with neurologic infection develops cerebral edema from syndrome of inappropriate antidiuretic hormone (SIADH). Which is an important nursing action for this client?

Restricting fluid intake and hydration Fluid restriction may be necessary if the client develops cerebral edema and hypervolemia from SIADH. Antipyretics are administered to clients who develop hyperthermia. In addition, it is important to maintain adequate hydration in such clients. A client with neurologic infection should be given tracheal suctioning and hyperoxygenation only when the respiratory distress develops.

An older client complains of a constant headache. A physical examination shows papilledema. What may the symptoms indicate in this client?

Brain tumor The incidence of brain tumor decreases with age. Headache and papilledema are less common symptoms of a brain tumor in the older adult. Symptoms of epilepsy include fits and spasms, while symptoms of trigeminal neuralgia would be pain in the jaws or facial muscles. Hypostatic pneumonia develops due to immobility or prolonged bed rest in older clients.

A nurse is working on a neurological unit with a nursing student who asks the difference between primary and secondary headaches. The nurse's correct response will include which of the following statements?

"A secondary headache is associated with an organic cause, such as a brain tumor." A secondary headache is a symptom associated with an organic cause, such as a brain tumor or an aneurysm. A primary headache is one for which no organic cause can be identified. These types include migraine, tension, and cluster headaches. Secondary headaches can be located in all areas of the head.

A client with newly diagnosed seizures asks about stigma associated with epilepsy. The nurse will respond with which of the following statements?

"Many people with developmental disabilities resulting from neurologic damage also have epilepsy." Many people who have developmental disabilities because of serious neurologic damage also have epilepsy. Epilepsy is not associated with intellectual level. It is not synonymous with intellectual disability or illness.

A nurse is caring for a client with a brain tumor and increased intracranial pressure (ICP). Which intervention should the nurse include in the care plan to reduce ICP?

Administer stool softeners. Stool softeners reduce the risk of straining during a bowel movement, which can increase ICP by raising intrathoracic pressure and interfering with venous return. Coughing also increases ICP. Keeping the head in a midline position and avoiding extreme neck flexion prevents obstruction of venous outflow from the brain. Sensory stimulation and noxious stimuli can increase ICP

Which positions is used to help reduce intracranial pressure (ICP)?

Avoiding flexion of the neck with use of a cervical collar Use of a cervical collar promotes venous drainage and prevents jugular vein distortion, which can increase ICP. Slight elevation of the head is maintained to aid in venous drainage unless otherwise prescribed. Extreme rotation of the neck is avoided because compression or distortion of the jugular veins increases ICP. Extreme hip flexion is avoided because this position causes an increase in intra-abdominal pressure and intrathoracic pressure, which can produce a rise in ICP.

A nurse caring for a patient with head trauma will be monitoring the patient for Cushing's triad. What will the nurse recognize as the symptoms associated with Cushing's triad? Select all that apply.

Bradycardia Bradypnea Hypertension At a certain point as intracranial pressure increases due to an injury, the brain's ability to autoregulate becomes ineffective and decompensation (ischemia and infarction) begins. When this occurs, the patient exhibits significant changes in mental status and vital signs. The bradycardia, hypertension, and bradypnea associated with this deterioration are known as Cushing's triad, which is a grave sign.

When performing a postoperative assessment on a client who has undergone surgery to manage increased intracranial pressure (ICP), a nurse notes an ICP reading of 0 mm Hg. Which action should the nurse perform first?

Check the equipment. A reading of 0 mm Hg indicates equipment malfunction. The nurse should check the equipment and report problems. Normal and stable ICP values are less than 15 mm Hg. Some pressure is always present in the cranial vault. The nurse shouldn't contact the physician to review the care plan at this time. The nurse needs to complete the assessment of the client and equipment before making a report to the physician.

A nurse is working in the neurologic intensive care unit and admits from the emergency department a patient with an inoperable brain tumor. Upon entering the room, the nurse observes that the patient is positioned like the person in part B of the accompanying image. Which posturing is the patient exhibiting?

Decerebrate An inappropriate or nonpurposeful response is random and aimless. Posturing may be decorticate or decerebrate. Decorticate posture is the flexion and internal rotation of forearms and hands. Decerebrate posture is extension and external rotation. Flaccidity is the absence of motor response; tonic clonic movements are seen with seizures.

The nurse is caring for a patient postoperatively after intracranial surgery for the treatment of a subdural hematoma. The nurse observes an increase in the patient's blood pressure from the baseline and a decrease in the heart rate from 86 to 54. The patient has crackles in the bases of the lungs. What does the nurse suspect is occurring?

Increased ICP Increased ICP and bleeding are life threatening to the patient who has undergone intracranial surgery. An increase in blood pressure and decrease in pulse with respiratory failure may indicate increased ICP.

When obtaining the vital signs of a client with multiple traumatic injuries, a nurse detects bradycardia, bradypnea, and systolic hypertension. The nurse must notify the physician immediately because these findings may reflect which complication?

Increased intracranial pressure (ICP) When ICP increases, Cushing triad may develop, which involves decreased heart and respiratory rates and increased systolic blood pressure. Shock typically causes tachycardia, tachypnea, and hypotension. In encephalitis, the temperature rises and the heart and respiratory rates may increase from the effects of fever on the metabolic rate. (If the client doesn't maintain adequate hydration, hypotension may occur.) Status epilepticus causes unceasing seizures, not changes in vital signs.

A nurse working on a medical-surgical floor walks into a patient's room to find the patient with an altered level of consciousness (LOC). Which of the following nursing diagnoses would be the first priority for the plan of care?

Ineffective airway clearance related to altered LOC The most important consideration in managing the patient with altered LOC is to establish an adequate airway and ensure ventilation.

What does the nurse recognize as the earliest sign of serious impairment of brain circulation related to increasing ICP?

Lethargy and stupor As ICP increases, the patient becomes stuporous, reacting only to loud or painful stimuli. At this stage, serious impairment of brain circulation is probably taking place, and immediate intervention is required.

A nurse is assessing a patient's urinary output as an indicator of diabetes insipidus. The nurse knows that an hourly output of what volume over 2 hours may be a positive indicator?

More than 200 mL/h For patients undergoing dehydrating procedures, vital signs, including blood pressure, must be monitored to assess fluid volume status. An indwelling urinary catheter is inserted to permit assessment of renal function and fluid status. During the acute phase, urine output is monitored hourly. An output greater than 200 mL per hour for 2 consecutive hours may indicate the onset of diabetes insipidus (Hickey, 2009).

A patient is admitted to the hospital for management of an extrapyramidal disorder. Included in the physician's admitting orders are the medications levodopa, benztropine, and selegiline. The nurse knows that most likely, the client has a diagnosis of:

Parkinson's disease. Although antiparkinson drugs are used in some clients with Huntington's disease, these drugs are most commonly used in the medical management of Parkinson's disease. The listed medications are not used to treat a seizure disorder. The listed medications are not used to treat MS.

A client is receiving hypothermic treatment for uncontrolled fever related to increased intracranial pressure (ICP). Which assessment finding requires immediate intervention?

Shivering Shivering can increase intracranial pressure by increasing vasoconstriction and circulating catecholamines. Shivering also increases oxygen consumption. A capillary refill of 2 seconds, urine output of 100mL/hr, and cool, dry skin are expected findings

When the nurse observes that the client has extension and external rotation of the arms and wrists and extension, plantar flexion, and internal rotation of the feet, she records the client's posture as

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 client has no motor function, is limp, and lacks motor tone with flaccid posturing. In decorticate posturing the client has flexion and internal rotation of the arms and wrists and extension, internal rotation, and plantar flexion of the feet.

To meet the sensory needs of a client with viral meningitis, the nurse should:

minimize exposure to bright lights and noise. Photophobia and hypersensitivity to environmental stimuli are the common clinical manifestations of meningeal irritation and infection. Therefore, the nurse should provide a calm environment with less stressful stimuli. Physical activity may worsen symptoms; therefore, physical activity should be reduced. Family members do not need to be avoided. People diagnosed with viral meningitis should be instructed to thoroughly wash hands frequently.

A nurse working in the neurologic intensive care unit admits from the emergency department a patient with an inoperable brain tumor. Upon entering the room, the nurse observes that the patient is positioned like part B of the accompanying image. Based on this initial observation, what would the nurse predict about this patient's prognosis?

poor An inappropriate or nonpurposeful response is random and aimless. Posturing may be decorticate or decerebrate. Decerebrate posturing indicates deeper and more severe dysfunction than does decorticate posturing; it implies brain pathology, which is a poor prognostic sign. Decorticate posture is the flexion and internal rotation of forearms and hands. Decerebrate posture is extension and external rotation. Flaccidity is the absence of motor response and the most severe neurologic impairment.

A nurse is assessing a client who has been in a motor vehicle collision. The client directly and accurately answers questions. The nurse notes a contusion to the client's forehead; the client reports a headache. Assessing the client's pupils, what reaction would confirm increasing intracranial pressure?

unequal response In increased ICP, the pupil response is unequal. One pupil responds more sluggishly than the other or becomes fixed and dilated.

A nurse is monitoring a client for increasing intracranial pressure (ICP). Early signs of increased ICP include:

diminished responsiveness. Usually, diminished responsiveness is the first sign of increasing ICP. Pupillary changes occur later. Increased ICP causes systolic blood pressure to rise. Temperature changes vary and may not occur even with a severe decrease in responsiveness.

A nurse is providing education about migraine headaches to a community group. The cause of migraines has not been clearly demonstrated, but is related to vascular disturbances. A member of the group asks about familial tendencies. The nurse's correct reply will be which of the following?

"There is a strong familial tendency." Migraine headaches have a strong familial tendency. Migraines are primary headaches, not secondary headaches.

Which nursing interventions might need to be considered in a care plan for a client with advanced multiple sclerosis? Select all that apply.

Ensure access to a language board when communicating with the client. Establish a voiding time schedule. Encourage the client to walk with feet wide apart. Language assistive devices may be needed if communication is severely affected. Occasional bladder incontinence may lead to total incontinence. A voiding time schedule will allow the client greater independence. If motor dysfunction causes problems of incoordination and clumsiness, the patient is at risk for falling. As the disease progresses, nutritional deficiencies may develop. Weight should be assessed to ensure that there is no significant weight loss.

The nurse is aware that burr holes may be used in neurosurgical procedures. Which of the following is a reason why a neurosurgeon may choose to create a burr hole in a patient?

Aspiration of a brain abscess Burr holes may be used in neurosurgical procedures to make a bone flap in the skull, to aspirate a brain abscess, or to evacuate a hematoma.

A client is admitted to an acute care facility after an episode of status epilepticus. After the client is stabilized, which factor is most beneficial in determining the potential cause of the episode?

Compliance with the prescribed medication regimen The most common cause of status epilepticus is sudden withdraw of anticonvulsant therapy. The type of medication prescribed, the client's stress level, and weight change don't contribute to this condition.

A nurse is working in the neurologic intensive care unit and admits from the emergency department a patient with a severe head injury. Upon entering the room, the nurse observes that the patient is positioned like part A of the accompanying image. Which posturing is the patient exhibiting?

Decorticate An inappropriate or nonpurposeful response is random and aimless. Posturing may be decorticate or decerebrate. Decorticate posture is the flexion and internal rotation of forearms and hands. Decerebrate posture is extension and external rotation. Flaccidity is the absence of motor response; tonic clonic movements are seen with seizures.

The nurse is caring for a patient with an altered LOC. What is the first priority of treatment for this patient?

Maintenance of a patent airway The first priority of treatment for the patient with altered LOC is to obtain and maintain a patent airway.

A client with a brain tumor is complaining of a headache upon awakening. Which nursing action would the nurse take first?

Elevate the head of the bed. The first action would be to elevate the head of the bed to promote venous drainage of blood and cerebral spinal fluid (CSF). Then, a neurological assessment would be completed to determine if any other assessment findings are significant of increasing intracranial pressure (ICP). The administering of routine ordered drugs is not a priority, and narcotic analgesics would be avoided in clients with ICP issues.

A client with epilepsy is having a seizure. During the active seizure phase, the nurse should:

place the client on his side, remove dangerous objects, and protect his head. During the active seizure phase, the nurse should initiate precautions by placing the client on his side, removing dangerous objects, and protecting his head from injury. A bite block should never be inserted during the active seizure phase. Insertion can break the teeth and lead to aspiration. Placing the client on his back and holding down the arms could cause injury to the client and the nurse.

The nurse is caring for a client immediately after supratentorial intracranial surgery. The nurse performs the appropriate action by placing the patient in the

supine position with the head slightly elevated. After surgery, the nurse should place the client in either a supine position with the head slightly elevated or a side-lying position on the unaffected side. The dorsal recumbent, Trendelenburg, and prone positions can increase intracranial pressure.

A client is transferred to the intensive care unit after evacuation of a subdural hematoma. Which nursing intervention reduces the client's risk of increased intracranial pressure (ICP)?

Administering a stool softener as ordered To prevent the client from straining at stool, which may cause a Valsalva maneuver that increases ICP, the nurse should institute a regular bowel program that includes use of a stool softener. For a client at risk for increased ICP, the nurse should prevent, not encourage, oral fluid intake and should elevate the head of the bed only 30 degrees. Suctioning, indicated for a client with lung congestion, isn't necessary for this client.

Which of the following assessment findings would indicate an increasing intracranial pressure (ICP) in a client with head trauma? Select all that apply

Elevated systolic blood pressure Wide pulse pressure Elevated systolic blood pressure with widening pulse pressure is consistent with Cushing's triad, which occurs late in increasing ICP. Other signs of Cushing's triad include bradycardia and irregular breathing. Stiff neck is not a symptom associated with ICP. Generalized pain is not significant with ICP unless related to complaint of headache (especially upon awakening). Glasgow Coma Scale of 15 and brisk pupil response are normal findings.

A nurse is continually monitoring a client with a traumatic brain injury for signs of increasing intracranial pressure. The cranial vault contains brain tissue, blood, and cerebrospinal fluid; an increase in any of the components causes a change in the volume of the others. This hypothesis is called which of the following?

Monro-Kellie The Monro-Kellie hypothesis states that, because of the limited space for expansion in the skull, an increase in any one of its components causes a change in the volume of the others. Cushing's response is seen when cerbral blood flow decreases significantly. Systolic blood pressure increases, pulse pressure widens, and heart rate slows. The Dawn phenomenon is related to high blood glucose levels in the morning in clients with diabetes. Hasimoto's disease is related to the thyroid gland.

A client whose physical findings suggest a hyperpituitary condition undergoes an extensive diagnostic workup. Test results reveal a pituitary tumor, which necessitates a transsphenoidal hypophysectomy. The evening before the surgery, the nurse reviews preoperative and postoperative instructions given to the client earlier. Which postoperative instruction should the nurse emphasize?

"You must avoid coughing, sneezing, and blowing your nose." After a transsphenoidal hypophysectomy, the client must refrain from coughing, sneezing, and blowing the nose for several days to avoid disturbing the surgical graft used to close the wound. The head of the bed must be elevated, not kept flat, to prevent tension or pressure on the suture line. Within 24 hours after a hypophysectomy, transient diabetes insipidus commonly occurs; this calls for increased, not restricted, fluid intake. Visual, not auditory, changes are a potential complication of hypophysectomy.
