chap 66-68
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. Explanation: 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.
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?
Correct response: "A secondary headache is associated with an organic cause, such as a brain tumor." Explanation: 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 quadriplegia is in spinal shock. What finding should the nurse expect?
Correct response: 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.
Which of the following, if left untreated, can lead to an ischemic stroke?
Correct response: Atrial fibrillation Explanation: Atrial fibrillation is the most frequently diagnosed arrhythmia in the United States. If left untreated, it can lead to an ischemic stroke. Cerebral hemorrhage, arteriovenous malformation, and cerebral hemorrhage can lead to a hemorrhagic stroke. Cerebral aneurysm, arteriovenous malformations, and ruptured cerebral arteries can lead to hemorrhagic stroke.
A client suffered a closed head injury in a motor vehicle collision, and an ICP monitor was inserted. In the occurrence of increased ICP, what physiologic function contributes to the increase in intracranial pressure?
Correct response: vasodilation Explanation: Hypotension and hypoxia lead to vasodilation, which contributes to increased ICP, compressing blood vessels and leading to cerebral ischemia. As ICP continues to rise, autoregulatory mechanisms can become compromised; hypotension and hypoxia lead to vasodilation, which contributes to increased ICP.
Which signs are manifestations of the Cushing triad? Select all that apply.
Correct response: Bradycardia Hypertension Bradypnea Explanation: Cushing triad is manifested by bradycardia, hypertension, and bradypnea. Tachycardia is not a component of the triad.
A client is receiving intravenous (IV) mannitol to prevent increased intracranial pressure. The order is for mannitol 1.5 grams per kg of body weight IV now. The client weighs 143 lbs (65 kg). How many grams will the nurse administer to the client? Enter the correct number in tenths
Explanation: 143 lbs/2.2 = 65 kg. 65 kg x 1.5 = 97.5 grams.
A nurse is monitoring a client for increasing intracranial pressure (ICP). Early signs of increased ICP include:
diminished responsiveness. Explanation: 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.
During a class on stroke, a junior nursing student asks what the clinical manifestations of stroke are. What would be the instructor's best answer?
Explanation: Clinical manifestations following a stroke are highly variable and depend on the area of the cerebral cortex and the affected hemisphere, the degree of blockage (total, partial), and the presence or absence of adequate collateral circulation. (Collateral circulation is circulation formed by smaller blood vessels branching off from or near larger occluded vessels.) Clinical manifestations of a stroke do not depend on the cardiovascular health of the client or how quickly the clot can be dissolved. Clinical manifestations of a stroke are not "general" but individual.
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? Correct response:
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 with a spinal cord injury has full head and neck control when the injury is at which level?
Correct response: 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.
A client has been diagnosed as having global aphasia. The nurse recognizes that the client will be unable to do perform which action?
Correct response: Form understandable words and comprehend spoken words Explanation: Global aphasia is a combination of expressive and receptive aphasia and presents a tremendous challenge to the nurse to communicate effectively with the client. In receptive and expressive aphasia, the client is unable to form words that are understandable. The client who is unable to speak at all is referred to as mute.
The nurse is caring for a patient having a hemorrhagic stroke. What position in the bed will the nurse maintain this patient?
Correct response: Semi-Fowler's Explanation: The head of the bed is elevated 15 to 30 degrees (semi-Fowler's position) to promote venous drainage and decrease intracranial pressure.
A 30-year-old was diagnosed with amyotrophic lateral sclerosis (ALS). Which statement by the client would indicate a need for more teaching from the nurse?
Correct response: "My children are at greater risk to develop this disease." Explanation: There is no known cause for ALS, and no reason to suspect genetic inheritance. ALS usually begins with muscle weakness of the arms and progresses. The client is encouraged to remain active for as long as possible to prevent respiratory complications.
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?
Correct response: 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).
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?
Correct response: Decorticate Explanation: 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 nursing instructor is teaching about hematomas to a pre-nursing pathophysiology class. What would the nursing instructor describe as an arterial bleed with rapid neurologic deterioration?
Correct response: Epidural hematoma Explanation: An epidural hematoma stems from arterial bleeding, usually from the middle meningeal artery, and blood accumulation above the dura. It is characterized by rapidly progressive neurologic deterioration.
A client is receiving an IV infusion of mannitol (Osmitrol) after undergoing intracranial surgery to remove a brain tumor. To confirm that this drug is producing its therapeutic effect, the nurse should consider which finding most significant?
Correct response: Increased urine output Explanation: The therapeutic effect of mannitol is diuresis, which is confirmed by an increased urine output. A decreased LOC and elevated blood pressure may indicate lack of therapeutic effectiveness. A decreased heart rate doesn't indicate that mannitol is effective.
Which is the initial diagnostic test for a stroke?
Correct response: Noncontrast computed tomography Explanation: The initial diagnostic test for a stroke is nonconstrast computed tomography performed emergently to determine whether the event is ischemic or hemorrhagic. Further diagnostics include a carotid Doppler, electrocardiogram, and transcranial Doppler.
What is one of the earliest signs of increased ICP?
Correct response: decreased level of consciousness (LOC) Explanation: 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 is receiving intravenous (IV) mannitol to prevent increased intracranial pressure. The order is for mannitol 1.5 grams per kg of body weight IV now. The client weighs 143 lbs (65 kg). How many grams will the nurse administer to the client? Enter the correct number in tenths.
Correct response: 97.5 Explanation: 143 lbs/2.2 = 65 kg. 65 kg x 1.5 = 97.5 grams.
The nurse is completing an assessment on a client with myasthenia gravis. Which of the following historical recounting provides the most significant evidence regarding when the disorder began?
Correct response: Drooping eyelids Explanation: Ptosis (eyelid drooping) is the most common manifestation of myasthenia gravis. Muscle weakness varies depending on the muscles affected. Shortness of breath and respiratory distress occurs later as the disease progresses. Muscle spasms are more likely in multiple sclerosis. Photophobia is not significant in myasthenia gravis.
Which terms refers to blindness in the right or left half of the visual field in both eyes?
Correct response: Homonymous hemianopsia Explanation: Homonymous hemianopsia occurs with occipital lobe tumors. Scotoma refers to a defect in vision in a specific area in one or both eyes. Diplopia refers to double vision or the awareness of two images of the same object occurring in one or both eyes. Nystagmus refers to rhythmic, involuntary movements or oscillations of the eyes.
The nurse is caring for a client with dysphagia. Which intervention would be contraindicated while caring for this client?
Correct response: Placing food on the affected side of the mouth Explanation: Interventions for dysphagia include placing food on the unaffected side of the mouth, allowing ample time to eat, assisting the client with meals, and testing the client's gag reflex before offering food or fluids.
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?
Correct response: 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.
Neurological level of spinal cord injury refers to which of the following?
Correct response: The lowest level at which sensory and motor function is normal Explanation: "Neurologic level" refers to the lowest level at which sensory and motor functions are normal. It is not the level of spinal cord transection, the best possible level of recovery, or the highest level at which sensory and motor function is normal.
When the nurse observes that the client has extension and external rotation of the arms and wrists and plantar flexion of the feet, the nurse records the client's posture as
Correct response: decerebrate. Explanation: Decerebrate posturing is the result of lesions at the midbrain and is more ominous than decorticate posturing. The client's head and neck arch backward, and the muscles are rigid. In decorticate posturing, which results from damage to the nerve pathway between the brain and spinal cord and is also very serious, the client has flexion and internal rotation of the arms and wrists, as well as extension, internal rotation, and plantar flexion of the feet.
A client diagnosed with a stroke is having difficulty forming words during communication. This would be appropriately documented as
Correct response: dysarthria. Explanation: Dysarthria is difficulty in forming words. Dysphagia is difficulty swallowing. Receptive aphasia is the inability to comprehend the spoken word. Diplopia is double vision.
A client is being treated for increased intracranial pressure (ICP). The nurse should ensure that the client does not develop hypothermia because:
Correct response: shivering in hypothermia can increase ICP. Explanation: Care must be taken to avoid the development of hypothermia because hypothermia causes shivering. Shivering, in turn, can increase intracranial pressure.
A client has been diagnosed as having global aphasia. The nurse recognizes that the client will be unable to perform which action?
Correct response: Form words that are understandable or comprehend spoken words Explanation: Global aphasia is a combination of expressive and receptive aphasia and presents a tremendous challenge to the nurse to effectively communicate with the client. In receptive and expressive aphasia, the client is unable to form words that are understandable. The client who is unable to speak at all is referred to as mute. Chapter 67: Management of Patients With Cerebrovascular Disorders, Table 67-2, p. 2012.
A nurse is instructing the spouse of a client who suffered a stroke about the use of eating devices the client will be using. During the teaching, the spouse starts to cry and states, "One minute he is laughing, and the next he's crying; I just don't understand what's wrong with him." Which statement is the best response by the nurse?
Correct response: "Emotional lability is common after a stroke, and it usually improves with time." Explanation: This is the most therapeutic and informative response. Often, most relatives of clients with stroke handle the physical changes better than the emotional aspects of care. The family should be prepared to expect occasional episodes of emotional lability. The client may laugh or cry easily and may be irritable and demanding or depressed and confused. The nurse can explain to the family that the client's laughter does not necessarily connote happiness, nor does crying reflect sadness, and that emotional lability usually improves with time. The remaining responses are nontherapeutic and do not address the spouse's concerns.
A patient sustained a head trauma in a diving accident and has a cerebral hemorrhage located within the brain. What type of hematoma is this classified as?
Correct response: An intracerebral hematoma Explanation: Intracerebral hemorrhage (hematoma) is bleeding within the brain, into the parenchyma of the brain. It is commonly seen in head injuries when force is exerted to the head over a small area (e.g., missile injuries, bullet wounds, stab injuries). A subdural hematoma (SDH) is a collection of blood between the dura and the brain, a space normally occupied by a thin cushion of cerebrospinal fluid. After a head injury, blood may collect in the epidural (extradural) space between the skull and the dura.
The nurse 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
Correct response: Apply warm or cool cloths to the forehead or back of the neck Explanation: 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. A client with transient ischemic attacks is advised to maintain hydration and drink eight glasses of fluid a day. A Heimlich maneuver is performed to clear the airway if the client cannot speak or breathe after swallowing food. The nurse uses pressure-relieving pads or a similar type of mattress to maintain peripheral circulation in the client's body.

At which of the following spinal cord injury levels does the patient have full head and neck control?
Correct response: 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 of the following is the earliest and most significant sign of increasing intracranial pressure (ICP)?
Correct response: Change in level of consciousness (LOC) Explanation: The earliest sign of increasing ICP is a change in LOC. Any changes in LOC should be reported immediately. Seizures, restlessness, and pupil changes may occur, but these are not the earliest signs.
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?
Correct response: Compliance with the prescribed medication regimen Explanation: 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.
The nurse is evaluating the transmission of a report from a paramedic unit to the emergency room. The medic reports that a client is unconscious with edema of the head and face and Battle's sign. What clinical picture would the nurse anticipate?
Correct response: Edema to the head with bruising of the mastoid process Explanation: Battle's sign is the presence of bruising of the mastoid process behind the ear. It is not related to periorbital bleeding, lacerations, or fixed pupils.
A client undergoes cerebral angiography for evaluation of a subarachnoid hemorrhage. Which findings indicate spasm or occlusion of a cerebral vessel by a clot?
Correct response: Hemiplegia, seizures, and decreased level of consciousness Explanation: Spasm or occlusion of a cerebral vessel by a clot causes signs and symptoms similar to those of a stroke: hemiplegia, seizures, decreased level of consciousness, aphasia, hemiparesis, and increased focal symptoms. Nausea, vomiting, and profuse sweating suggest a delayed reaction to the contrast medium used in cerebral angiography. Difficulty breathing or swallowing may signal a hematoma in the neck. Tachycardia, tachypnea, and hypotension suggest internal hemorrhage.
The nurse is educating a patient with a seizure disorder. What nutritional approach for seizure management would be beneficial for this patient?
Correct response: High in protein and low in carbohydrate Explanation: 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
A client has experienced an ischemic stroke that has damaged the lower motor neurons of the brain. Which of the following deficits would the nurse expect during assessment?
Correct response: Lack of deep tendon reflexes Explanation: Damage to the occipital lobe can result in visual agnosia, whereas damage to the temporal lobe can cause auditory agnosia. If damage has occurred to the frontal lobe, learning capacity, memory, or other higher cortical intellectual functions may be impaired. Such dysfunction may be reflected in a limited attention span, difficulties in comprehension, forgetfulness, and lack of motivation. Damage to the lower motor neurons may cause decreased muscle tone, flaccid muscle paralysis, and a decrease in or loss of reflexes.
What clinical manifestations does the nurse recognize when a patient has had a right hemispheric stroke?
Correct response: Left visual field deficit Explanation: A left visual field deficit is a common clinical manifestation of a right hemispheric stroke. Aphasia, slow, cautious behavior, and altered intellectual ability are all clinical manifestations of a left hemispheric stroke.
A client is admitted with weakness, expressive aphasia, and right hemianopia. The brain MRI reveals an infarct. The nurse understands these symptoms to be suggestive of which of the following findings?
Correct response: Left-sided cerebrovascular accident (CVA) Explanation: When the infarct is on the left side of the brain, the symptoms are likely to be on the right, and the speech is more likely to be involved. If the MRI reveals an infarct, TIA is no longer the diagnosis. There is not enough information to determine if the stroke is still evolving or is complete.
What does the nurse recognize as the earliest sign of serious impairment of brain circulation related to increasing ICP?
Correct response: Lethargy and stupor Explanation: 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 client with a traumatic brain injury is showing early signs of increasing intracranial pressure (ICP). While planning care for this client, what would be the priority expected outcome?
Correct response: Maintains a patent airway Explanation: Maintenance of a patent airway is always a first priority. Loss of airway is a possible complication of increasing ICP, as well as aspiration from vomiting.
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 actions would be the first priority?
Correct response: Maintenance of a patent airway Explanation: The most important consideration in managing the patient with altered LOC is to establish an adequate airway and ensure ventilation.
A client who complains of recurring headaches, accompanied by increased irritability, photophobia, and fatigue is asked to track the headache symptoms and occurrence on a calendar log. Which is the best nursing rationale for this action?
Correct response: Migraines often coincide with menstrual cycle. Explanation: Changes in reproductive hormones as found during menstrual cycle can be a trigger for migraine headaches and may assist in the management of the symptoms. Cluster headaches can cause severe pain but is not the reason for tracking. Tension headaches can be managed but is not associated with a monthly calendar. Headaches are common but not the reason for tracking.
A client with neurologic infection develops cerebral edema from syndrome of inappropriate antidiuretic hormone (SIADH). Which is an important nursing action for this client?
Correct response: Restricting fluid intake and hydration Explanation: 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.
A client with neurological infection develops cerebral edema from syndrome of inappropriate antidiuretic hormone (SIADH). Which is an important nursing action for this client?
Correct response: Restricting fluid intake and hydration Explanation: 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 neurological infection should be given tracheal suctioning and hyperoxygenation only when respiratory distress develops.
Following a generalized seizure in a client, which nursing assessment is a priority for detailing the event?
Correct response: Seizure was 1 minute in duration including tonic-clonic activity. Explanation: Describing the length and the progression of the seizure is a priority nursing responsibility. During this time, the client will experience respiratory spasms, and their skin will appear cyanotic, indicating a period of lack of tissue oxygenation. Noting when the seizure began and presence of an aura are also valuable pieces of information. Postictal behavior should be documented along with vital signs, oxygen saturation, and assessment of tongue and oral cavity.
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:
Correct response: 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 participating in a health fair for stroke prevention. Which will the nurse say is a modifiable risk factor for ischemic stroke?
Correct response: Smoking Explanation: Modifiable risk factors for transient ischemic attack (TIA) and ischemic stroke include hypertension, type 1 diabetes, cardiac disease, smoking, and chronic alcoholism. Advanced age, gender, and race are nonmodifiable risk factors for stroke
A client's spouse relates how the client reported a severe headache and then was unable to talk or move their right arm and leg. After diagnostics are completed and the client is admitted to the hospital, when would basic rehabilitation begin?
Correct response: immediately Explanation: Beginning basic rehabilitation during the acute phase is an important nursing function. Measures such as position changes and prevention of skin breakdown and contractures are essential aspects of care during the early phase of rehabilitation. The nursing goal is to prevent complications that may interfere with the client's potential to recover function
A 64-year-old client reports symptoms consistent with a transient ischemic attack (TIA) to the health care provider in the emergency department. Which is the origin of the client's symptoms?
Correct response: impaired cerebral circulation Explanation: TIAs involve the same mechanism as in the ischemic cascade, but symptoms are transient (< 24 hours) and there is no evidence of cerebral tissue infarction. The ischemic cascade begins when cerebral blood flow decreases to less than 25 mL/100 g/min and neurons are no longer able to maintain aerobic respiration. Thus, a TIA results directly from impaired blood circulation in the brain. Atherosclerosis, cardiac disease, hypertension, or diabetes can be risk factors for a TIA but do not cause it.
A client is treated for increased intracranial pressure (ICP). It is important for the client to avoid hypothermia because
Correct response: shivering in hypothermia can increase ICP. Explanation: The nurse should avoid hypothermia in a client with increased ICP because hypothermia causes shivering. Shivering, in turn, can increase intracranial pressure. Hypothermia in a client with ICP does not indicate malaria or meningitis and is not likely to cause death.
A nurse is caring for a client with L1-L2 paraplegia who is undergoing rehabilitation. Which goal is appropriate?
Correct response: Establishing an intermittent catheterization routine every 4 hours Explanation: The paraplegic client with an L1-L2 injury will demonstrate flaccid paralysis. Developing an intermittent catheterization routine offers a way of manually draining the bladder, eliminating the need for an indwelling urinary catheter. With an injury at L1-L2, ambulation may be possible with long leg braces but not with short leg braces. Spasticity and autonomic dysreflexia are seen in clients with upper motor injuries above T6, not L1-L2 injuries.
The nurse is caring for a client with an inoperable brain tumor. What teaching is important for the nurse to do with these clients?
Correct response: Explaining hospice care and services Explanation: 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.
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.
Correct response: 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 has been diagnosed as having global aphasia. The nurse recognizes that the client will be unable to perform which action?
Correct response: Form words that are understandable or comprehend spoken words Explanation: Global aphasia is a combination of expressive and receptive aphasia and presents a tremendous challenge to the nurse to effectively communicate with the client. In receptive and expressive aphasia, the client is unable to form words that are understandable. The client who is unable to speak at all is referred to as mute.
From which direction should a nurse approach a client who is blind in the right eye?
Correct response: From the left side of the client Explanation: The nurse should approach the client from the left side so that the client can be aware of the nurse's approach. Likewise, personal items should be placed on the client's left side so that he can see them easily.
A client diagnosed with migraine headaches asks the nurse what he can do to help control the headaches and minimize the number of attacks he is having. What instructions should the nurse give this client?
Correct response: Identify and avoid factors that precipitate or intensify an attack. Explanation: The nurse includes the following instructions: Follow the indications and dosage regimen for medication and notify the physician of any adverse drug effects. Identify and avoid factors that precipitate or intensify an attack. Keeping a food diary may help identify foods that trigger attacks. Keep a record of the attacks, including activities before the attack and environmental or emotional circumstances that appear to bring on the attack. Lie down in a darkened room and avoid noise and movement when an attack occurs, if that is possible.
A patient comes to the emergency department with a large scalp laceration after being struck in the head with a glass bottle. After assessment of the patient, what does the nurse do before the physician sutures the wound?
Correct response: Irrigates the wound to remove debris Explanation: Scalp wounds are potential portals of entry for organisms that cause intracranial infections. Therefore, the area is irrigated before the laceration is sutured to remove foreign material and to reduce the risk for infection.
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?
Correct response: 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 term refers to muscular hypertonicity in a weak muscle, with increased resistance to stretch?
Correct response: 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 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?
Correct response: 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.
Which is a contraindication for the administration of tissue plasminogen activator (t-PA)?
Correct response: Intracranial hemorrhage Explanation: Intracranial hemorrhage, neoplasm, and aneurysm are contraindications for t-PA. Clinical diagnosis of ischemic stroke, age 18 years or older, and a systolic blood pressure less than or equal to 185 mm Hg are eligibility criteria.
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?
Correct response: "There is a strong familial tendency." Explanation: Migraine headaches have a strong familial tendency. Migraines are primary headaches, not secondary headaches.
When planning care for a client with a head injury, which position should the nurse include in the care plan to enhance client outcomes?
Correct response: 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
A patient is admitted via ambulance to the emergency room of a stroke center at 1:30 p.m. with symptoms that the patient said began at 1:00 p.m. Within 1 hour, an ischemic stroke had been confirmed and the doctor ordered tPA. The nurse knows to give this drug no later than what time?
Correct response: 4:00 p.m. Explanation: Tissue plasminogen activator (tPA) must be given within 3 hours after symptom onset. Therefore, since symptom onset was 1:00 pm, the window of opportunity ends at 4:00 pm.
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?
Correct response: Administer stool softeners. Explanation: 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.
A nurse is teaching a community group about modifiable and nonmodifiable risk factors for ischemic strokes. Which of the following is a risk factor that cannot be modified?
Correct response: Advanced age Explanation: Modifiable risk factors for ischemic stroke include hypertension, atrial fibrillation, hyperlipidemia, diabetes mellitus, smoking, asymptomatic carotid stenosis, obesity, and excessive alcohol consumption. Nonmodifiable risk factors include advanced age, gender, and race.
Which is a late sign of increased intracranial pressure (ICP)?
Correct response: Altered respiratory patterns Explanation: Altered respiratory patterns are late signs of increased ICP and may indicate pressure or damage to the brainstem. Headache, irritability, and any change in LOC are early signs of increased ICP. Speech changes, such as slowed speech or slurring, are also early signs of increased ICP
The nurse is taking care of a client with a headache. In addition to administering medications, the nurse takes which measure to assist the client in reducing the pain associated with the headache?
Correct response: Apply warm or cool cloths to the forehead or back of the neck. Explanation: Warmth promotes vasodilation; cool stimuli reduce blood flow.
A client is diagnosed with a brain tumor. As the nurse assists the client from the bed to a chair, the client begins having a generalized seizure. Which action should the nurse take first?
Correct response: Assist the client to the floor, in a side-lying position, and protect him with linens. Explanation: The nurse should protect the client from injury by assisting him to the floor, in a side-lying position, and protect him from harm by padding the floor with bed linens. Initiating a response from the code team isn't necessary because seizures are self-limiting. As long as the client's airway is protected, his cardiopulmonary status isn't affected. The nurse shouldn't force anything into the client's mouth during a seizure; doing so may cause injury. Documenting seizure activity is important, but it doesn't take priority over client safety.
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?
Correct response: Basilar Explanation: Basilar skull fractures are suspected when cerebrospinal fluid (CSF) escapes from the ears (CSF otorrhea) and/or the nose (CSF rhinorrhea).
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?
Correct response: 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.
Which posture exhibited by abnormal flexion of the upper extremities and extension of the lower extremities?
Correct response: Decorticate Explanation: Decorticate posturing is an abnormal posture associated with severe brain injury, characterized by abnormal flexion of the upper extremities and extension of the lower extremities. Decerebration is an abnormal body posture associated with a severe brain injury, characterized by extreme extension of the upper and lower extremities. Flaccidity occurs when the client has no motor function, is limp, and lacks motor tone.
Which is the most common motor dysfunction seen in clients diagnosed with stroke?
Correct response: Hemiplegia Explanation: The most common motor dysfunction is hemiplegia (paralysis of one side of the body) caused by a lesion on the opposite side of the brain. Ataxia is impaired ability to coordinate movement. Diplopia is double vision. Hemiparesis is weakness of one side of the body.
The nurse is caring for a client diagnosed with a hemorrhagic stroke. The nurse recognizes that which intervention is most important?
Correct response: Maintaining a patent airway Explanation: Maintaining the airway is the most important nursing intervention. Immediate complications of a hemorrhagic stroke include cerebral hypoxia, decreased cerebral blood flow, and extension of the area of injury. Providing adequate oxygenation of blood to the brain minimizes cerebral hypoxia. Brain function depends on delivery of oxygen to the tissues. Administering supplemental oxygen and maintaining hemoglobin and hematocrit at acceptable levels will assist in maintaining tissue oxygenation. All other interventions are appropriate, but the airway takes priority. The head of the bed should be elevated to 30 degrees, monitoring the client because of the risk for seizures, and stool softeners are recommended to prevent constipation and straining, but these are not the most important interventions.
After having a stroke, a patient has cognitive deficits. What are the cognitive deficits the nurse recognizes the patient has as a result of the stroke? Select all that apply.
Correct response: Poor abstract reasoning Decreased attention span Short- and long-term memory loss Explanation: Cognitive deficits associated with stroke include short- and long-term memory loss, decreased attention span, and poor abstract reasoning. Expressive aphasia is a verbal deficit, not a cognitive deficit. Paresthesias are sensory deficits, not cognitive deficits.
The nurse is caring for a client diagnosed with a subarachnoid hemorrhage resulting from a leaking aneurysm. The client is awaiting surgery. Which nursing interventions would be appropriate for the nurse to implement? Select all that apply.
Correct response: Provide a dimly lit environment. Elevate the head of bed 30 degrees. Administer docusate per order. Explanation: Cerebral aneurysm precautions are implemented for the patient with a diagnosis of aneurysm to provide a nonstimulating environment, prevent increases in intracranial pressure (ICP), and prevent further bleeding. The patient is placed on immediate and absolute bed rest in a quiet, nonstressful environment, because activity, pain, and anxiety elevate blood pressure, which increases the risk for bleeding. Visitors, except for family, are restricted. Dim lighting is helpful because photophobia (visual intolerance of light) is common. The head of the bed is elevated 15 to 30 degrees to promote venous drainage and decrease ICP. No enemas are permitted, but stool softeners (Colace) and mild laxatives are prescribed. Both prevent constipation, which would cause an increase in ICP, as would enemas.
Which of the following types of hematoma results from venous bleeding with blood gradually accumulating in the space below the dura?
Correct response: 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.
A patient has an S5 spinal fracture from a fall. What type of assistive device will this patient require?
Correct response: The patient will be able to ambulate independently. Explanation: Patients with spinal cord injuries from S1 to S5 should be able to ambulate independently, without an assistive device.
A client is hospitalized when presenting to the emergency department with right-sided weakness. Within 6 hours of being admitted, the neurologic deficits had resolved and the client was back to his presymptomatic state. The nurse caring for the client knows that the probable cause of the neurologic deficit was what?
Correct response: Transient ischemic attack Explanation: A transient ischemic attack (TIA) is a sudden, brief attack of neurologic impairment caused by a temporary interruption in cerebral blood flow. Symptoms may disappear within 1 hour; some continue for as long as 1 day. When the symptoms terminate, the client resumes his or her presymptomatic state. The symptoms do not describe a left- or right-sided stroke or a cerebral aneurysm.
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?
Correct response: poor Explanation: 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.
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?
Correct response: 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 fluid (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.
You are a neurotrauma nurse working in a neuro ICU. What would you know is an acute emergency and is seen in clients with a cervical or high thoracic spinal cord injury after the spinal shock subsides?
Correct response: Autonomic dysreflexia Autonomic dysreflexia is an acute emergency and is seen in clients with a cervical or high thoracic spinal cord injury, usually after the spinal shock subsides. Tetraplegia results in the paralysis of all extremities when there is a high cervical spine injury. Paraplegia occurs with injuries at the thoracic level. Areflexia is a loss of sympathetic reflex activity below the level of injury within 30 to 60 minutes of a spinal injury.
When caring for a client who is post-intracranial surgery, what is the most important parameter to monitor?
Correct response: Body temperature Explanation: It is important to monitor the client's body temperature closely; hyperthermia increases brain metabolism, increasing the potential for brain damage. Therefore, elevated temperature must be relieved with an antipyretic and other measures. Options A, B, and C are not the most important parameters to monitor.
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.
Correct response: Bradycardia Bradypnea Hypertension Explanation: 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.
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.
Correct response: Bradycardia Hypertension Bradypnea Explanation: 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.
An older client complains of a constant headache. A physical examination shows papilledema. What may the symptoms indicate in this client?
Correct response: Brain tumor Explanation: The incidence of brain tumor increases 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 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?
Correct response: Decerebrate Explanation: 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.
A client with a traumatic brain injury has already displayed early signs of increasing intracranial pressure (ICP). Which of the following would be considered late signs of increasing ICP?
Correct response: Decerebrate posturing and loss of corneal reflex Explanation: Early indications of increasing ICP include disorientation, restlessness, increased respiratory effort, mental confusion, pupillary changes, weakness on onside of the body or in one extremity, and constant, worsening headache. Later indications of increasing ICP include decreasing level of consciousness until client is comatose, decreased or erratic pulse and respiratory rate, increased blood pressure and temperature, widened pulse pressure, Cheyne-Stokes breathing, projectile vomiting, hemiplegia or decorticate or decerebrate posturing, and loss of brain stem reflexes (pupillary, corneal, gag, and swallowing).
A client undergoes a craniotomy with supratentorial surgery to remove a brain tumor. On the first postoperative day, the nurse notes the absence of a bone flap at the operative site. How should the nurse position the client's head?
Correct response: Elevated 30 degrees. Explanation: After supratentorial surgery, the nurse should elevate the client's head 30 degrees to promote venous outflow through the jugular veins. The nurse would keep the client's head flat after infratentorial, not supratentorial, surgery. However, after supratentorial surgery to remove a chronic subdural hematoma, the neurosurgeon may order the nurse to keep the client's head flat; typically, the client with such a hematoma is older and has a less expandable brain. A client without a bone flap can't be positioned with the head turned onto the operative side because doing so may injure brain tissue. Elevating the head 10 degrees or less wouldn't promote venous outflow through the jugular veins.
The nurse is caring for a client with aphasia. Which strategy will the nurse use to facilitate communication with the client?
Correct response: Establishing eye contact Explanation: The following strategies should be used by the nurse to encourage communication with a client with aphasia: face the client and establish eye contact, speak in your usual manner and tone, use short phrases, and pause between phrases to allow the client time to understand what is being said; limit conversation to practical and concrete matters; use gestures, pictures, objects, and writing; and as the client uses and handles an object, say what the object is. It helps to match the words with the object or action. Be consistent in using the same words and gestures each time you give instructions or ask a question, and keep extraneous noises and sounds to a minimum. Too much background noise can distract the client or make it difficult to sort out the message being spoken.
The nurse is caring for a client with a head injury. The client is experiencing CSF rhinorrhea. Which order should the nurse question?
Correct response: 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.
An emergency department nurse is interviewing a client who is presenting with signs of an ischemic stroke that began 2 hours ago. The client reports a history of a cholecystectomy 6 weeks ago and is taking digoxin, warfarin, and labetalol. What factor poses a threat to the client for thrombolytic therapy?
Correct response: International normalized ratio greater than 2 Explanation: The client is at risk for further bleeding if the international normalized ratio is greater than 2. Thrombolytic therapy must be initiated within 3 hours in clients with ischemic stroke. The client is not eligible for thrombolytic therapy if she has had surgery within 14 days. Digoxin and labetalol do not prohibit thrombolytic therapy.
A client in the intensive care unit (ICU) has a traumatic brain injury. The nurse must implement interventions to help control intracranial pressure (ICP). Which of the following are appropriate interventions to help control ICP?
Correct response: Keep the client's neck in a neutral position (no flexing). Explanation: To assist in controlling ICP in clients with severe brain injury, the following are recommended: elevate the head of the bed as prescribed (gravity helps drain fluid), maintain head/neck in neutral alignment (no twisting or flexing), give sedation as ordered to prevent agitation, and avoid noxious stimuli (scatter procedures so that client does not become overtired).
A patient who has suffered a stroke begins having complications regarding spasticity in the lower extremity. What ordered medication does the nurse administer to help alleviate this problem?
Correct response: Lioresal (Baclofen) Explanation: Spasticity, particularly in the hand, can be a disabling complication after stroke. Botulinum toxin type A injected intramuscularly into wrist and finger muscles has been shown to be effective in reducing this spasticity (although the effect is temporary, typically lasting 2 to 4 months) (Teasell, Foley, Pereira, et al., 2012). Other treatments for spasticity may include stretching, splinting, and oral medications such as baclofen (Lioresal).
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?
Correct response: 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 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
Correct response: 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?
Correct response: 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. Chapter 68: Management of Patients With Neurologic Trauma, Nursing Management of a Patient in a Cast, Splint, or Brace, p. 1134.
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?
Correct response: 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.
Which method is used to help reduce intracranial pressure?
Correct response: Using a cervical collar Explanation: 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
The nurse is providing information about strokes to a community group. Which of the following would the nurse identify as the primary initial symptoms of an ischemic stroke?
Correct response: Weakness on one side of the body and difficulty with speech Explanation: The main presenting symptoms for an ischemic stroke are numbness or weakness of the face, arm, or leg, especially on one side of the body; confusion or change in mental status; and trouble speaking or understanding speech. Severe headache, vomiting, early change in level of consciousness, and seizures are early signs of a hemorrhagic stroke. Foot drop and external hip rotation are things that can occur if a stroke victim is not turned or positioned correctly.
A client reports light-headedness, speech disturbance, and left-sided weakness that have lasted for several hours. In the examination, an abnormal sound is auscultated in an artery leading to the brain. What is the term for the auscultated discovery?
Correct response: bruit Explanation: A neurologic examination during an attack reveals neurologic deficits. Auscultation of the artery may reveal a bruit (abnormal sound caused by blood flowing over a rough surface within one or both carotid arteries). The term for the auscultated discovery is "bruit."
When communicating with a client who has sensory (receptive) aphasia, the nurse should:.
Correct response: use short, simple sentences. Explanation: Although sensory aphasia allows the client to hear words, it impairs the ability to comprehend their meaning. The nurse should use short, simple sentences to promote comprehension. Allowing time for the client to respond might be helpful but is less important than simplifying the communication. Because the client's hearing isn't affected, speaking loudly isn't necessary. A writing pad is helpful for clients with expressive, not receptive, aphasia.
A client with a traumatic brain injury has developed increased intracranial pressure resulting in diabetes insipidus. The expected treatment would consist of which of the following?
Correct response: Vasopressin therapy Explanation: Diabetes insipidus is the result of decreased secretion of antidiuretic hormone (ADH). The client has excessive urine output, decreased urine osmolality, and serum hyperosmolarity. Treatment consists of administration of fluids, electrolyte replacement, and vasopressin therapy. SIADH is the result of increased secretion of antidiuretic hormone (ADH). The client becomes volume overloaded, urine output diminishes, and serum sodium concentration becomes dilute. Treatment consists of fluid restriction (less than 800 mL/day with no free water). In severe cases, careful administration of a 3% hypertonic saline solution may be therapeutic.
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?
Correct response: 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.
