NEURO RNSG 2514

The nurse is performing an assessment on a client with a diagnosis of Bell's palsy. The nurse should expect to observe which finding in the client? 1. Facial drooping 2. Periorbital edema 3. Ptosis of the eyelid 4. Twitching on the affected side of the face

1 Bell's palsy is a one-sided facial paralysis caused by the compression of the facial nerve (cranial nerve VII). Assessment findings include facial droop from paralysis of the facial muscles; increased lacrimation; painful sensations in the eye, face, or behind the ear; and speech or chewing difficulty. The remaining options are not associated findings in Bell's palsy.

The nurse is caring for a client with a head injury. The client's intracranial pressure reading is 8 mm Hg. Which condition should the nurse document? 1. The intracranial pressure reading is normal. 2. The intracranial pressure reading is elevated. 3. The intracranial pressure reading is borderline. 4. An intracranial pressure reading of 8 mm Hg is low.

1 The normal intracranial pressure is 5 to 15 mm Hg. A pressure of 8 mm Hg is within normal range.

The home care nurse is performing an assessment on a client with a diagnosis of Bell's palsy. Which assessment question will elicit specific information regarding this client's disorder? 1. "Do your eyes feel dry?" 2. "Do you have any spasms in your throat?" 3. "Are you having any difficulty chewing food?" 4. "Do you have any tingling sensations around your mouth?"

3 Bell's palsy is a one-sided facial paralysis caused by compression of the facial nerve. Manifestations include facial droop from paralysis of the facial muscles; increased lacrimation; painful sensations in the eye, face, or behind the ear; and speech or chewing difficulties.

The nurse is assessing the nasal dressing on a client who had a transsphenoidal resection of the pituitary gland. The nurse notes a small amount of serosanguineous drainage that is surrounded by clear fluid on the nasal dressing. Which nursing action is most appropriate? 1. Document the findings. 2. Reinforce the dressing. 3. Notify the health care provider (HCP). 4. Mark the area of drainage with a pen and monitor for further drainage.

3 Cerebrospinal fluid (CSF) leakage after cranial surgery may be detected by noting drainage that is serosanguineous surrounded by an area of straw-colored or pale drainage. The physical appearance of CSF drainage is that of a halo. If the nurse notes the presence of this type of drainage, the HCP needs to be notified. The remaining options are inappropriate nursing actions.

The nurse caring for a client following craniotomy who has a supratentorial incision understands that the client should most likely be maintained in which position? 1. Prone position 2. Supine position 3. Semi Fowler's position 4. Dorsal recumbent position

3 In supratentorial surgery (surgery above the brain's tentorium), the client's head is usually elevated 30 degrees to promote venous outflow through the jugular veins. The client's head or the head of the bed is not lowered in the acute phase of care after supratentorial surgery. An exception to this is the client who has undergone evacuation of a chronic subdural hematoma, but a health care provider's (HCP's) prescription is required for positions other than those involving head elevation. In addition, the HCP's prescription regarding positioning is always checked and agency procedures are always followed.

The nurse is caring for a client with an intracranial pressure (ICP) monitoring device. The nurse should become most concerned if the ICP readings drifted to and stayed in the vicinity of which finding? 1. 5 mm Hg 2. 8 mm Hg 3. 14 mm Hg 4. 22 mm Hg

4 Normal ICP readings range from 5 to 15 mm Hg pressure. Pressures greater than 20 mm Hg are considered to represent increased ICP, which seriously impairs cerebral perfusion.

The nurse in the neurological unit is monitoring a client for signs of increased intracranial pressure (ICP). The nurse reviews the assessment findings for the client and notes documentation of the presence of Cushing's reflex. The nurse determines that the presence of this reflex is obtained by assessing which item? 1. Blood pressure 2. Motor response 3. Pupillary response 4. Level of consciousness

1 Cushing's reflex is a late sign of increased ICP and consists of a widening pulse pressure (systolic pressure rises faster than diastolic pressure) and bradycardia. The remaining options are unrelated to monitoring for Cushing's reflex.

A client who had a stroke (brain attack) has right-sided hemianopsia. What should the nurse plan to do to help the client adapt to this problem? 1. Teach the client to scan the environment. 2. Place all objects within the left visual field. 3. Place all objects within the right visual field. 4. Ensure that the family brings the client's eyeglasses to hospital.

1 Hemianopsia is blindness in half of the visual field. The client with hemianopsia is taught to scan the environment. This allows the client to take in the entirety of the visual field, which is necessary for proper functioning within the environment and helps to prevent injury to the client. Options 2 and 3 will not help the client adapt to this visual impairment. Eyeglasses are useful if the client already wears them, but they will not correct this visual field deficit.

A client arrives in the hospital emergency department with a closed head injury to the right side of the head caused by an assault with a baseball bat. The nurse assesses the client neurologically, looking primarily for motor response deficits that involve which area? 1. The left side of the body 2. The right side of the body 3. Both sides of the body equally 4. Cranial nerves only, such as speech and pupillary response

1 Motor responses such as weakness and decreased movement will be seen on the side of the body that is opposite an area of head injury. Contralateral deficits result from compression of the cortex of the brain or the pyramidal tracts. Depending on the severity of the injury, the client may have a variety of neurological deficits.

A client who had cranial surgery 5 days earlier to remove a brain tumor has a few cognitive deficits and does not seem to be progressing as quickly as the client or family had hoped. The nurse plans to implement which approach as most helpful to the client and family at this time? 1. Emphasize progress in a realistic manner. 2. Set high goals to give the client something to "aim for." 3. Tell the family to be extremely optimistic with the client. 4. Inform the client and family of standardized goals of care.

1 The most helpful approach by the nurse is to emphasize progress that is being made in a realistic manner. The nurse does not offer false hope but does provide factual information in a clear and positive manner. The nurse encourages the family to be realistic in their expectations and attitudes. The plan of care should be individualized for each clien

A client who is experiencing an inferior wall myocardial infarction has had a drop in heart rate into the range of 50 to 56 beats/minute. The client also is complaining of nausea. On the basis of these findings, the nurse determines that the client is experiencing parasympathetic stimulation of which cranial nerve? 1. Vagus (CN X) 2. Hypoglossal (CN XII) 3. Spinal accessory (CN XI) 4. Glossopharyngeal (CN IX)

1 The vagus nerve is responsible for sensations in the thoracic and abdominal viscera. It also is responsible for the decrease in heart rate because approximately 75% of all parasympathetic stimulation is carried by the vagus nerve. CN XII is responsible for tongue movement. CN XI is responsible for neck and shoulder movement. CN IX is responsible for taste in the posterior two thirds of the tongue, pharyngeal sensation, and swallowing.

A client who is experiencing an inferior wall myocardial infarction has had a drop in heart rate into the 50 to 56 beats/minute range. The client is also complaining of nausea. Which cranial nerve damage should the nurse expect that the client is experiencing? 1. Vagus (CN X) 2. Hypoglossal (CN XII) 3. Spinal accessory (CN XI) 4. Glossopharyngeal (CN IX)

1 The vagus nerve is responsible for sensations in the thoracic and abdominal viscera. It is also responsible for the decrease in heart rate because approximately 75% of all parasympathetic stimulation is carried by the vagus nerve. CN IX is responsible for taste in the posterior two thirds of the tongue, pharyngeal sensation, and swallowing. CN XI is responsible for neck and shoulder movement. CN XII is responsible for tongue movement.

The nurse is planning to perform an assessment of the client's level of consciousness using the Glasgow Coma Scale. Which assessments should the nurse include in order to calculate the score? Select all that apply. 1. Eye opening 2. Reflex response 3. Best verbal response 4. Best motor response 5. Pupil size and reaction

1,3,4 Assessment of pupil size and reaction and reflex response are not part of the Glasgow Coma Scale. The 3 categories included are eye opening, best verbal response, and best motor response. Pupil assessment and reflex response is a necessary part of a total assessment of the neurological status of a client but is not part of this particular scale.

A client has suffered damage to Broca's area of the brain. Which priority assessment should the nurse perform? 1. Speech 2. Hearing 3. Balance 4. Level of consciousness

1 Broca's area in the brain is responsible for the motor aspects of speech, through coordination of the muscular activity of the tongue, mouth, and larynx. The term assigned to damage in this area is aphasia. The items listed in the other options are not the responsibility of Broca's area.

A client with recent-onset Bell's palsy is upset and crying about the change in facial appearance. The nurse plans to support the client emotionally by making which statement to the client? 1. "This is not a stroke, and many clients recover in 3 to 5 weeks." 2. "This is caused by a small tumor, which can be removed easily." 3. "This is similar to a stroke, but all symptoms will reverse without treatment." 4. "This is a temporary problem, with treatment similar to that for migraine headaches."

1 Clients with Bell's palsy should be reassured that they have not experienced stroke a (brain attack) and that symptoms often disappear spontaneously in 3 to 5 weeks. The client is given supportive treatment for symptoms. Bell's palsy usually is not caused by a tumor, and the treatment is not similar to that for migraine headaches

The nurse is performing a neurological assessment on a client and is assessing the function of cranial nerves III, IV, and VI. Assessment of which aspect of function will yield the best information about these cranial nerves? 1. Eye movements 2. Response to verbal stimuli 3. Affect, feelings, or emotions 4. Insight, judgment, and planning

1 Eye movements are under the control of cranial nerves III, IV, and VI. Level of consciousness (response to verbal stimuli) is controlled by the reticular activating system and both cerebral hemispheres. Feelings are part of the role of the limbic system and involve both hemispheres. Insight, judgment, and planning are part of the function of the frontal lobe in conjunction with association fibers that connect to other areas of the cerebrum.

The nurse is providing care to a client with increased intracranial pressure (ICP). Which approach is beneficial in controlling the client's ICP from an environmental viewpoint? 1. Reduce environmental noise. 2. Allow visitors as desired by the client and family. 3. Awaken the client every 2 to 3 hours to monitor mental status. 4. Cluster nursing activities to reduce the number of interruptions.

1 Nursing interventions to control ICP include maintaining a calm, quiet, and restful environment. Environmental noise should be kept at a minimum. Visiting should be monitored to avoid emotional stress and interruption of sleep. Interventions should be spaced out over the shift to minimize the risk of a sustained rise in ICP.

The nurse is caring for a client who is in the chronic phase of stroke (brain attack) and has a right-sided hemiparesis. The nurse identifies that the client is unable to feed self. Which is the appropriate nursing intervention? 1. Assist the client to eat with the left hand to build strength. 2. Provide a pureed diet that is easy for the client to swallow. 3. Inform the client that a feeding tube will be placed if progress is not made. 4. Provide a variety of foods on the meal tray to stimulate the client's appetite.

1 Right-sided hemiparesis is weakness of the right arm and leg. The nurse should teach the client to use both sides of the body to increase strength and build endurance. Providing a pureed diet is incorrect. The question does not mention swallowing difficulty, so there is no need to puree the food. Informing the client that a feeding tube may need to be placed is incorrect. That information would come from the health care provider. Providing a variety of foods is also incorrect because the problem is not the food selection but the client's ability to eat the food independently.

Members of the family of an unconscious client with increased intracranial pressure are talking at the client's bedside. They are discussing the client's condition and wondering whether the client will ever recover. The nurse intervenes on the basis of which interpretation? 1. It is possible the client can hear the family. 2. The family needs immediate crisis intervention. 3. The client might have wanted a visit from the hospital chaplain. 4. The family could benefit from a conference with the health care provider.

1 Some clients who have awakened from an unconscious state have remembered hearing specific voices and conversations. Family and staff should assume that the client's sense of hearing is intact and act accordingly. In addition, positive outcomes are associated with coma stimulation-that is, speaking to and touching the client. The remaining options are incorrect interpretations.

A client has a cerebellar lesion. The nurse would plan to obtain which item for use by this client? 1. Walker 2. Slider board 3. Raised toilet seat 4. Adaptive eating utensils

1 The cerebellum is responsible for balance and coordination. A walker provides stability for the client during ambulation. A raised toilet seat is useful if the client has sufficient mobility or ability to flex the hips. A slider board is used in transferring a client with weak or paralyzed legs from a bed to stretcher or wheelchair. Adaptive eating utensils are beneficial if the client has partial paralysis of the hand.

The nurse is reviewing a discharge teaching plan for a postcraniotomy client that was prepared by a nursing student. The nurse would intervene and provide teaching to the student if the student included which home care instruction? 1. Sounds will not be heard clearly unless they are loud. 2. Obtain assistance with ambulation if the client is lightheaded. 3. Tub bath or shower is permitted, but the scalp is kept dry until the sutures are removed. 4. Use a check-off system for administering anticonvulsant medications to avoid missing doses.

1 The postcraniotomy client typically is sensitive to loud noises and can find them excessively irritating. Control of environmental noise by others will be helpful for this client. Seizures are a potential complication that may occur for up to 1 year after surgery. For this reason, the client must diligently take anticonvulsant medications. The client and family are encouraged to keep track of the doses administered. The family should learn seizure precautions and should accompany the client during ambulation if dizziness or seizures tend to occur. The suture line is kept dry until sutures are removed to prevent infection.

The nurse is caring for a client who is on bed rest as part of aneurysm precautions. The nurse should avoid doing which action when giving respiratory care to this client? 1. Encouraging hourly coughing 2. Assisting with incentive spirometer 3. Encouraging hourly deep breathing 4. Repositioning gently side to side every 2 hours

1 With aneurysm precautions, any activity that could raise the client's intracranial pressure (ICP) is avoided. For this reason, activities such as straining, coughing, blowing the nose, and even sneezing are avoided whenever possible. The other interventions (repositioning, deep breathing, and incentive spirometry) do not provide added risk of increasing ICP and are beneficial in reducing the respiratory complications of bed rest.

The nurse has just admitted to the nursing unit a client with a basilar skull fracture who is at risk for increased intracranial pressure. Pending specific health care provider prescriptions, the nurse should safely place the client in which positions? Select all that apply. 1. Head midline 2. Neck in neutral position 3. Head of bed elevated 30 to 45 degrees 4. Head turned to the side when flat in bed 5. Neck and jaw flexed forward when opening the mouth

1,2,3 Use of proper positions promotes venous drainage from the cranium to keep intracranial pressure from elevating. The head of the client at risk for or with increased intracranial pressure should be positioned so that it is in a neutral, midline position. The head of the bed should be raised to 30 to 45 degrees. The nurse should avoid flexing or extending the client's neck or turning the client's head from side to side.

The nurse is planning care for a client who displays confusion secondary to a neurological problem. Which approaches by the nurse would be helpful in assisting this client? Select all that apply. 1. Providing sensory cues 2. Giving simple, clear directions 3. Providing a stable environment 4. Keeping family pictures at the bedside 5. Encouraging family members to visit at the same time

1,2,3,4 Clients with cognitive impairment from neurological dysfunction respond best to a stable environment that is limited in amount and type of sensory input. The nurse can provide sensory cues and give clear, simple directions in a positive manner. Confusion can be minimized by reducing environmental stimuli (such as television or multiple visitors) and by keeping familiar personal articles (such as family pictures) at the bedside.

The nurse is creating a plan of care for a client with dysphagia following a stroke (brain attack). Which should the nurse include in the plan? Select all that apply. 1. Thicken liquids. 2. Assist the client with eating. 3. Assess for the presence of a swallow reflex. 4. Place the food on the affected side of the mouth. 5. Provide ample time for the client to chew and swallow.

1,2,3,5 Liquids are thickened to prevent aspiration. The nurse should assist the client with eating and place food on the unaffected side of the mouth. The nurse should assess for gag and swallowing reflexes before the client with dysphagia is started on a diet. The client should be allowed ample time to chew and swallow to prevent choking.

The nurse is trying to communicate with a client who had a stroke and has aphasia. Which actions by the nurse would be most helpful to the client? Select all that apply. 1. Speaking to the client at a slower rate 2. Allowing plenty of time for the client to respond 3. Completing the sentences that the client cannot finish 4. Looking directly at the client during attempts at speech 5. Shouting words if it seems as though the client has difficulty understanding

1,2,4 Clients with aphasia after brain attack often fatigue easily and have a short attention span. General guidelines when trying to communicate with the aphasic client include speaking more slowly and allowing adequate response time, listening to and watching attempts to communicate, and trying to put the client at ease with a caring and understanding manner. The nurse would avoid shouting (because the client is not deaf), appearing rushed for a response, and letting family members provide all responses for the client.

The nurse is assigned to care for a client with complete right-sided hemiparesis from a stroke (brain attack). Which characteristics are associated with this condition? Select all that apply. 1. The client is aphasic. 2. The client has weakness on the right side of the body. 3. The client has complete bilateral paralysis of the arms and legs. 4. The client has weakness on the right side of the face and tongue. 5. The client has lost the ability to move the right arm but is able to walk independently. 6. The client has lost the ability to ambulate independently but is able to feed and bathe himself or herself without assistance.

1,2,4 Hemiparesis is a weakness of one side of the body that may occur after a stroke. It involves weakness of the face and tongue, arm, and leg on one side. These clients are also aphasic: unable to discriminate words and letters. They are generally very cautious and get anxious when attempting a new task. Complete bilateral paralysis does not occur in hemiparesis. The client with right-sided hemiparesis has weakness of the right arm and leg and needs assistance with feeding, bathing, and ambulating.

A client with a neurological problem is experiencing hyperthermia. Which measures would be appropriate for the nurse to use in trying to lower the client's body temperature? Select all that apply. 1. Giving tepid sponge baths 2. Applying a hypothermia blanket 3. Covering the client with blankets 4. Administering acetaminophen per protocol 5. Placing ice packs over the client's abdomen and in the axilla and groin

1,2,4 Standard measures to lower body temperature include removing bed covers, providing cool sponge baths, using an electric fan in the room, administering acetaminophen, and placing a hypothermia blanket under the client. Ice packs are not used because they could cause shivering, which increases cellular oxygen demands, with the potential for increased intracranial pressure.

The nurse has just admitted to the nursing unit a client with a basilar skull fracture who is at risk for increased intracranial pressure (ICP). Pending specific health care provider prescriptions, the nurse should plan to place the client in which positions? Select all that apply. 1. Head midline 2. Neck in neutral position 3. Flat, with head turned to the side 4. Head of bed elevated 30 to 45 degrees 5. Head of bed elevated with the neck extended

1,2,4 The client who is at risk for or who has increased ICP should be positioned so that the head is in a neutral, midline position. The nurse should avoid flexing or extending the client's neck or turning the head from side to side. The head of the bed should be raised to 30 to 45 degrees. Use of proper positions promotes venous drainage from the cranium to keep ICP down.

A client with a spinal cord injury is prone to experiencing autonomic dysreflexia. The nurse should include which measures in the plan of care to minimize the risk of occurrence? Select all that apply. 1. Keeping the linens wrinkle-free under the client 2. Preventing unnecessary pressure on the lower limbs 3. Limiting bladder catheterization to once every 12 hours 4. Turning and repositioning the client at least every 2 hours 5. Ensuring that the client has a bowel movement at least once a week

1,2,4 The most frequent cause of autonomic dysreflexia is a distended bladder. Straight catheterization should be done every 4 to 6 hours (catheterization every 12 hours is too infrequent), and urinary catheters should be checked frequently to prevent kinks in the tubing. Constipation and fecal impaction are other causes, so maintaining bowel regularity is important. Ensuring a bowel movement once a week is much too infrequent. Other causes include stimulation of the skin from tactile, thermal, or painful stimuli. The nurse administers care to minimize risk in these areas.

The nurse has determined that a client with a neurological disorder also has difficulty breathing. Which activities would be appropriate components of the care plan for this client? Select all that apply. 1. Keep suction equipment at the bedside. 2. Elevate the head of the bed 30 degrees. 3. Keep the client lying in a supine position. 4. Keep the head and neck in good alignment. 5. Administer prescribed respiratory treatments as needed.

1,2,4,5 The nurse maintains a patent airway for the client with difficulty breathing by keeping the head and neck in good alignment and elevating the head of the bed 30 degrees unless contraindicated. Suction equipment is kept at the bedside if secretions need to be cleared. The client should be kept in a side-lying position whenever possible to minimize the risk of aspiration.

The nurse is planning to put aneurysm precautions in place for a client with a cerebral aneurysm. Which nursing measures would be implemented? Select all that apply. 1. Provide physical aspects of care. 2. Prevent pushing or straining activities. 3. Limit caffeinated coffee to 1 cup per day. 4. Keeping the lights on in the client's room. 5. Maintain the head of the bed at 15 degrees.

1,2,5 Aneurysm precautions include placing the client on bed rest (as prescribed) in a quiet setting. Stimulants such as caffeine and nicotine are prohibited; decaffeinated coffee or tea may be used. Lights are kept dim to minimize environmental stimulation. Any activity that increases the blood pressure or impedes venous return from the brain is prohibited, such as pushing, pulling, sneezing, coughing, or straining. The nurse provides physical care to minimize increases in blood pressure. For the same reason, visitors, radio, television, and reading materials are prohibited or limited.

The nurse is instituting seizure precautions for a client who is being admitted from the emergency department. Which measures should the nurse include in planning for the client's safety? Select all that apply. 1. Padding the side rails of the bed 2. Placing an airway at the bedside 3. Placing the bed in the high position 4. Putting a padded tongue blade at the head of the bed 5. Placing oxygen and suction equipment at the bedside 6. Flushing the intravenous catheter to ensure that the site is patent

1,2,5,6 Seizure precautions may vary from agency to agency, but they generally have some common features. Usually, an airway, oxygen, and suctioning equipment are kept available at the bedside. The side rails of the bed are padded, and the bed is kept in the lowest position. The client has an intravenous access in place to have a readily accessible route if antiseizure medications must be administered, and as part of the routine assessment the nurse should be checking patency of the catheter. The use of padded tongue blades is highly controversial, and they should not be kept at the bedside. Forcing a tongue blade into the mouth during a seizure more likely will harm the client who bites down during seizure activity. Risks include blocking the airway from improper placement, chipping the client's teeth, and subsequent risk of aspirating tooth fragments. If the client has an aura before the seizure, it may give the nurse enough time to place an oral airway before seizure activity begins.

The nurse is caring for a client with an intracranial aneurysm who has been alert. Which signs and symptoms are an early indication that the level of consciousness (LOC) is deteriorating? Select all that apply. 1. Mild drowsiness 2. Drooping eyelids 3. Ptosis of the left eyelid 4. Slight slurring of speech 5. Less frequent spontaneous speech

1,4,5 Early changes in LOC relate to orientation, alertness, and verbal responsiveness. Mild drowsiness, slight slurring of speech, and less frequent spontaneous speech are early signs of decreasing LOC. Ptosis (drooping) of the eyelid is caused by pressure on and dysfunction of cranial nerve III. Once ptosis occurs, it is ongoing; it does not relate to LOC.

The nurse is caring for the client with increased intracranial pressure. The nurse would note which trend in vital signs if the intracranial pressure is rising? 1. Increasing temperature, increasing pulse, increasing respirations, decreasing blood pressure 2. Increasing temperature, decreasing pulse, decreasing respirations, increasing blood pressure A client has clear fluid leaking from the nose following a basilar skull fracture. Which finding would alert the nurse that cerebrospinal fluid is present? 3. Decreasing temperature, decreasing pulse, increasing respirations, decreasing blood pressure 4. Decreasing temperature, increasing pulse, decreasing respirations, increasing blood pressure

2 A change in vital signs may be a late sign of increased intracranial pressure. Trends include increasing temperature and blood pressure and decreasing pulse and respirations. Respiratory irregularities also may occur.

A client was seen and treated in the hospital emergency department for a concussion. The nurse determines that the family needs further teaching if they verbalize to call the health care provider (HCP) for which client sign or symptom? 1. Vomiting 2. Minor headache 3. Difficulty speaking 4. Difficulty awakening

2 A concussion after head injury is a temporary loss of consciousness (from a few seconds to a few minutes) without evidence of structural damage. After concussion, the family is taught to monitor the client and call the HCP or return the client to the emergency department for signs and symptoms such as confusion, difficulty awakening or speaking, one-sided weakness, vomiting, and severe headache. Minor headache is expected.

The nurse is evaluating a function of the limbic system as a part of the neurological status of a client. What should the nurse assess? 1. Experience of pain 2. Affect or emotions 3. Response to verbal stimuli 4. Insight, judgment, and planning

2 Affect and emotions are part of the role of the limbic system and involve both hemispheres of the brain. Pain is a complex experience involving several areas of the central nervous system. The response to verbal stimuli is part of the level of consciousness, which is under the control of the reticular activating system and both cerebral hemispheres. Insight, judgment, and planning are part of the functions of the frontal lobes of the brain in conjunction with association fibers connecting to other areas of the cerebrum.

The nurse has made a judgment that a client who had a craniotomy is experiencing a problem with body image. The nurse develops goals for the client but determines that the client has not met the outcome criteria by discharge if the client performs which action? 1. Wears a turban to cover the incision 2. Indicates that facial puffiness will be a permanent problem 3. Verbalizes that periorbital bruising will disappear over time 4. States an intention to purchase a hairpiece until hair has grown back

2 After craniotomy, clients may experience difficulty with altered personal appearance. The nurse can help by listening to the client's concerns and by clarifying any misconceptions about facial edema, periorbital bruising, and hair loss (all of which are temporary). The nurse can encourage the client to participate in self-grooming and use personal articles of clothing. Finally, the nurse can suggest the use of a turban, followed by a hairpiece, to help the client adapt to the temporary change in appearance.

The student nurse develops a plan of care for a client after a lumbar puncture. The nursing instructor corrects the student if the student documents which incorrect intervention in the plan? 1. Maintain the client in a flat position. 2. Restrict fluid intake for a period of 2 hours. 3. Assess the client's ability to void and move the extremities. 4. Inspect the puncture site for swelling, redness, and drainage.

2 After the lumbar puncture the client remains flat in bed for at least 2 hours, depending on the health care provider's prescriptions. A liberal fluid intake is encouraged to replace the cerebrospinal fluid removed during the procedure, unless contraindicated by the client's condition. The nurse checks the puncture site for redness and drainage and assesses the client's ability to void and move the extremities.

An older client in an acute state of disorientation is brought to the hospital emergency department by the client's daughter. The daughter states that the client was "clear as a bell this morning." The nurse determines from this piece of information that which is an unlikely cause of the disorientation? 1. Hypoglycemia 2. Alzheimer's disease 3. Medication dosage error 4. Impaired circulation to the brain

2 Alzheimer's disease is a chronic disease with progression of memory deficits over time. The situation presented in the question represents an acute problem. Evaluation is necessary to determine whether hypoglycemia, medication use, or impaired cerebral circulation has had a role in causing the client's current symptoms.

The nurse is assessing the client's gait and notes it is unsteady and staggering. Which description should the nurse use when documenting the assessment finding? 1. Spastic 2. Ataxic 3. Festinating 4. Dystrophic or broad-based

2 An ataxic gait is characterized by unsteadiness and staggering. A spastic gait is characterized by stiff, short steps with the legs held together, hip and knees flexed, and toes that catch and drag. A festinating gait is best described as walking on the toes with an accelerating pace. A dystrophic or broad-based gait is seen as waddling, with the weight shifting from side to side and the legs far apart.

The nurse assesses a client who is diagnosed with a stroke (brain attack). On assessment, the client is unable to understand the nurse's commands. Which condition should the nurse document? 1. Occipital lobe impairment 2. Damage to the auditory association areas 3. Frontal lobe and optic nerve tracts damage 4. Difficulty with concept formation and abstraction areas

2 Auditory association and storage areas are located in the temporal lobe and relate to understanding spoken language. The occipital lobe contains areas related to vision. The frontal lobe controls voluntary muscle activity, including speech, and an impairment can result in expressive aphasia. The parietal lobe contains association areas for concept formation, abstraction, spatial orientation, body and object size and shape, and tactile sensation.

A client has a high level of carbon dioxide (CO2) in the bloodstream, as measured by arterial blood gases. The nurse anticipates that which underlying pathophysiology can occur as a result of this elevated CO2? 1. It will cause arteriovenous shunting. 2. It will cause vasodilation of blood vessels in the brain. 3. It will cause blood vessels in the circle of Willis to collapse. 4. It will cause hyperresponsiveness of blood vessels in the brain.

2 CO2 is one of the metabolic end products that can alter the tone of the blood vessels in the brain. High CO2 levels cause vasodilation, which may cause headache, whereas low CO2 levels cause vasoconstriction, which may cause lightheadedness. The statements included in the other options are incorrect effects.

The home care nurse is making extended follow-up visits to a client discharged from the hospital after a moderately severe head injury. The family states that the client is behaving differently than before the accident. The client is more fatigued and irritable and has some memory problems. The client, who was previously very even tempered, is prone to outbursts of temper now. The nurse determines that these behaviors are indicative of which problem? 1. Intracranial pressure changes 2. A long-term sequela of the injury 3. A worsening of the original injury 4. A short-term problem that will resolve in about 1 month

2 Clients with moderate to severe head injury usually have residual physical and cognitive disabilities; these include personality changes, increased fatigue and irritability, mood alterations, and memory changes. The client also may require frequent to constant supervision. The nurse assesses the family's ability to cope and makes appropriate referrals to respite services, support groups, and state or local chapters of the National Head Injury Foundation.

The nurse is admitting a client to the hospital emergency department from a nursing home. The client is unconscious with an apparent frontal head injury. A medical diagnosis of epidural hematoma is suspected. Which question is of the highest priority for the emergency department nurse to ask of the transferring nurse at the nursing home? 1. "When did the injury occur?" 2. "Was the client awake and talking right after the injury?" 3. "What medications has the client received since the fall?" 4. "What was the client's level of consciousness before the injury?"

2 Epidural hematomas frequently are characterized by a "lucid interval" that lasts for minutes to hours, during which the client is awake and talking. After this lucid interval, signs and symptoms progress rapidly, with potentially catastrophic intracranial pressure increase. Epidural hematomas are medical emergencies. It is important for the nurse to assist in the differentiation between epidural hematoma and other types of head injuries.

The nurse has given the client with Bell's palsy instructions on preserving muscle tone in the face and preventing denervation. The nurse determines that the client needs further teaching if the client makes which statements? 1. "I will perform facial exercises." 2. "I will expose my face to cold to decrease the pain." 3. "I will massage my face with a gentle upward motion." 4. "I will wrinkle my forehead, blow out my cheeks, and whistle frequently."

2 Exposure to cold or drafts is avoided in Bell's palsy because it can cause discomfort. Prevention of muscle atrophy with Bell's palsy is accomplished with facial massage, facial exercises, and electrical nerve stimulation. Local application of heat to the face may improve blood flow and provide comfort.

The nurse is trying to help the family of an unconscious client cope with the situation. Which intervention should the nurse plan to incorporate into the care routine for the client and family? 1. Discouraging the family from touching the client 2. Explaining equipment and procedures on an ongoing basis 3. Ensuring adherence to visiting hours to ensure the client's rest 4. Encouraging the family not to "give in" to their feelings of grief

2 Families often need assistance to cope with the illness of a loved one. The nurse should explain all equipment, treatments, and procedures and should supplement or reinforce information given by the health care provider. Family members should be encouraged to touch and speak to the client and to become involved in the client's care to the extent they are comfortable. The nurse should allow the family to stay with the client to the extent possible and should encourage them to eat and sleep adequately to maintain strength. The nurse can help family members of an unconscious client by assisting them to work through their feelings of grief.

The nurse is assessing the function of cranial nerve XII in a client who sustained a stroke. To assess function of this nerve, which action should the nurse ask the client to perform? 1. Extend the arms. 2. Extend the tongue. 3. Turn the head toward the nurse's arm. 4. Focus the eyes on the object held by the nurse.

2 Impairment of cranial nerve XII can occur with a stroke. To assess the function of cranial nerve XII (the hypoglossal nerve), the nurse would assess the client's ability to extend the tongue. The maneuvers noted in the remaining options do not test the function of cranial nerve XII.

The nurse is performing the oculocephalic response (doll's eyes maneuver) on an unconscious client. The nurse turns the client's head and notes movement of the eyes in the same direction as the head. How should the nurse document these findings? 1. Normal 2. Abnormal 3. Insignificant 4. Inconclusive

2 In an unconscious client, eye movements are an indication of brainstem activity and are tested by the oculocephalic response. When the doll's eyes maneuver is intact, the eyes move in the opposite direction when the head is turned. Abnormal responses include movement of the eyes in the same direction as the head and maintenance of a midline position of the eyes when the head is turned. An abnormal response indicates a disruption in the processing of information through the brainstem

The nurse assigned to the care of an unconscious client is making initial daily rounds. On entering the client's room, the nurse observes that the client is lying supine in bed, with the head of the bed elevated approximately 5 degrees. The nasogastric tube feeding is running at 70 mL/hr, as prescribed. The nurse assesses the client and auscultates adventitious breath sounds. Which judgment should the nurse formulate for the client? 1. Impaired nutritional intake 2. Increased risk for aspiration 3. Increased likelihood for injury 4. Susceptibility to fluid volume deficit

2 Increased risk for aspiration is a condition in which an individual is at risk for entry of gastrointestinal (GI) secretions, oropharyngeal secretions, or solids or fluids into tracheobronchial passages. Conditions that place the client at risk for aspiration include reduced level of consciousness, depressed cough and gag reflexes, and feeding via a GI tube. There is no information in the question indicating that the remaining options are a concern.

The nurse is assessing the motor and sensory function of an unconscious client. The nurse should use which technique to test the client's peripheral response to pain? 1.Sternal rub 2.Nail bed pressure 3.Pressure on the orbital rim 4.Squeezing of the sternocleidomastoid muscle

2 Nail bed pressure tests a basic motor and sensory peripheral response. Cerebral responses to pain are tested using a sternal rub, placing upward pressure on the orbital rim, or squeezing the clavicle or sternocleidomastoid muscle.

The nurse is assessing a client's muscle strength and notes that when asked, the client cannot maintain the hands in a supinated position with the arms extended and eyes closed. How should the nurse correctly document this finding on the medical record? 1. Client is demonstrating ataxia. 2. Client is exhibiting pronator drift. 3. Client appears to have nystagmus. 4. Client examination reveals hyperreflexia.

2 Pronator drift occurs when a client cannot maintain the hands in a supinated position with the arms extended and eyes closed. This assessment may be done to detect small changes in muscle strength that might not otherwise be noted. Ataxia is a disturbance in gait. Nystagmus is characterized by fine, involuntary eye movements. It can occur with neurological disease or as a side effect of selected medications. Hyperreflexia is an excessive reflex action.

A client with a traumatic brain injury is able, with eyes closed, to identify a set of keys placed in his or her hands. On the basis of this assessment finding, the nurse determines that there is appropriate function of which lobe of the brain? 1. Frontal 2. Parietal 3. Occipital 4. Temporal

2 The ability to distinguish an object by touch is called stereognosis, which is a function of the right parietal area. The parietal lobe of the brain is responsible for spatial orientation and awareness of sizes and shapes. The left parietal area is responsible for mathematics and right-left orientation. The other lobes of the brain are not responsible for this function.

At the end of the work shift, the nurse is reviewing the respiratory status of a client admitted with a stroke (brain attack) earlier in the day. The nurse determines that the client's airway is patent if which data are identified? 1. Respiratory rate 24 breaths/min, oxygen saturation 94%, breath sounds clear 2. Respiratory rate 18 breaths/min, oxygen saturation 98%, breath sounds clear 3. Respiratory rate 16 breaths/min, oxygen saturation 85%, wheezes bilaterally 4. Respiratory rate 20 breaths/min, oxygen saturation 92%, diminished breath sounds in lung bases

2 The client's airway is most protected if all of the respiratory parameters measured fall within normal limits. Therefore, the respiratory rate should ideally be 16 to 20 breaths/min, the oxygen saturation should be greater than 95%, and the breath sounds should be clear. The correct option is the only one that meets all 3 criteria.

A client is diagnosed with Bell's palsy. The nurse assessing the client expects to note which symptom? 1. A symmetrical smile 2. Difficulty closing the eyelid on the affected side 3. Narrowing of the palpebral fissure on the affected side 4. Paroxysms of excruciating pain in the lips and cheek on the affected side

2 The facial drooping associated with Bell's palsy makes it difficult for the client to close the eyelid on the affected side. A widening of the palpebral fissure (the opening between the eyelids) and an asymmetrical smile are seen with Bell's palsy. Paroxysms of excruciating pain are characteristic of trigeminal neuralgia

The nurse is positioning a client who has increased intracranial pressure. Which position should the nurse avoid? 1. Head midline 2. Head turned to the side 3. Neck in neutral position 4. Head of bed elevated 30 to 45 degrees

2 The head of a client with increased intracranial pressure should be kept in a neutral midline position. The nurse should avoid flexing or extending the client's neck or turning the head from side to side. The head of the bed should be raised to 30 to 45 degrees. Use of proper positions promotes venous drainage from the cranium to keep intracranial pressure down.

A client who suffered a stroke is prepared for discharge from the hospital. The health care provider has prescribed range-of-motion (ROM) exercises for the client's right side. What action should the nurse include in the client's plan of care? 1. Implement ROM exercises to the point of pain for the client. 2. Consider the use of active, passive, or active-assisted exercises in the home. 3. Encourage the client to be dependent on the home care nurse to complete the exercise program. 4. Develop a schedule of ROM exercises every 2 hours while awake even if the client is fatigued.

2 The home care nurse must consider all forms of ROM for the client. Even a client with hemiplegia can participate in some components of rehabilitative care. In addition, the goal in home care nursing is for the client to assume as much self-care and independence as possible. The nurse needs to teach home care measures so that the client becomes self-reliant. The options of performing ROM exercises to the point of pain and performing ROM exercises every 2 hours while the client is awake even if fatigued are incorrect from a physiological standpoint.

The nurse notes that a client who has suffered a brain injury has an adequate heart rate, blood pressure, fluid balance, and body temperature. Based on these clinical findings, the nurse determines that which brain area is functioning properly? 1. Thalamus 2. Hypothalamus 3. Limbic system 4. Reticular activating system

2 The hypothalamus is responsible for autonomic nervous system functions, such as heart rate, blood pressure, temperature, and fluid and electrolyte balance (among others). The thalamus acts as a relay station for sensory and motor information. The limbic system is responsible for emotions. The reticular activating system is responsible for the sleep-wake cycle.

A client has a neurological deficit involving the limbic system. On assessment, which finding is specific to this type of deficit? 1. Is disoriented to person, place, and time 2. Affect is flat, with periods of emotional lability 3. Cannot recall what was eaten for breakfast today 4. Demonstrates inability to add and subtract; does not know who is the president of the United States

2 The limbic system is responsible for feelings (affect) and emotions. Calculation ability and knowledge of current events relate to function of the frontal lobe. The cerebral hemispheres, with specific regional functions, control orientation. Recall of recent events is controlled by the hippocampus.

Which assessment finding should the nurse expect to note in the client hospitalized with a diagnosis of stroke who has difficulty chewing food? 1. Dysfunction of vagus nerve (cranial nerve X) 2. Dysfunction of trigeminal nerve (cranial nerve V) 3. Dysfunction of hypoglossal nerve (cranial nerve XII) 4. Dysfunction of spinal accessory nerve (cranial nerve XI)

2 The motor branch of cranial nerve V is responsible for the ability to chew food. The vagus nerve is active in parasympathetic functions of the autonomic nervous system. The hypoglossal nerve aids in swallowing. The spinal accessory nerve is responsible for shoulder movement, among other things.

A client is newly admitted to the hospital with a diagnosis of stroke (brain attack) manifested by complete hemiplegia. Which item in the medical history of the client should the nurse be most concerned about? 1. Glaucoma 2. Emphysema 3. Hypertension 4. Diabetes mellitus

2 The nurse should be most concerned about emphysema. The respiratory system is the priority in the acute phase of a stroke. The client with a stroke is vulnerable to respiratory complications such as atelectasis and pneumonia. Because the client has complete hemiplegia (is unable to move) and has emphysema, these risks are very significant. Although the other conditions of glaucoma, hypertension, and diabetes mellitus are important, they are not as significant as emphysema.

The nurse is testing the spinal reflexes of a client during neurological assessment. Which assessment by the nurse would help to determine the adequacy of the spinal reflex? 1. Cough reflex 2. Withdrawal reflex 3. Munro-Kellie reflex 4. Accommodation reflex

2 The withdrawal reflex is one of the spinal reflexes. It is an abrupt withdrawal of a body part in response to painful or injurious stimuli. The cough reflex is a brainstem-associated reflex. Accommodation reflex is associated with cranial nerve III and is part of the ocular motor system. Munro-Kellie is not a reflex; it is a doctrine or a hypothesis addressing the cerebral volume relationships among the brain, the cerebrospinal fluid, and intracranial blood and their cumulative impact on intracranial pressure.

A client has sustained damage to Wernicke's area from a stroke (brain attack). On assessment of the client, which sign or symptom would be noted? 1. Difficulty speaking 2. Problem with understanding language 3. Difficulty controlling voluntary motor activity 4. Problem with articulating events from the remote past

2 Wernicke's area consists of a small group of cells in the temporal lobe whose function is the understanding of language. Damage to Broca's area is responsible for aphasia. The motor cortex in the precentral gyrus controls voluntary motor activity. The hippocampus is responsible for the storage of memory.

The nurse is caring for a client who was admitted for a stroke (brain attack) of the temporal lobe. Which clinical manifestations should the nurse expect to note in the client? 1. The client will be unable to recall past events. 2. The client will have difficulty understanding language. 3. The client will demonstrate difficulty articulating words. 4. The client will have difficulty moving 1 side of the body.

2 Wernicke's area consists of a small group of cells in the temporal lobe, the function of which is the understanding of language. The hippocampus is responsible for the storage of memory (the client will be unable to recall past events). Damage to Broca's area is responsible for aphasia (the client will demonstrate difficulty articulating words). The motor cortex in the precentral gyrus controls voluntary motor activity (the client will have difficulty moving one side of the body).

The nurse develops a plan of care for a client with a brain aneurysm who will be placed on aneurysm precautions. Which interventions should be included in the plan? Select all that apply. 1. Leave the lights on in the client's room at night. 2. Place a blood pressure cuff at the client's bedside. 3. Close the shades in the client's room during the day. 4. Allow the client to drink 1 cup of caffeinated coffee a day. 5. Allow the client to ambulate 4 times a day with assistance.

2,3 Aneurysm precautions include placing the client on bed rest in a quiet setting. The use of lights is kept to a minimum to prevent environmental stimulation. The nurse should monitor the blood pressure and note any changes that could indicate rupture. Any activity, such as pushing, pulling, sneezing, or straining, that increases the blood pressure or impedes venous return from the brain is prohibited. The nurse provides physical care to minimize increases in blood pressure. Visitors, radio, television, and reading materials are restricted or limited. Stimulants, such as nicotine and coffee and other caffeine-containing products, are prohibited. Decaffeinated coffee or tea may be used.

A client who has had a stroke (brain attack) has residual dysphagia. When a diet prescription is initiated, the nurse should take which actions? Select all that apply. 1. Giving the client thin liquids 2. Thickening liquids to the consistency of oatmeal 3. Placing food on the unaffected side of the mouth 4. Allowing plenty of time for chewing and swallowing 5. Leave the client alone so that the client will gain independence by feeding self

2,3,4 The client with dysphagia is started on a diet only after the gag and swallow reflexes have returned. The client is assisted with meals as needed and is given ample time to chew and swallow. Food is placed on the unaffected side of the mouth. Liquids are thickened to avoid aspiration. The client is not left alone because of the risk of aspiration.

The nurse is administering mouth care to an unconscious client. The nurse should perform which actions in the care of this person? Select all that apply. 1. Use products that contain alcohol. 2. Position the client on his or her side. 3. Brush the teeth with a small, soft toothbrush. 4. Cleanse the mucous membranes with soft sponges. 5. Use lemon glycerin swabs when performing mouth care.

2,3,4 The unconscious client is positioned on the side during mouth care to prevent aspiration. The teeth are brushed at least twice daily with a small toothbrush. The gums, tongue, roof of the mouth, and oral mucous membranes are cleansed with soft sponges to avoid encrustation and infection. The lips are coated with water-soluble lubricant to prevent drying, cracking, and encrustation. The use of products with alcohol and lemon glycerin swabs should be avoided because they have a drying effect.

The nurse is caring for a client who is at risk for increased intracranial pressure (ICP) after a stroke. Which activities performed by the nurse will assist with preventing increases in ICP? Select all that apply. 1. Clustering nursing activities 2. Hyperoxygenating before suctioning 3. Maintaining 20 degree flexion of the knees 4. Maintaining the head and neck in midline position 5. Maintaining the head of the bed (HOB) at 30 degrees elevation

2,4,5 Measures aimed at preventing increased ICP in the poststroke client include hyperoxgenating before suctioning to avoid transient hypoxemia and resultant ICP elevation from dilation of cerebral arteries; maintaining the head in a midline, neutral position to help promote venous drainage from the brain; and keeping the HOB elevated to between 25 and 30 degrees to prevent a decreased blood flow to the brain. Clustering activities can be stressful for the client and increase ICP. Maintaining 20 degree flexion of the knees increases intraabdominal pressure and consequently ICP.

A client with a neurological impairment experiences urinary incontinence. Which nursing action would be most helpful in assisting the client to adapt to this alteration? 1. Using adult diapers 2. Inserting a Foley catheter 3. Establishing a toileting schedule 4. Padding the bed with an absorbent cotton pad

3 A bladder retraining program, such as use of a toileting schedule, may be helpful to clients experiencing urinary incontinence. A Foley catheter should be used only when necessary because of the associated risk of infection. Use of diapers or pads is the least acceptable alternative because of the risk of skin breakdown.

The nurse is planning discharge teaching for a client started on acetazolamide for a supratentorial lesion. Which information about the primary action of the medication should be included in the client's education? 1. It will prevent hypertension. 2. It will prevent hyperthermia. 3. It decreases cerebrospinal fluid production. 4. It maintains adequate blood pressure for cerebral perfusion.

3 Acetazolamide is a carbonic anhydrase inhibitor and a diuretic. It is used in the client with or at risk for increased intracranial pressure to decrease cerebrospinal fluid production. The remaining options are not actions of this medication.

The nurse is caring for a client who has undergone a craniotomy and has a supratentorial incision. The nurse should place the client in which position postoperatively? 1. Head of bed flat, head and neck midline 2. Head of bed flat, head turned to the nonoperative side 3. Head of bed elevated 30 to 45 degrees, head and neck midline 4. Head of bed elevated 30 to 45 degrees, head turned to the operative side

3 After supratentorial surgery, the head is kept at a 30- to 45-degree angle. The head and neck should not be angled either anteriorly or laterally but rather should be kept in a neutral (midline) position. This promotes venous return through the jugular veins, which will help prevent a rise in intracranial pressure.

The nurse is preparing to care for a client after a lumbar puncture. The nurse should plan to place the client in which best position following the procedure? 1. Prone in semi Fowler's position 2. Supine in semi Fowler's position 3. Prone with a small pillow under the abdomen 4. Lateral with the head slightly lower than the rest of the body

3 After the procedure, the client assumes a flat position. If the client is able, a prone position with a pillow under the abdomen is the best position. This position helps reduce cerebrospinal fluid leakage and decreases the likelihood of post-lumbar puncture headache. The remaining options are incorrect.

The nurse is assessing a client with a brainstem injury. In addition to obtaining the client's vital signs and determining the Glasgow Coma Scale score, what priority intervention should the nurse plan to implement? 1. Check cranial nerve functioning. 2. Determine the cause of the accident. 3. Draw blood for arterial blood gas analysis. 4. Perform a pulmonary wedge pressure measurement.

3 Assessment should be specific to the area of the brain involved. The respiratory center is located in the brainstem. Assessing the respiratory status is the priority for a client with a brainstem injury. The actions in the remaining options are not priorities, although they may be a component in the assessment process, depending on the injury and client condition.

The nurse in the neurological unit is caring for a client who was in a motor vehicle crash and sustained a blunt head injury. On assessment of the client, the nurse notes the presence of bloody drainage from the nose. Which nursing action is most appropriate? 1. Insert nasal packing. 2. Document the findings. 3. Contact the health care provider (HCP). 4. Monitor the client's blood pressure and check for signs of increased intracranial pressure.

3 Bloody or clear drainage from either the nasal or the auditory canal after head trauma could indicate a cerebrospinal fluid leak. The appropriate nursing action is to notify the HCP, because this finding requires immediate intervention. The remaining options are inappropriate nursing actions in this situation.

The nurse is reviewing the medical records of a client admitted to the nursing unit with a diagnosis of a thrombotic brain attack (stroke). The nurse would expect to note that which is documented in the assessment data section of the record? 1. Sudden loss of consciousness occurred. 2. Signs and symptoms occurred suddenly. 3. The client experienced paresthesias a few days before admission to the hospital. 4. The client complained of a severe headache, which was followed by sudden onset of paralysis.

3 Cerebral thrombosis does not occur suddenly. In the few hours or days preceding a thrombotic brain attack (stroke), the client may experience a transient loss of speech, hemiplegia, or paresthesias on 1 side of the body. Signs and symptoms of thrombotic brain attack (stroke) vary but may include dizziness, cognitive changes, or seizures. Headache is rare, but some clients with stroke (brain attack) experience signs and symptoms similar to those of cerebral embolism or intracranial hemorrhage.

The nurse is conducting home visits with a head-injured client with residual cognitive deficits. The client has problems with memory, has a shortened attention span, is easily distracted, and processes information slowly. The nurse plans to talk with the primary health care provider about referring the client to which professional? 1. A psychologist 2. A social worker 3. A neuropsychologist 4. A vocational rehabilitation specialist

3 Clients with cognitive deficits after head injury may benefit from referral to a neuropsychologist, who specializes in evaluating and treating cognitive problems. The neuropsychologist plans an individual program of therapy and initiates counseling to help the client reach maximal potential. The neuropsychologist works in collaboration with other disciplines that are involved in the client's care and rehabilitation. The remaining options are incorrect because these health care workers do not specialize in evaluating and treating cognitive problems.

To promote optimal cerebral tissue perfusion in the postoperative phase following cranial surgery, the nurse should place the client with an incision in the anterior or middle fossa, in which position? 1. 15 degrees of Trendelenburg's 2. Side-lying with the head of the bed flat 3. With the head of the bed elevated at least 30 degrees 4. With the head of the bed elevated no more than 10 degrees

3 Correct positioning of the client following cranial surgery is important to avoid increased intracranial pressure and to promote optimal cerebral tissue perfusion. The surgeon's prescription for positioning is always followed. The client with an incision in the anterior or middle fossa should be positioned with the head of bed (HOB) elevated at least 30 degrees. If the incision is in the posterior fossa or burr holes have been made, the client is positioned flat, or with the HOB elevated no more than 10 to 15 degrees. If a craniectomy (bone flap) is performed, the client should not be positioned to the operative side. Trendelenburg's position is contraindicated in the postoperative phase following cranial surgery.

The nurse is assisting the neurologist in performing an assessment on a client who is unconscious after sustaining a head injury. The nurse understands that the neurologist would avoid performing the oculocephalic response (doll's eyes maneuver) if which condition is present in the client? 1. Dilated pupils 2. Lumbar trauma 3. A cervical cord injury 4. Altered level of consciousness

3 In an unconscious client, eye movements are an indication of brainstem activity and are tested by the oculocephalic response. When the doll's eyes maneuver is intact, the eyes move in the opposite direction when the head is turned. Abnormal responses include movement of the eyes in the same direction as that for the head and maintenance of a midline position of the eyes when the head is turned. An abnormal response indicates a disruption in the processing of information through the brainstem. Contraindications to performing this test include cervical-level spinal cord injuries and severely increased intracranial pressure.

The nurse is caring for a client with a neurological deficit involving the hippocampus. On assessment of the client, which signs and symptoms would most likely be noted? 1. Disoriented to client, place, and time 2. Affect flat, with periods of emotional lability 3. Cannot recall what was eaten for breakfast today 4. Unable to add and subtract; does not know who is president

3 Recall of recent events and the storage of memories are controlled by the hippocampus, which is a limbic system structure. The cerebral hemispheres, with specific regional functions, control orientation. The limbic system, overall, is responsible for feelings, affect, and emotions. Calculation ability and knowledge of current events are under the control of the frontal lobes of the cerebrum.

The nurse is evaluating the neurological signs of a client in spinal shock following spinal cord injury. Which observation indicates that spinal shock persists? 1. Hyperreflexia 2. Positive reflexes 3. Flaccid paralysis 4. Reflex emptying of the bladder

3 Resolution of spinal shock is occurring when there is return of reflexes (especially flexors to noxious cutaneous stimuli), a state of hyperreflexia rather than flaccidity, and reflex emptying of the bladder.

The nurse is evaluating the status of a client who had a craniotomy 3 days ago. Which assessment finding would indicate that the client is developing meningitis as a complication of surgery? 1. A negative Kernig's sign 2. Absence of nuchal rigidity 3. A positive Brudzinski's sign 4. A Glasgow Coma Scale score of 15

3 Signs of meningeal irritation compatible with meningitis include nuchal rigidity, a positive Brudzinski's sign, and positive Kernig's sign. Nuchal rigidity is characterized by a stiff neck and soreness, which is especially noticeable when the neck is flexed. Kernig's sign is positive when the client feels pain and spasm of the hamstring muscles when the leg is fully flexed at the knee and hip. Brudzinski's sign is positive when the client flexes the hips and knees in response to the nurse gently flexing the head and neck onto the chest. A Glasgow Coma Scale score of 15 is a perfect score and indicates that the client is awake and alert, with no neurological deficits.

The client with a head injury opens eyes to sound, has no verbal response, and localizes to painful stimuli when applied to each extremity. How should the nurse document the Glasgow Coma Scale (GCS) score? 1. GCS = 3 2. GCS = 6 3. GCS = 9 4. GCS = 11

3 The GCS is a method for assessing neurological status. The highest possible GCS score is 15. A score lower than 8 indicates that coma is present. Motor response points are as follows: Obeys a simple response = 6; Localizes painful stimuli = 5; Normal flexion (withdrawal) = 4; Abnormal flexion (decorticate posturing) = 3; Extensor response (decerebrate posturing) = 2; No motor response to pain = 1. Verbal response points are as follows: Oriented = 5; Confused conversation = 4; Inappropriate words = 3; Responds with incomprehensible sounds = 2; No verbal response = 1. Eye opening points are as follows: Spontaneous = 4; In response to sound = 3; In response to pain = 2; No response, even to painful stimuli = 1. Using the GCS, a score of 3 is given when the client opens the eyes to sound. Localization to pain is scored as 5. When there is no verbal response the score is 1. The total score is then equal to 9.

A client is somewhat nervous about undergoing magnetic resonance imaging (MRI). Which statement by the nurse would provide the most reassurance to the client about the procedure? 1. "The MRI machine is a long, narrow, hollow tube and may make you feel somewhat claustrophobic." 2. "You will be able to eat before the procedure unless you get nauseated easily. If so, you should eat lightly." 3. "Even though you are alone in the scanner, you will be in voice communication with the technologist at all times during the procedure." 4. "It is necessary to remove any metal or metal-containing objects before having the MRI done to avoid the metal being drawn into the magnetic field."

3 The MRI scanner is a hollow tube that gives some clients a feeling of claustrophobia. Metal objects must be removed before the procedure so that they are not drawn into the magnetic field. The client may eat and may take all prescribed medications before the procedure. If a contrast medium is used, the client may wish to eat lightly if he or she has a tendency to become nauseated easily. The client lies supine on a padded table that moves into the imager. The client must lie still during the procedure. The imager makes tapping noises during the scanning. The client is alone in the imager, but the nurse can reassure the client that the technologist will be in voice communication with the client at all times during the procedure.

A client has dysfunction of the cochlear division of the vestibulocochlear nerve (cranial nerve VIII). The nurse should determine that the client is adequately adapting to this problem if he or she states a plan to obtain which item? 1. A walker 2. Eyeglasses 3. A hearing aid 4. A bath thermometer

3 The cochlear division of cranial nerve VIII is responsible for hearing. Clients with hearing difficulty may benefit from the use of a hearing aid. The vestibular portion of this nerve controls equilibrium; difficulty with balance caused by dysfunction of this division could be addressed with use of a walker. Eyeglasses would correct visual problems (cranial nerve II); a bath thermometer would be of use to clients with sensory deficits of peripheral nerves, such as with diabetic neuropathy.

At 8:00 a.m., A client who has had a stroke (brain attack) was awake and alert with vital signs of temperature 98°F (37.2°C) orally, pulse 80 beats/min, respirations 18 breaths/min, and blood pressure 138/80 mm Hg. At noon, the client is confused and only responsive to tactile stimuli, and vital signs are temperature 99°F (36.7°C) orally, pulse 62 beats/min, respirations 20 breaths/min, and blood pressure 166/72 mm Hg. The nurse should take which action? 1. Reorient the client. 2. Retake the vital signs. 3. Call the health care provider (HCP). 4. Administer an antihypertensive PRN (as needed).

3 The important nursing action is to call the HCP. The deterioration in neurological status, decreasing pulse, and increasing blood pressure with a widening pulse pressure all indicate that the client is experiencing increased intracranial pressure, which requires immediate treatment to prevent further complications and possible death. The nurse should retake the vital signs and reorient the client to surroundings. If the client's blood pressure falls within parameters for PRN antihypertensive medication, the medication also should be administered. However, options 1, 2, and 4 are secondary nursing actions.

A client has suffered a head injury affecting the occipital lobe of the brain. What is the focus of the nurse's immediate assessment? 1. Taste 2. Smell 3. Vision 4. Hearing

3 The occipital lobe is responsible for reception of vision and contains visual association areas. This area of the brain helps the individual to visually recognize and understand the surroundings. The other senses listed are not a function of the occipital lobe.

A client is anxious about an upcoming diagnostic procedure. The client's pupils are dilated, and the respiratory rate, heart rate, and blood pressure are increased from baseline. The nurse determines that the client's clinical manifestations are due to what type of physiologic response? 1. Vagal 2. Peripheral nervous system 3. Sympathetic nervous system 4. Parasympathetic nervous system

3 The sympathetic nervous system is responsible for the so-called fight or flight response, which is characterized by dilated pupils, increases in heart rate and cardiac output, and increases in respiratory rate and blood pressure. The sympathetic nervous system response affects some type of change in most systems of the body. The responses stated in the other options do not produce these effects.

The nurse overhears a neurologist saying that a client has an aneurysm located in the circle of Willis. The nurse understands that which blood vessels are part of the circle of Willis? Select all that apply. 1. Basilar artery 2. Vertebral artery 3. Anterior cerebral artery 4. Internal carotid arteries 5. Posterior cerebral artery

3,4,5 The circle of Willis is a ring of blood vessels located at the base of the brain. It is referred to as the anterior circulation to the brain and is composed of the anterior and middle cerebral arteries, posterior cerebral arteries, posterior communicating arteries, internal carotid arteries, and anterior communicating branches. The basilar artery and vertebral artery are not part of the circle of Willis. Rather, they are part of the vertebral-basilar system, which is known as the posterior circulation to the brain. Other parts of the posterior circulation are the posterior inferior cerebellar artery and the spinal arteries.

A client with a traumatic closed head injury shows signs of secondary brain injury. What are some manifestations of secondary brain injury? Select all that apply. 1. Fever 2. Seizures 3. Hypoxia 4. Ischemia 5. Hypotension 6. Increased intracranial pressure (ICP)

3,4,5,6 Secondary brain injury can occur several hours to days after the initial brain injury and is a major concern when managing brain trauma. Nursing management of the client with an acute intracranial problem must include management of secondary injury. Manifestations of secondary injury includes hypoxia, ischemia, hypotension, and increased ICP that follows primary injury. It does not include fever or seizures.

A client had a transsphenoidal resection of the pituitary gland. The nurse notes drainage on the nasal dressing. Suspecting cerebrospinal fluid (CSF) leakage, the nurse should look for drainage that is of which characteristic? 1. Serosanguineous only 2. Bloody with very small clots 3. Sanguineous only with no clot formation 4. Serosanguineous, surrounded by clear to straw-colored fluid

4 CSF leakage after cranial surgery may be detected by noting drainage that is serosanguineous (from the surgery) and surrounded by an area of clear or straw-colored drainage. The typical appearance of CSF drainage is that of a "halo." The nurse also would further verify actual CSF drainage by testing the drainage for glucose, which would be positive.

The nurse is caring for a client with bacterial meningitis. The nurse should anticipate that an antibiotic with which characteristics will be prescribed for the client? 1. One that has a long half-life 2. One that acts within minutes to hours 3. One that can be easily excreted in the urine 4. One that is able to cross the blood-brain barrier

4 A primary consideration regarding medications to treat bacterial meningitis is the ability of the medication to cross the blood-brain barrier. If the medication cannot cross, it will not be effective. The duration, onset, and excretion of the medication are also of general concern but apply to all medications and not specifically to those that are used to treat meningitis.

A client recovering from a head injury is participating in care. The nurse determines that the client understands measures to prevent elevations in intracranial pressure if the nurse observes the client doing which activity? 1.Blowing the nose 2.Isometric exercises 3.Coughing vigorously 4.Exhaling during repositioning

4 Activities that increase intrathoracic and intraabdominal pressures cause an indirect elevation of the intracranial pressure. Some of these activities include isometric exercises, Valsalva's maneuver, coughing, sneezing, and blowing the nose. Exhaling during activities such as repositioning or pulling up in bed opens the glottis, which prevents intrathoracic pressure from rising.

The nurse is assessing fluid balance in a client who has undergone a craniotomy. The nurse should assess for which finding as a sign of overhydration, which would aggravate cerebral edema? 1. Unchanged weight 2. Shift intake 950 mL, output 900 mL 3. Blood urea nitrogen (BUN) 10 mg/dL (3.6 mmol/L) 4. Serum osmolality 280 mOsm/kg H2O (280 mmol/kg)

4 After craniotomy the goal is to keep the serum osmolality on the high side of normal to minimize excess body water and control cerebral edema. The normal serum osmolality is 285 to 295 mOsm/kg H2O (285 to 295 mmol/kg). A higher value indicates dehydration; a lower value indicates overhydration. Stable weight indicates that there is neither fluid excess nor fluid deficit. A difference of 50 mL in intake and output for an 8-hour shift is insignificant. The BUN of 10 mg/dL (3.6 mmol/L) is within normal range and does not indicate overhydration or underhydration.

The nurse is preparing to care for a client who had a supratentorial craniotomy. The nurse should plan to place the client in which position? 1. Prone 2. Supine 3. Side-lying 4. Semi Fowler's

4 After supratentorial surgery (surgery above the tentorium of the brain), the head of the client's bed usually is elevated 30 degrees to promote venous outflow through the jugular veins. Prone, supine, and side-lying denote incorrect positions after this surgery, and these positions could result in edema at the surgical site and increased intracranial pressure. The health care provider's prescriptions are always followed with regard to positioning the client.

A postoperative craniotomy client who sustained a severe head injury is admitted to the neurological unit. What nursing intervention is necessary for this client? 1. Take and record vital signs every 4 to 8 hours. 2. Prophylactically hyperventilate during the first 24 hours. 3. Treat a central fever with the administration of antipyretic medications such as acetaminophen. 4. Keep the head of the bed elevated at least 30 degrees, and position the client to avoid extreme flexion or extension of the neck and head.

4 Avoiding extreme flexion and extension of the neck can enhance venous drainage and help prevent increased intracranial pressure. As a general rule, hyperventilation is avoided during the first 24 hours postoperatively because it may produce ischemia caused by cerebral vasoconstriction. Vital signs need to be taken and recorded at least every 1 to 2 hours. Central fevers caused by hypothalamic damage respond better to cooling (hypothermia blankets, sponge baths) than to the administration of antipyretic medications.

The nurse is caring for a client with intracranial pressure (ICP) monitoring. Which intervention is appropriate to include in the plan of care? 1. Place the client in Sims' position. 2. Change the drainage tubing every 48 hours. 3. Level the transducer at the lowest point of the ear. 4. Use strict aseptic technique when touching the monitoring system.

4 Because there is a foreign body embedded in the client's brain, vigilant aseptic technique should be implemented. Sims' is a side-lying, flat position. With a client who has increased ICP, the head of the bed should be elevated at least 30 degrees to improve jugular outflow. The drainage tubing should not be routinely changed. It should remain for the duration of the monitoring. To obtain accurate ICP pressure readings, the transducer is zeroed at the level of the foramen of Monro, which is approximated by placing the transducer 1 inch above the level of the ear. Serial ICP readings should be done with the client's head in the same position.

The nurse is assisting with caloric testing of the oculovestibular reflex in an unconscious client. Cold water is injected into the left auditory canal. The client exhibits eye conjugate movements toward the left, followed by eye movement back to midline. The nurse understands that this finding indicates which situation? 1. Brain death 2. A cerebral lesion 3. A temporal lesion 4. An intact brainstem

4 Caloric testing provides information about differentiating between cerebellar and brainstem lesions. After determining patency of the ear canal, cold or warm water is injected into the auditory canal. A normal response that indicates intact function of cranial nerves III, VI, and VIII is conjugate eye movements toward the side being irrigated, followed by eye movement back to midline. Absent or dysconjugate eye movements indicate brainstem damage.

The nurse is performing an assessment on a client with a diagnosis of thrombotic stroke (brain attack). Which assessment question would elicit data specific to this type of stroke? 1. "Have you had any headaches in the past few days?" 2. "Have you recently been having difficulty with seeing at nighttime?" 3. "Have you had any sudden episodes of passing out in the past few days?" 4. "Have you had any numbness or tingling or paralysis-type feelings in any of your extremities recently?"

4 Cerebral thrombosis (thrombotic stroke) does not occur suddenly. In the few days or hours preceding the thrombotic stroke, the client may experience a transient loss of speech, hemiparesis, or paresthesias on 1 side of the body. Signs and symptoms of this type of stroke vary but may also include dizziness, cognitive changes, or seizures. Headache is rare, but some clients with stroke experience signs and symptoms similar to those of cerebral embolism or intracranial hemorrhage. The client does not complain of difficulty with night vision as part of this clinical problem. In addition, most clients do not have repeated episodes of loss of consciousness.

The nurse is assessing the adaptation of a client to changes in functional status after a stroke (brain attack). Which observation indicates to the nurse that the client is adapting most successfully? 1. Gets angry with family if they interrupt a task 2. Experiences bouts of depression and irritability 3. Has difficulty with using modified feeding utensils 4. Consistently uses adaptive equipment in dressing self

4 Clients are evaluated as coping successfully with lifestyle changes after a stroke if they make appropriate lifestyle alterations, use the assistance of others, and have appropriate social interactions. Options 1 and 2 are not adaptive behaviors; option 3 indicates a not yet successful attempt to adapt.

The client has an impairment of cranial nerve II. Specific to this impairment, what should the nurse plan to do to ensure client safety? 1. Speak loudly to the client. 2. Test the temperature of the shower water. 3. Check the temperature of the food on the dietary tray. 4. Provide a clear path for ambulation without obstacles.

4 Cranial nerve II is the optic nerve, which governs vision. The nurse can provide safety for the visually impaired client by clearing the path of obstacles when ambulating. Speaking loudly may help overcome a deficit of cranial nerve VIII (vestibulocochlear). Testing the shower water temperature would be useful if there was an impairment of peripheral nerves. Cranial nerves VII (facial) and IX (glossopharyngeal) control taste from the anterior two thirds and posterior third of the tongue, respectively.

The nurse is caring for a client after a craniotomy and monitors the client for signs of increased intracranial pressure (ICP). Which finding, if noted in the client, would indicate an early sign of increased ICP? 1. Confusion 2. Bradycardia 3. Sluggish pupils 4. A widened pulse pressure

4 Early manifestations of increased ICP are subtle and often may be transient, lasting for only a few minutes in some cases. These early clinical manifestations include episodes of confusion, drowsiness, and slight pupillary and breathing changes. Later manifestations include a further decrease in the level of consciousness, a widened pulse pressure, and bradycardia. Cheyne-Stokes respiratory pattern, or a hyperventilation respiratory pattern, and pupillary sluggishness and dilatation appear in the late stages.

The nurse has a prescription to begin aneurysm precautions for a client with a subarachnoid hemorrhage secondary to aneurysm rupture. The nurse would plan to incorporate which intervention in controlling the environment for this client? 1. Keep the window blinds open. 2. Turn on a small spotlight above the client's head. 3. Make sure the door to the room is open at all times. 4. Prohibit or limit the use of a radio or television and reading.

4 Environmental stimuli are kept to a minimum with subarachnoid precautions to prevent or minimize increases in intracranial pressure. For this reason, lighting is reduced by closing window blinds and keeping the door to the client's room shut. Overhead lighting also is avoided for the same reason. The nurse prohibits television, radio, and reading unless this is so stressful for the client that it would be counterproductive. In that instance, minimal amounts of stimuli by these means are allowed with approval of the health care provider.

The nurse has given suggestions to a client with trigeminal neuralgia about strategies to minimize episodes of pain. The nurse determines that the client needs further teaching if the client makes which statement? 1. "I will wash my face with cotton pads." 2. "I'll have to start chewing on my unaffected side." 3. "I should rinse my mouth if toothbrushing is painful." 4. "I'll try to eat my food either very warm or very cold."

4 Facial pain can be minimized by using cotton pads to wash the face and using room temperature water. The client should chew on the unaffected side of the mouth, eat a soft diet, and take in foods and beverages at room temperature. If brushing the teeth triggers pain, an oral rinse after meals may be helpful instead.

The nurse is creating a plan of care for a client with a stroke (brain attack) who has global aphasia. The nurse should incorporate communication strategies into the plan of care because of which expected characteristic of the client's speech? 1. Intact 2. Rambling 3. Characterized by literal paraphasia 4. Associated with poor comprehension

4 Global aphasia is a condition in which the affected person has few language skills as a result of extensive damage to the left hemisphere. The speech is nonfluent and is associated with poor comprehension and limited ability to name objects or repeat words. The client with conduction aphasia has difficulty repeating words spoken by another, and speech is characterized by literal paraphasia with intact comprehension. The client with Wernicke's aphasia may exhibit a rambling type of speech.

The nurse is creating a plan of care for a client with a stroke (brain attack) who has right homonymous hemianopsia. Which should the nurse include in the plan of care for the client? 1. Place an eye patch on the left eye. 2. Place personal articles on the client's right side. 3. Approach the client from the right field of vision. 4. Instruct the client to turn the head to scan the right visual field.

4 Homonymous hemianopsia is a loss of half of the visual field. The nurse instructs the client to scan the environment and stands within the client's intact field of vision. The nurse should not patch the eye because the client does not have double vision. The client should have objects placed in the intact fields of vision, and the nurse should approach the client from the intact side.

The nurse is creating a plan of care for a client with a diagnosis of stroke (brain attack) with anosognosia. To meet the needs of the client with this deficit, the nurse should include activities that will achieve which outcome? 1. Encourage communication. 2. Provide a consistent daily routine. 3. Promote adequate bowel elimination. 4. Increase the client's awareness of the affected side.

4 In anosognosia, the client exhibits neglect of the affected side of the body. The nurse will plan care activities that remind the client to perform actions that require looking at the affected arm or leg, as well as activities that will increase the client's awareness of the affected side. The remaining options are not associated with this deficit.

The nurse is creating a plan of care for a client with a diagnosis of stroke (brain attack). On reviewing the client's record, the nurse notes an assessment finding of anosognosia. The nursing care plan should address which manifestation related to this finding? 1. The client will be easily fatigued. 2. The client will have difficulty speaking. 3. The client will have difficulty swallowing. 4. The client will exhibit neglect of the affected side.

4 In anosognosia, the client neglects the affected side of the body. The client either may ignore the presence of the affected side (often creating a safety hazard as a result of potential injuries) or may state that the involved arm or leg belongs to someone else. The remaining options are not associated with anosognosia.

The nurse is assessing the client's level of consciousness and documents that the client has delirium. On the basis of this documentation, the nurse should determine that there is damage to which area of the nervous system? 1. Temporal lobe and frontal lobe 2. Hippocampus and frontal lobe 3. Limbic system and cerebral hemispheres 4. Reticular activating system and cerebral hemispheres

4 Insomnia, agitation, mania, and delirium are caused by excessive arousal of the reticular activating system in conjunction with the cerebral hemispheres. The temporal lobe, hippocampus, and frontal lobe are responsible for memory. The limbic system is responsible for feelings and affect.

A client has clear fluid leaking from the nose following a basilar skull fracture. Which finding would alert the nurse that cerebrospinal fluid is present? 1.Fluid is clear and tests negative for glucose. 2.Fluid is grossly bloody in appearance and has a pH of 6. 3.Fluid clumps together on the dressing and has a pH of 7. 4.Fluid separates into concentric rings and tests positive for glucose.

4 Leakage of cerebrospinal fluid (CSF) from the ears or nose may accompany basilar skull fracture. CSF can be distinguished from other body fluids because the drainage will separate into bloody and yellow concentric rings on dressing material, called a halo sign. The fluid also tests positive for glucose.

The nurse in the neurological unit is caring for a client with a supratentorial lesion. The nurse assesses which measurement as the most critical index of central nervous system (CNS) dysfunction? 1. Temperature 2. Blood pressure 3. Ability to speak 4. Level of consciousness

4 Level of consciousness is the most critical index of CNS dysfunction. Changes in level of consciousness can indicate clinical improvement or deterioration. Although blood pressure, temperature, and ability to speak may be components of the assessment, the client's level of consciousness is the most critical index of CNS dysfunction.

The nurse is caring for a client with a diagnosis of right (nondominant) hemispheric stroke. The nurse notes that the client is alert and oriented to time and place. On the basis of these assessment findings, the nurse should make which interpretation? 1. Had a very mild stroke 2. Most likely suffered a transient ischemic attack 3. May have difficulty with language abilities only 4. Is likely to have perceptual and spatial disabilities

4 The client with a right (nondominant) hemispheric stroke may be alert and oriented to time and place. These signs of apparent wellness often suggest that the client is less disabled than is the case. However, impulsivity and confusion in carrying out activities may be very real problems for these clients as a result of perceptual and spatial disabilities. The right hemisphere is considered specialized in sensory-perceptual and visual-spatial processing and awareness of body space. The left hemisphere is dominant for language abilities.

A client with a traumatic brain injury is on mechanical ventilation. The nurse promotes normal intracranial pressure (ICP) by ensuring that the client's arterial blood gas (ABG) results are within which ranges? 1. PaO2 60 to 100 mm Hg (60 to 100 mm Hg), PaCo2 25 to 30 mm Hg (25 to 30 mm Hg) 2. PaO2 60 to 100 mm Hg (60 to 100 mm Hg), PaCo2 30 to 35 mm Hg (30 to 35 mm Hg) 3. PaO2 80 to 100 mm Hg (80 to 100 mm Hg), PaCo2 25 to 30 mm Hg (25 to 30 mm Hg) 4. PaO2 80 to 100 mm Hg (80 to 100 mm Hg), PaCo2 35 to 38 mm Hg (35 to 38 mm Hg)

4 The goal is to maintain the partial pressure of arterial carbon dioxide (PaCo2) at 35 to 38 mm Hg (35 to 38 mm Hg). Carbon dioxide is a very potent vasodilator that can contribute to increases in ICP. The PaO2 is not allowed to fall below 80 mm Hg (80 mm Hg), to prevent cerebral vasodilation from hypoxemia, which can also result in an increase in ICP. Therefore, the remaining options are incorrect.

The nurse is caring for a client who has just been admitted to the hospital with a diagnosis of a hemorrhagic stroke. The nurse should place the client in which position? 1. Prone 2. Supine 3. Semi Fowler's with the hip and the neck flexed 4. Head of the bed elevated 30 degrees with the head in midline position

4 The health care provider's prescriptions are always followed with regard to positioning the client after stroke. Clients with hemorrhagic stroke usually have the head of the bed elevated to 30 degrees to reduce intracranial pressure that can occur from the hemorrhage. The head should be in a midline, neutral position to facilitate venous drainage from the brain. Extreme hip and neck flexion should be avoided to prevent an increase in intrathoracic pressure and to promote venous drainage from the brain. For clients with ischemic stroke, the head of the bed usually is kept flat to ensure adequate blood flow and thus oxygenation to the brain. Prone, supine, and hip and neck flexion are incorrect positions for clients with hemorrhagic stroke.

An older client is brought to the hospital emergency department by a neighbor who heard the client talking and found him wandering in the street at 3 a.m. The nurse should first determine which data about the client? 1. His insurance status 2. Blood toxicology levels 3. Whether he ate his evening meal 4. Whether this is a change in usual level of orientation

4 The nurse should first determine whether this behavior represents a change in the client's neurological status. The next item to determine is when the client last ate. Blood toxicology levels may or may not be needed, but the health care provider would likely prescribe these. Insurance information must be obtained at some point but is not the priority from a clinical care viewpoint.

The nurse has instructed the family of a client with stroke (brain attack) who has homonymous hemianopsia about measures to help the client overcome the deficit. Which statement suggests that the family understands the measures to use when caring for the client? 1. "We need to discourage him from wearing eyeglasses." 2. "We need to place objects in his impaired field of vision." 3. "We need to approach him from the impaired field of vision." 4. "We need to remind him to turn his head to scan the lost visual field."

4 Homonymous hemianopsia is loss of half of the visual field. The client with homonymous hemianopsia should have objects placed in the intact field of vision, and the nurse also should approach the client from the intact side. The nurse instructs the client to scan the environment to overcome the visual deficit and does client teaching from within the intact field of vision. The nurse encourages the use of personal eyeglasses, if they are available.
