MSS Ch 2: Neurological Disorders Practice Questions Flashcards
(120 cards)
A 78-year-old client is admitted to the emergency department with numbness and weakness of the left arm and slurred speech. Which nursing intervention is priority? 1. Prepare to administer recombinant tissue plasminogen activator (rt-PA).
- Discuss the precipitating factors that caused the symptoms.
- Schedule for a STAT computed tomography (CT) scan of the head.
- Notify the speech pathologist for an emergency consult.
- The drug rt-PA may be administered, but a cerebrovascular accident (CVA) must be verified by diagnostic tests prior to administering it. rt-PA helps dissolve a blood clot, and it may be administered if an ischemic CVA is verified; rt-PA is not given if the client is experiencing a hemorrhagic stroke.
- Teaching is important to help prevent another CVA, but it is not the priority intervention on admission to the emergency department. Slurred speech indicates problems that may interfere with teaching.
- A CT scan will determine if the client is having a stroke or has a brain tumor or another neurological disorder. If a CVA is diagnosed, the CT scan can determine if it is a hemorrhagic or ischemic accident and guide treatment.
- The client may be referred for speech deficits and/or swallowing difficulty, but referrals are not priority in the emergency department.
The nurse is assessing a client experiencing motor loss as a result of a left-sided cere- brovascular accident (CVA). Which clinical manifestations would the nurse document? 1. Hemiparesis of the client’s left arm and apraxia.
- Paralysis of the right side of the body and ataxia.
- Homonymous hemianopsia and diplopia.
- Impulsive behavior and hostility toward family.
- A left-sided CVA will result in right-sided motor deficits; hemiparesis is weakness of one half of the body, not just the upper extremity. Apraxia, the inability to perform a previously learned task, is a communica- tion loss, not a motor loss.
- The most common motor dysfunction of a CVA is paralysis of one side of the body, hemiplegia; in this case with a left-sided CVA, the paralysis would affect the right side. Ataxia is an impaired ability to coordinate movement.
- Homonymous hemianopsia (loss of half of the visual field of each eye) and diplopia (double vision) are visual field deficits that a client with a CVA may experience, but they are not motor losses.
- Personality disorders occur in clients with a right-sided CVA and are cognitive deficits; hostility is an emotional deficit.
Which client would the nurse identify as being most at risk for experiencing a CVA?
- A 55-year-old African American male.
- An 84-year-old Japanese female.
- A 67-year-old Caucasian male.
- A 39-year-old pregnant female.
- African Americans have twice the rate of CVAs as Caucasians and men have a higher incidence than women; African Americans suffer more extensive damage from a CVA than do people of other cul- tural groups.
- Females are less likely to have a CVA than males, but advanced age does increase the risk for CVA. The Oriental population has a lower risk, possibly as a result of their relatively high intake of omega-3 fatty acids, antioxidants found in fish.
- Caucasians have a lower risk of CVA than do African Americans, Hispanics, and Native Pacific Islanders.
- Pregnancy is a minimal risk for having a CVA.
The client diagnosed with a right-sided cerebrovascular accident is admitted to the rehabilitation unit. Which interventions should be included in the nursing care plan? Select all that apply.
- Position the client to prevent shoulder adduction.
- Turn and reposition the client every shift.
- Encourage the client to move the affected side.
- Perform quadriceps exercises three (3) times a day. 5. Instruct the client to hold the fingers in a fist.
- Placing a small pillow under the shoulder will prevent the shoulder from adducting toward the chest and developing a contracture.
- The client should be repositioned at least every two (2) hours to prevent contractures, pneumonia, skin breakdown, and other complications of immobility.
- The client should not ignore the paralyzed side, and the nurse must encourage the client to move it as much as possible; a written schedule may assist the client in exercising.
- These exercises are recommended, but they must be done at least five (5) times a day for 10 minutes to help strengthen the muscles for walking.
- The fingers are positioned so that they are barely flexed to help prevent contracture of the hand.
The nurse is planning care for a client experiencing agnosia secondary to a cerebrovas- cular accident. Which collaborative intervention will be included in the plan of care?
- Observe the client swallowing for possible aspiration.
- Position the client in a semi-Fowler’s position when sleeping.
- Place a suction setup at the client’s bedside during meals.
- Refer the client to an occupational therapist for evaluation.
- Agnosia is the failure to recognize familiar objects; therefore, observing the client for possible aspiration is not appropriate.
- A semi-Fowler’s position is appropriate for sleeping, but agnosia is the failure to recognize familiar objects; therefore, this intervention is inappropriate.
- Placing suction at the bedside will help if the client has dysphagia (difficulty swallowing), not agnosia, which is failure to recognize familiar objects.
- A collaborative intervention is an intervention in which another health-care discipline—in this case, occupational therapy—is used in the care of the client.
The nurse and an unlicensed assistive personnel (UAP) are caring for a client with right-sided paralysis. Which action by the UAP requires the nurse to intervene?
- The assistant places a gait belt around the client’s waist prior to ambulating.
- The assistant places the client on the back with the client’s head to the side.
- The assistant places a hand under the client’s right axilla to move up in bed.
- The assistant praises the client for attempting to perform ADLs independently.
- Placing a gait belt prior to ambulating is an appropriate action for safety and would not require the nurse to intervene.
- Placing the client in a supine position with the head turned to the side is not a problem position, so the nurse does not need to intervene.
- This action is inappropriate and would require intervention by the nurse because pulling on a flaccid shoulder joint could cause shoulder dislocation; the client should be pulled up by placing the arm underneath the back or using a lift sheet.
- The client should be encouraged and praised for attempting to perform any activities independently, such as combing hair or brushing teeth.
The client diagnosed with atrial fibrillation has experienced a transient ischemic attack (TIA). Which medication would the nurse anticipate being ordered for the client on discharge?
- An oral anticoagulant medication.
- A beta blocker medication.
- An anti-hyperuricemic medication.
- A thrombolytic medication.
- The nurse would anticipate an oral anticoagulant, warfarin (Coumadin), to be prescribed to help prevent thrombi formation in the atria secondary to atrial fibrillation. The thrombi can become embolic and may cause a TIA or CVA (stroke).
- Beta blockers slow the heart rate and decrease blood pressure but would not be an anticipated medication to help prevent a TIA secondary to atrial fibrillation.
- An anti-hyperuricemic medication is administered for a client experiencing gout and decreases the formation of tophi.
- A thrombolytic medication is administered to dissolve a clot, and it may be ordered during the initial presentation for a client with a CVA, but not on discharge.
The client has been diagnosed with a cerebrovascular accident (stroke). The client’s wife is concerned about her husband’s generalized weakness. Which home modification should the nurse suggest to the wife prior to discharge?
- Obtain a rubber mat to place under the dinner plate.
- Purchase a long-handled bath sponge for showering.
- Purchase clothes with Velcro closure devices.
- Obtain a raised toilet seat for the client’s bathroom.
- The rubber mat will stabilize the plate and prevent it from slipping away from the client learning to feed himself, but this does not address generalized weakness.
- A long-handled bath sponge will assist
- the client when showering hard-to-reach areas, but it is not a home modification, nor will it help with generalized weakness. Clothes with Velcro closures will make dressing easier, but they do not constitute a home modification and do not address gen- eralized weakness.
- Raising the toilet seat is modifying the home and addresses the client’s weakness in being able to sit down and get up without straining muscles or requiring lifting assistance from the wife.
The client is diagnosed with expressive aphasia. Which psychosocial client problem would the nurse include in the plan of care?
- Potential for injury.
- Powerlessness.
- Disturbed thought processes.
- Sexual dysfunction.
- Potential for injury is a physiological problem, not a psychosocial problem.
- Expressive aphasia means that the client cannot communicate thoughts but understands what is being communicated; this leads to frustration, anger, depression, and the inability to verbalize needs, which, in turn, causes the client to have a lack of control and feel powerless.
- A disturbance in thought processes is a cognitive problem; with expressive aphasia the client’s thought processes are intact.
- Sexual dysfunction can have a psychosocial component or a physical component, but it is not related to expressive aphasia.
Which assessment data would indicate to the nurse that the client would be at risk for a hemorrhagic stroke?
- A blood glucose level of 480 mg/dL.
- A right-sided carotid bruit.
- A blood pressure of 220/120 mm Hg.
- The presence of bronchogenic carcinoma.
- This glucose level is elevated and could predispose the client to ischemic neurologi- cal changes due to blood viscosity, but it is not a risk factor for a hemorrhagic stroke.
- A carotid bruit predisposes the client to an embolic or ischemic stroke but not to a hemorrhagic stroke.
- Uncontrolled hypertension is a risk factor for hemorrhagic stroke, which is a ruptured blood vessel inside the cranium.
- Cancer is not a precursor to developing a hemorrhagic stroke.
The 85-year-old client diagnosed with a stroke is complaining of a severe headache. Which intervention should the nurse implement first?
- Administer a nonnarcotic analgesic.
- Prepare for STAT magnetic resonance imaging (MRI).
- Start an intravenous infusion with D5W at 100 mL/hr.
- Complete a neurological assessment.
- The nurse should not administer any medication to a client without first assessing the cause of the client’s complaint or problem.
- An MRI scan may be needed, but the nurse must determine the client’s neurological status prior to diagnostic tests.
- Starting an IV infusion is appropriate, but it is not the action the nurse should implement when assessing pain, and 100 mL/hr might be too high a rate for an 85-year-old client.
- The nurse must complete a neurological assessment to help determine the cause of the headache before taking any further action.
A client diagnosed with a subarachnoid hemorrhage has undergone a craniotomy for repair of a ruptured aneurysm. Which intervention will the intensive care nurse implement?
- Administer a stool softener b.i.d.
- Encourage the client to cough hourly.
- Monitor neurological status every shift.
- Maintain the dopamine drip to keep BP at 160/90.
- The client is at risk for increased intracranial pressure whenever performing the Valsalva maneuver, which will occur when straining during defecation. Therefore, stool softeners would be appropriate.
- Coughing increases intracranial pressure and is discouraged for any client who has had a craniotomy. The client is encour- aged to turn and breathe deeply, but not to cough.
- Monitoring the neurological status is appropriate for this client, but it should be done much more frequently than every shift.
- Dopamine is used to increase blood pres- sure or to maintain renal perfusion, and a BP of 160/90 is too high for this client.
The client diagnosed with a mild concussion is being discharged from the emergency department. Which discharge instruction should the nurse teach the client’s significant other?
- Awaken the client every two (2) hours.
- Monitor for increased intracranial pressure.
- Observe frequently for hypervigilance.
- Offer the client food every three (3) to four (4) hours.
- Awakening the client every two (2) hours allows the identification of headache, dizziness, lethargy, irritability, and anxiety—all signs of postconcussion syndrome—that would warrant the significant other’s taking the client back to the emergency department.
- The nurse should monitor for signs of increased intracranial pressure (ICP), but a layman, the significant other, would not know what these signs and medical terms mean.
- Hypervigilance, increased alertness and super-awareness of the surroundings, is a sign of amphetamine or cocaine abuse, but it would not be expected in a client with a head injury.
- The client can eat food as tolerated, but feeding the client every three (3) to four (4) hours does not affect the development of postconcussion syndrome, the signs of which are what should be taught to the significant other.
The resident in a long-term care facility fell during the previous shift and has a lacer- ation in the occipital area that has been closed with Steri-Strips. Which signs/ symptoms would warrant transferring the resident to the emergency department?
- A 4-cm area of bright red drainage on the dressing.
- A weak pulse, shallow respirations, and cool pale skin.
- Pupils that are equal, react to light, and accommodate. 4. Complaints of a headache that resolves with medication.
- The scalp is a very vascular area and a moderate amount of bleeding would be expected.
- These signs/symptoms—weak pulse, shallow respirations, cool pale skin— indicate increased intracranial pressure from cerebral edema secondary to the fall, and they require immediate attention.
- This is a normal pupillary response and would not warrant intervention.
- A headache that resolves with medication is not an emergency situation, and the nurse would expect the client to have a headache after the fall; a headache not relieved with Tylenol would warrant further investigation.
The nurse is caring for the following clients. Which client would the nurse assess first after receiving the shift report?
1. The 22-year-old male client diagnosed with a concussion who is complaining
someone is waking him up every two (2) hours.
2. The 36-year-old female client admitted with complaints of left-sided weakness
who is scheduled for a magnetic resonance imaging (MRI) scan.
3. The 45-year-old client admitted with blunt trauma to the head after a motorcycle
accident who has a Glasgow Coma Scale score of 6.
4. The 62-year-old client diagnosed with a cerebrovascular accident (CVA) who has
expressive aphasia.
- A client with a head injury must be awakened every two (2) hours to determine alertness; decreasing level of consciousness is the first indicator of increased intracranial pressure.
- A diagnostic test, MRI, would be an expected test for a client with left-sided weakness and would not require immediate attention.
- The Glasgow Coma Scale is used to determine a client’s response to stimuli (eye-opening response, best verbal response, and best motor response) secondary to a neurological problem; scores range from 3 (deep coma) to 15 (intact neurological function). A client with a score of 6 should be assessed first by the nurse.
- The nurse would expect a client diagnosed with a CVA (stroke) to have some sequelae of the problem, including the inability to speak.
The client has sustained a severe closed head injury and the neurosurgeon is deter- mining if the client is “brain dead.” Which data support that the client is brain dead?
- When the client’s head is turned to the right, the eyes turn to the right.
- The electroencephalogram (EEG) has identifiable waveforms.
- There is no eye activity when the cold caloric test is performed.
- The client assumes decorticate posturing when painful stimuli are applied.
- This is an oculocephalic test (doll’s eye movement) that determines brain activity. If the eyes move with the head, it means the brainstem is intact and there is no brain death.
- Waveforms on the EEG indicate that there is brain activity.
- The cold caloric test, also called the oculovestibular test, is a test used to determine if the brain is intact or dead. No eye activity indicates brain death. If the client’s eyes moved, that would indicate that the brainstem is intact.
- Decorticate posturing after painful stimuli are applied indicates that the brainstem is intact; flaccid paralysis is the worse neuro- logical response when assessing a client with a head injury.
The client is admitted to the medical floor with a diagnosis of closed head injury. Which nursing intervention has priority?
- Assess neurological status.
- Monitor pulse, respiration, and blood pressure.
- Initiate an intravenous access.
- Maintain an adequate airway.
- Assessing the neurological status is important, but ensuring an airway is priority over assessment.
- Monitoring vital signs is important, but maintaining an adequate airway is higher priority.
- Initiating an IV access is an intervention the nurse can implement, but it is not the priority intervention.
- The most important nursing goal in the management of a client with a head injury is to establish and maintain an adequate airway.
The client diagnosed with a closed head injury is admitted to the rehabilitation department. Which medication order would the nurse question?
- A subcutaneous anticoagulant.
- An intravenous osmotic diuretic.
- An oral anticonvulsant.
- An oral proton pump inhibitor.
- The client in rehabilitation is at risk for the development of deep vein thrombosis; therefore, this is an appropriate medication.
- An osmotic diuretic would be ordered in the acute phase to help decrease cerebral edema, but this medication would not be expected to be ordered in a rehabilitation unit.
- Clients with head injuries are at risk for post-traumatic seizures; thus an oral anticonvulsant would be administered for seizure prophylaxis.
- The client is at risk for a stress ulcer; therefore, an oral proton pump inhibitor would be an appropriate medication.
The client diagnosed with a gunshot wound to the head assumes decorticate posturing when the nurse applies painful stimuli. Which assessment data obtained three (3) hours later would indicate the client is improving?
- Purposeless movement in response to painful stimuli.
- Flaccid paralysis in all four extremities.
- Decerebrate posturing when painful stimuli are applied.
- Pupils that are 6 mm in size and nonreactive on painful stimuli.
- Purposeless movement indicates that the client’s cerebral edema is decreasing. The best motor response is purposeful movement, but purposeless movement indicates an improvement over decorticate movement, which, in turn, is an improvement over decerebrate movement or flaccidity.
- Flaccidity would indicate a worsening of the client’s condition.
- Decerebrate posturing would indicate a worsening of the client’s condition.
- The eyes respond to light, not painful stimuli, but a 6-mm nonreactive pupil indicates severe neurological deficit.
The nurse is caring for a client diagnosed with an epidural hematoma. Which nursing interventions should the nurse implement? Select all that apply.
- Maintain the head of the bed at 60 degrees of elevation.
- Administer stool softeners daily.
- Ensure that pulse oximeter reading is higher than 93%. 4. Perform deep nasal suction every two (2) hours.
- Administer mild sedatives.
- The head of the bed should be elevated no more than 30 degrees to help decrease cerebral edema by gravity.
- Stool softeners are initiated to prevent the Valsalva maneuver, which increases intracranial pressure.
- Oxygen saturation higher than 93% ensures oxygenation of the brain tissues; decreasing oxygen levels increase cerebral edema.
- Noxious stimuli, such as suctioning, increase intracranial pressure and should be avoided.
- Mild sedatives will reduce the client’s agitation; strong narcotics would not be administered because they decrease the client’s level of consciousness.
The client with a closed head injury has clear fluid draining from the nose. Which action should the nurse implement first?
- Notify the health-care provider immediately.
- Prepare to administer an antihistamine.
- Test the drainage for presence of glucose.
- Place 2 × 2 gauze under the nose to collect drainage.
- Prior to notifying the HCP, the nurse should always make sure that all the needed assessment information is available to discuss with the HCP.
- With head injuries, any clear drainage may indicate a cerebrospinal fluid leak; the nurse should not assume the drainage is secondary to allergies and administer an antihistamine.
- The presence of glucose in drainage from the nose or ears indicates cerebrospinal fluid, and the HCP should be notified immediately once this is determined.
- This would be appropriate, but it is not the first intervention. The nurse must determine where the fluid is coming from.
The nurse is enjoying a day at the lake and witnesses a water skier hit the boat ramp. The water skier is in the water not responding to verbal stimuli. The nurse is the first health-care provider to respond to the accident. Which intervention should be implemented first?
- Assess the client’s level of consciousness.
- Organize onlookers to remove the client from the lake. 3. Perform a head-to-toe assessment to determine injuries.
- Stabilize the client’s cervical spine.
- Assessment is important, but with clients with head injury the nurse must assume spinal cord injury until it is ruled out with x-ray; therefore, stabilizing the spinal cord is priority.
- Removing the client from the water is an appropriate intervention, but the nurse must assume spinal cord injury until it is ruled out with x-ray; therefore, stabilizing the spinal cord is priority.
- Assessing the client for further injury is appropriate, but the first intervention is to stabilize the spine because the impact was strong enough to render the client unconsciousness.
- The nurse should always assume that a client with traumatic head injury may have sustained spinal cord injury. Mov- ing the client could further injure the spinal cord and cause paralysis; there- fore, the nurse should stabilize the cer- vical spinal cord as best as possible prior to removing the client from the water.
The client is diagnosed with a closed head injury and is in a coma. The nurse writes the client problem as “high risk for immobility complications.” Which intervention would be included in the plan of care?
- Position the client with the head of the bed elevated at intervals.
- Perform active range-of-motion exercises every four (4) hours.
- Turn the client every shift and massage bony prominences.
- Explain all procedures to the client before performing them.
- The head of the client’s bed should be elevated to help the lungs expand and prevent stasis of secretions that could lead to pneumonia, a complication of immobility.
- Active range-of-motion exercises require that the client participate in the activity. This is not possible because the client is in a coma.
- The client is at risk for pressure ulcers and should be turned more frequently than every shift, and research now shows that massaging bony prominences can increase the risk for tissue breakdown.
- The nurse should always talk to the client, even if he or she is in a coma, but this will not address the problem of immobility.
The 29-year-old client who was employed as a forklift operator sustains a traumatic brain injury secondary to a motor-vehicle accident. The client is being discharged from the rehabilitation unit after three (3) months and has cognitive deficits. Which goal would be most realistic for this client?
- The client will return to work within six (6) months.
- The client is able to focus and stay on task for 10 minutes.
- The client will be able to dress self without assistance.
- The client will regain bowel and bladder control.
- The client is at risk for seizures and does not process information appropriately. Allowing him to return to his occupation as a forklift operator is a safety risk for him and other employees. Vocational training may be required.
- “Cognitive” pertains to mental processes of comprehension, judgment, memory, and reasoning. Therefore, an appropriate goal would be for the client to stay on task for 10 minutes.
- The client’s ability to dress self addresses self-care problems, not a cognitive problem.
- The client’s ability to regain bowel and bladder control does not address cognitive deficits.
