question

The nurse expects that management of the patient who experiences a brief episode of tinnitus, diplopia, and dysarthria with no residual effects will include a. prophylactic clipping of cerebral aneurysms. b. heparin via continuous intravenous infusion. c. oral administration of low dose aspirin therapy. d. therapy with tissue plasminogen activator (tPA).

answer

ANS: C The patient's symptoms are consistent with transient ischemic attack (TIA), and drugs that inhibit platelet aggregation are prescribed after a TIA to prevent stroke. Continuous heparin infusion is not routinely used after TIA or with acute ischemic stroke. The patient's symptoms are not consistent with a cerebral aneurysm. tPA is used only for acute ischemic stroke, not for TIA.

question

Aspirin is ordered for a patient who is admitted with a possible stroke. Which information obtained during the admission assessment indicates that the nurse should consult with the health care provider before giving the aspirin? a. The patient has dysphasia. b. The patient has atrial fibrillation. c. The patient states, "My symptoms started with a terrible headache." d. The patient has a history of brief episodes of right-sided hemiplegia.

answer

ANS: C A sudden onset headache is typical of a subarachnoid hemorrhage, and aspirin is contraindicated. Atrial fibrillation, dysphasia, and transient ischemic attack (TIA) are not contraindications to aspirin use, so the nurse can administer the aspirin.

question

A patient with a stroke experiences right-sided arm and leg paralysis and facial drooping on the right side. When admitting the patient, which clinical manifestation will the nurse expect to find? a. Impulsive behavior b. Right-sided neglect c. Hyperactive left-sided reflexes d. Difficulty in understanding commands

answer

ANS: D Right-sided paralysis indicates a left-brain stroke, which will lead to difficulty with comprehension and use of language. The left-side reflexes are likely to be intact. Impulsive behavior and neglect are more likely with a right-side stroke.

question

The nurse receives a verbal report that a patient has an occlusion of the left posterior cerebral artery. The nurse will anticipate that the patient may have a. dysphasia. b. confusion. c. visual deficits. d. poor judgment.

answer

ANS: C Visual disturbances are expected with posterior cerebral artery occlusion. Aphasia occurs with middle cerebral artery involvement. Cognitive deficits and changes in judgment are more typical of anterior cerebral artery occlusion.

question

The health care provider prescribes clopidogrel (Plavix) for a patient with cerebral atherosclerosis. When teaching about the new medication, the nurse will tell the patient a. to monitor and record the blood pressure daily. b. to call the health care provider if stools are tarry. c. that Plavix will dissolve clots in the cerebral arteries. d. that Plavix will reduce cerebral artery plaque formation.

answer

ANS: B Plavix inhibits platelet function and increases the risk for gastrointestinal bleeding, so patients should be advised to notify the health care provider about any signs of bleeding. The medication does not lower blood pressure, decrease plaque formation, or dissolve clots.

question

The health care provider recommends a carotid endarterectomy for a patient with carotid atherosclerosis and a history of transient ischemic attacks (TIAs). The patient asks the nurse to describe the procedure. Which response by the nurse is appropriate? a. "The carotid endarterectomy involves surgical removal of plaque from an artery in the neck." b. "The diseased portion of the artery in the brain is removed and replaced with a synthetic graft." c. "A wire is threaded through an artery in the leg to the clots in the carotid artery and the clots are removed." d. "A catheter with a deflated balloon is positioned at the narrow area, and the balloon is inflated to flatten the plaque."

answer

ANS: A In a carotid endarterectomy, the carotid artery is incised and the plaque is removed. The response beginning, "The diseased portion of the artery in the brain is removed" describes an arterial graft procedure. The answer beginning, "A catheter with a deflated balloon is positioned at the narrow area" describes an angioplasty. The final response beginning, "A wire is threaded through the artery" describes the MERCI procedure.

question

When assessing a patient with a possible stroke, the nurse finds that the patient's aphasia started 3.5 hours previously and the blood pressure is 170/92 mm Hg. Which of these orders by the health care provider should the nurse question? a. Infuse normal saline at 75 mL/hr. b. Keep head of bed elevated at least 30 degrees. c. Administer tissue plasminogen activator (tPA) per protocol. d. Titrate labetalol (Normodyne) drip to keep BP less than 140/90 mm Hg.

answer

ANS: D Because elevated BP may be a protective response to maintain cerebral perfusion, antihypertensive therapy is recommended only if mean arterial pressure (MAP) is >130 mm Hg or systolic pressure is >220 mm Hg. Fluid intake should be 1500 to 2000 mL daily to maintain cerebral blood flow. The head of the bed should be elevated to at least 30 degrees, unless the patient has symptoms of poor tissue perfusion. tPA may be administered if the patient meets the other criteria for tPA use.

question

A patient with a history of several transient ischemic attacks (TIAs) arrives in the emergency department with hemiparesis and dysarthria that started 2 hours previously. The nurse anticipates the need to prepare the patient for a. surgical endarterectomy. b. transluminal angioplasty. c. intravenous heparin administration. d. tissue plasminogen activator (tPA) infusion.

answer

ANS: D The patient's history and clinical manifestations suggest an acute ischemic stroke and a patient who is seen within 4.5 hours of stroke onset is likely to receive tPA (after screening with a CT scan). Heparin administration in the emergency phase is not indicated. Emergent carotid transluminal angioplasty or endarterectomy is not indicated for the patient who is having an acute ischemic stroke.

question

The nurse identifies the nursing diagnosis of impaired verbal communication for a patient with expressive aphasia. An appropriate nursing intervention to help the patient communicate is to a. have the patient practice facial and tongue exercises. b. ask simple questions that the patient can answer with "yes" or "no." c. develop a list of words that the patient can read and practice reciting. d. prevent embarrassing the patient by changing the subject if the patient does not respond.

answer

ANS: B Communication will be facilitated and less frustrating to the patient when questions that require a "yes" or "no" response are used. When the language areas of the brain are injured, the patient might not be able to read or recite words, which will frustrate the patient without improving communication. Expressive aphasia is caused by damage to the language areas of the brain, not by the areas that control the motor aspects of speech. The nurse should allow time for the patient to respond.

question

A patient has a stroke affecting the right hemisphere of the brain. Based on knowledge of the effects of right brain damage, the nurse establishes a nursing diagnosis of a. impaired physical mobility related to right hemiplegia. b. risk for injury related to denial of deficits and impulsiveness. c. impaired verbal communication related to speech-language deficits. d. ineffective coping related to depression and distress about disability.

answer

ANS: B Right-sided brain damage typically causes denial of any deficits and poor impulse control, leading to risk for injury when the patient attempts activities such as transferring from a bed to a chair. Right-sided brain damage causes left hemiplegia. Left-sided brain damage typically causes language deficits. Left-sided brain damage is associated with depression and distress about the disability.

question

When caring for a patient with left-sided homonymous hemianopsia resulting from a stroke, which intervention should the nurse include in the plan of care during the acute period of the stroke? a. Apply an eye patch to the left eye. b. Approach the patient from the left side. c. Place objects needed for activities of daily living on the patient's right side. d. Reassure the patient that the visual deficit will resolve as the stroke progresses.

answer

ANS: C During the acute period, the nurse should place objects on the patient's unaffected side. Since there is a visual defect in the left half of each eye, an eye patch is not appropriate. The patient should be approached from the right side. The visual deficit may not resolve, although the patient can learn to compensate for the defect.

question

The nurse identifies the nursing diagnosis of imbalanced nutrition: less than body requirements related to impaired self-feeding ability for a patient with right-sided hemiplegia. Which intervention should be included in the plan of care? a. Provide a wide variety of food choices. b. Provide oral care before and after meals. c. Assist the patient to eat with the left hand. d. Teach the patient the "chin-tuck" technique.

answer

ANS: C Because the nursing diagnosis indicates that the patient's imbalanced nutrition is related to the right-sided hemiplegia, the appropriate interventions will focus on teaching the patient to use the left hand for self-feeding. The other interventions are appropriate for patients with other etiologies for the imbalanced nutrition.

question

A 32-year-old patient has a stroke resulting from a ruptured aneurysm and subarachnoid hemorrhage. Which intervention will be included in the care plan? a. Applying intermittent pneumatic compression stockings b. Assisting to dangle on edge of bed and assess for dizziness c. Encouraging patient to cough and deep breathe every 4 hours d. Inserting an oropharyngeal airway to prevent airway obstruction

answer

ANS: A The patient with a subarachnoid hemorrhage usually has minimal activity to prevent cerebral vasospasm or further bleeding and is at risk for venous thromboemboism (VTE). Activities such as coughing and sitting up that might increase intracranial pressure (ICP) or decrease cerebral blood flow are avoided. Because there is no indication that the patient is unconscious, an oropharyngeal airway is inappropriate.

question

A patient who has had a stroke has a new order to attempt oral feedings. The nurse should assess the gag reflex and then a. order a varied pureed diet. b. assess the patient's appetite. c. assist the patient into a chair. d. offer the patient a sip of juice.

answer

ANS: C The patient should be as upright as possible before attempting feeding to make swallowing easier and decrease aspiration risk. To assess swallowing ability, the nurse should initially offer water or ice to the patient. Pureed diets are not recommended because the texture is too smooth. The patient may have a poor appetite, but the oral feeding should be attempted regardless.

question

A patient who has right-sided weakness after a stroke is attempting to use the left hand for feeding and other activities. The patient's wife insists on feeding and dressing him, telling the nurse, "I just don't like to see him struggle." Which nursing diagnosis is most appropriate for the patient? a. Situational low self-esteem related to increasing dependence on others b. Interrupted family processes related to effects of illness of a family member c. Disabled family coping related to inadequate understanding by patient's spouse d. Impaired nutrition: less than body requirements related to hemiplegia and aphasia

answer

ANS: C The information supports the diagnosis of disabled family coping because the wife does not understand the rehabilitation program. There are no data supporting low self-esteem, and the patient is attempting independence. The data do not support an interruption in family processes because this may be a typical pattern for the couple. There is no indication that the patient has impaired nutrition.

question

Several weeks after a stroke, a patient has urinary incontinence resulting from an impaired awareness of bladder fullness. For an effective bladder training program, which nursing intervention will be best to include in the plan of care? a. Limit fluid intake to 1200 mL daily to reduce urine volume. b. Assist the patient onto the bedside commode every 2 hours. c. Perform intermittent catheterization after each voiding to check for residual urine. d. Use an external "condom" catheter to protect the skin and prevent embarrassment.

answer

ANS: B Developing a regular voiding schedule will prevent incontinence and may increase patient awareness of a full bladder. A 1200 mL fluid restriction may lead to dehydration. Intermittent catheterization and use of a condom catheter are appropriate in the acute phase of stroke but should not be considered solutions for long-term management because of the risks for urinary tract infection (UTI) and skin breakdown.

question

A patient who has a history of a transient ischemic attack (TIA) has an order for aspirin 160 mg daily. When the nurse is administering the medications, the patient says, "I don't need the aspirin today. I don't have any aches or pains." Which action should the nurse take? a. Document that the aspirin was refused by the patient. b. Tell the patient that the aspirin is used to prevent aches. c. Explain that the aspirin is ordered to decrease stroke risk. d. Call the health care provider to clarify the medication order.

answer

ANS: C Aspirin is ordered to prevent stroke in patients who have experienced TIAs. Documentation of the patient's refusal to take the medication is an inadequate response by the nurse. There is no need to clarify the order with the health care provider. The aspirin is not ordered to prevent aches and pains.

question

A patient is admitted to the hospital with dysphasia and right-sided weakness that resolves in a few hours. The nurse will anticipate teaching the patient about a. alteplase (tPA). b. aspirin (Ecotrin). c. warfarin (Coumadin). d. nimodipine (Nimotop).

answer

ANS: B Following a TIA, patients typically are started on medications such as aspirin to inhibit platelet function and decrease stroke risk. tPA is used for acute ischemic stroke. Coumadin is usually used for patients with atrial fibrillation. Nimodipine is used to prevent cerebral vasospasm after a subarachnoid hemorrhage.

question

A patient with a left-sided brain stroke suddenly bursts into tears when family members visit. The nurse should a. use a calm voice to ask the patient to stop the crying behavior. b. explain to the family that depression is normal following a stroke. c. have the family members leave the patient alone for a few minutes. d. teach the family that emotional outbursts are common after strokes.

answer

ANS: D Patients who have left-sided brain stroke are prone to emotional outbursts, which are not necessarily related to the emotional state of the patient. Depression after a stroke is common, but the suddenness of the patient's outburst suggests that depression is not the major cause of the behavior. The family should stay with the patient. The crying is not within the patient's control and asking the patient to stop will lead to embarrassment.

question

The nurse obtains all of the following information about a 65-year-old patient in the clinic. When developing a plan to decrease stroke risk, which risk factor is most important for the nurse to address? a. The patient has a daily glass of wine to relax. b. The patient is 25 pounds above the ideal weight. c. The patient works at a desk and relaxes by watching television. d. The patient's blood pressure (BP) is usually about 180/90 mm Hg.

answer

ANS: D Hypertension is the single most important modifiable risk factor and this patient's hypertension is at the stage 2 level. People who drink more than 1 (for women) or 2 (for men) alcoholic beverages a day may increase risk for hypertension. Physical inactivity and obesity contribute to stroke risk but not so much as hypertension.

question

A patient with sudden-onset right-sided weakness has a CT scan and is diagnosed with an intracerebral hemorrhage. Which information about the patient is most important to communicate to the health care provider? a. The patient's speech is difficult to understand. b. The patient's blood pressure is 144/90 mm Hg. c. The patient takes a diuretic because of a history of hypertension. d. The patient has atrial fibrillation and takes warfarin (Coumadin).

answer

ANS: D The use of warfarin will have contributed to the intracerebral bleeding and remains a risk factor for further bleeding. Administration of vitamin K is needed to reverse the effects of the warfarin, especially if the patient is to have surgery to correct the bleeding. The history of hypertension is a risk factor for the patient but has no immediate effect on the patient's care. The BP of 144/90 indicates the need for ongoing monitoring but not for any immediate change in therapy. Slurred speech is consistent with a left-sided stroke, and no change in therapy is indicated.

question

A patient with right-sided weakness that started 90 minutes earlier is admitted to the emergency department and all these diagnostic tests are ordered. Which test should be done first? a. Electrocardiogram (ECG) b. Complete blood count (CBC) c. Chest radiograph (Chest x-ray) d. Noncontrast computed tomography (CT) scan

answer

ANS: D Rapid screening with a noncontrast CT scan is needed before administration of tissue plasminogen activator (tPA), which must be given within 4.5 hours of the onset of clinical manifestations of the stroke. The sooner the tPA is given, the smaller the area of brain injury. The other diagnostic tests give information about possible causes of the stroke and do not need to be completed as urgently as the CT scan.

question

A patient with a stroke has progressive development of neurologic deficits with increasing weakness and decreased level of consciousness (LOC). Which nursing diagnosis has the highest priority for the patient? a. Impaired physical mobility related to weakness b. Disturbed sensory perception related to brain injury c. Risk for impaired skin integrity related to immobility d. Risk for aspiration related to inability to protect airway

answer

ANS: D Protection of the airway is the priority of nursing care for a patient having an acute stroke. The other diagnoses also are appropriate, but interventions to prevent aspiration are the priority at this time.

question

A patient who has had a subarachnoid hemorrhage is being cared for in the intensive care unit. Which information about the patient is most important to communicate to the health care provider? a. The patient's blood pressure is 90/50 mm Hg. b. The patient complains about having a stiff neck. c. The cerebrospinal fluid (CSF) report shows red blood cells (RBCs). d. The patient complains of an ongoing severe headache.

answer

ANS: A To prevent cerebral vasospasm and maintain cerebral perfusion, blood pressure needs to be maintained at a level higher than 90 mm Hg systolic after a subarachnoid hemorrhage. A low BP or drop in BP indicates a need to administer fluids and/or vasopressors to increase the BP. An ongoing headache, RBCs in the CSF, and a stiff neck are all typical clinical manifestations of a subarachnoid hemorrhage and do not need to be rapidly communicated to the health care provider.

question

Which of these nursing actions included in the care of a patient who has been experiencing stroke symptoms for 60 minutes can the nurse delegate to an LPN/LVN? a. Assess the patient's gag and cough reflexes. b. Determine when the stroke symptoms began. c. Administer the prescribed clopidogrel (Plavix). d. Infuse the prescribed IV metoprolol (Lopressor).

answer

ANS: C Administration of oral medications is included in LPN education and scope of practice. The other actions require more education and scope of practice and should be done by the RN.

question

After receiving change-of-shift report on the following four patients, which patient should the nurse see first? a. A patient with right-sided weakness who has an infusion of tPA prescribed b. A patient who has atrial fibrillation and a new order for warfarin (Coumadin) c. A patient who experienced a transient ischemic attack yesterday who has a dose of aspirin due d. A patient with a subarachnoid hemorrhage 2 days ago who has nimodipine (Nimotop) scheduled

answer

ANS: A tPA needs to be infused within the first few hours after stroke symptoms start in order to be effective in minimizing brain injury. The other medications also should be given as quickly as possible, but timing of the medications is not as critical.

question

The nurse is caring for a patient with carotid artery narrowing who has just returned after having left carotid artery angioplasty and stenting. Which assessment information is of most concern to the nurse? a. The pulse rate is 104 beats/min. b. The patient has difficulty talking. c. The blood pressure is 142/88 mm Hg. d. There are fine crackles at the lung bases.

answer

ANS: B Small emboli can occur during carotid artery angioplasty and stenting, and the aphasia indicates a possible stroke during the procedure. Slightly elevated pulse rate and blood pressure are not unusual because of anxiety associated with the procedure. Fine crackles at the lung bases may indicate atelectasis caused by immobility during the procedure; the nurse should have the patient take some deep breaths.

question

A patient with left-sided hemiparesis arrives by ambulance to the emergency department. Which action should the nurse take first? a. Check the respiratory rate. b. Monitor the blood pressure. c. Send the patient for a CT scan. d. Obtain the Glasgow Coma Scale score.

answer

ANS: A The initial nursing action should be to assess the airway and take any needed actions to ensure a patent airway. The other activities should take place quickly after the ABCs (airway, breathing, circulation) are completed.

question

A 58-year-old patient who began experiencing right-sided arm and leg weakness is admitted to the emergency department. In which order will the nurse implement these actions included in the stroke protocol? Put a comma and space between each answer choice (a, b, c, d, etc.) ____________________ a. Obtain CT scan without contrast. b. Infuse tissue plasminogen activator (tPA). c. Administer oxygen to keep O2 saturation >95%. d. Use National Institute of Health Stroke Scale to assess patient

answer

ANS: C, D, A, B The initial actions should be those that help with airway, breathing, and circulation. Baseline neurologic assessments should be done next. A CT scan will be needed to rule out hemorrhagic stroke before tPA can be administered.

question

After a patient experienced a brief episode of tinnitus, diplopia, and dysarthria with no residual effects, the nurse anticipates teaching the patient about a. cerebral aneurysm clipping. b. heparin intravenous infusion. c. oral low-dose aspirin therapy. d. tissue plasminogen activator (tPA).

answer

ANS: C The patient's symptoms are consistent with transient ischemic attack (TIA), and drugs that inhibit platelet aggregation are prescribed after a TIA to prevent stroke. Continuous heparin infusion is not routinely used after TIA or with acute ischemic stroke. The patient's symptoms are not consistent with a cerebral aneurysm. tPA is used only for acute ischemic stroke, not for TIA.

question

A 68-year-old patient is being admitted with a possible stroke. Which information from the assessment indicates that the nurse should consult with the health care provider before giving the prescribed aspirin? a. The patient has dysphasia. b. The patient has atrial fibrillation. c. The patient reports that symptoms began with a severe headache. d. The patient has a history of brief episodes of right-sided hemiplegia.

answer

ANS: C A sudden onset headache is typical of a subarachnoid hemorrhage, and aspirin is contraindicated. Atrial fibrillation, dysphasia, and transient ischemic attack (TIA) are not contraindications to aspirin use, so the nurse can administer the aspirin.

question

A 73-year-old patient with a stroke experiences facial drooping on the right side and right-sided arm and leg paralysis. When admitting the patient, which clinical manifestation will the nurse expect to find? a. Impulsive behavior b. Right-sided neglect c. Hyperactive left-sided tendon reflexes d. Difficulty comprehending instructions

answer

ANS: D Right-sided paralysis indicates a left-brain stroke, which will lead to difficulty with comprehension and use of language. The left-side reflexes are likely to be intact.

question

A male patient who has right-sided weakness after a stroke is making progress in learning to use the left hand for feeding and other activities. The nurse observes that when the patient's wife is visiting, she feeds and dresses him. Which nursing diagnosis is most appropriate for the patient? a. Interrupted family processes related to effects of illness of a family member b. Situational low self-esteem related to increasing dependence on spouse for care c. Disabled family coping related to inadequate understanding by patient's spouse d. Impaired nutrition: less than body requirements related to hemiplegia and aphasia

question

Several weeks after a stroke, a 50-year-old male patient has impaired awareness of bladder fullness, resulting in urinary incontinence. Which nursing intervention will be best to include in the initial plan for an effective bladder training program? a. Limit fluid intake to 1200 mL daily to reduce urine volume. b. Assist the patient onto the bedside commode every 2 hours. c. Perform intermittent catheterization after each voiding to check for residual urine. d. Use an external "condom" catheter to protect the skin and prevent embarrassment.

answer

ANS: B Developing a regular voiding schedule will prevent incontinence and may increase patient awareness of a full bladder. A 1200 mL fluid restriction may lead to dehydration. Intermittent catheterization and use of a condom catheter are appropriate in the acute phase of stroke, but should not be considered solutions for long-term management because of the risks for urinary tract infection (UTI) and skin breakdown.

question

A 72-year-old patient who has a history of a transient ischemic attack (TIA) has an order for aspirin 160 mg daily. When the nurse is administering medications, the patient says, "I don't need the aspirin today. I don't have a fever." Which action should the nurse take? a. Document that the aspirin was refused by the patient. b. Tell the patient that the aspirin is used to prevent a fever. c. Explain that the aspirin is ordered to decrease stroke risk. d. Call the health care provider to clarify the medication order.

answer

ANS: C Aspirin is ordered to prevent stroke in patients who have experienced TIAs. Documentation of the patient's refusal to take the medication is an inadequate response by the nurse. There is no need to clarify the order with the health care provider. The aspirin is not ordered to prevent aches and pains.

question

A patient in the clinic reports a recent episode of dysphasia and left-sided weakness at home that resolved after 2 hours. The nurse will anticipate teaching the patient about a. alteplase (tPA). b. aspirin (Ecotrin). c. warfarin (Coumadin). d. nimodipine (Nimotop).

answer

ANS: B Following a transient ischemic attack (TIA), patients typically are started on medications such as aspirin to inhibit platelet function and decrease stroke risk. tPA is used for acute ischemic stroke. Coumadin is usually used for patients with atrial fibrillation. Nimodipine is used to prevent cerebral vasospasm after a subarachnoid hemorrhage.

question

A 58-year-old patient with a left-brain stroke suddenly bursts into tears when family members visit. The nurse should a. use a calm voice to ask the patient to stop the crying behavior. b. explain to the family that depression is normal following a stroke. c. have the family members leave the patient alone for a few minutes. d. teach the family that emotional outbursts are common after strokes.

answer

ANS: D Patients who have left-sided brain stroke are prone to emotional outbursts that are not necessarily related to the emotional state of the patient. Depression after a stroke is common, but the suddenness of the patient's outburst suggests that depression is not the major cause of the behavior. The family should stay with the patient. The crying is not within the patient's control and asking the patient to stop will lead to embarrassment.

question

Which stroke risk factor for a 48-year-old male patient in the clinic is most important for the nurse to address? a. The patient is 25 pounds above the ideal weight. b. The patient drinks a glass of red wine with dinner daily. c. The patient's usual blood pressure (BP) is 170/94 mm Hg. d. The patient works at a desk and relaxes by watching television.

answer

ANS: C Hypertension is the single most important modifiable risk factor. People who drink more than 1 (for women) or 2 (for men) alcoholic beverages a day may increase risk for hypertension. Physical inactivity and obesity contribute to stroke risk but not as much as hypertension.

question

A patient in the emergency department with sudden-onset right-sided weakness is diagnosed with an intracerebral hemorrhage. Which information about the patient is most important to communicate to the health care provider? a. The patient's speech is difficult to understand. b. The patient's blood pressure is 144/90 mm Hg. c. The patient takes a diuretic because of a history of hypertension. d. The patient has atrial fibrillation and takes warfarin (Coumadin).

answer

ANS: D The use of warfarin probably contributed to the intracerebral bleeding and remains a risk factor for further bleeding. Administration of vitamin K is needed to reverse the effects of the warfarin, especially if the patient is to have surgery to correct the bleeding. The history of hypertension is a risk factor for the patient but has no immediate effect on the patient's care. The BP of 144/90 indicates the need for ongoing monitoring but not for any immediate change in therapy. Slurred speech is consistent with a left-sided stroke, and no change in therapy is indicated.

question

A patient with left-sided weakness that started 60 minutes earlier is admitted to the emergency department and diagnostic tests are ordered. Which test should be done first? a. Complete blood count (CBC) b. Chest radiograph (Chest x-ray) c. 12-Lead electrocardiogram (ECG) d. Noncontrast computed tomography (CT) scan

answer

ANS: D Rapid screening with a noncontrast CT scan is needed before administration of tissue plasminogen activator (tPA), which must be given within 4.5 hours of the onset of clinical manifestations of the stroke. The sooner the tPA is given, the less brain injury. The other diagnostic tests give information about possible causes of the stroke and do not need to be completed as urgently as the CT scan.

question

Nurses in change-of-shift report are discussing the care of a patient with a stroke who has progressively increasing weakness and decreasing level of consciousness (LOC). Which nursing diagnosis do they determine has the highest priority for the patient? a. Impaired physical mobility related to weakness b. Disturbed sensory perception related to brain injury c. Risk for impaired skin integrity related to immobility d. Risk for aspiration related to inability to protect airway

answer

ANS: D Protection of the airway is the priority of nursing care for a patient having an acute stroke. The other diagnoses are also appropriate, but interventions to prevent aspiration are the priority at this time.

question

Which information about the patient who has had a subarachnoid hemorrhage is most important to communicate to the health care provider? a. The patient complains of having a stiff neck. b. The patient's blood pressure (BP) is 90/50 mm Hg. c. The patient reports a severe and unrelenting headache. d. The cerebrospinal fluid (CSF) report shows red blood cells (RBCs).

answer

ANS: B To prevent cerebral vasospasm and maintain cerebral perfusion, blood pressure needs to be maintained at a level higher than 90 mm Hg systolic after a subarachnoid hemorrhage. A low BP or drop in BP indicates a need to administer fluids and/or vasopressors to increase the BP. An ongoing headache, RBCs in the CSF, and a stiff neck are all typical clinical manifestations of a subarachnoid hemorrhage and do not need to be rapidly communicated to the health care provider.

A 40-year-old patient who experienced a transient ischemic attack yesterday who has a dose of aspirin due d. A 30-year-old patient with a subarachnoid hemorrhage 2 days ago who has nimodipine (Nimotop) scheduled

answer

ANS: A tPA needs to be infused within the first few hours after stroke symptoms start in order to be effective in minimizing brain injury.

question

The nurse is caring for a patient who has just returned after having left carotid artery angioplasty and stenting. Which assessment information is of most concern to the nurse? a. The pulse rate is 102 beats/min. b. The patient has difficulty speaking. c. The blood pressure is 144/86 mm Hg. d. There are fine crackles at the lung bases.

answer

ANS: B Small emboli can occur during carotid artery angioplasty and stenting, and the aphasia indicates a possible stroke during the procedure. Slightly elevated pulse rate and blood pressure are not unusual because of anxiety associated with the procedure. Fine crackles at the lung bases may indicate atelectasis caused by immobility during the procedure. The nurse should have the patient take some deep breaths.

question

The home health nurse is caring for an 81-year-old who had a stroke 2 months ago. Based on information shown in the accompanying figure from the history, physical assessment, and physical therapy/occupational therapy, which nursing diagnosis is the highest priority for this patient? a. Impaired transfer ability b. Risk for caregiver role strain c. Ineffective health maintenance d. Risk for unstable blood glucose level

answer

ANS: B The spouse's household and patient care responsibilities, in combination with chronic illnesses, indicate a high risk for caregiver role strain. The nurse should further assess the situation and take appropriate actions. The data about the control of the patient's diabetes indicates that ineffective health maintenance and risk for unstable blood glucose are not priority concerns at this time. Because the patient is able to ambulate with a cane, the nursing diagnosis of impaired transfer ability is not supported.

question

Bridge to NCLEX question: The factor related to cerebral blood flow that most often determines the extent of cerebral damage from a stroke is the a. amount of cardiac output. b. oxygen content of the blood. c. degree of collateral circulation. d. level of carbon dioxide in the blood.

answer

*c. degree of collateral circulation.* Rationale: The extent of the stroke depends on the rapidity of onset, size of the lesion, and presence of collateral circulation.

question

Bridge to NCLEX question: Information provided by the patient that would help differentiate a hemorrhagic stroke from a thrombotic stroke includes a. sensory disturbance. b. a history of hypertension. c. presence of motor weakness. d. sudden onset of severe headache.

answer

*d. sudden onset of severe headache.* Rationale: A hemorrhagic stroke usually causes a sudden onset of symptoms, which include neurologic deficits, headache, nausea, vomiting, decreased level of consciousness, and hypertension. Ischemic stroke symptoms may progress in the first 72 hours as infarction and cerebral edema increase.

question

Bridge to NCLEX question: 4. A patient with right-sided hemiplegia and aphasia resulting from a stroke most likely has involvement of the a. brainstem. b. vertebral artery. c. left middle cerebral artery. d. right middle cerebral artery.

answer

*c. left middle cerebral artery.* Rationale: If the middle cerebral artery is involved in a stroke, the expected clinical manifestations include aphasia, motor and sensory deficit, and hemianopsia on the dominant side and include neglect, motor and sensory deficit, and hemianopsia on the nondominant side.

question

Bridge to NCLEX question: The nurse explains to the patient with a stroke who is scheduled for angiography that this test is used to determine the a. presence of increased ICP. b. site and size of the infarction. c. patency of the cerebral blood vessels. d. presence of blood in the cerebrospinal fluid.

answer

*c. patency of the cerebral blood vessels.* Rationale: Angiography provides visualization of cerebral blood vessels and can help estimate perfusion and detect filling defects in the cerebral arteries.

question

Bridge to NCLEX question: 6. A patient experiencing TIAs is scheduled for a carotid endarterectomy. The nurse explains that this procedure is done to a. decrease cerebral edema. b. reduce the brain damage that occurs during a stroke in evolution. c. prevent a stroke by removing atherosclerotic plaques blocking cerebral blood flow. d. provide a circulatory bypass around thrombotic plaques obstructing cranial circulation.

answer

*c.prevent a stroke by removing atherosclerotic plaques blocking cerebral blood flow.* Rationale: In a carotid endarterectomy, the atheromatous lesion is removed from the carotid artery to improve blood flow.

question

Bridge to NCLEX question: For a patient who is suspected of having a stroke, one of the most important pieces of information that the nurse can obtain is a. time of the patient's last meal. b. time at which stroke symptoms first appeared. c. patient's hypertension history and management. d. family history of stroke and other cardiovascular diseases.

answer

*b. time at which stroke symptoms first appeared.* Rationale: During initial evaluation, the most important point in the patient's history is the time since onset of stroke symptoms. If the stroke is ischemic, recombinant tissue plasminogen activator (tPA) must be administered within 3 to 4.5 hours of the onset of clinical signs of ischemic stroke; tPA reestablishes blood flow through a blocked artery and prevents brain cell death in patients with acute onset of ischemic stroke.

question

Bridge to NCLEX question: Bladder training in a male patient who has urinary incontinence after a stroke includes a. limiting fluid intake. b. keeping a urinal in place at all times. c. assisting the patient to stand to void. d. catheterizing the patient every 4 hours.

answer

*c. assisting the patient to stand to void.* Rationale: In the acute stage of stroke, the primary urinary problem is poor bladder control and incontinence. Nurses should promote normal bladder function and avoid the use of indwelling catheters. A bladder retraining program consists of (1) adequate fluid intake, with most fluids administered between 7:00 am and 7:00 pm; (2) scheduled toileting every 2 hours with the use of a bedpan, commode, or bathroom; and (3) noting signs of restlessness, which may indicate the need for urination. Intermittent catheterization may be used for urinary retention (not urinary incontinence). During the rehabilitation phase after a stroke, nursing interventions focused on urinary continence include (1) assessment for bladder distention by palpation; (2) offering the bedpan, urinal, commode, or toilet every 2 hours during waking hours and every 3 to 4 hours at night; (3) using a direct command to help the patient focus on the need to urinate; (4) assistance with clothing and mobility; (5) scheduling most fluid intake between 7:00 am and 7:00 pm; and (6) encouraging the usual position for urinating (i.e., standing for men and sitting for women).

question

Bridge to NCLEX question: Common psychosocial reactions of the stroke patient to the stroke include (select all that apply) a. depression. b. disassociation. c. intellectualization. d. sleep disturbances. e. denial of severity of stroke.

answer

*a. depression, d. sleep disturbances, e. denial of severity of stroke* Rationale: The patient with a stroke may experience many losses, including sensory, intellectual, communicative, functional, role behavior, emotional, social, and vocational losses. Some patients experience long-term depression, manifesting symptoms such as anxiety, weight loss, fatigue, poor appetite, and sleep disturbances. The time and energy required to perform previously simple tasks can result in anger and frustration. Frustration and depression are common in the first year after a stroke. A stroke is usually a sudden, extremely stressful event for the patient, caregiver, family, and significant others. The family is often affected emotionally, socially, and financially as their roles and responsibilities change. Reactions vary considerably but may involve fear, apprehension, denial of the severity of stroke, depression, anger, and sorrow.

question

Pre-test questions: The nurse in a primary care provider's office is assessing several patients today. Which patient is most at risk for a stroke? A) A 92-year-old female who takes warfarin (Coumadin) for atrial fibrillation. B) A 28-year-old male who uses marijuana after chemotherapy to control nausea. C) A 42-year-old female who takes oral contraceptives and has migraine headaches. D) A 72-year-old male who has hypertension and diabetes mellitus and smokes tobacco.

answer

*D) A 72-year-old male who has hypertension and diabetes mellitus and smokes tobacco.* Rationale: Stroke risk increases after 65 years of age. Strokes are more common in men. Hypertension is the single most important modifiable risk factor for stroke. Diabetes mellitus is a significant stroke risk factor; and smoking nearly doubles the risk of a stroke. Other risk factors include drug abuse (especially cocaine), high-dose oral contraception use, migraine headaches, and untreated heart disease such as atrial fibrillation.

question

Pre-test questions: The nurse is teaching a senior citizen's group about signs and symptoms of a stroke. Which statement by the nurse would provide accurate information? A) "Take the person to the hospital if a headache lasts for more than 24 hours." B) "Stroke symptoms usually start when the person is awake and physically active." C) "A person with a transient ischemic attack has mild symptoms that will go away." D) "Call 911 immediately if a person develops slurred speech or difficulty speaking."

answer

*D) "Call 911 immediately if a person develops slurred speech or difficulty speaking."* Rationale: Medical assistance should be obtained immediately for someone with signs and symptoms of a stroke such as sudden numbness; weakness; paralysis of the face, arm, or leg (especially on one side of the body); sudden confusion; trouble speaking or understanding; slurred speech; sudden trouble seeing in one or both eyes; sudden trouble walking; dizziness; loss of balance or coordination; or a sudden, severe headache with no known cause. A person with signs and symptoms of a transient ischemic attack should seek medical attention immediately because it is unknown if the symptoms will resolve or persist and progress to a stroke. Onset of signs and symptoms of a stroke vary depending on the type. Onset of an ischemic thrombotic stroke usually occurs at rest. Onset of an ischemic embolic stroke is not related to rest or activity, and onset of a hemorrhagic stroke usually occurs with activity.

question

Pre-test questions: The physician orders alteplase (Activase) for a 58-year-old man diagnosed with an acute ischemic stroke. Which nursing action is most appropriate? A) Administer the medication by an IV route at 15 mL/hr for 24 hours. B) Insert two or three large-bore IV catheters before administering the medication. C) If gingival bleeding occurs, discontinue the medication and notify the physician. D) Reduce the medication infusion rate for a systolic blood pressure above 180 mm Hg.

answer

*B) Insert two or three large-bore IV catheters before administering the medication.* Rationale: Before giving alteplase, the nurse should start two or three large bore IVs. Bleeding is a major complication with fibrinolytic therapy, and venipunctures should not be attempted after alteplase is administered. Altepase is administered IV with an initial bolus dose followed by an infusion of the remaining medication within the next 60 minutes. Gingival bleeding is a minor complication and may be controlled with pressure or ice packs. Control of blood pressure is critical prior to altepase administration and for the following 24 hours. Before administering altepase, a systolic pressure above 180 mm Hg or diastolic pressure above 110 mm Hg requires aggressive blood pressure treatment to reduce the risk of cerebral hemorrhage.

question

Pre-test questions: The nurse observes a student nurse assigned to initiate oral feedings for a 68-year-old woman with an ischemic stroke. The nurse should intervene if she observes the student nurse... A) giving the patient 8 ounces of ice water to swallow. B) telling the patient to perform a chin tuck before swallowing. C) assisting the patient to sit in a chair before feeding the patient. D) assessing cranial nerves IX and X before the patient attempts to eat.

answer

*A) giving the patient 8 ounces of ice water to swallow.* Rationale: The majority of patients after a stroke have dysphagia. The gag reflex and swallowing ability (cranial nerves IX and X) should be assessed before the first oral feeding. To assess swallowing ability, the nurse should elevate the head of the bed to an upright position (unless contraindicated) and give the patient a very small amount (not 8 ounces) of crushed ice or ice water to swallow. The patient should remain in a high Fowler's position, preferably in a chair with the head flexed forward, for the feeding and for 30 minutes following.

question

Pre-test questions: A 74-year-old man who has right-sided extremity paralysis related to a thrombotic stroke develops constipation. Which action should the nurse take first? A) Assist the patient to the bathroom every 2 hours. B) Provide incontinence briefs to wear during the day. C) Administer a bisacodyl (Dulcolax) rectal suppository every day. D) Arrange for several servings per day of cooked fruits and vegetables.

answer

*D) Arrange for several servings per day of cooked fruits and vegetables.* Rationale: Patients after a stroke frequently have constipation. Dietary management includes the following: fluid intake of 2500 to 3000 mL daily, prune juice (120 mL) or stewed prunes daily, cooked fruit three times daily, cooked vegetables three times daily, and whole-grain cereal or bread three to five times daily. Patients with urinary incontinence should be assisted to the bathroom every 2 hours when appropriate. Suppositories may be ordered for short-term management if the patient does not respond to increased fluid and fiber. Incontinence briefs are indicated as a short-term intervention for urinary incontinence.

question

NCLEX Review Questions: Which modifiable risk factors for stroke would be most important for the nurse to include when planning a community education program? A) Hypertension B) Hyperlipidemia C) Alcohol consumption D) Oral contraceptive use

answer

*A) Hypertension* Rationale: Hypertension is the single most important modifiable risk factor, but it is still often undetected and inadequately treated. The public is often more aware of hyperlipidemia and oral contraceptive use as risk factors for stroke. Alcohol is also a modifiable risk factor.

question

NCLEX Review Questions: The nurse would expect to find what clinical manifestation in a patient admitted with a left-sided stroke? A) Impulsivity B) Impaired speech C) Left-side neglect D) Short attention span

answer

*B) Impaired speech* Rationale: Clinical manifestations of left-sided brain damage include right hemiplegia, impaired speech/language, impaired right/left discrimination, and slow and cautious performance. Impulsivity, left-sided neglect, and short attention span are all manifestations of right-sided brain damage.

question

NCLEX Review Questions: The nurse is discharging a patient admitted with a transient ischemic attack (TIA). For which medications might the nurse expect to provide discharge instructions (select all that apply)? Clopidogrel (Plavix) Enoxaparin (Lovenox) Dipyridamole (Persantine) Enteric-coated aspirin (Ecotrin) Tissue plasminogen activator (tPA)

answer

* Clopidogrel (Plavix), Dipyridamole (Persantine), Enteric-coated aspirin (Ecotrin)* Rationale: Aspirin is the most frequently used antiplatelet agent. Other drugs to prevent clot formation include clopidogrel (Plavix), dipyridamole (Persantine), ticlopidine (Ticlid), combined dipyridamole and aspirin (Aggrenox), and anticoagulant drugs, such as oral warfarin (Coumadin). Tissue plasminogen activator is a fibrinolytic medication used to treat ischemic stroke not prevent TIAs or strokes.

question

NCLEX Review Questions: Which intervention is most appropriate when communicating with a patient suffering from aphasia following a stroke? A) Present several thoughts at once so that the patient can connect the ideas. B) Ask open-ended questions to provide the patient the opportunity to speak. C) Finish the patient's sentences to minimize frustration associated with slow speech. D) Use simple, short sentences accompanied by visual cues to enhance comprehension.

answer

*D) Use simple, short sentences accompanied by visual cues to enhance comprehension.* Rationale: When communicating with a patient with aphasia, the nurse should present one thought or idea at a time. Ask questions that can be answered with a "yes," "no," or simple word. Use visual cues and allow time for the individual to comprehend and respond to conversation.

question

NCLEX Review Questions: Computed tomography (CT) of a 68-year-old male patient's head reveals that he has experienced a hemorrhagic stroke. What is the priority nursing intervention in the emergency department? A) Maintenance of the patient's airway B) Positioning to promote cerebral perfusion C) Control of fluid and electrolyte imbalances D) Administration of tissue plasminogen activator (tPA)

answer

*A) Maintenance of the patient's airway* Rationale: Maintenance of a patent airway is the priority in the acute care of a patient with a hemorrhagic stroke. It supersedes the importance of fluid and electrolyte imbalance and positioning. tPA is contraindicated in hemorrhagic stroke.

question

NCLEX Review Questions: A female patient has left-sided hemiplegia following an ischemic stroke that she experienced 4 days earlier. How should the nurse best promote the health of the patient's integumentary system? A) Position the patient on her weak side the majority of the time. B) Alternate the patient's positioning between supine and side-lying. C) Avoid the use of pillows in order to promote independence in positioning. D) Establish a schedule for the massage of areas where skin breakdown emerges.

answer

*B) Alternate the patient's positioning between supine and side-lying.* Rationale: A position change schedule should be established for stroke patients. An example is side-back-side, with a maximum duration of 2 hours for any position. The patient should be positioned on the weak or paralyzed side for only 30 minutes. Pillows may be used to facilitate positioning. Areas of skin breakdown should never be massaged.

question

NCLEX Review Questions: Which sensory-perceptual deficit is associated with left-sided stroke (right hemiplegia)? A) Overestimation of physical abilities B) Difficulty judging position and distance C) Slow and possibly fearful performance of tasks D) Impulsivity and impatience at performing tasks

answer

*C) Slow and possibly fearful performance of tasks* Rationale: Patients with a left-sided stroke (right hemiplegia) commonly are slower in organization and performance of tasks and may have a fearful, anxious response to a stroke. Overconfidence, spatial disorientation, and impulsivity are more commonly associated with a right-sided stroke.

question

NCLEX Review Questions: The female patient has been brought to the ED with a sudden onset of a severe headache that is different from any other headache she has had previously. When considering the possibility of a stroke, which type of stroke should the nurse know is most likely occurring? A) TIA B) Embolic stroke C) Thrombotic stroke D) Subarachnoid hemorrhage

answer

*D) Subarachnoid hemorrhage* Rationale: Headache is common in a patient who has a subarachnoid hemorrhage or an intracerebral hemorrhage. A TIA is a transient loss of neurologic function usually without a headache. A headache may occur with an ischemic embolic stroke, but severe neurologic deficits are the initial symptoms. The ischemic thrombotic stroke manifestations progress in the first 72 hours as infarction and cerebral edema increase.

question

NCLEX Review Questions: The patient with diabetes mellitus has had a right-sided stroke. Which nursing intervention should the nurse plan to provide for this patient related to expected manifestations of this stroke? A) Safety measures B) Patience with communication C) Mobility assistance on the right side D) Place food in the left side of patient's mouth.

answer

*A) Safety measures* Rationale: A patient with a right-sided stroke has spatial-perceptual deficits, tends to minimize problems, has a short attention span, is impulsive, and may have impaired judgment. Safety is the biggest concern for this patient. Hemiplegia occurs on the left side of this patient's body. The patient with a left-sided stroke has hemiplegia on the right, is more likely to have communication problems, and needs mobility assistance on the right side with food placed on the left side if the patient needs to be fed after a swallow evaluation has taken place.

question

NCLEX Review Questions: The nurse is planning psychosocial support for the patient and family of the patient who suffered a stroke. What factor will most likely have the greatest impact on positive family coping with the situation? A) Specific patient neurologic deficits B) The patient's ability to communicate C) Rehabilitation potential of the patient D) Presence of complications of a stroke

answer

*C) Rehabilitation potential of the patient* Rationale: Although a patient's neurologic deficit might initially be severe after a stroke, the ability of the patient to recover is most likely to positively impact the family's coping with the situation. Providing explanations and emotional support beginning in the acute phase through the rehabilitation phase will facilitate coping. Emphasizing successes will offer the most realistic hope for the patient's rehabilitation and helps maintain hope for the patient's future abilities.
