c) 190 mm Hg/120 mm Hg Elevated blood pressure (systolic >185; diastolic >110 mm Hg) is a contraindication to tPA.

Which of the following terms refer to the inability to perform previously learned purposeful motor acts on a voluntary basis? a) Agraphia b) Perseveration c) Agnosia d) Apraxia

d) Apraxia Verbal apraxia refers to difficulty in forming and organizing intelligible words although the musculature is intact. Agnosia is failure to recognize familiar objects perceived by the senses. Agraphia refers to disturbances in writing intelligible words. Perseveration is the continued and automatic repetition of an activity or word or phrase that is no longer appropriate. (less)

What would be the nurse's best answer? A) "Have your heart checked regularly." B) "Stop smoking as soon as possible." C) "Get medication to bring down your sodium levels." D) "Eat a nutritious diet."

B) "Stop smoking as soon as possible."

A preceptor is discussing stroke with a new nurse on the unit. The preceptor would tell the new nurse which cardiac dysrhythmia is associated with cardiogenic embolic strokes? A) Ventricular tachycardia B) Atrial fibrillation C) Supraventricular tachycardia D) Bundle branch block

B) Atrial fibrillation

When caring for a patient who has had a stroke, a priority is reduction of ICP. What patient position is most consistent with this goal? A) Head turned slightly to the right side B) Elevation of the head of the bed C) Position changes every 15 minutes while awake D) Extension of the neck

B) Elevation of the head of the bed

A patient diagnosed with a hemorrhagic stroke has been admitted to the neurologic ICU. The nurse knows that teaching for the patient and family needs to begin as soon as the patient is settled on the unit and will continue until the patient is discharged. What will family education need to include? A) How to differentiate between hemorrhagic and ischemic stroke B) Risk factors for ischemic stroke C) How to correctly modify the home environment D) Techniques for adjusting the patient's medication dosages at home

C) How to correctly modify the home environment

A) Place the patient in the prone position for 30 minutes/day. B) Assist the patient in acutely flexing the thigh to promote movement. C) Place a pillow in the axilla when there is limited external rotation. D) Place patient's hand in pronation.

C) Place a pillow in the axilla when there is limited external rotation.

A nurse is assisting with a community screening for people at high risk for stroke. To which of the following clients would the nurse pay most attention? a. A 60-year-old African-American man b. A 40-year-old Caucasian woman c. A 62-year-old Caucasian woman d. A 28-year-old pregnant African-American woman

a. A 60-year-old African-American man

A 70-year-old female patient with left-sided hemiparesis arrives by ambulance to the emergency department. Which action should the nurse take first? a. Monitor the blood pressure. b. Send the patient for a computed tomography (CT) scan. c. Check the respiratory rate and effort. d. Assess the Glasgow Coma Scale score.

c. Check the respiratory rate and effort. 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, and circulation) are completed.

A patient diagnosed with a stroke is ordered to receive warfarin (Coumadin). Later, the nurse learns that the warfarin is contraindicated and the order is canceled. The nurse knows that the best alternative medication to give is which of the following? a) Ticlodipine (Ticlid) b) Dipyridamole (Persantine) c) Clopidogrel (Plavix) d) Aspirin

d) Aspirin If warfarin is contraindicated, aspirin is the best option, although other medications may be used if both are contraindicated.

Which of the following is the most common side effect of tissue plasminogen activator (tPA)? a) Increased intracranial pressure (ICP) b) Hypertension c) Headache d) Bleeding

d) Bleeding Bleeding is the most common side effect of tPA. The patient is closely monitored for bleeding (at IV insertion sites, gums, urine/stools, and intracranially by assessing changes in level of consciousness). Headache, increased ICP, and hypertension are not side effects of tPA.

A client who has experienced an initial transient ischemic attack (TIA) states: "I'm glad it wasn't anything serious." Which is the best nursing response to this statement? a. "I sense that you are happy it was not a stroke". b. "People who experience a TIA will develop a stroke". c. "TIA symptoms are short-lived and resolve within 24 hours". d. "TIA is a warning sign. Let's talk about lowering your risks."

d. "TIA is a warning sign. Let's talk about lowering your risks."

A 56-year-old patient arrives in the emergency department with hemiparesis and dysarthria that started 2 hours previously, and health records show a history of several transient ischemic attacks (TIAs). The nurse anticipates preparing the patient for a. surgical endarterectomy. b. transluminal angioplasty. c. intravenous heparin administration. d. tissue plasminogen activator (tPA) infusion.

d. tissue plasminogen activator (tPA) infusion. 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.

Which of the following insults or abnormalities can cause an ischemic stroke? a) Arteriovenous malformation b) Intracerebral aneurysm rupture c) Cocaine use d) Trauma

c) Cocaine use Cocaine is a potent vasoconstrictor and may result in a life-threatening reaction, even with the individual's first use of the drug. Arteriovenous malformations are associated with hemorrhagic strokes. Trauma is associated with hemorrhagic strokes. Intracerebral aneurysm rupture is associated with hemorrhagic strokes.

A physician orders several drugs for a client with hemorrhagic stroke. Which drug order should the nurse question? a) Phenytoin (Dilantin) b) Methyldopa (Aldomet) c) Heparin sodium d) Dexamethasone (Decadron)

c) Heparin sodium Administering heparin, an anticoagulant, could increase the bleeding associated with hemorrhagic stroke. Therefore, the nurse should question this order to prevent additional hemorrhage in the brain. In a client with hemorrhagic stroke, the physician may use dexamethasone to decrease cerebral edema and pressure; methyldopa, to reduce blood pressure; and phenytoin, to prevent seizures.

Which of the following is a contraindication for the administration of tissue plasminogen activator (t-PA)? a) Systolic blood pressure less than or equal to 185 mm Hg b) Ischemic stroke c) Intracranial hemorrhage d) Age 18 years of age or older

c) Intracranial hemorrhage Intracranial hemorrhage, neoplasm, or aneurysm is a contraindication to t-PA. Clinical diagnosis of ischemic stroke, age 18 years of age or older, and a systolic BP less than or equal to 185 mm Hg are eligibility criteria. (less)

Which of the following is accurate regarding a hemorrhagic stroke? a) It is caused by a large-artery thrombosis. b) One of the main presenting symptoms is numbness or weakness of the face. c) Main presenting symptom is an "exploding headache." d) Functional recovery usually plateaus at 6 months.

c) Main presenting symptom is an "exploding headache." One of hemorrhagic stroke's main presenting symptom is an "exploding headache." In ischemic stroke, functional recovery usually plateaus at 6 months; it may be caused by a large artery thrombosis and may have a presenting symptoms of numbness or weakness of the face

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.

c. The patient reports that symptoms began with a severe headache. 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.

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).

c. oral low-dose aspirin therapy. 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.

The nurse is caring for a patient with dysphagia. Which of the following interventions would be contraindicated while caring for this patient? a) Allowing ample time to eat b) Assisting the patient with meals c) Testing the gag reflex prior to offering food or fluids d) Placing food on the affected side of mouth

d) Placing food on the affected side of mouth Interventions for dysphagia include placing food on the unaffected side of the mouth, allowing ample time to eat, assisting the patient with meals, and testing the patient's gag reflex prior to offering food or fluids.

A patient admitted with possible stroke has been aphasic for 3 hours and his current blood pressure (BP) is 174/94 mm Hg. Which order by the health care provider should the nurse question? a. Keep head of bed elevated at least 30 degrees. b. Infuse normal saline intravenously at 75 mL/hr. c. Administer tissue plasminogen activator (tPA) per protocol. d. Administer a labetalol (Normodyne) drip to keep BP less than 140/90 mm Hg.

d. Administer a labetalol (Normodyne) drip to keep BP less than 140/90 mm Hg. 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.

The nurse is preparing health education for a patient who is being discharged after hospitalization for a hemorrhagic stroke. What content should the nurse include in this education? A) Mild, intermittent seizures can be expected. B) Take ibuprofen for complaints of a serious headache. C) Take antihypertensive medication as ordered. D) Drowsiness is normal for the first week after discharge.

C) Take antihypertensive medication as ordered.

A patient with a cerebral aneurysm exhibits signs and symptoms of an increase in intracranial pressure (ICP). What nursing intervention would be most appropriate for this patient? A) Range-of-motion exercises to prevent contractures B) Encouraging independence with ADLs to promote recovery C) Early initiation of physical therapy D) Absolute bed rest in a quiet, nonstimulating environment

D) Absolute bed rest in a quiet, nonstimulating environment

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.

c. The patient's usual blood pressure (BP) is 170/94 mm Hg. 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.

The nurse is providing information about strokes to a community group. Which of the following would the nurse identify as the primary initial symptoms of an ischemic stroke? a) Footdrop and external hip rotation b) Vomiting and seizures c) Severe headache and early change in level of consciousness d) Weakness on one side of the body and difficulty with speech

d) Weakness on one side of the body and difficulty with speech The main presenting symptoms for an ischemic stroke are numbness or weakness of the face, arm, or leg, especially on one side of the body; confusion or change in mental status; and trouble speaking or understanding speech. Severe headache, vomiting, early change in level of consciousness, and seizures are early signs of a hemorrhagic stroke. Footdrop and external hip rotation are things that can occur if a stroke victim is not turned or positioned correctly.

A patient diagnosed with transient ischemic attacks (TIAs) is scheduled for a carotid endarterectomy. The nurse explains that this procedure will be done for what purpose? A) To decrease cerebral edema B) To prevent seizure activity that is common following a TIA C) To remove atherosclerotic plaques blocking cerebral flow D) To determine the cause of the TIA

C) To remove atherosclerotic plaques blocking cerebral flow

A female patient who had a stroke 24 hours ago has expressive aphasia. The nurse identifies the nursing diagnosis of impaired verbal communication. An appropriate nursing intervention to help the patient communicate is to a. ask questions that the patient can answer with "yes" or "no." b. develop a list of words that the patient can read and practice reciting. c. have the patient practice her facial and tongue exercises with a mirror. d. prevent embarrassing the patient by answering for her if she does not respond.

a. ask questions that the patient can answer with "yes" or "no." 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.

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. tPA b. aspirin c. warfarin (Coumadin) d. nimodipine

b. aspirin After a transient ischemic attack, 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.

The nurse identifies the nursing diagnosis of imbalanced nutrition: less than body requirements related to impaired self-feeding ability for a left-handed patient with left-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 right hand. d. Teach the patient the "chin-tuck" technique.

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

During the change of shift report a nurse is told that a patient has an occluded left posterior cerebral artery. The nurse will anticipate that the patient may have a. dysphasia. b. confusion. c. visual deficits. d. poor judgment.

c. visual deficits. 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.

A client is admitted with weakness, expressive aphasia, and right hemianopsia. The brain MRI reveals an infarct. The nurse understands these symptoms to be suggestive of which of the following findings? a) Left-sided cerebrovascular accident (CVA) b) Right-sided cerebrovascular accident (CVA) c) Transient ischemic attack (TIA) d) Completed Stroke

a) Left-sided cerebrovascular accident (CVA) When the infarct is on the left side of the brain, the symptoms are likely to be on the right, and the speech is more likely to be involved. If the MRI reveals an infarct, TIA is no longer the diagnosis. There is not enough information to determine if the stroke is still evolving or is complete.

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

b. to call the health care provider if stools are tarry. Clopidogrel 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

The nurse is caring for a patient who has been experiencing stroke symptoms for 60 minutes. Which action can the nurse delegate to a licensed practical/vocational nurse (LPN/LVN)? a. Assess the patient's gag and cough reflexes. b. Determine when the stroke symptoms began. c. Administer the prescribed short-acting insulin. d. Infuse the prescribed IV metoprolol (Lopressor).

c. Administer the prescribed short-acting insulin. Administration of subcutaneous medications is included in LPN/LVN education and scope of practice. The other actions require more education and scope of practice and should be done by the registered nurse (RN).

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.

c. Explain that the aspirin is ordered to decrease stroke risk. 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.

A 47-year-old patient will attempt oral feedings for the first time since having a stroke. 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.

c. assist the patient into a chair. 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.

Which disturbance results in loss of half of the visual field? a) Anisocoria b) Homonymous hemianopsia c) Nystagmus d) Diplopia

b) Homonymous hemianopsia Homonymous hemianopsia (loss of half of the visual field) may occur from stroke and may be temporary or permanent. Double vision is documented as diplopia. Nystagmus is ocular bobbing and may be seen in multiple sclerosis. Anisocoria is unequal pupils.

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

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

An emergency department nurse is interviewing a client with signs of an ischemic stroke that began 2 hours ago. The client reports that she had a cholecystectomy 6 weeks ago and is taking digoxin, coumadin, and labetelol. This client is not eligible for thrombolytic therapy for which of the following reasons? a) She is not within the treatment time window. b) She had surgery 6 weeks ago. c) She is taking digoxin. d) She is taking coumadin.

d) She is taking coumadin. To be eligible for thrombolytic therapy, the client cannot be taking coumadin. Initiation of thrombolytic therapy must be within 3 hours in clients with ischemic stroke. The client is not eligible for thrombolytic therapy if she has had surgery within 14 days. Digoxin and labetelol do not prohibit thrombolytic therapy.

The nurse practitioner advises a patient who is at high risk for a stroke to be vigilant in his medication regime, to maintain a healthy weight, and to adopt a reasonable exercise program. This advice is based on research data that shows the most important risk factor for stroke is: a) Dyslipidemia b) Obesity c) Hypertension d) Smoking

c) Hypertension Hypertension is the most modifiable risk factor for either ischemic or hemorrhagic stroke. Unfortunately, it remains under-recognized and undertreated in most communities.

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.

d. teach the family that emotional outbursts are common after strokes. 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.

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

d. Difficulty comprehending instructions 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.

The nurse is caring for a patient diagnosed with a hemorrhagic stroke. The nurse recognizes that which of the following interventions is most important? a. Elevating the head of the bed at 30 degrees b. Monitoring for seizure activity c. Administering a stool softener d. Maintaining a patent airway

d. Maintaining a patent airway

A rehabilitation nurse caring for a patient who has had a stroke is approached by the patient's family and asked why the patient has to do so much for herself when she is obviously struggling. What would be the nurse's best answer? A) "We are trying to help her be as useful as she possibly can." B) "The focus on care in a rehabilitation facility is to help the patient to resume as much self-care as possible." C) "We aren't here to care for her the way the hospital staff did; we are here to help her get better so she can go home." D) "Rehabilitation means helping patients do exactly what they did before their stroke."

B) "The focus on care in a rehabilitation facility is to help the patient to resume as much self-care as possible."

A nurse is caring for a patient diagnosed with a hemorrhagic stroke. When creating this patient's plan of care, what goal should be prioritized? A) Prevent complications of immobility. B) Maintain and improve cerebral tissue perfusion. C) Relieve anxiety and pain. D) Relieve sensory deprivation.

B) Maintain and improve cerebral tissue perfusion.

The nurse is performing stroke risk screenings at a hospital open house. The nurse has identified four patients who might be at risk for a stroke. Which patient is likely at the highest risk for a hemorrhagic stroke? A) White female, age 60, with history of excessive alcohol intake B) White male, age 60, with history of uncontrolled hypertension C) Black male, age 60, with history of diabetes D) Black male, age 50, with history of smoking

B) White male, age 60, with history of uncontrolled hypertension

During a class on stroke, a junior nursing student asks what the clinical manifestations of stroke are. What would be the instructor's best answer? a) "Clinical manifestations of a stroke depend on the area of the cortex, the affected hemisphere, the degree of blockage, and the availability of collateral circulation." b) "Clinical manifestations of a stroke generally include aphasia, one-sided flaccidity, and trouble swallowing." c) "Clinical manifestations of a stroke depend on how quickly the clot can be dissolved." d) "Clinical manifestations of a stroke are highly variable, depending on the cardiovascular health of the client."

a) "Clinical manifestations of a stroke depend on the area of the cortex, the affected hemisphere, the degree of blockage, and the availability of collateral circulation." Clinical manifestations following a stroke are highly variable and depend on the area of the cerebral cortex and the affected hemisphere, the degree of blockage (total, partial), and the presence or absence of adequate collateral circulation. (Collateral circulation is circulation formed by smaller blood vessels branching off from or near larger occluded vessels.) Clinical manifestations of a stroke do not depend on the cardiovascular health of the client or how quickly the clot can be dissolved. Clinical manifestations of a stroke are not "general" but individual.

A patient with carotid atherosclerosis asks the nurse to describe a carotid endarterectomy. Which response by the nurse is accurate? a. "The obstructing plaque is surgically removed from an artery in the neck." b. "The diseased portion of the artery in the brain is 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."

a. "The obstructing plaque is surgically removed from an artery in the neck." 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 replaced" 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 mechanical embolus removal in cerebral ischemia (MERCI) procedure.

After receiving change-of-shift report on the following four patients, which patient should the nurse see first? a. A 60-year-old patient with right-sided weakness who has an infusion of tPA prescribed b. A 50-year-old patient who has atrial fibrillation and a new order for warfarin (Coumadin) c. 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

a. A 60-year-old patient with right-sided weakness who has an infusion of tPA prescribed 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 should also be given as quickly as possible, but timing of the medications is not as critical.

A 40-year-old patient has a ruptured cerebral aneurysm and subarachnoid hemorrhage. Which intervention will be included in the care plan? a. Apply intermittent pneumatic compression stockings. b. Assist to dangle on edge of bed and assess for dizziness. c. Encourage patient to cough and deep breathe every 4 hours. d. Insert an oropharyngeal airway to prevent airway obstruction.

a. Apply intermittent pneumatic compression stockings. The patient with a subarachnoid hemorrhage usually has minimal activity to prevent cerebral vasospasm or further bleeding and is at risk for venous thromboembolism (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.

A nurse is working with a student nurse who is caring for a client with an acute bleeding cerebral aneurysm. Which action by the student nurse requires further intervention? a) Maintaining the client in a quiet environment b) Keeping the client in one position to decrease bleeding c) Positioning the client to prevent airway obstruction d) Administering I.V. fluid as ordered and monitoring the client for signs of fluid volume excess

b) Keeping the client in one position to decrease bleeding The student nurse shouldn't keep the client in one position. She should carefully reposition the client often (at least every hour). The client needs to be positioned so that a patent airway can be maintained. Fluid administration must be closely monitored to prevent complications such as increased intracranial pressure. The client must be maintained in a quiet environment to decrease the risk of rebleeding.

While providing information to a community group, the nurse tells them the primary initial symptoms of a hemorrhagic stroke are: a) Footdrop and external hip rotation b) Severe headache and early change in level of consciousness c) Weakness on one side of the body and difficulty with speech d) Confusion or change in mental status

b) Severe headache and early change in level of consciousness The main presenting symptoms for ischemic stroke are numbness or weakness of the face, arm, or leg, especially on one side of the body, confusion or change in mental status, and trouble speaking or understanding speech. Severe headache, vomiting, early change in level of consciousness, and seizures are early signs of a hemorrhagic stroke. Footdrop and external hip rotation can occur if a stroke victim is not turned or positioned correctly. (less)

A client is hospitalized when they present to the Emergency Department with right-sided weakness. Within 6 hours of being admitted, the neurologic deficits had resolved and the client was back to their presymptomatic state. The nurse caring for the client knows that the probable cause of the neurologic deficit was what? a) Cerebral aneurysm b) Transient ischemic attack c) Left-sided stroke d) Right-sided stroke

b) Transient ischemic attack A transient ischemic attack (TIA) is a sudden, brief attack of neurologic impairment caused by a temporary interruption in cerebral blood flow. Symptoms may disappear within 1 hour; some continue for as long as 1 day. When the symptoms terminate, the client resumes his or her presymptomatic state. The symptoms do not describe a left- or right-sided stroke or a cerebral aneurysm.

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.

b. Assist the patient onto the bedside commode every 2 hours. 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.

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.

b. The patient has difficulty speaking. 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.

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).

b. The patient's blood pressure (BP) is 90/50 mm Hg. 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.

For a patient who had a right hemisphere stroke, the nurse anticipates planning interventions to manage a. impaired physical mobility related to right-sided 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.

b. risk for injury related to denial of deficits and impulsiveness. The patient with right-sided brain damage typically denies any deficits and has 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.

A patient is admitted via ambulance to the emergency room of a stroke center at 1:30 p.m. with symptoms that the patient said began at 1:00 p.m. Within 1 hour, an ischemic stroke had been confirmed and the doctor ordered tPA. The nurse knows to give this drug no later than what time? a) 5:30 p.m. b) 3:00 p.m. c) 4:00 p.m. d) 2:30 p.m.

c) 4:00 p.m. (Joe's note: our slides say that TPA must be administered within 3 to 4 1⁄2 hours of onset of clinical signs of ischemic stroke so the answer could/should be 5:30 pm, right?) Tissue plasminogen activator (tPA) must be given within 3 hours after symptom onset. Therefore, since symptom onset was 1:00 pm, the window of opportunity ends at 4:00 pm.

A nurse is caring for a client who has returned to his room after a carotid endarterectomy. Which action should the nurse take first? a) Take the client's blood pressure. b) Ask the client if he has a headache. c) Ask the client if he has trouble breathing. d) Place antiembolism stockings on the client.

c) Ask the client if he has trouble breathing. The nurse should first assess the client's breathing. A complication of a carotid endarterectomy is an incisional hematoma, which could compress the trachea causing breathing difficulty for the client. Although the other measures are important actions, they aren't the nurse's top priority.

A 63-year-old patient who began experiencing right 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 a space between each answer choice [A, B, C, D].) a. Obtain computed tomography (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.

c. Administer oxygen to keep O2 saturation >95%. d. Use National Institute of Health Stroke Scale to assess patient. a. Obtain computed tomography (CT) scan without contrast. b. Infuse tissue plasminogen activator (tPA). 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.

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

c. Disabled family coping related to inadequate understanding by patient's spouse 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.

The home health nurse is caring for an 81-yr-old who had a stroke 2 months ago. Based on information shown in the accompanying figure from the history, physical assessment, and physical and occupational therapy, which problem is the highest priority? History • Well controlled type 2 diabetes for 10 years • Married 45 years; spouse has heart failure and chronic obstructive pulmonary disease Physical Assessment • Oriented to time, place, person • Speech clear •Minimal left leg weakness Physical/Occupational Therapy • Uses cane with walking • Spouse does household cleaning and cooking and assists patient with bathing and dressing a. Risk for hypoglycemia b. Impaired transfer ability c. Risk for caregiver role strain d. Ineffective health maintenance

c. Risk for caregiver role strain 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.

The nurse is caring for a patient with a history of transient ischemic attacks (TIAs) and moderate carotid stenosis who has undergone a carotid endarterectomy. Which of the following postoperative findings would cause the nurse the most concern? a) Blood pressure (BP): 128/86 mm Hg b) Neck pain: 3/10 (0 to 10 pain scale) c) Mild neck edema d) Difficulty swallowing

d) Difficulty swallowing The patient's inability to swallow without difficulty would cause the nurse the most concern. Difficulty in swallowing, hoarseness or other signs of cranial nerve dysfunction must be assessed. The nurse focuses on assessment of the following cranial nerves: facial (VII), vagus (X), spinal accessory (XI), and hypoglossal (XII). Some edema in the neck after surgery is expected; however, extensive edema and hematoma formation can obstruct the airway. Emergency airway supplies, including those needed for a tracheostomy, must be available. The patient's neck pain and mild BP elevation need addressing but would not cause the nurse the most concern. Hypotension is avoided to prevent cerebral ischemia and thrombosis. Uncontrolled hypertension may precipitate cerebral hemorrhage, edema, hemorrhage at the surgical incision, or disruption of the arterial reconstruction.

A 64-year-old client reports symptoms consistent with a transient ischemic attack (TIA) to the physician in the emergency department. After completing ordered diagnostic tests, the physician indicates to the client what caused the symptoms that brought him to the hospital. What is the origin of the client's symptoms? a) Hypertension b) Cardiac disease c) Diabetes insipidus d) Impaired cerebral circulation

d) Impaired cerebral circulation TIAs result from impaired blood circulation in the brain, which can be caused by atherosclerosis and arteriosclerosis, cardiac disease, or diabetes. The symptoms of a TIA are the result of impaired blood circulation in the brain, which may have been caused by cardiac disease. The symptoms of a TIA are the result of impaired blood circulation in the brain, which may have been caused by diabetes. The symptoms of a TIA are the result of impaired blood circulation in the brain, which may have been caused by hypertension.

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

d. Noncontrast computed tomography (CT) scan 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.

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

d. Risk for aspiration related to inability to protect airway 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.

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).

d. The patient has atrial fibrillation and takes warfarin (Coumadin). 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.
