A diagnosis of a ruptured cerebral aneurysm has been made in a patient with manifestations of a stroke. The nurse anticipates that treatment options that would be evaluated for the patient include: A. hyperventilation therapy B. surgical clipping of the aneurysm C. administration of hyperosmotic agents D. administration of thrombolytic therapy

B: Surgical clipping of they aneurysm Surgical management with clipping of an aneurysm to decrease re bleeding and vasospasm is an option for a stroke cause by rupture of a cerebral aneurysm. Placement of coils into the lumens of the aneurysm by intercentional radiologists is increasing in popularity. Hyperventilation therapy would increase vasodilation and the potential for hemorrhage. Thrombolytic therapy would be absolutely contraindicated, and if a vessel is patent, osmotic diuretics may leak into tissue, pulling fluid out of the vessel and increasing edema.

A patient is admitted to the hospital with a left hemiplegia. To determine the size and location and to ascertain whether a stroke is ischemic or hemorrhagic, the nurse anticipates that the health care provider will request a A. CT scan B. lumbar puncture C. cerebral arteriogram D. positron emission tomography (PET)

A: CT scan A CT scan is the most commonly used diagnostic test to determine the size and location of the lesion and to differentiate a thrombotic stroke from a hemorrhagic stroke. Positron emission tomography (PET) will show the metabolic activity of the brain and provide a depiction of the extent of tissue damage after a stroke. Lumbar punctures are not performed routinely because of the chance of increased intracranial pressure causing herniation. Cerebral arteriograms are invasive and may dislodge an embolism or cause further hemorrhage; they are performed only when no other test can provide the needed information.

An oral anticoagulant medication. B. A thrombolytic medication. C. An anti-hyperuricemic medication. D. A beta-blocker medication.

A. An oral anticoagulant medication.

A patient has ICP monitoring with an intraventricular catheter. A priority nursing intervention for the patient is A. aseptic technique to prevent infection B. constant monitoring of ICP waveforms C. removal of CSF to maintain normal ICP D. sampling CSF to determine abnormalities

A. Aseptic technique to prevent infection- An intraventricular catheter is a fluid coupled system that can provide direct access for microorganisms to enter the ventricles of the brain, and aseptic technique is a very high nursing priority to decrease the risk for infection. Constant monitoring of ICP waveforms is not usually necessary, and removal of CSF for sampling or to maintain normal ICP is done only when specifically ordered

The assistant places her hand under the client's right axilla to help him/her move up in bed. B. The assistant places the client on the back with the client's head to the side. C. The assistant places a gait belt around the client's waist prior to ambulating. D. The assistant praises the client for attempting to perform ADL's independently.

A. The assistant places her hand under the client's right axilla to help him/her move up in bed. Why? The patient has right-sided paralysis.

A client who had a craniotomy 2 days earlier is receiving mannitol intravenously to decrease ICP. Which diagnostic lab value should be monitored while the client is receiving the medication? A. Serum osmolarity B. WBC count C. Serum cholesterol D. Electrolytes & fluids E. Erythrocyte sedimentation rate (ESR)

A. serum osmolarity Why? Mannitol is an osmotic diuretic and increases the serum osmolarity and pulls fluid from the tissues, decreasing cerebral edema. Serum osmolarity levels are assessed as a parameter to determine proper dosage.

During the acute phase of a stroke, the nurse assesses the patient's vital signs and neurologic status every 4 hours. A cardiovascular sign that the nurse would see as the body attempts to increase cerebral blood flow is A. hypertension B. fluid overload C. cardiac dysrhythmias D. S3 and S4 heart sounds

A: Hypertension SNS!!! The body responds to the vasopasm and a decreased circulation to the brain that occurs with a stroke by increasing the BP, frequently resulting in hypertension. The other options are important cardiovascular factors to assess, but they do not result from impaired cerebral blood flow.

Which patient is most at risk for stroke? A. A 32 year old woman with a BMI of 34, who smokes and has unregulated T2DM. B. A 72 year old African American male with HTN, a family history of stroke, who currently has sickle cell anemia. C.

The nurse recognizes the presence of Cushing's triad in the patient with A. Increased pulse, irregular respiration, increased BP B. decreased pulse, irregular respiration, increased pulse pressure C. increased pulse, decreased respiration, increased pulse pressure D. decreased pulse, increased respiration, decreased systolic BP

B. Cushing's triad consists of three vital sign measures that reflect ICP and its effect on the medulla, the hypothalamus, the pons, and the thalamus. Because these structures are very deep, Cushing's triad is usually a late sign of ICP. The signs include an increasing systolic BP with a widening pulse pressure, a bradycardia with a full and bounding pulse, and irregular respirations.

B. Monroe Kellie

A client seeks medical attention at an ER after experiencing right-sided weakness and slurred speech. The client receives a diagnosis of ischemic stroke and is evaluated for treatment with thrombolytic therapy. A definite contraindication for thrombolytic therapy is: A. a normal CT scan of the brain B. a serious head injury 4 weeks earlier C. a hx of DM D. onset of neurological deficits 2 hours earlier

B. a serious head injury 4 weeks earlier Why? Contraindications to thrombolytic therapy for a client with ischemic stroke include a serious head injury within the previous 3 months, This would put the patient at risk of developing serious bleeding problems (specifically hemorrhage). A negative CT scan and onset of neurological deficits within 3 hours are indications of administering thrombolytic therapy. History of DM is not a contraindication.

C. the brain area perfused by the affected artery

Which intervention should the nurse delegate to the LPN when caring for a patient following an acute stroke? A. assess the patient's neurologic status B. assess the patient's gag reflex before beginning feeding C. administer ordered antihypertensives and platelet inhibitors D. teach the patient's caregivers strategies to minimize unilateral neglect

C: Administer ordered antihypertensives and platelet inhibitors Medication administration is within the scope of practice for an LPN. Assessment and teaching are within the scope of practice for the RN.

The incidence of ischemic stroke in patients with TIAs and other risk factors is reduced with administration of A. furosemide (Lasix) B. lovastatin (Mevacor) C. daily low dose aspirin D. nimodipine (Nimotop)

C: Daily low dose aspirin The administration of antiplatelet agents, such as aspirin, dipyridamole (Persantine), and ticlopdipine (Ticlid), reduces the incidence of stroke in those at risk. Anticoagulants are also used for prevention of embolic strokes but increase the risk for hemorrhage. Diuretics are not indicated for stroke prevention other than for their role in controlling BP, and antilipemic agents have bot been found to have a significant effect on stroke prevention. The calcium channel blocker nimodipine is used in patients with subarachnoid hemorrhage to decrease the effects of vasospasm and minimize tissue damage.

A patient with a stroke has a right sided hemiplegia. The nurse prepares family members to help control behavior changes seen with this type of stroke by teaching them to A. ignore undesirable behaviors manifested by the patient B. provide directions to the patient verbally in small steps C. distract the patient from inappropriate emotional responses D. supervise all activities before allowing the patient to pursue them independently

C: Distract the patient from inappropriate emotional responses- patients with left-sided brain damage from stroke often experience emotional lability, inappropriate emotional responses, mood swings, and uncontrolled tears or laughter disproportionate or out of context with the situation. The behavior is upsetting and embarrassing to both the patient and the family, and the patient should be distracted to minimize its presence. Patients with right-brain damage often have impulsive, rapid behavior that supervision and direction.

A carotid endarterectomy is being considered as a treatment for a patient who has had several TIAs. The nurse explains to the patient that this surgery A. is used to restore blood to the brain following an obstruction of a cerebral artery B. involves intracranial surgery to join a superficial extracranial artery to an intracranial artery C. involves removing an atherosclerotic plaque in the carotid artery to prevent an impending stroke D. is sued to open a stenosis in a carotid artery with a balloon and stent to restore cerebral circulation

C: Involves removing an atherosclerotic plaque in the carotid artery to prevent an impending stroke An endarterectomy is a removal of an atherosclerotic plaque, and plaque in the carotid artery may impair circulation enough to cause a stroke. A carotid endarterectomy is performed to prevent a cerebrovascular accident (CVA), as are most other surgical procedures. An extacranial-intracranial bypass involves cranial surgery to bypass a sclerotic intacranial artery. Percutaneous transluminal angioplasty uses a balloon to compress stenotic areas in the carotid and vertebrobasilar arteries and often includes inserting a stent to hold the artery open.

A patient with right hemisphere stroke has a nursing diagnosis of unilateral neglect related to sensory perceptual deficits. During the patient's rehabilitation, it is important for the nurse to A. avoid positioning the patient on the affected side B. place all objects for care on the patient's unaffected side C. teach the patient to care consciously for the affected side D. protect the affected side from injury with pillows and supports

C: Teach the patient to care consciously for the affected side Unilateral neglect, or neglect syndrome, occurs when the patient with a stroke is unaware of the affected side of the body, which puts the patient at risk for injury. During the acute phase, the affected side is cared for by the nurse with positioning and support, during rehabilitation the patient is taught to care consciously for and attend to the affected side of the body to protect it from injury. Patients may be positioned on the affected side for up to 30 minutes.

A patient was diagnosed with a left cerebral hemorrhage. Which topics are most appropriate for the nurse to include in patient and family teaching? Select all that apply. A. how to use a sign board B. transfer techniques C. information about impulse control D. time adjustment to complete activities E. safety precautions for transferring

Correct Answer: A. how to use a sign board B. transfer techniques D. time adjustment to complete activities E. safety precautions for transferring Rationale: The left cerebral hemisphere is responsible for the language center, calculation skills, and thinking/reasoning abilities. Reading and speaking could be compromised if there is left-sided brain damage. The patient also might display overcautious behavior and might be slow to respond or complete activities. Transfer techniques would apply regardless of the side involved. Impulse control problems can arise with right-sided involvement.

A post-stroke patient is going home on oral Coumadin (warfarin). During discharge teaching, which statement by the patient reflects an understanding of the effects of this medication? A. "I will stop taking this medicine if I notice any bruising." B. "I will not eat spinach while I'm taking this medicine." C. "It will be OK for me to eat anything, as long as it is low fat." D. "I'll check my blood pressure frequently while taking this medication."

Correct Answer: B. "I will not eat spinach while I'm taking this medicine." Rationale: Warfarin is a vitamin K antagonist. Green, leafy vegetables contain vitamin K, and will therefore interfere with the therapeutic effects of the drug. Bruising is a common side effect, and the drug should not be stopped unless by prescriber order. Low-fat foods do not interfere with warfarin therapy, which is not prescribed to affect the blood pressure.

A nurse is teaching a wellness class and is covering the warning signs of stroke. A patient asks, "What is the most important thing for me to remember?" Which is an appropriate response by the nurse? A. "Know your family history." B. "Keep a list of your medications." C. "Be alert for sudden weakness or numbness." D. "Call 911 if you notice a gradual onset of paralysis or confusion."

Correct Answer: C. "Be alert for sudden weakness or numbness." Rationale: Warning signs of stroke include sudden weakness, paralysis, loss of speech, confusion, dizziness, unsteadiness, and loss of balance the key word is sudden. Family history and past medical history can be indicators for risk, but they are not warning signs of stroke. Gradual onset of symptoms is not indicative of a stroke.

The nurse is caring for a patient with increased intracranial pressure (ICP). The nurse realizes that some nursing actions are contraindicated with ICP. Which nursing action should be avoided? A. Reposition the patient every two hours. B. Position the patient with the head elevated 30 degrees. C. Suction the airway every two hours per standing orders. D. Provide continuous oxygen as ordered.

Correct Answer: C. Suction the airway every two hours per standing orders. Rationale: Suctioning further increases intracranial pressure; therefore, suctioning should be done to maintain a patent airway but not as a matter of routine. Maintaining patient comfort by frequent repositioning as well as keeping the head elevated 30 degrees will help to prevent (or even reduce) ICP. Keeping the patient properly oxygenated may also help to control ICP.

The family of a patient who has had a brain attack (CVA) asks if the patient will ever talk again. The nurse should do which of the following? A. Explain that the patient's speech will return to normal with time. B. Explain that it is difficult to know how far the patient will progress. C. Tell the family that nurses cannot discuss such issues. Tell them to ask the physician. D. Tell the family what they see today is all they can expect.

Correct Answer: B. Explain that it is difficult to know how far the patient will progress. Rationale: Therapeutic communication is needed. It is important to allow hope but be honest by not promising progress, since no one knows how much the patient will improve. Progress may depend on the extent and the areas affected. The nurse does not know that speech will return in time. It is not therapeutic to tell the family to ask the physician, and it does not display a professional, caring attitude.

A patient is admitted with signs of a stroke (CVA). On admission, vital signs were blood pressure 128/70, pulse 68, and respirations 20. Two hours later the patient is not awake, has a blood pressure of 170/70, pulse 52, and the left pupil is now slower than the right pupil in reacting to light. These findings suggest which of the following? A. impending brain death B. decreasing intracranial pressure C. stabilization of the patient's condition D. increased intracranial pressure

Correct Answer: D. increased intracranial pressure Rationale: Rising systolic blood pressure, falling pulse, and a pupil that has become sluggish suggest increasing intracranial pressure (IICP). This is an emergency situation that requires notification of the physician. This is an emergency situation that requires intervention as the patient's condition is becoming more unstable. Brain death is diagnosed by lack of brain waves and inability to maintain vital function.

D. Balanced, essential nutrition in a form that the patient can tolerate= A patient with increased ICP is in a hypermetabolic and hypercatabolic state and needs adequate glucose to maintain fuel for the brain and other nutrients to meet metabolic needs. Malnutrition promotes cerebral edema, and if a patient cannot take oral nutrition, other means of providing nutrition should be used, such as tube feedings or parenteral nutrition. Glucose alone is not adequate to meet nutritional requirements, and 5% dextrose solutions may increase cerebral edema by lowering serum osmolarity. Patients should remain in a normovolemic fluid state with close monitoring of clinical factors such as urine output, fluid intake, serum and urine osmolality, serum electrolytes, and insensible losses.

D: Helping the patient and family understand the significance of residual stroke damage to promote problem solving and planning The patient and family need accurate and complete information about the effects of the stroke to problem solve and make plans for chronic care of the patient. It is uncommon for patients with major strokes to return completely to pre stroke function, behaviors, and role, and both the patient and family will mourn these losses. The patient's specific needs for care must be identified, and rehabilitation efforts should be continued at home. Family therapy and support groups may be helpful for some patients and families.

A patient's wife asks the nurse why her husband did not receive the clot busting medication (tPA) she has been reading about. Her husband is diagnosed with a hemorrhagic stroke.

You should discuss the treatment of your husband with your doctor D. The medication you are talking about dissolves clots and could cause more bleeding in your husband's head

D: The medication you are talking about dissolves clots and could cause more bleeding in your husband's head tPA dissolves clots and increases the risk for bleeding. It is not used with hemorrhagic strokes. If the patient had a thrombotic/embolic stroke the time frame would be important as well as a history of surgery. The nurse should answer the question as accurately as possible and then encourage the individual to talk with the primary care physician if he or she has further questions.

A: Place objects on the right side within the patient's field of vision The presence of homonymous hemianopia in a patient with right-hemisphere brain damage causes a loss of vision in the left field. Early in the care of the patient, objects should be placed on the right side of the patient in the field of vision, and the nurse should approach the patient from the right side. Later in treatment, patients should be taught to turn the head and scan the environment and should be approached from the affected side to encourage head turning. Eye patches are used if patients have diplopia (double vision).
