Term
What is a stroke?
Definition
Caused by reduced cerebral blood flow that leads to brain cell death and functional disability
Term
What are the 2 types of stroke?
Definition
-Ischemic
-Hemorrhagic
Term
What is an ischemic stroke?
Definition
stroke results from an occluded artery that deprives blood flow to a certain part of the brain
Term
What is a hemorrhagic stroke?
Definition
caused by a ruptured artery, resulting in bleeding in or around the brain
Term
What is the pathophys. of an ischemic stroke?
Definition
ischemic cascade of pathological metabolic events – plaque buildup then free clot
Term
What is the pathophys of a TIA?
Definition
transient ischemic attack. the same pathophysiologic mechanism as in the ischemic cascade but symptoms are transient.
Term
What is the pathophys of the hemorrhagic stroke?
Definition
The bleeding associated with a hemorrhagic stroke interferes with normal brain metabolism
Term
What are the modifiable risk factors of strokes?
Definition
- Hypertension, smoking, diabetes, dyslipidemia, atrial fibrillation, diet, obesity, sleep apnea, and lack of exercise, birth control
Term
What are the non modifiable risk factors of stroke?
Definition
Family history, age, and race
Term
What is thrombosis?
Definition
Formation of clot in vessel. Usually in area affected by plaque—atherosclerosis
Term
What is embolic?
Definition
Blood vessel/ artery occluded by partial clot, tumor, fat, bacteria, air enters brain
Term
What is important to note about the eyes after a stroke?
Definition
• Eyes follow side of brain affected by stroke, side of body effected is the opposite then the side of the brain effected
o EX: Left sided stroke – Right side weakened, eyes go to left side

How are types of strokes determined?
Definition
based on CT (or MRI) and blood chemistries, coagulation studies, blood cell counts, and cardiac rhythm status
Term
What is the medical management of an ischemic stroke?
Definition
Thrombolysis with recombinant tissue plasminogen activator (rtPA)

Go home on anticoag/blood thinner
Term
What is the medical management of a hemorrhagic stroke?
Definition
Measures are taken to lower ICP, possibly including surgery

Go home on BP medications
Term
What is important to note about PT/INR times for a patient on Warfarin?
Definition
o PT 1.5 to 2 times control

• B/P
Term
• What aspect of an individual’s unhealthy diet is associated with an increased risk of stroke?
o Excess intake of simple carbohydrates
o Excess salt intake
o Protein deficit
o Malnutrition
Definition
o Excess salt intake
• High sodium intake has been identified as a modifiable risk factor for stroke. Protein deficits, malnutrition, and excess intake of simple carbohydrates are not directly linked to stroke.
Term
• Is the following statement true or false?
o The immediate nursing priority in the care of a patient presenting with a suspected stroke is assessment of motor function.
Definition
• False
• Rationale: Nursing assessment includes motor and sensory function, but the immediate assessment priorities are airway, breathing, and circulation.
Term
• In order to prevent the development of shoulder pain during recovery from a stroke, the nurse should:
o Avoid contact with the patient’s weak arm whenever possible
o Avoid taking the patient’s blood pressure on the affected arm
o Support the patient’s weak arm on a pillow or table
o Let the patient’s weak arm hang loose whenever possible
Definition
• C. Support the patient’s weak arm on a pillow or table
• Rationale: Many shoulder problems can be prevented by proper patient movement and positioning. The flaccid arm should be positioned on a table or with pillows while the patient is seated. Letting the weak arm dangle without support can result in injury. It is not always necessary to avoid contact or measuring blood pressure on the affected arm.
Term
• Which of the following patients is at greatest risk for a CVA?
o An obese, 32 year old Native American female with hypertension, diabetes and taking oral contraceptives.
o A 69 year old white male who smokes a pack of cigarettes a day and has no family history of strokes.
o A 24 year old African-American female on oral contraceptives.
o A 45 year old white male with a history of hypertension that is currently controlled with medication.

Term
• Items for the nurse to review when teaching a patient about warfarin therapy include
o Increase the amount of green, leafy vegetables in your diet.
o Rinse your mouth instead of brushing your teeth.
o Follow up with laboratory tests such as PT or INR to regulate warfarin dose.
o Use a new razor blade each time you shave.
Definition
• Follow up with laboratory tests such as PT or INR to regulate warfarin dose.
• Laboratory tests such as PT or INR are performed to regulate warfarin (Coumadin) dose. The patient should avoid consuming large amounts of green, leafy vegetables; broccoli; legumes; soybean oil; coffee; tea; cola; excessive alcohol; and certain nutritional supplements such as coenzyme Q10. patients are encouraged to perform oral hygiene and use a soft tooth brush to prevent gums from bleeding. patients should be instructed to use an electric razor when shaving.
Term
• A patient manifests symptoms of a thrombolic stroke. The emergency department nurse is aware that thrombolytics need to be administered in this situation within how many hours of the onset of symptoms?
o 1 hour
o 2 hours
o 3 hours
o 4 to 6 hours
Definition
• 3 hours
Term
• A patient is on heparin therapy secondary to deep vein thromboses. The nurse has the following antidote on hand in case it is needed:
o Vitamin K
o Warfarin
o Protamine sulfate
o Aminocaproic acid (Amicar)
Definition
• Protamine sulfate
Term
• Which of the following is not a contraindication to the use of thrombolytics?
o Use of acetaminophen
o Severe hypertension
o Recent cerebral vascular accident
o Warfarin therapy
Definition
• Use of acetaminophen
• Acetaminophen (Tylenol) does not interfere with the coagulation system. Contraindications for use of thrombolytics include a recent CVA, active bleeding, severe hypertension, recent history of traumatic injury, especially head injury, and anticoagulant therapy. The nurse should report if the patient takes aspirin or NSAIDs.
Term
• A patient on statin medications should be counseled to watch for which of the following, which may indicate a life-threatening adverse reaction?
o Fatigue
o Muscle aches
o Vomiting
o Scomata
Definition
• Muscle Aches
• The serious skeletal muscle adverse effect known as rhabdomyolysis has been reported with use of the statin drug class. patients should be advised to promptly report to the health care provider any unexplained muscle tenderness or weakness, especially if accompanied by fever or malaise.
Term
• Patients who are ordered to receive atorvastatin should have which of the following laboratory tests periodically monitored?
o Complete blood count
o Serum electrolytes
o Liver function studies
o Renal function studies
Definition
• Liver function studies
• Serum liver enzymes should be monitored for all patients taking statins such as atorvastatin (Lipitor); also, an annual eye examination is needed, because cataract formation may result.
Term
What is important for caring of a post stroke patient?
Definition
assisting with feeding (aspiration risk), 2 hours for toileting, fluids, etc., side lying with head elevated if you cannot breathe, ROM exercises (active and passive), put things on not affected side, position them so their muscles are stretched out (palms up/arms out), consult for PT and speech
Term
What is the goal of therapy post TIA?
Definition
Lifestyle modification.

You know it's a TIA because it resolves in 1 hr or less.
Term
Strokes with symptoms of ICP (n/v/headache) are usually what kind?
Definition
HERMORRHAGIC! There is an increase in ICP with the increase of fluid in the brain.
