Chapter 17- Cerebrovascular Accident Questions with Answers cerebrovascular accident (CVA) - Correct answer result of an interruption of blood flow to the brain; decreased supply of oxygen and nutrients to brain tissues TIA - Correct answer transient ischemic attack; brief blockage of blood flow to the brain anterior supply to the brain - Correct answer front, top, and side portion of the cerebral hemispheres; carotid artier posterior supply to the brain - Correct answer brain stem, cerebellum, posterior and underside of the cerebral hemispheres; vertebral artier found wishing the vertebral column thrombosis, embolism, and lacunar - Correct answer What are the 3 types of ischemic stroke? ischemic stroke - Correct answer What is the most common type of CVA? Results in cerebral infarction (brain tissue death) Blood circulation to an area of the brain is obstructed Results in ischemia (lack of blood flow, oxygen, nutrients) Impacts the immediate surrounding brain tissue that vessel supplies Peripheral tissue damage caused by edema, swelling, increased ICP - Correct answer What does an ischemic stroke result in? thrombosis - Correct answer when a blood clot forms in one of the arteries directly supplying brain tissue; result in ischemia to tissues that vessel supplies communicating as. and circle of Willis - Correct answer Where is there less impact of a thrombosis? arteries damages by atherosclerosis - Correct answer Where does thrombosis occur most frequently? embolism - Correct answer When a blood clot formed elsewhere in the body breaks off, travels up the blood stream, until it reaches an artery too small to pass through obstruction-->ischemia-->cerebral infarction - Correct answer What are the effects of thrombosis and embolism? Cardiac arrhythmias, atrial fibrillation, CAD, physical inactivity - Correct answer What are some conditions that increase the risk for blood clots? lacunar infarcts - Correct answer small infarcts deep within the brain structures; basal ganglia, thalamus, pons; occlusion of a single artery that supplies one of these areas hypertension (HTN) - Correct answer What is the greatest risk factor for lacunar infarcts? hemorrhagic stroke - Correct answer caused by a rupture of a blood vessel (aneurysm) intracerebral and subarachnoid - Correct answer What are the two types of hemorrhagic stroke? aneurysm - Correct answer bulging of the wall of an artery; prone to rupture hemorrhagic stroke - Correct answer Are ischemic strokes of hemorrhagic strokes more common in younger adults? intracerebral hemorrhage - Correct answer Bleeding direction into the brain tissue resulting in increased pressure on the brain Damage occurs more spherically based on the pooling of blood Symptoms appear suddenly and may be accompanied by headache, vomiting, decreased alertness - Correct answer What are the clinical sings of an intracerebral hemorrhage that are different than an ischemic? subarachnoid hemorrhage - Correct answer bleeding into the space surrounding the brain and CSF fluid (subarachnoid space); may restful in aneurysm, blood disorders and trauma headache, sleepiness, altered states of consciousness - Correct answer What are the symptoms of a Subarachnoid Hemorrhage?
