Stroke 2019 Flashcards
(28 cards)
The single most important non-modifiable risk factor for stroke worldwide is
Age
Which modifiable risk factor is the leading cause of stroke
Hypertension
The vascular supply of the lower limb motor strip is supplied by which cerebral artery
Anterior
Poor prognosis for upper limb motor recovery following a stroke include
Complete arm paralysis at onset
The bobath and Brunnstrom Approach to movement therapy differ primarily in their approach to
Primitive movements
Constraint induced therapy requires that patients
Be able to voluntarily move their fingers
Following a stroke, DTRs increase within
48 hours
Infarction of which blood vessel causes ipsilateral facial and contralateral body loss to pain and temperature sensation, horner’s syndrome, ataxia, vertigo and dysphagia
Posterior inferior cerebellar artery
Which of the following studies is the standard of care for imaging in acute stroke
CT scan
In the setting of a high clinical suspicion for SAH, with a negative head CT scan, what diagnostic test should you perform next?
Spinal tap
In a patient without symptoms of carotid artery stenosis, ordering a carotid US is justified by which of the following additional clinical indicators?
Asymptomatic patient with carotid bruit
After an embolism stroke, which diagnostic study is the standard of care to evaluate for secondary prevention of recurrent stroke?
Echocardiogram
Which factor is associated with improved outcomes in hemorrhagic stroke patients?
Hemorrhage in the parietal lobe less than 3 cm
Your stroke patient has weakness affecting the hand and foot more than the proximal muscles on the same side. Sensation and cognition are intact. This person most likely has a stroke in which contralateral area?
Internal capsule
A patient presents for evaluation of shoulder pain in his hemiplegic upper limb following a recent stroke. On assessment of the limb, you note hyperesthesia, unusual sweating, shoulder ROM loss, and early dystrophic changes of the skin and nails of the hand. Radiographs show patchy, periarticular demineralization in the upper limb joints except the elbow. What is the most effective treatment for this condition, in additional to intensive rehab
Sympathetic blockade of the stellate ganglion
Hemorrhagic strokes caused by HTN are typically located in the
Cerebellum
A patient has a right 3rd CN palsy, left side loss of pain and temperature, left side loss of joint position, and left side ataxia. Where is the brainstem stroke most likely located.
Right tegmentum of midbrain
Which one of the following deficits is most likely due to a posterior cerebral artery stroke
Alexia without agraphia
Akinetic mutism (Abulia) with paratonia is most likely to occur from a stroke involving the
Anterior cerebral artery
Following stroke, which region of the hemiplegic upper limb demonstrates the same direction of movement in both extensor and flexor synergy patterns?
Fingers
A 72 year old woman with a stroke has dysphagia and cannot proceed with MBS because she is too unstable to leave the ICU. A FEES is recommended. THe FEES study will be able to directly visualize:
Vocal cord function
An 80 year old man presents with mild expressive aphasia and slight right sided weakness. Symptoms resolve within 15 minutes. he is diagnosed with TIA. Carotid US demonstrates 70-99% occlusion of the left ICA and 50-70% occlusion of the Right ICA. What is the most appropriate recommendation regarding carotid endarterectomy
Left carotid endarterectomy only
A patient presents with a hoarse voice and trouble swallowing. You suspect the CNS structure involved that accounts for these symptoms is in the
Nucleus ambiguous
In patients with chronic spasticity in the wrists and fingers after a stroke, which localization method is preferred for botulinum toxin injection therapy
US and electrical stimulation
