Clinical Approach to Stroke (Hon) Flashcards
What are the subtypes of stroke?
Which is more common?
1) Hemorrhagic Stroke
2) Ischemic Stroke (more common)
What are risk factors for atherosclerosis?
1) HTN
2) Smoking
3) Diabetes Mellitus
4) Hyperlipidemia
What cardiac dysrhythmia is a risk factor for stroke?
Atrial Fibrillation
Abuse of what drugs are risk factors for stroke?
1) IV drugs
2) Cocaine
3) Amphetamines
Aphasia, right sided sensory symptoms, right sided motor symptoms, and right visual field cut are symptoms of stroke in what location?
Left Hemisphere
Left hemineglect, left sided sensory symptoms, left sided motor symptoms, and left visual field cut are symptoms of stroke in what location?
Right Hemisphere
Ipsilateral ataxia, vertigo, and nystagmus are symptoms of stroke in what location?
Cerebellar
Cranial nerve findings with contralateral hemisensory or hemimotor symptoms, and vertigo are symptoms of stroke in what location?
Brainstem
What is common in acute ischemic stroke and in most cases should not be treated?
Why should it not be treated?
1) Acute HTN
2) The area of infarction may have lost autoregulatory function, so that “normal” BP may be relatively hypotensive in the brain
What should the IV fluids not include in stroke patients because it is associated with worse neurologic outcomes?
Glucose
Determining where the patient is on the NIH stroke scale is important for?
If using tPA or intra-arterial intervention
What does a score of < 10 on the NIH stroke scale entail?
A score > 20?
1) 2-3% risk of hemorrhage
2) 17% risk of hemorrhage
What are some other causes that can present like stroke?
1) Seizure
2) Migraine
3) Hypoglycemia
4) Hepatic issues
When should tPA be given to a stroke patient?
Within 3-4.5 hours of the onset of symptoms
What are clinical situations in which warfarin (or one of the newer generation anticoagulants) is generally indicated?
1) Atrial Fibrillation
2) Prosthetic Valve
3) M.I.
4) Atrial septal defect
5) Hypercoagulable state
6) Large vessel disease
7) Aortic arch disease
