HEMISPHERE IV-RAPID STROKE
RESPONSE EXAM WITH CORRECT ACTUAL
QUESTIONS AND CORRECTLY WELL
DEFINED ANSWERS LATEST ALREADY
GRADED A+
How long is BP elevated after stroke
24-48 hrs
Increased cardiac risk with stroke
Arrhythmias (including A-fib) observed in about 25% of
patients within 72 hrs of stroke
Cardiac troponin may elevate from autonomic dysfunction in
acute MI/heart failure
Blood glucose and stroke
Persistent hyperglycemia 24 hours following stroke is
associated with worse outcomes
Hypoglycemia can mimic stroke symptoms
Maintain glucose >60 and <180
When to raise bed 30 degrees
,Risk for
Aspiration
Cardiopulmonary issues
Increased intracranial pressure
Temperature and strokes
Fever increases metabolic demand, which may increase risk
of brain injury
Stroke mimics
Hypoglycemia
TIA
Seizure
Migraine
Toxic Metabolic Cause
Sepsis
Syncope
Mass Lesion
Conversion Disorder
AEIOU tips
Causes of mental status
A alcohol acidosis
E epilepsy, encephalopathy
I insulin
O overdose
U uremia
T tumor trauma
, I infection
P psychiatric, poisoning
S seizure, sepsis, shock, stroke
Door to needle time (thrombolytic)
60 min
Brain CT/MRI time
25 min
Imaging interpretation time
within 45 min
Initial imaging (CT) stroke
rules out cerebral hemorrhage and establish IV thrombolytic
eligibility
Advanced imaging stroke
To identify candidates for mechanical thrombectomy or
pinpoint cause of hemorrhage
Noncontract computed tomography
More widely available than MRI
Quickly detects acute brain hemorrhage
May not identify ischemia in the first few hours following
stroke
MRI
more expensive and less accessible than CT
Can detect hemorrhage and more sensitive than CT in early
