Approximately what percentage of strokes are ischemic in nature, and thus eligible for fibrinolytic therapy if the patient qualifies?
The first critical decision point in the suspected stroke algorithm is?
Consideration of fibrinolytic therapy
General assessment and stabilization of the patient
Performance and assessment of a non-contrast CT to differentiate between hemorrhagic and ischemic stroke
Review of risks and benefits of fibrinolytic therapy with patient and/or family
Which of the following would exclude the use of fibrinolytic therapy in a patient confirmed to have had an ischemic stroke?
Elevated blood pressure (systolic >160 or diastolic >90 mmHg)
Current use of an anticoagulant
Head trauma within the previous 3 months
Seizure at the onset of stroke
Signs of possible stroke may include:
Sudden severe headache with no known cause
Sudden trouble walking
Trouble speaking or understanding
All of these
If the patient woke from sleep with symptoms of stroke, when is time zero?
The time the patient woke up
The time the patient went to sleep
When the patient was last seen to be acting normal
Determined by if the patient has any health problems that could be contributing factors
Out-of-hospital acute stroke care focuses on:
Initiation of the stroke pathway and patient admission to a stroke unit if available
Ability to rapidly determine patient eligibility for fibrinolytic therapy
Consideration of new treatment options
Rapid transport to a facility capable of providing acute stroke care
