Stroke

LEARNING OUTCOME: Upon completion of this continuing education course, you will demonstrate an understanding of the anatomical alterations, pathophysiology, and emergency care.

LEARNING OBJECTIVES

Identify some risk factors for stroke.

Discuss the major classifications of stroke.

Describe the structural anatomy of the normal brain and the alterations in function resulting from stroke.

Outline the pathophysiology and etiology of stroke.

Describe the components of prehospital care and evaluation of stroke

Stroke

1 / 19

Because of the broader window of treatment time and therapies available, EMS needs to reconsider:

transport and treatment times can slow down.

transport and on scene times don’t need to rush.

prehospital assessment and transport of suspected acute stroke patients to maximize the likelihood that they receive the most appropriate therapies.

prehospital assessments only.

In one study in a suburban/urban, it indicated that EMS system planners may anticipate that approximately 1 in 10 patients (including 1 in 4 with acute ICH) will deteriorate between the scene and the ED arrival.

Many interventions for treatment of acute stroke are most effective when initiated as soon as possible after stroke onset.

True

False

4 / 19

Signs can alert the doctors to where the stroke occurred. Signs of stroke are important for EMS to document because it can provide a pre-notification report to the receiving hospital.

RACE stroke assessment includes Facial Palsy, arm strength, leg strength, gaze or head deviation, and:

Aphasia and agnosia

In trials, the increase in successful recovery was attributed to faster treatment times.

True

False

12 / 19

Stroke can affect: memory, senses, emotions, physical body.

True

False

13 / 19

How a stroke affects a person’s physiology depends on where the stroke occurred in the brain.

True

False

14 / 19

The majority of strokes are Ischemic.

True

False

15 / 19

Hemorrhagic stroke:

Blocks blood flow to an area of the brain

Does nothing to the brain

Is a bleeding that occurs inside or around brain tissue

Occurs in the heart.

Ischemic stroke:

Does nothing to the brain

Blocks blood flow to an area of the brain

Is a bleeding that occurs inside or around brain tissue

Occurs in the heart
