MDC4 Module 2 Flashcards
1
Q
What is the ABCD Assessment for TIA?
A
A - Age greater than or equal to 60 (stroke risk increases with age)
B - Blood pressure (BP) greater than or equal to 140/90 mm Hg (either systolic or diastolic or both)
C - Clinical TIA features (unilateral [one-sided] weakness increases stroke risk)
D - Duration of symptoms (the longer the TIA symptoms last, the greater the risk of stroke)
2
Q
What are the treatments for TIA?
A
- Performing traditional or minimally invasive surgery to remove atherosclerotic plaque buildup within the carotid artery and increaseperfusionto the brain
- Performing a carotid angioplasty with stenting to increaseperfusionto the brain
- Prescribing antiplatelet drugs, typically aspirin or clopidogrel, to prevent thrombotic or embolic strokes (may be placed on a combination of both drugs)
- Reducing high blood pressure (the most common risk factor for stroke) by adding or adjusting drugs to lower blood pressure
- Controlling diabetes (if present) and keeping glucose levels within a target range, typically 100 to 180 mg/dL
- Promoting lifestyle changes, such as smoking cessation, eating more heart-healthy foods, and increasingmobilityand physical activity
3
Q
What is a CVA/Stroke?
A
- CVA/Stroke is a change in normal blood supply (perfusion) to the brain
- A stroke (brain attack) is a medical emergency and should be treated immediately to reduce or prevent permanent disability
- The brain cannot store nutrients or O2, so constant flow is necessary to maintain homeostasis.
- If perfusion is interrupted, cerebral tissue dies (infarction)
- Effects on opposite side of the body
4
Q
What are the two types of stroke?
A
Ischemic Stroke: a clot blocking blood flow to an area of the brain
Hemorrhagic Stroke: bleeding inside or around brain tissue
5
Q
What are the two types of Ischemic Stroke?
A
Thrombotic and Embolic Stroke
6
Q
What is Thrombotic Stroke?
A
- A blood clot formation that blocks a blood vessel (atherosclerosis)
- Thrombotic stroke accounts for more than ½ of all strokes and is commonly related to atherosclerosis (in carotid arteries)
- When the clot is a sufficient size, blood flow is occluded
- Characterized by the GRADUAL onset of symptoms due to the slow nature of build up several minutes to hours.
