Chapter 6 - Acquired Brain Injury Flashcards
(44 cards)
Stroke is also known as:
Cerebrovascular accident, which occurs when blood supply to the brain is disrupted.
Ischaemic stroke -
Due to a blocked artery can be caused by either an emboli or a thrombus.
Haemorrhaging stroke -
Bleed out in brain, blood vessel ruptured.
Risk factors for stroke include:
Hypertension Obesity Cigarette smoking Diet high in cholesterol Alcohol Lack of exercise Diabetes Atrial fibrillation
APPT is a clothing measure of bloods and stands for:
Activated partial thromboplastin time
A normal GCS is:
15
Stroke should be considered a medical emergency as:
Diagnosis and treatment with tPA needs to occur within four and a half hours from onset of symptoms
A thrombus which has broken loose and is moving with the blood flow is called:
An embolism
Atheroma is:
Fatty plaque on the wall of an artery
A stroke-in-evolution is:
A thrombotic stroke that occurs rapidly but then progresses slowly over 2-3 days.
The immediate treatment for a stroke includes:
Receiving a thrombolytic in the Emergency Department once a CT scan has been done.
Which is the most important goal in the immediate phase of acute stroke care?
Minimal damage to the penumbra and re-establish perfusion as quickly as possible.
Difference between the systolic and diastolic pressure is called the:
Pulse pressure
4 common cues during stroke :
Pattern of breathing
Headache
Nausea/vomiting
Presence of papilloedema
List three factors that can impair cerebral auto regulation:
- Increase arterial pressure
- Increased hydrogen ions from increased CO2
- A fall in Pa02
What are the two major arteries supplying the brain?
Cerebral and vertebral
Cushings triad is associated with:
Raised intracranial pressure
Three parameters that form cushings triad:
- Raised pulse pressure
- Decreased pulse
- Abnormal breathing pattern
Mannitol is an osmotic diuretic. It would be most likely to be given for:
Cerebral oedema
The rigid cranial cavity contains three non-compressible elements:
- The brain 80%
- CSF 8%
- Blood 12%
The Monroe - Kellie hypothesis is when:
Any of the 3 components increases, the volume of the others must decrease to maintain equilibrium. (Brain, CSF, Blood)
Normal intracranial pressure is:
0-10mmHg
3 signs which usually are not causative of confusion and altered level of consciousness:
- Hypertension
- Hypo/hyoerkalemia
- Hyponatraemia
Which of the folllowing is not a risk factor for developing artherosclerosis?
- Male
- Diabetes
- Smoking
- High HDL level
- High dietary fat intake
High HDL level
