Study Tools For Stroke for Certified Emergency Nursing (CEN)
Outline
Stroke
Definition/Etiology:
I know that you know this, but a stroke occurs when something blocks blood supply to part of the brain or when a blood vessel in the brain bursts. In either case, parts of the brain become damaged or die.
Risk factors for stroke include, but are not limited to:
Hypertension, hyperlipidemia, A-fib, Diabetes, smoking, oral contraceptives, cardiac disease, and recent neck trauma.
Pathophysiology:
As we know, there are 2 types of strokes: Ischemic and hemorrhagic. We could get really deep into the patho behind each, but here is the important point: Ischemic stroke is caused by deficient blood and oxygen supply to the brain; hemorrhagic stroke is caused by bleeding or leaky blood vessels.
Clinical Presentation:
Signs of ischemic stroke –
Sudden onset of:
- Unilateral facial weakness
- Unilateral weakness of the arm or leg
- Expressive or receptive aphasia, or both
- Headache, nausea, vomiting
- Vertigo, ataxia
- Visual disturbances
- Numbness or tingling
Hemorrhagic stroke signs:
- The above as well as
- Rapidly decreasing level of consciousness – leading to possible coma
- HTN
Findings more common with a bleed: N/V, photophobia, phonophobia
Collaborative Management:
- CODE STROKE (or whatever your facility calls it)
- Need immediate CT to determine type and location of stroke
- Lab work – CBC, CMP, Coags, cardiac enzymes if cardiac related
- Blood Glucose
- Neuro or neurosurge involvement
- NIHSS
- Determine need for TPA
- If GCS <8, intubate?
- 2 large bore IV
- O2
Evaluation | Patient Monitoring | Education:
- Frequent, frequent, frequent neuro checks
- NIHSS
- GCS
- Determine effectiveness of TPA – follow hospital protocols
- Antihypertensive meds – Do not drop too low. Maintain SBP <185 and DBP <110
Linchpins: (Key Points)
- Time is brain
- What type
- Frequent reassessments
