Acute Stroke
Priority Actions and Care

When a stroke strikes, time is brain. Learn the time-sensitive priorities that protect neurons and save lives.

What Is a Stroke?

A stroke (cerebrovascular accident) occurs when blood flow to part of the brain is interrupted, depriving neurons of oxygen and glucose. Without flow, brain tissue begins to die within minutes.

Two Major Types

Ischemic (87%) Clot blocks vessel Hemorrhagic (13%) Vessel ruptures, bleeds

Recognizing Stroke: BE-FAST

B
Balance: sudden loss of balance or coordination
E
Eyes: sudden vision loss or double vision
F
Face: facial drooping, uneven smile
A
Arm: arm weakness or drift on one side
S
Speech: slurred or garbled speech, aphasia
T
Time: note the last known well time, call 911 immediately

The Time Window Rule

Eligibility for treatment depends on time since last known well (LKW) — the last moment the patient was seen functioning normally, NOT the moment symptoms were discovered.

LKW
tPA: \(\leq\) 4.5 hr
Thrombectomy: \(\leq\) 24 hr

Core Rule: Priority Sequence

When stroke is suspected, the nurse follows a strict order. Airway and circulation come before diagnostics; CT scan must precede any clot-busting therapy.

Assess ABCs protect airway Non-contrast CT scan Determine type Treat

tPA: Eligibility Checklist

Must Have
Ischemic stroke confirmed by CT, within \(4.5\) hr of LKW, age \(\geq 18\)
Exclusions
Any active bleeding, recent surgery, BP \(\gt 185/110\), platelets \(\lt 100{,}000\)
During Infusion
Frequent neuro checks, monitor for bleeding, no invasive procedures

Key Distinction: Blood Pressure

Ischemic (no tPA)After tPA / Hemorrhagic
BP goalPermit \(\leq 220/120\)Keep \(\lt 185/110\)
WhyMaintains perfusion to penumbraReduces bleeding risk
ActionTreat only if very highTreat aggressively

How to Apply: First 60 Minutes

1
Assess ABCs and protect the airway; position with head of bed flat or per protocol.
2
Establish LKW time and activate the stroke alert/team.
3
Obtain stat non-contrast CT, glucose, coags, and complete an NIHSS.
4
Keep NPO until a swallow screen is passed to prevent aspiration.
5
Manage BP per type and prepare tPA or thrombectomy if eligible.

Example 1: New Arrival

A 68-year-old arrives with sudden right-sided weakness and slurred speech. Last seen normal 90 minutes ago. What is the nurse's first priority action?

Example 2: During tPA

A patient receiving IV tPA suddenly develops a severe headache, vomiting, and rising blood pressure. What does the nurse do?

Example 3: BP Decision

An ischemic stroke patient (NOT a tPA candidate) has a BP of \(196/104\). The new graduate wants to lower it quickly. Is this correct?

Common Mistakes

✕ Giving food/fluids early
Patients must stay NPO until a swallow screen passes — aspiration risk is high.
✕ tPA before CT
Never give clot-busters until hemorrhage is ruled out by CT.
✕ Lowering BP too fast
In untreated ischemic stroke, permissive hypertension protects brain tissue.
✕ Using symptom-discovery time
Eligibility is based on last known well, not when symptoms were noticed.
