Stroke and Neurologic Red Flags

Stroke items reward the nurse who recognizes a sudden neurologic change and moves fast. The exam rarely asks you to name a lesion — it asks whether you can spot the red flag, protect the airway, and get the patient to treatment before the window closes.

Core Decision Rule

• Sudden, focal neurologic change is an emergency until proven otherwise. New weakness, facial droop, slurred speech, or a sudden severe headache outranks stable and chronic complaints every time.
• Time is brain — establish last-known-well immediately. Treatment eligibility depends on how long ago symptoms started, so rapid recognition and escalation matter more than a leisurely head-to-toe assessment.
• Airway and safety come before workup. An unstable neurologic patient can lose the gag reflex and deteriorate quickly, so protect the ABCs first.

BE-FAST Recognition

BE-FAST is the high-yield tool for catching a stroke at the bedside:

• B — Balance: sudden loss of balance, dizziness, or coordination.
• E — Eyes: sudden vision loss, double vision, or a visual field cut.
• F — Face drooping: ask the patient to smile; look for one-sided droop.
• A — Arm weakness: ask them to raise both arms; one drifts down.
• S — Speech difficulty: slurred, garbled, or absent speech (aphasia).
• T — Time: note the time of onset or last-known-well and escalate now.

The single most important data point you gather is when the patient was last normal. That last-known-well time, not the time symptoms were discovered, determines whether time-sensitive treatments are still an option.

Ischemic vs. Hemorrhagic

Both types present with sudden deficits, but the story differs. An ischemic stroke (a clot) is the most common type and often unfolds as sudden focal weakness or speech loss. A hemorrhagic stroke (a bleed) classically arrives with a sudden, severe "worst headache of my life," often with nausea, vomiting, and a rapidly declining level of consciousness. On the exam, "worst headache ever" plus neurologic change points you toward a bleed. The nurse does not distinguish these at the bedside — imaging does — but recognizing the hemorrhagic pattern reinforces urgency and shapes blood-pressure and positioning decisions.

Airway, Aspiration, and Swallowing

A stroke can wipe out the swallow reflex, making aspiration a leading complication. The safe rule: keep the patient NPO until a swallow screen is passed. Do not offer food, fluids, or oral medications — not even sips of water — before swallowing is cleared. Keep suction available, watch for pocketing of food, coughing, or a wet, gurgly voice, and position to protect the airway if the level of consciousness drops.

Positioning, Blood Pressure, and ICP Red Flags

Positioning and pressure are judgment calls tied to the type of stroke and the patient's status. Elevating the head of the bed and keeping the neck midline supports venous drainage and airway protection when intracranial pressure is a concern. Blood pressure is often permitted to run somewhat high in acute ischemic stroke to keep the brain perfused, so an elevated reading is not automatically "treat now" — follow the provider's parameters rather than reflexively lowering it. Watch relentlessly for rising intracranial pressure (ICP): a declining level of consciousness, new or unequal pupils, a sluggish pupil response, or projectile vomiting. The late and ominous Cushing's triad — rising systolic pressure with a widening pulse pressure, bradycardia, and irregular breathing — signals dangerous ICP and demands immediate escalation.

High-Value NCLEX Patterns

• Choose the patient with the newest, most sudden neurologic deficit before stable or chronic complaints.
• "Sudden worst headache of my life" plus neurologic change signals a possible hemorrhagic bleed — treat as an emergency.
• The first action for a new stroke sign is usually to protect the airway and establish last-known-well time, then escalate.
• A declining level of consciousness or a new pupil change is a rising-ICP red flag — act, do not wait and reassess.
• Keep the patient NPO until the swallow screen passes; withhold oral meds and fluids.

Common Distractors to Avoid

• Giving water, food, or oral medications before swallowing is screened.
• Aggressively lowering a high blood pressure in acute ischemic stroke without provider parameters.
• Choosing "document and reassess later" over immediate escalation for a sudden deficit.
• Anchoring on a chronic migraine or old numbness while missing a quiet new change.
