Stroke NGN Case Study

Most concerning cues: sudden focal deficits — facial droop, unilateral arm and leg weakness, slurred speech — the BE-FAST core. Sudden onset is the word that matters: strokes announce themselves in seconds to minutes.

The two golden details: a witnessed last known well of 0810 (a reliable clock makes her a potential thrombolytic candidate — it’s 0910 now, about one hour in) and atrial fibrillation off anticoagulation — the textbook setup for a cardioembolic ischemic stroke.

The cue hiding in a question: the daughter offering water. Nothing by mouth until a swallow screen passes — aspiration is one of the most preventable stroke complications.

Ischemic stroke (most supported): afib without anticoagulation makes an embolic clot the leading explanation for sudden unilateral deficits.

Hemorrhagic stroke: clinically indistinguishable at the bedside — which is exactly why the non-contrast head CT is the gatekeeper. Thrombolytics given into a bleed are lethal; nothing clot-busting happens before the scan.

Hypoglycemia — the great mimic: a fingerstick glucose is the other mandatory check; low sugar can produce focal deficits that resolve with dextrose. Hers is 132 — ruled out.

Also on the list: seizure with Todd’s paralysis, migraine variants — kept in mind, but a witnessed sudden onset in an afib patient doesn’t wait on them.

1. Acute ischemic stroke within the treatment window — probable, lethal to brain tissue by the minute (“time is brain”), and uniquely time-gated: IV thrombolysis is generally limited to within 3–4.5 hours of last known well, and large-vessel occlusions may also be thrombectomy candidates. Every workflow decision bends around that clock.

2. Hemorrhagic stroke — less likely but catastrophic to miss; the CT result flips the entire treatment plan, so it happens before anything else.

NGN logic: when one hypothesis carries a closing time window, speed itself becomes a priority — the evaluation is run in parallel (CT, labs, NIHSS together), not in sequence.

Immediate: activate the stroke alert; stat non-contrast head CT (the single rate-limiting step); fingerstick glucose (done — 132); NIHSS by a certified assessor; two IV lines; labs (CBC, coags, BMP) drawn without delaying the scan; accurate weight (tPA is weight-based); cardiac monitor (her afib is already showing).

Protect her while the clock runs: NPO until a swallow screen, head of bed per protocol, fall precautions, frequent neuro checks — and keep the daughter close: she is the time-of-onset witness and the history source.

Anticipate the eligibility screen: the team will run thrombolytic inclusion/exclusion criteria — recent surgery, bleeding history, anticoagulant use (she stopped hers — in this case that removes an exclusion), BP thresholds (generally must be below ~185/110 before tPA, managed with IV agents if needed).

Intensive monitoring: neuro checks and vitals on the post-tPA schedule (typically q15min ×2h, then q30min ×6h, then hourly), with BP kept below ~180/105 — hypertension into a freshly lysed brain risks hemorrhagic conversion.

Bleeding vigilance: any neuro decline, new severe headache, vomiting, or acute hypertension = suspect intracranial hemorrhage → stop any infusing thrombolytic, stat CT, call the team. Also watch gums, IV sites, urine, and for angioedema (tongue/lip swelling — airway risk, higher in patients on ACE inhibitors).

Hold the blood thinners: no anticoagulants or antiplatelets for the first 24 hours post-tPA; no unnecessary lines, injections, or invasive procedures. Swallow screen before anything by mouth. Her afib anticoagulation conversation comes later — and matters enormously for preventing the next stroke.

Improving: the falling NIHSS is the objective marker — reperfusion salvaged threatened brain. No hemorrhagic conversion through the highest-risk window, BP controlled.

Still watching: the 24-hour follow-up CT before starting antithrombotics, swallow function before diet advancement, mood (post-stroke depression is common and undertreated), and mobility/fall risk as she re-engages.

Not resolved — and the honest answer to the daughter: the deficit is improving, not erased, and the cause is untreated. Secondary prevention is the discharge mission: restarting anticoagulation for afib (addressing the bruising concern that made her quit), BP control, rehab referrals, and BE-FAST teaching for the whole family — they caught this one fast; they should know exactly what they did right.
