Why would we want to bring a witness with us during a STROKE / TIA call?

• A. To keep the patient company
• B. To verify time of onset and provide consent for interventions; if witness unable to ride in ambulance, obtain accurate contact phone number
• C. To document the call for quality improvement
• D. To assist with lifting the patient into the ambulance

Answer: (B)

The key idea here is that timing matters a lot in stroke care. A witness helps establish exactly when symptoms started, or when the patient was last known well, which is critical for deciding if a patient is within the treatment window for interventions like thrombolytics. A witness can also speak to the patient’s known preferences or obtain information the patient cannot provide due to impairment, aiding consent decisions in an emergency.

That’s why the best choice emphasizes verifying onset time and providing information for consent. If the witness can’t ride in the ambulance, collecting an accurate contact number ensures we can reach someone who can confirm onset timing and help with decisions after transport.

Other options miss the clinical point: keeping the patient company doesn’t influence urgent treatment decisions; documenting the call for quality improvement happens, but it’s not the purpose of bringing a witness in; and assisting with lifting isn’t about the clinical information needed for stroke care.
