EMT: Cardiology and Resuscitation In the setting of acute stroke management, why is it important for EMTs to establish the last known well time of the patient? A. To determine eligibility for thrombolytic therapy B. To calculate the dose of antihypertensive medication C. To decide on the necessity of supplemental oxygen D.
