Noting the last seen normal informs decisions about which therapy?

• A. Physical therapy
• B. Thrombolytic therapy
• C. Antibiotic therapy
• D. Pain management

Answer: (B)

Noting the last seen normal time is crucial because thrombolytic therapy must be given within a limited, defined window after stroke symptoms start. The goal of thrombolysis is to dissolve the clot early enough to restore blood flow and reduce brain damage, but giving it too late raises the risk of serious bleeding. Clinicians use the last time the patient was normal to determine eligibility—typically within about 4.5 hours for IV thrombolysis, with some flexibility guided by imaging in certain cases. If the onset time isn’t within that window or is unknown, thrombolysis is usually not given, though imaging might allow treatment in selected wake-up or uncertain-onset strokes. Other therapies—rehabilitative physical therapy, antibiotics, or pain management—are guided by different factors and are not primarily determined by how long ago the patient was last normal.
