Question

Window to give TPA in acute ischemic stroke:

a) Within 3 hours of symptom onset
b) Within 4.5 hours of symptom onset
c) Within 6 hours of symptom onset
d) Within 9 hours of symptom onset

Answer 1

The window to administer TPA for treating an acute ischemic stroke is within 4.5 hours of symptom onset. Rapid administration of TPA can greatly improve outcomes, and quick recognition of stroke symptoms using FAST is critical.

Step-by-step explanation:

The window to give tissue plasminogen activator (TPA) in an acute ischemic stroke is within 4.5 hours of symptom onset. TPA is used as a clot-busting drug and is crucial for improving the prognosis of stroke victims. Recovery from a stroke or transient ischemic attack (TIA), which is a temporary loss of neurological function, greatly depends on the speed of TPA administration, as this leads to the degradation of the abnormal clot blocking blood flow to the brain. Recognizing a stroke quickly with the help of the mnemonic FAST (Face drooping, Arm weakness, Speech difficulty, Time to call emergency services) is vital for prompt treatment and can mitigate long-term disabilities associated with strokes.
