Question

TPA must be given within how many hours of stroke? a) 1 hour

b) 3 hours
c) 6 hours
d) 12 hours

Answer 1

The administration of a thrombolytic agent is the first intervention for someone who has suffered a thrombotic stroke. TPA must be given within 3 hours of a stroke for it to be effective. If administered within this time frame, TPA can help restore blood flow and prevent permanent brain damage.

Step-by-step explanation:

The administration of a thrombolytic agent is the first intervention for someone who has suffered a thrombotic stroke because these drugs help break down blood clots that are blocking blood flow to the brain. Tissue plasminogen activator (TPA) is a commonly used thrombolytic agent. It works by converting plasminogen to plasmin, which breaks down clots.

TPA must be given within 3 hours of a stroke for it to be effective. If administered within this time frame, TPA can help restore blood flow to the brain and potentially prevent permanent brain damage.

It is important to recognize the signs of a stroke and seek medical attention immediately for timely treatment.
