Step-by-step explanation:
The administration of a thrombolytic agent, such as alteplase, is a first intervention for someone who has suffered a thrombotic stroke. Alteplase helps to dissolve the clot that is causing the stroke, restoring blood flow to the brain. The sooner alteplase is administered after the client's arrival to the ED, the better the chances of a positive outcome. It is recommended to administer alteplase within 3 hours of the onset of stroke symptoms.
