Final answer:
The mandatory test before administering tPA is a Noncontrast CT brain scan, to exclude hemorrhagic stroke. Rapid neurological assessment helps diagnose and manage stroke promptly. Thrombolytic agents like tPA are critical for dissolving clots in thrombotic strokes.
Step-by-step explanation:
The only mandatory test before administering tissue Plasminogen Activator (tPA) is a Noncontrast CT brain scan. This scan is required to rule out a hemorrhagic stroke, which is a contraindication for tPA administration. Administering tPA in cases of hemorrhagic stroke increases the risk of bleeding and can be harmful to the patient. Therefore, confirming the absence of hemorrhage through a CT scan is crucial before the treatment with tPA can commence in the case of ischemic stroke.
A rapid assessment of neurological function is crucial in an emergency situation as it helps in identifying the location and extent of a neurological injury, such as a stroke. By evaluating motor control, reflexes, and sensory responses, medical professionals can promptly diagnose and manage the condition, which is pivotal in improving the patient's chances of recovery. Administering a thrombolytic agent, like tPA, as a first intervention for someone who has suffered a thrombotic stroke is vital because it aids in dissolving the clot that is blocking the flow of blood to the brain, restoring circulation, and minimizing brain damage.
