Question

if you think someone might be having a stroke, what should be the first thing you do?
quickly check for signs of stroke
start first aid on the individual
give the person an injection of alteplase.
wait an hour and then phone 9 - 1 - 1

Explanation:

When suspecting a stroke, the first step is to quickly check for signs (e.g., using FAST - Face drooping, Arm weakness, Speech difficulty, Time to call). Starting first aid without confirmation may be incorrect. Alteplase is a prescription drug not for lay - person injection. Waiting wastes critical time as stroke treatment is time - sensitive.

Answer:

Quickly check for signs of stroke
