Final answer:
The client's statement indicating high risk of stroke after a transient ischemic attack (TIA) is incorrect. They need further education on their individual risk factors and steps to reduce the risk.
Step-by-step explanation:
Out of the given statements, the client's statement: "I now have a high risk of stroke since I've had a transient ischemic attack." indicates a need for further education. While a transient ischemic attack (TIA) is often considered a warning sign for a future stroke, it does not guarantee a high risk of stroke. It is essential to provide the client with accurate information regarding their individual risk factors and steps they can take to reduce their risk of stroke.
