B. Restrain the client's arms and legs: Restraining a client during a seizure is not advised, as it can cause injury. Instead, the focus should be on protecting the client from harm.

C. Place a tongue blade in the client's mouth: Placing anything in the client’s mouth during a seizure is contraindicated, as it can lead to airway obstruction or injury.

D. Take measures to prevent injury: The priority during a seizure is to protect the client from injury by ensuring a safe environment, such as padding the head and moving any dangerous objects away.
