A nurse is caring for a client who is experiencing a seizure. Which of the following actions should the nurse take?

A. Leaving the client alone during a seizure is unsafe; the nurse should stay and ensure the client’s safety. B. Placing a towel under the client's head helps protect the client from head injury during the seizure without restricting movement. C.
