ATI MedSurg STUDY GUIDE (Safety) Seizure precautions Epilepsy During Protect the client’s privacy and the client from injury (move furniture away, hold head in lap if on the floor). Position the client to provide a patent airway. (Remember aspiration, turn head to side) Be prepared to suction oral secretions. Turn the client to the side to decrease the risk of aspiration. Loosen restrictive clothing. Do not attempt to restrain the client. Do not attempt to open the jaw or insert air...
